In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4650 1GB are significantly better than the Nvidia GeForce 8600 GT 512MB GDDR3.

The HD 4650 has a 60 MHz higher core clock speed and 16 more Texture Mapping Units than the 8600 GT. This results in the HD 4650 providing 10.6 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 4650 has a 60 MHz higher core clock speed than the 8600 GT and the same number of Render Output Units. This results in the HD 4650 providing 0.5 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 4650 was released over a year more recently than the 8600 GT, and so the HD 4650 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 8600 GT.

The HD 4650 has 512 MB more video memory than the 8600 GT, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The memory bandwidth of the GeForce 8600 GT 512MB GDDR3 and the Radeon HD 4650 1GB are the same, which means the 8600 GT and the HD 4650 have equal limitations when it comes to graphical data transfer.

The GeForce 8600 GT 512MB GDDR3 has 32 Shader Processing Units and the Radeon HD 4650 1GB has 320. However, the actual shader performance of the 8600 GT is 43 and the actual shader performance of the HD 4650 is 134. The HD 4650 having 91 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 4650 delivers a marginally smoother and more efficient experience when processing graphical data than the 8600 GT.

The HD 4650 transistor size technology is 25 nm (nanometers) smaller than the 8600 GT. This means that the HD 4650 is expected to run slightly cooler and achieve higher clock frequencies than the 8600 GT.

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run and the Radeon HD 4650 1GB requires 48 Watts. We would recommend a PSU with at least 350 Watts for the 8600 GT and a PSU with at least 400 Watts for the HD 4650. The HD 4650 requires 2 Watts more than the 8600 GT to run. The difference is not significant enough for the HD 4650 to have a noticeably larger impact on your yearly electricity bills than the 8600 GT.

GPU Mini Review

Mini ReviewGeForce 8600 GT 512MB GDDR3 is one of the many variants of the fast-middle-class GeForce 8600 GT.
On this version, the GPU is equipped with 512MB of standard GDDR3. The architecture allows the use of 512MB, since the GPU's processing power is strong enough and the memory controller is up for the task of processing 512MB. Therefore, the performance is superior to the 256MB version and any other version of DDR2, including 1GB.
However, and due to its architecture limitations, modern demanding games will require reduced settings, even if they don't require more than 512MB of video ram. Very Demanding games like Metro 2033 are only playable at the lowest settings.
Loaded with the latest features, ATI Radeon� HD 4600 Series graphics cards deliver a level of gaming performance previously only found in high-end graphics cards. Redefine the way you play HD games and enjoy unprecedented levels of graphics realism powered by 320 stream processing units, up to 1GB of memory and support for Microsoft DirectX� 10.1 games. Upgrade your graphics card and watch Blu-ray movies and play HD content with incredible visual fidelity. These graphics cards do it all with break-through energy efficiency, eliminating the need for an external power connection and making them easy to install.
