GeForce RTX 3070 Ti vs GeForce RTX 4080

Intro

Compare those specs to the GeForce RTX 4080, which makes use of a 4 nm design. nVidia has clocked the core speed at 2205 MHz. The GDDR6X memory runs at a speed of 1400 MHz on this model. It features 9728 SPUs along with 304 Texture Address Units and 112 ROPs.

GeForce RTX 3070 Ti		290 Watts
GeForce RTX 4080		320 Watts
	Difference: 30 Watts (10%)

Memory Bandwidth

Theoretically, the GeForce RTX 4080 should be a little bit faster than the GeForce RTX 3070 Ti overall. (explain)

GeForce RTX 4080		734003 MB/sec
GeForce RTX 3070 Ti		622899 MB/sec
	Difference: 111104 (18%)

Texel Rate

The GeForce RTX 4080 should be quite a bit (about 122%) more effective at AF than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 4080		670320 Mtexels/sec
GeForce RTX 3070 Ti		302400 Mtexels/sec
	Difference: 367920 (122%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 4080 is the winner, by a large margin. (explain)

GeForce RTX 4080		246960 Mpixels/sec
GeForce RTX 3070 Ti		151200 Mpixels/sec
	Difference: 95760 (63%)

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 largest amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
