GeForce GTX 460 1GB vs GeForce RTX 2080 SUPER

Intro

Compare all of that to the GeForce RTX 2080 SUPER, which makes use of a 12 nm design. nVidia has set the core frequency at 1650 MHz. The GDDR6 memory runs at a frequency of 1937 MHz on this particular card. It features 3072 SPUs as well as 192 TAUs and 64 Rasterization Operator Units.

GeForce GTX 460 1GB		160 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

Theoretically, the GeForce RTX 2080 SUPER should perform much faster than the GeForce GTX 460 1GB overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 460 1GB		115200 MB/sec
	Difference: 392704 (341%)

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (about 738%) more effective at AF than the GeForce GTX 460 1GB. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 279000 (738%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2080 SUPER is a better choice, by a large margin. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 460 1GB		21600 Mpixels/sec
	Difference: 84000 (389%)

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 (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface 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 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
