While these may look good, Haswell Celeron really outperforms them to a large margin with a similar price.

agree..
still my IVY pentium still works..

Power consumption
Minimal difference, unless you need passive cooling at a low price.

This shows how decent the Haswell Celerons are.

Athlon 5350 is less than 40W
J1900 is even less with less than 35W

Athlon 5350 is less than 40W
J1900 is even less with less than 35W
It they were 10W vs 20W, it's a 50% difference,
but now 40W vs 60W, there isn't much advantage I can point out for the former (except for passive cooling, but I could do the same with more cost using the latter).

And this is talking about Full Load, which could be only 10% of the time,
where most of the time Haswell Celeron consumes only 17W idle (same as your test actually) - 40W (fair load I assume)of power for daily use.

Finally it is worth to point out the difference in performance (from Passmark):
Intel Celeron J1900 @ 1.99GHz  1,959  
Intel Celeron G1840 @ 2.80GHz  2,837  
with G1840 can decode 4k.
*AMD Athlon 5350 APU with Radeon R3  2,621  
Surprisingly the 5350 is actually close in score.

I do think New Atoms and AMD low power CPUs have the potential, but at this point they don't really shine imho.

我 i3-4130 都得啦
(IDLE , Full load 過 60W)

If it's fit in a notebook / ultrathin case, that's different case

Why Intel and AMD bother to "waste time" to make these new low-power but "marginal" performance
For fanless embedded system these are very useful , Celeron G1840/1820 just doesn't cut it.
(of coz some ppl always want more performance , even myself )

Even ARM side start pushing Quad Core powered smartphone as baseline model , if you still selling "Dual Core" it's hard for OEM/ODM to sell their product.

For normal case yes, but I managed to fit G1840 in a fanless case recently:

These low power CPUs were intended to be used on very low power devices, the desktop versions are actually by-products;
with the current trend, it's likely after 1-2 generations we will have latest micro-architecture Celerons running fanless with a heatsink like those on Atoms now.

Don't think so

Too similar in power consumption, it is pointless not to merge two microarchitectures
