GeForce GTX 460 vs GeForce RTX 2080 SUPER

Intro

Compare all that to the GeForce RTX 2080 SUPER, which has a GPU core clock speed of 1650 MHz, and 8192 MB of GDDR6 memory running at 1937 MHz through a 256-bit bus. It also is made up of 3072 Stream Processors, 192 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460		150 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should be 488% faster than the GeForce GTX 460 in general, because of its greater data rate. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 421504 (488%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (approximately 738%) more effective at anisotropic filtering than the GeForce GTX 460. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 279000 (738%)

Pixel Rate

The GeForce RTX 2080 SUPER will be quite a bit (more or less 552%) better at full screen anti-aliasing than the GeForce GTX 460, and will be capable of handling higher resolutions while still performing well. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 89400 (552%)

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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
