Radeon R7 260X vs Radeon R9 M270X

Intro

Compare that to the Radeon R9 M270X, which has a clock frequency of 725 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 260X should be 44% faster than the Radeon R9 M270X in general, due to its higher data rate. (explain)

Radeon R7 260X		104000 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 32000 (44%)

Texel Rate

The Radeon R7 260X should be much (more or less 112%) faster with regards to texture filtering than the Radeon R9 M270X. (explain)

Radeon R7 260X		61600 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 32600 (112%)

Pixel Rate

The Radeon R7 260X should be much (approximately 52%) better at AA than the Radeon R9 M270X, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R7 260X		17600 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 6000 (52%)

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 MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. 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 also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
