GeForce GTX 950M vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which features GPU clock speed of 1090 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
Radeon RX 460 2GB		75 Watts
	Difference: 20 Watts (36%)

Memory Bandwidth

Performance-wise, the Radeon RX 460 2GB should in theory be much superior to the GeForce GTX 950M in general. (explain)

Radeon RX 460 2GB		112000 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 80000 (250%)

Texel Rate

The Radeon RX 460 2GB will be quite a bit (approximately 67%) faster with regards to anisotropic filtering than the GeForce GTX 950M. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 24480 (67%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 460 2GB is the winner, though not by far. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 2816 (19%)

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 moved across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of 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 per second.

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