AMD Overclocks New Phenom II X4 To 7 GHz

CWmike writes "Advanced Micro Devices on Thursday introduced the latest member of its Phenom II X4 family of high-performance quad-core CPUs, which the No. 2 chip maker said it had run as fast as 7 GHz in extreme overclocking tests. Out of the box, the new X4 955 Black Edition, which is aimed at gamers and hobbyists, runs at 3.2 GHz, giving it similar performance to Intel's fastest desktop chips at lower cost, AMD says. The company was able to more than double the CPU's speed during its tests using extreme cooling technology that is not safe at home, said Brent Barry, an AMD product manager. The Web site Ripping.org notes that hobbyists with early access to the X4 955 chip have been able to clock it at up to 6.7 GHz. AMD said the chip was safe with fan cooling at up to 3.8 GHz."

    AMD has been going belly up for so long now it was easy to write them off for dead. Yet, I'm tempted to pick up their stock. Has to do better than my NBFAQ.

    I think there's still some brand loyalty in Opteron - I love mine and I still think an Opteron will be my next pick of CPU.

    And, the newest go around of Ubuntu Linux has some new drivers for ATI cards that should improve those matters.

    A 7ghz chip is a very healthy prize for AMD. I wouldn't expect them to advertise the power usage on such a thing, but hey, its engineerings, you can't have everything at once.

    I like AMD a lot, and I just hope they succeed. I know that Nehalem from Intel is a strong series of parts, and AMD has a lot of work to do, but the capital costs are so high in chipmaking that it is doubtful we would see another competitor to Intel emerge in a generation if AMD goes out.

      I'd have to say that Intel would be in for a bunch of monopoly lawsuits if AMD were to ever go belly up. It's really in there best interests to maintain competition.

      That's really not true. Intel already maintains a monopoly-sized market share on CPUs, and they've been caught abusing it already (the intel compiler disables a lot of optimizations if code built on it doesn't detect an intel genuine cpu, for example.) It's still certainly in the best interest of the market, especially with child-company ATI being the only competitor to nVidia as well.

      It's usually more honest. Despite what their release schedule says, the CPU producers don't get even increases in speed of 100MHz. New architectures often makes for big bumps, but if they maxed it immediately they could only sell the big bump once and they don't want that. Sometimes they got headroom, sometimes they're pushing the last MHz out of the chip to keep a steady release of slightly faster processors for a healthy profit and steady cash stream. These tests push the chips to their real maximum, making it very tough to throw up a marketing smokescreen. If your chip isn't overclocking well or at all, you're in deep shit. This is basicly just showing off that the architecture is good and got room to grow, nothing more.

  8. How little progress we are making by jmorris42 · · Score: 4, Interesting

    To me the takeaway is just how little progress chipmakers are making.

    Compare to the 1990s. x86 processors started the decade with the 80486 @ 33MHz and ended with the Athlon @ 1GHz mark and was doing more per clock for even more improvement than pure clock ratings would indicate.. Now in the decade we are about to close out we have managed to push that to around 3.5GHz and by the end of '10 we might hit 4GHz and eight cores (for those willing to spend serious coin) but work per clock doesn't seem to have improved at all and if anything have even slid back a bit.

    RAM improvement have slowed down as well, probably because of Windows inability to get large deployment of 64bit editions limiting demand. The 1990s saw average ram go from 1-4MB to 64-128MB. It has only been recently that 2GB sticks went from exotic server stuff to mainstream.

    Speed also isn't getting faster as fast as capacity is growing. Compare how many seconds it would take a 1990 vintage 486 to write to every memory location vs a modern machine. Same goes for disk access. Hibernation on a modern laptop is pretty much a dead issue since the time to write the whole memory load to disc is unworkable.

      Are you serious? CPUs are doing a lot more per clock than they did in the past. In case you haven't noticed the sort of invisible 4ghz wall that we've been staring up at for the past 4 or 5 years, clock speeds actually have stayed pretty constant but raw performance as measured by benchmarks and such has been improving drastically - look at Core i7 benchmarks vs Core 2 Duo, or Phenom II vs Phenom vs Athlon X2. Really though, most people don't need more processing power than what a 2ghz dual core provides, if that, so it seems like things aren't improving, but they really have been making significant strides each year.

      I do agree on the hibernation bit though; it takes forever for my laptop's 3gigs to get written to disk. Now I just resort to sleep mode in Vista, which actually works, so it's not too big of an issue.

    ... - for cooling or anything else - be sure to install an oxygen level alarm.

    A nitrogen leak will dilute the oxygen content of the air to the point that you'll pass out - then die - without noticing what is happening.

    Nitrogen is the bulk of normal air so it has no smell. Your breathing is controlled by the CO2 level, not the oxygen content, so you don't notice it when both are being diluted (and the dilution of the CO2 slows your breathing, exacerbating the problem with the oxygen level.)

    This made evolutionary sense because the O2 and CO2 level are normally related - CO2 goes up as oxygen is consumed - and the CO2 level starts from a low baseline and affects pH, making it FAR easier to detect. But it doesn't work very well when people start taking the atmosphere apart into its components and remixing them differently.

      I'm pretty sure your body reacts to the lack of oxygen, not the excess of carbon dioxide.

      You are in fact pretty wrong. The body uses what we control engineers call "inferential control", i.e. watches a certain variable (carbon dioxide) rather than another (oxygen); I am not sure of the advantages, but may have to do with ease of measurement, response time, or simple evolutionary randomness. See the Wikipedia article on hyperventilation.

      In normal conditions this works all right, since when there is little oxygen there is also a lot of carbon dioxide; in conditions for which we did not evolve, like a 100% nitrogen atmosphere, the strategy fails.

      This phenomenon has a number of implications: if you hyperventilate before swimming underwater, you do not feel as much the need for oxygen because of the reduced carbon dioxide in your blood, but you still have it just like before: that's how free-divers used to die, not noticing they were lacking oxygen and passing out under water.

      Also, I work at a research institute, and at my first course in laboratory safety I was told loud and clear that nitrogen is the main laboratory killer, because everyone assumes it is harmless, while in fact it can easily kill without any warning. Every lab using liquid nitrogen has big yellow signs with "asphyxiation danger" written on them.

    Look up the second law of thermodynamics.

    Power goes in on the "work" side of the Carnot Cycle and comes out on the "heat" side. You can salvage a small percentage by running the heat through a heat engine on the way to the heat sink - more if you let the chip get hotter. But not a lot.

    Further, the current technology can't stand being allowed to heat up - and its power consumption per unit of computation goes UP when it gets hotter. So even if you COULD put a bottleneck in the cooling (where you're normally spending more power to pump the heat away faster) to try to salvage some of the energy, you'll be running at a net loss.

    Now if somebody wants to use ceramic, high temperature metal alloys, and low work-function oxides to build integrated circuits based on vacuum-tube technology they might be able to get away with it. But electrons tend to be even larger and fuzzier in vacuum than in condensed matter so you might not be able to get your scale down to that of even current integrated circuits, limiting your speed due to signal propagation time.

    That solves to 4.282 cm. That's 1.6 in for people who don't speak metric. In the time that the processor does a single clock cycle, light in a vacuum can only go 4.282 cm. Electrons on a circuit can't propagate a voltage any further/faster than that.
