GeForce RTX 3090 vs Radeon VII

Intro

Compare those specifications to the Radeon VII, which features GPU clock speed of 1400 MHz, and 16384 MB of HBM2 memory set to run at 1000 MHz through a 4096-bit bus. It also features 3840 Stream Processors, 240 Texture Address Units, 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

Theoretically speaking, the Radeon VII is 9% faster than the GeForce RTX 3090 in general, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce RTX 3090 should be a lot (more or less 36%) better at AF than the Radeon VII. (explain)

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

Pixel Rate

The GeForce RTX 3090 should be a lot (approximately 74%) faster with regards to full screen anti-aliasing than the Radeon VII, and also able to handle higher screen resolutions while still performing well. (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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at 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 card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 output 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 get to the max fill rate.
