GeForce RTX 3080 12 GB vs Radeon VII

Intro

Compare those specs to the Radeon VII, which features 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 ROPs.

	Difference: 114278 (12%)

Texel Rate

The GeForce RTX 3080 12 GB is a bit (more or less 5%) faster with regards to texture filtering than the Radeon VII. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon VII		336000 Mtexels/sec
	Difference: 16800 (5%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 3080 12 GB is a better choice, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 51520 (58%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
