GeForce 8800 GTX vs GeForce RTX 2080

Intro

Compare those specs to the GeForce RTX 2080, which has core clock speeds of 1515 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 2944 SPUs along with 184 Texture Address Units and 64 ROPs.

GeForce 8800 GTX		86400 MB/sec
	Difference: 372352 (431%)

Texel Rate

The GeForce RTX 2080 is quite a bit (more or less 658%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 241960 (658%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2080 is superior to the GeForce 8800 GTX, by a large margin. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 83160 (603%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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.
