I think Intel's strategy right now is to just launch whatever's ready, whenever it's ready. They don't really have the luxury of artificially spacing out releases to give the appearance of a consistent yearly cycle. Would explain the odd cadence, at least.

UP3 RKL-U has SGX
15W RKL-U goes up to 88A (lul at potential 105W power draw at stock)
What's so funny?

You do know that Cometlake-U is already at 85A right? Icelake is at 70A. That has nothing to do with TDP. Intel chips have PL3 and PL4 values.

In mobile PL1 is king.

That's precisely what's funny. And I know it has nothing to do with TDP specifically, however what it has got to do with devices like this that are allowed to sustain their PL2s which are in excess of 70W.

That's what I find funny. Thanks to CML-U and RKL-U, we get to enjoy -H devices disguised as -U devices. It's hilarious.

Well that, and also it gives is a great taste of sustained performance under heavy load. I'll stop there before I start ranting about the gloriousness of Renoir.

We have other threads for that.

Devices that allow too much time above rated TDP are going to have horrible battery life and/or suffer from throttling unless the cooling solutions are excellent.

They could easily solve that by having different behavior when on battery or on power adapter.
I think they have done that in the past with the pentium iii mobile.

On my Dell XPS 13, I can easily limit this behaviour in the BIOS to make sure the 8565U does not boost to 4.6 GHz and you can get 10+ hours of battery.
When limiting this massive boost the XPS 13 can operate without the fan turned on at high rpm and the laptop is silent and quite cool. Downside is you can forget any intensive task like compiling in visual studio or run some VM.
I use it for Powerpoint and office and for remote desktop to my workstation or to ssh to my cloud VM instances

I'm not sure that laptop vendors want to design cooling solutions for 'just in case you're always connected' in an ultraportable laptop. Without sufficient cooling it doesn't matter how much power you provide for your chip.

You are right. But remember that intel is already 'cheating' in benchmarks with those 15W TDP u series cpus by allowing them to go up to 45W TDP. It's just extending that 'trick' when using the power adapter.

Not to go off-topic, but just read the new Renoir reviews.... Even at 90 watts they are losing to a 35 watt cpu.. The cheating is over ???

There are reasons not to do that. See below.

On my Dell XPS 13, I can easily limit this behaviour in the BIOS to make sure the 8565U does not boost to 4.6 GHz and you can get 10+ hours of battery.
When limiting this massive boost the XPS 13 can operate without the fan turned on at high rpm and the laptop is silent and quite cool. Downside is you can forget any intensive task like compiling in visual studio or run some VM.

At that point, though, why has the OEM provided a CPU that can boost higher? The end user wants battery life and performance, ideally. Having to choose one or the other is not so great. Also, presumably the lappie has a cooling solution that can handle the higher boost behavior, at least in bursts. Now the cooling solution is overbuilt. Some beancounter somewhere must be having fits. Poor baby.

I'm not sure that laptop vendors want to design cooling solutions for 'just in case you're always connected' in an ultraportable laptop. Without sufficient cooling it doesn't matter how much power you provide for your chip.
That's what I was sort-of thinking. OEMs are notorious for not wanting to lay out cash for extensive cooling unless it fits a majority of use cases and/or unless they can charge and arm and a leg and get away with it.

If that's the case Intel is about to start water cooling it's laptop cpus :D
Human bodies are full of water. The ultimate in portable computing! Sink the heat into people as they use the laptop!

I know you are joking, but you have no idea how many people actually burned their legs because of 100ºC objects sitting on their legs for too long...

Already read some, a little disappointing with the type of laptops and intel cpus they used to make the comparison.
The form factor is not the same 15"/17" vs 14", and the cpus, Linus even used one intel mobile 120 watts cpu!

They tried hard to keep intel to show up above in the charts than they ever should have, or they tried really hard to even make intel cpus more pathetic.

I don't see a reason to buy intel laptops, unless people like to pay for more than they should.

Are you guys ready to read many news talking about announcements and leaks of way too good to be true products because it's the first of April? I can hardly wait to witness so much creativity from the press

I was thinking of just that. But I'm sure we could rig up a system to sink water into the back as well. Lots of surface area!

Rumour has it these are the final specs for Comet Lake-H. Unveils tomorrow.
