Radeon R7 M360 vs Radeon R9 M380

Intro

Compare all that to the Radeon R9 M380, which features a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380 should in theory perform much faster than the Radeon R7 M360 overall. (explain)

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

Texel Rate

The Radeon R9 M380 is quite a bit (approximately 48%) faster with regards to AF than the Radeon R7 M360. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M380 is the winner, by far. (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 max amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
