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.

    I hope AMD succeeds in Barcelona so I can get another Intel Quad processor for cheap. All this debate is rather comical. In theory and on paper Barcelona looks like the cream of the crop, but as of yet, AMD has not shown me anything but a pretty FLASH presentation of hopes for the future. (Now a much MORE distant furture.) No Benchmarks or finalized product. They sure can Market though. Too bad there's nothing to sell. Reply

    I can't express how dissappointing it is to see AMD in a bad way like this. It is true that according to current market trends, standards, and production - they're behind the curve, and there's just no getting around that.

    I see their potential - a road map that could culturally change the way a PC is built; we need that kind of innovation in the long run and AMD could pull it off, because they've done it before.

    However, that's as I said in the long run. For now, they're not achieving measured goals that can reflect the capability, competence, and trust invested by their own employees, management, and investors to accomplish goals in a timely, budget-effective process. While it may not be so important that Barcelona succeeds in the short term, (and I say that because Intel has thoroughly trounced over anything AMD will offer in this segment) these concepts are absolutely vital as AMD continues to explore systems that offer CPU / GPU capabilities on the same platform - or even upgradeable modules to the CPU / GPU for task-specific application. While revolutionary in concept, these are objectives that require a sustained, driven, and highly focused effort to achieve the dramatic results that would be needed to bring AMD back into the arena.

    What is difficult about the current situation remains the fact that company sustinance often exists in the court of public opinion (especially if it's publicly traded) - and AMD is only a few blows away from full-on "knock out". Intel is poised at the jugular, to be clear; worst-case scenario would be for (and this is very likely) Intel's '08 lineup to be introduced at the same time Barcelona releases (soft or hard).

    Now let me be clear: this doesn not mean AMD sinks. What it DOES indicate is that Intel will probably continue to be the leader for the next few years (at minimum).

    Good grief, stop being so melodramatic.

    Intel's '08 lineup is nothing. Penryn is nothing to worry about, it's a minor change and not as substantial as the Barcelona. I don't know why people exaggerate it so much, but I guess the uninformed make things up rather than deal with the complexities that not every change is the same in magnitude.

    AMD has been in way worse situations than this, and they are still here. I think the real issues come back to Hector Ruiz. This ass-clown has to go. He just has to. He's earning massive amounts of money while leading the company into the abyss. That's my real concern, not some small delay in Barcelona performance, but this piece of crap CEO that is screwing everything up. Maybe this demise will be a blessing if they dump this sorry sack of dung. He's killing the company.

    "Intel's '08 lineup is nothing." Compared to what? AMD's line up? Can you tell me what that will be?
    "Penryn is nothing to worry about" Who is worrying, well, other than AMD? Not you or I.
    "it's a minor change and not as substantial as the Barcelona. I don't know why people exaggerate it so much, but I guess the uninformed make things up rather than deal with the complexities that not every change is the same in magnitude."
    Ok, ok. I'm not trying to nitpick but c'mon. Melodramatic? Yes, Penryn is as Intel intended, an architectural update with some enhancements, a die shrink and additional performance. No big deal being made there. But c'mon, the only thing substantial about Barcy is that it is a major update for AMD. From a functional, performance or financial standpoint there is nothing substantial. It has yet to prove itself, at all. It in no was has had any significant impact other than to speculators. I have no idea why people pawn all over something they themselves know little to nothing about. I guess it called faith.

    Are you crazy?

    Barcelona is a very big change compared to existing processors. And there is a lot known about it, just you don't. We know all about the new communications, the new branching, the L3 cache, the non-speculative memory reordering (the biggest thing, probably), inter processor communication (unlike Intel's FSB between the two sets of cores), additional HT link, SSE128, double instruction bandwidth, etc...

    You are obviously uninformed, badly so, and assume there isn't a lot of information out there. They all add up to a pretty significant, although not revolutionary, upgrade to an existing product that isn't terrible. You need to learn more before making such a post, because it just comes off as uninformed.

    I do agree with one thing though, we do have to wait until we see the results. But, to some extent, if I drop a rock from a tree, I don't have to watch it fall to know it will. This isn't that absolute, but the changes are so predictable it's hard to believe this won't be at least a very competitive processor. But, I'll agree, we won't know exactly how competitive until it actually is ready.

    Quite frankly - I just thought you may wish to know that the tone of your posts thus far have been perceived by myself to be arrogant, cock-sure, egotistical, and disrespectful. I think you would do well to adjust the “attitude” of your future posts, as it would prevent me (as well as other readers I’m sure) from needing to pause every 4 seconds, stop concentrating on your actual message, and attempt to sift out your emotional baggage from the occasionally relevant fact or point (too few or far between, unfortunately).

    That being said – I’m not going to spend time sorting point vs. counterpoint to your objections raised. I will simply state that it would be impossible for anyone to read all of the above posts and not come away with the belief that you’ve contradicted yourself on more than one occasion.

    We have seen very recent examples of supposedly “predictable” (the term you used) changes or innovations in architecture and performance for AMD, which in the final release did not even see the light of day. We’ve also seen efforts to correct inherent flaws in the design with additional hardware component modifications, additions, or even the occasional software driver revision where said “innovations” did occur.

    AMD is now a CPU and GPU industry provider; ultimately under the same management, and currently in the process of being aligned to the same overall business strategy. I don’t need to be the most technically knowledgeable person on this form to understand that AMD is not in a good position right now.

    Your posts seem to indicate a belief in the performance of this “holy grail” of an AMD chip, the revered Barcelona, as being the winning stroke that sends AMD back to the top in the server sector, and perhaps on a more global scale (which couldn’t be further from being the case in actual reality).

    I and others are simply attempting to examine what we feel to be potentially more significant factors than the simple success or failure of a single chip. Actually, we’re interested in discussing the factors that would actually determine the success or failure of the chip in question – a discussion which apparently is lost on you.

    My post did not claim to be “the most correct gospel on AMD as they stand” (as did every post you have ever made since). My post did cite my simple opinion, while allowing me to enjoy the feedback and insight of others in this forum (as was not the case with every post you have ever made since).

    In all reality, I really think you should consider working for AMD so you can actually get paid for all of the promoting you’re doing on behalf of their up-and-coming product. Then again, considering your appeal with the consumer market represented here - I’m not so sure they would be interested.

    Do I think AMD has a lot of potential? Absolutely! Do I fear for their current and future success? Yes; if they don’t start making some dramatic changes to their strategy as a whole. Am I hoping they will be successful? I most certainly am. Do your posts irritate me? That was a rhetorical question.

    Not really crazy, just well, not extreme.

    Oh, I think I might known a little bit. And it appears that you do as well, at least what the press reports tell you. It's easy to copy and paste isn't it. And what does all that mean to the market place, the consumer, to AMD's bottom line? Nothing. It is all unproven and just talk. Talk that the closer we get to AMD launch schedules the shakier their execution ability appears.
    It's funny how you bang on Intel FSB, SSE, cache usage etc... yet these are features you tout with AMD. Does hypocrite come to mind? Yes, these features should be mention when discussing BOTH processor as these are some of the features that improve performance if done properly. Just because the parts are there doesn't mean they will work together. Proper design and integration is what we waiting to find out.

    You are obviously uninformed, badly so, and assume there isn't a lot of information out there.

    Really what part? Or should I say parts, as you seem to believe you really have the market cornered on microprocessor design. Go ahead, pick them out and educate me, please go ahead.

    I do agree with one thing though, we do have to wait until we see the results. But, to some extent, if I drop a rock from a tree, I don't have to watch it fall to know it will.

    Hmmm, and after all your harping and insinuations that we are all idiots, you end with that? You agree we have to wait and see how competitive Barcy is. I'm sorry, but that's ****.

    I don't know what is your definition about minor change, but Penryn will offer at least 5-10% higher IPC with at least 15-20% higher clockspeed. Thus Penryn will bring about 20-30% improvement compared to current Conroe which is quite substantial in my opinion.

    None of the changes to Penryn were for clock speed, and your 5-10% is a made up number. If you see anywhere close to this, you'll only get it from the larger cache, which again is NOT architecture. The actual architecture changes are very minor, and not even in the same ballpark as the Barcelona. The problem is when people talk about it like it's a lot more than a die shrink (which allows for the larger cache, and possibly greater clock speeds), which it isn't. Even Intel doesn't categorize it as such, just a die shrink with some minor tweaks. Their bigger changes will come after this.

    Penryn clocking higher isn't clear either. They will release it at higher clock speeds, but the Conroe could be sold at much higher clock speeds if Intel wanted to. They just haven't seen much need to. So, if Penryn peaks at 3.6 GHz, I'm not sure that shows any progress in clock speed since getting a Conroe there is not difficult. I'll be curious to see how well it overclocks to see if it can hit over 4.4 GHz which would represent something close to a 20% increase in the real frequency limitation. The released numbers will be way higher, mainly because AMD's chips will be so much more competitive, they can't dog them with artificially low clock speeds.

    No it's not. See Anandtech article about Penryn benchmarks, in some cases clock-to-clock improvement is much higher.

    Who cares? Customers care about performance, it's irrelevant wherever the performance is achieved by larger cache, higher clockspeeds or some other changes. Penryn will produce substantial performance improvements compared to Conroe.

    I seriously doubt that Intel could release quad core 65nm at above 3GHz with a reasonable TDP. Penryn based quad core CPUs should easily achieve higher clockspeeds.
