New AMD Turion 64 dual-core with 1.075V at full clock

New AMD Mobile Dual Core Spotted

[...] this chip runs at a maximum clock of 1.8GHz and idles at 800MHz; much like current Turion 64 chips. What is most interesting from this is the voltage that this chip is able to use at full clock: a mere 1.075V! Current 90nm Turion 64 processors run at 1.45V default, that is an amazing drop!

[...] When at 800MHz, the processor operates at 0.9V. While we have seen no power consumption figures, it is fair to assume from this that Turion will be very power efficient at idle and maximum clock.

Laptop Logic had to remove the exclusive screenshot, so it's no longer there. However, the same screenshot was posted on matbe:

Very impressive... if true.

Early leaks do tend to talk up products to be better than they actually are so let's hope this one is correct.

So the TDP on this would be in the 35 watt range? It would be similar to the 3800 runing at 1.1v that some people are doing now right?

FWIW, I was able to run my old Turion64 MT-34 (1.8GHz, 1MB) at 1.1V completely stable, 1.075V pretty stable (would get random crashes every few days). 1.075V doesn't seem too crazy for a dual-core 90nm Turion64.

Were you able to cool it passively at that voltage or was it still putting out too much heat?

IIRC he was running it passive with a Scythe NCU-2000 with a Seasonic S12 fan being the only exhaust.

Yes, I actually have a thread in the gallery forum about it if you're interested.

With a Scythe NCU-2005 and Seasonic S12-300 @ 700-800RPM, CPU load was around 39*C. I later tried an internal DC-DC converter instead of the Seasonic and tried running the computer completely passive with no fans. IIRC CPU load only climbed to like 45-50*C or so. What's funny (I think, at least) is that heat from other components, such as the northbridge and voltage regulators/MOSFETs, worried me much more than the CPU.

Maybe even lower, since there are Opteron 170's running at 1.3 V (standard version, not EE or HE) and got a 35 W TDP.

Also, it is likely that these Turion dualcore CPUs are rev F based. If so, they will, as I understand it, be manufactured on the new SiGe process. Not only should that bring down power further, but rev F cores are supposedly (process aside) more power optimized than their predecessors.

Nothing's for certain, but we'll know soon enough.

Really?! Could you post a link?

Thanks,

I was wrong, it was a 175 (2.2 GHz) running at 1.35 V and hava a TDP = 35 W.

I'd love to have one of those chips! I wonder if they are all like that or if it's only some.

Only some of them have that low TDP, most of them are like 60 W or so.

Grrrr. Why can't they make things more simple so that every range of chips has the same characteristics and you don't have to hunt around for the chip you want. :evil:

Well I guess you'll like the F revision then.
