Radeon R9 M375X vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has set the core frequency at 1156 MHz. The HBM2 memory runs at a speed of 1600 MHz on this particular model. It features 3584 SPUs along with 224 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX Vega 56 should in theory be a lot 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 (about 538%) more effective at AF than the Radeon R9 M375X. (explain)

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

Pixel Rate

The Radeon RX Vega 56 will be much (more or less 356%) better at AA than the Radeon R9 M375X, and also able to handle higher resolutions without losing too much performance. (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 information (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 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 AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
