Radeon R7 360 vs Radeon R9 M385X

Intro

Compare that to the Radeon R9 M385X, which features a clock speed of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 360 should in theory be a little bit superior to the Radeon R9 M385X overall. (explain)

Radeon R7 360		104000 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 8000 (8%)

Texel Rate

The Radeon R9 M385X is a lot (approximately 22%) faster with regards to anisotropic filtering than the Radeon R7 360. (explain)

Radeon R9 M385X		61600 Mtexels/sec
Radeon R7 360		50400 Mtexels/sec
	Difference: 11200 (22%)

Pixel Rate

The Radeon R9 M385X will be a small bit (more or less 5%) more effective at FSAA than the Radeon R7 360, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M385X		17600 Mpixels/sec
Radeon R7 360		16800 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 information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 colour ROPs by the the core clock speed. 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 - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
