PowerColor X1600 XT & X1300

While I can easily say both X1600 XT and X1300 from PowerColor are good products, I’m a bit famished. The performance of X1600 XT could be better yet I understand this might come in time with the new drivers. This X1600 as well as X1300 have it all; Avivo/HDTV along with H.264 decoding and transcoding, new Ultra-Threaded Shader Engine, Ring Bus memory controller (XT only) and most importantly Shader Model 3.0 support. RADEON X1600 doesn’t stay way behind the pack. As far as I’m concerned it’s performing properly for $200 bucks, but lacks that true 256-bit bus. The next gem, PowerColor X1300 is aimed at consumers with less money on hand or simply those who need advanced DirectX 9 support at a reasonable price / performance ratio.

Introduction

*Important update*

It has come to my attention that Tul does not carry a regular X1300 PRO. Instead it has its Bravo model with custom cooling device. The PRO model with golden heatsink you see on their product page does NOT exist.

What Tul is doing is they are providing customers with an OC BIOS. When you flash your regular PowerColor X1300 (400 MHz / 250 MHz) it will be clocked to PRO speeds (600 MHz / 400 MHz). This was exactly the card I have gotten — a non PRO flashed with PRO clockrates. What does that mean? Both PRO and non PRO models are equipped with the same type of memory, capable of 800 MHz DDR speeds. does NOT exist. Since I wasn’t aware of this fact, I assumed it was a PRO model based on the specifications on their website. The card I have received is indeed a retail product.

PowerColor X1300 to X1300 PRO BIOS mod (rar, 120KB)

X1300’s (R51B-ND3) default clocks are 450 MHz / 250 MHz. After the flash they will match X1300 PRO speeds: 600 MHz / 400 MHz!

Instructions (use the included ATIFLASH utility):

Backup your BIOS: atiflash -s 0 <BIOS name>.sb -f (ex. backup.sb)
Reflash BIOS: atiflash -p 0 x1300oc.sb -f (x1300oc.sb is the new BIOS)

Reboot and enjoy your brand new PowerColor X1300 PRO 🙂

About a month ago I’ve reviewed a flagship card from PowerColor: X1800 XT with all the bells and whistles; that is Avivo, new memory bus and SM 3.0 support. Based on the new R520 core, ATI tried to climb up and reach G70 performance. In some cases it succeeded, but whether you like it or not it’s losing the battle in a lot of scenarios. Comparing it to last year’s X800 generation it does sport significant performance boost over the old high-end card however.

Today I have less expensive parts to test for both middle and low-end sectors of the market. They are PowerColor X1600 XT and X1300. The first card is based around RV530 core. There should be a lot of different SKUs mainly because ATI allows for handful of configurations ie. memory size and type. As far as memory bus is concerned, it features two 128-bit rings which is essentially a 128-bit architecture (ATI calls it 256, but that’s obviously wrong). It comes with 4 pixel pipelines, 12 pixel shader units and 5 vertex pipelines — not a standard 1:1 configuration. The X1300 sample is equipped with 4 pixel pipelines, 4 pixel shader units and 2 vertex pipelines (1 to 1 ratio, just like R520). As with X1600 XT it’s also a 128-bit offering and should be available in many different configurations.

Should you require more detailed information on X1K please revisit our article: The X1000 series – ATI goes SM3.0

For those not in the know Tul Corporation is a Tier-1 provider of ATI-based graphic cards. The company is also a leader in providing motherboards and barebone systems. So what about PowerColor?


PowerColor is a consumer brand focused on providing cutting-edge graphics card products to retail customers. Our goal for the Tul brand is to be the industry’s number one provider of technology product solutions. Our goal for the PowerColor brand is to be the world’s number one brand of graphics cards. PowerColor is in effect owned by Tul Corporation, however the brands are operated independently of each other.

VPU Specifications

As with every new generation of GPUs the feature set becomes larger and more complex. The newly introduced X1K family of products is exactly what we have here. Most importantly, the X1000 line now sports Shader Model 3.0 which has been available from NVIDIA for over a year now. The X1600 GPU is similarly designed as X1800, but with few important differences. It uses 128-bit memory bus and features different pipeline architecture. The card boasts 4 pipelines (known as ROPs, Render Output Pipelines). Do not get confused (as I did), I’ll explain.

ROPs are actual pixel pipelines. Shader pipelines or pixel shaders consist of ROPs and fragment pipelines. With X1600, each ROP consists of 3 pixel shaders (giving us 12 PS units) and 8 Z-samples per clock. In other words X1600’s pipeline configuration is as follows:

  • 12 PS units
  • 4 ROPs
  • 4 TMUs (1 TMU per pipeline)
  • 8 Z-samples per clock

The biggest of all changes is the introduction of what ATi calls Ultra-Threading Dispatch Processor and Ring Bus (old SMARTSHADER). Without going into much detail here, the dispatch processor (as the name implies) routes or relegates the workload to four pixel shader cores (also known as Quads). Each quad consists of four mini-pixel processors. The process between them is called threading and means:

  • Large Scale Multi-threading
    • Hundreds of simultaneous threads across multiple cores
    • Each thread can perform up to 6 different shader instructions on 4 pixels per clock cycle
  • Small Thread sizes
    • 16 pixels per thread in Radeon X1800
    • Fine-grain parallelism
  • Fast Branch Execution
    • Dedicated units handle flow control with no ALU overhead
  • Large Multi-Ported Register arrays
    • Enables fast thread switching

Now the Ring Bus technology. This isn’t Marry-go-around or anything like that — well sort of. The bus itself consists of two 128-bit rings which run in the opposite direction. This way routing latencies are reduced to a bare minimum and clockrate scaling is far more efficient. Among other things we have:

  • New cache design – fully associative for more optimal performance
  • Improved Hyper-Z – better compression and hidden surface removal
  • Programmable arbitration logic – maximizes memory efficiency and can be upgraded via software

Important note: X1300 GPU does not carry a Ring Bus! It uses different technique to improve memory allocation.

The Card: PowerColor X1600 XT

With high-end cards getting ridiculous big it’s quite often that users will go with less powerful graphics chip and get smaller boards instead. Usually middle and low-end cards are 1 slot designs with rather standard cooling. That is the case with PowerColor X1600 XT and X1300.

Focusing on the top image reveals the size of X1600 XT. The GPU is covered by a reference ATI HSF — actually I consider the whole card a reference design as there are no signs of PowerColor branding, except for stickers on the back of the PCB. Also there is no external power socket so you don’t have to worry about additional enerby being fed to the GPU.

Size wise the PCB is similar to that of RADEON X800. The cooling device is held in place by a 4-armed plate.

Our PowerColor X1600 XT exhibits dual DVI-I outputs as well as S-Video out. The card carries a standard display support: VGA compatible, VESA compatible BIOS for SVGA and DDC 1/2b/2b+

As for memory…well it’s not SAMSUNG though still good GDDR3 memory chips: Infineon HYB18H512321AF-14 (TFBGA-136 rated at 700 MHz). They overclock past that speed. More on that later.

The Card: PowerColor X1300

*Important update*

It has come to my attention that Tul does not carry a regular X1300 PRO. Instead it has its Bravo model with custom cooling device. The PRO model with golden heatsink you see on their product page does NOT exist.

What Tul is doing is they are providing customers with an OC BIOS. When you flash your regular PowerColor X1300 (400 MHz / 250 MHz) it will be clocked to PRO speeds (600 MHz / 400 MHz). This was exactly the card I have gotten — a non PRO flashed with PRO clockrates. What does that mean? Both PRO and non PRO models are equipped with the same type of memory, capable of 800 MHz DDR speeds. does NOT exist. Since I wasn’t aware of this fact, I assumed it was a PRO model based on the specifications on their website. The card I have received is indeed a retail product.

The low-end segment is probably the most popular one. OEMs tend to put in their systems rather slow cards to cut the cost of the whole package. We at Bjorn3D don’t review many of those cards, but along came the opportunity so I couldn’t resist.

The dimensions should not scare anyone away. The board is small and will fit into any system with PCI-Express port. The cooling slapped on X1300 is also a reference design, just as with X1600 XT.

This particular card is equipped with 256 MBs of memory which doesn’t make a huge difference performance wise. Albeit if you feel the need for higher resolution textures, additional RAM will help you achieve it.

Just as X1600 XT, PowerColor X1300 sports dual DVI-I outputs (not seen on many low-end boards) as well as TV-out. The card carries a standard display support: VGA compatible, VESA compatible BIOS for SVGA and DDC 1/2b/2b+

PowerColor X1300 / PRO uses Hynix GDDR2 memory: HY5PS561621AFP-25 rated at 400 MHz inside 84Ball FBGA package.

X1600 XT and X1300 together

As far as installation goes I cannot report any problems. Both cards booted up nicely without a hitch, except for that annoying fan noise which lasts around 3-5 seconds. That’s when the fan spins at maxium RPM.

Synthetic Benchmarks

3DMark05

I’ve used Futuremark’s 3DMark 2005 to measure the actual throughput of both PowerColor X1600 XT as well as X1300 and compared it against a few other candidates: X700 and X800 XT. Below are the results.

Video card
PowerColor X1600 XT PowerColor X1300
Bravo X700 ATi X800 XT
Pixel Fillrate 2055,2 MPixels /sec
1017,5 MPixels / sec 957,1 MPixels / sec 3284 MPixels / sec
Texel Fillrate 2351,6 MTexels / sec
1689,3 MTexels / sec 3184 MTexels / sec 7943 MTexels / sec
Geometry Rate 590 MTriangles
600 MTriangles
400 MTriangles 500 MTriangles
Vertex Shader – Simple 73,2 MVertices / sec
45,2 MVertices / sec 32,5 MVertices / sec 58 MVertices / sec
Vertex Shader – Complex 47,1 MVertices / sec 15,7 MVertices / sec 34,8 MVertices / sec 46 MVertices / sec
Pixel Shader (2.0b) 113,4 FPS
33,5 FPS 53 FPS
140 FPS

With only 4 ROPs, X1600 XT does not perform as well as X700 which features 8 Render Output Pipelines and X800 XT sporting 16 of those. The obvious and staggering difference is texel fillrate which is even less than X700’s. Although RV530 has only 4 ROPs it features 12 Pixel Shader pipelines which help in PS intensive applications. X1300 also has 4 ROPs, but 4 Pixel Shader units instead.

With added SM 3.0 support, X1600 XT does pretty good in 3DMark05 with default settings. It’s around 50% faster than X1300 and X700 and around 20-25% quicker than RADEON X800 GT equipped with 8 Pixel Shader units.

RightMark

D3D RightMark is a very useful tool for measuring different theoretical throughputs of a graphics chip. I ran couple of synthetic tests to stress out X1600 XT / X1300. The main focus of theses tests will be to stress out Geometric Processing (Vertex Shading) as well as Pixel Shader units.

With D3D RightMark you will be able to get the following information about your video card:

  • Features supported by your video card
  • Pixel Fillrate and Texel Fillrate
  • Pixel shader processing speed (all shader models)
  • Vertex shader (geometry) processing speed (all shader models)
  • Point sprites drawing speed
  • HSR efficency

In this test, we are looking at the vertex shader’s (geometry) processing speed. I chose Diffuse + specular (3 point lights) for our lightning profile which is probably the most useful setting. This will give us peak geometrical throughput. In order to get a clearer overlook, three different shader profiles were used: Fixed Function Pipeline (FFP) VS1.0 and VS 2.0 flow control.

The difference between the two tested cards is pretty substantial. RADEON X1600 is aimed at the middle-end market while the X1300 is pushed through the low-end channel. PowerColor X1600 XT performs better by around 35-41%. Let’s see how those cards deal with pixel shading tests.

As expected, though not by much, X1600 XT leads with 100 FPS at both 16 / 32-bit FP. PowerColor X1300 ends up with 82 FPS.

F.E.A.R

On August 5th this year, VUGames have released F.E.A.R demo to the public. The game is being made over at Monolith Productions studio and should be out later this year. Since almost everyone has been waiting for this demo, I’ve decided to give it a shot and bench it with X1600 XT and X1300 from PowerColor.

Texture caching in retail F.E.A.R has been improved a little. You won’t see a lot of chugging when abruptly turning around. Our benchmarking method was simple. I used default F.E.A.R benchmarking utility which nicely shows all effects and technology used throughout the game.

Game Overview

An unidentified paramilitary force infiltrates a multi-billion dollar aerospace compound, taking hostages but issuing no demands. The government responds by sending in special forces, but loses contact as an eerie signal interrupts radio communications. When the interference subsides moments later, the team has been obliterated. As part of a classified strike team created to deal with threats no one else can handle, your mission is simple: Eliminate the intruders at any cost. Determine the origin of the signal. And contain the crisis before it spirals out of control.

As you probably know, F.E.A.R uses a very sophisticated game engine (FEAR).

  • Rendering
    • FEAR is powered by a new flexible, extensible, and data driven DirectX 9 renderer that uses materials for rendering all visual objects. Each material associates an HLSL shader with artist-editable parameters used for rendering, including texture maps (normal, specular, emissive, etc.), colors, and numeric constants.
  • Lightning Model
    • FEAR features a unified Blinn-Phong per-pixel lighting model, allowing each light to generate both diffuse and specular lighting consistently across all solid objects in the environment. The lighting pipeline uses the following passes:
      • Emissive: The emissive pass allows objects to display a glow effect and establishes the depth buffer to improve performance.
      • Lighting: The lighting pass renders each light, first by generating shadows and then by applying the lighting onto any pixels that are visible and not shadowed.
      • Translucency: The translucent pass blends all translucent objects into the scene using back to front sorting.
  • Visual Effects
    • FEAR features a new optimized, data driven effects system that allows for the creation of key-framed effects that can be comprised of dynamic lights, particle systems, models, and sounds. Examples of the effects that can be created using this system include weapon muzzle flashes, explosions, footsteps, fire, snow, steam, smoke, dust, and debris.
  • Sample Lights
    • FEAR’s lighting model is very flexible and allows developers to easily add new lights. Existing lights include:
      • Point Light: The point light is a single point that emits light equally in all directions.
      • Spotlight: Similar to a flashlight, the spotlight projects light within a specified field of view. The spotlight can also use a texture to tint the color of the lighting on a per pixel basis.
      • Cube Projector: Similar to the point light, the cube projector uses a cubic texture to tint each lit pixel.
      • Directional Light: This lighting is emitted from a rectangular plane and is used to simulate directional lights like sunlight.
      • Point Fill: Although similar to the point light, the point fill is an efficient option because it does not utilize specular lighting or cast shadows.

A more detailed overview of other F.E.A.R technologies can be found over at Touchdown Entertainment. These include: Havok Physics Engine and Modeling / Animations System.

Running both cards with the same settings would not be a cool idea so I’ve decided to custom pick the quality for X1600 XT. I would say they were set to medium high with few settings off or at low (volume lights for example, texture and water resolution set to medium). PowerColor X1300 received auto detect settings with additional volume lights off.

Concentrating on scores, X1600 XT does 66 FPS at 8×6 (X1300 gets 47 FPS). I haven’t included scores at 16×12 for X1300 because they were…well…miserable. After all it’s a low-end card so you shouldn’t expect flawless performance — especially with F.E.A.R.

Enabling AA and AF takes both cards to their knees. It was even pointless to run X1300 at 12×9 and 16×12. X1600 XT scored 54 FPS at 8×6 and 33 at 10×7. Overall better by ~37-40%

Half-Life 2

We all love Half-Life 2 and we all want best performance out of our hardware. This has to be one of the most graphic demanding games currently on the market. Half-Life 2 is built around Source engine which utilizes a very wide range of DirectX 8 / 9 special effects. Those include:

  • Diffuse / specular bump mapping
  • Dynamic soft shadows
  • Localized / global valumetric fog
  • Dynamic refraction
  • High Level-of-Detail (LOD)

Note that users with DirectX 7 and older hardware (NVIDIA MX series for example) will not be able to enjoy the above effects. Let’s see how middle-end / low-end X1K graphic cards perform.

At 8×6 both cards are doing pretty well. Moving up the resolution increases the gap between X1600 XT and X1300. The middle-end board does from 11 to 49% better than its cheaper brother.

With Antialiasing and Anisotropic Filtering turned, X1300 stops outputting reasonable framerates at 12×10 and 16×12. RADEON X1600 XT with its 12 pixel shading units and 4 real pipelines gets as low as 26 FPS at 16×12. Overall both cards did well at medium quality, X1600 XT obviously performing better with AA and AF enabled.

Doom 3

Now that we are past Doom 3s release, some gamers have been left with a bit of disappointment. Main reason is Half-Life 2 and its Source engine which really showed a vast amount of potential and scalability.

Although this game needs no introduction, I will go over some of the game features and technology behind Doom 3. It took the guys at id Software over four years to complete this project. Lead programmer, John Carmack spent an awful lot of time designing the game engine, but his hard work paid off — to some extent since this is first title which houses Doom 3 engine.

Let’s look at some of the engine tech features which are present in Doom 3:

  • Unified lightning and shadowing engine
    • Dynamic per-pixel lightning
    • Stencil shadowing
    • Specular lightning
  • Realistic bumpmapping
  • Dynamic and ambient six-channel audio

However you look at it, Carmack’s lightning engine is the essence of Doom 3. With OpenGL being the primary API, shaders have been put to a heavy use in order to create the realisticly looking environment. Instead of using lightmaps the game engine now processes all shadows in real-time. This technique is called stencil shadowing which can accurately shadow other objects in the scene. There are disadvantage to this method however:

  • Requires a lot of fillrate
  • Fast CPU is needed for shadow calculations
  • Inability to render soft shadows

Instead of using high-end profile I decided to bench both X1600 XT / X1300 at medium settings — with higher texture compression and no Anisotropic Filtering, just Trilinear.

Talking about playable framerates, both GPUs receive fruitful results; RADEON X1600 XT performing better than X1300 by as much as 39% The last resolution was an overkill for poor low-end’er.

The fun part starts here, where I enable 4xAA and 8xAF quality modes. PowerColor X1300 holds its feet at 800×600, but cannot resist the higher resolutions: 12×10 and 16×12. The middle-end market GPU gets a playbale 42 FPS at 10×7 and ends up with 20 FPS at the highest resolution of 16×12.

Need For Speed: Most Wanted

We have quite a few sequels in this review and this is another one, this time from Electronic Arts. If you’ve played NFS Hot Pursuit you know what I’m talking about. There are a lot of ideas taken out from the older NFS. The main difference between Most Wanted and Underground (in terms of graphics) is addition of HDR-type effects. It’s pseudo-HDR (more like bloom), but looks lovely nonetheless. Additionally the game sports flashy new reflections, better object geometry, improved lightning system and finally physics engine.

Here we have a fresh new title with bells and whistles waiting to get benched.

Although medium quality puts the slider in the middle, you are welcome to fiddle around and customize your settings. However I have found, that for both cards this is the best mode. Without further delay, check out the scores. At 8×6 both X1600 XT and X1300 perform great. There is a quite a hit with X1300 when moving up the resolution — 16×12 seemed not playable at all. For X1600 XT, 10×7 is the best option here.

If you fancy some jaggy-free edges and crispy textures, turn on that Full Scene Anti-Aliasing and Anisotropic Filtering. With X1600 XT both 8×6 and 10×7 were fully playable, X1300 however experienced a few FPS drops at 10×7 and 12×10.

Overclocking and Conclusions

*Important update*

It has come to my attention that Tul does not carry a regular X1300 PRO. Instead it has its Bravo model with custom cooling device. The PRO model with golden heatsink you see on their product page does NOT exist.

What Tul is doing is they are providing customers with an OC BIOS. When you flash your regular PowerColor X1300 (400 MHz / 250 MHz) it will be clocked to PRO speeds (600 MHz / 400 MHz). This was exactly the card I have gotten — a non PRO flashed with PRO clockrates. What does that mean? Both PRO and non PRO models are equipped with the same type of memory, capable of 800 MHz DDR speeds. does NOT exist. Since I wasn’t aware of this fact, I assumed it was a PRO model based on the specifications on their website. The card I have received is indeed a retail product.

Our comparison is coming to an end. The last thing we need is to check how both cards overclock. As I mentioned on the previous pages both boards run their memory at maximum supported frequency — 700 MHz for X1600 XT and 400 MHz for X1300. As for core X1600 carries a 590 MHz burden. The little X1300 has been given a 600 MHz core at factory settings.

With maximum overclock I put those cards through a run of 3DMark05. There I looked for potential artifacts, anomalies and all the bad stuff that might happen as a result of over rated frequencies. As usual, I didn’t break anything (*knocks on wood*) but recorded final game test scores instead. Look above to get the results. So, the final verdict is as follows:

X1600 XT default: 590 MHz core / 700 MHz memory
X1600 XT OC: 640 MHz core / 770 MHz memory
X1300 PRO (modded) default: 600 MHz core / 400 MHz memory
X1300 PRO (modded) OC: 680 MHz core / 475 MHz memory

To give you an idea of how those results stack up I’ve prepared a little list of cards with default and OC values for your viewing pleasure. Best overclock so far is the X1800 XT.

Alright, it’s time for me to wrap everything up. While I can easily say both X1600 XT and X1300 from PowerColor are good products, I’m a bit famished. The performance of X1600 XT could be better yet I understand this might come in time with the new drivers. This XT as well as moddem PRO have it all; Avivo/HDTV along with H.264 decoding and transcoding, new Ultra-Threaded Shader Engine, Ring Bus memory controller (XT only) and most importantly Shader Model 3.0 support. RADEON X1600 doesn’t stay way behind the pack. As far as I’m concerned it’s performing properly for $200 bucks, but lacks that true 256-bit bus. The next gem, PowerColor X1300 is aimed at consumers with less money on hand or simply those who need advanced DirectX 9 support at a reasonable price / performance ratio. I cannot say anything bad about this particular product except it doesn’t come with a good bundle. An interesting thing to say is it has dual DVI ports. Most X1300’s don’t so that’s a plus for those with two LCD panels. Performance wise it gives a good run for the money (around $100 US dollars) and should satisfy the less-enthusiast crowd.
