Radeon R7 250X 2GB vs Radeon R7 M260

Intro

Compare those specifications to the Radeon R7 M260, which makes use of a 28 nm design. AMD has set the core speed at 715 MHz. The DDR3 RAM works at a speed of 1000 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 250X 2GB should in theory be quite a bit superior to the Radeon R7 M260 overall. (explain)

Radeon R7 250X 2GB		72000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R7 250X 2GB will be a lot (about 133%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 22840 (133%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250X 2GB is the winner, by far. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 10280 (180%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
