Radeon R9 M375X vs Radeon RX Vega 56

Intro

Compare all that to the Radeon RX Vega 56, which comes with core speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs as well as 224 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX Vega 56 should perform quite a bit faster than the Radeon R9 M375X overall. (explain)

Radeon RX Vega 56		419430 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 347430 (483%)

Texel Rate

The Radeon RX Vega 56 will be much (approximately 538%) better at anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 218344 (538%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX Vega 56 is the winner, and very much so. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 57744 (356%)

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 data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 that the graphics card can possibly record to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
