GeForce GTX 1070 vs GeForce RTX 3080 Ti

Intro

Compare all of that to the GeForce RTX 3080 Ti, which comes with a core clock speed of 1365 MHz and a GDDR6X memory speed of 1188 MHz. It also makes use of a 384-bit memory bus, and makes use of a 8 nm design. It is made up of 10240 SPUs, 320 Texture Address Units, and 112 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070		150 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 200 Watts (133%)

Memory Bandwidth

In theory, the GeForce RTX 3080 Ti should be 256% quicker than the GeForce GTX 1070 overall, because of its greater bandwidth. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce GTX 1070		262144 MB/sec
	Difference: 672153 (256%)

Texel Rate

The GeForce RTX 3080 Ti should be a lot (about 142%) faster with regards to texture filtering than the GeForce GTX 1070. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 256080 (142%)

Pixel Rate

The GeForce RTX 3080 Ti should be quite a bit (more or less 59%) better at anti-aliasing than the GeForce GTX 1070, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce GTX 1070		96384 Mpixels/sec
	Difference: 56496 (59%)

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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
