GeForce RTX 3090 vs Radeon VII

Intro

Compare those specs to the Radeon VII, which uses a 7 nm design. AMD has clocked the core frequency at 1400 MHz. The HBM2 memory is set to run at a frequency of 1000 MHz on this specific model. It features 3840 SPUs along with 240 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the Radeon VII should in theory be a little bit superior to the GeForce RTX 3090 overall. (explain)

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

Texel Rate

The GeForce RTX 3090 should be much (more or less 36%) faster with regards to anisotropic filtering 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 will be a lot (approximately 74%) better at FSAA than the Radeon VII, and also able to handle higher resolutions better. (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 data (measured in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This figure 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
