GeForce 8600 GT 512MB DDR2 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 memory runs at a frequency of 2000 MHz on this particular card. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Radeon RX 6900 XT		524288 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 511488 (3996%)

Texel Rate

The Radeon RX 6900 XT is much (more or less 6659%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 575360 (6659%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is the winner, and very much so. (explain)

Radeon RX 6900 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
