Radeon R9 M380 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which features core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 memory. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 470 should in theory perform quite a bit faster than the Radeon R9 M380 overall. (explain)

Radeon RX 470		211200 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 115200 (120%)

Texel Rate

The Radeon RX 470 is a lot (more or less 196%) faster with regards to AF than the Radeon R9 M380. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 78528 (196%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 470 is the winner, and very much so. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 13632 (85%)

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 maximum amount of information (in units of MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
