Radeon R7 250 vs Radeon R9 M375X

Intro

The Radeon R7 250 comes with a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare all that to the Radeon R9 M375X, which has GPU clock speed of 1015 MHz, and 4096 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 250 should perform a small bit faster than 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 is quite a bit (more or less 69%) more effective 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 a high screen resolution 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
