PTT leaked some juicy details of the upcoming Intel "Rocket Lake" and "Alder Lake" processor generations. "Rocket Lake" will power Intel's 11th generation Core processor series in the LGA1200 package, and are rumored to be a "back port" of Intel's advanced "Willow Cove" CPU cores to a 14 nm-class silicon fabrication node, with core-counts ranging up to 8. The idea for Intel is to sell high IPC, high clock-speed desktop processors for gaming.

According to the PTT report, there will be three kinds of SKUs for "Rocket Lake" based on TDP: 8-core parts with 95 W TDP rating; and 8-core, 6-core, and 4-core parts in 80 W TDP and 65 W TDP variants. For the 95 W (PL1) parts, the power-levels PL2, and PL4 are reportedly set at 173 W and 251 W, respectively, and a 56-second Tau (a timing variable that dictates how long a processor can stick around at an elevated power-state before retreating to PL1, which is interchangeable with the TDP value on the box). The 80 W TDP parts feature 146 W PL2, 191 W PL3, and 251 W PL4, but a lower Tau value of 28 seconds. For the 65 W parts, the PL2 is 128 W, PL3 is 177 W, and PL4 251 W, and the Tau value 28 seconds.



The report also points to the high likelihood of Intel's upcoming LGA1700 socket, on which "Alder Lake" debuts, to feature DDR5 memory interface. According to @Chiakokhua (The Retired Engineer), interpreting the PTT report, "Alder Lake-S" can reportedly handle DDR5 at 4800 GT/s (reference), with one 1DPC (one DIMM per channel, interchangeable with one single-rank DIMM per channel). With 2DPC (two DIMMs per channel or one dual-rank DIMM per channel), the memory controllers can only handle data rates of up to 4000 GT/s reference. Overclocking will be possible in both cases. At least 6 PCB layers will become a practical necessity for motherboard designers to have typical 2DPC-capable setups (four DIMM slots).

Keep in mind that PTT is a Taiwanese "gossip" BBS on the web, so I would take anything coming from there with the suitable amount of salt.

I want to see maximum Wattage as power consumption on the retail boxes so consumers now how much they are getting ripped off.
Advertising a TDP based on average before boost is lying to the public.

Okay Intel, lets calm down with the 14nm shit and get on with it in 10nm or 7nm

Hope there are fewer smart gamers out there who are going to buy Intel 10th Gen processors to that the motherboards manufacturers will learn a lesson.

So if i5-11600k is 6c/6t again, it still needs to be faster than 6c/12t 10600k in multithreading...backported Willow Cove put to test

I'm honestly confused with all those Intel's lakes. I don't know what's current, what's next gen, what follows. iX-10000 is considered 10th gen, but also iX-1000GX is considered 10th gen too. They are all 14nm+++ but there are some parts named iX-8000 that are 10nm. So much confusion and so much effort to find out what each model actually is....

Everyone is. It was confusing due to the sheer similarity of the code names even before their process node improvements came to a halt and we suddenly had "generations" with no real differentiator beyond launch date. Now it's utter chaos.

I dont think there are any relevant 8th gen 10nm chips though - there was that one low-volume one (i3-8121U) that shipped in like two China-only laptops with Radeon RX 540 graphics due to the iGPU being defective (so that Intel could avoid shareholder lawsuits after promising 10nm would "ship for revenue" in 2018 or something). 8th gen for all intents and purposes was 14nm only.

10th gen is a mix of 14nm (ix-10xxx) Skylake architecture (I believe the latest tweak of this is Comet Lake? See, I can't keep them straight either.) and 10nm Ice Lake architecture (ix-10xxGx) chips. Ice Lake is only in the U and Y series, i.e. low power (the fastest are the 28W chips in the MBP 13"). Everything else is still a Skylake derivative. Ice Lake has ~18% higher IPC than Skylake/CML chips, but doesn't clock nearly as high. They also stop at 4c for U-series vs. 6 cores in the CML series, so the older tech is actually faster overall. Ice Lake chips have a much better iGPU though, coming reasonably close to AMD's latest in its G7 configuration. So in general, for Intel 10th gen you have to choose between CPU or GPU performance in mobile, while in H- (high end mobile) or S-series (desktop) chips you get yet another slightly faster Skylake derivative.

The upcoming Rocket Lake chips are reportedly a back-port of the Ice Lake cores (or possibly their successor) onto 14nm for desktop use. The IPC increase is desperately needed there, but how high they will clock is an open question - Intel needed 5 generations to make Skylake clock as high as it does today, so I don't expect Rocket Lake to go quite that high even if the 14nm process is highly optimized for high clocks.

Tech sites got trolled again! Why would Intel go backwards and introduce less cores in 2 years time? At that point AMD is likely going to be at 24 cores for desktop or more.

Because these aren't Skylake cores, and 8 is likely how high they can go before the die becomes unreasonably large on 14nm. If AMD was still on 14nm they definitely wouldn't have 16-core MSDT CPUs. Intel needs to get 10nm working properly in high volumes at high clocks with relatively large die sizes to be able to keep up; until then everything else is just treading water at best.

I've officially stopped giving a shit about anything with the Intel logo in it.

You just know its not going anywhere anytime soon. Waste of time and effort trying to decipher their codename language. Stick it where the sun don't shine, thx. This company is now safely and definitively relegated to the mindshare graveyard, where dead FX processors lay buried. Funny how things change.

Hmmm, next upgrade from Coffee Lake?

CML? still 14nm. Same architecture. Still PCIe 3.0. No new ST performance beyond stock speeds

RKL? still 14nm. +20% ST performance, but oh that heat on the same node. Mature ddr4 speeds, maybe 5200Mhz-5400Mhz? Last monolithic Intel CPU. Last Intel fast ring bus. PCIe 4.0. 20CPU lanes (4 more). Thunderbolt 4 (USB4 compliant)

ADL? 10nm. Another small increase in ST performance. 8+8 mesh bus latency? I dunno Dr. Frankenstein jumbled chip? DDR5 speeds low/latency high at infancy? PCIe 4.0

MTL? 7nm running cooler. Increased +15-20% ST performance. PCIe 4.0. DDR5 more mature.

I dunno what to do. :oops:

There's one thing which should be commended, they could run 14nm since it's dawn to date when the competition is at 7nm + EUV. And the uArch since 5 years, just epic. Wonder what did those damn engineers think, historic achievement alongside their historic failure of 10nm. And the insane confusion. I just hope whatever Lake it's not a stupid Big+Little garbage with dynamic clock scaling for Desktop S parts rather I'd like to see that relegated to a thin and light notebook BGA trash part and Desktop parts get high speed cores which we can control and what about Ring Bus and Clock speeds ? Those are the biggest advantages that Intel has got and the biggest lockup was the DMI link speed. I hope with Rocket Lake we do not have that DMI saturation at 3.0 anymore ? but what about Z490, will it have new DMI link speed ? So many questions and the elephant in the room, heat.

I just want to build a super fast PC with 1080P 240Hz Display for best gaming, esp the old games since I don't have any interest in the new games when they want to shoehorn all the polticial trash into them and kill them like - Wolfenstien, Mass Effect, Gears of War etc.

Is Jim Keller working on designing Intel CPU's or is he in basically a managerial role, where he is essentially just managing the teams, not actually developing the architecture? He has been working for Intel for 2 years now, it'd be interesting to see what has come out of it.

it takes way more than 2 years to create a new uArch and make it to end users

Welcome to Intel's expected drought.
I wanted to at least double my core count, I didn't wait 9 years to buy another 4 Core 8 thread CPU! (thanks Intel)
Whatever I get I'm going to be blown away. Especially with that 3080. It's been a long time coming.
If I can hold on I think your Coffee lake can too. : )
