Radeon R7 250X 2GB vs Radeon R9 M375

Intro

Compare all of that to the Radeon R9 M375, which features 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 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 250X 2GB, in theory, should perform much faster than the Radeon R9 M375 in general. (explain)

Radeon R7 250X 2GB		72000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 36800 (105%)

Texel Rate

The Radeon R9 M375 is just a bit (about 2%) more effective at texture filtering than the Radeon R7 250X 2GB. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375 is a better choice, though only just barely. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R7 250X 2GB		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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 max fill rate.
