Radeon R7 250X vs Radeon R9 M275X

Intro

The Radeon R7 250X comes with a GPU core speed of 1000 MHz, and the 1024 MB of GDDR5 RAM runs at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.

Compare that to the Radeon R9 M275X, which has a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M275X 50 Watts
Radeon R7 250X 95 Watts
Difference: 45 Watts (90%)

Memory Bandwidth

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

Texel Rate

The Radeon R7 250X is a little bit (approximately 11%) more effective at texture filtering than the Radeon R9 M275X. (explain)

Radeon R7 250X 40000 Mtexels/sec
Radeon R9 M275X 36000 Mtexels/sec
Difference: 4000 (11%)

Pixel Rate

The Radeon R7 250X should be a bit (about 11%) faster with regards to full screen anti-aliasing than the Radeon R9 M275X, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon R7 250X 16000 Mpixels/sec
Radeon R9 M275X 14400 Mpixels/sec
Difference: 1600 (11%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video 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 could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
