GeForce 8800 GT 512MB vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which has GPU clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM set to run at 1750 MHz through a 256-bit bus. It also is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

GeForce 8800 GT 512MB		105 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 120 Watts (114%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT should be 696% faster than the GeForce 8800 GT 512MB overall, due to its greater data rate. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 401152 (696%)

Texel Rate

The Radeon RX 5700 XT will be much (more or less 664%) better at AF than the GeForce 8800 GT 512MB. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 223200 (664%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5700 XT is a better choice, by a large margin. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 93120 (970%)

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 maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 rate is also dependant on lots of 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.
