GeForce 825M vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core frequency at 1175 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this specific card. It features 1024 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 825M		33 Watts
Radeon RX 560		80 Watts
	Difference: 47 Watts (142%)

Memory Bandwidth

Performance-wise, the Radeon RX 560 should in theory be quite a bit superior to the GeForce 825M in general. (explain)

Radeon RX 560		114688 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 100288 (696%)

Texel Rate

The Radeon RX 560 is quite a bit (about 453%) better at AF than the GeForce 825M. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 61600 (453%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 560 is the winner, and very much so. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 12000 (176%)

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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 get to the maximum fill rate.
