Intel Alder Lake Non-K OC! 12600 @ 5200Mhz

So in a nutshell its 700 quid to overclock a 6 core 12400? Nice little find though, and imagine if Asrock did a B660 for £100 that allowed this base clock tweak. Noice.

It's either great, or a bit pointless, depending on if any B660 boards support it. This result is impressive though, on a 12400:

Another factor is cooling, is this doable on a half decent air cooler?

It does remind be of the value and single core performance of 6 core CPUs like the 9600K, this thing was great in benchmarks and games when overclocked.

I believe derbauer said the 12400 after overclocking was pulling about 100w max, that should be cool able on a half decent cooler.

But right now it's a novelty, it's only confirmed to be working on Asus Z690 Maximus boards using a certain Bios and I doubt many 12400 owners will want to buy a extreme high end motherboard for an entry level CPU

I mean for gaming it still looks like an excellent option to me, besting the 12900K in 2 out of 3 games. If the prices come down on this Z690 board a bit, or you can get one 2nd hand, I'd say it's worth it. It's a good option potentially for people who care less about multithreaded benchmark results.

I'd guess that the 12900KS would still be ahead in these games, but by very little and at very high cost.

It will be up and down. At nearly 5.3ghz all core it's gonna beat the stock 12900k in games that are sensitive to clocks. It's also going to beat the 12900k in games that don't work well with E cores because the 12400 only has P cores and therefore has lower core to core latency. But the one area where it can't beat the 12900k in games that are sensitive to cache or games that want more than 6 cores (I don't expect there are many like this) so overall a 5.2ghz/5.3ghz 12400 should be better than the stock 12900k in most games - and this is precisely why Intel locks down overclocking on these chips, it kills the value of the K CPUs
 
The core to core latency is an interesting thing on the E core models. It's enough to put gamers off these models altogether (the ones that know anyway), if it's really that bad...

What's really odd is disabling the E-cores doesn't seem to help performance in gaming, or gives only small improvements in a few cases:

That's the weird thing about Alder Lake, no 8 P-core only model and no 12400 K variant (maybe not weird from a profit perspective!)... I don't suppose there will be either, as they didn't do this for the i5 11400, 10400 or 9400 line-ups.

He used a stock Intel Laminar CPU cooler apparently, no wonder temps reaching into the 90s... Still, better than I expected from a stock cooler.

I checked the price on the ASUS ROG Maximus Z690 Hero (allowing 'BCLKing') and it's over £500, a ridiculous price :rolleyes:

Will Intel even bother to lock this down, if it's such a niche feature?

It does show the potential of a 6/8 P-Core only chip though (at 5ghz or above), maybe something Intel will need to help them compete with AMD in late 2022.

It does make me think that the usng hybrid design on Raptor Lake could be a really bad idea...

Sadly if you can't use anything other than a £500+ motherboard it makes it utterly pointless. Let's hope there are more/cheaper DDR4 boards that support this feature, and we can all enjoy some actual overclocking and tweaking again, not just buy the most expensive CPU, RAM and board the add 200MHz and be cheering about how totally awesome it is, when it really isn't.

Yes, but these days it's all about pay-to-play. Those who can afford to - or are silly enough to spend money they barely have - are now the Elite of the Elite: better gamers, better overclockers, better people all around. The Super-Men* (* and the vast majority seem to be male).

The rest of us might call them Super-Mugs, but multiple industries have been laughing all the way to the bank with them!
 
@Robert896r1 - Very interesting and detailed work, I'd advise people to look at the summary:

https://kingfaris.co.uk/blog/12900k-core-configs/summary

In effect, enabling hyperthreading and E-cores can reduce the minimum framerate (and average framerate) in games. The most stable configuration overall for framerate was with 8 P-cores enabled, with 8 (not 16) threads enabled.

In addition, you may achieve higher clocks with HT and the E-Cores disabled (5.2ghz in this case)...

It looks like the missing piece in the puzzle was Hyperthreading, really I think there's a strong argument to always turn this off, as HT off improves performance in most cases (except in multithreaded benchmarks).

Even if this feature isn't available on low end boards what it does show is if you buy a cheap Z690 and a 12600k then disable the E cores and OC the CPU to 5.2/3 ghz then you have 12900k performance for half the price.
 
I think a 12700K or KF with the E-Cores and HT off would be better value, when overclocked. You'd only be missing out on the L3 cache.

Can still get decent framerates with the 12400 with less cache, so maybe the L3 cache isn't that important (at least, not without a much larger L3 pool, like with Zen3D CPUs).

Sounds strangely like some other chips…
 
matching 5600x in multithread, wow!

5.3ghz all core on the celeron and 5.4ghz all core on the 12100, breaking world record with ease and cheap coolers
