Radeon R9 M380 vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which features a GPU core clock speed of 1156 MHz, and 8192 MB of HBM2 RAM running at 1600 MHz through a 2048-bit bus. It also is made up of 3584 SPUs, 224 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX Vega 56 should theoretically be quite a bit superior to the Radeon R9 M380 overall. (explain)

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

Texel Rate

The Radeon RX Vega 56 is quite a bit (approximately 547%) faster with regards to texture filtering than the Radeon R9 M380. (explain)

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

Pixel Rate

The Radeon RX Vega 56 will be a lot (more or less 362%) more effective at FSAA than the Radeon R9 M380, and should be able to handle higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
