AMD finally seems to have put a realistic assessment of its processors, with its claims of the Phenom II X4 having "massive headroom" with its overclocking potential being validated once again, this time by Team Finland, at a CES overclocking event. Team Finland was able to overclock a Phenom II X4 940 processor at its highest stable clock speed of 6.30 GHz using extreme cooling. Earlier attempts to overclock the chip beyond the 6 GHz mark only yielded in test-beds that were able to POST, boot and display the clock speed using CPU-Z. This attempt however, was a benchmark-stable overclocking feat.
The bench consisted of a Phenom II X4 engineering sample, DFI LANParty Dark 790FXB-M2RS, OCZ DDR2-1066 memory, two Radeon HD 4870 X2 graphics cards in CrossfireX and Windows XP. The CPU cooling employed was liquid helium, which dropped the temperature to -242 degrees Celsius. To achieve a clock speed of 6.30 GHz, the processor's vCore was set at 1.84V, its bus speed at 280 MHz and a multiplier of 22.5 was set. The HyperTransport frequency multiplier was set at 8. The Radeon HD 4870 X2 accelerators were set at 800 MHz (core) and 950 MHz (memory). The machine was put through 3DMark05, where it ended with a world-record score of 45,474.

considering i have used a 7750BE, 6400BE, 5000BE, e1200, e4300 and several other chips the e1200 easily ran as good as the AX2's in everything. of course my fav chip to use this far was a phenom 9500+ and there was no comparing that to any dual core
by: mrw1986While the i7 is faster, this doesn't prove it though.
So all this does is prove that i7 is better:

They are using very different gpus and 3dmark05 would be massively cpu limited hitting the overall 3dmark score. What would have been a proper indication is the cpu score on 3dmark05 vs a 3dmark05 i7 cpu score.
i7 is better just because of the QPI. The Phenom has nearly 1/2 the bandwidth (1800-2000MHz HT FSB) if these processors were put on full load. If AMD upgraded the HyperTransport with the future 3.1, which is what many enthusiasts are right now yelling in AMD's ear for, AMD should be fairly close to the performance of the i7 on full load clock-for-clock.
by: chris89You dont have to put tri channel in an i7, it is quite happy taking dual channel.
Yes it will, But not expensive Tri-channel.
by: PCpraiser100that 1800-2000 is double pumped for 3.6-4gb/s

and even at full load you will not max out the QPI or HT on these chips this was easily proven several times when it was turned down and caused NO EFFECT
I really hope we don't go back into the i7 is just better conversation, or I may just stick a red hot poker in my eye. This is well established. i7 is just faster, and a whole bunch more expensive (when comparing good boards to good boards). Let's really try hard to stay on topic here.
Paulieg, the IFB's and ppl who dont care about price will alwase be "i7 is the best, c2q is 2nd best, amd sucks" thats what u see over at Hard for example.

AMD sucks? You should stop over-exaggerating your replies more often.
True that AMD can no longer compete with Intel's arsenal right now, but AMD doesn't really care about the word "competition" anymore, they just care about what the consumers need most, not enthusiasts. Sure, AMD kinda over-hyped us a bit when Phenom came out with nil overclocking, but so did Intel who decides to force people to upgrade their way to CPUs, mobo by mobo, which is insanely inconvenient for new builders who don't wanna keep on building. Sure, Intel rocks most of the time now that they've set the gap, but AMD is still good enough for gaming and multi-tasking as well as not screwing us over with incompatibility issues and overpriced processors with unlocked multipliers :laugh:.

Sure thing, anyway I am pretty excited that Phenom now has insane overclocking capabilities. Especially if it can run 3DMark pretty stable. However if this 125W Phenom can hit that high, does anyone think it can crack 7GHz?
That's a lucky number!
It really shouldn't be considered a 125w model. Considering it only takes 93 watts at 100% load, where as a 9850 takes 135w.
I am just impressed though that they benchmarked over 6Ghz. People can always boot and get a CPU-Z higher than stable benching. And with AMD Overdrive I could easily see 7Ghz CPU-Z verify real quick then tone it back down. My bet is it will happen.

nice score but it must good benches there like super pi
I would personally prefer to see some benches from say PC Mark, AMD has always been strong on floating point calculations and PC Mark is a more "rounded" bench, I actually think the P2 may do well in it. Being a retired overclocker now, i really do wish that all CPU's and motherboards were locked so none of them could overclock, it can get a bit tiresome when people compare stock speed performance and then go off on a "but this one overclocks better than that one blah blah" As I said earlier, from a total platform cost the p2 would simply be excellent performance for the $ from what I have seen and we should all be grateful it;s here, if only to squeeze Intel just a little!
if it was possible, id take one of their opterons (Am2+/AM3) and unlock it to become a BE/FX and see how far i can push it vs the Desktop parts
Totally missed this news here.. Go Finland! :) Hope you all checked the source link, there are some funky helium mist filled pictures.

I'll translate the picture texts just in case if you are interested:
- Copper CPU bowl was first cooled by liquid nitrogen to -190C
- After this the liquid nitrogen was removed and replaced with input hose from liquid helium container
- Bottom of the bowl reached -242 degrees with liquid helium
- Phenom II X4 -processor was working @ 6.3GHz in the tests
- Team Finland from left to right: Sami "macci" Mäkinen, Petri "SF3D" Korhonen, Sampsa Kurri
heheheh, yeah must be super duper stable, they know all this without running the cpu test hahahaah.
seems like a bit of a farce to me, im still not convinced that PII will beat i7 :ohwell:
very nice! glad to see this :toast:
by: kyle2020Ughhh. Of course it won't. Please read my post above. :banghead::banghead:

by: hayder.masterThe WPrime benchmark is the way of the future. ;) Super-Pi is so... "single-core centric." :laugh:

by: mdm-adphThen use Hyper-Pi (multi-threaded SuperPi).

by: btarunrEither that or WPrime, aye. :D
Then use Hyper-Pi (multi-threaded SuperPi).
For total system performance which focuses on CPU speed, memory read and write latence plus HDD access times, the good old Sceincemark is still hard to beat, the downside is that it only uses 2 cores max I think.
