Barcelona Clock Speed and Release Schedule

The CPUs themselves work, once again, as we've seen from AMD's own demos. But the real question we've been asking has been "at what clock speed?" The chips we saw at Computex ran at either 1.4GHz or 1.6GHz, the latter being the latest B01 stepping. AMD's Tier-1 server partners are starting to see 1.8GHz chips, but that's the fastest we've heard of at this point. We understand from the motherboard partners that AMD should hit 2.0GHz by September for the Barcelona launch, but according to AMD the partners will see at least 2.3GHz by the end of summer.

The motherboard makers we talked to are divided about how many more silicon revisions they expect before an official launch for Barcelona. Some expect to see two more revisions, while others expect a single rev after B01. If the next revision of the core yields are high enough, AMD may do a very limited "public" release in July at 1.6GHz - 1.8GHz just to get product out there for release purposes.

None of the partners we talked to are really impressed with Barcelona yet, but then again none of the true potential of the chip and chipsets have been realized due to CPU stepping issues, BIOS maturity, and generally low clock speeds. AMD simply hasn't gotten the process under control yet and after hearing our friends at the motherboard companies talk, AMD is close to near/total panic mode right now as the Q3 Barcelona product launch schedule rapidly approaches.

The general consensus is that until AMD gets to at least 2.0 - 2.3GHz, we will not see any significant volumes of Barcelona chips in the channel. Alternatively, AMD may delay the actual launch until September, with true volumes hitting the channel and partners by November. If this worst case scenario pans out, we're hearing that Agena would be pushed out to Q1 '08, or a slightly better option being a small trickle of Agena into the channel by December to keep AMD's Christmas promise.

Continuing on the worst case scenario track, some partners don't expect to see 2.3 - 2.6GHz Barcelona parts in volume until Q2 next year, and based on AMD's simulations the processor doesn't come "alive" until it hits the 2.6GHz mark. At the same time, others have said that an earlier stepping of the core was overclocked from 1.8GHz to 2.5GHz without too much trouble. All in all it's tough to say what clock speeds will be possible and when, but we do know for a fact that what we saw at Computex (Barcelona) ran slower than 2.0GHz.

One interesting rumor that we heard on the plane back home is that Agena parts are likely to scale to higher speeds quicker than Barcelona. The reason for this is getting the server oriented Barcelona to work reliably in 2P or above configurations is a leading factor in the reduced core speeds expected at launch. According to our sources, AMD seems very confident at this point that a 2.6GHz Agena part is likely when this processor series launches on the desktop. Of course, the question being just when is AMD planning the launch of Agena. We expect the product to be introduced publicly in the October time frame but actual availability dates and volumes is anyone's guess at this point.

The biggest story in all of this is that AMD is just not ready yet, the chips are not scaling well, and today it's looking like Intel may eat their lunch the rest of this year. AMD seems very optimistic with internal roadmaps showing 2.9GHz cores by Q1 2008, but everything we've seen or heard today makes this seem unlikely. However, as the original Athlon64 launch showed, AMD is certainly capable of surprising us and we certainly hope they do. For all of us who have been crying for Barcelona benchmarks, you really don't want to see them yet. Performance will improve quickly over time, but it's just not there today.

    Well CobraT1, I think he has NO idea about CPU manufacturing and cost, at all.

    Barcy would be significant for AMD, but no for PC industry. There is no way it can compet with Penryn. The very first Penryn (1st tapeout) runs up to 3.7Ghz in Intel lab. Even if it can reach 2.8Ghz as AMD simulated, it won't beat Penryn @3.7Ghz.

    AMD was/is and will be in trouble. They have to wait until their 45nm process is up and run. Before that, they have no chance.

    Well, if your car is turbocharged, 50HP is often just an ECU flash away. If you have a supercharger you can put on a smaller pulley. No guarantee on how well the rest of the powertrain will hold up, but it can be done. The VW 1.8T engines supposedly respond well to just changing the intake manifold gasket. The RB26DETT was reported to pick up over 100HP from just camshafts and an ECU flash.

    Back to the subject of processors, I agree that the size of the leap over it's predecessor won't matter much if Barcelona can't at least match Penryn. Also, IIRC, Nehalem is scheduled for release next year, which is supposed to be a more significant update. So even if Barcelona outperforms Penryn, AMD can't wait nearly so long to pull their next rabbit out of a hat as they have for this update.

    Also, if I were a shareholder of AMD, I'd be concerned that if they do get delayed to the very end of this year or early next year, then the earliest they are going to return a profit is Q3 08. As mentioned elsewhere in the comments, companies don't generally rush out to upgrade their servers, and the majority of consumer purchases are in Q3 and esp. Q4. So if AMD can't have the new processors on the shelves this year, that will be two Christmas buying cycles in a row where they have played second fiddle to Intel. That won't help their bottom line.

    I understand what your saying, that it is possible to boost power output of some engine designs, especially designs that were poor to begin with. Yet, the point was to increase overall power without suffering losses, and it being easy. Like with processors, this is generally not a quick and easy task and concessions generally need to be made. It takes proper consideration of usage, limitations, cost and the understanding of how the components will work in concert. With software modifications of engine managements systems (ECU) it is just as easy to reduce performance or negatively effect other operational criteria with programming. Testing needs to be done, hence the usage of dyno's in graphing power profiles and monitoring function. And generally, with no other modifications the power profile will change. Gains will be made under certain speed\loads while losses will be seen under others. Efficiency also generally drops. For example, modifications can fairly easily be made (like throwing on a larger TB) to produce a higher peak hp, yet throttle response, low-end torque and efficiency will generally suffer. That would not be an ideal design choice in regards to what we are analogizing. Induction velocities, capacities, fuel atomization abilities, fuel mixtures, cam\valve timings, valve lift, duration and I\O overlap, combustion chamber size, CC shape, plug choice, Ign. timings, duration and intensity, I\O port shape, size and length, scavenging and\or back pressure, the list could go on and on. The point is, if you change one it effects the others, and like in processor design these components need to be designed in such a way that the hole functions as was intended. If an increase in overall performance and efficiency is the intended target, you generally can’t just add something to achieve this. Even just adding cache in a processor design has it positive and negative impacts.

    I suppose I didn't read that correctly. Yes, if a company wants to add more power they need to research it extensively. However, the consumer can just go buy the results of that research, so for them it is relatively easy.

    That's funny comment. Hector has devoted his life to fight with Intel since Motorola days with 68000. But we can forsee he won't make it. CPU industry is not just design or execusion. It's capital/manufacturing.
  • TA152H - Monday, June 11, 2007 - link

    Yet, it was design, under Jerry Sander's leadership, that made AMD what it is today. Or was, except Hector now has given up that leadership in design. They waited too long. He was never known as a visionary, but was supposed to help with execution, which hasn't exactly worked, has it?

    Where is the 68K now anyway? That's a good example of his prowess. A much better processor with a much more elegant instruction set is essentially dead, although Freescale still sells something close to it with a scaled-down instruction set. If the 68K line had the 68008 in time, would IBM have chosen the 8088? Doubtful, since they used the 68K in their 3270 and 370 emulators, not an Intel product. It's not like the 68008 wasn't possible either, it's somewhat simpler in that it has few address lines and data lines. So, where does he deserve credit for this???

    Anyone else thought that Shittle's SFF cases are getting bigger? With their G2 and G5 models, they looked great with their compact designs. Now it seems that Shuttle's cases are simply mid-sized towers turned sideways.
  • erwos - Tuesday, June 12, 2007 - link

    Shuttles are a touch larger than they used to be, but let's face it: you just can't cool a modern quad-core CPU and a high-end GPU without a little extra space to work with.

    They are _nowhere near_ the size of a mid-tower. The SS21T is a touch larger than most, but everything else is far smaller.

    That AMD did not spend 3-4 years of R&D on this processor. More like..6-12 months. They started when they first saw Pentium M or was it when they first saw a Core Duo? I'm thinking when they first saw Core Duo because AMD made die shrinks before without updating the architecture. Though it seems like most of the time in development for the "Bark" has been making it work on a platform.

    All I got to say is what the hell was AMD thinking? They don't even have their mid-range video cards out yet and that's if you don't all ready consider their "flagship" middle range.

    That is simply not possible. It takes much longer than that to get a new piece of silicon out the door.
