Intel 4 Node Will Double Density And Increase Clocks 20% Simply In Time For Meteor Lake

There are two components to creating a microprocessor. That is clearly an oversimplification, as a result of there are literally a large number of components, however the two highest-level are design and fabrication. It is all effectively and good to design a ludicrously-fast, bleeding-edge processor, but it surely makes little distinction if the fabrication course of used to construct it goes poorly and you find yourself with a chip that clocks half as excessive as you deliberate, and even worse, has horrible yields (that means that a lot of the chips do not work).

Intel’s CPUs within the final decade or so have knocked it out of the park on the design facet of issues, however the fabrication facet confronted severe struggles when making an attempt to maneuver from the older 14nm course of—used for every thing from Fifth-gen Broadwell as much as Eleventh-gen Rocket Lake—to the newer 10nm course of that’s now often known as “Intel 7.” The issues slowed Intel’s progress within the efficiency area to a crawl, and allowed competitor AMD to catch up from a severe drawback.

Effectively, on the Very Massive-Scale Integration (VLSI) Know-how Symposium, which has been held since 1981, Intel’s presenting 13 completely different papers, most of that are supposed to quell nervousness over the corporate’s next-gen fabrication course of. As a abstract, the corporate claims its “Intel 4” course of will provide a 20% clock fee increase over Intel 7 on the identical energy, whereas reaching double the transistor density for logic, though SRAM density solely will increase by 23%.

Intel accomplishes these achievements by making in depth use of Excessive Ultraviolet (EUV) lithography—the primary Intel course of to take action. That makes them a bit late to the sport, as TSMC and Samsung have each been utilizing EUV for a couple of years now, though you could possibly argue that Intel’s continued competitiveness on its Intel 7 course of finally bodes effectively for its future efforts.

By way of energy consumed (and thus warmth generated), Intel says that its Intel 4 course of gives a couple of 40% enchancment on the identical clock fee versus Intel 7. With that in thoughts, it appears like Intel 4 will probably be a specific boon for low-power and laptop computer chips, but when we take a look at the graph, it additionally appears like Intel 4 may provide a lot larger frequency scaling for high-powered desktop components.

As we already knew, the primary merchandise to be produced utilizing Intel 4 would be the firm’s forthcoming 14th-gen Meteor Lake CPUs. Primarily based on what the corporate has proven, we’re anticipating to see these chips crop up in laptops earlier than they seem on the desktop. We have already seen Meteor Lake in its disaggregated silicon glory, and the corporate says it has samples up and booting Home windows already, so they might come shortly after Raptor Lake, early subsequent yr.
