Intel Core i5 12600K and Core i9 12900K With ASUS ROG Maximus Z690 Hero Review

Test Setup and Overclocking

Intel Core i5-12600K and Core i9-12900K Review

Test Setup

With an entirely new platform we've taken the opportunity to update our test system to include Windows 11. We've also got some DDR5 from Corsair in the form of the Dominator Platinum. Plenty of scope to make the new 12th Generation Intel CPUs perform to their best.

Overclocking

The Core i9-12900K is very flexible when it comes to overclocking options. The Intel Extreme Tuning utility delivers what they promised by improving the fine control you have over every aspect. It is worth mentioning that, like most recent processors, the automatic boosting is so well honed that manually extracting extra performance without delving into the world of extreme cooling doesn't give the same massive improvements we used to see. There is still more to be found though, as you'll see in our results. With the early BIOS on the Hero we used we found their AI overclocking option to be less refined than we would expect. Scores dropped by a minimum of 25%, going the manual route in the bios just gave use blue screens and grey hairs so for the first time in history we reverted to using Intel XTU, it was annoyingly good and genuinely rescued us from flipping tables and throwing equipment around the room.
Asus - please sort the BIOS quickly.

(EDIT on the day of launch) still no BIOS update to address this yet.

It's also worth noting that DDR5 has the curious capability of being Dual-Channel on a single stick, and Quad-Channel with just two sticks - as we have here. The benefits of limiting DDR5 to dual-sided DIMMs only. Impressive stuff going on under the hood of the newest Intel architecture.

Have to say i'm a bit non plussed with the overall platform cost / efficiency compared to my current X570 & Ryzen R9 5950X.
Have a few questions Tom if I may,
- ref Win 11 & W10? Have you or will you be trying the new platform on Win 10?
- Looking at the power draw figures, am I right in thinking that Intel is still about 20% off AMD on 7nm taking thread count, platform (what is DDR5 in power, X690 in power) cost?
- What are boot times for 12th Gen and X690?

Thanks for the review.Quote

I dont feel so bad now. Gaming wise i see little boost for me, but the temps are a definate pleaser.

Makes me wish I held out longer and got this Glacial instead of the Z590 when I see how good it looks, but Alder lake looks to be a success for sure.Quote

Yeah gaming wise there won't be much in it at 1440P, I'm guessing the "Average FPS" section is at 1080P as it does not say, I never play at 1080P anymore so gaming wise 12th gen would not be an upgrade for me, Gonna wait for AMD's stacked cache 5800X see how that goes.Quote
