Why does a 10900K FEEL faster than a 13900K?
- Thread starter RavenXXX2
- Start date
When I brought this up awhile back I got some what I can only call "special" replies in response :s
It is why my main productivity desktop I'm sticking with my X79 1650 V2 (that and newer hardware needs Windows 10/11
) and the laptop I use for productivity is a 10870H instead of something newer.

Not watching the video, but is it because that chip stock is pushing as near to the maximum data flow as Intel’s current ringbus design can handle with two memory channels?
Edit: Or could it because Intel don’t have the glue to bound Skylake to Atom and Atom mesh architecture has some pretty bad disadvantages?
Edit: Could it be because you have to pass Intel chips through more layers of abstraction for the OS to figure out what it’s is working with?
Edit: Or is it a combination of issues?

If you're not going to watch? Why comment? And AGAIN with the "glue" + "skylake" + "atom" thing? You are a broken record.

I feel like LTT did a video similar to this before? Sorry if those videos are LTT but got no tube access
He doesn't know why, but it's something that was commented on a lot back when Ryzen was a new thing, because it also had higher latency (especially the first 2 gens, I think the newer Ryzens are less so).
11th-13th gen use a different architecture, I don't know why you keep calling it Skylake, since things like this prove it is not the same

What's with the stuttering on the desktop?
You don’t say. That’s a topical comment to make, one that’s been pretty well disused many times. Think of a big + little core mis-mash as a work around to overcome other problems. You have accept some compromises with this format. Seems this YouTuber has come across compromises.

If you couldn't be bothered to watch the video I am a little surprised you think you have anything of note to contribute to this thread other than your general anti Intel diatribe and conjecture you've posted on many previous occasions. I did watch the videos and the TYC contributor was not sure himself as he is "not a CPU architect".
From my own experience in using both those architectures I don't get any such slow downs but I am using tuned DDR4 in Gear1 on Raptorlake so I would be looking to rule out slowish DDR5 (which is always Gear 2) with a notable increase in latency as the main contributory factor for his issues.

Its a IOH thing, on older chips like the 10900K the IOH is on the CPU, with 12'th, 13'th and as it will be with 14'th gen the IOH is on the motherboard, that's what's causing the high latency, its also what's causing stutter on the desktop.
The stutter....

So its the windows scheduler then? Needs more updates.

Now if you'd bothered to watch the videos you would have seen him say that he disabled E-cores and still had the same problem so nothing at all to do with "big + little core mis-mash" you're trolling about.
Overclocking the Ringbus helps abit, i did this on my 12700k to get it as close as possible to my cpu speed. But at the end of the day the e cores will hold you back unless you can push those further.

Watch the video's, turning the E-Cores off makes no difference, they tried that, its because the input controller is on the motherboard with 12'th and 13'th gen.
Think about it, the thing that's controlling all of your inputs is not a part of the CPU, its a separate chip on the motherboard, so every time you action your mouse the signal is sent through the motherboard security before it reaches the CPU to be processed, with the 10900K or older, down to Sandy Bridge, and Rysen the IO input controller is on the CPU.

Can i assume the motherboard chipset controls the Ring bus then? Never looked into it aside from overclocking it.

Probably fine, yes ^^^
No the Ring Bus is what's controlling cross core communication, that's what makes games run faster, more so than IPC, because Windows likes to switch cores randomly for no reason every time it does that the game waits on the CPU, that results in higher frame times, lower FPS.
Intel came up with a faster CPU intercommunication network which they called the Ring Bus, Sky Lake i think.
Even the Ring Bus is not all that anymore, its been surpassed ironically by AMD's Infinity Fabric, the thing Intel called "Glue"
The IOH controller is the thing that controlles your keyboard, your mouse, your joystick.... they moved it off the CPU, presumably to save space on the CPU package and farmed it out to the motherboard vendor, made them take the cost, the result is the IOH is much further away from the CPU and has a lot of motherboard circulatory to go through, that's what's causing the lag, lag being a delay, delays can also cause a backup bottleneck of data and then you get stuttering.
