Radeon R7 250X 2GB vs Radeon R9 M375X

Intro

The Radeon R7 250X 2GB makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Compare all that to the Radeon R9 M375X, which comes with 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 features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon R9 M375X will be a small bit (about 2%) more effective at anisotropic filtering than the Radeon R7 250X 2GB. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon R7 250X 2GB 40000 Mtexels/sec
Difference: 600 (2%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375X is superior to the Radeon R7 250X 2GB, though not by far. (explain)

Radeon R9 M375X 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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics 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 number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
