GeForce RTX 3070 Ti vs GeForce RTX 3080 Ti

Intro

The GeForce RTX 3070 Ti has core speeds of 1575 MHz on the GPU, and 1188 MHz on the 8192 MB of GDDR6X RAM. It features 6144 SPUs as well as 192 Texture Address Units and 96 ROPs.

Compare all of that to the GeForce RTX 3080 Ti, which makes use of a 8 nm design. nVidia has clocked the core frequency at 1365 MHz. The GDDR6X memory is set to run at a speed of 1188 MHz on this particular card. It features 10240 SPUs as well as 320 TAUs and 112 ROPs.

GeForce RTX 3080 Ti 934297 MB/sec
GeForce RTX 3070 Ti 622899 MB/sec
Difference: 311398 (50%)

Texel Rate

The GeForce RTX 3080 Ti will be a lot (more or less 44%) faster with regards to texture filtering than the GeForce RTX 3070 Ti. (explain)

GeForce RTX 3080 Ti 436800 Mtexels/sec
GeForce RTX 3070 Ti 302400 Mtexels/sec
Difference: 134400 (44%)

Pixel Rate

The GeForce RTX 3080 Ti should be a bit (more or less 1%) faster with regards to full screen anti-aliasing than the GeForce RTX 3070 Ti, and also will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 3080 Ti 152880 Mpixels/sec
GeForce RTX 3070 Ti 151200 Mpixels/sec
Difference: 1680 (1%)

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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
