Radeon R9 M375X vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which has core speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 6600 XT should in theory be quite a bit superior to the Radeon R9 M375X overall. (explain)

Radeon RX 6600 XT		262144 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 190144 (264%)

Texel Rate

The Radeon RX 6600 XT should be quite a bit (more or less 520%) more effective at anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 211304 (520%)

Pixel Rate

The Radeon RX 6600 XT should be quite a bit (approximately 676%) better at full screen anti-aliasing than the Radeon R9 M375X, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 109712 (676%)

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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are applied per second. This number is worked out by multiplying the total amount 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
