Radeon R7 M260 vs Radeon R9 M295X

Intro

Compare all of that to the Radeon R9 M295X, which comes with a clock speed of 750 MHz and a GDDR5 memory speed of 1375 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X will be 1000% quicker than the Radeon R7 M260 in general, because of its higher data rate. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 160000 (1000%)

Texel Rate

The Radeon R9 M295X will be a lot (more or less 459%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

Radeon R9 M295X		96000 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 78840 (459%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M295X is the winner, by far. (explain)

Radeon R9 M295X		24000 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 18280 (320%)

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 MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
