Intel Alder Lake CPU rumors and leaks: Big changes coming

Despite the fact that Intel simply introduced its Rocket Lake-S desktop processor, eyes are already turning to what Intel has subsequent up its sleeve: the next-generation CPU code-named Alder Lake, anticipated earlier than the top of 2021. The most recent Alder Lake leaks, provided by Videocardz, recommend that Alder Lake will characterize a pointy break from present Intel designs, for higher or worse.

Final 12 months, Intel confirmed that Alder Lake existed, and that it might ship in 2021. Initially, nevertheless, Alder Lake didn’t appear to be that huge of a deal. It’s constructed upon the identical mixed-core design as Lakefield, which shipped in 2020 because the 9-watt Intel Core processor with Intel Hybrid Expertise, contained in the Samsung Galaxy Guide S. Evaluations known as the Galaxy Guide S efficiency anemic, and extra of the identical was anticipated from Alder Lake. 

Now it seems like Alder Lake could also be extra fascinating than we thought. Let’s have a look at the highlights of these leaks.

Considerably extra efficiency

Over the weekend, VideoCardz said it had obtained a leaked Alder Lake presentation, which guarantees that Alder Lake will supply 20 p.c extra efficiency in single-threaded purposes, and greater than double the efficiency in multi-threaded workloads. Partially, that’s as a result of Alder Lake will probably be manufactured on a 10nm manufacturing node, Intel’s most superior.

The leaked presentation gives inadequate context for deciphering the efficiency claims. Videocardz urged that Intel could possibly be evaluating Alder Lake in opposition to Rocket Lake, or Intel’s 11th-gen Tiger Lake components. Nevertheless, Intel might conceivably be evaluating Alder Lake to the anemic Lakefield—through which case, the bar is ready a lot decrease. 

Intel itself has indicated that Alder Lake is being designed with efficiency in thoughts. “We’re advancing our hybrid structure considerably with a give attention to efficiency,” Raja Koduri, senior vice chairman, chief architect, and basic supervisor of Structure, Graphics, and Software program mentioned in August at Alder Lake’s official tip-off on the Intel Structure Day. 

Koduri mentioned then that Alder Lake will mix an unknown variety of performance-oriented Golden Cove CPU cores (much like Lakefield’s Sunny Cove), with an equally unknown variety of low-power Gracemont CPU cores (successor to Lakefield’s Tremont cores), with extra emphasis on efficiency. If the VideoCardz presentation is correct, Alder Lake may have eight of every.

The presentation additionally reveals Alder Lake with Intel’s XeLP GPU inside, which Intel additionally talked about final 12 months.

Word that whereas the presentation doesn’t particularly check with each desktop and cell components, it particularly identifies Alder Lake-S, implying a desktop processor. As a result of Lakefield was a cell chip, that most likely means Alder Lake will probably be out there for each laptop computer and desktop PCs.

DDR5 assist is right here

If the leaked VideoCardz presentation is correct, Alder Lake will even be the primary Intel chip with assist for DDR5 reminiscence. Intel has already made some fascinating tweaks with Rocket Lake S, supporting a “Gear 1” and “Gear 2” timing within the DDR4 reminiscence that Rocket Lake makes use of. (We describe what this implies in our Rocket Lake FAQ.)

Specifically, the leaked presentation says that Alder Lake-S will support up to DDR5-4800 and DDR4-3200.

DDR5 was first introduced in 2017, designed to be double the density and double the pace of the DDR4 reminiscence in use at this time. In actuality, it seems that when you take DDR4 reminiscence and DDR5 reminiscence and run them each at an equal information fee of three,200 megatransfers per second, DDR5 will truly ship a efficiency enhance on the order of 1.87 occasions that of DDR4, in response to a Micron white paper (PDF)
