GeForce GTX 950M vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which comes with GPU core speed of 800 MHz, and 2048 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M370X should in theory be a lot superior to the GeForce GTX 950M overall. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 40000 (125%)

Texel Rate

The GeForce GTX 950M is just a bit (about 14%) better at AF than the Radeon R9 M370X. (explain)

GeForce GTX 950M		36560 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 4560 (14%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950M is superior to the Radeon R9 M370X, but only just. (explain)

GeForce GTX 950M		14624 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 1824 (14%)

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: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 potential to reach the maximum fill rate.
