GeForce RTX 3070 Ti vs GeForce RTX 4080

Intro

Compare all that 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 is set to run at a speed of 1400 MHz on this specific card. It features 9728 SPUs as well as 304 TAUs and 112 ROPs.

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

Texel Rate

The GeForce RTX 4080 should be quite a bit (approximately 122%) faster with regards to texture filtering 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 running with a high screen resolution is important to you, then the GeForce RTX 4080 is superior to the GeForce RTX 3070 Ti, 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
