GeForce RTX 3080 12 GB vs Radeon VII

Intro

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

GeForce RTX 3080 12 GB		934298 MB/sec
	Difference: 114278 (12%)

Texel Rate

The GeForce RTX 3080 12 GB will be a little bit (about 5%) more effective at anisotropic 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 using a high resolution is important to you, then the GeForce RTX 3080 12 GB is superior to the Radeon VII, 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 megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling 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 its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
