The guy who proposed the TAGE branch predictor back in 2006 (and invented other things) is now working at Intel.
The Intel Advanced Architecture Development Group (AADG) is responsible for creating the next leap in Microprocessor Design and the future of the x86 environment at Intel by helping to solve the ‘Innovator’s Dilemma’ when it comes to a new core design for Intel.
This dilemma can be simplified into finding the answers to questions like:
What legacy components of x86 that focused on end-user desktops are really required in a world with a more cloud focused approach?
If you could make any trade-off you wanted between Instructions per Cycle, Core Frequency & Power – what would you do?
In a world where information security is becoming more critical every-day, what should a processor core do differently?
Intel AADG Engineer responsibilities include:

Definition, design, verification, and documentation for x86 CPU microcode development which uses internal ops to implement x86 ISA

Make high level design choices for the microcode structure, frameworks, protocols, and algorithms

Now I've had some time for the @Intel announcements yesterday to sink in, here's my brain dump.
A number of analysts were quite reserved when @PGelsinger joined Intel, stating that no matter what he did, we wouldn't see it for years. I said straight away that Pat can steer the intent of the company as soon as he sat in the seat. Today is a clear message
That being said, Intel last week is still the same as Intel today. Saying stuff doesn't mean much unless Intel does pivot, and it will take a few years to enable that pivot, but there will be a strong undercurrent of things to come throughout, with a continuous focus on 2023

For what it's worth, Intel has been using Arm cores in its products for years. Some we know about, others we do not. Some Intel products contain solely Arm cores.

As for their own custom cores, Intel has had an Arm architecture license for around a decade, if not longer.
How much has Intel used that architecture licence? Golden question. Given that Arm's own cores go from the M0 for microcontrol, up to the X1 for performance, and R-series for real time, and lots in-between, it's hard to say.

A modern CPU has a lot of microcontrollers.
Just don't ask what secret sauce they already add for big customers.

Just found out that the company who installed my new boiler last year, has disappeared. They weren't the best price, but reasonable and 10-year warranty and free inspections. Worksmanship was poor though, and now that 10-year warranty and free inspections are worthless
I emailed them a couple months after installation to come back and fix things (holes in walls). No response. Just went into my loft and they've left old pipes everywhere, didn't clean up after themselves, empty boxes, thrown around the insulation
It seems like almost everything we've got other people to do on this house has been terrible. The stuff we've done ourselves is reasonable. But we only have limited skills and time.

Once again I have another FedEx parcel that was supposed to arrive by noon. 11:58, get an email saying 'delivery exception, customer not available'. Have they been here yet? Nope.

They do this so that they can say they 'attempted' delivery in time. Keeps the success rates high.
This is how they bid for contracts with big companies, on success rates. But they lie.

Last time this happened they still delivered two hours later. But because they said 'attempted, no-one available' by the delivery time, it still counts +ve for the metrics. When it shouldn't.
This is also why some couriers refuse to show you where the delivery driver is on a map, or a # in the chain you are. They claim it's because they do midday pickups for orders made that day. The truth is they want as little evidence as possible that they missed targets.

Xe and esports gaming on Tiger Lake Thread. Comments welcome.

I'm seeing a lot of reviews saying that Tiger Lake with Xe will be a boon for esports gamers, and then comments that integrated graphics is still high on the steam survey, so win win. /1
Everything that Intel has said about TGL, with it being on the premium 10SF process, with the leading generation CPU/GPU and TB4 and Athena/Evo, these ultra premium systems will not be priced for that 'casual gaming' market that plays on integrated graphics. /2
Those that game are more likely to spend that $1200+ on a gaming laptop with a 1660 Ti or something. The ultra portable is more for the worker and the road warrior. /3
