Radeon R7 M260 vs Radeon R9 M265X

Intro

Compare that to the Radeon R9 M265X, which has GPU clock speed of 575 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M265X should theoretically be quite a bit superior to the Radeon R7 M260 overall. (explain)

Radeon R9 M265X		72000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon R9 M265X should be a lot (more or less 34%) better at anisotropic filtering than the Radeon R7 M260. (explain)

Radeon R9 M265X		23000 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 5840 (34%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M265X is the winner, by far. (explain)

Radeon R9 M265X		9200 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 3480 (61%)

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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
