According to Intel's chip process roadmap, by 2025, they will master the five generation CPU process in just four years, of which two generations will enter the Amy level process for the first time. In the second half of this year, Intel 4 process will be mass produced, that is, the "4nm" process of standard friends, and it is also the first process of Intel to use EUV lithography machine.
At present, TSMC and < a data link = "1" href = "" target = "_blank" > Samsung have mass produced 4nm process, but Intel's own "4nm" process still has many characteristics, especially in terms of performance. The other two mainly produce low-power chips, while Intel wants to produce high-performance processors, including desktop and server level.
Intel's "4nm" process improves the performance per watt by 20% compared with the current Intel (that is, the second generation 10nm process before it was renamed). If it is compared with the previous first generation 10nm process, the performance is improved by more than 35%
In other aspects, the transistor density of Intel "4nm" process is 100% higher than that of Intel 7 process. The density of HP high-performance library can reach 160 million transistors / mm2, which is higher than 130 million transistors / mm2 of TSMC's 5nm process and close to 208 million transistors / mm2 of TSMC's future 3nm process.
At present, the 12th generation core produced by Intel 7 process and the 13th generation core frequency in the second half of the year can reach 5.5ghz. assuming that the performance is only improved by 20%, the limit frequency should exceed 6GHz, an unprecedented level. I don't know whether Intel will do so**
Intel 4 technology will be launched on the 14th generation of core meteor Lake next year. The latter will also be the first processor in Intel Core series that uses 3D foveros hybrid packaging in large quantities. It is mainly encapsulated in three parts: computing module, GPU module, up to 96-192 computing units, soc-lp, which should include input and output parts such as memory controller and PCIe controller.
