In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 265 are marginally better than the AMD Radeon HD 7850 XFX Ultra OC Edition.

The HD 7850 has a 75 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon R7 265. This results in the HD 7850 providing 4.8 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 7850 has a 75 MHz higher core clock speed than the Radeon R7 265 and the same number of Render Output Units. This results in the HD 7850 providing 2.4 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 265 was released over a year more recently than the HD 7850, and so the Radeon R7 265 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7850.

The Radeon R7 265 has 1024 MB more video memory than the HD 7850, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Radeon R7 265 also has superior memory performance overall.

The Radeon R7 265 has 25.6 GB/sec greater memory bandwidth than the HD 7850, which means that the memory performance of the Radeon R7 265 is slightly better than the HD 7850.

Both the Radeon R7 265 and the Radeon HD 7850 XFX Ultra OC Edition have 1024 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 7850 has 4.8 GTexel/s better Texture Fill Rate and 2.4 GPixel/s better Pixel Fill Rate, but the Radeon R7 265 has 25.6 GB/sec greater memory bandwidth. Overall, the Radeon R7 265 has slightly better performance.

The Radeon R7 265 requires 150 Watts to run but there is no entry for the Radeon HD 7850 XFX Ultra OC Edition. We would recommend a PSU with at least 500 Watts for the Radeon R7 265 and a PSU with at least 500 Watts for the HD 7850. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewRadeon R7 265 is a fast-middle-class Graphics Card based on the Pitcairn PRO core of the Graphics Core Next Architecture.
The Pitcairn PRO Core is a GCN 1.0 Core and was previously used on Radeon HD 7850. It offers 1024 Shader Processing Units, 64 TMUs and 32 ROPs, on a 256-bit memory interface.
Compared to Radeon HD 7850, the central unit runs at 900 (instead of 860MHz) and goes up to 925MHz, in Turbo Mode, while the memory clock operates at 1400MHz (instead of 1200MHz). Due to the overclock, the rated TDP is considerably higher and of 150W.
In terms of performance, it stands between Radeon HD 7850 and Radeon HD 7870.
The release price of $150 is what makes this graphics card attractive, as there are no major changes from one card to another but rather a new cooling system and overclocking out of the box, already offered in modified Radeon HD 7850 versions.
Radeon HD 7850 XFX Ultra OC Edition is a special edition of the powerful Radeon HD 7850. See the standard version for more information about it.
The differences include an increase on the core-clock that went from 860MHz to 975MHz.
Benchmarks indicate a 7% boost when compared to the standard edition.
