Opinion on the 11900?

[Och]

Not the 11900K, but specifically 11900. It is listed as a 65w part, vs 125w for the 11900k. It has hyperthreading and the rest of the features of the K model, except for overclocking, which is getting relatively irrelevant lately.

The biggest difference seems to be 2.5ghz vs 3.5ghz base clock, but turbo frequencies are within 100mhz of each other. I am trying to understand what is the catch here? My main priority is the 65w, as I like to stick with a low profile Noctua cooler. I understand that the K cpus that are listed at 125w can often consume over 200w, is this also going to be the case for the 11900 when running at full turbo frequencies?

If it can continuously turbo in the same way the k model can, there will be little to no difference. The trick with Intel platforms is figuring out which restrictions they have built in.


Be wary of things like limiting memory speeds too.

I just read up some info, and it turns out that even a 10700 can consume 225 watt at full turbo, which means the 11900 can consume even more. This is utterly misleading for intel to list it as a 65w part. I built a computer for a close friend last year, using the 10700, and thinking that it is a 65w part I used a Noctua NH-L9x65, which is a small, low profile cooler. I hope they dont have issues down the road.

 

[Och]

Just did more reading, and it seems ryzens consume half the power of comparable intels. I guess its the 14nm vs 7nm. No way I am upgrading until intel gets 7nm chips.

From my short time with a 10900F, I can say that you can definitely override the power limits, but as far as I can tell you can't override the boost frequency limits (whether directly, using MCE or any other method).

I briefly had a 10900F drawing 500w of power in Prime 95 small FFTs. That was way beyond the standard power limit for the processor and I maintained it long enough that the short term boost should have expired. It ended up being throttled by the motherboard VRM overheating, not the standard power limits. Obviously due to the absolutely insane power draw, and the fact the VRM was bordering on overheating, I didn't maintain that for more than a few minutes.

Unfortunately, in things like gaming, the load on the CPU isn't actually that extreme and you're not that heavily power limited. In that situation overriding the power limits by itself while not being able to adjust the boost frequency just doesn't help you that much.

Personally I would not recommend any of the non-K parts unless you absolutely don't intend to overclock, and by overclock I include even using MCE (sets all core boost equal to single core boost).

They shouldn't have any problems if for no other reason than the CPU will throttle down if it starts overheating. If you didn't override the stock power limits the CPU should also drop down close to its rated TDP after about 120 seconds, if I recall correctly.

AMD Ryzen CPUs are arguably more "honest" about their TDP limits, since they don't have a short term limit where the CPU can exceed its rated TDP.

Problem is people think that Intel = heat, but in my experience the only time that was true was when using Prime 95 and insane settings.

For me my AMD is actually hotter, but undervolting at least seems to fix it a little.

 

[KAC]

AMD runs way hotter than anything I have used from Intel.

 

[acroig]

I can't say that I have stressed my 10900KF much yet by at 5GHz temps are in the upper 60s under load.

 

[KAC]

After using a 10700 non k I really think people oversell the overclocking crap. The processor is pushing the Gs just fine and taking names.

I would assume Intel is binning chips and those that barely make the cut are locked and the rest are the Ks?

Yup think so. It runs 4.7 Gs all core. Can’t complain. Yes 5.1 Gs is better but in real world gaming at 1440P I can’t tell a difference.

Agreed. I keep laughing at the thought of Intel now being the value CPU.

 

[Nunz]

Ah, good to see the veil of "Intel runs hot!!" Is finally being washed away

 

[Och]

So wait, a Ryzen at 120W can be running hotter than Intel at 220w? How is it even possible?

 

[Och]

Which memory would you guys get for a 11900/k? Intel lists it at 3200, and in my experience in the past with skylake/coffee lake, which ran anywhere from 2333 to 2933, it was difficult to overclock memory to anything over 3200. On my wifes 8086k, the system is unstable if I select XMP profile which sets the memory to 3200 and overclock the CPU at the same time. If I run the CPU at default clock, then I can set XMP.

So if 11th gen Intels support 3200 default memory speed, its probably better to go with at least 3800? What is the popular choice these days?

 

[acroig]

I have 3600 running at XMP. KAC has his to 3733 (I think) and Nunz 4000?

I was just looking at newegg, and it seems that there is a pretty wide spread in pricing for different memory at the same clock. For instance, 32gb of 3200 can be had for $150 or over $300, even from the same brands. And there are so many brands and models, how do I know I'm getting quality parts?

Well the thing with RAM is what chips does it have and how well they OC, if that's your thing. Also, you want say 3600 but with as low timings as possible. Lots of choices.

Others here (Nagorak, Nunz) can assist with RAM much better than I can.

Are you speaking about their current CPU or your previous experience? guru3d's 11900k review shows Amd 5800/5900 uses less power per core and package than intel. Anandtech and tomshardware handbrake test also show intel consuming more power. How does Intel higher total power package end up running cooler than AMD 5000 cpu?
