If you disable hyperthreading you have an i5.
If you disable half the cores and hyperthreading you have a highly advanced Pentium D.

So... This isn't actually a world record, it's just a record for a Haswell? Because those are some seriously different things, and I'm certain that a bunch of AMD chips have been taken past 8GHz, and that was a couple of years ago.

It doesn't stop this being cool and all, just that if you're going to call something a world record, it really needs to be the world record for all comparable things. It's like saying that a station wagon set a world speed record, then finding out that it was only for station wagons.

Are you sure? As I understand it, the Pentium D was a true dual core Pentium 4 with hyper threading disabled and the P4 was architecturally quite different from the prior Pentium 3. IIRC Intel scrapped the P4 and went back to the design philosophy of the Pentium 3 when they designed the Core Duo CPUs and their successors.

Yup, that was exactly the first thing I wanted to post when I read the "news."

No point in getting an i7 to overclock if you are going to downgrade it to Pentium-level feature-wise to get there.

I know the point of suicide overclocking is to push a cpu or gpu to the absolute max but when are we going to get to the point where we say the standard is to have the system then run a game or benchmarking tool for an hour and stable before we accept the overclock numbers?

Doesn't mean anything really if you have to gimp the chip to get there. I'm with Starbound, being able to boot into windows and open CPU-Z doesn't mean shit to me, let's see you overclock a chip to 7193.8 without partially disabling it and then run some games/benchies and then I'll be impressed.

not really true. Cache is still bigger per core, still has more instruction sets (dedicated hardware).

Cache differentiates Core cpu's more than anything besides Hyper Threading.

So really, this is about as fast as a 3GHz i7? Doesn't seem worth it, losing 60% of the performance.
Of course if you only care about singlethreaded apps, but how many of those are really that demanding? Everything I'm waiting on is multithreaded (and almost perfectly parallel).

'Course he didn't do it for the performance, I get that. It just seems odd since he's only focusing on one small part of what performance is. Really nails how pervasive the "frequency = performance" is.

That's another problem with focusing on MHz exclusively - a 5GHz AMD CPU is in many ways equivalent to a 3-4GHz Intel CPU (depending on what strengths the application plays to).

Really, this could be considered a "14.4GHz CPU" (7.2GHz on two cores), which makes it a lot less impressive if you take a 3.9GHz i7 which would be a 15.6GHz CPU. Again, I'm a bit biased, because my most demanding applications scale almost linearly with the number of cores (and CPUs and workstations, for that matter).
So yeah, two fast cores, that a stock i7 from a couple years ago could beat in many applications... :p

Either way, wake me up when overclocking world-records translate into world-records in either benchmarks or real-world applications instead of merely large numbers in CPU-Z that cannot be used for any actual work.

There already is a standard. It has to boot into the OS and be able to screenshot a CPU-Z window.

Competitive overclocking is about the competition itself, it has nothing to do with real-world benchmark performance. Take it or leave it as it is. Yes, it is abstracted from the reality of how we use our processors, but then Usain Bolt's sprinting doesn't reflect how most of us use our legs, either.

But Bolt's legs do show a practical application of what the human body is capable of with extensive training and genetic luck-of-the-draw.

"Suicide overclocking" on the other hand is more like bodybuilders who cheat using steroids and end up ripping their muscles because they lacked sufficient conditioning from regular training to keep up with the strain... big muscles that cannot do any more useful work than people with half the muscular mass.

Guys you do realize that dividing a frequency by the amount of cores doesn't mean anything right? 7.2GHz dual core does not mean its a 14.4GHz CPU, there are thing like parallelism and multithreading which don't really allow the CPU to scale linearly like that. The CPU will still balance threads even if there are only fewer than normal, it just means each individual thread will have a larger load.

That is not the point.

The point is that those overclock records are doing nothing more than managing to boot into Windows without crashing. If you ran Prime95 or even real-world applications or game on them, they would likely crash before getting in-game proper... they are not proper overclocks; they are just-barely-working overclocks. They are not usable for anything beyond claiming a world record.

If someone rebuilt the 8086 on 14nm, they would likely be able to run it at over 15GHz... but I doubt anyone would want to use it since it is in-order, takes 3-4 cycles just to load instructions from memory and another 2-5 cycles to actually execute them so it would perform about on par with a modern chip running at 300MHz without any of the newer chips' capabilities.

If you want to run circuits really fast, you have to make individual pipeline stages really simple. Intel tried that with the P4 and failed.

I agree with all the comments about this being a "bogus" record. This is an absolutely useless exercise. I understand there initially is a wow factor involved, but if you cannot run anything stable before the thing implodes how is this worth anyone's time? The real world record should be as many people have said - OC that sucker and run some Prime, etc. Then I will be impressed. This - not so much (really not impressed at all).

Nobody is saying the article advertised a world-record that accomplished anything useful.

What most people including myself are bashing here is is the very concept of overclocking contest where the "world record" does not have to be capable of accomplishing anything useful. The whole point of overclocking is to make programs run faster but these overclocking records cannot run anything useful.

This is a bit like saying your race car's engine runs at world-record 100k RPM... but would self-destruct as soon as you shift it out of parked/neutral because the crankshaft is barely strong enough to handle the engine's own compression and drag forces. Come again when you can show me that 100k RPM in whatever gear you need to put it in to hit at least highway cruising speeds.

The problem with overclocking records as they stand is that overclocking normally aims at making an existing product MORE useful but those world-overclocking-record systems are completely useless since they cannot do anything much beyond managing to boot into Windows some of the time.

That's like being given the land speed record and asking for it to be made into a retail car for your own amusement. There are already places to go and find that, this is for the hot rods, drag cars and other impractical yet impressive machines out there.

At least those souped-up vehicles can actually move from A to B.

Those world-OC records cannot do anything beyond booting Windows, This is like a race car cannot shift out of neutral gear: the engine runs but you cannot leave the starting line.

OC records would be much more meaningful if they had to break speed records at something like compressing a standard 1GB file in 7z max-compression format. This would weed out all the just-barely-stable OCs (those that barely manage to boot into Windows) and give contestants a reason to avoid disabling more features than absolutely necessary. This would also prevent overclockers from sacrificing memory and IO performance for higher CPU clocks since it would ruin their 7z score.

Not a very good analogy. More fitting would be; Make everyone else run with an extra 20 pounds, on his back, to compensate for the disabled hyperthreading and cores. Not very impressive, is it?

IBM's chip was the first to hit the 1 ghz mark. back then they didn't have sufficient cpu coolers and most burnt out fairly fast. i'm sure you could overclock any i7 to 10ghz right now, and they would all burn out fast also.

Getting from A to B requires turning corners in general circumstances, just like having a fast CPU requires it running applications quickly in general circumstances. This is not general circumstances: it is a records book. The fastest plane in the world does not have to be able to carry passengers, the highest clockspeed CPU in the world does not have to be able to play games, the fastest car in the world does not have to turn corners. They ARE pointless, if you ignore the point that this is a game just like thee Olympics, and the guy running in circles practicing sprinting so that he can be the fastest will never have to use that ability to escape bears or any other practical task that those legs and speed were designed to achieve.

The fastest plane still needs to achieve the actual mechanical and aerodynamic work, same goes for land speed records. CPU overclock records on the other hand are barely managing to remain stable sitting idlem which would be like running a drag racer that self-destructs or stalls the moment you open the throttle.

4.7 is plenty. Really you should have an eye on your clocks and try and put as little voltage into your CPU as possible. Don't just mess around with faders as if it's a playing program, put way too much voltage into your CPU and you will blow it out on the spot, but a little over what it can handle (and this differs on a per tray basis i.e my number won't be the same as yours) and your CPU can have it's live stunted from years to days.

Pardon me, 7gb.. . . That's really going some place in a hurry. As a kid, I imagined more refined worlds in the future with feats like digitizing human life into computers like 'Tron' or conjuring up Kelly LeBrock in 'Weird Science'. Robot dolls and mechanized women with human like femininity, now that's perverse. To just make body parts like a foot, only satisfies the footless. Speed. My intuition doesn't just revert me to believe after years of progress, of scientific discoveries and systematic changes, it's only about speed. No, to be living without stipulated boundaries, rules laws or the mayhem of etiquettes. That's what we're striving for. The real mongo pongo is to initiate a bio chemical computation of a real whiskey drinking woman with drive to assault your hormones and unleash the power of Mojo Jimmy who conducts the wave form patterns of life. To create a seamless, oxygen-free, static free, 100% pure serine intervening life form making life as easy and elementary as possible. You know, to promote the joy of simply being stupid & happy forever. Suicide overclocking? No, no such thing. just because we're guys who love to break things, we're going there, because someday, she be there.

Well that is your opinion and is why you probably don't do it yourself.

May I also add that most of the things you probably do for fun are quite pointless if looked at the same way... Gaming for example serves no true purpose other than entertainment, and yet we expect people to respect our hobby, and are offended when they crap all over them for no other reason than their handicapped perceptions. Right now you sound like one of those people.

If the speed limit is 60 miles per hour and you can get 50 miles per gallon at that speed why build a car that can go 200 miles per hour in a straight line at 2 gallons per mile? Because we want to and we can. It's always a who has the title for the fastest competition. BMW releases a car that can go 180 miles per hour, Mercedes-Benz releases a car that goes 190; Intel can hit 7GHz, AMD can hit 8GHz. Are either of those scenarios practical and what you would see in day to day use? People have been doing things just because they can and to say they did for a while.
