GeForce RTX 3080 12 GB vs Radeon VII

Intro

Compare all that to the Radeon VII, which uses a 7 nm design. AMD has clocked the core speed at 1400 MHz. The HBM2 memory runs at a frequency of 1000 MHz on this specific card. It features 3840 SPUs along with 240 TAUs and 64 Rasterization Operator Units.

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

Theoretically speaking, the Radeon VII should be 12% faster than the GeForce RTX 3080 12 GB in general, because of its higher data rate. (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 should be a small bit (about 5%) better at 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
