GeForce GTX 950M vs Radeon R9 M370X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should theoretically be a lot better than the GeForce GTX 950M in general. (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 (more or less 14%) faster with regards to AF than the Radeon R9 M370X. (explain)

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

Pixel Rate

The GeForce GTX 950M is a small bit (about 14%) faster with regards to AA than the Radeon R9 M370X, and should be capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number 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 speed of the chip. The better the texel rate, the better the video 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 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 Render Output Units 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
