Radeon R7 M260X vs Radeon R9 M375X

Intro

The Radeon R7 M260X has a GPU core speed of 825 MHz, and the 2048 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Compare that to the Radeon R9 M375X, which features a clock speed of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit memory 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

The Radeon R9 M375X, in theory, should be a small bit faster than the Radeon R7 M260X in general. (explain)

Radeon R9 M375X 72000 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon R9 M375X is much (more or less 105%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

Radeon R9 M375X 40600 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 20800 (105%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M375X is a better choice, by far. (explain)

Radeon R9 M375X 16240 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 9640 (146%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total 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 a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
