Radeon R9 M370X vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which comes with a clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also makes use of a 256-bit memory bus, and uses a 14 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 470 should be quite a bit faster than the Radeon R9 M370X in general. (explain)

Radeon RX 470		211200 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 139200 (193%)

Texel Rate

The Radeon RX 470 will be quite a bit (approximately 270%) better at AF than the Radeon R9 M370X. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 86528 (270%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 470 is the winner, by a large margin. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 16832 (132%)

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 max amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
