Radeon RX 580 vs Radeon VII

Intro

Compare those specs to the Radeon VII, which has a GPU core clock speed of 1400 MHz, and 16384 MB of HBM2 RAM set to run at 1000 MHz through a 4096-bit bus. It also is comprised of 3840 SPUs, 240 Texture Address Units, and 64 Raster Operation Units.

Memory Bandwidth

In theory, the Radeon VII should be 300% quicker than the Radeon RX 580 in general, due to its greater bandwidth. (explain)

Radeon VII		1048576 MB/sec
Radeon RX 580		262144 MB/sec
	Difference: 786432 (300%)

Texel Rate

The Radeon VII is a lot (more or less 86%) more effective at AF than the Radeon RX 580. (explain)

Radeon VII		336000 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 154992 (86%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon VII is the winner, and very much so. (explain)

Radeon VII		89600 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 49376 (123%)

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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 maximum fill rate.
