" The Ryzen CPU slightly falls behind the popular notebook CPU Core i7-7700HQ (2.8 to 3.8 GHz, 45 Watt TDP, 6 MB L3 cache) here. Since most modern applications are multi-threaded, this is hardly important."
I disagree. Individual software performance is usually dictated by single cor performance. Specifically bloated software that doesn't take advantage of more than 1 core. It could be a CPU hoggy defragmenter like Defraggler, or a stock market trading software such as Fidelity ATP. Heck, even Windows Disk Cleanup is a single core CPU hog while analyzing the drive.
For that reason I would get a Coffee Lake 6-core 8700HQ 45w TDP laptop CPUe'd laptop.
The Ryzen 7 1700 is a desktop CPU, which means it is an energy hog while not delivering any better single core performance than a 45w CPU, or heck, even a 15w Coffee Lake 'u' CPU for short intervals at 4GHZ.
I do not see the logic behind buying this laptop. A 8700HQ would probably have a 6-core base clock of a good 2.4GHZ, 4-core 3.2GHZ or so, 1-core 4.2GHZ turbo or so. And, would likely find itself in a 4.2 pound MSI GS63VR style thin laptop.. or 5.3 pounds 17" version. So why lug around 10 pounds for more multitasking performance? Get a 16-core desktop for that purpose.
I would love to see AMD's Raven Ridge (codename for their mobile Ryzens) in 45w TDP variety (not just 35w and less like they have in the past!) to really compete with the 7700HQ, to bring up the clockspeed close to it. I hear RR will just be up to 4 cores unfortunately, so they best make the best of it, try to hold their own in the 4 core mobile space.
I hope they go beyond my expectations!
