Radeon R9 M375X vs Radeon RX 6900 XT

Intro

The Radeon R9 M375X has clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon RX 6900 XT, which has a clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 256-bit bus, and makes use of a 7 nm design. It features 5120 SPUs, 320 TAUs, and 128 ROPs.

Theoretically speaking, the Radeon RX 6900 XT is 628% quicker than the Radeon R9 M375X overall, due to its greater bandwidth. (explain)

Radeon RX 6900 XT 524288 MB/sec
Radeon R9 M375X 72000 MB/sec
Difference: 452288 (628%)

Texel Rate

The Radeon RX 6900 XT should be much (approximately 1338%) better at texture filtering than the Radeon R9 M375X. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Radeon R9 M375X 40600 Mtexels/sec
Difference: 543400 (1338%)

Pixel Rate

The Radeon RX 6900 XT will be much (approximately 1338%) faster with regards to AA than the Radeon R9 M375X, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
Radeon R9 M375X 16240 Mpixels/sec
Difference: 217360 (1338%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
