GeForce GTX 950 vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which has GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 950		90 Watts
	Difference: 10 Watts (13%)

Memory Bandwidth

The Radeon RX 560 should in theory perform a little bit faster than the GeForce GTX 950 overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 950		105728 MB/sec
	Difference: 8960 (8%)

Texel Rate

The Radeon RX 560 is much (about 53%) more effective at AF than the GeForce GTX 950. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 26048 (53%)

Pixel Rate

The GeForce GTX 950 should be a lot (more or less 74%) more effective at full screen anti-aliasing than the Radeon RX 560, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 13968 (74%)

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 (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
