Radeon R7 250X vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which has GPU core speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 250X should in theory be quite a bit better than the Radeon R9 M375 in general. (explain)

Radeon R7 250X		72000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 36800 (105%)

Texel Rate

The Radeon R9 M375 is just a bit (more or less 2%) faster with regards to anisotropic filtering than the Radeon R7 250X. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 600 (2%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375 is a better choice, but only just. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 240 (2%)

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 in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the 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 chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
