Intel clearly told that Tigerlake supports DDR4 and LPDDR4 initially. A later version could support LPDDR5. The point is that the hardware itself supports LPDDR5 but Intel dropped it.
This is what AT's article says:
Asked what enthusiasts should be excited about in the future with Intel, he replied:
"Alderlake – it was only a small part of our Architecture Day event, but it’s the biggest architecture movement since the Core architecture in 2006. It’s a huge leap and will be very exciting.
We haven’t always delivered content creator-level performance, or at the very least you would have to choose between one platform and another, but with Alder Lake and hybrid technology, you can get both great gaming performance and content creation performance at the same time.

That directly contradicts what Anandtech said about it.
And when I actually see bench,arks, real, not Intel benchmarks, then I may be impressed.About Alder Lake:

There are numerous ones for GB5 and a few other benchmarks, sure it isn’t much, but one thing is for sure, Intel isn’t out of the race yet. Tiger Lake clearly walks all over Zen 2. I hope that Tiger Lake pushes AMD to release mobile parts faster, but I worry that with Intel beginning to spin up 10nm, AMD is going to get hit hard. Zen 3 should have launched a few months ago, but I understand why they couldn’t. 7nm supply is beating them up right now.
Luckily I don’t see Intel pulling another Core architecture on them. However, when Intel ends up moving to 10nm for most of it’s products, AMD will have a damn near vertical battle ahead.
EDIT: Part of the the issue is that mobile (15W) Tiger Lake appears to soundly beat Zen 2. While Zen 3 will improve things, that puts them neck-in-neck.
He linked a Windows result for TGL but a Linux result for Renoir - the two aren't comparable.Lets wait and see power consumption for those 15w 4.7ghz parts. normalised to clock Zen2 and tigerlake in the benchmark you linked for ST are pretty close per clock ( tigerlake wins ~7%). On my Lenovo Slim5 the 4700u on the single thread parts doesn't even touch 10watts package power peak. What would Renoir look like with the SMU allowing ~20 watt single core burst ~4.7ghz clock? probably pretty damn close to tigerlake wouldn't you say..............
AMD has so much room to move with Zen2 let alone Zen3 in terms of mobile SKU configuration if they choose to match the way intel 10/14nm currently consumes power.
Rumor is that it guzzles power. The burst ST performance is impressive and so is the vast improvement over ICL in general, but I want to see sustained clocks in MT workloads at reasonable wattages. These GB results are nice and all, but there's more to a laptop CPU.Lets wait and see power consumption for those 15w 4.7ghz parts.
It won't, not at all.Golden Cove will have to convincingly beat Zen 4 on per-core performance to be competitive since Zen 4 will definitely have core count advantage. It will be interesting if that actually happens.
It has, Cezanne is coming relatively soon after TGL.I hope that Tiger Lake pushes AMD to release mobile parts faster
Extensive, independent benchmarks are the way to go. Marketing benchmarks are pretty unreliable.These are tactics to bring doubt to peoples minds so not to buy AMD. Very good PR. I'll wait for the real benchmarks and see what to buy next year.

TGL is definitely the better laptop CPU for most people.Extensive, independent benchmarks are the way to go. Marketing benchmarks are pretty unreliable.
That said, I think a Tiger Lake / Ryzen 4000 face-off would be pretty interesting. My money is on Ryzen 4000 edging ahead.
Intel said that with Tigerlake, they did not focus on IPC improvements (i.e. larger ROB etc.) . Instead I think they focused on making it more efficient (even without better transistors) by overhauling everything. (i.e. what is normally called "CDyn optimization" by the designers). I.e. the circuit blocks get optimized so the core runs cooler at the same voltage.

Tiger Lake U has a TDP of 15W and a base clock of 2.7 Ghz. That is much higher than Renoir, so it is clearly a more efficient chip. This isn’t 14nm.
4C/8T vs 8C/16T?That is much higher than Renoir, so it is clearly a more efficient chip. This isn’t 14nm.

Well, modern power gating is pretty advanced, but is it really fair to compare a quad core and octo core die?
In an ideal world, AMD would have to budget and volumes to have actually made quad core Renoir if for no other reason than to keep Shivansps happy on the Renoir thread, but we have what we have.
However, in terms of marketing 8C vs 4C would be hard sell even if the quad has a bit more ST performance. It is no longer Construction Core Vs Intel Core after all.
Tigerlake and 10nm SF greatly improves V/F curves:
-Tigerlake's Willow Cove can operate at 2.6GHz in the same voltage as Sunny Cove at 1.6GHz.
-3.6GHz in the same voltage as SNC at 2.6GHz.
-4.6GHz in the same voltage as SNC at 3.9GHz.
-Finally, it can go even higher with higher voltages.
Sunny Cove at 15W runs at 1.8-2GHz with MT workloads and 2.4-2.6GHz at 25W.

The 2.7 base is at 25 or 28 W.
Do you have a source? Not that it matters much, however AnandTech says: “The current processor we know about today is a four core processor at 15 watts.”
