    Description

    12th Gen Intel Core i9 12900HX | Review

    Launched in January of 2022, 12th Gen Intel Core i9 12900HX is a High-end processor for laptops powered by 6 performance cores with 12 threads and 8 efficiency cores with 8 threads. The performance cores have a base clock of 2.3 GHz and a boost clock of 5 GHz the efficiency cores, on the other hand, have a base clock of 1.7GHz and a boost clock of 3.6GHz. The i9 12900HK is based on Intel’s 10 nm architecture with this the 12th Gen CPUs see an average IPC gain of 19 percent the higher IPC allows the Alder lake CPUs more performance at the same clock speed. The TDP of this Chip as specified by intel is 55 watts and can go up to 157 Watts (PL2) that being said most laptops will be utilizing 60 watts (PL1) for the performance boost. It also has support for new faster DDR5 memory of up to  4800MHz and low power LPDDR5 5200MHz while also supporting DDR4 memory of up to 3200MHz and low power LPDDR4X 4267MHz. Other Key Features Include Intel UHD Graphics 770 (Alder Lake), and support for USB 4 (40Gbps).
