GeForce RTX 3080 12 GB vs Radeon VII

Intro

Compare those specs to the Radeon VII, which makes use of a 7 nm design. AMD has clocked the core speed at 1400 MHz. The HBM2 memory works at a frequency of 1000 MHz on this specific card. It features 3840 SPUs as well as 240 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon VII		295 Watts
GeForce RTX 3080 12 GB		350 Watts
	Difference: 55 Watts (19%)

Memory Bandwidth

In theory, the Radeon VII should be a bit faster than the GeForce RTX 3080 12 GB in general. (explain)

Radeon VII		1048576 MB/sec
GeForce RTX 3080 12 GB		934298 MB/sec
	Difference: 114278 (12%)

Texel Rate

The GeForce RTX 3080 12 GB is just a bit (approximately 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 using high levels of AA 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 information (measured in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
