GamerMeld video, apparently it requires a fairly high-end Asus mobo. Waiting for the ASRock B660 board that can do this, or a Z690 Pro4 board.
It isn't quite that straight-cut.If I could get a rough equivalent bump as spending another $50 to get the next step up the CPU ladder, I'd certainly be happy to pay another $20 for a board that would let me do that. It probably doesn't take $20 worth of parts to enable that kind of functionality either.
So Purchase a Locked Non-K CPU, get yourself an Expensive MB and DDR5 RAM and you can match a 12700K in Single Thread?.... Meanwhile some people are running top of the line 5000 Ryzen on $50 MB without issues
it requires an external bclk clock gen, so no low end boards will have it probably
It isn't quite that straight-cut.
Only in the case of lightly threaded applications does this really gain you a lot, and in that case, the next CPU up might give you half of those gains anyways ($31 more for the 12600 gives you half the frequency increase you get from overclocking the 12400). Free performance is always great, but it is not necessarily as good as you put it.
- With the current CPU lineup, the next model up is often not $50 more expensive. Suppose you stay within the brand level (same number of cores). Then, the 12100 to 12300 is $21. The 12400 to 12600 is $31. The savings isn't $50.
- Or if you go up a brand level, a 20% overclock (which is roughly what Der8auer got) might not overcome the gain of more cores. i3->i5 is 25% more cores. i5->i7 is 33% more cores even if you don't count the efficiency cores. So for multithreading applications, the next model up may actually be faster than the overclocked chip.
How long before Intel tries to kill this with a microcode update?
Shhhhh!
In all seriousness, back in the day I did downgrade the BIOS on my Z170 mobo just to retain the non K overclock... well that was until I realised AVX was broken if you did. Ended up just getting a 6700K after that haha
FYI for 12400 @ 5.3Ghz you're going to need an AIO to keep the cores cool (which is exactly what der8auer was using). Average chip power consumption won't be the problem for air cooling (especially in gaming), but hot spots will be. The board quality will also likely limit maximum OC capabilities, since value boards won't offer the same quality for power delivery, which means slightly higher Vcore for stability, which means more heat.Anyway, let's hope this function filters down to some lower end (or at least midrange) mobos, the gaming performance of an i5 12400 @ 5.3GHz is actually at 12900K level.

Somewhere around 4.6-4.8Ghz will be a more feasible target for 'value' air coolers, which is still a respectable 15-20% increase in gaming clocks.
We'll see results in practice, all I can point out at the moment is that Roman's overclocked 12400 hit 96C in CB23 while running under water. It's not clear from the video that his setup was an AIO, but he did mention he was using an AIO on the Celeron OC video (when he switched to a custom loop).How bad is the hot spot situation with ADL? I'm aware its a smaller die and all, but didnt Intel dispense with the TIM and are using solder to mitigate the heat transfer problem?

I'll keep an open mind though, let's see what can be achieved with a value board and a budget cooler.
So, I looked this up. The motherboard and CPU is $450. The cheapest memory I could find that is decent speed is 5600 and its $400 !! So $850 for 6 cores.Looks really promising. i5-12400(F) @ 5.0Ghz all-core, on a more reasonable B660-F ROG STRIX WIFI ATX board. Only minor flaw is, you'll have to source some DDR5 RAM for the board.
I would have liked for him to address whether or not the onboard video is disabled during a BCLK OC ala Skylake, or if it still functions, along with SATA, because Intel de-coupled BCLK on 12th-Gen.
Good news. But we have to wait months until these mobos available...
If it takes months, I expect Intel will shut it down before that hits the market though.
