Intel: Lakefield in 2020, Possible 5G on Foverosby Dr. Ian Cutress on December 11, 2019 1:15 PM EST
Update: Intel has sent over a statement clarifying that Lakefield will begin showing up in retail devices in 2020. And in particular that we should expect to see Lakefield devices as part of the Holiday 2020 device refreshes. Intel has stated that the comments made at the event were not specifically talking about a 'Lakefield Refresh' product, but a line of 'refresh products' based on Lakefield, and that we misheard the engineer's comments. It should be noted however that we have parity from other press in the room of our interpretation of the comments made.
At the IEEE International Electron Devices Meeting (IEDM) 2019, Intel had two package integration presentations, one on its Omni-Directional Interconnect and one on its 3D stacking Foveros technology. In the first talk, one of Intel’s engineers presenting at the conference said a rather curious thing that hasn’t been previously disclosed.
One of the highlights of 2019 as a whole has been Intel’s disclosures about its new 3D stacking, or ‘Foveros’, technology. The idea here is that using multiple silicon dies stacked on top of each other, you can decrease the overall die size of a chip but also increase the bandwidth if one of the silicon dies is dedicated to cache or memory. In the case of Intel’s first Foveros chip, Lakefield, we have one IO die and one compute die on different process nodes stacked together with additional PoP memory on top of the stacked design. Lakefield has been announced for two products so far, the Samsung Galaxy Book S and the Microsoft Surface Neo, both of which are scheduled to come to market in mid-2020.
Intel’s second announced Foveros chip is its new Xe-HPC architecture based graphics card design for high performance computing. Given the code name ‘Ponte Vecchio’, the new GPU is slated for a late 2021 launch and will use Foveros technology to help build out compute performance across 8 compute dies per slide, and Ponte Vecchio will have two slices per GPU. This GPU is being built primarily for the exascale-class Aurora supercomputer, which is set to be installed in the Argonne National Laboratories in 2021.
So what was the off-hand comment made at IEDM this year? On stage, an Intel Principle Engineer stated that by Holiday 2020, we should expect to see Lakefield Refresh based devices in the market. The engineer did state that first generation of Lakefield was already shipping, and that we should expect to see the next refresh of hardware/devices in finished consumer products by the end of 2020.
Intel is betting on its new Foveros technology, as with its EMIB interconnects, as a corner stone of certain areas of its product portfolio as we roll into the new decade. It will be interesting to see if the cost can be amortized into more price-sensitive areas. During the same IEDM presentation, the same principle engineer also mentioned that the Foveros stacking technology can also lend itself to adding on a modem into that stack – given that Intel recently announced a partnership with Mediatek to provide 5G connectivity for its products, one can make the assumption that at some point we’ll see a Foveros product with a modem too.
Hopefully Intel will disclose more in the early part of 2020.

boeush - Wednesday, December 11, 2019 - linkThey should've called it "Feaveros" - given the obvious implications for heat buildup and associated cooling challenges...
boeush - Wednesday, December 11, 2019 - linkSorry, bad spelling - should've been "Feveros" :-P
kc77 - Wednesday, December 11, 2019 - linkI thought Lakefield was actually supposed to launch this year? How can you have a second generation of something when the first generation hasn't even launched?
IntelUser2000 - Wednesday, December 11, 2019 - linkThe comment by the engineer suggests that devices using Lakefield are more like a Smartphone in that it has a longer development time to optimize for its mobile form factor.
With desktop chips, you can make the system the day the chip is announced. With laptops it takes some time as you need more work to optimize thermals and battery life. Smartphones take the most customization.
extide - Wednesday, December 11, 2019 - linkSo nobody else caught this:
"..8 compute dies per slice (sp), and Ponte Vecchio will have two slices per GPU"
That's 16 compute dies in a Ponte Vecchio GPU. Interesting.
edzieba - Thursday, December 12, 2019 - linkHas Intel confirmed the orientation of the Foveros dies? They've been calling it 'face to face' which implies that if the upper die is a normal flip-chip then the lower die has its metal layers facing up (i.e. non-flip), but that would mean it's backside solder balls mounting to the substrate are on the transistor side. There's been rumblings that instead If the lower die has it's metal layers facing down (flip chip) then the upper die would be transistor-down and the two would be bonded with transistor layers facing and interfacing. THAT would be a truly interesting orientation.
HStewart - Thursday, December 12, 2019 - linkSurface Pro Neo with Lakefield with dual 9 in screens sound like a cool addition. But I thought Lakefield was going ready this Christmas instead of next summer. But then again the other technology in Neo maybe delaying it with dual screens in PC laptop. We already seen what that has done with Galaxy Fold.
