The biggest irony is 2-cores (nevermind HT) anno 2019. . .

This is a low power U-series CPU. There is always room in the low-end for smaller CPUs. Its not like quad cores don't exist, even in the U-series.
Its not like AMD doesn't also have dual core mobile chips on the low end, fittingly also named "U", plus a dual-core Raven Ridge "Athlon" part for low-end desktops.

I understand what you are saying, but I thought that 4 real cores was new starting point - considering new lithography is just around the corner which negates power consumption equation.
BLEH!
I remember the Athlon XP where the boost to 512 kb of L2 cache was like "wow, this is half the chip". Intel must be taking some of this from the Skylake server stuff, maybe we'll see different L3, iunno...

Power Consumption =/= Manufacturing Cost.
If they can sell cheaper to make part, then they are making it.

Dual cores in the entry level were never a problem. The problem was how for a decade Intel insisted dual cores and quad cores were enough for the mainstream. Maybe they would have been if at the same time the clocks had gone up to 10GHz. However, Intel was only able to increase the clocks by 0.1-0.2GHz in a generation.

We consumers are hungry for progress even in entry level space, therefore dual core(s) should be history. That's the whole point of my posting.
intel obviously has other plans. . .

Yeah I wish Intel would have only focused on increasing core count over the years so I could have a 20 core cpu in my chromebook with a 30 minute battery life
Fox2232
$4000 chromebook? Kind of paradoxical. 😀 On other hand, I guess that if intel with their resources had 8C/16T CPUs in consumer sector for 4+ years, they would have started to develop even better power gating.
So, it would probably eat very little unless those cores end up loaded. But for servers one expects all cores to work, so no need to have full gating in place.

How fast is the L1, L2 and L3 cache anyway?
nhlkoho
That was sarcasm btw.....There's still a need for low power cpus that don't need a high core count. But the vocal minority would have you believe that everything is Intels fault for why there weren't higher core count cpus out sooner.

Imo what matters here is how 1core will look like.
And it's good to know that they will raise those numbers a bit, I hope other aspects will affect IPC too not just higher L cache
They were talking about completely new arch, no more sandybridge roots 😀
In rough
L1 ~1100gb/s (0.5ns)
L2 ~550 -650gb/s (2-3ns)
L3 ~250 -350gb/s (9-12ns)

If a dual core 4 thread CPU is faster and more efficient than a quad core that uses more power, efficiency both IPC and power are progress. Core count does not always mean more performance.

So this means Intel is finally going to release a new CPU arch in the near future??? Because they really need it otherwise AMD is going to kick Intel´s ass with Zen2.

Sure, instead of focusing only on making money and forgetting technology.
Btw, my low mid-range smartphone has eight cores. The whole phone was cheaper than my i5k.

no, anything with lake in the name is just a further refinement of the existing one.

thats , not the news i was expecting, looking more,and more like skylake 6.0.
a few more instructions than cannonlake and bigger caches, not very promising thus far.
I really thought they would have something interesting to show by now, maybe they really have stagnated to the point where they stopped trying, and now they are caught with their trousers down.
Fox2232
That would be one explanation for their talent hunting across industry.

No, icelake is a new arch. No more core roots that's been in use since sandybridge, up to incl. Cannonlake.
