GeForce 8600 GT 512MB DDR2 vs Radeon RX 6800 XT

Intro

Compare those specifications to the Radeon RX 6800 XT, which has GPU clock speed of 1825 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 4608 SPUs, 288 TAUs, and 128 ROPs.

GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 511488 (3996%)

Texel Rate

The Radeon RX 6800 XT will be much (approximately 5983%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 516960 (5983%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6800 XT is the winner, by far. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 229280 (5307%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
