Intel’s 11th-gen Rocket Lake-S is the primary main rework of the corporate’s desktop pc cores because the Sixth-gen Skylake CPU in 2015, and arguably the largest step ahead in years.
It’s additionally one of many least-secret chips in latest reminiscence. Unofficial info began trickling out proper after it was launched at digital CES in January, adopted by practically weekly efficiency leaks. Most not too long ago, a retailer in Germany accidentally started selling the CPUs a month earlier than its official launch, engendering a spate of early, unauthorized reviews and even a delidding to look at the cores.
There’s loads to maintain up with, so we’ll break down the whole lot you might want to know. You may as well soar to a subject space utilizing the helpful record beneath:
- Why is Rocket Lake constructed on the ‘historical’ 14nm course of?
- Why does the 11th-gen Core i9 have fewer cores?
- What are the speeds and feeds?
- How a lot do Rocket Lake CPUs value?
- When can I purchase Rocket Lake?
- Doesn’t having solely Eight cores imply it’s slower?
- What does ‘improved effectivity’ imply?

- Is Rocket Lake quicker than Ryzen solely in video games?
- Ought to I consider these efficiency numbers?
- However wasn’t 11th-gen Rocket Lake already reviewed?
- Ought to I care about AVX512 assist?
- Reminiscence could matter extra with Rocket Lake
- The very best gear is barely on Core i9
- Actual-time reminiscence overclocking
- You’ll be able to overclock RAM on cheaper motherboards
- Any Rocket Lake CPU helps reminiscence overclocking

- Rocket Lake’s 500 chipsets assist wider DMI 3.0
What’s Intel 11th-gen Rocket Lake?
Rocket Lake is an fascinating mashup of various CPUs and applied sciences Intel has amassed. It’s constructed on Intel’s 14nm course of, utilizing cores Intel calls Cypress Cove. Cypress Cove cores are primarily based on the 10nm Sunny Cove cores from Intel’s 10th-gen Ice Lake laptop computer chips. For graphics, Intel makes use of the Xe cores from its 11th-gen Tiger Lake laptop computer CPUs, in addition to Tiger Lake’s extra superior media engine, which might decode next-gen codecs resembling AV1.
Why is Rocket Lake constructed on the ‘historical’ 14nm course of?
Though primarily based on CPU and GPU architectures that have been initially constructed on the extra superior 10nm and 10nm+ Enhanced Finfet manufacturing processes, Intel nonetheless determined to construct Rocket Lake on its older 14nm course of.
Intel likes to say this was a selection that permit it push the design to increased speeds, however that’s most likely extra spin than actuality. Extra seemingly the corporate simply doesn’t have the capability to construct each chip on a 10nm course of in the present day. Mainly, when life offers you lemons, you make Rocket Lake.
Why does the 11th-gen Core i9 have fewer cores?
If you take CPU and GPU cores initially designed for a a lot denser 10nm course of after which blow them as much as match on the less-dense 14nm course of, they’re going to take up extra space. That’s why the 11th-gen desktop chips merely can’t match 10 cores onto the die house together with the brand new graphics cores. Meaning the 11th-gen Core i9-11900Ok will max out at Eight cores, whereas the older 10th-gen Core i9-10900Ok has 10 cores.
What are the speeds and feeds?
In the event you doubt 11th-gen Rocket Lake will see widespread adoption, Intel’s launch plan suggests in any other case, with a reasonably deep record of 18 completely different chips. They are going to vary from lower-power 6-core Core i7-11400T with a lift clock of 3.7GHz, to the 8-core Core i9-11900Ok chip, with a 5.3GHz high clock and all-core clock of 4.8GHz.
We don’t know in the event that they’ll all hit on the identical day, however primarily based on the slides beneath, this doesn’t seem like a restricted launch.
The mid-range of Intel’s new Rocket Lake Core i5 chips are all 6-core chips with Hyper-Threading enabled.
For these within the budget-friendly worth vary, Intel can also be releasing a lineup of “refreshed” 10th-gen chips, starting from 2-core Pentium Gold chips to 4-core Core i3 CPUs. All of them will characteristic Hyper-Threading.
Need to purchase Intel 11th-gen Rocket Lake?
Is Rocket Lake value it?
There’s an outdated saying that there are not any dangerous merchandise, simply badly priced merchandise. How Rocket Lake will probably be obtained will largely depend upon how a lot it prices and the way effectively it does towards AMD’s comparable chips in addition to the way it does towards Intel’s older 10th gen chips too.
Trying on the high canine Core i9-11900Ok at $539, it is priced about $51 greater than the chip it would exchange, the Core i9-10900Ok, however extra importantly it is truly solely barely cheaper than AMD’s 12-core Ryzen 9 5900X which has a worth of $549.
Whereas we’ve not examined the Core i9-11900Ok, we’re nearly sure the Ryzen 9 5900X ought to overpower it in multi-threaded duties and possibly match or beat it in most lightly-threaded duties too. Recreation over? Probably not. One enormous downside AMD has had is retaining the Ryzen 9’s in inventory making the worth of a Ryzen 9 5900X nearer to $900 more often than not. Whereas the Ryzen 7 5800X appears to compete very effectively with the brand new Core i9 and is in inventory today, we do not know the way lengthy that’ll final.
In the event you’re 10th gen vs. 11th gen, we predict those that need PCIe 4.Zero and use superior AVX-512 options plus different enhancements the chip has could make it definitely worth the small premium. These on a tighter funds although and actually “simply play video games” will probably be completely satisfied going with the most effective priced chip.
When can I purchase 11th-gen Rocket Lake CPUs?
The formal launch date for Rocket Lake is March 30. Whereas Intel mentioned it believes it would have enough portions, anybody who has tried to purchase a Ryzen 5000 CPU is aware of simply how loopy it has been to attempt to purchase a brand new CPU.
How does 11th-gen Rocket Lake carry out?
Doesn’t having solely Eight cores imply it’s slower?
There’ll certainly be some duties the place the older 10th-gen, 10-core Core i9 flagship CPU outperforms the newer 11th-gen, 8-core Core i9 flagship. However there will even be some duties, even multi-threaded ones, the place the brand new technology will prevail, particularly with its improved effectivity.
What does ‘improved effectivity’ imply?
With the newer Cypress Cove cores, Intel is claiming a 19-percent improve in IPC, or Directions Per Cycle (or Clock). At a better stage, that mainly means the brand new chip could be 19 p.c extra environment friendly on the activity. We are saying “can,” as a result of IPC and effectivity measurements don’t all the time assure you will notice that acquire, however you’ll typically see one thing near it.
Is 11th-gen Rocket Lake quicker than Ryzen 5000?
It’s no shock that Intel’s 11th-gen chip is anticipated to be quicker than its 10th-gen chip, however what about AMD and its Ryzen 5000-series chips? Intel has claimed two areas of superiority: gaming performance and storage performance.
Intel mentioned in head-to-head testing, Rocket Lake is about 11 p.c quicker on PCIe 4.Zero efficiency than Ryzen. At CES Intel additionally confirmed off seven video games the place it says the Core i9-11900Ok outpaces the Ryzen 9 5900X.
Intel’s newest inside assessments give Rocket Lake a 3-percent to 11-percent lead towards AMD’s Ryzen 9 5900X in gaming. Total, Intel appears to be relying on the brand new 11th-gen Rocket Lake half to be as quick or quicker than AMD’s Ryzen 5000 chips.
