Radeon R9 M375X vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which has clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX Vega 64 should in theory be a lot better than the Radeon R9 M375X in general. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 423411 (588%)

Texel Rate

The Radeon RX Vega 64 should be much (approximately 686%) more effective at anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 278632 (686%)

Pixel Rate

The Radeon RX Vega 64 is quite a bit (about 391%) faster with regards to full screen anti-aliasing than the Radeon R9 M375X, and able to handle higher resolutions more effectively. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 63568 (391%)

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 transported past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
