Radeon R7 250X 2GB vs Radeon R7 M260X

Intro

Compare all that to the Radeon R7 M260X, which comes with a core clock frequency of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 250X 2GB should theoretically be just a bit faster than the Radeon R7 M260X in general. (explain)

Radeon R7 250X 2GB		72000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R7 250X 2GB will be quite a bit (more or less 102%) better at texture filtering than the Radeon R7 M260X. (explain)

Radeon R7 250X 2GB		40000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 20200 (102%)

Pixel Rate

The Radeon R7 250X 2GB is much (more or less 142%) faster with regards to AA than the Radeon R7 M260X, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R7 250X 2GB		16000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 9400 (142%)

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 max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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