GeForce GTX 1070 vs GeForce RTX 2080 SUPER

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070		150 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 SUPER should in theory be a lot superior to the GeForce GTX 1070 overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 1070		262144 MB/sec
	Difference: 245760 (94%)

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (approximately 75%) more effective at anisotropic filtering than the GeForce GTX 1070. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is superior to the GeForce GTX 1070, but not by far. (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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 are processed in one second. This figure is worked out by multiplying the total number of texture units 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 most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
