GeForce 8600 GT 1GB GDDR3 22400 MB/sec
Difference: 3200 (14%)

Texel Rate

The GeForce 8600 GT 1GB GDDR3 should be a lot (about 49%) faster with regards to anisotropic filtering than the Radeon HD 3650 256MB. (explain)

GeForce 8600 GT 1GB GDDR3 8640 Mtexels/sec
Radeon HD 3650 256MB 5800 Mtexels/sec
Difference: 2840 (49%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8600 GT 1GB GDDR3 is superior to the Radeon HD 3650 256MB, by a large margin. (explain)

GeForce 8600 GT 1GB GDDR3 4320 Mpixels/sec
Radeon HD 3650 256MB 2900 Mpixels/sec
Difference: 1420 (49%)

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: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 get to the max fill rate.
