GeForce RTX 2080 vs GeForce RTX 4070 Ti

Intro

Compare all that to the GeForce RTX 4070 Ti, which has core clock speeds of 2310 MHz on the GPU, and 1313 MHz on the 12288 MB of GDDR6X RAM. It features 7680 SPUs as well as 240 TAUs and 80 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080		215 Watts
GeForce RTX 4070 Ti		285 Watts
	Difference: 70 Watts (33%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 4070 Ti should perform just a bit faster than the GeForce RTX 2080 overall. (explain)

GeForce RTX 4070 Ti		516096 MB/sec
GeForce RTX 2080		458752 MB/sec
	Difference: 57344 (13%)

Texel Rate

The GeForce RTX 4070 Ti will be quite a bit (approximately 99%) better at AF than the GeForce RTX 2080. (explain)

GeForce RTX 4070 Ti		554400 Mtexels/sec
GeForce RTX 2080		278760 Mtexels/sec
	Difference: 275640 (99%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 4070 Ti is superior to the GeForce RTX 2080, and very much so. (explain)

GeForce RTX 4070 Ti		184800 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 87840 (91%)

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 information (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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