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.

The GTX 670 has a 130 MHz higher core clock speed and 72 more Texture Mapping Units than the Radeon HD 4890. This results in the GTX 670 providing 75.8 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 GTX 670 has a 130 MHz higher core clock speed and 16 more Render Output Units than the Radeon HD 4890. This results in the GTX 670 providing 17.8 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 three years more recently than the Radeon HD 4890, and so the GTX 670 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the Radeon HD 4890 when running the latest games.

The GTX 670 has 1024 MB more video memory than the Radeon 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 67.5 GB/sec greater memory bandwidth than the Radeon HD 4890, which means that the memory performance of the GTX 670 is much better than the Radeon HD 4890.

The GeForce GTX 670 DirectCU II OC Edition has 1344 Shader Processing Units and the Radeon HD 4890 has 800. However, the actual shader performance of the GTX 670 is 1422 and the actual shader performance of the Radeon HD 4890 is 476. The GTX 670 having 946 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 Radeon HD 4890.

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

The Radeon HD 4890 requires 190 Watts to run but there is no entry for the GTX 670. We would recommend a PSU with at least 500 Watts for the Radeon HD 4890, but we do not have a recommended PSU wattage for the GTX 670.

GPU Mini Review

Mini ReviewGeForce 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.
Radeon HD 4890 is a High-End Graphics Card based on the R700 Architecture.

R700 was AMD's Second Unified Shader Architecture.

It equips a GPU Codenamed RV790 XT which has 10 Compute Units activated and thus offers 800 Shader Processing Units, 40 TMUs and 16 ROPs. The Central Unit is clocked at 850MHz.

The GPU accesses a 1GB frame buffer of GDDR3, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 975MHz.

DirectX 10.1 Support (10.0 Hardware Default) and support for Crossfire.

Power Consumption
With a rated board TDP of 190W, it requires at least a 500W PSU and at least 2 available 6-pin connetors.

Gaming benchmarks put its performance on average with a more recent GeForce GTX 460 meaning is it considerably faster than Radeon HD 4870.
