In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are significantly better than the AMD Radeon HD 5450 Gigabyte OC 512MB Edition.

The HD 5450 has a 160 MHz higher core clock speed than the 8600 GT, but the 8600 GT has 8 more Texture Mapping Units than the HD 5450. As a result, the 8600 GT exhibits a 3 GTexel/s better Texture Fill Rate than the HD 5450. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 5450 has a 160 MHz higher core clock speed than the 8600 GT, but the 8600 GT has 4 more Render Output Units than the HD 5450. As a result, the 8600 GT exhibits a 1.5 GPixel/s better Pixel Fill Rate than the HD 5450. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 5450 was released over three years more recently than the 8600 GT, and so the HD 5450 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8600 GT when running the latest games.

The Radeon HD 5450 Gigabyte OC 512MB Edition and the GeForce 8600 GT 512MB GDDR3 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The 8600 GT has 9.6 GB/sec greater memory bandwidth than the HD 5450, which means that the memory performance of the 8600 GT is marginally better than the HD 5450.

The Radeon HD 5450 Gigabyte OC 512MB Edition has 80 Shader Processing Units and the GeForce 8600 GT 512MB GDDR3 has 32. However, the actual shader performance of the HD 5450 is 56 and the actual shader performance of the 8600 GT is 43. The HD 5450 having 13 better shader performance is not particularly notable, as altogether the 8600 GT performs better when taking into account other relevant data.

The HD 5450 transistor size technology is 40 nm (nanometers) smaller than the 8600 GT. This means that the HD 5450 is expected to run much cooler and achieve higher clock frequencies than the 8600 GT.

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run but there is no entry for the HD 5450. We would recommend a PSU with at least 400 Watts for the HD 5450 and a PSU with at least 350 Watts for the 8600 GT. The HD 5450 has been recommended a PSU with 50 Watts more than the 8600 GT. The difference is significant enough that the HD 5450 may have a slight adverse affect on your yearly electricity bills in comparison to the 8600 GT.

GPU Mini Review

Mini ReviewRadeon HD 5450 Gigabyte OC 512MB Edition is a special edition of the entry-level Radeon HD 5450.
This edition comes overclocked out of the box in the core-clock which went from 650MHz to 700MHz.
Expect an up to 5% performance boost in most games, when compared to the reference card.
GeForce 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.
