GeForce 830M vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which features clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 Texture Address Units and 16 ROPs.

GeForce 830M		25 Watts
Radeon RX 560		80 Watts
	Difference: 55 Watts (220%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 560 should be much faster than the GeForce 830M in general. (explain)

Radeon RX 560		114688 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 100288 (696%)

Texel Rate

The Radeon RX 560 will be a lot (more or less 357%) more effective at anisotropic filtering than the GeForce 830M. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 58736 (357%)

Pixel Rate

The Radeon RX 560 is a lot (approximately 128%) faster with regards to AA than the GeForce 830M, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 10568 (128%)

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 (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
