AMD Breaks Overclocking Record With Bulldozer
MojoKid writes "AMD recently held a press event at their Austin headquarters, offering hands on time with the company's upcoming Bulldozer-based FX-line of processors. Many of the details disclosed are still under NDA embargo, but AMD is allowing a sneak peek today to go along with a claimed Guinness World Record announcement. A team of overclocking enthusiasts and AMD engineers had a sampling of early AMD FX processors running at around 5GHz with high-end air and water-cooling, in the 6GHz range with phase-change cooling, and well over 8GHz on liquid-nitrogen and liquid-helium setups. Voltages of over 1.9v were used as well for some of the more extreme tests. The team had access to dozens of early FX processors and methodically worked through a batch of chips until ultimately hitting a peak of 8.429GHz using liquid-helium, breaking the previous world record of 8.309GHz for modern processor frequency." Update: 09/13 13:54 GMT by T : Adds user Vigile: PC Perspective was there and took some photos and video of the event.
I bet these liquid-helium cooling kits do not come with a warranty from New Egg!
I only look human.
My mother is a halfling and my dad is an ogre, so that makes me an Ogreling
I also attended the event, and wrote up a more detailed account of the demonstration and word record result for the overclocking audience: http://www.overclockers.com/amd-fx-bulldozer-breaks-cpu-frequency-world-record/

Do not look at laser with remaining good eye.
To almost a tenth of the price? I'll take it. I don't need the fastest. Just fast enough for my needs.
Give away the processor, and sell the liquid helium. The gillette model all over again.
Then why did you post instead of just modding him up?
You need mod points for that stunt.
486 (and it was only enabled for the DX) - the 386 series still needed a separate FPU. The difference between the 386 SX and DX was the size of the data bus.
Their solution won a Grammy, but the public won't be able to make full use of it until 2078.
Ahh no.
The FPU was integrated in the 486DX you could get a cheap 486SX that didn't have an FPU because heck who needed one except for CAD users.

For the history of the x87 family.
10 years? Naw I give it five max. Once APUs can play games at 1080p with all the eye candy almost no one will buy a separate GPU. They day that they can driver two 1080p displays at that level it will be all over.

Liquid nitrogen vaporizes, forming a gaseous layer which protects exposed skin. You *can* put it in your mouth, and look like you are breathing steam, but you can't swallow it (as the gaseous layer gets forced aside causing you frostbite when the liquid presses against your internal linings, and it rapidly expands in your stomach, which makes you expand too, possibly fatally). See http://darwinawards.com/personal/personal2000-25.html
You can wash your face with it, but your hair / body hair *can* perforate the gaseous layer, resulting in localized frostbite, and hair loss. If you jumped into a pool of it, it would kill you, but *just don't do that*. Geez.
It's like the difference between a hot coal, and a pot of hot coffee. Drop the hot coal on your lap, and it will vaporize the top layer of your clothes, causing no real damage (and creating lots of comic relief for observers), unless you leave it there for a significant period of time. Drop a pot of boiling coffee on your lap, and you may no longer be able to reproduce. But people just assume that the hot coal is more dangerous, because it is hotter.

"My CPU overheated while I watched porn. Wanted to add some nitrogen and that's how I lost my John Thomas"
No. Liquid nitrogen is easy to use safely. It's common in undergrad-level labs, can be reasonably easily purchased (like dry ice) by just about anyone, and only requires minor safety procedures. Liquid helium is more dangerous, but is common in graduate-level labs and is not particularly hard to work with if you know what you're doing. It is really quite expensive, though, and a complete waste to use for cooling something that's producing ~100W of heat, since it doesn't have a very high heat capacity.
It's probably easier to injure yourself with home power tools than with liquid helium. It's just that fewer people have experience properly handling the latter.
It's not that dangerous - the system operates just like a regular refrigerator. The cooling system is filled with helium gas at room-temperature. A compressor is used to compress the gas to high pressure - this causes heat to be emitted. As the pressure decreases, the helium liquefies before reaching the processor where it then heats up again and becomes gas again and the cycle is repeated.
It's not like some dude is standing on a wheeled office chair above the PC, with a flask of liquid helium in one hand, a funnel and some rubber tubing in the other trying to keep the end of the tube aligned with top of the CPU.

I picked up this trick in an undergrad lab from a professor, though he didn't quote it by name. Pour LN2 out of the container onto the palm of your hand - it steams and falls out onto the floor. The key is to position your palm so that nothing collects there - everything rolls off - and not to do it for too long, because even though there is a vapor barrier that, it is chilling your hand.
It looks pretty neat though, and has a lot of wow factor to someone who doesn't understand that it can easily be done safely.
The living have better things to do than to continue hating the dead.
Okay, your post is a little bit of flamebait, but I'll bite.
I can purchase the A-3850 for about $40 less than the i5-2400. Certainly, the i5 will trounce the A-3850 up to the point where you want to process graphics. Once you start to process graphics, you can't really compare the Intel HD 3000 to the on-die Radeon 6550. If I want comparable graphics, I have to purchase $150 graphics card. I can also purchase the ASUS FM1-Pro motherboard for about $50 less than a similar ASUS board for the i5 (with comparable features). After this setup, my A-3850 will probably peak (with full graphics acceleration) at about 150 watts, while the Intel would likely run at 250 watts or more.
Taking into account power consumption, the AMD setup won't be 10% over 3 years, but it might be 30% the cost of the Intel setup. Unless I'm doing a massive amount of heavy lifting (like constantly transcoding HD video) then the Intel might be worth while. But, my PC is idle 95% of the time with only a few spikes of CPU usage.
Don't you think those of us working on these chips haven't thought of that? This problem was recognized back in the 1940s , for goodness sake. Quote:
There's a limit to how fast even the processor's own registers can go, such that some designs include "local register files" to individual ALUs, because the main processor registers are too slow.
Program Intellivision!
But you see, here is the thing about that. Unless you are one of the rare (although admittedly more of them exist here than in most places) people that are slamming the living hell out of your CPU and need to scrape up every single last flop you can CPUs are long past good enough for pretty much any task the common man can think up.
I was a lifelong Intel+Nvidia man until bumpgate and the massive bribery and compiler rigging came out, then for the first time since the K6 I built an AMD machine for myself, and you know what? Frankly even without going for the top o' the line chips its insanely overpowered. Video editing/transcoding, DVD ripping, gaming, you name it my 925 quad takes it like a champ and keeps right on coming and the whole thing, with 3Tb of HDDs, 8Gb of RAM, dual burners, HD4850, and Win 7 HP X64, cost me barely $700 before MIR, around $640 after. And that was before the prices dropped, now you can probably knock a good $150 or more off that easily.
I am a hell of a lot harder on a machine than the average folks which come to my shop so for them the bang for the buck is even more insane. When you can hand them a triple or quad for $500 or less and still make a decent profit? That is just nuts! But I bet if you were to check your CPU usage long term a good 80%+ of the time your CPU is twiddling its thumbs waiting for you to find some work for it to do. the only ones I've found that might need the extra 20-30% speed boost going Intel might give you and are willing to pay the 200% higher markup for that speed are guys doing a shitload of compiling. like I said there are more of those type here, but for everyone else? You can get an insanely overpowered and loaded to the brim machine for dirt cheap by going AMD. The bang for the buck is so far in the AMD camp now it isn't even funny and that is before you count the kick ass GPUs compared to the shite on a crusty roll that Intel calls a GPU.
So if you are not one of those 4% that slam their CPUs and push them to the absolute limit why would you spend the extra money on Intel? Like I said monster quads for less than $500 and you can even buy quad laptops for that price if being mobile is your thing. Its just nuts!
ACs don't waste your time replying, your posts are never seen by me.
Wow it is amazing some times what people read.
"Yeah, because no-one will find a use for all the extra power that a discrete GPU would give you."
I never said that at all. I said almost no one will buy a separate GPU. Notice that the word "almost" which means that some people still will.
This issue here are economies of scale. Even today the majority of systems probably use integrated graphics. Most systems sold today are notebooks and most notebooks use IG. Throw in all the corporate desktops, school machines, and the average home users and I am willing to bet that most users already are using IG today.
Now as you said most modern games are console ports. Do you see that changing? I sure don't anytime soon because that is where the money is right now. The game makers will all jump for joy once the average desktop and notebook can do good HD graphics. The can then have a good sized market on the PC to target.
The end result will be as IG gets better and better the market for desecrate GPUs will get smaller and smaller. As the market gets smaller and smaller the costs will go up faster and faster for less and less gain. You will have the same situation that you have with audio today where a few people spend the money for a high end sound card but most people are very happy with the sound buit into the motherboard.

Passmark is measuring real systems, mainly as assembled and delivered by companies like Dell, to Joe Public who then runs PassMark.
...for benchmarks of the i7-2600K I am listening to 4257 sources (869 benchmarks of this CPU in the past 30 days alone.)
...for benchmarks of the i5-2500K I am listening to 2882 sources.
...for benchmarks of the i5-2400 I am listening to 692 sources.
.. or single threaded integer performance.. or multi-threaded simd.. etc...
You can make excuses all you want for why you would rather believe the obviously less realistic benchmarks of the tech sites, but they are still just excuses.
While you think I need to get over myself.. you need to get over the obvious flaws in the "information" delivery framework that you have been listening to.
You claim that I am listening to one source, when in fact...
This is crowd benchmarking. I am not listening to one source. I am listening to a crowd of sources.
With their software I can even narrow things down to specific motherboards, or specific memory chips. Compare memory bandwidth of various setups (actual results of many people)
You are in the stone age.
"His name was James Damore."
>>No it isn't. It just seems natural to you since you're used to it. To everybody not still wedded to archaic units, meters are perfectly natural and usable.
Natural in the scientific sense, not the psychological sense. In other words, Kelvin are a better unit for temperature than Celsius, since you have to convert Celsius to Kelvin in order to do any thermodynamic calculations. A nano-lightsecond (aka a foot) makes a lot more sense to work with than the rather arbitrary meter unit. Call it a nls.
In fact, this thread shows exactly why that is true. If people used feet/nano-lightseconds instead of meters, the OP would have been able to much more easily calculate how far travels in a 1GHz processor (i.e. one foot) or a 8Ghz processor (1/8th of a foot or .125nls) and how that compares to the 17mm die size. Ah, see, but wait - we're using the non-natural mm measurement, so we have to convert to nls! 17mm = 0.0558nls. So we're still below the theoretical maximum by about a factor of two, though path length issues are obviously going to set a hard limit before that.
