Big Little processors from Intelcomprising the twelfth generation (Alder Lake) and the thirteenth (Raptor Lake) and essentially combining high-performance and efficient cores in the same package have garnered much praise for delivering gaming performance. However, some users may not have noticed an improvement when it comes to performing other heavy or even trivial tasks, but may also notice that their latest generation device is less responsive.

Was the commitment to hybrid architecture a mistake on Intel’s part? Indirectly, that’s the question that Tech YES City’s YouTube channel tried to answer, providing some data related to the latency of the Intel Core i9-13900K compared to the Intel Core i9-10850K.

Probably to the surprise of some, Core i9-10850Kbelonging to the Comet Lake generation, it has been shown to have lower latencies and better responsiveness when working with files using the Adobe Premiere Pro video editor In terms of performance, it is clear that Raptor Lake wins hands down, but this is not the aspect that the YouTube channel wanted to compare.

Raptor Lake’s higher latencies may be due to several changes that Intel has made to various related components, which are called Uncore or System Agent (System Agent) and between which is the North Bridge. Tech YES City, citing various sources, explains this perhaps the origin is that the Uncore I/O controller was probably removed in the twelfth and thirteenth generation Intel Core processors.

This can be seen in the graphs published by Tech YES City Both Windows 10 and Windows 11 have the same issues with deferred procedure call (DPC) latency, although the situation of the former seems to be somewhat worse. On the other hand, since this is a problem directly related to the processor, it cannot be ruled out that it could also affect other operating systems such as Linux or FreeBSD.

Tech YES City acknowledges that its video is niche, but it’s equally true that it points out a problem that even end users doing things that are at least relatively common may notice. We will see if this content is answered or confirmed by others and if Intel decides to take note for future generations of its processors.
