Sapphire HD7790 2GB: Beefing up the Midrange Monster

Overview of the Sapphire HD7790 2GB


 The packaging for the HD7790 2GB is very similar to the 7790 we just recently viewed from Sapphire with the exception of the 2GB notation. The card is marked as overclocked and carries a 50MHz boost to the standard 1GHz clock. This is 25MHz below most other models so we will need to see how this affects performance vs previously tested models.



Here is a list of all items included in the accessory pack:

    • Installation Disc

    • Quick Start Guide/Manual
    • DVI to VGA Adapter
    • Crossfire Bridge
    • PATA 4 Pin connector to PCIe 6 pin adapter
    • HDMI Cable

The accessory package included is exactly like we saw from the previous 7790 from Sapphire. The eco-friendly packaging is cool as it shows environmentally consciousness of Sapphire as a company.

Here we have the full card and you can see that unlike the original 7790 we saw from Sapphire this one has a much larger centralized fan which pushes air in both front and rear sides to cool the full heatsink array.  Also do note the new backplate found on the 2GB models. We’ve always liked backplates as they cover sensitive components, stiffen the card and also make it look nice overall. This backplate happens to work as a heatsink as well and we will look more closely at this pretty soon.

The rear IO supports multiple connectivity options including:

  • DVI (x2)
  • HDMI
  • DisplayPort

This is connector array allows for the FleX functionality which allows for Dual DVI and HDMI displays in a 3 display array, this is nice and convenient as many displays simply do not have displayport.

Pulling the 2GB 7790 apart you can see for the most part it has a standard layout although the heatsink grid jutting up through the PCB was of interest. Upon removing the backplate you can see that there are thermal strips between the memory ICs and the backplate which allows the backplate to work as the heatsink for the memory and the small array comes through the PCB and into the cooling airflow from the GPU cooler which allows a form of active cooling for the rear memory ICs which means cooler and more  stable operation.

It is worth nothing that the card utilizes a single 6 pin PCIe connector for supplemental power which means the total board power would peak at about 150W (75W 6 pin & 75W PCIe Slot)  although I can bet this card never comes close to tapping that limit.


A closer Look at the HD7790

Digging in deeper here you have the HD7790 “Bonaire” GPU ready to unleash some serious gaming horsepower.

Here you can see the previously mentioned pass through on the PCB which allows the fin array from the backplate to reach the cooling airflow. This is a very cool design and we have to applaud Sapphire for this kind of innovation as it simply shows that they are very serious about making sure you have a great experience with their cards.

Here we see some of the power control circuitry built onto the card which will ensure solid and reliable operation. This may seem small when you compare to other cards we have looked at, but remember this mainstream GPU does not pull huge loads of power which means you don’t need a huge VRM setup to run or even overclock the card.

The Steam Deck – Valve delivers an excellent PC handheld

Valve is an interesting company that seems to try to be a lot of things at the same time. Games company, software hub/store and hardware company. Valve is all of these. When it comes to hardware the company has had mixed success. I think many of us remember the Steam Machines. These compact computers running SteamOS, a Linux based OS, were supposed to make Windows PC’s obsolete for gaming. They didn’t succeed. Valve also released a specific controller, the Steam Controller, which also did not exactly set the world on fire. In hindsight though both these products have paved the way for the product I am testing today, the Steam Deck, Valves attempt to compete with the Nintendo Switch in the handheld market.

Crucial P5 Plus 2TB

The Crucial P5 Plus is the successor the P5 that Crucial launched last year and is the first PCIe 4.0 NVMe SSD from the company. The latest model dropped the 256GB model, so the starting available capacity for the P5 Pro is 500GB. Additionally, the drive is also available in 1TB and a new storage capacity of 2TB model. The P54 Plus is priced similar to the P5 though there is a slight bump in the price where drive is retailed at $107.99(500GB), $179.99(1TB), and $367.99(2TB). The 2TB model is definitely a welcome addition and if we judge by the price per gigabyte, the 1TB model would be the most economical option. Despite the slight bump in the price, the P5 Plus are still priced competitively against its competitors. The question is, just how well would the performance backing it up? We shall find it out today.
