Radeon R7 250X 2GB vs Radeon R9 M365X

Intro

The Radeon R7 250X 2GB comes with a GPU clock speed of 1000 MHz, and the 2048 MB of GDDR5 memory is set to run at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon R9 M365X, which features a clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R7 250X 2GB is a small bit (more or less 8%) more effective at anisotropic filtering than the Radeon R9 M365X. (explain)

Radeon R7 250X 2GB 40000 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 3000 (8%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is superior to the Radeon R9 M365X, though only just barely. (explain)

Radeon R7 250X 2GB 16000 Mpixels/sec
Radeon R9 M365X 14800 Mpixels/sec
Difference: 1200 (8%)

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 (counted in MB per second) that can be moved past 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 type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
