GeForce 8800 GT 512MB vs Radeon RX 7900 XT

Intro

Compare all of that to the Radeon RX 7900 XT, which has core speeds of 1500 MHz on the GPU, and 2500 MHz on the 20480 MB of GDDR6 memory. It features 5376 SPUs along with 336 Texture Address Units and 192 Rasterization Operator Units.

The Radeon RX 7900 XT will be a lot (approximately 1400%) better at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 470400 (1400%)

Pixel Rate

The Radeon RX 7900 XT should be much (more or less 2900%) better at anti-aliasing than the GeForce 8800 GT 512MB, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 278400 (2900%)

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 (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
