Radeon R9 M365X vs Radeon RX Vega 64

Intro

Compare those specifications to the Radeon RX Vega 64, which has a GPU core clock speed of 1247 MHz, and 8192 MB of HBM2 RAM running at 1890 MHz through a 2048-bit bus. It also features 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX Vega 64 is 588% quicker than the Radeon R9 M365X in general, because of its higher data rate. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 423411 (588%)

Texel Rate

The Radeon RX Vega 64 will be quite a bit (approximately 763%) faster with regards to AF than the Radeon R9 M365X. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 282232 (763%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX Vega 64 is the winner, by a large margin. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 65008 (439%)

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 max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 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. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
