Radeon R9 M380 vs Radeon RX Vega 64

Intro

Compare that to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 RAM is set to run at a speed of 1890 MHz on this specific card. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 64 will be 416% faster than the Radeon R9 M380 overall, due to its greater data rate. (explain)

Radeon RX Vega 64		495411 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 399411 (416%)

Texel Rate

The Radeon RX Vega 64 will be quite a bit (more or less 698%) better at AF than the Radeon R9 M380. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 279232 (698%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX Vega 64 is the winner, by far. (explain)

Radeon RX Vega 64		79808 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 63808 (399%)

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 MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
