In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 Sapphire GHz OC Edition are significantly better than the AMD Radeon R7 250 HIS iCooler 1GB Edition.

The HD 7770 has a 150 MHz higher core clock speed and 16 more Texture Mapping Units than the R7 250. This results in the HD 7770 providing 22 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 150 MHz higher core clock speed and 8 more Render Output Units than the R7 250. This results in the HD 7770 providing 10.4 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 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 Radeon R7 250 HIS iCooler 1GB Edition and the Radeon HD 7770 Sapphire GHz OC Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7770 has 6.4 GB/sec greater memory bandwidth than the R7 250, which means that the memory performance of the HD 7770 is marginally better than the R7 250.

The Radeon R7 250 HIS iCooler 1GB Edition has 384 Shader Processing Units and the Radeon HD 7770 Sapphire GHz OC Edition has 640. However, the actual shader performance of the R7 250 is 343 and the actual shader performance of the HD 7770 is 626. The HD 7770 having 283 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7770 delivers a noticeably smoother and more efficient experience when processing graphical data than the R7 250.

The Radeon R7 250 HIS iCooler 1GB Edition requires 65 Watts to run and the Radeon HD 7770 Sapphire GHz OC Edition requires 80 Watts. We would recommend a PSU with at least 400 Watts for the R7 250 and a PSU with at least 450 Watts for the HD 7770. The HD 7770 requires 15 Watts more than the R7 250 to run. The difference is not significant enough for the HD 7770 to have a noticeably larger impact on your yearly electricity bills than the R7 250.

GPU Mini Review

Mini ReviewOverview
Radeon R7 250 HIS iCooler 1GB Edition is a special edition of AMD's fast-middle-class Radeon R7 250 1GB, created by HIS.

Overclock Out of The Box
The Clock Frequencies of both Central Unit and Operating Memory Clock Remain the Same.

Cooling Solution
The card is equipped with iCooler, making it extremely quiet and noise level is less than 28dB. Additionally, it is now Single-Slot.

Performance
Without Overclocking Out of The Box, Radeon R7 250 HIS iCooler 1GB Edition is as fast as the reference Radeon R7 250 1GB.
Radeon HD 7770 Sapphire 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 1250MHz and from 1000MHz to 1150MHz, respectively. A new quiet and efficient cooling system is also available.
Benchmarks indicate a 9,5% performance boost when compared to the standard Radeon HD 7770.
Benchmarks indicate that the most demanding games (e.g. Metro 2033) will run at the highest settings but not at extreme resolutions (due to the limited memory size).
