Radeon R7 250 vs Radeon R9 M365X

Intro

The Radeon R7 250 uses a 28 nm design. AMD has set the core frequency at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1150 MHz on this card. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Compare those specs to the Radeon R9 M365X, which has GPU clock speed of 925 MHz, and 4096 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 250, in theory, should perform a little bit faster than the Radeon R9 M365X in general. (explain)

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

Texel Rate

The Radeon R9 M365X should be quite a bit (more or less 54%) more effective at 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

If using lots of anti-aliasing is important to you, then the Radeon R9 M365X is the winner, and very much so. (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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
