In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6870 IceQ X Edition are significantly better than the Nvidia GeForce GTS 450 EVGA SuperClocked 1GB Edition.

The HD 6870 has a 18 MHz higher core clock speed and 24 more Texture Mapping Units than the GTS 450. This results in the HD 6870 providing 22.2 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 6870 has a 18 MHz higher core clock speed and 16 more Render Output Units than the GTS 450. This results in the HD 6870 providing 14.7 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 6870 was released less than a year after the GTS 450, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce GTS 450 EVGA SuperClocked 1GB Edition and the Radeon HD 6870 IceQ X 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 6870 has 73.6 GB/sec greater memory bandwidth than the GTS 450, which means that the memory performance of the HD 6870 is much better than the GTS 450.

The GeForce GTS 450 EVGA SuperClocked 1GB Edition has 192 Shader Processing Units and the Radeon HD 6870 IceQ X Edition has 1120. However, the actual shader performance of the GTS 450 is 339 and the actual shader performance of the HD 6870 is 504. The HD 6870 having 165 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6870 delivers a massively smoother and more efficient experience when processing graphical data than the GTS 450.

The GeForce GTS 450 EVGA SuperClocked 1GB Edition requires 107 Watts to run but there is no entry for the Radeon HD 6870 IceQ X Edition. We would recommend a PSU with at least 400 Watts for the GTS 450 and a PSU with at least 500 Watts for the HD 6870. The HD 6870 has been recommended a PSU with 100 Watts more than the GTS 450. The difference is significant enough that the HD 6870 may have an adverse affect on your yearly electricity bills in comparison to the GTS 450.

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 6870 IceQ X Edition is a special edition of the high-end Radeon HD 6870. See its page for more information about it.
Compared to the Radeon HD 6870, this Special Edition has exactly the same specifications and the only new feature is an improved cooling system which doesn't affect performance directly.
Therefore, the performance is EXACTLY like the standard Radeon HD 6870 and enough to run today's demanding games at maximum settings while Very Demanding games like Metro 2033 or Max Payne 3, will probably require reduced settings to run smoothly.
