AMD shipped X6 phenom 2 chips out this week

Fry's has had them up on the boards with pricing and exact specs for several weeks now, bay area stores have the 1055T in stock as of yesterday, with this info easily accessible to anyone who walks into fry's and asks. launch within the next 2 weeks? pricing on the 1055T is $199.00 for anyone who cares
 
Interesting. Does anybody have an NDA expiration on this? I would expect more AMD announcements by this point.
 
I guess they smuggled it from china or HK. There is a guy selling a 1055T for $350 on ebay from china, looks fail to me though.
 
system wont tell us, i would have to call the buyer directly to get that information, and he's under NDA probably
 
I ordered a 1055T today here in Canada for $210 and will apparently get one by next Friday...will post my OC results when I get it.

EDIT: Had to cancel my order since Gigabyte said they won't update my motherboard BIOS for a couple of weeks.

Pretty neat at that price. Not really tempted to switch but if I was doing a new build that'd have my attention...
 
My MB was the one that Gigabyte "accidentally" put the X6 support on their website for, MA770-UD3, and I think there's already a BIOS for it. This excites me! I haven't upgraded anything since I bought my 5770 a couple of weeks after launch. Faster encoding makes me happy.
 
No. AMD does not have hyper-threading now, nor will they have it in their next arch (Bulldozer).

No, Bulldozer won't have HT, but a BD module can handle 2 threads. Then again, I didn't see any 6 BD module chip anywhere on the roadmap so I don't think we're going to see any AMD offering with 12 thread capacity anytime soon (at least for desktop segment).

That's right, but that doesn't answer his query. Bulldozer won't be marketed "per module". Instead, it will say "4 cores" or "8 cores", each core being 1/2 of a module. So a quad-core Bulldozer will still only have 4 threads, and an octo-core Bulldozer will still only have 8 threads. Even by Bulldozer, AMD will still go by 1 core = 1 thread, none of the "1 core = 2 threads" expectations he has, which is why I opted to answer him that way without mentioning modules since that is a technical detail.

Point taken. 😛

AMD multi-threading on a single 'core' is called CMT. They have not 'officially' said BD will support CMT (which is now commonly called 'Cluster-based Multi-threading') but what they have said is that their implementation is nothing like what Intel does with hyper-threading.

My understanding is Intel takes duplicate thread instructions and executes in the same pipeline. AMD will fetch duplicate thread instructions and execute two pipelines across a 'module' with 2 integer schedulers, each having their own dedicated chunk of L1 data cache and shared L2 and L3.

As you guys have noted, this is where AMD is 're-writing' techno-speak somewhat in that they reference a module as having two integer units or 'cores'.

The first desktop Bulldozer (Zambezi) will contain four modules for a total of eight 'cores'. Enterprise Opterons will combine six or eight modules (Valencia and Interlagos) for a total of 12 or 16 'cores'.

The 'scaling' across modules is said to be spectacular --- near 96% in some instances --- as opposed to the Intel HT.

You will be tested later --- 😀

Clustered multi-threading is not HT at all. That is just the way they will handle multiple threads across real cores, unlike HT where existing "real" cores do extra work. CMT exists only because they grouped together 2 INT with 1 FP packed together in a "module", yet they want to count it as "2 cores" instead of a single core.

We have had a long thread about this already when the AT article about latest AMD roadmap was published (I initially hoped Zambezi 4 cores = 8 threads, but in the end had to accept it wasn't so), where even JF-AMD cleared that up, as well as the peformance benefits against HT (roughly: HT -20% performance, compared to 80-90% for "real" cores). A quad-core Zambezi then is [two modules / four cores / four threads]. There is an octo-core Zambezi as well which means [four modules / eight cores / eight threads].

I doubt we should go into that in this thread again, especially if it will derail the conversation more.

EDIT: Found the original, extremely long AT Forums thread about Bulldozer.

That is very cool and it will have HT right ? You have 12 threads like Intel or what... gl

(OT) - hey, welcome back, tweakster! Now don't forget to wipe, and stay off the pipe... 😀:thumbsup:

Edit - I must say, it is an impressive sig (compared to mine, at any rate..hehe)

Edit 2 - btw, what happened to Idontcare, anyway?

Many people have asked that question, and it just shows how much he contributed to this forum. I do hope nothing bad happened to him.
