Radeon R7 240 vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which features core clock speeds of 1100 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M385X should in theory be much better than the Radeon R7 240 in general. (explain)

Radeon R9 M385X		96000 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 67200 (233%)

Texel Rate

The Radeon R9 M385X should be much (more or less 322%) better at texture filtering than the Radeon R7 240. (explain)

Radeon R9 M385X		61600 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 47000 (322%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M385X is the winner, by far. (explain)

Radeon R9 M385X		17600 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 11760 (201%)

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 max amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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