GeForce 8800 GT 512MB vs Radeon RX 6900 XT

Intro

The GeForce 8800 GT 512MB features a clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 ROPs.

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

The Radeon RX 6900 XT will be much (more or less 1638%) more effective at texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 550400 (1638%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is superior to the GeForce 8800 GT 512MB, by a large margin. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
GeForce 8800 GT 512MB 9600 Mpixels/sec
Difference: 224000 (2333%)

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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core 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 applied per 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. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many 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.
