Sapphire Nitro R9 390 8G DS Review, Playing With Nitro

Temperatures, Noise, Power, & Overclocking

Power Consumption

Power

We take power consumption at the wall using a Kill A Watt Power drain measurement device, I loaded Unigine Heaven and let it idle for 30 minutes recorded the Idle temperature and Power Consumption, shut it down and let it cool for a half hour then repeated the test twice in this sequence, For the load I ran Unigine Heaven looping for 30 minutes, let it cool down to the Idle temps established in the previous test then looped it 30 minutes repeating the process a total of 3 times. Once completed I take the three results from each test and average them giving me an aggregate  average for each result. Killing two birds with one stone and getting Power Consumption and Thermals.

Power

With a Faster core and faster memory we expected the Sapphire Nitro R9 390 to pull a few more watts from the wall and at idle we hit 87W and load took us to 353W.

Temperatures

Temps

For Thermal readings I load and run Unigine Heaven for 30 minutes then read the thermal load, Cool the machine down for 30 minutes at an idle then read the Idle temperatures. I repeat that same process three times then average the three runs and report those scores. An eye is kept out for anomalous runs, if an anomaly occurs I shut the machine down let it cool off, reboot and rerun the test.

Thermal_Idle

At an idle the Sapphire Nitro R9 390 did pretty well and ran at a comfy 32°C. The Tri-X cooling is working impressively at keeping the Sapphire Nitro R9 390 cool.

Thermal_Load

At load we got an impressive 68°C which is an amazing result for any R9 390.

Noise

New Noise

We all hate noisy or whiny fans that intrude on our gaming / computing time. We run several noise level tests, Complete Idle, spiking load where the graphics load fluctuates between high and low load, and high load. We generally record sound levels sitting next to the tower with the tower at floor shelf level. We put the decibel meter close to where our ear would be and take measurements from there.  To better get an idea of what the sound compares to here is a scale of typical sound levels.

Typical
Sound Levels

Jet takeoff (200 feet)120 dBA
Construction Site110 dBA
Shout (5 feet)100 dBA
Heavy truck (50 feet) 90 dBA
Urban street 80 dBA
Automobile interior 70 dBA
Normal conversation (3 feet) 60 dBA
Office, classroom 50 dBA
Living room 40 dBA
Bedroom at night 30 dBA
Broadcast studio 20 dBA
Rustling leaves 10 dBA

We aren’t really known for running a quiet test rig and you push the CPU to full usage overclocked to 4.4GHz and you get some noise with our setup.

Noise_1

We averaged around 60dBA with the Sapphire Nitro R9 390 but we would suspect that most of that was Radiator and system fan cooling. The best way for us to put it is that we were happy with the quiet operation of the Sapphire Nitro R9 390 and HExzilla is getting transformed to a triple Radiator shortly to quieten the beast down a little.

Overclocking

OCing

Here’s the stock GPU-Z Shot showing the core is primed to run at a 10MHz factory OC and memory running at 1500MHz real 6000MHz effective. GPU-Z hasn’t caught up with the Grenada renaming so it sees it as a Hawaii GPU but since it plainly states it’s an R9 390 we know that it’s a Grenada core and DirectX 12 ready.

GPU-Z_Stock

Our Stock shot of GPU-Z shows that everything is in order and we have a true R9 390 but like most utilities GPU-Z is still reading it as a Hawaii Core and since it’s an R9 390 it sports the Grenada core.

GPU-Z_1175_Core

Here’s our best stable OC which is darn good for an R9 390 and we hit 1175 on the core and 1740 on the memory. This isn’t one of those pretty we didn’t benchmark it shots, this is an entirely stable benchable and playable OC.

FireStrike

Here’s one of out Stock Clock FireStrike runs and GPU score hits 12147 on stock clocks s lets take a look at the OC’d score.

FireStrike_1175_Core_1740_Memory

With our sweet OC we got a graphics score of 13983 considerably better than the stock score of 12147 so lets look at it on a chart.

Firestrike_OC

Our 13983 boosted the Sapphire Nitro R9 390 ahead of the Asus Strix R9 390x by just a couple of points, like 662 points higher so that’s a pretty sweet OC. Of course OC the Strix to the max and it would take back the lead but at stock clocks it got beat by a R9 390.

  1. Thanks for the review but what is up with 3 flavors of 960 but not a single 970 to compare it with? The 970 is what it is priced against, not the 960 or the 980. Just seems a little odd to me.

  2. Did you have to adjust the voltage to maintain that overclock?

    • Yes to maintain the 1175MHz OC the voltage had to be increased to almost the max. That’s a top end OC pushing the GPU to the limit and we wouldn’t recommend that for a 24/7 OC. Back that down a bit until voltages start to drop then hold there.

      • Just an update, .. I just picked up the new Sapphire Nitro r9 390 w/ backplate – and have got a stable 1100 / 1625 with no voltage increase. The fans are dead quite, and temps remain low – impressive!

  3. So I just got an the MSI r9 390 and have noticed that Battlefield 4 crashes on Ultra settings (1920×1200). Looked it up and it’s a problem with anti aliasing being turned on. Turned it off and it runs fine. That being said, I don’t want to turn it off. Would anyone here know if this could be a problem with the voltage and if I need to change that?

    • Update your sound, Video and chipset drivers by downloading them from the vendors website and make sure you have all the latest drivers. The Sapphire R9 390 8G played Battlefield at both 1920 x 1080 and 1920 x 1200 and didn’t crash. As far as it goes we can’t provide support on the MSI card or any other card for that matter. Support for your problem should be addressed to MSI and their support team who have their own support team. Usually it’s a old driver issue on one of your motherboard components or a compromised game file. So update all drivers and reinstall the game short of that get with MSI support.

      • Thanks for the response! I’ll try that out. For what it’s worth, I made a post on the amd forum and haven’t gotten a response, but I’ll try with MSI, too.

  4. Are you really not going to answer the “why no 970” question? I’d like to know too…

    • Perhaps if you formed a complete thought and organized a complete “Why no 970” question we could answer it. If it’s a why is there no 970 on the charts in a particular review then chances are a different reviewer got it. If it’s a why no 970 purchase choice, sure spend 50 – 70 bucks more and get one if you like they are a good card. If it’s a why do you prefer AMD we don’t we love video cards in general. It’s a simple fact that a video card takes a week or two to review correctly, as does a motherboard so not every component can be covered.
