GeForce RTX 3080 Ti vs Radeon VII

Intro

The GeForce RTX 3080 Ti makes use of a 8 nm design. nVidia has set the core speed at 1365 MHz. The GDDR6X RAM runs at a frequency of 1188 MHz on this specific card. It features 10240 SPUs as well as 320 TAUs and 112 Rasterization Operator Units.

Compare those specifications to the Radeon VII, which features clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 RAM. It features 3840 SPUs as well as 240 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon VII 295 Watts
GeForce RTX 3080 Ti 350 Watts
Difference: 55 Watts (19%)

Memory Bandwidth

As far as performance goes, the Radeon VII should in theory be just a bit superior to the GeForce RTX 3080 Ti in general. (explain)

Radeon VII 1048576 MB/sec
GeForce RTX 3080 Ti 934297 MB/sec
Difference: 114279 (12%)

Texel Rate

The GeForce RTX 3080 Ti is quite a bit (about 30%) more effective at anisotropic filtering than the Radeon VII. (explain)

GeForce RTX 3080 Ti 436800 Mtexels/sec
Radeon VII 336000 Mtexels/sec
Difference: 100800 (30%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 3080 Ti is a better choice, by a large margin. (explain)

GeForce RTX 3080 Ti 152880 Mpixels/sec
Radeon VII 89600 Mpixels/sec
Difference: 63280 (71%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated 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 write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
