In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7790 DirectCU II OC 2GB Edition are significantly better than the Nvidia GeForce 9800 GTX SLI.

The HD 7790 has a 400 MHz higher core clock speed than the 9800 GTX, but the 9800 GTX has 56 more Texture Mapping Units than the HD 7790. As a result, the 9800 GTX exhibits a 15.4 GTexel/s better Texture Fill Rate than the HD 7790. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7790 has a 400 MHz higher core clock speed than the 9800 GTX, but the 9800 GTX has 16 more Render Output Units than the HD 7790. As a result, the 9800 GTX exhibits a 4.4 GPixel/s better Pixel Fill Rate than the HD 7790. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7790 was released over three years more recently than the 9800 GTX, and so the HD 7790 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 9800 GTX when running the latest games.

The HD 7790 has 1024 MB more video memory than the 9800 GTX, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7790 also has superior memory performance overall.

The 9800 GTX has 38.4 GB/sec greater memory bandwidth than the HD 7790, which means that the memory performance of the 9800 GTX is noticeably better than the HD 7790.

The GeForce 9800 GTX SLI has 128 Shader Processing Units and the Radeon HD 7790 DirectCU II OC 2GB Edition has 896. However, the actual shader performance of the 9800 GTX is 86 and the actual shader performance of the HD 7790 is 963. The HD 7790 having 877 better shader performance is not particularly notable, as altogether the 9800 GTX performs better when taking into account other relevant data.

The HD 7790 transistor size technology is 37 nm (nanometers) smaller than the 9800 GTX. This means that the HD 7790 is expected to run much cooler and achieve higher clock frequencies than the 9800 GTX.

The GeForce 9800 GTX SLI requires 280 Watts to run but there is no entry for the Radeon HD 7790 DirectCU II OC 2GB Edition. We would recommend a PSU with at least 600 Watts for the 9800 GTX.

GPU Mini Review

Mini ReviewThe SLI setup of GeForce 9800 GTX.Radeon HD 7790 DirectCU II OC 2GB Edition is a special edition of the performance Radeon HD 7790.
This edition comes with a cooling solution called DirectCU II, which achieves 20% lower temps and vastly quieter performance than reference with direct-contact copper heatpipes and dual fans, according to Asus. It also comes overclocked out of the box in the core-clock to 1075MHz and on the memory clock to 1600MHz, though the latter might prove useless, as this card might not benefit from extra bandwidth.
The 2GB framer buffer proves useless and Benchmarks indicate a 5% performance boost when compared to the reference card.
