Hardware

In an early test, the Core i9-13900K outperformed the Core i9-12900K by 10% in games and 42% in apps.

Chinese sources published one of the first reviews The Core i9-13900K is the flagship processor of the Raptor Lake family, due for release at the end of September. Tests have shown that the Core i9-13900K performs noticeably better than the current flagship Core i9-12900K processor from the Alder Lake family in all types of applications, including games.

A joint review of the Core i9-13900K was published by Chinese enthusiasts hiding under nicknames Enthusiastic Citizen and OneRaichuwhich often publish the results of experiments with processors before their official announcement.

From the review it became known that the Core i9-13900K has 8 productive and 16 energy-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 in Alder Lake processors. Performance cores in Raptor Lake have 2MB L2 cache per core (vs. 1.25MB for Alder Lake), and power-efficient cores have 4MB L2 cache per four cores (vs. 2MB per four cores for Alder Lake). In addition, the Core i9-13900K has an increased L3 cache of 36 MB (the L3 cache of the Core i9-12900K has a volume of 30 MB).

Significantly higher in Core i9-13900K and operating frequencies. Its productive cores operate at a frequency of 5.5-5.8 GHz (depending on the load), and energy-efficient cores operate at a frequency of 4.3 GHz. Also in tests it turned out that the ring bus Raptor Lake works at a higher frequency and has better efficiency.

Comparing the Core i9-13900K and Core i9-12900K in computing tasks showed that the new processor delivers 42% faster performance. This value is the sum of the frequency advantage and the IPC increase (specific power per clock). The performance gain at the same frequency was estimated by Chinese enthusiasts at 13% for productive cores and 6% for energy-efficient cores.

In gaming tests, a Core i9-13900K-based system performed an average of 10% better than a similar Core i9-12900K-based configuration.

At the same time, the Core i9-13900K “exceeds” its predecessor in terms of power consumption. In the AIDA64 FPU stress test, the new processor consumed 343 W, while the Core i9-12900K was satisfied with one and a half times less power.

The Core i9-13900K was tested with DDR5-6000 and DDR4-3600 SDRAM and a Radeon RX 6900 XTXH graphics card. The NZXT Kraken X73 CBO was used for cooling, and the consumption limit of 253 W set by the specification for the Core i9-13900K was lifted in tests.

The official announcement of the Raptor Lake family of processors, led by the Core i9-13900K, is scheduled for September 27th.
