GeForce RTX 3090 vs Radeon VII

Intro

The GeForce RTX 3090 features core speeds of 1395 MHz on the GPU, and 1219 MHz on the 24576 MB of GDDR6X RAM. It features 10496 SPUs as well as 328 Texture Address Units and 112 ROPs.

Compare all of that 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 speed of 1000 MHz on this model. It features 3840 SPUs along with 240 Texture Address Units 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

Theoretically speaking, the Radeon VII should be just 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 should be a lot (more or less 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 high levels of AA is important to you, then the GeForce RTX 3090 is superior to the Radeon VII, by a large margin. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card 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 applied per second.

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