What's Next in CPU Land after Itanium? 589
"I work for a major research organization. Of late a lot of the normal big computer companies have been visiting and preaching the gospel of
Itanium. My question to them, and to the assembled masses here at Slashdot is what happens next when Itanium is real? My world view is that Itanium based systems will become commodity products very quickly after good silicon is available in reasonable volume. At that point, why should one spend $8-10k for that hardware from the likes of HP, Compaq, Dell and others when one can build it for $2k (or even less)? In other words, has Intel finally done in most of their customers by obliterating all the other CPU choices (except IBM Power4 [& friends G4, et al] and AMD Hammer) and turned the remainder of the marketplace into raw commodity goods? Lest you defend the other CPUs... Sparc is dead,
Sun doesn't have the money (more than US$1B we'll guess) to do another round. PA-RISC is done, as HP has
given away the architecture group. MIPS lacks
funding (and perhaps even the idea people at this point). Alpha is
gone too (also because of the heavy investment problem no doubt). Most other CPUs don't have an installed base that makes any difference, especially in the high end computing world. So what's next? I don't like the single track future that Intel has just because it is a single track!"
Itanium vs. Hammer vs. All Others. (Score:4, Interesting)
I'm not too worried about Itaniums, and I don't see them becoming prevalent for quite a while. While the Pentium II, III, and IV moved through the marketplace fairly rapidly they all offered compatibility at some level. If I recall correctly 32 bit programs that are not rewritten for 64 bit run SLOWER on the Itanium than they do the equivalent Pentium line.
In essence consider this: it's like a brand new operating system attempting to break into the monopoly that Microsoft has. (Parallels drawn out of necessity.) While it may be better, faster, superior in every way it doesn't have 20+ years of legacy code behind it - and that will end up being what drags it down.
Only time will tell. Remember the Pentium Pros..

So here's the question: how do you keep competition alive when an initial investment costs in the billions of dollars. For any company less than Intel sized, a single bad product cycle spells complete doom. That's no kind of market to be in.
Also, wasn't this inevitable. There are a few Beowulf jokes being posted, but that's really what's going on. Increasingly high performance tasks (Google, render farms etc. etc. etc.) are using massive arrays of low-power CPUs. It costs a lot of money to develop big iron chips, and if people aren't buying them then there's no point in investing that much money.
What I'm worried about are the isolated markets that still require massively powerful, low processor number architectures. Not everything splits into nice Distributed.net packages.

Now don't get me wrong - 64-bit filesystems are great, and necessary - being limited to 2GB or 4GB files is terrible. But no 64-bit CPU is necessary for that kind of thing, the filesystem just has to be written as 64-bit (which is easier said than done, and could easily sacrifice backwards-compatibility with various API's, but I digress...).
That being said - Intel might very well be moving down the wrong path - the Itanium is a huge, expensive, hot, completely new chip. Even Intel is hedging its bets [theregister.co.uk] on whether or not Itanium will take off - and AMD is poised to eat Intel's lunch with their new Hammer design [com.com].
Who knows, perhaps all CPU's from now on will be compatible with x86 IA32, and innovation will be in the various processing units that sit behind the instruction-set decoder. Take a look at AMD or Transmeta for examples of that, already.

"It's pretty well understood that Itanium will not provide leadership x86 performance. That's Hammer's great hope, in fact. AMD's strategy depends on Intel mistakenly abdicating its x86 throne leaving Hammer and its descendants the heirs apparent to a software kingdom.
Would Intel so cavalierly jeopardize its legacy? Not on your life. To no one's great surprise, Intel is rumored to be developing something that will give future Pentium processors--not IA-64 processors--a performance kick. In a perverse reversal of roles, Intel may actually be following AMD's lead in 64-bit x86 extensions. A "Hammer killer" technology, code-named Yamhill, may appear in chips late next year, about the time Hammer makes its debut. It's suggested that Intel's forthcoming Prescott processor will be based on Pentium 4, but with Yamhill 64-bit extensions that coincidentally mimic Hammer's. (Prescott is also rumored to be built on a 0.09 micron process and implement HyperThreading.)
Naturally, the very existence of Yamhill, if it exists at all, is a diplomatically touchy subject at Intel HQ. The company doesn't want to undermine its outward confidence in Itanium and IA-64, but neither can it afford the possibility of ceding x86 dominance to a competitor. Besides, whether they appear in future Pentium derivatives or not, Intel's 64-bit extensions could appear in future IA-64 processors instead. New IA-64 features plus competitive x86 performance--now that's a compelling product."

I think a lot of people are too overconfident that Itanium is going to be successful, let alone quickly. It is going to require a lot of changes to software in order to take advantage of it because it isn't just a 64 bit x86, it is a whole new architecture, one more closely related to HP PA-RISC than x86. It also may not do a very good job of running existing 32 bit code, which could slow down its acceptance, particularly in desktop systems. The last time Intel made a big push (with the i432) to create a whole new non-x86 processor family, it was less than successful. Although to be fair, the i432 was a radically different proposition and the Itanium with its more proven PA-RISC roots looks a lot more sound.
AMD's Hammer architecture, on the other hand, is more conservative, being a x86 family processor extended to 64 bit. It should require less modifications to existing software to take advantage of it, although an argument could be made that it won't have as much advantage to take having more legacy issues with the aging x86 architecture. It also may perform a lot better on existing 32 bit code than Itanium. And if AMD's track history holds true, it will probably be significantly less expensive than the Itanium.
A lot of whether it is Intel or AMD that paves the way for 64 bit mainstream CPUs will probably have to do with which of them is the first one that offers a price attractive product that runs existing 32 bit software well while being marketable as a 64 bit chip. Unfortunately for AMD, the marketable part is, as always going to be tough. While AMD has been hugely successful in "white box" sales where customers can choose their CPU, they've had a much more difficult time penetrating the big name PC markets, particularly in higher end systems. This despite the fact that in many cases an Athlon or Duron would offer a better performance than a PIII or P4 at a better price.
Itanium will take YEARS to commoditize... (Score:2, Interesting)
Until there is breakthrough brought on by computing speed, we will see a stall in computer upgrading as we have seen in the past.
I expect we will see more things like the Imac (very cool computers), before we see a press for new computers for speed.
The two things I think will create the next level breakthrough.
Real Time CGI imaging at Toystory/Mosters INC/FF, level of quality. We can probably predict precisely WHEN that will be possible by mapping the development speed of 3d hardware, memory, software breakthroughs, and polygon density to date, and where the predictable bottlenecks will appear. (My suspicion is that we are 5-8 years away).
The other breakthrough which I think would do it, and right now it is very difficult to predict when it will happen, but I suspect that adoption would be pretty rapid, is real time voice interaction that is 5 9's accurate. This is likely to appear after a certain speed level of computers, and a breakthrough understanding/algorithm for speech recognition.
However, I suspect the AMD x86-64 solution may be adopted much faster than the Itanium solution. Likely there is an app out there that may have a large enough niche to require 64 bit apps, and the rest of the apps on the computer would be 32 bit. I suspect that the app will be imaging or video related, and that will create an adoption around the AMD solution, before the Itanium moves out of the server market to the desktop market where it will be commoditized.

The UltraSPARC for workstations has always kinda been a niche market. For the simple reason, that you can get an Intel box with far more hardware options and software support and for far less money.
However, in the server market (which I doubt the submitter has ever had any experience in) is a different story. For the most part, hardware support is irrelevant if it does what you want it to do. Which in most cases is just be some type of Internet server.. be it oracle databases or web servers or whatever. People that run critical servers and need the UltraSPARCs stability and Sun's support (or this can go for some other alt. arch. like IBM and an AS400) almost always do buy something other than Intel for their mission critical stuff.
Anyway, my whole point is, just because you don't use it in your workstations (or your webserv0r on your dsl line) doesn't mean its dead. Workstations and Servers are and hopefully always will be very very different to actual companies that need a different level of service from their servers.

Regarding supercomputing, you are quite correct in that there is little incentive to develop new vector supercomputers, taking into account increasing costs of design and fabbing the cpu:s. Cray:s upcoming SV2 seems to be an exception, though. Also keep in mind that most supercomputers, like the Cray T3E and the IBM SP, are just commodity cpu:s connected with a bad-ass proprietary interconnect. So essentially, they are just beowulf clusters with a superfast and low-latency interconnect. They are programmed through MPI, the same thing used for beowulf.
While there are few scientifically interesting applications which require essentially no communication between the nodes, like seti@home and distributed.net (if you want to do something scientifically useful with your spare cycles, check out folding@home), most get by with a quite modest amount of communication between the nodes.

The trick is inter-related logic complexity. To my understanding the existing GPUs have no issues with backward compatability (so much of the x86 overhead is avoided), the core itself is pipelined and modular, so the complexity is spread out across the whole chip (independent teams can work on their own components with little concern for sistern components, whereas every ounce of performance is being squeezed out of x86's which require complete coordination). Further, graphics acceleration is simply the application of graphical algorithms into silicon. While I'm not quite sure which algorithms there are, the possibilities are endless. Imagine a fast-fourier transform implemented as a SIMD floating point instruction. You create an array of floating point logic units, and interconnect them. The floating point unit is pretty much a common-off-the-shelf design, so the only real logic you apply is the interconnectivity.
