Intel Alder Lake: Confirmed x86 Hybrid with Golden Cove and Gracemont for 2021by Dr. Ian Cutress on August 14, 2020 1:05 PM EST

Following leaks is often a game of cat and mouse – what is actually legitimate and what might not be. Traditionally AnandTech shies away from leaks for that very reason, and we prefer to have multiple sources that are saying the same thing, rather than addressing every potential rumor on the blogosphere. Nonetheless, hints towards a new product from Intel, Alder Lake, have been cropping up over the past few months, including getting a small mention in Intel’s Q2 2020 earnings. The leaks have suggested that it would offer a mixed Hybrid x86 environment similar to Intel’s current Lakefield product that uses high-performance cores paired with high-efficiency cores. As part of Intel’s Architecture Day 2020, the company officially announced Alder Lake as a hybrid x86 product on its roadmaps.
In the roadmap and as part of the discussions, Intel’s Raja Koduri confirms that Alder Lake will be a combination of the Golden Cove high performance computing core and the Gracemont high efficiency core, and the goal of this chip is to offer a ‘Performance Hybrid’ option into the portfolio. Raja explained to the audience that the company has learned a lot due to building Lakefield, its current hybrid x86 chip for thin and light notebooks, and while Lakefield was focused on battery life, Alder Lake will focus instead on performance.
Alder Lake will involve Intel’s next generation hardware scheduler, which we are told will be able to leverage all cores for performance and make it seamless to any software package. Intel claims that Alder Lake will be Intel’s best (ever? 2021?) performance-per-watt processor.
If leaks are to be believed, then Alder Lake looks set to offer an 8+8 design, although that has not been confirmed. Intel did not go into detail if Alder Lake will involve any next generation packaging, such as Foveros (which Lakefield does) – but in the Q2 2020 financial disclosures, it was said to be positioned for mobile and desktops. We expect Intel to discuss Golden Cove and Gracemont at some point next year, and then Alder Lake as an extension to those – we have already seen Intel documents regarding new instructions for each of these cores. My prediction is to come back this time next year, where we should have more to talk about.

Meteor2 - Monday, August 17, 2020 - linkNonsense.
Spunjji - Monday, August 17, 2020 - linkI'm glad that people finally care about iGPU performance now that Intel are about to get better than AMD at it. 😏
I do find their choices in that area inexplicable. Renoir having Vega makes some sense; Cezanne on the other hand...
If Tiger launches on time, in volume and hits its performance metrics then it should be a force to be reckoned with. I very much doubt we'll ever see it on desktop, though, and my understanding is that the 8-core parts will be arriving significantly later than the 4-core ones.
FXi - Sunday, August 16, 2020 - linkYep the "confirmed" or "scheduled for date xxx" statements from Intel have been useless for several years. Sooner or later the newsworthy world will just start ignoring their official statements entirely as baseless rumor. They simply cannot deliver anything when they think they will 6 months ahead of time let alone a year or more. They are even less accurate than weather forecasters.
Meteor2 - Monday, August 17, 2020 - linkWell given the way people hang onto every last word of rumour, I don't see them ignoring official Intel statements any time soon.
YB1064 - Monday, August 17, 2020 - linkAT should stop publishing these vaporware slide decks.
liujustin604 - Thursday, September 24, 2020 - linkOh wait, Tiger Lake is Laptop.
tipoo - Friday, August 14, 2020 - linkHmm, does the hardware scheduler alleviate concerns over Windows not handling this well?
nandnandnand - Friday, August 14, 2020 - linkLakefield was the "beta test" of x86 big/small, hopefully. Or it just wasn't capable of much because of power constraints.
Santoval - Saturday, August 15, 2020 - linkIt's both actually.
Spunjji - Monday, August 17, 2020 - linkPrecisely that.
I'm still confused by why Intel chose to beta-test several new technologies simultaneously (mixed cores, chiplets, stacking) on what's effectively a low-end chip. I gather they're relying on marketing to keep the prices high, but we won't know until we actually see it, and now they're talking about it like it's a thing that already happened...
