In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 Vapor-X GHz OC Edition are significantly better than the AMD Radeon R7 250 v2 2GB.

The HD 7770 has a 100 MHz higher core clock speed and 16 more Texture Mapping Units than the R7 250. This results in the HD 7770 providing 20 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 100 MHz higher core clock speed and 8 more Render Output Units than the R7 250. This results in the HD 7770 providing 9.6 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 R7 250 was released over a year more recently than the HD 7770, and so the R7 250 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 R7 250 has 1024 MB more video memory than the HD 7770, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the HD 7770 has superior memory performance.

The HD 7770 has 54.4 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the HD 7770 is much better than the R7 250.

The Radeon HD 7770 Vapor-X GHz OC Edition has 640 Shader Processing Units and the Radeon R7 250 v2 2GB has 384. However, the actual shader performance of the HD 7770 is 598 and the actual shader performance of the R7 250 is 343. The HD 7770 having 255 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7770 delivers a significantly smoother and more efficient experience when processing graphical data than the R7 250.

The Radeon R7 250 v2 2GB requires 65 Watts to run but there is no entry for the HD 7770. We would recommend a PSU with at least 400 Watts for the R7 250, but we do not have a recommended PSU wattage for the HD 7770.

GPU Mini Review

Mini ReviewRadeon HD 7770 Vapor-X GHz OC Edition is a special edition of the fast-middle-class Radeon HD 7770. See the standard version for more information about it.
The differences include increased memory and core clocks, from 1125MHz to 1300MHz and from 1000MHz to 1100MHz, respectively. A new quiet and efficient cooling system, called Vapor-X, is also available.
Benchmarks indicate a 8% performance boost when compared to the standard Radeon HD 7770.
Benchmarks indicate that the most demanding games (e.g. Metro 2033) still require reduced settings to be played smoothly.
Note: This Graphics Card has 2 variants: one with DDR3 and another with GDDR5. This is the DDR3 Version.

Radeon R7 250 v2 2GB offers a GCN 1.1 Core codenamed Oland PRO and thus features 384 Shader Processing Units, 24 TMUs and 8 ROPs, on a 128-bit bus width of standard DDR3. While the central unit runs at 1000MHz and goes up to 1050MHz, in Turbo Mode, the memory clock operates at 900MHz.
With a rated board TDP of 65W, it requires no extra power connectors.

Its performance is up to 10% lower than the original Radeon R7 250 which is equipped with fast GDDR5. However, at lower resolutions, both cards offer similar performance. It's worth mentioning that even an integrated Radeon R7 7850K offers better performance.
