Core i9 11900K/KF disscussion

I just want to know everyone's general thoughts on this monstrosity hitting 98C with a 360mm AIO and being able to eat up to 250 watts!

As much as I despise intel, this is just sad to see that it's gotten this bad. I hope Pat Gelsinger can bring them out of the hellhole that they dug themselves into. Though, there are rumors that intel will manage to compete and even take down AMD with Alder and Meteor lake. It's also rumored that Meteor lake will have 3D stacked dies, which will be quite exciting to see in my opinion.

 

Intel hasn't been innovating very much ever since they have had a CEO who has no technical skills. Executives in companies that innovate technology should have some technical skills so they understand what's going on, and can do proper project planning around that knowledge. I'm glad Pat Gelsinger is now at the helm, because he's going to turn things around.

As for the i9 11900K, that thing is the pinnacle of Intel's 14nm CPUs, but is very innefficent. The underlying architecture was never meant to be on a 14nm node, so the backport ruined things a bit, and the surface area per core is not enough to properly cool the chip. Intel needed to make wider cores for this release.

As for Meteor Lake's stacked dies, I'd rather see the cores placed next to each other horizontally. Vertical stacking will make the chips harder to cool. If the target is maximum single core performance, we need a large surface area per core to provide the proper cooling potential for high frequencies. Single core performance is still king and will continue to be for quite some time for the majority of people, especially gamers.

 

They should eat the L and start putting L4 cache on CPU's again

 

Well said. The 11900K is definitely gamer oriented, especially with it having 2 less cores than the 10900K; however, if priced right it could be pretty competitive and still make a nice splash before they exit the 14nm train for good. Core count isn't everything, especially for when it comes to gaming.

I must say though despite the obvious of Intel completely getting spanked recently by AMD, what they were able to do with the 14nm process is quite impressive.

The good thing that came out of Intel's complacency is a lesson that can be learned by others ...

 

I'm looking forward to Alder Lake hitting desktops as it means I'll be able to get a CPU from that family in a future revision of the Clevo X170.

I see a lot of people complaining and bashing Intel because they think small cores are stupid for desktops. I have to strongly disagree with this sentiment though, because there is no reason to waste power on a high performance core to browse the web or to do other light tasks. Power efficiency matters even on desktops since electricity isn't free, and even desktops have a limit to cooling capacity. Furthermore, this increases the efficiency of the CPU, which can lead to a further increase in performance.

Case in point, games that can exploit a hybrid architecture will get performance improvements as well, since light tasks can be run on the small cores exclusively and heavy loads can be executed on the big cores exclusively. The power savings from the small cores would allow you to divert more power to the big cores so they can run at even higher frequencies for enhanced performance. Alder Lake is very gaming optmized.

 

I'll add on to what you said.

It also seems like people think Quadcores are really, really bad. No, a lot of games still don't utilize more than 2 or 3 cores. I've seen many comparisons between the Core i5 9/10300h and the i7 9/10750h, and the performance difference is close to the margin of error. If you look at the 11th gen mobile i7's with XE graphics (can't remember the names as they are strange,) you can see they still put up a great fight compared to AMD's mobile offerings. I think one of the good things that came out of them being stuck on 14nm was being able to create a low TDP Quadcore with insane single and multi-threaded performance. I believe that the saying "Games benefit more from fewer faster cores than more slower cores" still partially holds up. Are there games that still use only 2 or 3 cores? Yes. Are there games that are starting to utilize more cores? Also yes. Will Quadcores still hold up in the future for gaming? Absolutely, but 6-8 core processors will definitely outlast Quadcores in the future.

 

For 60Hz AAA gaming, quad cores with HT/SMT are still mostly fine. For high refresh rates, they are obsolete.

 

Even for higher refresh rates, quad cores still do well as long as you only play FPS games. My i7 4930MX still does very well in this area.

My i7 7700K is barely able to do 120 fps in newer open world games or not at all depending on the title. Quad cores are definitely obsolete for open world games.

Having said that, newer octacores will give you significantly higher 1% and 0.1% lows, so they are objectively better, and should be what we all get for our next system.

 

Depends on the shooter. For large-scale multiplayer FPS and BR games with AAA graphics, quad-cores show their age.

 

Put it the other way. With half of the chips filled up with small cores it will never be able to provide max or more performance (limited by smartphone cores). Not a good idea limit cores or its max performance for browsing the web. You lose potential more performance from the chips. And Intel's coming high performance desktop processors will come from mobile processors. Not the opposite. Would you build a bigger engine from a small weak one or the opposite?

 

I suppose that depends on cost, power output, and efficiency, but I'd say probably not. It would be better to have a separate architecture for a high performance engine.

I get the point. I'd still give the hybrid architecture a shot though since it seems interesting. We'll see where things end up in September.

 

Intel is in another Pentium 4 debacle from what I can tell. They just keep pushing their old architecture to new limits.

At least I hope they can make a comeback with something actually innovative. Perhaps some Itanium-derived design? Not sure what else they can pull out of the magic bank accounts
