In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 670 DirectCU II OC Edition are massively better than the AMD Radeon HD 7770 Direct CU II TOP Edition.

The HD 7770 has a 140 MHz higher core clock speed than the GTX 670, but the GTX 670 has 72 more Texture Mapping Units than the HD 7770. As a result, the GTX 670 exhibits a 65 GTexel/s better Texture Fill Rate than the HD 7770. 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 140 MHz higher core clock speed than the GTX 670, but the GTX 670 has 16 more Render Output Units than the HD 7770. As a result, the GTX 670 exhibits a 13.5 GPixel/s better Pixel Fill Rate than the HD 7770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7770 was released less than a year after the GTX 670, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 670 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 GTX 670 also has superior memory performance overall.

The GTX 670 has 118.7 GB/sec greater memory bandwidth than the HD 7770, which means that the memory performance of the GTX 670 is massively better than the HD 7770.

The GeForce GTX 670 DirectCU II OC Edition has 1344 Shader Processing Units and the Radeon HD 7770 Direct CU II TOP Edition has 640. However, the actual shader performance of the GTX 670 is 1422 and the actual shader performance of the HD 7770 is 609. The GTX 670 having 813 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 670 delivers a massively smoother and more efficient experience when processing graphical data than the HD 7770.

GPU Mini Review

Mini ReviewGeForce GTX 670 DirectCU II OC Edition is a Special Edition of the powerful GeForce GTX 670. See the standard version for more information about it.
The new features include an increase in the core-clock that went from 915MHz to 980MHz while the Turbo Boost is now of 1058MHz. A 20% more effective cooler is also included.
The performance boost is significant and around 5% when compared to the standard GTX 670.
Most demanding games will run at the highest settings.
Radeon HD 7770 Direct CU II TOP 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 1150MHz and from 1000MHz to 1120MHz, respectively. A new cooling system, with two 8mm flatten copper heat-pipes is also available.
The performance boost is around 5%, when compared to the reference card and on level with Radeon HD 7770 Asus GHz Edition.
