Radeon R9 M380 vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which features core clock speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 memory. It features 3584 SPUs along with 224 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX Vega 56 should theoretically be a lot better than the Radeon R9 M380 in general. (explain)

Radeon RX Vega 56		419430 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 323430 (337%)

Texel Rate

The Radeon RX Vega 56 will be a lot (more or less 547%) more effective at AF than the Radeon R9 M380. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 218944 (547%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX Vega 56 is superior to the Radeon R9 M380, by a large margin. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 57984 (362%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
