In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7770 Sapphire GHz OC Edition are significantly better than the Nvidia GeForce GTS 450 EVGA SuperClocked 1GB Edition.

The HD 7770 has a 268 MHz higher core clock speed and 8 more Texture Mapping Units than the GTS 450. This results in the HD 7770 providing 17.8 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 7770 has a 268 MHz higher core clock speed than the GTS 450 and the same number of Render Output Units. This results in the HD 7770 providing 4.3 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 HD 7770 was released over a year more recently than the GTS 450, and so the HD 7770 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTS 450.

The GeForce GTS 450 EVGA SuperClocked 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 19.2 GB/sec greater memory bandwidth than the GTS 450, which means that the memory performance of the HD 7770 is slightly better than the GTS 450.

The GeForce GTS 450 EVGA SuperClocked 1GB Edition has 192 Shader Processing Units and the Radeon HD 7770 Sapphire GHz OC Edition has 640. However, the actual shader performance of the GTS 450 is 339 and the actual shader performance of the HD 7770 is 626. The HD 7770 having 287 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 GTS 450.

The HD 7770 transistor size technology is 12 nm (nanometers) smaller than the GTS 450. This means that the HD 7770 is expected to run slightly cooler and achieve higher clock frequencies than the GTS 450.

The GeForce GTS 450 EVGA SuperClocked 1GB Edition requires 107 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 GTS 450 and a PSU with at least 450 Watts for the HD 7770. The GTS 450 requires 27 Watts more than the HD 7770 to run. The difference is not significant enough for the GTS 450 to have a noticeably larger impact on your yearly electricity bills than the HD 7770.

GPU Mini Review

Mini ReviewOverview
GeForce GTS 450 EVGA Superclocked 1GB Edition is a special edition of NVIDIA's fast-middle-class GeForce GTS 450, created by EVGA.

Overclock Out of The Box
The Central Unit is now of 882MHz, instead of 783MHz while the Operating Memory Clock was increased to 950MHz.

Cooling Solution
The Cooling System was replaced by EVGA's Single Fan Solution which means the Graphics Card runs cooler under load.

Performance
Benchmarks indicate a 10% performance boost over the reference GeForce GTS 450.
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).
