Radeon R7 370 2G vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which has core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 370 2G should be 87% quicker than the Radeon R9 M380 in general, because of its greater bandwidth. (explain)

Radeon R7 370 2G		179200 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 83200 (87%)

Texel Rate

The Radeon R7 370 2G should be much (about 56%) faster with regards to texture filtering than the Radeon R9 M380. (explain)

Radeon R7 370 2G		62400 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 22400 (56%)

Pixel Rate

The Radeon R7 370 2G is quite a bit (more or less 95%) more effective at anti-aliasing than the Radeon R9 M380, and will be capable of handling higher resolutions better. (explain)

Radeon R7 370 2G		31200 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 15200 (95%)

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 data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 ROPs 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
