In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 560 Asus DirectCU II TOP 1GB Edition are noticeably better than the AMD Radeon HD 7770 Sapphire GHz OC Edition.

The HD 7770 has a 225 MHz higher core clock speed than the GTX 560, but the GTX 560 has 16 more Texture Mapping Units than the HD 7770. As a result, the GTX 560 exhibits a 5.8 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 225 MHz higher core clock speed than the GTX 560, but the GTX 560 has 16 more Render Output Units than the HD 7770. As a result, the GTX 560 exhibits a 11.2 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 560, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTX 560 Asus DirectCU II TOP 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 GTX 560 has 54.4 GB/sec greater memory bandwidth than the HD 7770, which means that the memory performance of the GTX 560 is much better than the HD 7770.

The GeForce GTX 560 Asus DirectCU II TOP 1GB Edition has 336 Shader Processing Units and the Radeon HD 7770 Sapphire GHz OC Edition has 640. However, the actual shader performance of the GTX 560 is 622 and the actual shader performance of the HD 7770 is 626. The HD 7770 having 4 better shader performance is not particularly notable, as altogether the GTX 560 performs better when taking into account other relevant data.

The HD 7770 transistor size technology is 12 nm (nanometers) smaller than the GTX 560. This means that the HD 7770 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 560.

The GeForce GTX 560 Asus DirectCU II TOP 1GB Edition requires 150 Watts to run and the Radeon HD 7770 Sapphire GHz OC Edition requires 80 Watts. We would recommend a PSU with at least 450 Watts for the GTX 560 and a PSU with at least 450 Watts for the HD 7770. The GTX 560 requires 70 Watts more than the HD 7770 to run. The difference is significant enough that the GTX 560 may have an adverse affect on your yearly electricity bills in comparison to the HD 7770.

GPU Mini Review

Mini ReviewOverview
GeForce GTX 560 Asus DirectCU II TOP 1GB Edition is a Special Edition of NVIDIA's Performance GeForce GTX 560, created by Asus.

Overclock: Central Unit
The Central Unit now runs at 925MHz, instead of 810MHz.

Overclock: Memory Clock
The Operating Memory Clock is now of 1050MHz, instead of 1002MHz.

Frame Buffer
Untouched.


Cooling Solution
DirectCU II: Copper heat pipes in direct contact with the GPU to speed up heat dissipation for over 20% cooler performance, DirectCU II takes cooling further with twin 80mm fans for doubled airflow.

Performance
Benchmarks Indicate a 9% Performance Boost over the Reference GeForce GTX 560.
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).
