Radeon R7 250X 2GB vs Radeon R9 M370X

Intro

The Radeon R7 250X 2GB features a GPU core speed of 1000 MHz, and the 2048 MB of GDDR5 RAM runs at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare those specifications to the Radeon R9 M370X, which features core speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 250X 2GB is a lot (about 25%) faster with regards to texture filtering than the Radeon R9 M370X. (explain)

Radeon R7 250X 2GB 40000 Mtexels/sec
Radeon R9 M370X 32000 Mtexels/sec
Difference: 8000 (25%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 250X 2GB is superior to the Radeon R9 M370X, and very much so. (explain)

Radeon R7 250X 2GB 16000 Mpixels/sec
Radeon R9 M370X 12800 Mpixels/sec
Difference: 3200 (25%)

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 (in units of megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
