The Core i5-12600K is the price/performance king in the Intel Alder Lake lineup. With its competitive pricing of $300, it's a clear winner against AMD's Ryzen 5 5600X and faster than even the 5800X in many applications and games. This is the gaming CPU you want.

It's good. But the price of the components like DDR5 and motherboards are beyond what I'm willing to spend for a few FPS more.

Nice little beast, despite not being the most efficient.
Sadly, if Win11 can't get scheduling right, there's probably zero change these will work right on Win10 for a while. I will also have to check the support on Linux.

Nice chip. New motherboard is a bummer. Be nice if there was more new gpus at msrp available. Not much point buying one to pair with an rx480 lol

@W1zzard

any plans to do testing on windows 10???

You don't have to pay for DDR5, most motherboards are built for DDR4. The test system is using DDR5 because it has to be forward-looking, but expect a DDR5 vs DDR4 comparison for Alder Lake in a few days at most.

Intel definitely did expectation management properly this time. Fast? check. Power hungry? check.

Its nice to see real competition again, not just on price, but absolute performance.

Gamers nexus ran 12900k with windows 10 with gear 2 ram lol, still was awesome.

"Beats 5600x conclusively". Well, sure, in pure numbers with no other consideration; 14% overall performance increase in CPU tests with a multi-core increase of 50% power consumption (126w vs 189w). I'm sure each individual test varies, but it's not that impressive in relation to the power increase.

Nice reviews on all the new CPU's regardless!

MT power test is Cinebench, so 126 W vs 189 W = ~+50%, and 11225 CB vs 17699 CB = ~+57%

It's also the motherboard prices.

Sure, It beats the 5600X conclusively by consuming 90W more power. Sorry, the 5600X still gets my money.

Looks like Intel is back on the menu boys :D

Though for 4K gaming, I doubt 12900K make any difference to 9900K

While this will be a good mid-range CPU, I think the 12700k is still the better bang-for-buck value for many use-case-scenario's.

Just now realized that the power consumption test said Cinebench; thanks for replying on that!

I know it's not really feasible (time constraints) to do, but it would be interesting to see power consumption comparisons on other things like gaming and real world application use. I say this because of the huge disparity between something like Cinebench and the Prime95 power charts. It's probably irrelevant anyways as most people don't particularly care about the difference in power consumption as long as the performance is higher.

Linus tech tips youtube leaked slides show ADL consuming less power than zen 3 parts in gaming.

That's whole system power, not just CPU. And that's 63W, unless you stress your system around the clock.

@W1zzard What's up with testing Java8? Java is at version 17 now.

Thanks ! Noted for next rebench (early 2022), wasn't there some compatibility issues introduced with newer versions? or was it a licensing change?

To be fair you could just wait for the non E-core version to come out (12400/12500). Should be still faster than the 5600x but significantly cheaper and less power

From these results, it doesn't look to me like AL has quite caught up to Zen 3 in efficiency. The gap isn't huge, though. Comparing 12600K to 5600X makes notional sense because they share core count (ignoring E-cores) and projected street price, but test results show that the Z3 part that it's most on parity with is the 5800X. With that in mind, and singling out Cinebench as it does a good job loading all cores:

Power consumption

Energy usage
1636033863664.png


Score
1636033952196.png


I'm honestly impressed, and was not expecting AL to perform this well. For my part, the decision of 12600K vs. 5600X is easy, unless I really felt like giving Intel the metaphorical finger. Of course, cost of Z690 boards and the need for more robust cooling tempers that enthusiasm a bit. It'll be really interesting to see where 12400, 12600 and mainstream boards come in for pricing.

Compatibility - not exactly. Some internal APIs which were exposed up until Java9 were properly locked away. Problems have been mostly taken care of in the meantime.
Licensing - yes. But only for whoever installs Java in production environments.

There were however internal changes that may produce very different results from Java 8.

Thanks for the hard work, now go catch some sleep (till Sunday or so).
