GeForce 8600 GT 512MB DDR2 vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which features a core clock frequency of 1700 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It features 3840 SPUs, 240 Texture Address Units, and 96 Raster Operation Units.

Theoretically speaking, the Radeon RX 6800 should be 3996% faster than the GeForce 8600 GT 512MB DDR2 overall, due to its greater bandwidth. (explain)

Radeon RX 6800		524288 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 511488 (3996%)

Texel Rate

The Radeon RX 6800 should be a lot (about 4622%) better at AF than the GeForce 8600 GT 512MB DDR2. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 399360 (4622%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 is the winner, by a large margin. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 158880 (3678%)

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 (measured in megabytes per second) that can be moved over 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 RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
