Intel Planning 14nm "Ozark Lake" 16-core Processor for Spring 2021

TechPowerUp has learned that Intel is planning to bring 16 cores onto the mainstream desktop platform by Spring 2021 by implementing a similar chip-design philosophy as AMD: MCMs. The new "Ozark Lake" processor will pack up to 16 cores and 32 threads by decoupling the "core" and "uncore" components of a typical Intel mainstream processor.

Intel will leverage the additional fiberglass substrate floor-space yielded from the new LGA1700 package to create a multi-chip module that has two [kinds of] dies, the "core complex" and the "uncore complex." The core complex is a 14 nm die purely composed of CPU cores and an EMIB interconnect. There will be as many as 16 "Skylake" cores in a conventional ringbus layout, and conventional cache hierarchy (256 KB L2$ and up to 2 MB/core L3$). The lack of uncore components and exclusive clock and voltage domains will allow the CPU cores to attain Thermal Velocity Boost Pro speeds of up to 6.00 GHz, if not more.
The core complex connects to another, smaller die on the package called the "uncore complex," using EMIB. This die packs all of the chip's I/O. Among its key components include a dual-channel DDR4 memory controller, a PCI-Express gen 4.0 root complex with 28 lanes (16 toward PEG, 8 toward the DMI 4.0 chipset bus, and 4 toward an "accelerated M.2 slot" (working title), or perhaps even an Optane persistent memory slot). Also featured will be an Intel Xe-architecture based iGPU with roughly 1 TFLOP/s raw compute power. The modularity of the MCM will allow Intel to build lower-core count SKUs by simply placing smaller 10-core, 8-core, or 6-core dies next to the uncore complex.

Intel has, in the past, built an MCM with the exact same floor-plan and division of labor, "Clarkdale," circa 2010. Our well placed sources in the motherboard industry pin a soft-launch date on April 1, 2021, unless delayed by COVID-19.

Update 07:07 UTC: We reached out to Intel for comments and received an unexpected response: "We do not comment on unreleased products, but we're committed to saving the world by keeping college kids away from irresponsible spring break parties during a pandemic."

6.0 GHz if not more on a single core? How is that possible?

6GHz on 14nm... wonder how hot that'll run and how much power it'll use.

Good to see that after six years, Intel is still stuck on 14nm.

On a more serious note, also good to see that MCMs are the way forward. More modular and probably much more cost effective.

Off I go to an ill-advised spring-break party so I can be apprehended by Intel employees.

No, GeeBee wants to give you a CPU so good that you forget how to spring break.

If their Thermal Velocity Boost thing really is the very best, maybe it'll hit 6.9GHz?

I probably won't be able to get one until April 31st, 2021.

I wonder if this is a Jim Keller idea since Intel poached him over from AMD. Anyway, whatever success here is going to be limited by 14nm. It is surprising that they are still planning a radical redesign on 14nm for 2021, when they are talking about 7nm to launch in Q4 2021. I wonder this means there is some delay in 10 or 7nm if this is true. There will be rework in design taking the 14nm to 7nm.

I was expecting this year's series of processors to come out at April 1st. I guess I will have to wait one year to see that happening.

If Intel is able to hit 5.3Ghz now, it may be possible for them to tweak and push the chip hard to get it to 6Ghz. However, it does not resolve the issue that it will be a power hog/ inefficient no matter how you cut it. This is especially so when they keep to 14nm. While this will be a single core boost speed, I wonder how much power will a 16 core Intel 14nm chip require. Considering existing 10 core chip and all core turbo on is burning through north of 300W, I think this 16 core chip is unlikely to fare better, if not significantly worst.

Usually, around this time of year, boring low effort troll posts start masquerading as news items.

Glad to see that Intel found AMD's glue gun. Nice of AMD to leave it in front of Intel's offices on a special day like today! :D

ROFL gotta be a wind up this......."ozark lake" "14mm @ 6Ghz" "LGA 1700" Checks calendar and asks wife what day is it...


Edit : Ohhh and i finally got my long service badge :) v happy!

This is gold.

Well played!

The most hilarious part is maybe even that this doesn't sound far fetched from Intel's point of view at all.

You're all laughing now but who's gonna have the last laugh when Intel actually releases a 14nm chip in 2021. Skylake v15

.....all?......all will be laughing. Even Intel execs will be laughing, but that will be more of a nervous laugh.

Wow 16 cores, more than 6 ghz core clock and 14 NM. What a nice cpu very fast while keeping me warm and comfy in the winter.

There is just one little problem, the day we have today. So yeah I declare this for:
