GeForce RTX 3080 vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which features core clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 RAM. It features 3840 SPUs as well as 240 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon VII		295 Watts
GeForce RTX 3080		320 Watts
	Difference: 25 Watts (8%)

Memory Bandwidth

The Radeon VII should theoretically perform much faster than the GeForce RTX 3080 in general. (explain)

Radeon VII		1048576 MB/sec
GeForce RTX 3080		778547 MB/sec
	Difference: 270029 (35%)

Texel Rate

The GeForce RTX 3080 will be just a bit (about 17%) more effective at anisotropic filtering than the Radeon VII. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon VII		336000 Mtexels/sec
	Difference: 55680 (17%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3080 is a better choice, by a large margin. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 48640 (54%)

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 (counted in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
