In case you missed it earlier, Intel's 10nm Alder Lake CPUs will be based on a hybrid CPU design, featuring up to eight Golden Cove performance CPU cores and up to eight Gracemont efficiency cores (P-cores and E-cores).
A leak coming from Chinese sources, and picked up by Videocardz.com, has revealed some of the first alleged specifications of the first three SKUs, including the Core i9-12900K, Core i7-12700K, and the Core i5-12600K.
The flagship Core i9-12900K will have an 8+8-core configuration, 30MB of L3 cache, and 125W/228W TDP (PL1/PL2). The P-cores will boost up to 5.0GHz (1-2C) while E-cores will boost up to 3.7GHz (1-4C).
The Core i7-12700K, should be based on an 8+4-core configuration, pack 25MB of L3 cache, and have the same 125W/228W TDP. The P-cores on the Core i7-12700K boost up to 4.7GHz (1-2C) while those four E-cores boost up to 3.6GHz.
The 12th gen Core i5-12600K is based on a 6+4-core configuration, packs 20MB of L3 cache, and, surprisingly, has the same 125W/228W TDP. Those four performance cores boost up to 4.9GHz, while E-cores will boost up ot 3.4GHz.
Intel's Alder Lake desktop CPUs are expected to launch by the end of this year or in early 2022 and will bring a new LGA1700 socket, 600-series chipset motherboards, and more. Intel has already promised up to a 20 percent increase in single-thread performance, up to 2x multi-thread performance, improved SoC power, DDR5 and PCIe Gen5 support, and more.
