GeForce 8600 GTS vs GeForce RTX 2080

Intro

Compare those specifications to the GeForce RTX 2080, which features a clock frequency of 1515 MHz and a GDDR6 memory frequency of 1750 MHz. It also features a 256-bit memory bus, and uses a 12 nm design. It is comprised of 2944 SPUs, 184 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GTS		75 Watts
GeForce RTX 2080		215 Watts
	Difference: 140 Watts (187%)

Memory Bandwidth

Performance-wise, the GeForce RTX 2080 should in theory be quite a bit superior to the GeForce 8600 GTS in general. (explain)

GeForce RTX 2080		458752 MB/sec
GeForce 8600 GTS		32000 MB/sec
	Difference: 426752 (1334%)

Texel Rate

The GeForce RTX 2080 should be quite a bit (about 2481%) more effective at AF than the GeForce 8600 GTS. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce 8600 GTS		10800 Mtexels/sec
	Difference: 267960 (2481%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 is the winner, and very much so. (explain)

GeForce RTX 2080		96960 Mpixels/sec
GeForce 8600 GTS		5400 Mpixels/sec
	Difference: 91560 (1696%)

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 largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
