GeForce 8600 GT 512MB DDR2 vs Radeon HD 4350

Intro

The GeForce 8600 GT 512MB DDR2 has a core clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also uses a 128-bit memory bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specifications to the Radeon HD 4350, which has GPU core speed of 575 MHz, and 512 MB of DDR2 RAM set to run at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) Stream Processors, 8 TAUs, and 4 Raster Operation Units.

GeForce 8600 GT 512MB DDR2 12800 MB/sec
Radeon HD 4350 8000 MB/sec
Difference: 4800 (60%)

Texel Rate

The GeForce 8600 GT 512MB DDR2 should be quite a bit (about 88%) better at AF than the Radeon HD 4350. (explain)

GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Radeon HD 4350 4600 Mtexels/sec
Difference: 4040 (88%)

Pixel Rate

The GeForce 8600 GT 512MB DDR2 will be much (approximately 88%) faster with regards to full screen anti-aliasing than the Radeon HD 4350, and also should be capable of handling higher resolutions while still performing well. (explain)

GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Radeon HD 4350 2300 Mpixels/sec
Difference: 2020 (88%)

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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
