Radeon R7 250X 2GB vs Radeon R9 M375X

Intro

The Radeon R7 250X 2GB uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Compare all of that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R9 M375X should be just a bit (about 2%) better at AF 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

The Radeon R9 M375X is just a bit (about 2%) more effective at AA than the Radeon R7 250X 2GB, and should be capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 potential to get to the max fill rate.
