In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6600 GT are significantly better than the Nvidia GeForce 8300 GS.

The GeForce 8300 GS was released over a year more recently than the GeForce 6600 GT, and so the GeForce 8300 GS 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 GeForce 8300 GS has 384 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 2.4 GB/sec greater memory bandwidth than the GeForce 8300 GS, which means that the memory performance of the GeForce 6600 GT is marginally better than the GeForce 8300 GS.

The GeForce 8300 GS has 8 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the GeForce 8300 GS is 9 and the actual shader performance of the GeForce 6600 GT is 6. The GeForce 8300 GS having 3 better shader performance is not particularly notable, as altogether the GeForce 6600 GT performs better when taking into account other relevant data.

The GeForce 8300 GS requires 40 Watts to run and the GeForce 6600 GT requires 48 Watts. We would recommend a PSU with at least 300 Watts for the GeForce 8300 GS. The GeForce 6600 GT requires 8 Watts more than the GeForce 8300 GS 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 GeForce 8300 GS.

GPU Mini Review

Mini ReviewThe GeForce 8 Series, a computer graphics processing unit, is the eighth generation of NVIDIA's GeForce line. The third major GPU architecture developed at NVIDIA, the GeForce 8 represents the company's first unified shader architecture. It competed primarily against ATI's Radeon HD 2000-series cards.
There has been, at times, controversy over the naming of GeForce 8 series chips, including due to previous-generation chips being repackaged with minor changes (or possibly none at all) with the new names implying they are derived from the newly-introduced GPU chip design featured by the flagship products.
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.
