Intel Alder Lake Overclocking Showcases with All-P-Core 5.2GHz overclock

Intel's Alder Lake series processors are launching soon, but it looks like retail processors are already in the wild amongst overclockers. Thanks to @9550pro, we have a look at some benchmark results from an i9-12900K that has had all of its performance cores (p-cores) overclocked to 5.2 GHz, delivering incredible levels of single-threaded performance. 

In CPU-Z's single-threaded benchmark, Intel's 5.2GHz i9-12900K achieved a score of 851 points, smashing the benchmark's reference Ryzen 9 5950X score of 648. That said, the multi-threaded performance of Intel's overclocked i9-12900K was similar to AMD's Ryzen 9 CPU. 

The benchmarks below used an Alder Lake i9-12900K processor with 5.2GHz Performance Cores and 3.7 GHz Efficient Cores, with the CPU reportedly consuming 330 watts of power. Some reports have claimed that these power consumption numbers a similar to Intel's i9-11900K, revealing significant power efficiency gains from Intel. 

The Problem with CPU-Z Benchmarking

While CPU-Z's benchmark is a valid test, it must be noted that CPU-Z performance is not indicative of real-world performance. These scores do not necessarily mean that Alder Lake will deliver faster rendering times than Ryzen or better gaming performance. To make proper judgements on Alder Lake's performance, we need data from a variety of benchmarks and applications. 

Alder Lake's single-threaded performance may appear to be strong in CPU-Z, but that does not mean that it will be strong across all applications. We need to see broader testing for Alder Lake to come to those conclusions. 

So far, Alder Lake appears to be a solid improvement over Intel's existing 10th and 11th Generation Core CPU architecture. So far, rumours regarding Alder Lake's single-threaded performance have been positive, though we will have to wait for proper reviews for Alder Lake before we can come to any firm conclusions. 

5.2 GHz All-P-Core overclocks for Alder Lake point towards strong overclocking potential for Intel's 12th-generation platform, which is great news for hardware enthusiasts. That said, it remains to be seen how easily Alder Lake can be kept cool under such high loads.

330 Watts for just the cpu... we gonna be needing 800 or 1000 watts power supplies again paired with anything higher then a 3070.

Crazy world where for the longest time everyone was trying to limit the power draw and make things efficient, and here we are right back to the start again.Quote

It's a crazy amount of power for a CPU imho thats as much as my 6800XT uses under full load when overclocked, personally i prefer 65watt chips that when oc'd maybe eat double.

I do feel however that the reason they wanted to save power wasn't to use less but gain more performance for the same power.

I got a 850PSU not as my system needed it but so it's never at full load a chip like this would make that much harder.

Oh and Intel I haven't forgotten your glue comments must be a very sticky cpu Quote
