I don't know how long it would take for 7nm to make it to a lower budget APU. It seems 12nm or 22FDX would have real advantages for anything under 2B or maybe even 3B transistors. Minimum area and perimeter for small 7nm dies probably get to be a problem.I don't know, Dali is honestly already more than I expected after they took their sweet time with it. Eventually Dali will be replaced by a 7nm part based on Renoir, possibly 4c then since 7nm density allows that while still making the die smaller. Then they could eventually add a sub-Dali 7nm part, significantly smaller and 2c. But it's clear those are on the very bottom of the whole food chain on a given node, so we will likely be well into the Zen 3 or even Zen 4 gen when those appear.
It looks like they are getting really close to getting 2c/4t to work on 6W. Short by 2W, and yet they did get 2c/2t to work at 6W:
Is Dali just Raven2 with maybe select wavers and minor fabrication tweak? Or is it a new stepping?
I think there' s gotta be some configuration issue from the manufacturer. Most brands would hesitate to put out a product with such issues, but with a noname that might fly."[Ematic" laptop (Walmart house brand)] sometimes gets in a "mood", and maxes out at 53% CPU used across both cores, and 0.80Ghz max clock. Guess passive cooling isn't good enough?
I know at 6w there are lower frequencies, but still. 1.2GHz was the minimum frequency I was able to clock my 15w A12 quadcore at; and at that freq it was actually fine at most things like movie and www under a dozen or so tabs.
I almost considered getting an hp walmart sku but then got cold feet after doubting the upgradability of said walmart sku. I'd be really hesitant to touch any brands/quality below the budget line of lenovo. Lenovo has been really price competitive in the budget category. The quality is still usually acceptable, especially in their mature laptops.
Is your emmc laptop upgradable in terms of RAM as well as sata (like adding a proper SSD)?
I got very lucky on the build quality of a A6-9225 ideaPad. The platform seems to have been based on earlier variants, one which I owned; and I was able to tell they ironed out the kinks. It sometimes takes manufacturers time and iterations to get product quality to where it should be.
Anyway, said low end laptop has been holding up great and is running well for the basics after upgrading to 8gb and a small SSD. Passed it down to a friend who uses it besides her chromebook. (Sometimes you just need a low end windows machine to drive some hardware like printers.) With the bigger screen it makes a better entertainment/movie station than the small chromebook.
As far as 6w Stoney I don't think they should make them except for the top bin. Maybe they could have a medium bin 6w-10w ctdp for tablets and throwaway emmc 12" notebooks, and name it A4 or something.
Anyway Stoney is just a temporary stopgap until Raven2 or Dali do better at low wattages. And then they're good for another 4+ years with Dali to address the lower and bottom range. Which also means they'd hopefully have something in the pipeline at or near the end of the concept stage.
In the year or two ahead, the next quadcore 7nm APU should address the mainstream as well as part of the lower end. I hope it is 10W oriented (6w to 15w for most mobile products) and Zen3. That should be ideal for the consumer for the next 5-8 years.
