Core I9 14900KF Breaks World Record, Almost Achieves 9.1GHz (2023)
- underlogic 2y agoWaste of sand. You want liquid nitrogen on your desk? Where's the utility?
- htag 2y agoIt's liquid helium, which I imagine just evaporates into the air.
- bee_rider 2y agoAlthough, wouldn’t liquid nitrogen also evaporate? The atmosphere has lots of nitrogen.
- olliej 2y agoThe bigger issue is that helium is a functionally finite resource, and does not remain in the atmosphere (at least IIRC it literally just floats up until it gets blown into space). The bigger local issue you run into with liquid helium and liquid nitrogen is having it evaporate in an enclosed space. You can "easily" create an environment leading to inert gas suffocation (a real hazard in some industrial cases) - in reality any simple case like this is unlikely to be using enough of N or He, and is unlikely to be sufficiently enclosed, but in principle it would be possible - maybe if you were in a basement and spilled an inexplicably large thermos of them it could do it.
- lathiat 2y agoYou can definitely cause problems by spilling an entire dewer into a smaller room. Had to calculate this for the safety part of a LAN party event application. Fortunately we had a very big room.
- olliej 2y agoDewer! thanks, I knew there was an actual name for those heavy duty thermoses but it completely escaped me :D
- BenjiWiebe 2y agoDewar, actually. Originally Dewar flask, after Sir James Dewar.
- apantel 2y agoIt’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.
- arcanemachiner 2y agoWaste of cars. You want liquid nitromethane on your roads? Where's the utility?
- rgmerk 2y agoBut at least drag racing is a spectacle. Not my thing, but it is a spectacle. This? You push a button and a number comes up.
- lostlogin 2y agoBenchmarking hardware has been a thing forever, and applies to a vast swathe of things. Graphics cards, ram, hard drives, network cards etc. Then you look further and see that it’s done with coffee machines, motors (of all sorts), and just about any other device you can find, make or name. Wanting a fast/strong/powerful/quick X is a fairly common thing for many of us.
- steve_rambo 2y agoAre you sure you haven't visited hacker news by mistake? Hardware overclocking requires a decent amount of knowledge, most of it obtainable only through months of trial and error, and a lot of tuning to push dozens of often conflicting parameters just right. Extreme overclocking requires that much more. If what they're doing is simply "pushing a button", then programming and system administration can be reduced to that too, along with many other things. You simply can't get full performance from modern systems without some amount of overclocking, and things like PBO and XMP/EXPO profiles are far from what your hardware can achieve because they have to be very conservative, or many systems won't run without additional manual tuning, which most consumers won't do. (Except for closed systems like Apple's where your hardware doesn't belong to you and you can't change anything anyway.) So one immediate thing overclockers provide are general guidance on what you can expect to achieve and what thing to tune which way to get close to maximum performance from your hardware without spending months on it like they did. I heavily rely on such information. My system would be at least 25% slower if not for these "button pushers".
- gnabgib 2y agoOctober 2023... and that typo.. The team was able to achieve a very impressive 9043.92GHz
- m463 2y agoif you want to properly make light of it, you have to say 480000Ghz (a literal joke, since visible light is 480 thz)
- sourcecodeplz 2y agoDunno 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.
- fxtentacle 2y agoThe writer in question seems to be a freelancer who started working with them in August 2023, meaning he was pretty new to Tomshardware when he published this in October. Looks like the usual cost cutting where you replace employees with contractors. Also, this entire article is based on an Asus advertisement video on YouTube. I'm sure they wouldn't put their best writers on that kind of content.
- AlecSchueler 2y ago> I can't pronounce the name of more than 80% of their writers now. What does this mean? Only those with Anglo-Saxon heritage make for good writers?
- heyoni 2y agoIt means they changed from what they remember. No need to go for that low hanging fruit.

- tomohelix 2y agoLook 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.
- fortran77 2y agoIntel isn't worried about AMD. They're worried about Arm.
- arcticbull 2y agoIntel is getting attacked from all sides. AMD has raised their market share over the last 4-5 years from about 8% to 31% of x86 sales. Intel also saw 5 straight years of market share declines against AMD in the server space - which is by far the most lucrative. And yes, they're also worried about ARM and Nvidia.
- nolok 2y agoMore than half of Intel's revenue come from desktop and laptop chips, and that's the segment that's being eaten the fastest, and the one doing the eating is AMD. ARM is another threat on the horizon on that front, but it's nothing compared to the beating AMD has been giving them since the Ryzen showed up.
- aurareturn 2y agoIt's true. It's hard to see how Intel can catch up to Apple and AMD in the client and server space respectively. However, I still own a substantial amount of Intel stocks because it will be one of the most valuable company in the world if China uses military action against Taiwan. If not, then I still believe Intel will be successful with their IFS strategy because the world is about to enter an era where compute will never be enough and designers want a second supplier next to TSMC.

- bee_rider 2y agoI’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 2y agoSorry, 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.
- bee_rider 2y agoJust in terms of power consumption they don’t compare badly. Performance, of course, no comparison, haha. Agree that it had tons of problems. But branch prediction has gotten better, compilers have gotten better, etc. Maybe they could be handled now!
- smolder 2y agoAnything salvageable from the architecture likely has been used again by this point.
- bcrl 2y agoThe worst part of the P4 was when it went off into la-la land for 4000 cycles of replay. Did you issue a locked instruction? 4000 cycle penalty. Use rep ; movs? 4000 cycle penalty. Some weird internal condition with a misaligned store? 4000 cycle penalty. One could optimize to improve performance in those cases, but the performance glass jaws on the P4 were all consuming.

- tetrisgm 2y agoSick 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 2y ago5 GHz in off the shelf SKUs was passed years ago.
- tetrisgm 2y agoKey word is reliably. I don't think we're quite at the stage where the average cpu can sustain 5ghz, especially for longer periods of time?
- NikkiA 2y agoMy air (noctua) cooled 7900X sustains 12 cores at 5200MHz reliably, but it's honestly hard to find that much saturation, most tasks can run better with 8 cores sustaining about 5400, or 4 cores sustaining about 5500. With better cooling I'd be surprised if I couldn't sustain 5400 on all 12 cores.
- tetrisgm 2y agoThat CPU came out in Q4 2022 and costs $399 today.

- Gravityloss 2y agoOne 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.
- wutwutwat 2y agoWeirdest 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 2y agoThe 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].

- wutwutwat 2y ago> Core I9 14900KF Breaks World Record, Achieves 9043.92GHz Boom, honest, direct reporting. It’s really not hard to do, it takes more energy to think up the clickbait than to just tell the facts.
