GeForce 830M vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which features GPU core speed of 1175 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

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

Memory Bandwidth

As far as performance goes, the Radeon RX 560 should in theory be quite a bit better 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 should be a lot (approximately 357%) more effective at texture 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 will be quite a bit (about 128%) more effective at full screen anti-aliasing than the GeForce 830M, and also able to handle higher resolutions better. (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 largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
