GeForce RTX 3080 Ti vs Radeon VII

Intro

Compare all that to the Radeon VII, which has core clock speeds of 1400 MHz on the GPU, and 1000 MHz on the 16384 MB of HBM2 memory. It features 3840 SPUs along with 240 TAUs and 64 ROPs.

GeForce RTX 3080 Ti		934297 MB/sec
	Difference: 114279 (12%)

Texel Rate

The GeForce RTX 3080 Ti will be quite a bit (approximately 30%) faster with regards to texture filtering than the Radeon VII. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon VII		336000 Mtexels/sec
	Difference: 100800 (30%)

Pixel Rate

The GeForce RTX 3080 Ti will be quite a bit (about 71%) faster with regards to full screen anti-aliasing than the Radeon VII, and should be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon VII		89600 Mpixels/sec
	Difference: 63280 (71%)

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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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