Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 MSI PMD1 Edition are very slightly better than the AMD Radeon R7 250 2GB GDDR5.
The R7 250 and the HD 7770 have the same core clock speed of 1000 MHz, but the HD 7770 has 16 more Texture Mapping Units than the R7 250. As a result, the HD 7770 exhibits a 16 GTexel/s better Texture Fill Rate than the R7 250. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.
The R7 250 and the HD 7770 have the same core clock speed of 1000 MHz, but the HD 7770 has 8 more Render Output Units than the R7 250. As a result, the HD 7770 exhibits a 8 GPixel/s better Pixel Fill Rate than the R7 250. 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.
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. This is supported by the fact that the R7 250 also has superior memory performance overall.
The R7 250 has 1.6 GB/sec greater memory bandwidth than the HD 7770, which means that the memory performance of the R7 250 is marginally better than the HD 7770.
The Radeon R7 250 2GB GDDR5 has 384 Shader Processing Units and the Radeon HD 7770 MSI PMD1 Edition has 640. However, the actual shader performance of the R7 250 is 345.6 and the actual shader performance of the HD 7770 is 576. The HD 7770 having 230.4 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7770 delivers a slightly smoother and more efficient experience when processing graphical data than the R7 250.
The Radeon R7 250 2GB GDDR5 requires 65 Watts to run and the Radeon HD 7770 MSI PMD1 Edition requires 150 Watts. We would recommend a PSU with at least 400 Watts for the R7 250 and a PSU with at least 500 Watts for the HD 7770. The HD 7770 requires 85 Watts more than the R7 250 to run. The difference is significant enough that the HD 7770 may have an adverse affect on your yearly electricity bills in comparison to the R7 250.

|Mini Review||Radeon R7 250 is a middle-class graphics card based on the GCN architecture. |
It packs a core codenamed Oland XT, previously used on Radeon HD 8670 (OEM). Therefore, it offers 384 Shader Processing Units, 24 TMUs and 8 ROPs, on a 128-bit bus width of fast GDDR5. While the central unit runs at 1000MHz and goes up to 1050MHz, in Turbo Mode, the memory clock operates at 1150MHz.
Its performance is somewhat comparable to Radeon HD 7750, though the latter will perform better at DirectX 11 games.
Please note that are also DDR3 variants which are significantly slower and that this GDDR5 version should come in 1GB and 2GB versions, though both will offer the same performance.
|Radeon HD 7770 MSI PMD1 Edition is a special edition of the fast-middle-class Radeon HD 7770 that features a cooling system with Propeller Blade technology which offers 20% more airflow than traditional fan design, according to MSI and has no changes that affects its performance directly. |
Therefore, its performance is on level with the reference card.
