GeForce RTX 3080 12 GB vs Radeon R9 M375X

Intro

Compare those specs to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 312200 (769%)

Pixel Rate

The GeForce RTX 3080 12 GB should be quite a bit (more or less 769%) faster with regards to full screen anti-aliasing than the Radeon R9 M375X, and also should be able to handle higher resolutions better. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 124880 (769%)

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 (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
