GeForce 8800 GT 512MB vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which has a GPU core clock speed of 1650 MHz, and 8192 MB of GDDR6 memory running at 1937 MHz through a 256-bit bus. It also is made up of 3072 SPUs, 192 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB		105 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 145 Watts (138%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should be 782% faster than the GeForce 8800 GT 512MB in general, due to its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 450304 (782%)

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (more or less 843%) more effective at texture filtering than the GeForce 8800 GT 512MB. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 283200 (843%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is a better choice, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 96000 (1000%)

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 megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
