GeForce 825M vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which features core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs 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

Theoretically speaking, the Radeon RX 560 is 696% quicker than the GeForce 825M in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 560 should be much (approximately 453%) more effective at AF than the GeForce 825M. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 560 is superior to the GeForce 825M, 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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