Radeon R7 260X vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which has a core clock frequency of 1015 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 260X should in theory be much superior to the Radeon R9 M375X in general. (explain)

Radeon R7 260X		104000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 32000 (44%)

Texel Rate

The Radeon R7 260X should be much (more or less 52%) better at texture filtering than the Radeon R9 M375X. (explain)

Radeon R7 260X		61600 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 21000 (52%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 260X is superior to the Radeon R9 M375X, though not by far. (explain)

Radeon R7 260X		17600 Mpixels/sec
Radeon R9 M375X		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 max amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, 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 maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
