AMD Zambezi news, info, fans !

what's your opinion on the fabric like heterogeneous computing part in the long term part of that slide???


might it mean optical interconnect ?????

Interesting question and I often thought about that. Optical interconnect is just a tech but likely not meant by fabric (which IMO describes the way compute units are combined). Instead we might see something like EDGE/TRIPS (which Chuck Moore worked on in the past) and Larrabee. At least this slide suggests sth like that:
Attachment 116279

Some options: smaller GPU cores spread across the CPU cores (short communication, less "reprocessing" and preparation -> higher power efficiency), compute arrays, reconfigurable computing. General purpose cores might become a collaborating set of small cores, accompanied by some bigger units for special workloads. As someone said, it might become standard to have more units on a chip (trannies are cheap) than power budget would allow to be active at the same time. Maybe I will elaborate that in more detail on my blog. No promises

Komodo is a CPU,but seems to integrate PCIe so it needs a new socket that will in turn accept also the Fusion Trinity class of APUs.

Komodo FMx socket should not be equal to Trinity FMx socket.
We don't need another LGA 1156...

[Oliverda]

Komodo FMx socket should not be equal to Trinity FMx socket.

Why?

[XRL8]

FMx designation seems to suggest there will be few types of it.
And it makes sense, as trinity has different needs than komodo.

FX-8150P (C0) - 4.0 GHz, Max T.C 4.4 GHz, 125 W (?)
FX-8130P (B2) - 3.8 GHz, Max T.C 4.2 GHz, 125 W (320$)
FX-8110 (B2) - 3.6 GHz, Max T.C 4.0 GHz, 95 W (290$)
FX-8100 (C0) - 3.5 GHz, Max T.C 3.9 GHz, 95 W (?)

Also, OBR is selling his 8 core BD for $420...
Wonder where he gets his chips since he seems to do whatever he wants to with them.

[Manicdan]

a C0 stepping thats slower than a B2 stepping sure sounds a little off
even if they can reach those specs (8110) with B2 there is no need for a lower model initial since they can earn more per chip, but why even introduce it later since prices will drive down over time anyway.

also a 30w increase for just 200mhz sounds pretty far off, going from 8110 to 8130P

based on that list i see no reason to buy anything other than the 8110 considering we know its not very power hungry and still a good solid 4ghz (and of coarse its unlocked)

[zalbard]

There are certain 'steps' when it comes to TDP ranking, so this is plausible.

Yeah, but C0 might overclock better.
Anyway, just rumours. Thought I'd post.

If you take into account the TDP is not expected consumption, but a way to keep board makers from shipping VRMs that double as toasters, it's not so far fetched: the 8130P may just hover above 95W, but that forces AMD to bump it to 135W. (Maybe another intermediate step would be better? Who knows.)

[XRL8]

I was under the impression P models are going to be unlocked, and the rest not.
How do you know all will be ?

[Manicdan]

There are certain 'steps' when it comes to TDP ranking, so this is plausible.

the point was, why stop at just 200mhz more (5% really), for 30% more TDP.

so if they needed a voltage bump, then the lower model might actually have more headroom. or this is showing the upper limits of their clock rates. the first is meh, the second is really scary to hear. the truth is it could simply be 105w and they just dont have enough for multiple skus, even though they could give us a 4.4ghz version up front already (in limited quantity or something)

this is all just nonsense speculation, please dont read too much into what i say

[Manicdan]

from the many people who have preached that all FX models will be, although i never believed them
the P to me seemed related to 125W models from patterns i saw

Interesting rumour... Fantastic if true.

This is the same many times regugitated rumour that started here on XS from the wrongly interpreted ASUS slide.
And it's already rubished by the fact max TC. is going to be +1Ghz (which was also evident from that slides).

As for OBR, that chip was supposedly 3ghz, yes?

[muziqaz]

I am pretty sure we will not see such frequencies at launch Though I would be very very glad to be proven wrong.

[doompc]

Why?

Komodo is not an APU, what's the point on making it compatible with motherboards with video outputs?

My guess is that Komodo will have 32+ PCIe lanes (if it does indeed have integrated PCIe) and HTT, kinda like LGA 2011.

[zalbard]

As for OBR, that chip was supposedly 3ghz, yes?

That's what he says, yes.

[rintamarotta]

Id expect to see Komodo have 48 PCI-E 3.0 lines, SLI/Crossfire with 16x/16x configuration and Trifire/TriSLI configuration 16/16/8 and it would still leave 8 PCI-E lines for other hardware.
Its AMD's top of the line system so why not have 48 PCI-E 3.0 lines for multi card configurations.

I watch carefully on his ES chip, form the string I read seems it's still a B0 chip.



EDIT: the number in the string is looked like '2620', means it's a 2.6ghz chip.

If it run superpi1M@15s that's good however take turbo into account.

[FlanK3r]

I think, this videospec is some fake....dont believe it.

That's weird because the performance is much superior to the 2 B0 chips CHH tested and the B0 on youtube. Also, iirc, B0s don't have turbo enabled.

Since few of those SKU will never exist i doubt that any information is accurate regarding GHZ and price.....

[Opteron146]

And it makes sense, as trinity has different needs than komodo.

No, few types would be suggested by a different designation like FMx and FMy ;-)

I think it will be the same:
a) AMD has still less volume then Intel, a special enthusiast plattform like intel's 1366 does not make sense for them. Intel's 1366 had around 2-3% volume of the whole market. AMD has something between 20-30%, now calculate 2-3% for that numbers. That's not much.

b) Triple channel only helps in certain special cases. Anybody remebers significant performance differences between socket 1366 and 1156 ?

c) FMx will probably be sth like FM1+ and just get a DDR3-2133 and PCIe3 Update. Maybe also a bit more TDP, ~125W. That is ~+15% RAM bandwidth and +100% PCIe performance, no need for triple channel or lots of PCIe lanes.

Conclusion:
Yes, the die hard XS enthusiast wants Quad Channel and 100 PCIe lanes, but the far most of the people will buy price/performance. For that purpose, Komodo@FMx will provide a solide base.

[Tomasis]

maybe i missed somewhere.. when are opterons coming? I suppose that they coming earlier than desktop version?

If there would be only one FM type of socket, whats the point of putting "x" there ?
It usually means "unknown number".
But i know what youre getting at.Keep in mind however, the while youre talking about small percentage of small percentage of market share, it doesnt stop amd from doing two different server sockets.
I just hope youre wrong :P

[=SOC= Admiral]

Well depending on how you guys do with yours I may just break down and build a new AMD box instead of waiting for the 22nm intels. Mainly im waiting on money to purchase. But these look extremely competitive and love the return of SLI.
