Intel begins high-volume production of Intel 4 node chips this week

pcgamer.com:

Intel is set to begin high-volume manufacturing of its Intel 4 node with bleeding edge extreme ultraviolet lithography (EUV) in Ireland from Friday the 29th of September. It will host a ceremony at its Fab 34 facility near Leixlip, Ireland at 12:45pm Irish Standard Time. Intel CEO Pat Gelsinger will be in attendance.

Though it's not the first facility to begin Intel 4 production (it's already underway at its D1 fab in Oregon), it is the first in Europe, and the wafers and dies it produces will end up in upcoming Meteor Lake processors. Specifically, Intel 4 is used to produce the compute tiles of Meteor Lake CPUs, which contain P-cores (Redwood Cove) and E-cores (Crestmont).

Intel 4 is a big deal. Intel has projected that it will allow a greater than 20% increase in clock speed within the same power budget over Intel 7. That's a key figure for laptop use cases. Higher performance is great, but battery life is all important too. Of course, smaller dies allow Intel to achieve higher yields, with more dies per wafer.

EUV is a key pillar of Intel's aggressive process roadmap, allowing it to aggressively produce five nodes in four years, the first of which is Intel 7, as found in 12th Gen Alder Lake, 13th Gen Raptor Lake and upcoming 14th Gen Raptor Lake Refresh CPUs. Intel 4 is all but in full production. It's to be followed by Intel 3, a refined version of Intel 4. Arrow Lake, the next desktop chips we'll see, will be built with the 20A process. They're likely to launch some time in the second half of 2024. This is the point at which Intel expects to achieve process parity—if not leadership—over its semiconductor rivals. Finally, there's 18A, which is due to begin production in late 2024.
