So what are the power numbers for this chip? Sure anything can beat M series chips if it uses more power. 

As mentioned in the article, the 7840u was designed for “thin and light” notebooks, ergo machines comparable to the MacBook Air (only with a fan or two). We won’t know stuff like power consumption and fan noise until this chip goes into an actual production model, but AMD is already writing cheques it may not be able to cash in terms of claims about potential performance, because some factors in any real-world comparison are going to rely on machines built by other companies.

And yet that still doesn’t answer the question about power numbers. 

We’ve got Intel chips meant for thin and light notebooks that melt them down. 

Actual, factual hard numbers is what we need to see. 

"Actual, factual hard numbers" are right here.

This is an impressive chip.

Power Mode	Quiet	Performance	Turbo/with PSU	Manual/with PSU
SoC SPL (= PL1)	9 Watts	15 Watts	25 / 30 Watts	15 / 30 Watts
SoC sPPT (= PL2)	14 Watts	20 Watts	30 / 43 Watts	20 / 43 Watts
SoC fPPT (= PL4)	17 Watts	25 Watts	35 / 53 Watts	25 / 53 Watts

Red = Turbo
Green = Performance

Quiet	Performance	Turbo	Turbo battery
CB R15 Multi	1180 points	1727 points	2397 points	2153 points
CB R15 Single	222 points	280 points	280 points	280 points

Whether this chip is in a handheld, laptop or mini desktop, it has a lot of potential.

I'd also note that the ASUS ROG Ally Z1 Extreme is only $699 USD with 16 GB LPDDR5-6400 RAM and 512 GB NVMe PCIe 4.0 SSD. So prices for devices with these chips appear to be quite reasonable.

Not doing extrapolations dude. I have no doubt it’s impressive. So are Intels best chips. 

I meant the actual numbers of the SOCs in question as they ran throughout the “benchmarks.” Actual power and thermals - while generating publicized performance. 

actual numbers for the actual part. Not you math project. 

and the world knows benchmarks are only a small part of the story and can be manipulated by less honest companies. Lots of testing has been done with apple silicon compared to processors that beat it in benchmarks only to see Apple Solicon win out in real world usage.

Z1 Extreme: 1180 @ 17 Watts [Quiet Mode setting] = 69 Points / Watt
M2: 1229 @ 19 Watts = 64 Points / Watt

Thanks for this, very interesting. Assuming there is no other graphics assistance in the ROG Ally than just what's on the Z1 Extreme, quiet mode is very comparable to the (regular) M2, except that instead of being slower, the M2 is faster ... AND still uses a bit less power.

Here's an initial performance per watt comparison using the Ryzen Z1 Extreme (equivalent to the 7840u, but targeted to handhelds) in the ASUS ROG Ally Z1 Extreme.



ASUS ROG Ally Z1 Extreme Specifications:

AMD Ryzen Z1 Extreme
16 GB LPDDR5-6400 (Dual-Channel)
512 GB NVMe PCIe 4.0

Devices:

ASUS ROG Ally Z1 Extreme (Z1 Extreme)
Apple MacBook Pro 13 2022 (M2)

Power consumption comparison using Cinebench R15 / Multi 64Bit (looped):

Z1 Extreme: 2397 @ 53 Watts [Turbo Mode (plugged in) setting] = 45 Points / Watt
Z1 Extreme: 2153 @ 35 Watts [Turbo Mode (battery) setting] = 61 Points / Watt
Z1 Extreme: 1727 @ 25 Watts [Performance Mode setting] = 69 Points / Watt
Z1 Extreme: 1180 @ 17 Watts [Quiet Mode setting] = 69 Points / Watt
M2: 1229 @ 19 Watts = 64 Points / Watt

your source link is broken! but that's phenomenal if true.
