Radeon R9 M380 vs Radeon RX Vega 64

Intro

Compare those specifications to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has clocked the core speed at 1247 MHz. The HBM2 memory is set to run at a speed of 1890 MHz on this model. It features 4096 SPUs as well as 256 TAUs and 64 ROPs.

Radeon R9 M380		40000 Mtexels/sec
	Difference: 279232 (698%)

Pixel Rate

The Radeon RX Vega 64 is much (more or less 399%) more effective at FSAA than the Radeon R9 M380, and also will be capable of handling higher screen 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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
