GeForce 8600 GT 512MB DDR2 vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this particular model. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 512MB DDR2		47 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 253 Watts (538%)

Memory Bandwidth

In theory, the Radeon RX 6900 XT should be 3996% quicker than the GeForce 8600 GT 512MB DDR2 in general, because of its greater bandwidth. (explain)

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 (about 6659%) more effective 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 running with a high resolution is important to you, then the Radeon RX 6900 XT is a better choice, by far. (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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
