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 4890 Sapphire Vapor-X OC 1GB Edition.

The GTX 670 has a 110 MHz higher core clock speed and 72 more Texture Mapping Units than the HD 4890. This results in the GTX 670 providing 75 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 GTX 670 has a 110 MHz higher core clock speed and 16 more Render Output Units than the HD 4890. This results in the GTX 670 providing 17.5 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 GTX 670 was released over a year more recently than the HD 4890, and so the GTX 670 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 4890.

The GTX 670 has 1024 MB more video memory than the HD 4890, 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 57.9 GB/sec greater memory bandwidth than the HD 4890, which means that the memory performance of the GTX 670 is much better than the HD 4890.

The Radeon HD 4890 Sapphire Vapor-X OC 1GB Edition has 800 Shader Processing Units and the GeForce GTX 670 DirectCU II OC Edition has 1344. However, the actual shader performance of the HD 4890 is 487 and the actual shader performance of the GTX 670 is 1422. The GTX 670 having 935 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 4890.

The GTX 670 transistor size technology is 27 nm (nanometers) smaller than the HD 4890. This means that the GTX 670 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4890.

The Radeon HD 4890 Sapphire Vapor-X OC 1GB Edition requires 190 Watts to run but there is no entry for the GeForce GTX 670 DirectCU II OC Edition. We would recommend a PSU with at least 500 Watts for the HD 4890.

GPU Mini Review

Mini ReviewOverview
Radeon HD 4890 Sapphire Vapor-X OC 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 870MHz, 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.

Performance
Benchmarks indicate a 3% performance over the reference Radeon HD 4890.
GeForce 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.
