Radeon R7 M260X vs Radeon R9 270X

Intro

Compare all of that to the Radeon R9 270X, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory runs at a frequency of 1400 MHz on this specific model. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 270X should theoretically be quite a bit better than the Radeon R7 M260X overall. (explain)

Radeon R9 270X		179200 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 115200 (180%)

Texel Rate

The Radeon R9 270X is a lot (about 304%) better at texture filtering than the Radeon R7 M260X. (explain)

Radeon R9 270X		80000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 60200 (304%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 270X is the winner, and very much so. (explain)

Radeon R9 270X		32000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 25400 (385%)

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 (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
