Intel Core i9-12900K 36% Faster Than Stock in Maximum Turbo Power Mode

The recently announced Intel Core i9-12900K is set to launch on November 4th alongside the i7-12700K, and i5-12600K which is the date when we will see reviews for the processors released. We have already seen numerous leaks regarding the processors performance leading up to the announcement and we have now received some new leaked performance figures for the processors when operating in Maximum Turbo Power (MTP). The MTP is defined by Intel as the maximum sustained power dissipation of a processor compared to TDP which is the base power draw. The performance difference between these two power modes has been revealed from Cinebench R20 multi-threaded results posted by Wofstame the Gaming Desktop Product Planning Manager for Lenovo China.

The Intel Core i9-12900K scores 7492 points when running at its TDP of 125 W and 10180 points or 36% faster when operating at the MTP of 241 W. This performance difference is less notable for the other processors with the Core i7-12700K seeing a 30% improvement between its 125 W and 190 W power modes while the Core i5-12600K sees a 10% improvement from the 125 W TDP to 150 W MTP. Intel appears to be extracting the maximum performance from their Core i9-12900K with diminishing returns from the increased power budget compared to the other processors.

Intel "Alder Lake-S" Comes in a 6+0 Core Die Variant

Intel's 12th Gen Core "Alder Lake-S" silicon apparently comes in two variants based on core count. The first one is a larger variant with 8 P cores and 8 E cores, while the second variant is a visibly smaller die with only 6 P cores, no E cores. This was revealed by an MSI Insider video presentation where pictures of LGA1700 packages with the two die types were shown off.

MSI also confirmed die-sizes and dimensions of the two. The larger C0 die measures 10.5 mm x 20.5 mm, working out to 215.25 mm² area. The smaller H0 die measures 10.5 mm x 15.5 mm, and a die area of 162.75 mm². The H0 silicon completely lacks "Gracemont" E-core clusters, and physically features six "Golden Cove" P cores. It's possible that given the 3 MB L3 slice size on the larger C0 silicon, the smaller H0 silicon physically features 18 MB of shared L3 cache.

Final Intel 12th Gen Core CPU Spec and Pricing Leak Hours Before Official Reveal

For those tired of Intel leaks, please look away now, as this is likely to be one of the last leaks before the official reveal later today. The final specifications, as well as pricing for the first six of Intel's 12th Gen Core CPUs has made an appearance online and the good news is that the official pricing isn't as bad as we've been led to believe, based on earlier leaks and it'll at least make up some of the cost increase of the Z690 motherboards over the Z590 models.

Spec wise, we're not looking at anything unexpected here, it simply verifies what has leaked so far, with one exception, maximum turbo power. Although the base TDP of all six CPUs is 125 W, it seems like Intel is using the maximum turbo power as yet another product differentiator, at least more so than it has previously. The Core i9 CPUs get a maximum turbo power of 241 W, whereas the Core i7's top out at 190 W and the Core i5's at 150 W. At least Intel is being open about it and the question is if it will have any affect on overclocking or not. Obviously having fewer CPUs cores would result in a lower power draw overall, but then the question is why the Core i5's have a base TDP of 125 W.

Intel Core i5-12600K CPU-Z Scores Show 50% Higher Multi-Threaded Results Than i5-11600K

Intel's upcoming Alder Lake-S lineup of processors is shaping up to be a rather good generational improvement. With wonders of the Intel 7 process, previously called 10 nm Enhanced SuperFin (10ESF), the processor lineup will deliver new hybrid technology, mixing new big and small cores into one package. Today, some new CPU-Z validation tests have shown up for the Intel Core i5-12600K CPU, which directly replaces the previous Core i5-11600K Rocket Lake model. With six high-performance Golden Cove and four efficient Gracemont cores, the Core i5-12600K CPU is a ten-core design with 16 threads. And compared to the 6C/12T i5-12600K CPU, the performance is much higher.

According to CPU-Z scores, the new Alder Lake processor scored 7220 and 7156 points for a multi-threaded benchmark in two tests. Compare this to the previous-generation model, which scores 4731 points, and the new chip is almost 50% faster. According to CPU-Z, the new CPU achieved this while running at a boost frequency of 4.5 GHz to 4.7 GHz.

Intel Core i5-12600K 47% Faster Than Ryzen 5 5600X in Leaked CPU-Z Benchmark

The Intel Core i5-12600K is set to feature 6 high-performance cores and 4 high-efficiency cores running at base speeds of 3.7 GHz and 2.8 GHz respectively. These cores can boost to 4.9 GHz and 3.6 GHz with Turbo Max Boost 3.0 however we don't expect much more speed can be extracted out of them using overclocking so default performance with sufficient cooling should be close to max. We have recently seen some CPU-Z test scores for the processor from prominent leakers which show the chip scoring 746 and 7058 points in the single-threaded and multi-threaded tests when running stock on Windows 11. The processor was also tested with an unknown overclock on Windows 10 where it scored 79X and 72XX points respectively.

These scores are extremely competitive with them easily beating the Ryzen 5 5600X by 19.5% and 46.7% in single-threaded and multi-threaded tests. We still don't know where Intel will position the Core i5-12600K in the market so any judgment on the value of these processors will need to wait until release. While we don't currently know the expected MSRP for the Core i5-12600K we have seen pricing for the Core i7-12700K and Core i9-12900K at 469.99 USD and 669.99 USD respectively. Intel is expected to announce these Alder Lake desktop processors during an event on October 27th with general availability expected November 4th.
