Intel Core 12900K Review and Features

Beginning with the first in class Core i9-12900K CPU, we can at last show you how Intel’s new twelfth age Alder Lake processor design performs. The chip is evaluated at $650, and that implies Intel has situated their new leader work area CPU solidly between the Ryzen 9 5900X and 5950X, which will right now impaired you $520 and $750, individually.

Today is about certifiable execution as we took care of currently the 12900K’s particulars, for all that decency look at our Alder Lake review here.

The Core i9-12900K is a fascinating monster, pressing 8 execution centers alongside 8 productive centers for a sum of 24 strings, which appears to be a peculiar number and that is on the grounds that those proficient or “E-centers” don’t uphold Hyper-Threading.

The P-Cores clock up to 5.2 GHz with the E-Cores restricted to 3.9 GHz. There’s 30 MB of L3 store, a sum of 14MB of L2 reserve, 16 PCIe 5.0 paths from the CPU and four PCIe 4.0 paths. Another new component is DDR5 memory support, however Alder Lake additionally upholds DDR4. You’ll need to pick which memory innovation you need to coordinate your twelfth gen processor with however since you can’t blend the two.

The stock memory support incorporates either DDR4-3200, or DDR5-4800 and today we’ll test both, however we won’t waste time with DDR5-4800 and on second thought to amplify what this new memory innovation truly offers, we have prepared our Alder Lake CPU with G.Skill’s Trident Z5 DDR5-6000 CL36 memory.

With respect to the motherboards, we’re involving the MSI Z690 Unify for DDR5 testing and the MSI Z690 Tomahawk WiFi DDR4 for our DDR4 test framework. Both motherboards function admirably and we value the way that MSI has nailed their BIOS out of the door. All application and gaming information was gathered utilizing the Radeon RX 6900 XT illustrations card.

Because of the half breed center plan of Alder Lake, the 12900K alongside the majority of the twelfth gen processors require Windows 11 and its better string scheduler for ideal execution. Thusly we’ve tried utilizing a new introduce of Windows 11 and have refreshed any remaining benchmark information for Ryzen and different CPUs running Microsoft’s most recent OS.

The Ryzen test framework is running the Asus ROG Crosshair VIII Dark Hero motherboard with the most recent BIOS update, and obviously, every one of the most recent Windows updates and drivers. It’s been a mammoth errand finishing this information in time for the Alder Lake send off, and indeed, there is something else to come as we’re dealing with surveys for the Core i7-12700KF, trailed by the Core i5-12600K survey, and substantially more.

We’ll begin with Cinebench, and without skipping a beat we can perceive you these outcomes are exceptionally great. The 12900K figures out how to make the Ryzen 9 5950X look slow, helping multi-center execution by 13%.

We’re likewise taking a gander at a 76% exhibition improvement from the 11900K (!) and that thing was delivered only 9 months prior for $550, just $100 not exactly the 12900K.

We did firmly prescribe to keep away from the 11900K at all costs, and seeing these outcomes simply affirms our underlying position.

As extraordinary as application execution looks, it comes at the expense of gigantic power use. Though the 5950X saw complete framework utilization arrive at 221 watts with a piece quicker execution, the 12900K crested at more than 350 watts. That is a 60% increment in complete framework power use which is a cosmic contrast.

At last, for those considering how the 5950X consumed less power than the 5900X, this is definitely not another thing, it is normal and it’s because of the greater silicon nature of the 16-center part.

For those pondering clock speeds, here’s a gander at the 12900K under all-center burden in Cinebench R23. As you can see the P-centers timed to generally 4.9 GHz at 4888 MHz with the E-centers at 3.7 GHz, so both are near the greatest clock recurrence as we’re not running with any implemented power limits which is currently the default conduct.

Then for single center burden the 12900K is timing to 5.1 GHz for the P-centers and 3.9 GHz for the E-centers in this responsibility.

Concerning working temperatures, the 12900K is a power hungry CPU for these sorts of all-center responsibilities and as such I couldn’t stay away from discontinuous choking with the Corsair iCUE H115i Elite Capellix introduced as the CPU consistently ran at or extremely close 100C. These coolers in all actuality do have mounting pressure issues with the 12900K, yet I gave my all to address that while additionally including more than adequate warm glue, in any case this sort of arrangement isn’t great for delayed all center burden.

Exchanging over to the MSI CoreLiquid S360 did help and the mounting pressure was more predictable across the IHS. This cooler tried not to choke of any sort, yet the center temperature actually crested at 96C, however temperatures generally drifted in the mid to low 80s.

Despite the fact that we’ve just possessed energy for restricted testing it seems like 240mm AIO fluid coolers are not feasible as 12900K proprietors will require bigger 360mm adaptations. That implies for a good cooler you’ll be paying more than $100 with the greater part of the Corsair and MSI models evaluated at or above $200. In the interim, the Ryzen 9 5950X can be kept cool with a half good air-cooler.
