On June thirteenth, based on AnandTech, Intel has now shared some information about its next-generation Intel 4 course of.
In response to studies, the method will likely be used for merchandise launched in 2023, and it’s Intel’s first course of to make use of EUV.
Intel 4 will likely be used first for Intel’s upcoming Meteor Lake processors, which will likely be a part of Intel’s 14th Gen Core household. Along with vital developments in course of know-how, Meteor Lake will likely be Intel’s first tile/chiplet-based consumer CPU, utilizing tile modules similar to I/O cores, CPU cores, and GPU cores.
In response to information launched by Intel, the Intel 4’s fin pitch has dropped to 30 nanometers, which is 0.88 occasions the scale of the Intel 7’s 34 nanometer pitch. Likewise, the spacing between the contact gates is now 50nm, down from 60nm beforehand.Intel claims Intel 4 is twice as dense as Intel 7or extra particularly, the scale of the transistors has been halved.
Moreover, the brand new course of makes vital modifications to the steel layers. Intel changed copper with cobalt on the backside layer of its Intel 7 course of, which the corporate believes is important for transistor longevity causes. Nonetheless, cobalt is not that nice from a efficiency standpoint, and has lengthy been suspected to be one of many predominant obstacles for Intel’s Intel 7.
For Intel 4, Intel continues to be utilizing cobalt, however now as an alternative of pure cobalt they’re utilizing what is known as enhanced copper (eCu), or copper clad cobalt.
When it comes to efficiency, it’s reported that the frequency of Intel 4 is 21.5% increased than that of Intel 7 below the identical energy of 0.65v. At 0.85v and above, the isopower achieve is near 10%.
In response to Intel,Intel 4 has greater features in energy effectivity. On the similar frequency (round 2.1 GHz), the Intel 4 consumes 40% much less energy. Diminishing returns as frequency will increase.
