Radeon R7 M260X vs Radeon R9 M375X

Intro

The Radeon R7 M260X features a GPU clock 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 features 384 SPUs, 24 TAUs, and 8 ROPs.

Compare those specifications to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should theoretically be a small bit better 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 should be quite a bit (about 105%) better at anisotropic 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 running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is the winner, 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 MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
