GeForce 8800 GS vs GeForce RTX 2080

Intro

Compare all that to the GeForce RTX 2080, which comes with a clock frequency of 1515 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It features 2944 SPUs, 184 Texture Address Units, and 64 ROPs.

GeForce 8800 GS		26400 Mtexels/sec
	Difference: 252360 (956%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 is superior to the GeForce 8800 GS, and very much so. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 90360 (1369%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
