GeForce 8500 GT vs GeForce RTX 2080 Ti

Intro

Compare that to the GeForce RTX 2080 Ti, which comes with clock speeds of 1350 MHz on the GPU, and 1750 MHz on the 11264 MB of GDDR6 RAM. It features 4352 SPUs along with 272 Texture Address Units and 88 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8500 GT		45 Watts
GeForce RTX 2080 Ti		250 Watts
	Difference: 205 Watts (456%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 Ti should in theory be quite a bit better than the GeForce 8500 GT overall. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 617984 (4828%)

Texel Rate

The GeForce RTX 2080 Ti is a lot (approximately 10100%) better at AF than the GeForce 8500 GT. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 363600 (10100%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 Ti is a better choice, by far. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 117000 (6500%)

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 maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
