In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 6670 v2 MSI 2GB Edition are significantly better than the Nvidia GeForce 8600 GTS 256MB.

The HD 6670 has a 125 MHz higher core clock speed and 8 more Texture Mapping Units than the 8600 GTS. This results in the HD 6670 providing 8.4 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 HD 6670 has a 125 MHz higher core clock speed than the 8600 GTS and the same number of Render Output Units. This results in the HD 6670 providing 1 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 HD 6670 was released over three years more recently than the 8600 GTS, and so the HD 6670 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8600 GTS when running the latest games.

The HD 6670 has 1792 MB more video memory than the 8600 GTS, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the 8600 GTS has superior memory performance.

The 8600 GTS has 10.7 GB/sec greater memory bandwidth than the HD 6670, which means that the memory performance of the 8600 GTS is slightly better than the HD 6670.

The Radeon HD 6670 v2 MSI 2GB Edition has 480 Shader Processing Units and the GeForce 8600 GTS 256MB has 32. However, the actual shader performance of the HD 6670 is 192 and the actual shader performance of the 8600 GTS is 54. The HD 6670 having 138 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 6670 delivers a marginally smoother and more efficient experience when processing graphical data than the 8600 GTS.

The HD 6670 transistor size technology is 40 nm (nanometers) smaller than the 8600 GTS. This means that the HD 6670 is expected to run much cooler and achieve higher clock frequencies than the 8600 GTS.

The Radeon HD 6670 v2 MSI 2GB Edition requires 66 Watts to run and the GeForce 8600 GTS 256MB requires 75 Watts. We would recommend a PSU with at least 400 Watts for the HD 6670 and a PSU with at least 350 Watts for the 8600 GTS. The 8600 GTS requires 9 Watts more than the HD 6670 to run. The difference is not significant enough for the 8600 GTS to have a noticeably larger impact on your yearly electricity bills than the HD 6670.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6670 v2 MSI 2GB Edition is a special edition of AMD's fast-middle-class Radeon HD 6670 v2, created by MSI.

Overclock: Central Unit
The Central Unit runs at the same speed.

Overclock: Memory Clock
The Operating Memory Clock runs at 667MHz and the Frame Buffer was raised to 2GB. This is a gimmick and in no way benefits the GPU.

Cooling Solution
The Cooling System remains the same.

Without Overclocking Out of The Box, Radeon HD 6670 v2 MSI 2GB Edition is as fast as the reference Radeon HD 6670 v2.
GeForce 8600 GTS is a fast-middle-class GFX based on the 80nm variant of the first-shader unified architecture.
It's based on the G84 Core and offers 32 Shader Processing Units, 16 TMUs and 8 ROPs, on a 128-bit memory interface of GDDR3. The central unit runs at 675MHz and the memory clock operates 1000MHz. It will consume no more than 75 Watt.
It's therefore a further clocked GeForce 8600 GT and should be significantly faster.
This GPU is only suited for a 1024x768 (or less) resolution. Today's games will run at medium settings although extremely demanding games might not run at all. DirectX 11 based games aren't supported and its performance will decrease drastically, as the resolution increases.
