Radeon R9 M380 vs Radeon RX Vega 64

Intro

Compare those specs to the Radeon RX Vega 64, which features a core clock speed of 1247 MHz and a HBM2 memory speed of 1890 MHz. It also makes use of a 2048-bit bus, and makes use of a 14 nm design. It features 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 64 should be 416% quicker than the Radeon R9 M380 overall, because of its higher 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 should be a lot (approximately 698%) more effective at texture filtering than the Radeon R9 M380. (explain)

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

Pixel Rate

The Radeon RX Vega 64 should be a lot (more or less 399%) better at anti-aliasing than the Radeon R9 M380, and should be able to handle higher resolutions better. (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 largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
