GeForce GTX 465 vs GeForce RTX 2080 SUPER

Intro

Compare all of that to the GeForce RTX 2080 SUPER, which comes with a core clock frequency of 1650 MHz and a GDDR6 memory frequency of 1937 MHz. It also features a 256-bit memory bus, and makes use of a 12 nm design. It features 3072 SPUs, 192 TAUs, and 64 ROPs.

GeForce GTX 465		102592 MB/sec
	Difference: 405312 (395%)

Texel Rate

The GeForce RTX 2080 SUPER is a lot (more or less 1086%) better at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 290092 (1086%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 86176 (444%)

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 data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
