AMD Piledriver rumours ... and expert conjecture

[Reynod]

We have had several requests for a sticky on AMD's yet to be released Piledriver architecture ... so here it is.

I want to make a few things clear though.

Post a question relevant to the topic, or information about the topic, or it will be deleted.

Post any negative personal comments about another user ... and they will be deleted.

Post flame baiting comments about the blue, red and green team and they will be deleted.

Enjoy ...

is tht the new cpu tht amd releasing in tht link?

 

[skitz9417]

i cant wait for the cpu to come out because i have a amd phemon x4 840 i hope the new cpu is better

 

[skitz9417]

i migh or i might just get the new amd cpu

 

[skitz9417]

does any know when it comes out

 

[king smp]

does any know when it comes out

just buy this
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103924

at $115 with free shipping

it will easily OC over 4ghz
probably get 4.2ghz with good cooling
nothing in the Piledriver lineup at $115 will even come close to its performance

or i might just oc my cpu

Those are getting harder and harder to find. PD line up isn't out yet, one of their three module units might be up for the task, depending on workload.

not at the $115 price point

I am not a gambling man but I would bet that at the $120 USD price point nothing in the PD lineup will beat a 4ghz PHII Deneb

of course in other countries this might not be true due to availability of Phenom x 4

@palladin- do you have a link to Kstat10(?) download? is that freeware?
I did a quick Google search and had no luck

 

[jimmysmitty]

Look at what i've found.

Yet you can't buy either stand alone. I have been watching for the FM2 mobos for my work but we haven't seen any. On top of that I read a rumor that FM2 may not support FM1 CPUs, but I don't think that is true as its the same as moving from Phenom to FX.

I wonder there are low yilds and that is causing AMD to delay the CPU launch for consumers and rather they get as many into OEM hands as possible.....

Three modules = 6 cores. BD's were about 0.75 the performance per core.

PD has had several improvements in both IPC and power usage (results in higher clocks).

So an OC'd 3 module PD could in theory beat an OC'd 975BE. As far as I'm concerned 120 and 115 are the same price points, 4.3% is not enough to create a separate bracket. Even 130 is pushing it a bit, though 150 is clearing in a different segment.

Yes it's freeware as is AMD PSCheck

I highly doubt that they will release any PD under lets say a $150 price point that will compete with a Deneb at 4ghz
Do you think that they are going to release a three module 6 "core" under $150 USD?
look at the BD prices at launch
even now how much is a six core BD?
the under $150 price point is a quad core price point from what I know
I could be wrong.......

Thank you very much for the link
Much appreciated

That's why I said in theory. I don't know what they'll release, and $115 for a 975BE is amazing, while supplies last.

And remember, you still have people going around talking like the i3 is the greatest thing since sliced bread, and it's only two cores. I'm thinking they priced the 975's like that to empty out the supply channels prior to PD's launch.

the latter wouldn't suprise me as trinity is more geared towards OEM usage. Not a whole lot of need in it for a system builder except small form factor or htpc.

 

[-Fran-]

You're thinking about upgrades alone in your example.

You have to think about upgrade path (if PD delivers) or a good P/P ratio of the CPU.

Like it or not, the 975BE, if it's indeed at that price, is so hard to beat... Not an upgrade, but one hell of a capable 4 core CPU for so little money.

Cheers!

fro skitz9417 who has a Athlon 840 then 975BE would be a pretty good upgrade if Newegg is available to him

me personally the 2500K at $169 at microcenter is too good to pass up
hate to say it but AMD is lacking in upgrade ability or new build potential right now
Hopefully by Excavator that will change

 

[skitz9417]

nah i might just keep it

 

[king smp]

thinking about it
OC the 840 and save up for a Sandybridge CPU and Mobo
I love AMD but Intel is just the way to go right now

just like back in the Athlon XP and Pentium 4 days I recommended AMD as the better choice
and the Athlon64 x 2 vs Pentium D it was the Athlon64 that ruled

ahh the good old days

 

[skitz9417]

yeah i know i can oc my cpu and i dont realy like intel tht much because they overprice there stuff

 

[skitz9417]

nah i will keep the amd cpu for now untill it breaks

 

[skitz9417]

all well when i upgrade in a year or so i will get a better system

Thanx for the link, i miss these articles ever since my IEEE subscription expired

Btw looks like my predictions were correct

What’s more, although a resonant clock doesn’t have to be run directly at the resonant frequency of the LC circuit, its efficiency as an energy recycler goes down when the clock is run significantly faster or slower.

“Driving far from resonant frequency won’t save power, and at some point [the circuit] won’t work at all,” says Phillip Restle, a member of the research staff at the IBM Thomas J. Watson Research Center in Yorktown Heights, N.Y. Cyclos has inserted a switch that allows the AMD chip to turn the resonant part of the clock on and off. But Restle, who performed some of the earliest work on resonant clocks in microprocessors, says the switch isn’t a perfect fix because it adds to the power a chip consumes.


I had talked about this here before, but its a bit messy read 😀

Another fact is that PD's 8 core die could possibly end up much larger than 315mm2, maybe that explains the rumours of a native 3 module die

AMD’s Piledriver CPU design—which forms the heart of the company’s new Trinity chips—uses 92 of these 100-micrometer-wide inductors, spread out over each dual-core processor module.

100 um wide is quite a bit of space there, not to mention that the engineers had to re-design the layout all over again to incorporate the inductors within the module

Wonder why Cyclos and AMD don't use inductor tuning to 2 or maybe 3 clock frequencies, instead of just the nominal base frequency? Seems to me that all they would need to do is to use are switched taps along the length of each inductor to effectively change the inductance value to whatever the current clock frequency is set at.

Of course, if somebody wants to oc their CPU, then the switches could be set to zero inductance, since otherwise the inductor might limit the max oc frequency..

That SKU is showing up at several stores now and in stock.
Trinity desktop has arrived.

I wouldn't mind a little help on the market. If NYSE: (AMD) goes a little more south, I may consider. That is if they offer an alternative in their marketing division, or if this CEO can get this whole circus act together. Other than that, it is fun to watch what happens.

IIRC AMD stock went as far south as a buck sixty-three a few years back.

I would wait for their Q2 conference call next Thursday and see what their prognosis is for the current quarter and EOY.
