Radeon R9 M380 vs Radeon RX 570

Intro

Compare those specifications to the Radeon RX 570, which has a clock frequency of 1168 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 256-bit bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 570 should theoretically be quite a bit superior to the Radeon R9 M380 overall. (explain)

Radeon RX 570		229376 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 570 is much (more or less 274%) more effective at texture filtering than the Radeon R9 M380. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 109504 (274%)

Pixel Rate

The Radeon RX 570 will be quite a bit (more or less 134%) more effective at FSAA than the Radeon R9 M380, and should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 570		37376 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 21376 (134%)

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 data (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
