Neben Planet 3DNow! waren auch einige andere Redaktionen nach Austin eingeladen, um einen ersten Blick auf den AMD Phenom II auf 45nm-Basis zu werfen. Die Berichte der Kollegen wollen wir Euch natürlich nicht vorenthalten.


Wer unseren Artikel allerdings noch nicht gelesen hat, sollte sich hier vorab informieren:<ul><li><b>Zum Artikel:</b> <a href="http://www.planet3dnow.de/vbulletin/showthread.php?p=3787136">AMD Phenom II "Deneb" - der erste Kontakt</a></lI></ul>

Will benches net langweilige folien. PFUI. Informationswert gleich null für uns fans. :]
 
da mußt du bis zum 08.01.09 warten;)
 
Wie da keine große Seite dabei ist. Nur "Fan-Seiten" , totale Freak-Pages oder sowas wie Fudo. Komisches Ding.

Hi...

ich finde es etwas bemerkenswert, wenn es einerseits heisst, dass eine "weitreichende" NDA von AMD verhängt wurde, andererseits liest man überall doch schon von ziemlich vielen Details.
Taktraten, Spannungen, etc....
Interessant finde ich, dass anscheinend mit LN2 der 45nm SOI Prozess ähnlich hohe Taktraten erlaubt wie HKMG 45nm....

Der berüchtigte ColdBUG scheint mehr oder weniger Vergangenheit.
Noch interessanter finde ich, die extrem geringen Leckströme, dier dieser Prozess anscheinend bietet...

Wenn ich mal so spekuliere, dann hat die Konkurrenz zwar mit dem dynamischen deaktivieren einzelner Cores im Idle zwar im Teillast einen Stromverbrauchsvorteil - bei Vollast wie BOINC kommt dieser Vorteil aber nicht zum tragen...Bei Vollast und moderatem Takt dürfte der Deneb hervorragende Effizienzwerte bieten....

Grüße!
 
The slowest system—cooled with a heatsink and fan—managed to reach just under 4GHz with a 1.55V core voltage. With liquid cooling, AMD successfully pushed a 45nm Phenom II in another machine just over the 4GHz mark. That required kicking up the CPU voltage to 1.6V, however. For the other two systems, AMD took out the big guns. One was strapped to a phase-change cooler and reached the mid-4GHz range at 1.7V, while the fastest system managed to well over 5GHz using liquid nitrogen (which kept the core temperature down to a chilly -185°C).

und

While the unit demonstrated was @ 3.9GHz, we later had a hands on benching period with the new platform and I was able to quite easily reach this stated 4GHz frequency.

This same platform also exceeded 5GHz on liquid nitrogen cooling. But what was perhaps the coolest (no pun intended) specific of this demonstration was the processor operating and even cold booting at -196 degrees Celsius - that's right, AMD has no cold bugs of any kind, at all for Phenom II!

During this LN2 session the system was demonstrated operating in excess of 5GHz and running 1.95v BIOS set (1.936v CPU-Z read in Windows) and as stated, at the maximum lowest temps available with liquid nitrogen - time to find a liquid helium supplier peeps!

* Air: Around 4GHz is a safe area to target with decent aftermarket cooling & mild voltage increase. When I say "around" that means above and below, so don't gripe at me if your CPU won't hit 4GHz, there is no guarantee with overclocking. Also there aren't exactly huge amounts of CPUs out in the wild yet, so observations are somewhat limited.
* LN2: If you were thinking 5GHz, guess again (and guess higher)... It was like the Energizer Bunny commercials... they just keep going, and going, and going. To say in excess of 5GHz is an understatement, but that's about as detailed as I'm allowed. There was another large leap too between what was "stable" and what you could get a CPU-Z screenshot of, so that shows even more promise in the long term as yields will undoubtedly improve.
* Water & Phase Change: Obviously somewhere between Air & LN2. This is really going to vary based on what you are using and your temps.

While I can't give exact numbers in terms of GHz, I can give you some of the voltages and temps seen while running the Crysis demo. Keep in mind these temps are not anywhere near 100% CPU usage, but they aren't exactly idle either.

* Air: Cooler Master Hyper Z600 - Around 1.5-1.55V / 33C
* Water/Tec: CoolIT Freezone Elite - Around 1.6V / 38C
* Phase Change: VapoChill - 1.7V / Below 0C (software / MB wouldn't report negative numbers)
* LN2: 1.75V (at least during the Crysis demo... *grin*)

3,9GHz @ 1,55Volt...okok, klingt an sich doch recht gut, da 1,35Volt Standard-Spannung ist :)
