Intel 12th Generation Alder Lake Platform Reportedly Brings 20% Single-Threaded Performance Uplift
Intel only just announced their 11th generation Rocket Lake-S desktop processors last week but we are already receiving information about the next generation Alder Lake-S platform which will finally make the jump to 10 nm. Intel slides for the upcoming family of processors have been leaked and they reveal some interesting information including a claimed 20% single-threaded performance increases from the new Golden Cove core design and 10 nm SuperFin node. The processors will feature Intel Hybrid Technology with a mix of small low-performance cores and large high-performance cores with a maximum of eight each for sixteen total cores. The processors will also include the latest connectivity with both PCIe 4.0 and PCIe 5.0 support along with DDR4 and DDR5 4800 MHz compatibility.
Intel will also be launching a new socket type called LGA1700 with a new package size which will render existing cooling solutions for LGA115X and LGA1200 sockets incompatible. The processors will also come with the launch of a new 600 Series chipset with PCIe 3.0 and PCIe 4.0 support along with the usual complement of USB, SATA, and networking. The entry-level 600-series motherboards will only support DDR4 memory at up to 3200 MHz while high-end Z690 motherboards will include DDR5 support. Intel has confirmed that they intend to launch Alder Lake later this year but it is yet to be known if they are referring to the desktop or mobile series.

It was purely about the concept of a core in a cpu, what a core is, what can be called a core.
And tbh, Im not sure that was rightly settled/decided, regardless if it was AMD or any other company.
For single core performance Anandtech tests show 11700K score improvement over 10700K +15.5% in SPECint2017 and +19.6% in SPECfp2017. This is with a frequency deficit, Anandtech calculates IPC improvement as +18.5% and +22% respectively.
Multicore results suffers badly, +5.8% and +16.2%. They did not specify the frequencies there but it is probably safe to say Rocket Lake runs at lower frequency.
For comparison - with Zen3 over Zen2, Anandtech found +19% in the same SPEC2017 for single core and +8-9% for multicore.
In our testing, we saw the following:
- Single thread floating point: +19.0%
- Multi-thread floating point: +19.5%
Sounds great, right?- Single thread integer: +13.0%
- Multi-thread integer: +7.3%
Just a reminder those are estimates as SPEC scores have to be submitted for validation(?) & Andrei hasn't done that AFAIK.Tiger Lake is finally clocked high enough for it to impress, but 8 months in and there is still n sign of Tiger Lake 8-core. They promised Q1 of this year, but obviously missed it.

The hopeful idiots will continue to believe Intel BS marketing machine, that somehow Intel will magically launch 4x as many cores as they are current;y shipping in consumer 10nm parts, combined with 2 completely new architectures! Meanwhile here in reality, you won't even be able to buy Rocket Lake in retail until sometime in May!
You'll be lucky to see Alder Lake shipping before May of next year.

Up to 20% ST performance means exactly what it says, that's the best case scenario, but says nothing about the average or the minimum improvements.
There is a huge difference in up to 20% better performance and 20% better average performance. Take for instance Rocket Lake's 19% IPC gain; IPC is average instructions per clock, so this doesn't mean that every workload will get a 19% gain, the worst get ~0% performance gains, the best ~40% performance gains. So Rocket Lake has 19% better IPC but up to 40% better performance per clock. So if this claim of "up to 20% better ST performance" for Alder Lake is accurate, it probably means the average is much lower, and would make it a fairly small generational upgrade.
But keep in mind these claims are probably bogus. No one, even at Intel, does know the clock speeds until the final stepping has gone through testing. So at this point Intel only have performance targets, not precise performance figures for specific models.20% faster AVX-512 is unlikely. While it probably will be a few percent faster due to less throttling on 10nm, a larger improvement like an extra FMA set would yield much higher maximum performance than that, and in such cases they would surely boast about "up to 50% higher performance", not 20%.
It was an odd design but it was supposed to crush Intel i7s SMT integer performance and concede floating point but ended up barely being able to compete in integer. It was a big expensive core and AMD was swinging for the fences and struck out; they even had 16 core Opterons. You don't have to feel sad for them it was bad design, but Intel has much longer track record of bullshit marketing not to mention their market manipulation.
New engineers and CEO won’t fix 2019/20 and 21 embarrassments.
2022 is Intel’s year to win/lose.
All 14nm and 10nm designs will lead to a surplus and more market loss to AMD.

Hate seeing the King stumble over and over.
intel definitely need a performance uplift
But yeah, assuming that someone can’t write english and it’s a typo of sorts, you are correct in that up to 20% improvement means jack and shit without specifics.
As opposed to PCIe 4.0 gear back in 2019 or even 2018 end.Can't have PCIe 5.0 without 4.0 ever being released, it was delayed a lot for a number of reasons & that's why the relative overlap with v5 though v6 is totally useless as of now!
And i'm not sure you will even see PCIe 5.0 devices this year, so totally agreed with you.
They likely wanted to release a new socket and PCI-E gen every ~2 years to justify a new platform and then got stuck with skylake++++ and waited and waited
