Radeon R7 240 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which features a core clock frequency of 1015 MHz and a DDR3 memory speed of 1100 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375 is 22% quicker than the Radeon R7 240 in general, due to its greater bandwidth. (explain)

Radeon R9 M375		35200 MB/sec
Radeon R7 240		28800 MB/sec
	Difference: 6400 (22%)

Texel Rate

The Radeon R9 M375 should be quite a bit (approximately 178%) better at texture filtering than the Radeon R7 240. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon R7 240		14600 Mtexels/sec
	Difference: 26000 (178%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375 is the winner, and very much so. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R7 240		5840 Mpixels/sec
	Difference: 10400 (178%)

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 maximum amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 reach the maximum fill rate.
