AMD "Barcelona" die shot  (Source: AMD)
AMD's next-generation launch date is still set for "summer 2007"

AMD is set to debut its third-generation Opteron server processor architecture later this quarter. The company publically announced its upcoming launch next month, but the company's latest processor guidance, released just this week, states otherwise. 

According to partners close to AMD, sampling for Barcelona processors will hit top tier system builders this week. One engineer speaking on conditions of anonymity claims, "We're finally getting close to a launch here, but [AMD] still hasn't finalized the date."

The August 27 launch date originally featured on the last Barcelona roadmap, issued less than a month ago, has since dissapeared.

AMD plans to offer initial quad-core Opterons at core frequencies below 2.0 GHz. The company will launch eight quad-core processors under the Opteron 8000 and 2000 series umbrellas. Standard and high-efficiency (HE) models are ready for launch later this quarter.

AMD has three quad-core Opteron 8000 series models in two speed grades for launch – the 8350, 8348 and 8348 HE. The processors will ship with 2.0 GHz and 1.9 GHz clock frequencies, respectively.

Quad-core Opteron 2000-series will have a similar launch schedule with the 2348, 2350 and 2348 HE. These models are identical to the Opteron 8000 series, except the chips can only operate in two-socket systems. The quad-core Opteron 2000 series also gains two lower speed variants – the 2346 HE and 2344 HE. The quad-core Opteron 2346 HE and 2344 HE feature 1.8 GHz and 1.7 GHz clock speeds, respectively. This concludes the quad-core launch lineup for the quarter.

AMD plans to launch the initial batch of quad-core Opterons this quarter. However, customers will not receive initial DVT samples until next month and actual production for customer order fulfillment does not begin until September. AMD still does not have an exact launch date set, but the AMD roadmap states a summer 2007 launch and autumn begins on September 23.

AMD will ramp up clock speeds of quad-core Opteron 8000 and 2000 series in Q4’2007, with the first quad-core SE models entering production. Eleven quad-core models with clock speeds excess of 2.0 GHz will enter production in Q4’2007 with an undetermined launch date. The new models will top out with a 2.5 GHz clock-speed. AMD promises DVT samples of the new models in early Q4’2007.

AMD also has five quad-core Opteron 1000 series models in the pipeline. These models are only available in speed grades above 2.0 GHz. AMD has three models ready for production in November – the 1356, 1354 and 1352. DVT samples of theses processors are available next month. Higher-clocked 1360 SE and 1358 SE models will enter production in December, with DVT samples available in October.

Expect AMD to launch the first set of Barcelona-based quad-core Opteron 8000 and 2000 series processors later this summer.

What are you smoking? Quad core Phenom is nothing but a Barcelona in a different socket.

Since Barcelona can reach 2.5GHz@120W in Q4, how on the earth can quad core Phenoms reach 2.6GHz@65W at the same time??

Um, no...
1. Phenom is HT 3.0 and Barcelona is HT 2.0
2. Phenom has split power planes, Barcelona may not
3. Barcelona must be qualified for servers, Phenom doesn't
4. Barcelona has more HT connections

There are more differences if you look

I forgot to add probably the most important difference...
The memory controllers are quite different between the desktops and the Opterons. The servers require buffered ram that's shared to any other cHT source through the cache and the desktops do not.
That could very well account for a diference in clockspeed...

Memory controllers are exactly the same. Support for ECC/buffered RAM is just disabled for desktop products.

If you disagree with me, then please tell me the difference at chip level between following chips:

Athlon64 (FX) (Windsor): 2x1MB L2, 227M transistors, 235mm^2@90nm
Opteron (Santa Rosa): 2x1MB L2, 227M transistors, 235mm^2@90nm

What you describe is the difference between sockets AM2 and AM2+.

AM2 is HT2, and does not have split power planes, while AM2+ has split power planes and HT3. That being said, Barcelona chips can run in AM2 and AM2+ sockets, so, if run in an AM2 sockets, they will function as you described - without HT3 and split power planes.

The new Opetrons and Phenom chips both use Barcelona core technology, which is mostly exactly the same, except for the memory controller to handle buffered and registered memory, and the fact that Opterons (depending on the model) use different sockets and are suitable for MP configurations.

Look it up on Wiki and Anandtech's articles on Barcelona if you dont believe me.

You're thinking desktop (Barcelona is 1207, not AM2)

Doesn't matter the exact same difference applies.

The server end has 1207 and 1207+, only the + motherboards can use the split power planes.

Its a chipset thing, not the CPU.

I can't believe they'll have 65W 2.6 GHz components and 120W 2.5 GHz components out at the same time... 95 and 120 maybe (just due to the rating system), but not 65/120.

Power consumption is much more critical for servers & workstations that run 24/7 than desktops. Hence why AMD are producing low powered variants of Barcelona now and going for higher speed later (the low power chips will still sell in big numbers).

It absolutely has to be both.
Think about it...without a change to the structure of the chip, how could a chipset effect voltages on each individual core?
You couldn't (for example) control the power of individual cores if you used an AM2 chip in an AM2+ mobo, even though the chip will still work within it's limitations.

BTW, individual control in realtime of individual core voltages should drastically reduce both power and heat...

Yes, it is a CPU and chipset thing, sorry I mistated that in my last post.

But what I meant, is that all K10 class CPUs offer split power planes and HT3. All. Everyone.

Barcelona, Kuma and Agena all share those features.

AM2 and socket 1207 do not, thus any K10 in those sockets will not use them. But, as soon as you put said chip into an AM2+/1207+ slot, it will use them.

The Barcelona server chip does not...it's not 1207+ capable.

Same thing for 1207 and 1207+.

Please, look it up. Honestly, its a chipset thing, its NOT a CPU thing.

1. Is this a limitation of a core or a socket?
2. Split power planes are function of a new socket, Phenom in AM2 socket will not support split power planes
3. Doesn't make any difference from the hardware point of view
4. Doesn't make any difference from the hardware point of view, current Athlon64 FXs are just Opterons with some HT links disabled

As a result, I still claim that quad core Phenoms will be using exactly the same Barcelona core as Barcelona based Opterons. Only socket will be different and some things maybe disabled in Phenom.

In any case, these things aren't significant enough for account for HUGE difference in power consumption: 2.5GHz@120W vs. 2.6GHz@65W claimed by you.

Both are required...
quote:
2. Split power planes are function of a new socket, Phenom in AM2 socket will not support split power planes

Again, both are required...but the change is built into the core. It also requires a modified socket to access it (AM2+ or 1207+).
quote:
3. Doesn't make any difference from the hardware point of view

It is a limitation on bin splits and 100% guarantee of backwards compatability.

I think where you guys are confused is that the tech is called Barcelona, and the new server chip is called the same.

The first fully K10 server chip will be Agena (due in Q1), not Barcelona (which is a hybrid that is fully compatable).
They are entirely different steppings and designs...

Barcelona is what lots of people are referring when they are talking about K10's as a whole in addition to the Server variants coming in for Q3 2007.

What the heck are you referring to when you say "first fully K10 server chip" you mean the fact that it has HT3.0? Agena won't be able to access ECC/Registered Memory, so it's only going to be used in Opteron UP and Desktops.

Entirely different is a bit of stretch, they are so similar as they are both K10 technology.

Split power planes have to be built in to the architecture, but they have to be supported by the motherboard as well. You can't just magically add split power planes in to an old CPU by putting it in to a new socket.

I think people are making very poor speculative analysis here, we won't know the real difference until it comes out. But if they are exactly the same with a few things disabled, then they at least won't have any trouble coming out with the Phenom CPUs before Christmas, at least for the lower clock frequencies.

That's because thr SKU's Viditor is refering to are Dual Core's not Quad, so 2.8GHZ is projected at 89W.

Anyway these are the TDP of the 2 models as follows Phenom X2 GS-6550 (2.2GHZ-2.6GHZ) and Phenom X2 GP-6800 (2.4GHZ-2.8GHZ).

Both Agena variants will come in at 89W which is the desktop equivalent of 95W.
