Over the past 12 months, Intel has slowly started to disclose information about its first hybrid x86 platform, Lakefield. This new processor combines one ‘big’ CPU core with four ‘small’ CPU cores, along with a hefty chunk of graphics, with Intel setting out to deliver a new computing form factor. Highlights for this processor include its small footprint, due to new 3D stacking ‘Foveros’ technology, as well as its low standby SoC power, as low as 2.5 mW, which Intel states is 91% lower than previous low power Intel processors. Today’s announcement comes in two parts: first, the specifications.

Intel will debut these two SKUs in its first generation of Lakefield. These CPUs will find homes in premium, always-connected laptops, such as the Samsung Galaxy Book S expected in markets this month, the Lenovo ThinkPad X1 Fold, coming later this year, and in the Microsoft Surface Book Neo.

Both SKUs will feature one big ‘Sunny Cove’ CPU core, along with four little ‘Tremont’ Atom CPU cores. Both sets of cores will have access to a 4 MB last level cache, although Intel has not yet disclosed what sort of cache this is.
These new form factors look incredible!

maybe for home/edu users.

even surface is still too unstable for your standard end user many times. MS can't figure out how to get around "stuff in bag" syndrome (we call it) which most users require level 1 service to resolve. That, and I/O degradation that requires depot service to resolve further makes the device clunky to work with in any meaningful corporate fashion for long periods of time.

We only have two left in the environment, and they'll be replaced with HP x360s when their time comes. It's a truly superior, vastly less expensive, reliable, and durable product. Oh! They even come with functional keyboards. pretty legit stuff.

we're almost to a legit pokedex though, that's pretty cool I guess.

I like the idea of ultra low power intel chips, but I don't really understand the use case. Tablets in this form factor are already exist with Ice Lake U. From a consumer stand point I can't see a scenario where this makes a lot of sense.

Maybe intel will make another run at mobile phones.

As far as I have seen, all the "always connected" devices are running snapdragon, even the Surface with LTE is running a snapdragon. I'm not sure why there aren't LTE modems on existing x86 platforms, but it looks like this processor will be what brings that to the table.

Windows scheduling disaster will hit these devices hard. Linux is the only proper OS for machines running these chips.

Windows tablets are as good as dead, Intel totally failed with their chip giveaways to OEM's and neither Baytrail nor that (overheating) Cherrytrail managed to make a dent in the market. So, do you want an LTE modem on your motherboard? You can buy a USB adapter for it, I definitely don't need another point of failure on my board and my PC's are already permanently connected to the internet with wires, I don't need LTE on my devices, my phone has it already.

I thought mobile core based tablets drained if you let them sit for a few days on sleep while atom tablets could be forgotten and refound and still have battery. And still used much more battery than atom tablets. But atom tablets are slow and kind of jerky while core based ones run ram and ssd's at full speed. This is combining the best of both.

What is killing Windows tablets is how well the old ones still work: https://www.userbenchmark.com/UserRun/22356012 from 2014 and still out of reach of AMD and ARM at 6w.

I personally would love a big.LITTLE design on desktop CPUs. Why not have 4-6 low power, small cores that Windows can dedicate to all the crap it processes in the background? Then leave 8 big cores for your actual gaming and real work where threads of background junk no longer vie for core execution time.

Obvious troll is obvious, those M series throttle so hard they are barely useful for anything other than rendering desktop.

Yes, the throttling is brutal as my screenshot from a couple of minutes ago on my fanless $145 7140 shows. I did undervolt with XTU though.

But for the first few seconds, it runs full speed and is as fast as a desktop FX chip for all normal tablet tasks like web, media, light office, etc.

In a fanless tablet. These new chips will crush Broadwell core m in battery life and performance.

By Built-in Benchmark Queen:
My 2.5 years old delidded 7980xe @ 4600mhz all core with 49ns memorylatency (4000c16 twekaed) is faster than 3950x max overclocked on water in every scenario. Pretty good for a ancient cpu
In gaming it has no chance vs my new 10900k @ 5400mhz and 4600c16 tweaked memory. ~35ns memorylatency.
