Core I9 14900KF Breaks World Record, Almost Achieves 9.1GHz (2023)

[tomohelix]

Look to me a significant amount of engineering went into making sure the chip can withstand the amount of power it is drawing. Basically a desperate move by Intel to keep their outdated design from being completely smoked by AMD.

[nolok]

Much better than the time just a few years ago where they tried to show a 28 core 5ghz chip and pretend it was a normal one and got pissed when enthousiast realized they were using insane cooling to get it there.

I'm still baffled by that showing years later. Over-engineered, over-cooled chips to reach absurd speed record has been a staple since as far as I remember, like back in the Pentium 2 or before. Why did anyone at Intel think they should hide the sauce, or get pissed when fans got to it, is beyond my comprehension.

[NoPicklez]

Not at all really.

The 9Ghz clock was achieved not through any normal cooling or by efficiency of the chip.

These overclocking records have been around for decades but they're in no way shape or form representative of the average of even the top 1% of users.

It's impressive purely because it was possible with an off the shelf chip.

Intel isn't worried about AMD. They're worried about Arm.

October 2023... and that typo..

  The team was able to achieve a very impressive 9043.92GHz

[m463]

if you want to properly make light of it, you have to say 480000Ghz

(a literal joke, since visible light is 480 thz)

[sourcecodeplz]

Dunno what happened but way in the day tomshardware writers were very knowledgeable and quite witty + smart too. Guess it got sold? I can't pronounce the name of more than 80% of their writers now.

Sick overclock. It's cool to see Intel chips reach such new heights. It felt like we were stuck for 10 years. Hopefully as they get better at manufacturing and shrinking the 5GHz bar can be reliably passed.

[formerly_proven]

5 GHz in off the shelf SKUs was passed years ago.

[wutwutwat]

Weirdest headline ever. Why tell us what it almost achieved? It broke a world record, right? Well, what is that record then? Why tf is a number it didn’t hit being mentioned at all?

[bheadmaster]

The first paragraph says:

    The overclocking team from Asus has achieved a new CPU frequency world record with Intel's brand-new Raptor Lake Refresh Core i9-14900KF. The team was able to achieve a very impressive 9043.92GHz on a single P-core with liquid helium, breaking the previous world record by 35.1MHz.

Perhaps the editor thought that "almost 9.1GHz" sounds better than "over 9GHz". I disagree with both - the best would be "over 9000 MHz" [0].

One would think from far away perspective or first principles, that we have passed the point of liquid cooling being way more optimal in the datacenter a long time ago already (if you're actually doing computing and not idling).

But everything's so slow and path dependent.

I wonder how much you could do with a single rack if you got really serious about it. Cooling, power, networking etc.

Obligatory "it's over 9000!"

I’ll always wonder what would have happened if Intel had stuck with Pentium 4 and those incredibly long (31 stages! How we’ve fallen). Sure, they were power hungry, but at ~100W they don’t compare badly to modern chips. And dumping 100 Watts onto a single core is an extremely cool and fun thing to do. I wonder if we could have 10GHz processors for real by now.

[arcticbull]

Sorry, why do you say that the P4/Netburst microarchitecture doesn't compare badly to modern chips? Their performance was utter garbage (at the time, and now) which is why the Pentium M architecture (a Pentium III derivative) was used when they built out Core. AMD was spanking them at the time with the K8/Athlon 64 and the Athlon 64 X2.

A super long pipeline allows higher clock rates but it takes a giant dirt nap when branch prediction fails and when you have a cache miss. You end up having massive latencies in these cases.

Further, generally all else being equal a lower clock rate allows you to be more energy efficient.

(Edit: With modern core counts) I think we’d be seeing partnerships with GE, Whirlpool, Rheem etc ;)

[underlogic]

Waste of sand. You want liquid nitrogen on your desk? Where's the utility?

[apantel]

It’s a sport. It’s like drag racing. Nobody is going to drive a drag racer to work, but that’s not the point of the car.

[htag]

It's liquid helium, which I imagine just evaporates into the air.
