SNAP - The Intel CPU Latency Story (Part 1 of 2)

I always thought Intel's CPUs were snappy, in fact that were the snappiest of snappiest, even vs Ryzen, where AMD have improved a lot over the years with their latency. However with the advent of 12th gen Alder lake and 13th Gen i9-12900k and 13900K CPUs respectively, Intel took something AWAY, and that was they moved the I/O driver directly off the CPU (that's what I was told from multiple sources), and this was the exact reason why latency issues have been occurring on these CPUs for windows users, not the e-cores or the p-cores.

I am having an I/OO - Input Output Overload.

[MarcoGPUtuber]

I am proud to say that I have witnessed the Intel latency problems first hand when you were editing vids in Taipei.

[JadeIsler]

+rep tysm for making this. I always tune my systems for minimal latency, but even with all the tweaks I still find my 12900K less responsive than my old 10700K. I always just thought it was windows 11 but it's nice knowing neither of us is tripping.

[hateWinVista]

This is amazing, not a lot of techtubers really talked about latency and real user experience.

[valuehunter]

In part two could you add some latency metrics? Maybe compare AM5 to 13th gen vs 10th gen

[thefutureisnotset]

Very well articulated, i have always eerd towards low latency than higher bandwidth from my enthusiast and budget conscious perspective. Responsive is king. Like frametime vs max fps, lol. Looking forward to Part 2

[JRose-zniw]

I have both a 10900K and an 11900K (yeah I know) and have no plans on going higher up the series for reasons as this, and temps...great topic.

[GregoryShtevensh]

That was super interesting! Can't wait to see more of this kind of content

[wingmanemu]

this is a great video. this is why i love this channel. theres so many intricacies in tech that people have to dig really deep to find answers for why things dont work the way theyre supposed to, and now my next upgrade from my old i5 6500 will be a 10th or 11th gen intel cpu instead of any of the newer 12 or 13th gen

[shieldtablet]

It is extremely unlikely the problem you describe is the cause. At most, it could be an issue with buffer sizes or some other bug in the implementation. The ns of latency added would not cause seconds of delay.

[ImWateringPSUs]

Truly a great video! I noticed the exact same thing, I was kind of expecting it when I saw the hybrid design of LGA 1700 but I didn’t thing it would be this bad. The video was an eye opener because up until now I genuinely thought it was just due to the e-cores. Turns out, intel ditched the ring bus architecture that made them so much sales and appreciation. At the moment I switched to a 7000 series Ryzen (going AMD for the first time after having intel my whole life, I switched to a first gen Ryzen when they just came out but quickly backed off) so we’ll see how it goes!

Two Tech YES Videos in 24 hours! The drought is finally over! May it rain YES!

[WillbmeEVA]

This video really makes me sit back and do some deep thinking about what takes priority with the latest and greatest tech. Thanks for perhaps finding the needle in the Cheese Cake. I will certainly be awaiting the release of episode 2.

[Zakmakoto]

Now this is very interesting, i just went from an 8700k to 13700k, upgraded almost everything including the nVME SSDs to gen 4 and i was puzzled by the feeling of it being less responsive and laggy than my gen 3 and 8700k and despite a crystaldisk mark showing superior bench results. Thanks for the finding!

[misplacedmodifier]

This 'dragging and dropping' thing, for me was just an unexplained annoyance (I'm running an I5 12600K) - so thank you for this very comprehensive and clear explanation.

[BOTPlayingBlackOPS]

yes, it's true. I am always about feeling how fast a PC, Car, or how is Sound in my audio installs! so Yes, some latencies in some software are affected, and I can tell when it even comes to gaming! Awesome video, thanks!

[jacksonbtb]

This is quite interesting. I have not used a 12th or 13th gen intel platform myself, but this reminds me of when people upgraded from x99 to x299 and saw a performance decrease in some areas. This was when intel changed their architecture from ring bus to mesh (i think). At the time, i'm pretty sure the consumer kaby lake chips were still on ring bus and actually outperformed the HEDT cpus in most games.

[DamienRamirez]

I have a 12900KF, seen the issue you show, I always thought it was a Windows 11 issue, because it started happening after a KB update to fix a security issue last year or prior. Long story short I disabled A LOT of stuff in windows, MPO was one of the main ones & I wouldn't say I stopped having the issue, but it wasn't even closer to as nearly as noticeable today since I reinstalled windows fresh (due to MBR on new drives for some unknown reason causing CSM disabled issues, causing black screens for monitor that wont go away unless you restart with HDMI old TV installed into 3080 GPU with the DP port monitor) Since Then! I notice that latency issue Every God Dam Time. ~ Hindsight wish I kept a list of the changes.

[teddp]

This is very interesting. I had no idea that such an issue even existed I'm glad that I got my 10850k which I'm still using. I believe that you Brian are the first who comes forward with this problem hopefully more technical YouTube channels will pick it up and increase the awareness of this issue which will force Intel in the future to fix it.

[deaddeyedante]

This was great, Brian! Thank you.

God bless.
