In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 2GB GHz Edition are marginally better than the AMD Radeon R7 250X.

The HD 7770 has a 50 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon R7 250X. This results in the HD 7770 providing 2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7770 has a 50 MHz higher core clock speed than the Radeon R7 250X and the same number of Render Output Units. This results in the HD 7770 providing 0.8 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon R7 250X was released over a year more recently than the HD 7770, and so the Radeon R7 250X is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7770.

The Radeon R7 250X and the Radeon HD 7770 2GB GHz Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the Radeon R7 250X and the Radeon HD 7770 2GB GHz Edition are the same, which means the Radeon R7 250X and the HD 7770 have equal limitations when it comes to graphical data transfer.

Both the Radeon R7 250X and the Radeon HD 7770 2GB GHz Edition have 640 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the HD 7770 has 2 GTexel/s better Texture Fill Rate and 0.8 GPixel/s better Pixel Fill Rate, but the has GB/sec greater memory bandwidth. Although the GPUs are very similar in performance, the HD 7770 takes the edge.

The Radeon R7 250X requires 80 Watts to run and the Radeon HD 7770 2GB GHz Edition requires 80 Watts. We would recommend a PSU with at least 450 Watts for the Radeon R7 250X and a PSU with at least 500 Watts for the HD 7770. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon R7 250X is a fast-middle-class Graphics Card based on the Graphics Core Next architecture. It offers the Cape Verde XT GPU.
The Cape Verde XT Core is a GCN 1.1 GPU and was first seen on Radeon HD 7770 and then re-used in the OEM only Radeon HD 8760.
It offers 640 Shader Processing Units, 40 TMUs and 16 ROPs, on a 128-bits memory interface of fast GDDR5.
Radeon R7 250X comes clocked at 950MHz (though there might be some 1GHz versions) and has its operating memory clock set at 1125MHz. The rated TDP board is of 80W and the release price around $99.
This card should come in 1GB and 2GB versions, though both will offer the same performance.
Its performance has proven to be exactly like Radeon HD 7770 GHz Edition (if clocked at 1GHz) and thus this card is not suited for 1080p gaming but it can handle 720p with ease. The 950MHz versions will be around 3% slower.
Radeon HD 7770 2GB GHz Edition is a variant of the Radeon HD 7770 GHz Edition aka just Radeon HD 7770.
The only difference between this version and the original is the increase in the video memory that was doubled from 1GB to 2GB.
It's proved that extra memory for this GPU does not yield extra performance. Therefore, this GPU's performance is exactly like the standards.
