Radeon R7 250X 2GB vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which makes use of a 28 nm design. AMD has clocked the core frequency at 715 MHz. The DDR3 memory runs at a speed of 1000 MHz on this card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 250X 2GB should be 350% faster than the Radeon R7 M260 in general, because of its higher bandwidth. (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 quite a bit (approximately 133%) better at AF 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 running with a high screen resolution 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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
