In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6600 GT are significantly better than the AMD Radeon HD 2400 Pro.

The HD 2400 was released over a year more recently than the GeForce 6600 GT, and so the HD 2400 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6600 GT.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The HD 2400 has 128 MB more video memory than the GeForce 6600 GT, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the GeForce 6600 GT has superior memory performance.

The GeForce 6600 GT has 8.8 GB/sec greater memory bandwidth than the HD 2400, which means that the memory performance of the GeForce 6600 GT is marginally better than the HD 2400.

The Radeon HD 2400 Pro has 40 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the HD 2400 is 21 and the actual shader performance of the GeForce 6600 GT is 6. The HD 2400 having 15 better shader performance is not particularly notable, as altogether the GeForce 6600 GT performs better when taking into account other relevant data.

The Radeon HD 2400 Pro requires 20 Watts to run and the GeForce 6600 GT requires 48 Watts. We would recommend a PSU with at least 300 Watts for the HD 2400. The GeForce 6600 GT requires 28 Watts more than the HD 2400 to run. The difference is not significant enough for the GeForce 6600 GT to have a noticeably larger impact on your yearly electricity bills than the HD 2400.

GPU Mini Review

Mini ReviewRadeon HD 2400 Pro is an entry-level GPU based on the 65nm variant of the second unified shader architecture, R600.
It's based on the RV610 Core and offers 40 Shader Processing Units, 4 TMUs and 4 ROPs a 64-bit memory interface of standard DDR2. The central unit runs at 525MHz and the memory clock runs at up to 400MHz. It's therefore a higher clocked Radeon HD 2350 Pro and should only be somewhat faster.
Today's games only playable at unattractive resolutions and using low (most likely) or medium (maybe) presets. Its performance, is however, quite superior to the integrated Radeon HD 2100. DirectX 11 games aren't supported.
Supercharge your gaming with the power of an NVIDIA GeForce 6600 GPU. The NVIDIA GeForce 6600 GPUs deliver best-in-class performance and advanced visual effects for next-generation games. The only GPU in its class with support for Microsoft DirectX 9.0 Shader Model 3.0 and with support for PCI Express, the GeForce 6600 delivers ultra-realistic effects, unmatched features, and rock-solid stability so you can play your game the way itís meant to be played.
