GeForce 8800 GT 512MB vs GeForce RTX 2080

Intro

Compare those specifications to the GeForce RTX 2080, which comes with GPU clock speed of 1515 MHz, and 8192 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also is made up of 2944 SPUs, 184 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB		105 Watts
GeForce RTX 2080		215 Watts
	Difference: 110 Watts (105%)

Memory Bandwidth

In theory, the GeForce RTX 2080 will be 696% faster than the GeForce 8800 GT 512MB in general, because of its higher bandwidth. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 401152 (696%)

Texel Rate

The GeForce RTX 2080 is quite a bit (more or less 730%) better at AF than the GeForce 8800 GT 512MB. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 245160 (730%)

Pixel Rate

The GeForce RTX 2080 should be much (more or less 910%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 512MB, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 87360 (910%)

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 information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 also depends on quite a few 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.
