GeForce 8600 GT 256MB GDDR3 vs Radeon HD 3690/3830

Intro

The GeForce 8600 GT 256MB GDDR3 makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 RAM is set to run at a speed of 700 MHz on this particular model. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare those specifications to the Radeon HD 3690/3830, which has core clock speeds of 668 MHz on the GPU, and 828 MHz on the 256 MB of GDDR3 RAM. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

The Radeon HD 3690/3830 is much (approximately 24%) more effective at anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)

Radeon HD 3690/3830 10688 Mtexels/sec
GeForce 8600 GT 256MB GDDR3 8640 Mtexels/sec
Difference: 2048 (24%)

Pixel Rate

The Radeon HD 3690/3830 will be quite a bit (approximately 147%) more effective at AA than the GeForce 8600 GT 256MB GDDR3, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon HD 3690/3830 10688 Mpixels/sec
GeForce 8600 GT 256MB GDDR3 4320 Mpixels/sec
Difference: 6368 (147%)

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 max amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of 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.
