In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition are marginally better than the Nvidia GeForce GTX 465.

The HD 4890 has a 393 MHz higher core clock speed but 4 fewer Texture Mapping Units than the GeForce GTX 465. The lower TMU count doesn't matter, though, as altogether the HD 4890 manages to provide 13.3 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 4890 has a 393 MHz higher core clock speed than the GeForce GTX 465, but the GeForce GTX 465 has 16 more Render Output Units than the HD 4890. As a result, the GeForce GTX 465 exhibits a 3.4 GPixel/s better Pixel Fill Rate than the HD 4890. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GeForce GTX 465 was released less than a year after the HD 4890, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition and the GeForce GTX 465 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 4890 has 31.7 GB/sec greater memory bandwidth than the GeForce GTX 465, which means that the memory performance of the HD 4890 is noticeably better than the GeForce GTX 465.

The Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition has 800 Shader Processing Units and the GeForce GTX 465 has 352. However, the actual shader performance of the HD 4890 is 560 and the actual shader performance of the GeForce GTX 465 is 427. The HD 4890 having 133 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 4890 delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce GTX 465.

The GeForce GTX 465 transistor size technology is 15 nm (nanometers) smaller than the HD 4890. This means that the GeForce GTX 465 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4890. While they exhibit similar graphical performance, the GeForce GTX 465 should consume less power than the HD 4890.

The Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition requires 190 Watts to run and the GeForce GTX 465 requires 200 Watts. We would recommend a PSU with at least 500 Watts for the HD 4890 and a PSU with at least 550 Watts for the GeForce GTX 465. The GeForce GTX 465 requires 10 Watts more than the HD 4890 to run. The difference is not significant enough for the GeForce GTX 465 to have a noticeably larger impact on your yearly electricity bills than the HD 4890.

GPU Mini Review

Mini ReviewOverview
Radeon HD 4890 Sapphire Toxic Atomic 1GB Edition is a special edition of AMD's High-End Radeon HD 4890, created by Sapphire.

Overclock: Central Unit
The Central Unit now runs at 1000MHz, instead of 850MHz.

Overclock: Memory Clock
The Operating Memory Clock now runs at 1050MHz while the Frame Buffer remain the same.

Cooling Solution
The Cooling System has been replaced by Sapphire's Vapor-X Cooling Solution, which has cooling module on the GPU together with a heatsink and profiled fan venting heat out of the case.

Benchmarks indicate a 11% performance over the reference Radeon HD 4890.
GeForce GTX 465 is a high-end GPU based on the 40nm Fermi architecture.
It's based on the Fermi GF100 Core (optimized GF104 Core) and offers 352 Shader Processing Units, 42 TMUs and 32 ROPs, on 256-bit memory interface of fast GDDR5. The central unit runs at 607MHz and the memory clock operates at 802MHz.
Despite feature more Shader Processing Units than GeForce GTX 460, it's lower clocked. Benchmarks indicate that its performance is around 3% better than the standard version and therefore on level with GeForce GTX 460 v2.
Most modern demanding games will run at the highest settings using a 1080p resolution. However, some will require reduced settings to be played optimally.
