GeForce RTX 3070 Ti vs GeForce RTX 3080

Intro

Compare those specifications to the GeForce RTX 3080, which comes with a clock frequency of 1440 MHz and a GDDR6X memory frequency of 1188 MHz. It also features a 320-bit memory bus, and makes use of a 8 nm design. It is comprised of 8704 SPUs, 272 Texture Address Units, and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3070 Ti		290 Watts
GeForce RTX 3080		320 Watts
	Difference: 30 Watts (10%)

Memory Bandwidth

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

GeForce RTX 3080		778547 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 155648 (25%)

Texel Rate

The GeForce RTX 3080 is quite a bit (about 30%) better at AF than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 3080		391680 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 89280 (30%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3070 Ti is superior to the GeForce RTX 3080, but not by far. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
GeForce RTX 3080		138240 Mpixels/sec
	Difference: 12960 (9%)

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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record 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 card's 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
