Radeon R7 M360 vs Radeon R9 M385X

Intro

Compare all that to the Radeon R9 M385X, which features a core clock speed of 1100 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M385X will be 500% faster than the Radeon R7 M360 overall, because of its greater bandwidth. (explain)

Radeon R9 M385X		96000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The Radeon R9 M385X should be much (more or less 128%) faster with regards to AF than the Radeon R7 M360. (explain)

Radeon R9 M385X		61600 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 34600 (128%)

Pixel Rate

The Radeon R9 M385X will be quite a bit (about 96%) better at AA than the Radeon R7 M360, and should be capable of handling higher screen resolutions better. (explain)

Radeon R9 M385X		17600 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 8600 (96%)

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 MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
