The Intel 4 could potentially offer 20% higher clock speeds at a similar power consumption compared to the Intel 7 according to a new leak. This could mean that CPUs can breach the 6GHz mark if it applies to higher frequencies.
Intel 4
-1.8-2.0x HP scaling
-40-50% less power, +12% peak perf (@davidbepo)
-4:3 fin depopulation
-2nd gen contact over gate
-2nd gen single dummy gate
-eCu = Ta/Co barrier + pure Cu
-2x MIM cap scaling (10x vs 14nm)
-18 layers (+1)
-EUV: -20% masks, -5% total steps (vs. 7) pic.twitter.com/325HwQEKug

Leaked slides from Intel’s forthcoming presentation at the IEEE VLSI Symposium 2022 shared details of the Intel 4 process node and a die shot of the Meteor Lake-P processor which remains unreleased as of now. The 14th-gen Meteor Lake CPUs are expected to be released in 2023, following the Raptor Lake release this year.
More details on Intel 4
The use of EUV lithography in-depth is something to note in the Intel 4 nodes. Intel claim as much as twice the high-performance library space scaling when compared to the Intel 7. The Intel 4 will also be suited to the EMIB and Foveros packaging and applied sciences. With Intel aiming for over a 20% increase in clock speeds, we can expect 6GHz on higher-end CPUs.

The die shot shows the compute tile of a 14th-generation Meteor Lake-P cell chip. It has six P-cores and eight E-cores and employs the previously mentioned Intel 4 node. The CPU will also have an I/O tile, SOC tile, and graphics tile, with the latter expected to use TSMC’s N3 node. According to previous rumours, the desktop CPUs will indeed require a completely new LGA 1851 socket rather than LGA 2551.
