Radeon R7 250 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which has core clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 250 should theoretically be a small bit superior to the Radeon R9 M375X overall. (explain)

Radeon R7 250		73600 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M375X should be quite a bit (more or less 69%) better at texture filtering than the Radeon R7 250. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 16600 (69%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375X is the winner, and very much so. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 8240 (103%)

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 information (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If 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 high 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 number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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