GeForce RTX 3080 Ti vs Radeon VII

Intro

Compare all that to the Radeon VII, which has core clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 RAM. 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 should be a lot (more or less 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

The GeForce RTX 3080 Ti will be quite a bit (about 71%) faster with regards to AA than the Radeon VII, and also should be capable of handling higher screen resolutions better. (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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many 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.
