Radeon R7 260X vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which features a core clock frequency of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 260X should be 195% faster than the Radeon R9 M375 overall, due to its higher bandwidth. (explain)

Radeon R7 260X		104000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 68800 (195%)

Texel Rate

The Radeon R7 260X is quite a bit (more or less 52%) faster with regards to AF than the Radeon R9 M375. (explain)

Radeon R7 260X		61600 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 21000 (52%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 260X is the winner, but not by far. (explain)

Radeon R7 260X		17600 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 1360 (8%)

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 transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
