Intel 12th Gen Core i9-12900K Processor The Intel 12th Gen Core i9-12900K Alder Lake Processor comes with 3.70 GHz up to 5.20 GHz clock speed, 16 cores, and 24 threads. This new 12th gen Alder Lake Processor is manufactured with 10nm Lithography. The packaging on the Intel Core i9-12900K box is very fancy and chip. And also comes packed within two circular containers which resemble a CPU wafer and opening these up will reveal the chip itself inside its plastic clamshell case. Intel's Core i9-12900K processor is arranged in 8 P-Core (with 16 threads) and 8 E-Core (with 8 threads). Its 30 MB of L3 cache, arranged in 3 MB per core partitions on the P-Core (Golden Cove) and 3 MB per cluster on the E-Core (Gracemont)   Advanced Facilities from Corei9-12900K This processor features a P-Core base and boost clocks of 3.2 GHz / 5.3 GHz and an E-Core base and boost clocks of 3.0 / 3.9 GHz. The boost clocks of this processor are for a single-core. The all-core boost frequencies are expected to be 5.0 GHz for the P-Core and 3.7 GHz for the E-Core. That's 8 P-Cores for 24 MB from the P-Cores and 6 MB from the two clusters comprising 4 E-Cores each. There's also 1.25 MB of L2 cache for a total of 12.5 MB on the entire chip. Intel's Alder Lake will feature both DDR5 and DDR4 memory controllers and 600-series motherboards will also come with DDR5/DDR4 specific options. High-end motherboards will retain DDR5 while the more mainstream offerings will open up DDR4 support also. The latest Intel 12th Gen Core i9-12900K Alder Lake Processor comes with 03 years warranty.
