Radeon R9 M375 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which comes with a core clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It features 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should be much faster than the Radeon R9 M375 in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 489088 (1389%)

Texel Rate

The Radeon RX 6900 XT will be a lot (about 1338%) more effective at AF than the Radeon R9 M375. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 543400 (1338%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6900 XT is the winner, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R9 M375		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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
