A consumption peak at 378 W in Prime95.
Intel has still not formalized Raptor Lake processors, but engineering sample tests have been going on for several weeks. the Core i9-13900K, already reviewed by Extreme Player last July, reappears, this time under the spotlight of Erjin Homemade Taobao. However, the chip is not in its best light.
The marking of the processor is concealed, so we cannot determine the revision. With the launch of the 13th generation Cores being close (mid-October), it is likely that the chip is quite recent. Anyway, this copy of Core i9-13900K was compared to Core i9-12900K on various benchmarks and games. Both processors take place on an MSI Z690 Godlike motherboard. Cooled by a 360 mm AIO kit, they collaborate with DDR5-4800 RAM and a GeForce RTX 3090 graphics card. Note that the Core Raptor Lake has 8 P-cores and 16 E-cores, i.e. 24 cores / 32 threads; Core Alder Lake has 8 P-cores and 8 E-cores, or 16 cores / 24 threads.
Results
Under AIDA64, with frequencies set at 4.9 GHz and 5.2 GHz, the Core i3-13900K consumes less and therefore heats up less than its ancestor.
However, in Prime95, with all 5.2 GHz P-cores, the chip no longer conceals its gargantuan appetite for watts : it swallows 378 W.
This is followed by some Cinebench and CPU-Z tests. Unsurprisingly, the Raptor Lake, which has more cores, takes the lead in multi-threaded tests. The balance of power is sometimes reversed in single-core.
Same observation in games at 1080p, with mixed performance for the Core i9-13900K. Assume a driver problem.
Intel is expected to introduce Raptor Lake processors on September 27. These would be available from October 20. Yesterday, a leak revealed a Raptor Lake range comprising 14 references. However, it is likely that initially the company offers only the best representatives of each series, namely the Core i9-13900K / Core i7-13700K / Core i5-13600K.
