Radeon R7 360 vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which features core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 360 will be 8% quicker than the Radeon R9 M380 overall, because of its higher bandwidth. (explain)

Radeon R7 360		104000 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 8000 (8%)

Texel Rate

The Radeon R7 360 is a lot (about 26%) faster with regards to texture filtering than the Radeon R9 M380. (explain)

Radeon R7 360		50400 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 10400 (26%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 360 is superior to the Radeon R9 M380, but it probably won't make a huge difference. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 800 (5%)

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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 reach the max fill rate.
