The Intel twelfth era codenamed Alder Lake is an important Intel Core structure replace up to now decade. We’re taking a more in-depth have a look at its peak efficiency in CPU-heavy benchmarks and analyzing the implications for energy customers and gaming PC lovers.

We’ve described the structure at size in our Intel Gen12 Alder Lake overview, however right here’s the high-level view: Intel has embraced a heterogenous X86 structure that embeds two totally different CPU core varieties, the “Performance” and “Efficient” cores.

I gained’t go deep into how the brand new {hardware} and software program schedulers work and the way advanced it should have been to construct them. Intel and Microsoft appear to have been doing a fantastic job. We’re going to take a look at peak efficiency, so many threads will look alike, no matter which core kind they run on. We’re aiming for max {hardware} utilization right here.

I count on to see extra nuance from the scheduler after we’ll take a look at Intel’s twelfth gen laptop computer CPUs, the place the heterogeneous nature of those new CPUs ought to shine much more, particularly when it comes to energy effectivity. For peak efficiency, Windows 10 customers shouldn’t fear about potential enhancements in Windows 11’s up to date scheduler.

The new structure lets Intel run extra cores (as much as 16) and extra threads (as much as 24) to raise CPU efficiency to new ranges. Compare that with the 8 cores / 16 threads of the last-gen Core i9-11900K, and it’s simple to see how issues would scale properly for massively multi-threaded apps.


When it involves CPU efficiency saturation, typical benchmarks like GeekBench and Cinebench could possibly be good proxies, despite the fact that they’ll’t mirror all real-world conditions. Even although Intel was vital of Cinebench up to now, that benchmark has a great following within the Creative crowd, and Intel is now doing rather well at it.

Benchmarks usually are not be-all end-all functions, however they supply beneficial perception for particular person elements with the right evaluation. Also, you’ll discover that they approximate many real-world use circumstances fairly effectively.

If something, our have a look at the product “value” (pace/value) on the finish of the overview is likely to be an important “real world” standards, and that’s what I’d use when purchasing for a CPU. More on that later.

Intel Alder Lake CPU benchmarks

We have used the standard Kit that almost all reviewers function for this spherical of checks, and variations sometimes come from kind of aggressive cooling options. The motherboard settings had been left to the “default,” and we’ve not made any makes an attempt to overclock this configuration in the mean time.

Note: we use Amazon affiliate hyperlinks under, and we’ll get a small fee should you assist us by shopping for from these.

Motherboard: ROG STRIX Z690-E Gaming WIFI
CPUs: Intel Core i9-12900K (official specs) and Intel Core i5-12600K (official specs)
DDR5: Micron 2x32GB UDIMM DPARXPM001, PN MTC16C2085S1UC48BA1
CPU cooler: Thermaltake TOUGHAIR 110 140W TDP

Note that Intel’s twelfth era CPUs and Intel Z690 chipset assist each DDR5 and DDR4 reminiscence modules, so you’ll doubtless have to decide on which, based mostly in your funds. At the second, we haven’t run any DDR4 checks, so contemplate these numbers because the best-case situation from a RAM standpoint.

For cooling, we’ve a plain Thermaltake TOUGHAIR 110 CPU heatsink rated for 140W TDP. It ought to mirror what you get in a comparatively commonplace construct, with out liquid cooling or unique (costly) supplies. The general system is very quiet as we use an open case.

Looking at each the Geekbench and Cinebench scores, you’ll notice that each stress the CPUs very effectively, and that’s why they have an inclination to correlate. Basically, Intel is again on the high.

You will discover kind of the identical form of outcomes and rankings on actual apps that may saturate all CPU threads at 100%, like heavy CPU photoshop filters, CPU 3D rendering, and many others. You can run tons of benchmarks and maintain seeing this general image.


Apps that depend on large datasets profit from the superior DDR5 bandwidth, so should you’re an expert, I’d advocate choosing that reminiscence kind. Gamers would possibly save a buck with DDR4 since recreation builders are inclined to optimize RAM utilization to slot in inexpensive computer systems.

I’ll level out that the video games should be CPU-limited for the CPU to affect the framerate closely. That extra doubtless occurs at decrease resolutions like 1080P or barely above. As you scale from 1080p to 1440p, 4K, and 8K, the GPU’s fillrate turns into the first limiting issue because the variety of pixels rises exponentially.

Game builders and 3D Engine builders spend quite a lot of time (actually lots of of man-year yearly) optimizing for multithreading, so it’s a great guess to have a high-thread CPU.

The most superior 3D engines have a pre-rendering move the place all duties are organized in dependency timber and dispatched into quite a few threads that maximize CPU utilization. The likelihood is that Intel’s new CPUs will do very effectively in lots of AAA video games.

CAD and Creative professionals working particular apps would possibly seek for industry-specific benchmarks. But even with out being that choosy, they is likely to be swayed by the worth proposition of those new CPUs. After all, cash discuss.

Value proposition highlights

Intel’s new processors do have wonderful “absolute performance” of their class. You’ll discover far more costly Intel Xeon or AMD ThreadRipper CPUs with barely higher efficiency at a lot greater costs, so “no thanks.”

And that’s why an important metric is “how much CPU speed are you getting for your money?” (efficiency / $)

Looking at our worth information under, the Intel Core i5-12600K ($289) is a stunner, and the Core i9-12900K ($488) is way forward of AMD’s formidable Ryzen 9 5950X ($718) and 5900X ($484), not to mention the 5600X ($299). All these avenue costs are what I discovered at publication time.

And that’s the second side of Intel’s new desktop processors. This new Alder Lake structure brings nice efficiency for the value. That’s what the info clearly reveals. That’s very true for the i5-12600K, which is cheaper than the AMD 5600X however performs noticeably higher.

Whereas AMD merchandise’ worth dominated Intel’s last-generation i9 CPUs, the Alder Lake structure has turned the tables.

Most individuals store for CPUs with a restricted funds, and everybody desires essentially the most efficiency for each greenback spent. If something, the Intel Core i5-12600K ought to be your default selection, and in case your funds permits, the Core i9-12900K is superior.


Talking about “value,” you must examine the full value of your system, together with DDR5 and the motherboard. Both is likely to be costly this shut proper now, however issues would possibly ease off quickly.

Gamers can safely bounce onto this new Intel platform with future-proof options resembling PCIe 5.0 that ought to assist with future graphics playing cards, DDR5 for absolutely the quickest reminiscence, and the brand new Intel Z690 chipset that has higher IO and bandwidth.

Power consumption is often not an enormous issue for high-performance desktop computer systems, however I’d level out that the Core i9-12900K attracts extra energy than its AMD rivals at peak workloads. If you had been to construct a server farm, this could possibly be an extra criterion, however I don’t assume it’s a giant issue for people.


Intel did it! I didn’t know if this new structure would ship at this degree. It was important to see it in motion, and the outcomes converse for themselves: Intel has regained its (gaming) CPU crown.


For IT-related utilization or sustained heavy workstation-type workloads, you would possibly wish to put money into a elaborate cooling answer to verify thermals don’t restrict the efficiency. I used to be impressed by the pace, even with a plain heatsink.

And I think there’s extra to find from Intel’s Alder Lake CPU structure. These desktop processors present the form of absolute peak efficiency we are able to get. However, the laptop computer variations will, no doubt, provide new ranges of efficiency and battery life (power-efficiency). I’m very a lot wanting ahead to it.
