German portal TweakPC published the test results of the flagship 16-core Core i9-12900K, Core i7-12700K 12-core, and Core i5-12600K 10-core processor in the Cinebench R20 and Cinebench R23 synthetic benchmarks.

The Alder Lake series flagship model was tested with four different power limit settings (125/150/180/241 W) to show how increased power consumption improves chip performance. How previously reportedIntel decided to ditch the old TDP or PL1 in Processor Base Power (PBP) and PL2 in Maximum Turbo Power (MTP).
Observations have shown that the Core i9-12900K can add up to 28% in performance with an increase in power limit from 125W (PBT) to 241W (MTP). The test was carried out using a liquid cooling system that prevented the processor from heating up above 81 degrees Celsius.

For comparison, the Core i9-12900K was also tested with the Dark Rock Pro 4 air cooler, leading to a very different picture. With the maximum power consumption set, the chip temperature reached 100 degrees Celsius in just 4 minutes from the start of the test:

Below are screenshots of the performance test results for the Alder Lake processors in the Cinebench R20 and Cinebench R23 benchmarks with maximum power consumption. The source only provided multi-core benchmark results. For comparison, the 16-core AMD Ryzen 9 5950X flagship in the multi-threaded Cinebench R23 test is gaining around 28,641 points, meaning Intel’s new flagship with fewer threads is as close as possible. of the competitor.

The official launch of the Alder Lake-S processors will take place today. More details on the flagship model will be available in our full review. The MSRP of the flagship Core i9-12900K model is $ 589, the Intel Core i7-12700K model is priced at $ 409, and the younger Core i5-12600K model has an MSRP of $ 289.
