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


Intel Core I9 10875H is a ~25day old  Intel CPU (basically brand new).
its Comet Lake, a highly binned chip at 45watts.

Cinebench R20 scores:
Intel Core I9 10875H (45w)  : Single thread score : 498 ,   Multi thread score : 2853

AMD Ryzen 7 4700U (15w) :  Single thread score : 472 ,   Multi thread score : 2647
AMD Ryzen 7 4800U (15w) :  Single thread score : 480 ,   Multi thread score : 3306
AMD Ryzen 9 4900 HS (35w) : Single thread score : 495 ,   Multi thread score : 4288

So it beats the 4700U.
Theres a 4800U thats pretty close though.
I'd say its safe to claim the 4900HS is a faster chip, at lower power consumption.

Intel has been stuck at 14nm for too long.

"I'm sure the 10710U would also beat the 7700HQ nowadays."

Yes it would.

Cinebench R20:
Intel i7 7700HQ (45w) (4c/8t) = single thread score : 370.   Multi thread score : 1774.
Intel i7 10710U (15-25w) (6c/12t) -  single threaded score : 460  ,   multi thread score :  1863

AMD Ryzen 7 4800U (15w) (8c/16t) : Single thread score : 480 , Multi thread score : 3306

The 4800U beats the 10710U pretty handly though, at less power too.
Intel isnt the "best" cpu to own anymore inside a laptop, reguardless of if its at 15w or 45w.
