GeForce RTX 3090 vs Radeon VII

Intro

Compare that to the Radeon VII, which features GPU core speed of 1400 MHz, and 16384 MB of HBM2 memory set to run at 1000 MHz through a 4096-bit bus. It also is comprised of 3840 SPUs, 240 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon VII		295 Watts
GeForce RTX 3090		350 Watts
	Difference: 55 Watts (19%)

Memory Bandwidth

The Radeon VII, in theory, should be a bit faster than the GeForce RTX 3090 in general. (explain)

Radeon VII		1048576 MB/sec
GeForce RTX 3090		958668 MB/sec
	Difference: 89908 (9%)

Texel Rate

The GeForce RTX 3090 is much (approximately 36%) more effective at anisotropic filtering than the Radeon VII. (explain)

GeForce RTX 3090		457560 Mtexels/sec
Radeon VII		336000 Mtexels/sec
	Difference: 121560 (36%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3090 is a better choice, by far. (explain)

GeForce RTX 3090		156240 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 66640 (74%)

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 transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
