Radeon R7 240 28800 MB/sec
Difference: 44800 (156%)

Texel Rate

The Radeon R7 250 will be quite a bit (approximately 64%) faster with regards to texture filtering than the Radeon R7 240. (explain)

Radeon R7 250 24000 Mtexels/sec
Radeon R7 240 14600 Mtexels/sec
Difference: 9400 (64%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R7 250 is the winner, and very much so. (explain)

Radeon R7 250 8000 Mpixels/sec
Radeon R7 240 5840 Mpixels/sec
Difference: 2160 (37%)

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 information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

I'm purchasing the AMD A10-7850K APU. This APU can support the R7 240 or 250, however I was unclear which one to choose because it was tough to find real good data on the two GPU's whit side by side comparisons. The information provided in this site spelled out the differences to a novice like me so I could understand the differences between them and improved my knowledge. Thanks!

GAbriel says:

I have to say I am impressed by the 7850k by itself. Obviously with the R7 250 it will perform even better. I get around 30-50 on High details for most games. I heard that with BF4 that it gets around 40 with crossfire, which is awesome to say the least.
