Radeon R7 M360 vs Radeon R9 M380

Intro

Compare all of that to the Radeon R9 M380, which has a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 should be quite a bit faster than the Radeon R7 M360 in general. (explain)

Radeon R9 M380		96000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The Radeon R9 M380 is much (more or less 48%) more effective at texture filtering than the Radeon R7 M360. (explain)

Radeon R9 M380		40000 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 13000 (48%)

Pixel Rate

The Radeon R9 M380 is a lot (about 78%) more effective at FSAA than the Radeon R7 M360, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 M380		16000 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 7000 (78%)

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 largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
