Radeon R7 M260X vs Radeon R9 M375X

Intro

Compare that to the Radeon R9 M375X, which uses a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should in theory perform a little bit faster than the Radeon R7 M260X overall. (explain)

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

Texel Rate

The Radeon R9 M375X should be much (about 105%) better at AF than the Radeon R7 M260X. (explain)

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

Pixel Rate

The Radeon R9 M375X is quite a bit (more or less 146%) better at AA than the Radeon R7 M260X, and also should be able to handle higher resolutions without slowing down too much. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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