In an early review, the Core i9-13900K outperformed the Core i9-12900K by 10% in games and by 42% in applications

Chinese sources have published one of the first reviews of the Core i9-13900K, the flagship CPU of the Raptor Lake family due out in late September.
Tests have shown that the Core i9-13900K offers noticeably better performance than the current flagship Core i9-12900K processor of the Alder Lake family, in all types of applications, including games.
Chinese enthusiasts hiding under the nicknames Enthusiast Citizen and OneRaichu, who often publish results of experiments with processors before their official announcements, have published joint review of Core i9-13900K.The review shows that Core i9-13900K has 8 efficient and 16 power efficient cores in its arsenal, which gives it the ability to run 32 threads simultaneously.
These cores are slightly different from Golden Cove and Gracemont cores in Alder Lake processors.
The performance cores in Raptor Lake have 2 Mbytes of L2 cache per core (vs.
1.25 Mbytes for Alder Lake) and the energy efficiency cores have 4 Mbytes of L2 cache per four cores (vs.
2 Mbytes per four cores for Alder Lake).
Also Core i9-13900K has increased L3 cache to 36 MB (Core i9-12900K L3 cache has 30 MB).Core i9-13900K has significantly higher operating frequency.
Its performance cores run at 5.5-5.8GHz (depending on load) and power efficient cores run at 4.3GHz.
A comparison of Core i9-13900K and Core i9-12900K on computational tasks showed that the new processor gives 42% higher performance.
This value is the result of both frequency advantage and IPC (specific performance per clock) growth.
Chinese enthusiasts estimate the performance gain at the same frequency 13% for efficient cores and 6% for energy efficient ones.In Gaming tests performance of Core i9-13900K-based system is 10% higher than analogous Core i9-12900K-based configuration on average.At that Core i9-13900K \"surpassed\" its predecessor in terms of power consumption.
In AIDA64 FPU stress-test the new processor consumed 343W, while Core i9-12900K took 1.5 times less power.The tests of Core i9-13900K were done with DDR5-6000 and DDR4-3600 SDRAM and Radeon RX 6900 XTXH graphic card.
NZXT Kraken X73 was used for cooling, 253 watt test power limit of Core i9-13900K was removed in tests.The official release of Raptor Lake processor family headed by Core i9-13900K is planned for September 27th.
