Radeon R7 250 vs Radeon R9 M365X

Intro

The Radeon R7 250 has core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Compare all of that to the Radeon R9 M365X, which has a core clock frequency of 925 MHz and a GDDR5 memory speed 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 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 250 will be 2% quicker than the Radeon R9 M365X overall, because of its greater data rate. (explain)

Radeon R7 250 73600 MB/sec
Radeon R9 M365X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M365X will be much (more or less 54%) faster with regards to texture filtering than the Radeon R7 250. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon R7 250 24000 Mtexels/sec
Difference: 13000 (54%)

Pixel Rate

The Radeon R9 M365X should be a lot (approximately 85%) better at full screen anti-aliasing than the Radeon R7 250, and also able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon R7 250 8000 Mpixels/sec
Difference: 6800 (85%)

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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units of the card 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics 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 number of Render Output Units 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
