GeForce GTX 1070 vs GeForce RTX 2080 SUPER

Intro

Compare those specifications to the GeForce RTX 2080 SUPER, which uses a 12 nm design. nVidia has clocked the core frequency at 1650 MHz. The GDDR6 memory runs at a frequency of 1937 MHz on this particular model. It features 3072 SPUs along with 192 TAUs and 64 Rasterization Operator 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

Theoretically speaking, the GeForce RTX 2080 SUPER should perform much faster than 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 will be quite a bit (about 75%) faster with regards to 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

If running with high levels of AA is important to you, then the GeForce RTX 2080 SUPER is a better choice, not by a very large margin though. (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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock 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 memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of 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.
