GeForce 8600 GT 512MB DDR2 vs Radeon HD 4790

Intro

The GeForce 8600 GT 512MB DDR2 comes with core clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

Compare all of that to the Radeon HD 4790, which makes use of a 55 nm design. AMD has clocked the core speed at 600 MHz. The GDDR5 memory works at a speed of 800 MHz on this specific card. It features 640(128x5) SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 4790 should be quite a bit faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)

Radeon HD 4790 102400 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 89600 (700%)

Texel Rate

The Radeon HD 4790 is much (more or less 122%) more effective at AF than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon HD 4790 19200 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 10560 (122%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 4790 is the winner, by a large margin. (explain)

Radeon HD 4790 9600 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 5280 (122%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
