GeForce 8500 GT vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which uses a 12 nm design. nVidia has set the core speed at 1650 MHz. The GDDR6 memory is set to run at a frequency of 1937 MHz on this particular card. It features 3072 SPUs as well as 192 TAUs and 64 ROPs.

GeForce 8500 GT		12800 MB/sec
	Difference: 495104 (3868%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (about 8700%) better at anisotropic filtering than the GeForce 8500 GT. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 313200 (8700%)

Pixel Rate

The GeForce RTX 2080 SUPER will be quite a bit (approximately 5767%) better at FSAA than the GeForce 8500 GT, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 103800 (5767%)

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 (counted in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
