Intel Core i9-14900KS Draws as much as 409W at Stock Speeds with Power Limits Unlocked

[BoggledBeagle]

I wonder if the chip in my 14900K is aware how lucky it is to end up in my system running nice, cool and efficient at 5.2 GHz, and not 1 GHz quicker as in the chipmelter edition CPU!

 

[InVasMani]

You can run a 128core EPYC at 360W, that's 16x more (real) cores

Hardly the same price range however.

 

[marios15]

So the price range dictates how much power a processor should consume?

Presshot all over again, pepperidge farm remembers!

Totally missing the point. Threadrippers are 350w. Its amazing what another can do with that wattage.

 

[pavle]

I'm not at all surprised; 14900K is a 350W CPU if we're honest. It's got the intel disease alright. Incurable at the moment.

 

[Random_User]

Well. I hardly see that guy in this thread, who was telling recently about how "hot" Zen4 CPUs are

 

[Vayra86]

Totally with you. I overclocked my AthlonXPs back when overclocking would turn them into the equivalent of a CPU that would cost at least a couple hundred $ more. I did it with my A64 X2 and even my 2500k, just to see what's readily available. Past the 2500k, I wasn't even curious anymore.

Yeah similar experience, I tried one last time with 8700K but honestly, undervolt is where I ended up. There's just no point to it.

So irony has it intel's top parts are best used by clocking down and doing less for their money at this point.
Nice. Why don't you disable E cores while you're at it! More megahurtz on your glorified octacore now

Tired of people assuming tuning the top tier chip is stupid or somehow worse than buying a lower tier bin that's slower in all respects. A higher bin will tune better even at the same power limits.

People aren't assuming, its a fact. I'm sure it'll tune a little better. You'll have paid that performance thrice over though. There is simply no real economy behind those parts. Its 'can do'. Not 'make sense'.

If people want to buy ridiculous products power to them. But there's also power to others to laugh at their idiocy, because opinions.

Now, if you're buying this chip to set records and are actually working at that, hey, that's a different story. But that's not what a lot of owners do. They're just epeening, and they deserve every bit of laughter pointed at them.

I'm getting P4 EE vibes.

I would guess any motherboard with two 8-pin EPS.

Each 8-pin EPS is 225 W.

8 pin EPS can handle up to 336W, but even then there are boards that cannot handle this much power, this person had a Z790A-D4, that has two 8 pins, and he was able to pull 500W+ on the CPU before the VRMs blew. I wouldn't trust a VRM that blows at 500W, to handle 400W.

 

[sethmatrix7]

Has Intel just not learned that people dont want high wattage CPUs?

They know that but in this case have to produce the highest performance possible, and due to the inefficiencies of their architectural design this is the result.

Why is 14900K a 350W CPU?

 

[Broken Processor]

Wow my GPU over clocked doesn't use as much juice. This pig will be the feed for only the most enthusiastic Intel fanboy.

 

[matar]

Good CPU for winter cold days.

Absolutely no one should be throwing stones at you for running your hardware at a performance level and power consumption you want or need. I am not saying that you are, but no one should throw stones at someone for running their hardware at a performance level and power consumption they want or need regardless of the obscenity of the overclock. If someone can afford to and wishes to buy this and run it with P cores only, no hyperthreading, and maximum clockspeed and power consumption that's fine.

I am not willing to buy hardware like this but it would be fun to push the performance as far as it will go.

I mean, I'm ready for stones thrown for thinking that overclocking is pointless, and for saying that I much more prefer modern CPUs that run to the max out of the box, with the ability to be further limited if cooling is restricted. I don't miss tinkering in the BIOS for that extra 100 MHz one single bit.

I do. 6+GHz is awesome without nitrogen. Probably absolutely demolishes single threaded jobs. Would love an HEDT platform that can do it (especially at the price level), because I do love me some full 7 slot motherboards (like old school X79, X99 and X299 ASROCK and ASUS mobos). There was one option out there for HEDT but I wasn't able to buy it because the boards currently seem to be $1000, let alone the $1000+ for the CPU even years later. I'm still looking for the highest TDP/Wattage Xeon E5 V4 out there (P variant) for example. I just like hardware. I thought that was the point of this site and forum. Plenty of other options for various budgets, power limits, specific uses, etc. That's the best part of the PC world. Heck, there's a big wide used market too (most of my stuff is used).

Hey more power to you but for me, money is limited. My electric bill is already $500 a month for a 900sq ft home. I dont need to be adding more on top of that.

The cost of SMT is far less than its detractors think. The designers of the unreleased EV8 with 4-way SMT reported a 6% increase in die area over a single threaded equivalent. This was over twenty years ago and today the cost is likely to be even smaller. SMT is useful in the case where IPC is low due to low cache hit rates or other non-execution related bottlenecks.

Sure, better prefetching is just a side effect of having more threads = more prefetchers = more chance whatever the current app needs already got pushed into cache, but you can also just have a wider/more aggressive cache prefetcher with no SMT in mind. Also that 5%-6% was for a single core proessor -- let's say it increases the per core area of modern processors by 3 or 4%, now let's say we have a 10 core chip... a 20 core chip... it's not huge but it adds up - especially when you're cutting a million units.

Now let's say an e core is 15% faster than a logical thread that relies on gaps in the pipeline... and for that space savings you could have added more ecores.

I don't think the intel engineers would have made the decision to ditch HT if it wasn't something that was going to give them a noticeable advantage. And given that they are trying everything and anything to increase performance, I think this has a chance to be real innovation.

That'd be the Binford 9000, Tim.

This is perfect, I’m totally getting this bad boy. I’m going to delid it and plop it in my loop that’s hooked up to my Mo Ra3 420 PRO which is in my boiler room where I have my home’s heat pump. Now I got a great heat source for the heat pump

 

[Dr. Dro]

Not significantly different from the 13900KS but I seriously wonder what's the point of ever releasing this CPU. It's... senseless in every way, it just accentuates the critical issue with the 13900KS and 14900K CPUs, which is that power draw. Just... nope. I'll take the up to 200 MHz hit and keep my processor.

Practical and elegant. Intel Inside.

Practical and elegant. Intel Inside.

I genuinely get the appeal, however, I'm fully aware that you cannot even come close to running this processor to its fullest on conventional cooling.

 

[MaMoo]

This winter, be prepared for the worst. With the new Intel 14900KS, you will be cozy and warm. It has so much utility that it can heat your home, make you tea, and bake those xmas cookies. It is an appliance on a chip!

This message is approved by your local electrical utility company. Get Intel. Get Warm.

 

[Redwoodz]

Ok someone has to hook one of these up to their loop and see what it can really do. Only $95

Prefetching is only one example and that is from the Northwood days. SMT is most useful for workload with low utilization of the functional units or in other words low IPC. OLTP databases are a good example.

If Intel has ditched SMT for newer architectures, it certainly isn't due to performance reasons. Rather, the primary driver would be slightly simpler validation and reduced attack surface for code in shared environments, i.e. cloud providers' infrastructure.
