Radeon R7 250X vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core speed at 1015 MHz. The DDR3 RAM is set to run at a speed of 1100 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X should be much faster than the Radeon R9 M375 overall. (explain)

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

Texel Rate

The Radeon R9 M375 will be a bit (about 2%) more effective at AF 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 screen resolution is important to you, then the Radeon R9 M375 is superior to the Radeon R7 250X, but not by far. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 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 AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
