Intel opened its Intel Innovation convention Tuesday by lastly unveiling what everybody has been ready for: how briskly its new 12th-gen “Alder Lake” desktop Core chips might be, and the way a lot they’ll price. The flagship, the Intel Core i9-12900Okay, would be the “world’s best gaming processor,” Intel executives stated; it is going to be priced $50 increased than the last-gen Core i9-11900Okay at launch, too.
Perhaps not surprisingly, there received’t be that a lot selection to Intel’s first “performance hybrid” processors: simply six new chips, which received’t even embody a Core i3 processor. By distinction, Intel launched 19 new 11th-gen “Rocket Lake-S” processors again in March, which is able to conceivably fill any gaps in Intel’s 12th-gen portfolio.
(At the Intel Innovation occasion held Wednesday in San Francisco, Gregory Bryant, govt vice chairman and basic supervisor of the Client Computing Group, stated that there finally be 60 new processors within the Alder Lake household.. Bryant stated that Intel is at the moment delivery 28 variations of Alder Lake to PC makers.)
Alder Lake does have some surprising twists. For one, Intel launched information displaying that Alder Lake can considerably outperform an earlier 11th-gen Rocket Lake chip when duties are run concurrently, somewhat than one after the opposite. Alder Lake’s help for sooner, pricier DDR5 has been recognized, however a brand new dynamic XMP reminiscence overclocking characteristic provides an unexpected twist. Intel has additionally added easy overclocking: click on a software program management, and also you’ll get a whole lot of extra megahertz totally free.
Here are Intel’s new Alder Lake chips
As we described in August, Intel’s Alder Lake chips now embody two various kinds of cores: quick “performance cores,” and slower, much less power-hungry, “efficiency” cores. Within the six new Alder Lake chips, the efficiency cores will run from a base velocity of 3.2GHz on up 3.7GHz, with turbo speeds topping out at 5.2GHz. That’s only a tick slower than the 5.3GHz that the Core i9-11900Okay achieved.
Even summarizing the six new processors now presents way more of a problem than earlier than, although we’re boiling it down to simply three. Each of the “K” variants listed under contains the brand new built-in UHD Graphics 770 GPU. For every, a separate “KF” variant cuts out the GPU in favor of a discrete GPU, bought individually. (Incidentally, Intel didn’t point out its discrete Intel Arc GPU, scheduled for an early 2022 launch.) Each of the brand new chips seems to be costlier than the launch costs of their 11th-gen Rocket Lake counterparts, with extra of a premium on the high-end processors.
- Core i9-12900Okay: 16 cores/24 threads (8 efficiency cores at 3.2GHz (base)/5.2GHz (turbo), 8 effectivity cores at 2.4GHz (base)/3.9GHz (turbo))
- Core i7-12700Okay: 12 cores/20 threads (8 efficiency cores at 3.6GHz/5.0GHz, 4 effectivity cores at 2.7GHz/3.8GHz)
- Core i5-12600Okay: 10 cores/16 threads (6 efficiency cores at 3.7GHz/4.9GHz, 4 effectivity cores at 2.8GHz/3.6GHz)
Intel
Interestingly, the “slower” Alder Lake chips will run at increased base clock speeds than their costlier, higher-performance counterparts. These cheaper chips supply much less of a differential between the bottom clocks and the sooner turbo speeds. Unfortunately, Intel isn’t providing an all-performance-core Alder Lake because it hinted earlier.
You ought to observe, too, that whereas these are all technically 125W chips, Intel has tossed out the time period “thermal design power (TDP)” in favor of “processor base power (PBP).” And that has a caveat, too. Though the PBP on all of those is 125W, PC coolers might want to account for a “maximum turbo power”: the Core i5-12600Okay/KF’s turbo energy is 150W, the Core i7-12700Okay/KF max turbo energy is 190W, and the Core i9-12900Okay/KF is 241W. All are manufactured on Intel’s Intel 7 course of know-how.
As you would possibly count on, Intel is launching the desktop variations of its 12th-gen Alder Lake chips first. Mandy Mock, Intel’s vice chairman and basic supervisor of the desktop, workstation, and channel group inside Intel, stated that Intel’s companions will help the launch of Alder Lake with 60 completely different motherboards.
About 140 clients will ship 12th-gen-powered PCs by the top of the yr, she added, with over 100 new desktop designs from all-in-ones to small-form-factor PCs to debut in 2022. That’s the identical timeframe as cell and ultramobile (pill) variations are anticipated to reach, most likely round when the CES convention opens in January 2022. According to Bryant, PC makers will obtain the cell variations of Alder Lake subsequent month.
Performance, with a watch towards multitasking
Intel informed us in August that we must always count on an total 19 % gen-over-gen enchancment with the 12th-gen Alder Lake versus the 11th-gen Rocket Lake chips, and that also holds true. Now, nonetheless, we now have some extra specifics.
In phrases of the Alder Lake efficiency core, Intel is now saying that the 12th-gen Alder Lake efficiency core is 28 % sooner than the 10th-gen Comet Lake-S processor, and that the 11th-gen Rocket Lake-S chip was 12 % sooner than Comet Lake. Applying somewhat math, that implies that the 12th-gen Alder Lake’s P-core is 14 % sooner than the 11th-gen Rocket Lake-S.
Intel
Marcus Kennedy, the final supervisor of Intel’s gaming, creator, and e-sports phase, additionally reiterated that the 12th-gen Alder Lake “efficiency” core is about 40 % sooner than Intel’s sixth-generation Core, Skylake. The 12th-gen Alder Lake’s E-core is about 1 % sooner than the 10th-gen Comet Lake, or a few 10 % dip in efficiency from the 11th-gen Rocket Lake-S.
PC makers, in fact, have the choice to run Alder Lake at decrease energy ranges. Guy Therien, an Intel fellow, famous that the Core i9-12900Okay will be run at 65W, and nonetheless ship the efficiency of the Core i9-11900Okay at 250W. That’s a large energy financial savings, particularly when future cell processors come into play.
Intel
What’s new on the efficiency entrance are two issues: First, Intel usually supplies way more element about how briskly the processor runs in particular video games at launch, and it did so as we speak in comparisons to its present 11th-gen processor in addition to AMD’s desktop processor from final yr, the Ryzen 5950X. Second—an concept which Intel has been speaking about for a while—is that Alder Lake might be a processor whose efficiency and effectivity cores might be significantly suited to working simultaneous duties.
In all of its gaming comparisons, Intel used a system primarily based on DDR5 reminiscence, the brand new, sooner reminiscence kind that accompanies the Alder Lake technology. The different methods used DDR4. It seems that Intel’s take a look at PC used a PCIe 4 SSD, nonetheless. All gaming comparisons used an RTX 3090 at 1080p High settings. We’ve listed a couple of of Intel’s comparisons under.

Incidentally, Intel examined the Ryzen 5950X earlier than a bug cropped up with Windows 11 and the 5950X’s cache latency. Intel’s Kennedy stated that Intel would retest its chips and re-release the outcomes sooner or later.
Remember, too, that the efficiency of Alder Lake is managed by a brand new {hardware} know-how known as Thread Director, designed to work with, and already built-in into, Windows 11. Thread Director analyzes the efficiency wants of every thread, assigning them to the best kind of core—after which re-assigning them on the fly if new threads seem. Essentially, the chip itself conveys the effectivity of sure cores to the working system through an API. The OS then makes the choices on which cores and instruction threads to make use of. Thread Director makes use of a mannequin that’s been skilled by AI to establish the workload lessons, Therien stated.
In Windows 11, Thread Director will make “better decisions on where to put certain kinds of work,” Therien stated, which is able to allow better efficiency. But in Windows 10 and Linux, Thread Director will nonetheless run, however with out a number of the thread-specific suggestions that may enhance efficiency inside Windows 11. The total expertise is “still very great,” he added.
All of those components add a brand new wrinkle to the 12th-gen Alder Lake chips: Intel believes that your PC might be sooner when two duties are run concurrently, somewhat than one after one other. That’s a sea change from the previous manner of computing, while you’d run one job, then one other, assigning the entire PC’s computing energy to the duty at hand. Intel launched information displaying that when Adobe Lightroom and Premier are used collectively (to edit images whereas a video is being exported) the duties full sooner than when run individually.
Intel
How Thread Director will work from a person perspective continues to be a bit complicated. When you cover an utility, Windows will routinely push it to the marginally slower effectivity or E-cores, Therien stated. But he additionally stated that customers will be capable of configure that conduct themselves. How to try this nonetheless isn’t clear, although Therien implied that it will be ruled by the Windows 11 power mode settings.
And so far as the brand new Apple M1 and M1 Max chips are involved? “We’re very confident in the 12th-gen performance,” Intel’s Mock stated in response.
Intel’s new Z690 chipset for Alder Lake
Normally Intel releases a number of chipsets in help of latest processors, however for now there’s only one: the Intel Z690, manufactured on a 14nm course of.
Intel’s Alder Lake platform helps a number of new key options, lots of which Intel has mentioned beforehand: the introduction of DDR5 reminiscence at speeds as much as DDR5-4800; help for PCI Express 5.0 in addition to PCIe 4.0; plus a wider x8 DMI Gen 4.0 interface, the identify for the interface between each chips and the chipset. (You’ll have the choice of utilizing cheaper DDDR4-3200 reminiscence as nicely, although the general efficiency received’t be fairly as excessive.) That wider DMI interface permits extra bandwidth between the CPU and the chipset, which in flip permits for extra bandwidth to the assorted I/O interfaces. The Z690 additionally natively integrates Wi-Fi 6e, and provides USB 3.2 Gen 2×2 (20Gbps) for higher-speed I/O and peripherals. While Alder Lake helps Thunderbolt 4, nonetheless, it doesn’t seem that the Z690 helps it.
Here’s a block diagram of the brand new Z690 chipset, with a few of its options. Note how there’s a mixture of PCI 5.0, PCI 4.0, and PCI 3.0, and help for 4 unbiased DisplayPort or HDMI shows.
Intel
Intel hasn’t launched a listing of motherboards that might be designed across the Intel Z690, nor has it launched the costs of these motherboards.
One-click overclocking
Intel is offering various instruments to overclock the Alder Lake processors, lots of which is able to most likely be utilized by aggressive fans hoping to attain a couple of clocks increased than rivals when supercooling the chips. All of the Alder Lake “K” chis are totally unlocked, nonetheless, as is the Z690 chipset.
For most customers, there’s one key addition to Intel’s Extreme Tuning Utility (XTU) that might be of curiosity: one-click overclocking with the Intel Speed Optimizer. The Windows-only app will routinely deal with the behind-the-scenes changes of velocity and voltage, in order that the utility will “safely” overclock your system by a small quantity.
Intel
Dan Ragland, the principal engineer overseeing the characteristic, confirmed how the instrument overclocked an unnamed Intel processor from 4.9GHz to 5.0 GHz on the efficiency cores, and from 3.7GHz to 4.0GHz on the environment friendly cores. (It’s probably that Ragland was referring right here to the Core i9-12900Okay/KF, since that’s the one processor supported by XTU rev. 7.5. However, the i9-12900Okay doesn’t help effectivity core clock speeds of both 3.7GHz or 4.0GHz. We requested Intel for additional clarification. Support for extra Alder Lake chips might be added to Intel Speed Optimizer in XTU 7.6, Ragland stated.)
For now, Speed Optimizer’s 100MHz overclock on the P-cores, and the 300MHz overclock on the E-cores, might be a regular characteristic on all Alder Lake processors. Put one other manner, the Intel Speed Optimizer is a “universal” overclock that might be utilized to all Alder Lake chips. Ragland did observe, nonetheless, that utilizing the Speed Optimizer instrument will elevate the voltage out of the accredited specified limits.
Ragland didn’t particularly say that this may void your guarantee, however actually implied it. On the opposite hand, Intel’s Mock famous that the Intel just lately eliminated its optional warranty program on overclocked parts “because we saw so few claims against it,” she stated. “The quality of the parts is quite good, and so we didn’t need it.”
Users may have the choice of tweaking their processors on a case-by-case foundation as nicely, as particular person chips may have their very own particular person tolerances. Performance cores will be individually managed, although effectivity cores can solely be managed in blocks of 4. Intel will help ring (cache) ratios, graphics frequency ratios, in addition to controls over reminiscence ratios, for each DDR4 and DDR5, Ragland stated. Intel can even supply options particular to overclocking in sure situations, equivalent to the flexibility to show off AVX directions in addition to a characteristic to disable hyperthreading.
Intel has additionally added XMP 3.0 help to allow overclocking DDR5 reminiscence, in a similar way to the best way wherein XMP already permits for overclocking DDR4 memory. Intel has additionally elevated the variety of profiles (a mixture of frequency, latency, and voltage) from two choices to 5. (Three profiles might be supplied by the seller, whereas two will be configured by the person.)
What’s somewhat neat, although, is how Intel has mixed the 2 with one thing it calls Dynamic Memory Boost know-how. Previous XMP implementations required the person to toggle between the default reminiscence velocity and the XMP reminiscence state. Dynamic Memory Boost does it routinely and intelligently, scaling the reminiscence velocity up and down relying on the calls for of the system. “Think of this as memory turbo,” Ragland stated. “It’s automatic.”
