GeForce RTX 3080 Ti vs Radeon VII

Intro

Compare those specs to the Radeon VII, which comes with a core clock speed of 1400 MHz and a HBM2 memory speed of 1000 MHz. It also features a 4096-bit memory bus, and makes use of a 7 nm design. It features 3840 SPUs, 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

In theory, the Radeon VII should be a little 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 is a lot (approximately 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

The GeForce RTX 3080 Ti is much (about 71%) better at AA than the Radeon VII, and also should be able to handle higher screen resolutions while still performing well. (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 data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 max fill rate.
