GeForce GTX 950M vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which has GPU clock speed of 1015 MHz, and 4096 MB of DDR3 memory set to run at 1100 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M375 should perform just a bit faster 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 is a small bit (more or less 11%) more effective at AF than the GeForce GTX 950M. (explain)

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

Pixel Rate

The Radeon R9 M375 is a bit (about 11%) more effective at anti-aliasing than the GeForce GTX 950M, and also able to handle higher resolutions better. (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 (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

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