GeForce RTX 3070 vs GeForce RTX 3080 Ti

Intro

Compare those specifications to the GeForce RTX 3080 Ti, which uses a 8 nm design. nVidia has set the core frequency at 1365 MHz. The GDDR6X memory works at a speed of 1188 MHz on this particular card. It features 10240 SPUs as well as 320 Texture Address Units and 112 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070		220 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 130 Watts (59%)

Memory Bandwidth

Theoretically, the GeForce RTX 3080 Ti should perform a little bit faster than the GeForce RTX 3070 overall. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
GeForce RTX 3070		(Unknown) MB/sec
	Difference: 934297 (-100%)

Texel Rate

The GeForce RTX 3080 Ti will be a lot (about 58%) better at anisotropic filtering than the GeForce RTX 3070. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
GeForce RTX 3070		276000 Mtexels/sec
	Difference: 160800 (58%)

Pixel Rate

The GeForce RTX 3080 Ti will be a little bit (more or less 6%) faster with regards to AA than the GeForce RTX 3070, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
GeForce RTX 3070		144000 Mpixels/sec
	Difference: 8880 (6%)

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 data (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 the card's 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
