Not to rain on the parade or anything, but aren't AMD laptops kinda run hot ("AMD turned my laptop into a toaster" is the common refrain)? I hear that complaint from almost all my peers who have AMD-based laptops.
AMD CPUs were not competitive for ~decade now, both in terms of performance and of power consumption.
It all changes with Ryzen though, which is why you might see that demand for ThinkPad A485 (while its predecessor, A475, was not popular). Mobile Ryzen is roughly on par with Intel Kaby Lake-R (8th gen quad-core mobile CPUs). Additionally, it features powerful integrated graphics (far better than Intel CPUs); and it does not have all these Intel security problems: there is no Intel ME, it's not affected by most of Meltdown/Spectre vulnerabilities, AMD has not been caught lying or deliberately concealing information of its vulnerabilities, etc.
Yes indeed the new AMD APU have very good graphical capabilities (Ryzen 2700 Pro runs Rise of the tomb raider at default graphics 30FPS stable on 1080p, very impressive for integrated graphics). It has comparable graphical capabilities of nvidia MX150. While being a little less performant (i guess it's because of the RAM versus graphic dedicated RAM), it has the advantages of:
- It's no additional costs, and actually it's cheaper than even a single intel chip (and mega cheaper than intel + nvidia setup)
- It not an option therefore every laptop has it.
- It's not a [censored] optimus setup which is a pain to setup on Linux and crashes all the time.
- You only gotta deal with AMD, not both intel and nvidia
- Only one chip to cool and to maintain.
- Easily overclockable since there's only one single chip.
- No outputs wired to the GPU like on the T420 or T540p, where the DisplayPort is wired to the nvidia dGPU therefore it must be turned on to use them which means cripples battery life only to use an output (horrible engineering if you ask me). Oh and the sound is impossible to route to a GPU output using an optimus setup on Linux because nvidia drivers are half-assed.
The cooling in the newer generation is lackluster because newer laptop manufacturers just picked up the new intel quad core chips and slapped them into the old design and called it a day (which isn't good engineering if you ask me... kinda lazy botched job). Kinda did the same for Ryzen chips which makes it throttle.
But from what i understand the chips have variable power consumption and can peak up to whatever the manufacturer allowed them to, so some chips under heavy load can go up to 45W power consumption. That means the potential for power is deffo present but the cooling solutions simply suck right now.
Most probably my next pick will be an AMD Ryzen ThinkPad so i'm deffo monitoring how this series performs.
