Bold: what's the 6 core-based successor called?

Underline: wait, WAT. How is that even possible? Isn't the 4700U a 15W chip and the 7700 is a 45w chip? What am I missing?

Cinebench R20:
Intel i7 7700HQ (45w) (4c/8t) = single thread score : 370.   Multi thread score : 1774.
AMD Ryzen 7 4700U (15w) (8c/8t) = single thread score : 472.   Multi thread score : 2647.

the 7700HQ is a 4 core cpu.
the 4700U is a 8 core cpu.

"how is that even possible? Isn't the 4700U a 15W chip?"

Yes it is :)

AMD did quite alot of optimisations to get their "U" line to be as power effecient as possible.

Part of it is AMD is useing a 7nm chip, and Intel's 7700HQ is on a 14nm node.

Another part is that Intel wasn't really trying with the mobile 7xxx series. Just compare the models of these last years, including the upcoming Comet Lake model:

Model	Cores/Threads	Base clock (Ghz)	Single-core turbo (Ghz)	Allcore turbo (Ghz)
7920HQ	4/8	3.1	4.1	3.7
8750H	6/12	2.2	4.1	3.9
9750H	6/12	2.6	4.4	4.0
10875H	8/16	2.3	4.9 (5.1 with TVB)	?

You can see that the gains in performance have been massive ever since.

I'm sure the 10710U would also beat the 7700HQ nowadays. Like I said, Intel wasn't even trying with the 7000 series
