GeForce 8600 GT 512MB DDR2 vs Radeon RX 6700 XT

Intro

The GeForce 8600 GT 512MB DDR2 has a GPU clock speed of 540 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon RX 6700 XT, which comes with GPU core speed of 2321 MHz, and (Unknown) MB of GDDR6 RAM set to run at 2000 MHz through a 192-bit bus. It also is comprised of 2560 Stream Processors, 160 TAUs, and 64 Raster Operation Units.

Radeon RX 6700 XT 393216 MB/sec
GeForce 8600 GT 512MB DDR2 12800 MB/sec
Difference: 380416 (2972%)

Texel Rate

The Radeon RX 6700 XT should be quite a bit (more or less 4198%) better at AF than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6700 XT 371360 Mtexels/sec
GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Difference: 362720 (4198%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6700 XT is the winner, by a large margin. (explain)

Radeon RX 6700 XT 148544 Mpixels/sec
GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Difference: 144224 (3339%)

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 information (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 potential to get to the maximum fill rate.
