Radeon R7 250 vs Radeon R9 M375X

Intro

The Radeon R7 250 features core 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 TAUs and 8 Rasterization Operator Units.

Compare all that to the Radeon R9 M375X, which comes with a core clock speed of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 250 should theoretically be a little 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 will be quite a bit (approximately 69%) more effective at AF than the Radeon R7 250. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375X is a better choice, by a large margin. (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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
