Radeon R7 250 vs Radeon R9 M375X

Intro

The Radeon R7 250 comes with core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Compare those specs to the Radeon R9 M375X, which comes with core clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 250 should perform a bit faster than the Radeon R9 M375X in general. (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 (approximately 69%) faster with regards to anisotropic filtering than the Radeon R7 250. (explain)

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

Pixel Rate

The Radeon R9 M375X will be a lot (more or less 103%) more effective at anti-aliasing than the Radeon R7 250, and should be able to handle higher screen resolutions without slowing down too much. (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 max amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, 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 that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
