GeForce GTX 1070 vs GeForce RTX 2080 SUPER

Intro

Compare all of that to the GeForce RTX 2080 SUPER, which features a core clock speed of 1650 MHz and a GDDR6 memory frequency of 1937 MHz. It also uses a 256-bit memory bus, and makes use of a 12 nm design. It is made up of 3072 SPUs, 192 TAUs, and 64 Raster Operation Units.

GeForce GTX 1070		262144 MB/sec
	Difference: 245760 (94%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (more or less 75%) better at AF than the GeForce GTX 1070. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 136080 (75%)

Pixel Rate

The GeForce RTX 2080 SUPER will be a small bit (approximately 10%) faster with regards to AA than the GeForce GTX 1070, and also able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 1070		96384 Mpixels/sec
	Difference: 9216 (10%)

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 (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This number is calculated 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 graphics 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 maximum amount of pixels that the graphics chip 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 the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
