Intel’s Eleventh-gen Rocket Lake-S is the primary main rework of the corporate’s desktop pc cores for the reason that Sixth-gen Skylake CPU in 2015, and arguably the most important 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 almost weekly efficiency leaks. Most lately, 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 every part you might want to know. You may also bounce to a subject space utilizing the useful record under:

What’s Intel Eleventh-gen Rocket Lake?
Rocket Lake is an attention-grabbing 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 Tenth-gen Ice Lake laptop computer chips. For graphics, Intel makes use of the Xe cores from its Eleventh-gen Tiger Lake laptop computer CPUs, in addition to Tiger Lake’s extra superior media engine, which may decode next-gen codecs akin to AV1.
Why is Rocket Lake constructed on the ‘historic’ 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 alternative that permit it push the design to greater speeds, however that’s most likely extra spin than actuality. Extra probably the corporate simply doesn’t have the capability to construct each chip on a 10nm course of at this time. Principally, when life provides you lemons, you make Rocket Lake.
Why does the Eleventh-gen Core i9 have fewer cores?
While 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 Eleventh-gen desktop chips merely can’t match 10 cores onto the die area together with the brand new graphics cores. Which means the Eleventh-gen Core i9-11900K will max out at 8 cores, whereas the older Tenth-gen Core i9-10900K has 10 cores.
What are the speeds and feeds?
In the event you doubt Eleventh-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’ll vary from lower-power 6-core Core i7-11400T with a lift clock of 3.7GHz, to the 8-core Core i9-11900K chip, with a 5.3GHz prime 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 under, this doesn’t appear 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 value vary, Intel can be releasing a lineup of “refreshed” Tenth-gen chips, starting from 2-core Pentium Gold chips to 4-core Core i3 CPUs. All of them will characteristic Hyper-Threading.
Wish to purchase Intel Eleventh-gen Rocket Lake?
Is Rocket Lake value it?
There’s an previous saying that there are not any dangerous merchandise, simply badly priced merchandise. How Rocket Lake shall be acquired will largely rely upon how a lot it prices and the way properly it does towards AMD’s comparable chips in addition to the way it does towards Intel’s older Tenth gen chips too.
Trying on the prime canine Core i9-11900K at $539, it is priced about $51 greater than the chip it would substitute, the Core i9-10900K, however extra importantly it is truly solely barely cheaper than AMD’s 12-core Ryzen 9 5900X which has a value of $549.
Whereas we’ve not examined the Core i9-11900K, we’re nearly sure the Ryzen 9 5900X ought to overpower it in multi-threaded duties and doubtless match or beat it in most lightly-threaded duties too. Sport over? Probably not. One large drawback AMD has had is holding 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 seems to be to compete very properly with the brand new Core i9 and is in inventory lately, we do not understand how lengthy that’ll final.
In the event you’re Tenth gen vs. Eleventh gen, we predict those that need PCIe 4.0 and use superior AVX-512 options plus different enhancements the chip has could make it well worth the small premium. These on a tighter price range although and actually “simply play video games” shall be pleased going with the very best priced chip.
When can I purchase Eleventh-gen Rocket Lake CPUs?
The formal launch date for Rocket Lake is March 30. Whereas Intel mentioned it believes it would have ample 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 Eleventh-gen Rocket Lake carry out?
Doesn’t having solely 8 cores imply it’s slower?
There’ll certainly be some duties the place the older Tenth-gen, 10-core Core i9 flagship CPU outperforms the newer Eleventh-gen, 8-core Core i9 flagship. However there can even be some duties, even multi-threaded ones, the place the brand new era will prevail, particularly with its improved effectivity.
What does ‘improved effectivity’ imply?
With the newer Cypress Cove cores, Intel is claiming a 19-percent enhance in IPC, or Directions Per Cycle (or Clock). At the next stage, that principally means the brand new chip will be 19 % extra environment friendly on the process. We are saying “can,” as a result of IPC and effectivity measurements don’t at all times assure you will note that achieve, however you’ll usually see one thing near it.
Is Eleventh-gen Rocket Lake sooner than Ryzen 5000?
It’s no shock that Intel’s Eleventh-gen chip is predicted to be sooner than its Tenth-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 % sooner on PCIe 4.0 efficiency than Ryzen. At CES Intel additionally confirmed off seven video games the place it says the Core i9-11900K outpaces the Ryzen 9 5900X.
Intel’s newest inside checks 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 Eleventh-gen Rocket Lake half to be as quick or sooner than AMD’s Ryzen 5000 chips.
Preserve studying for extra on efficiency, reminiscence, and different highlights.
