Radeon R7 M260X vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which has GPU clock speed of 725 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260X is 100% faster than the Radeon R7 M265 in general, because of its higher data rate. (explain)

Radeon R7 M260X		64000 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 32000 (100%)

Texel Rate

The Radeon R7 M260X is just a bit (more or less 14%) faster with regards to AF than the Radeon R7 M265. (explain)

Radeon R7 M260X		19800 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 2400 (14%)

Pixel Rate

The Radeon R7 M260X will be a bit (approximately 14%) faster with regards to full screen anti-aliasing than the Radeon R7 M265, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R7 M260X		6600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 800 (14%)

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 max amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at 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 calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
