Radeon R9 M385X 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 memory. It features 3584 SPUs as well as 224 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 56 should be a lot faster than the Radeon R9 M385X in general. (explain)

Radeon RX Vega 56		419430 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 323430 (337%)

Texel Rate

The Radeon RX Vega 56 is quite a bit (more or less 320%) faster with regards to texture filtering than the Radeon R9 M385X. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 197344 (320%)

Pixel Rate

The Radeon RX Vega 56 is a lot (about 320%) more effective at full screen anti-aliasing than the Radeon R9 M385X, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 56384 (320%)

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 max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 in a second.

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