No, thats just what they managed to OC it too. Besides, my 3.45 9650 is apparently still faster, so phenon 4ghz < Intel.

The guy in the last picture won the 40 Kg mens weightlifting at the Olympics right??

Great overclock ... but like all LN rigs ... useless in the real world.

Can't see any of us playing crisis on it ... unless you have a PA monitoring the LN feed into the "cauldren of death".

Not only is it slower Clock for Clock as mentioned above, a quick OC is not relevant. What is more important are OC's that are maintainable for long term use that don't fry your computer.

This is the fastest OC Phenom to date. Core 2 Quads beat the Phenom clock for clock and the best is around 6-ish GHz

This guy is using liquid nitrogen. Kinda hard to find don't ya think?

I believe there were some Cedar Mill Cellys that approached 7GHz on LN2.

so a phenom 4ghz = intel ?



Not really a practical comparison - except for the uber-fanatics.

To tell the truth, I'd be happy enough with a 2950 BE at 3.2ghz, or even at 3.0ghz. Realistically, except for a very few things, like benchmarking, bragging rights and an extremely few number of games and sims, anything over 3ghz is pretty much wasted. I'm more interested in having more SB750 mobos on the market.

SuperPi is unfortunately a horrible benchmark to go by. If we go by this then this Phenom @4GHz can't beat a Nehalem @ 2.66GHz (which was 17s BTW) and that just is not a good judge of true CPU performance.

Basically SuperPi does not = true CPU performance.

The fact that it takes liquid nitrogen to reach a clock speed that is surpassed by Intel processors using air-cooling... don't you think that speaks poorly of AMD processors? What? Are they going to run giant ads saying "WE ARE JUST AS FAST AS INTEL" and then have a little disclaimer at the bottom saying "when AMD processors are overclocked and cooled with liquid nitrogen and Intel processors are run at stock speeds" My X2-4400+ was absolutely awesome back in the day... but come on... how is this supposed to impress me?

I think that it is impressive that they got the AMD to 4 GHz. Sure its on LN, but thats not saying a whole lot. And the reason that they are using LN is because the processor has a 140W thermal. I stumbled on a website that listed the new Denebs as pulling 1/2 the power of the 9600, which is really respectable. (Especially when going from 2 MB L3 to 6MB!)
I dont care about the current phenoms. I care about the denebs and shanghai. I think those might hold some serious potential.

This reminds me of a story sometime ago, about a Pentium 4 being pushed to 8Ghz. These High clock speeds are irrelevant for everyday users, but it's interesting to know they have achieved such a clockspeed on the AMD Phenom, which up to now has been considered a terrible overclocker

It does matter when you can take a C2Q and OC it to over 5GHz on LN cooling.

Deneb, we will have to wait and see how much less power it uses cuz well 1/2 the power at the same speeds doesn't seem fully possibly with just a die shrink. I would say 10-15% less IF that power will be used at the same clock speeds as Phenom while boosting performance by 10-15%.

Speedbird, intel stated that the pentium 4 would scale to a clock speed of 10Ghz for normal desktop use (I.E aircooling, the same low-power requirements) But as it turned out even getting to clocks that high didnt show much performance gains over chips clocked at half the speed, which had small gains over the pentium 3's. Those P4's also had to double the clock speed to match AMD64. They could have made 8ghz deployment practical, but it still would have sucked.

No, LN cooling doesn't matter, beyond purposes of overclocking records and synthetic benchmarking records which are largely useless to begin with, they never have, never will. Liquid and phase change cooling overclocks are actually repeatable in real world settings, LN is just "freeze the cpu, jack the voltage up as high as it goes and look at the big numbers before the silicon melts.

Besides the fact that higher temps and voltages change the thermal resistence of electrical pathways you start seeing dimishing returns in performance the higher the clock gets. Actually those things are directly related.

Since they were able to drop dual core power consumption down from 125w to 65w with essentially just a die shrink now down to 45w, and 65nm Amd quads are already available at 65w desktop, 55w/75w server...i'm sure you'd say alot of things. It doesn't make them anymore than a guess based on faulty conclusions and incorrect information.

I have my 9850 at 3.52ghz, with air cooling using a 790fx chipset, there's alot to be said for replacing stock heatsinks on the motherboard and making sure the mosfets are cooled as well as the NB/SB and cpu.

I would say the nehalem isn't shaping up to do to well in gaming performance...but than again, there is actually evidence to back up that statement. There is nothing worse than a clueless intel fanboy trying to pass themself off as unbiased.

Reply to cpuTweaker

I personally don't expect AMD to blast Intel NOW, but Its good to hear about the die shrink and the results in power consumption. They are doing something. They have to keep improving, while keeping reasonable prices on their CPUs.
