the coldbug with phenom doesn't seem to be related to HTT reference clock speeds anymore. and chips that boot under cold at stock settings will overclock under that cold. this means some major changes happened along the road, but we haven't kept track, as all the cold "fun" is at intel's feet.

ARGH!!! Thanks for the post, but I hate that I have to wait till Jan to get one :(

Still.. can't wait ti see what AMD does w/ this new chip :)

I wish they would release the freaking X2 7000 line of chips already as AMD has been hurting real bad by not having a dual core solution that can match the core2 crap intel offers for an arm and a leg. Hopefully the prices on these new AM2+ chips will not be over $250.

That be hilarious.

Who cares as long as they perform clock for clock equally or are close enough that OCing you'd actually see a difference not just trying to make up for lack of performance.

Yeah I agree they need some nice dual cores out too. Phenom/Agena wasn't enough of a boost to warrant a new X2 I don't think, but this looks to be much more promising so a 45nm X2 would be nice.

The PFET performance improvement is more dramatic with drive current now up to 660 µA/µm compared with 510 µA/µm on 65-nm transistors. Again, this increased output current is the result of optimized compressive strain for the p-channel device. The new design of the PFET moves the embedded silicon-germanium source/drain regions closer to the channel to maximize the transfer of stress, thereby increasing hole mobility. Although shorter gate lengths are not driving the improvements, it is a reduction in dimensions that allows increased channel stress to provide the performance scaling. AMD 45-nm PFET design reduces the space from embedded silicon-germanium to the channel edge by half.

The transistor drive current for AMD's 45-nm devices is much lower than that of the Intel HKMG transistors. But power consumption is quickly becoming a high priority for server chips. AMD's transistors exhibit very low channel leakage. Our transistor benchmarks indicates that leakage current is less than one-third of the value measured on AMD's 65-nm process. It's also significantly lower than the Intel 45-nm HKMG process. In fact the Ion/Ioff ratio for AMD's PFET is nearly 10 times better than that for the Intel PFET.

PURE SPECULATION WARNING: If I read the above right, then high-k metal gates in the FX models will provide even more overclocking potential. Since i7 has metal gates, wouldn't the above chip design plus metal gates allow FX to leapfrog i7 overclocking performance. I mean if you can get 4.0+ without metal gates on a Phenom II then the chip should turbocharge forward with the FX design that has metal gates..... :up:

You sure? I have been seeing a lot of screenshots of SuperPi and Prime95 stable 3.4GHz 9950s since the SB750 came out.

Where the hell did you get this High-K/metal-gates on the FX story from? All I've seen is that AMD had/has plans to at High-K/metal-gates to their 45 nm. process in the second half of 2009, but the recent road-maps did not have this 'revision' on them anymore and that they would introduce it at their 32 nm. process node. That's why I would like to have more concrete information on this, as it all seems to be (or is) rumors.

Hmmm, now we've read that though... high/k and metal gates do not guarantee improvement. I dont know really, but what if their 'trick' isnt able to use with high/k and metal gates, then they're actually worse. That's for power consumption and leakage though, I dont know if high/k and metal gates would improve clocks.

I will upgrade CPU when the dust and price settle in Feb, March:)

That looks pretty marketingish to me. I'll be surprised if I go from 200fps in Quake 4 to 600fps due to a CPU upgrade.

It's a platform upgrade, not just cpu

i think i read somewhere that dragon is amd chipset/4800 series gpu/phenom 2 so for many people its just a cpu upgrade

at least they started at 0% and not 100% lol

spyder platform 100%. is that with four 3870's, four 4870's,or two 4870's ( who knows lol)

Not really. The spider platform already is comprised of the 790FX, Radeon 3k/4k graphics, and a Phenom. For someone to go from Spider to Dragon just means a CPU swap.

No. Spider is 790FX/600, Phenom and Radeon 3xxx.
Dragon is 790FX(GX)/750, Phenom II and Radeon 4xxx.

There is some slide about this.

So then my system is post-Spider and has no fancy label. I'm still one upgrade away from being a Dragon.

Perhaps it could be called a Dragder or a Spigon.
