GeForce RTX 3080 Ti vs Radeon VII

Intro

Compare all of that to the Radeon VII, which comes with a clock frequency of 1400 MHz and a HBM2 memory speed of 1000 MHz. It also makes use of a 4096-bit bus, and uses a 7 nm design. It is made up of 3840 SPUs, 240 Texture Address Units, and 64 Raster Operation Units.

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

The Radeon VII should in theory be a bit faster 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 should be much (approximately 30%) faster with regards to AF than the Radeon VII. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3080 Ti is a better choice, and very much so. (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 max amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If 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 amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
