Radeon R7 250X 2GB vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which comes with GPU clock speed of 825 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 250X 2GB is 13% faster than the Radeon R7 M260X overall, because of its higher bandwidth. (explain)

Radeon R7 250X 2GB		72000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R7 250X 2GB will be much (approximately 102%) faster with regards to AF than the Radeon R7 M260X. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 20200 (102%)

Pixel Rate

The Radeon R7 250X 2GB should be much (more or less 142%) faster with regards to anti-aliasing than the Radeon R7 M260X, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 9400 (142%)

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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its 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 clock 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
