Radeon R9 M375 vs Radeon RX Vega 56

Intro

The Radeon R9 M375 uses a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 memory runs at a speed of 1100 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Compare those specs 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 card. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 56 should perform much faster than the Radeon R9 M375 in general. (explain)

Radeon RX Vega 56 419430 MB/sec
Radeon R9 M375 35200 MB/sec
Difference: 384230 (1092%)

Texel Rate

The Radeon RX Vega 56 is a lot (about 538%) more effective at texture filtering than the Radeon R9 M375. (explain)

Radeon RX Vega 56 258944 Mtexels/sec
Radeon R9 M375 40600 Mtexels/sec
Difference: 218344 (538%)

Pixel Rate

The Radeon RX Vega 56 is much (approximately 356%) more effective at FSAA than the Radeon R9 M375, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX Vega 56 73984 Mpixels/sec
Radeon R9 M375 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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