GeForce RTX 3070 vs GeForce RTX 3080 Ti

Intro

The GeForce RTX 3070 uses a 8 nm design. nVidia has clocked the core speed at 1500 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this model. It features 5888 SPUs as well as 184 TAUs and 96 Rasterization Operator Units.

Compare those specifications to the GeForce RTX 3080 Ti, which has a clock speed of 1365 MHz and a GDDR6X memory speed of 1188 MHz. It also features a 384-bit bus, and uses a 8 nm design. It features 10240 SPUs, 320 TAUs, and 112 ROPs.

Performance-wise, the GeForce RTX 3080 Ti should theoretically be a bit superior to 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 should be quite a bit (approximately 58%) more effective at AF 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 should be just a bit (approximately 6%) more effective at full screen anti-aliasing than the GeForce RTX 3070, and should be able to handle higher screen resolutions while still performing well. (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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
