Alder Lake integrated with different design CPU core
The new CPU to be tested this time is "Core i9-12900K" with 16 cores 24 thread CPUs, the top model, and "Core i5-12600K", a 10-core 16 thread CPU.All of them are ALDER LAKE -based CPUs manufactured in the "Intel 7" process, which developed the 10nm process, and uses the newly designed LGA1700 for the CPU socket.
ALDER LAKE has a high -performance CPU core called "PRFORMANCE Core" and a high -blid architecture that integrates CPU core with different designs called "E -core", a high -efficiency CPU core with excellent power efficiency.Introduced.Alder Lake's P core adopts the "Golden Cove" architecture compatible with Hyper-Threading, and the E-core uses the "Gracemont" architecture, which has developed a power-saving CPU core.
Functions other than the CPU core have been renewed, and the PCI Express of the DGPU integrated into the CPU GEN 5 (PCIE 5).In addition to 0), it also supports new DDR5 memory.The Alder Lake memory controller also supports the conventional DDR4 memory, and can use either DDR5 and DDR4 according to the specifications of the memory slot equipped with the motherboard.
Alder Lake has changed its power indicators on the specifications, and instead of "TDP", which has been used as an index of fever and power design, "Processor Base Power (PBP)" and "Maximum Turbo Power (MTP)".A new power index was introduced.PBP is the same as the conventional TDP, which is synonymous with the maximum power consumption during base clock, and MTP is a maximum power consumption that restricts Turbo Boost operation.MTP is a clue to know the maximum power consumption of the CPU, but it is important to note that the actual power limit value depends on the specific set value of the motherboard.
