Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 950, in theory, should be quite a bit faster than the Radeon R9 M265X overall. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 33728 (47%)

Texel Rate

The GeForce GTX 950 is quite a bit (about 114%) better at texture filtering than the Radeon R9 M265X. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 26152 (114%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 950 is the winner, by far. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 23568 (256%)

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 past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 can be processed in one second. This number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
