AMD demos 45nm at Cebit.

[freeloader]

A dual-core flavour with 3MB of L3 would be a decent part.

How about the full 6mb L3 on a dual core. I'm greedy.

Better yet,how about a Montreal flavor of Shanghai with 1MB of L2 per core with 6 MB of L3 in H1 2009 ?

[Ub3r-L33ch]

How about one that is actually as fast or faster than it's equivalent Intel processor?

Haha good one. Not gonna happen this generation.

PD: Stop posting damn bananas

[Marvin_The_Martian]

Wombat it would make those pic a whole lot more usefull if they included a result

[spicypixel]

1.6+volts?!?
Either its misreported or I just cried a little.

[w0mbat]

@Marvin_The_Martian: The result was that it didnt crash and properly finished the task

@spicypixel: CPU-Z cant read the vcore yet.

[spicypixel]

Ok mind at rest a bit now. I'd probably pay an arm and a leg for a dual Phenom FX 45nm PC right now.

That's would be like trying to go faster than the speed of light for AMD

[Carfax]

I wonder how fast this will be compared to Barcelona?

No more than 10% I'd wager.

[Marvin_The_Martian]

Wombat do you know the speed the system was running at ( core's and nb? ).

[whocaresbg]

Up to 30% according to Fudzilla and other chinese sources .

[Nedjo]

The L3 array is in the NB clock domain, so I don't expect to be in sync with the cores in this 45nm spin off. And above this, K10 has to maintain a specific (async) clock rate for the NB so to avoid weird DDR2 speeds, as it was the case in K8 architecture.

DDR2 clocks speed isn't reason for async speed of L3 in comparison to the cores.

As you aware K10 can independently clock all four cores, but since they must continue to communicate despite different clocks, clock of L3 must stay unchanged…

It would be excellent if L3 would run in sync with cores, but 'cos of thermal budget you must make tradeoff there, and it's proven that gain from core clocking is always bigger then from L3 clocking.

[Extelleron]

From what has been reported, 10-20% on average.

Barcelona -> Shanghai is a bigger move than Conroe -> Penryn. Shanghai has 3X the L3 cache in addition to some core improvements.

Hopefully Shanghai will do what Barcelona was supposed to and run the NB/L3at a HIGHER frequency than the CPU. That alone could improve performance by up to 5-10%.
So in theory Shanghai should be slightly faster than Penryn clock-for-clock but it will get demolished by Nehalem.

Well, let's say it's one of the reasons, or more exactly -- a very intentional subsequent effect.

[ubuntu83]

but Nehalem will need a newer socket because of it's larger size.

I highly doubt that CSI in Nehalem will bring anything to the table -compared to Penryn- when desktop is in question.I think that Penryn's high freq. FSB will NOT be slower than CSI I/O we will see in Nehalem,at least in desktops.Also HyperThreading could potentially speed it up a bit in multithreading apps,but still needs to be seen by how much.

Here we go again with flame war in sight…

Can't we avoid it this time and concentrate to the fact that AMD promised rampup of 45nm production in H1, and delivered! We're promised 45nm CPU's for sales in H2, and looks like AMD will deliver… in contrast to all those Intel fanboys who did screaming around that it's highly unlikely that AMD will deliver 45nm parts in 2009!

informal please don't... if you understand me...

[fellix_bg]

CSI (as HTT) is primary intended to improve multi-socket scaling over the stagnant FSB-based topology.

I think you're getting the wrong idea from my post. I'm not an Intel fanboy and I currently own an AM2 X2 system. I'm glad AMD is on track with 45nm and I hope we will really be able to buy one of these at newegg within the Q3timeframe.

I don't think anyone seriously thought AMD wouldn't deliver 45nm in 2009; they doubted the delivery of 45nm in Q3 2008. You can't really blame them as AMD didn't really execute well in 2007 with the exception of RV670 actually being released earlier than expected.

As Fudzilla stated a few days ago... Shanghai will be smaller and cheaper than Nehalem, but it will be slower and that is a given at this point. If AMD is able to hit the right frequencies and position tri-core at a good price and undercut the quad-core Nehalems with quad-core Shanghai, then I think they will be sucessful.

Of course this depends on how much faster Nehalem is clock-for-clock, but I would assume it will demolish Penryn & Shanghai in multi-threaded apps because of SMT and the ability to execute 8 threads on a Quad-core CPU. And I think we should expect Nehalem to be much faster... AMD is still bringing a (now) 5-year old architecture to the table to compete against two NEW architectures from Intel.

Any idea of clock speeds?

[Marvin_The_Martian]

More intel discussion in this Amd thread?

Idk who's not getting it Extelleron, but a bird just told me the name starts with an E.

I'm glad AMD is delivering, just as you are Nedjo. Now they need to send me a few test samples offcourse :d

And I really want to know both the speed they demo'd at and the initial launch speeds for the 45nm process.

Edit: Metro get in line I asked first (#37)

[[XC] gomeler]

This is exciting. Deep down a small part of me wants to play with a Phenom and K10.5 might give me the option to do it without the performance part of me disowning the rest of me.

...so it means end of the summer we will see some power point presentation without any real benches... blah blah blah

It is a very good thing my name isn't in a darker color or you'd have a temporary vacation. Rawr
