AMD Announces August Release Date for Barcelona

An anonymous reader writes "Rumors said the release wouldn't be until late Q4 but an August ship date is now promised for AMD's quad-core chips. They're only releasing up to 2.0 GHz processors at first, with the top speed devices coming out later in the year. 'AMD's Barcelona puts four cores on a single slice of silicon, an approach AMD calls native quad-core, and the company has argued that Barcelona will outperform the Xeon 5300. The only problem: that comparison soon will become obsolete. Intel's second-generation quad-core server processors, Harpertown a server member of Intel's Penryn family, will arrive this year, too, with the promise of better performance, lower power consumption and lower manufacturing costs by virtue of a manufacturing process with 45-nanometer features. AMD is only just now moving to a 65-nanometer process.'"

Lower Manufacturing Cost?

[enjerth]

Lowering the costs of manufacturing may be nice, but I don't think it's a particularly significant factor in their pricing model.

Thanks, anyways.

Re:

[enjerth]

I should have clarified.

RE: Intel's Penryn family mentioned in the summary. Yeah, AMD may have higher manufacturing costs, but they're cheaper! DUR!

Re:

[edwdig]

Lowering the manufacturing cost doesn't make a huge difference on the price marketing sets, but it makes a huge difference on what the engineering team does.

The engineering team is given target transistor count based on expected manufacturing costs, which affects the cache size and feature set.

Marketing and hubris may have done AMD in.

[RightSaidFred99]

They were so vocal about "true dual core" and then "native quad core", they made it sound like it actually meant something important. Now they're paying the price - they can't manufacture it. All indications I've heard are that they're having production problems. Compare this with the alternative of just gluing a few dual cores together.

Looks like you're mocking the outcome of a future event that has not happened yet.

IT is a funny place to be: sometimes when it seems you're a total loser, you are, but sometimes, you come on top and kill the competition.

It's all about the details, details which you don't know.

True enough. I can only judge based on known information and rumor because, well, there's nothing else to judge on at this point. Based on those things it ain't looking good for Barcelona.

Marketing hype is not relevant. It's not relevant when it's true. It's not relevant when it's false. It's not relevant when your marketing predicts a win and you win. It's not relevant when your marketing predicts a win and you lose.

All the fanboyism and taunting and one-upsmanship and told-you-sos are worth exactly zero dollars.

The chips will perform the way they perform. There will be benchmarks. People will buy based on cost vs. performance decision-making, not cost vs. hype decision-making.

When the products are essentially the same, then the marketing matters.

But not like the original poster meant -- he was saying AMD would be proven wrong about some hype-full marketing assertion and somehow "lose face" or something. It doesn't work that way. Hype is forgotten. If you remember it, you don't understand it.

Re:

Incorrect. As I clearly explained, my point was that AMD's insistence on "native quad core" may do them in because they can't manufacture the thing. Them losing face is more amusing and gratifying than meaningful.

I have noticed in the audio world (and I'm guessing in other areas too) it only works like this when Intel is ahead. When AMD is ahead a large number of people carry on buying Intel because it is Intel. It sucks to be AMD.

Re:

[RightSaidFred99]

How are my comments odd? AMD is releasing Barcelona at a slower than expected speed. Now I know GHz ain't everything, but the fact is that for a chip this delayed they had to come out strong and they're not. My assertion is that this is because they're having problems getting good yields and enough higher clocking CPUs. They're trying to produce a chip that has 4 cores and add to that that it's on a relatively new (to AMD anyway) process and things don't look good.

Re:

So you're saying AMD shouldn't mentioned the only reason Intel beat them to it is the fact that Intel cut stupid corners to produce a product for the sake of being first?

Stability of AMD server chips certainly shows that AMD has an idea about SMP while Intel is still scratching their collective balls. When things go to 64 bit you really start to see AMD's strengths as their current offerings are more than competitive.

If any of what you said was true, you'd have a good point. Unfortunately Intel's chips outperform AMD's in 64-bit as well, just by a slightly smaller margin. What you call "cutting corners" is actually called "making money". A business doesn't release something first for the sake of releasing something first, they do it to make money.

Intel "cut corners" because they know they can get very good yields on the parts that way, hence making money. Now, if this part performed badly then you'd have a point,

I have no idea where you get your information. On the 64 bit end of things the Opteron has been hammering the Xeon for years. This is the area I have experience as I run a website which sees millions of users. The Opterons in addition to being more stable also perform a hell of a lot better. The numbers add up too as integer performance has been a strength of AMD for quite some time.

Re:

My other point was that AMD has mocked the "glue 'em together" approach.

And rightly too. AMD has a proper chip-to-chip interconnect (Hypertransport), which makes the "glue 'em together" approach unnecessary and undesirable. On an AMD system, you just plug in another CPU. On an intel system, the font side bus architecture makes this approach quite ineffective.

Never mind, intel will be bringing out its Hypertransport competitor in 2008, a full 5 years behind AMD.

Re:Marketing and hubris may have done AMD in.

[semiotec]

I really hope that AMD can pull themselves out of the current slump.

Their technology have always been competitive with Intel, regardless of whether they are holding the performance crown of the moment, and thus they provide the only true competition to Intel in the mainstream PC market. Unlike Via or the defunct Transmeta and others, which only managed to compete in some niche markets.

we'll see who's laughing when they're "next gen" chip underperforms (in many benchmarks, I'm betting)

Should AMD go down, even Intel fanboys are going to feel the pain when Intel starts ignoring the cheap segments and prices CPU whatever way they feel like. In a way, it'd be a worse monopoly than Microsoft, since it's much easier to create software from scratch than it is to create hardware from scratch. If the unthinkable happens, we can only hope that IBM (or maybe Sun) becomes interested in making x86 chips enough to provide an alternative, or provide cheap Power processors for desktops...

Personally, I don't care who's got the highest performing CPU, as long as I can get cheap CPUs that will do the job adequately.

Re:

[Kjella]

I think that without AMD, Intel itself will actually go down in a slump. For most consumers faster CPUs are now "nice to have". Throw in the cheapest dual-core processor you can find and 2GB RAM (which has also come down a lot in price) and you got a very cheap yet powerful and responsive machine that'll run pretty much everything for a non-gamer.

You assume that Technologically superior products are always more successful than their inferiors, and that AMD's multiple core solution is in fact, inferior.

for my first point, I would remind you of BetaMax, and Windows; BetaMax had technological superiority than its competition, but lost (Largely because of cost & capacity) To VHS; whereas Windows was vastly inferior to its competitors yet somehow managed to end up with the largest market share.

As to my second point, AMD's design seems to have some ad

Re:

[RightSaidFred99]

AMD's solution is provably inferior. It costs more to manufacture, has poorer yields, and doesn't perform as well. In fact, VHS was provably superior to Beta contrary to the urban legend. It had more capacity and hence provided more value to the customers to who it was marketed. You seem to confuse some kind of "engineering superiority in a few narrowly defined categories" for "meaningful technical superiority". The two are orthogonal.

That's a nice thought, except it's totally wrong. All their Brisbane core X2 chips are on 65nm now, and have been for quite awhile.

Re:65nm?

[samkass]

AMD has been shipping 65nm CPUs of one kind or another for about 6 months now. However, the Athlon X2 line still has many 90nm parts in its lineup-- they're still in the process of moving to a 65nm process, as the comment notes. So "totally wrong" is probably less correct than the original statement.

Not ruling AMD out

[tjstork]

Moving to native quad core has a lot of advantages and I'm actually excited to see how well this CPU will perform. Critics that claim that AMD lags behind in the process size would do well to note that AMD has ALWAYS lagged behind Intel in that category, and, yet, has managed to not only survive, but prosper.

Re:

[2nd Post!]

Releasing a product in a timely also has a lot of advantages
Releasing a performance commanding product also has a lot of advantages

Currently Intel is king of the hill on both counts. If AMD has a 2GHz quad core, Intel could match with a 4GHz quad core ON THE SAME DAY.

It is very hard to believe that AMD will be able to field a 2GHz part with 2x the performance of Intel's chip... that is what would be required to show a 40% performance advantage.

Re:

You are erroneously assuming that clock frequency matters across different designs. If I were to tell you I could sell you a working chip at 10Ghz would you want it?

[cartman]

Critics that claim that AMD lags behind in the process size would do well to note that AMD has ALWAYS lagged behind Intel in that category, and, yet, has managed to not only survive, but prosper.

AMD has always lagged behind in process technology, however they've usually only lagged behind by a few months. Now, however, the lag is more significant since Intel is moving to 45nm soon, while AMD is still in the transition to 65nm. I can't remember a time when AMD was nearly a full process generation behind.

..AMD has survived, true, but it hasn't prospered. AMD's split-adjusted stock price is about the same as it was in 1985. And AMD has taken significant losses in a great many of the intervening years.

When AMD has prospered, it usually was because Intel management had made some colossal strategic mistake and AMD exploited it. For example, Intel management decided not to design a successor core to the PPro/PII/PIII until AMD had released the Athlon, because of their confidence in Itanium. And Intel strenuously resisted going to 64 bit on x86, again to protect Itanium. And Intel delayed multicore processors. In all of those areas, AMD was able to beat Intel to the punch, not for technical reasons, but because the people who run Intel made strategic mistakes in direction, over and over again.

However Intel can bring colossal resources to bear, which matters because making CPUs is the most capital-intensive industry in the world. Intel has tremendous innate advantages because of their economy of scale and easy access to capital. Whenever AMD gains an advantage, Intel stops doing whatever stupid thing they were doing and re-commits themselves to beating AMD at the x86 game. When Intel isn't on the wrong path and isn't making silly mistakes in strategy, they almost always beat AMD and force AMD into heavy losses.

This time, Intel doesn't appear to be making any silly mistakes, which is terrible for AMD. Not that I think AMD will go bankrupt anytime soon, but I suspect AMD will have a few "lean" years, like they did when they were selling K6's.

Re:

Re:

the bottleneck is the dvd read/seek speed and IDE/ATAPI's single read channel limitations.

The meaning of the term "ripping" (CDs and DVDs) has changed over the years to include ripping and encoding. I personally don't like this definition, but it seems to be the accepted defn nowadays. "Rip the CD to MP3s." "Rip the DVD to XviD."

I agree with aegl. Many video encoding/transcoding apps have been updated to effectively use 4+ cores.

Re:

[Slack3r78]

Is this a joke? Video encoding is a task that's relatively trivial to parallelize and is one of the more common tasks that receives pretty massive speed ups from it.

The average DVD ripping guy is going to see more benefit from a quad core at this point in time.

Re:

Out of curiosity, how many video encoding applications support more than one core? The average user probably uses a one click solution to produce their dvds. Most of those tend to support only 1 cpu (are there any that don't).

It is unfortunate, because the only reason Intel killed off the poorly designed Pentium 4 was the strong competition, and the only reason you can buy a Core 2 Duo for under $150 is the competition from AMD.

Intel will also be coming out with a similar technology called Extended Page Tables or EPT, but AFAIK their timeframe is early 2008.

Not as simple as 65 v 45 nm.

AMD is using SOI, which as I understand, produces some benefit over Intels process at a given process size. If the benefit offsets 65 v 45, or comes close, I don't know.

I've written video processing code using SSE, and it makes a substantial speed difference. I haven't looked at the numbers recently, but my recollection is about a 30% reduction in run time. Beyond having to learn more assembly language instructions, writing for SIMD is not terribly difficult. Writing for a multicore processor requires learning about threads and paying attention to data timing, which I find quite difficult.

Re:

[Chandon Seldon]

Yea, video processing code is the poster child for SIMD - a 30% runtime improvement there over no SIMD is quite reasonable. On the other hand, the difference between SSE2 and SSE3 for the same code is probably somewhat smaller. In other areas, SIMD doesn't help at all, or only helps if you use techniques that are much more complex than multi-threading code.

Another interesting development is GPUs as general purpose SIMD processors...

Well, SSE matters much in HPC code. Intel compiler has quite decent vectorizer which helps a lot. And writing vectorizeable code is not that hard, actually.

Re:Cores and process are nice, but what about SSE(

[larry bagina]

The only OS support for SSE(x) is saving/restoring the registers while doing a context switch.

Actually, yes, Intel does create these randomly.

AMD and Intel have cross-licensing deals that handle the instructions that each company creates... these deals go way back to the mists of x86 time. So, for AMD to implement SSEn there is no legal problem. Ditto for the reverse. Except, the "problem" is that Intel w/80% of the market can pretty much dictate what instructions will survive in the market -- with the big exception of x86-64, and potentially some of the new virtualization stuff.

Now, about releasing chips in a timely manner... the trick is Int

There is a diffrence. AMD has to pay to license Intel patents...

A source familiar with the deal said it is essentially similar to the last one, which calls for Intel to receive royalties from AMD. Intel has patents covering aspects of the x8

I think that's a misprint. It should be "AMD doesn't get to collect royalties from Intel for any patents Intel might adopt."

8 hyperthreading cores running 8 threads each, with each core having 2 ALUs and 1 FPU.

Processing power over cost makes this expensive. Besides, notice how they say "hyperthreading" and threads... this isn't the same as "real" cores. Try loading up those threads and you will watch single thread performance drop like a rock on the T2000. We have this Java app, opens up 1GB RAM and 96 threads of execution. A E240 was more than 1.5 times as fast with 4 cores than the loaded T2000.

First of all, there are true 8 cores on a T1 (Niagara) chip (T2000 is the server if memory serves me right). There are 4 threads per core, which make sure that the ALU's and FPU's are used to the full. Now, there was some problems with floating point operations and crypto operations because not every core possessed these functionalities. The Rock processor, with 16 "processing units" (4 cores, 4 processing units each), 16 FPU's and crypto-processors will set this right.

Note that these chips are created to d

That's 64 concurrent threads, 16 ALUs, and 8 FPUs. And probably only needs a 150- or 200-watt power supply. There's a reason why Sun is getting something like $20K per UltraSPARC T1000 or T2000 rack-mount systems and can't keep up with demand...

Um, if you're talking about T1000 and T2000, that's 32 concurrent threads, 8 ALUs and 1 FPU. And the T1000 and T2000 start at $3995 and $9995, respectively. And lead time isn't an
