GeForce RTX 3080 Ti vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which uses a 7 nm design. AMD has set the core frequency at 1400 MHz. The HBM2 RAM runs at a frequency of 1000 MHz on this specific model. It features 3840 SPUs along with 240 Texture Address Units 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

In theory, the Radeon VII should be just a bit faster than the GeForce RTX 3080 Ti overall. (explain)

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

Texel Rate

The GeForce RTX 3080 Ti is a lot (about 30%) better at AF than the Radeon VII. (explain)

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

Pixel Rate

The GeForce RTX 3080 Ti will be quite a bit (about 71%) more effective at AA than the Radeon VII, and also will be capable of handling higher resolutions without slowing down too much. (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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 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 higher this number, the better the graphics 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 that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 max fill rate.
