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

Performance-wise, the Radeon VII should in theory be just a bit better than 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 texture filtering than the Radeon VII. (explain)

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

Pixel Rate

If using a high resolution 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 max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card 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 that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
