Intel moved to a hybrid x86 CPU design for its eleventh hour of Core processors (Alder Pond). No longer most effective that, however the corporate additionally made a number of alternative adjustments to alternative elements too, dubbed the “Uncore” portion of the processor, additionally known as the Gadget Agent, which contains the Northbridge. One such alternate is it appears inflicting numerous latency problems and gradual efficiency on the whole on Intel’s hybrid chips in keeping with a record by way of YouTuber Tech YES Town (TYC).
TYC, mentioning trade resources with wisdom of the subject, explains that the infection, it appears, is a aftereffect of the “I/O driver” of the uncore (Gadget Agent) that was once allegedly moved off the CPU on Intel’s twelfth Gen and thirteenth Gen chips.
The use of latency checks, TYC displays that the infection is particularly pronounced on Home windows 10 typically. Even supposing Home windows 11 isn’t totally excepted to those efficiency quirks, Microsoft and Intel’s blended efforts on optimizing Story Director for the hybrid processors do repay in a few of these instances, despite the fact that era gaming efficiency numbers have no longer urged the similar.
Within the description in their YouTube video, TYC writes:
I at all times idea Intel’s CPUs have been snappy, actually that have been the snappiest of snappiest, even vs Ryzen, the place AMD have stepped forward a dozen over time with their latency. On the other hand with the appearance of twelfth gen Alder puddle and thirteenth Gen i9-12900k and 13900K CPUs respectively, Intel took one thing AWAY, and that was once they moved the I/O driving force immediately off the CPU (that’s what I used to be informed from more than one resources), and this was once the precise reason latency problems had been happening on those CPUs for home windows customers
To bring to check and perceive the validity of the perceptive residue they felt, TYC when put next their tenth Gen Core i9-10850K (Comet Pond-S) with the Raptor Pond-S i9-13900K (thirteenth Gen). In some instances like DPC (Deferred process name) latency, the efficiency is similarly malicious on each Home windows 11 and 10, despite the fact that nonetheless, the Home windows 10 device does do worse. This is smart as DPC is immediately alike to driving force dealing with potency and a few a part of the I/O is concerned.

Alternative instances like dragging and losing MP4 recordsdata and abruptly opening MP3 recordsdata in Adobe Premiere Professional additionally show off needy appearing at the a part of the more moderen Raptor Pond CPU.

One of the crucial efficiency variations unhidden right here may additionally need to do with the core-to-core (c2c) latency variations in Raptor Pond in comparison to Comet Pond.

As you’ll see within the pictures above, courtesy of AnandTech (1,2), the c2c latency varies reasonably a dozen at the hybrid Intel 13900K in comparison to the 10900K. The c2c at the 10900K varies from as little as 5.6 ns to as prime as 23.8, future that at the 13900K is any place from 4.0 ns to 53.9, and the latencies between the E-cores are particularly malicious.
