GeForce GTX 950M vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 RAM works at a speed of 1100 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375 should in theory be a little bit better than the GeForce GTX 950M overall. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 3200 (10%)

Texel Rate

The Radeon R9 M375 will be a bit (approximately 11%) better at anisotropic filtering than the GeForce GTX 950M. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 4040 (11%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M375 is the winner, though not by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 1616 (11%)

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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
