Apple To Discuss HyperTransport For Future Macs

macrealist writes "CNET is reporting that Apple will discuss the use of HyperTransport in Macs at the Developer's conference. The interesting thing is that the article claims that Apple is not likely to use hypertransport to link the CPU to the memory, but instead to link chipsets together because IBM would have to 'to adapt it to the Power architecture.' But according to arstechnica, the 970 does have a frontside bus that operates at similar speeds to Hypertransport."

    does not necessarily need to be used throughout the system. I can see where they'd use it to connect the two processors in a dual chip computer but let the front-side bus be something different. Though it is interesting that they picked the name "Smeagol" for the OS revision that allows thee 970 to be compatible, because the whole idea behind HT is to allow all the chips to speak the same language so nothing has to be translated from chip to chip. "One bus to bind them" perhaps?

      Apple seriously needs to buy SGI.

      Seriously.

      Hear me out.

      The Origin family of computers is basically the coolest thing out there. It's getting a little long in the tooth--the node-to-node interconnect is only 3.6 GB/s which isn't awe-inspiring any more--but it's got serious coolness.

      IRIX is a great operating system, but it's also long in the tooth, and it's tied to MIPS processors.

      The Origin design transcends the CPU, however; behold the Itanium Origin, which SGI calls the Altix. (Yes, it's hideously ugly. I'm getting to that.)

      Basically Apple could buy SGI for a song right now. In the transaction, they'd get all of SGI's IP and sales contracts. They could continue operating SGI as an independent company to serve existing customers and customer bases--NASA, NOA, that sort of thing--but shut down everything that's not profitable. Like the nationwide sales channel, for example. What a cluster-fuck that is. Get existing big MIPS customers migrated over to Darwin on PowerPC or Darwin (Linux compatible) on Itanium (I see no good reason to keep going with Linux development) over the next five years or so.

      The Origin 350 gets PowerPC processors and Mac OS X Server and becomes the next-generation XServe. Four processors (or maybe even eight; PowerPC's are small and cool) in two rack units, scalable with external 3.6 GB/s high-speed interconnect up to 32 (or maybe 64) processors. No clustering required; that's a single system image for those who need or want it. Ideal price point for an entry-level four-processor system: ~$5,000. Maybe get really cool and do a two-processor system for ~$3,000. Get in bed with Oracle and Sybase (moreso, I mean) and get their stuff running better on PowerPC than it does on any other platform. (Are databases candiates for vector optimizations?) If it makes sense, get big applications like Oracle and Sybase and Web Objects and BLAST and so on running on Itanium 2 versions of the Origin 350-based Xserve. If it makes sense. Keep the PowerPC available throughout the product line, however, for compatibility with existing software.

      The Power Mac-based Xserve would remain as the lower-cost and non-scalable option.

      If the demand ever exists for it, which it might someday, Apple can put PowerPC's in the Origin 3900 family (the SN-2 family) and sell supercomputers that scale from 4 to 1,024 processors and up. If the demand exists.

      As for SGI's visualization systems, IR4 and IP, if it makes business sense, keep 'em around. If it doesn't, kill 'em.

      Fuel? Kill it unless it can pay for itself. Same with Octane2. Same with Chimera, the upcoming Origin 300-inspired workstation product.

      But the good news is that Apple would be able to take the truly cutting-edge work SGI has been basically pissing away, like GSN with ST for multi-gigabyte-per-second communication over TCP/IP and XFS/CXFS for high-performance direct-attach and fabric-attach storage and FailSafe for high availability and (1) continue developing them in a sort of skunkworks R&D environment, and (2) move them down to the servers and desktops as it becomes practical to do so.

      SGI has seriously got it goin on, but they've lost all momentum in the marketplace and need a hero. Apple has momentum in the marketplace and would benefit from a leg up on some cool advanced technologies. Also, Apple has assloads of cache and valuation to trade with.

      Please please please please please...

  3. Switch? by executebusiness.com · · Score: 5, Interesting

    I have been thinking of switching over to Apple, and now that many designers are coming up with cool products with OSX support, I am paying much more attention to Mac. I can remember back in the day when I first saw an Apple 2e, and I thought that it was so much better than my TI 99/4A, because of the games mostly. Oh and it had it's own monitor, and at the time I needed a TV for my TI. :)

    I like the idea that Mac develops the hardware and software together under one roof. I think following the process from all angles like that would make for a better product. It's a better philosophy than the Windows/PC mish-mash way of thinking, primarily because no person sees all ends of the production for PC, and you can bet that there are quality issues with computability under PC that just aren't there with Apple (or at least that is what one would expect). So looking at Hyper Transport, at this stage, I'm a tad leery of it because it didn't come from Apple. I'm worried that it might have some kind of negative impact on the technology.

    The necessary question is; is this going to be the next evolutionary step for Apple, or is it just an added hardware feature that is relatively minor?

  4. CHRP anyone? by ihatewinXP · · Score: 4, Interesting

    Heres to hoping that the Hypertransport consortium becomes to Apple what the CHRP spec always promised to do. Common specs + multiple vendors (apple, amd and who else?) = cheaper prices for everyone. From what I gathered the first area we will see the hypertransport spec will be in connecting the PCI bridge and various components like that - not processor to memory connections. But that said, it seems to me Apple is really jumping on the right bandwagon here, anything that moves the platform away from this starved processor pc133 ram shit is in my opinion A Very Good Thing.

    And yes i will be selling both my macs to get a ppc970 the day they come out.

  5. Re:What about upgrades? by Funksaw · · Score: 5, Interesting

    It's true - Macs are harder to upgrade the CPU than PCs. Everything else is fair game, but the CPU is expensive to upgrade. On the plus side, Macs retain their resale value for much longer. If you buy a top of the line Mac in year X, by the time you ebay it in year X+2, it'll probably pay for half of your new top-of-the-line mac. I'm trying to sell my laptop right now to buy a mac... because my Laptop is windows based, I can't get crap for it - even though it's only 8 months old. -- Funky.

  6. Why wouldn't Apple do it all themselves? by benwaggoner · · Score: 4, Interesting

    This is a non-rhetorical question.

    Why would Apple buy SGI instead of doing it all themselves? Like you say, in the long term, the OS and the current hardware and the sales organization would be punted. With the 970, Apple looks to be be developing the guts of a strong workstation/server technology on their own. Buying the customers and transitioning over might be possible, but would the (checks NASDAQ.com) $241M be worth it? Wait, $241M? That's all for all of SGI? Well then!

    A few things I could see Apple wanting out of SGI:

    Maya. Buying that and making it Mac only would be in keeping with all of Apple's purchases lately. Make a free rendering client for Xserve. It'd be neat

    The sales organization. Given what SGI is facing in the market place, that they're still around and showing some revenue suggestions SOMEONE is rising to the challenge there.

    Existing customer base. Buy the accounts. Make an IRIX compatibility layer for MacOS X.

    Engineers. Presumably they've still got some good folks there. Apple could certainly use all the talent they can get in UNIX code, hardware design, etcetera.

    I don't see much long term value in SGI's existing products if Apple bought them though, and Apple is certainly willing to give up market share on other platforms in order to make a package Mac-only.

    Still, given that the whole company is only $241M, it seems like there might be something worth cherry-picking there.

      Why would Apple buy SGI instead of doing it all themselves?

      Because the stuff I talked about is a shitload of incredibly complicated hardware design IP. Apple would need years and a whole new staff of scientists and engineers to build it themselves from scratch.

      With the 970, Apple looks to be be developing the guts of a strong workstation/server technology on their own.

      Chips do not a server make. How you gonna connect 1,024 of those 970's together? Hypertransport? Pff.

      Maya.

      Maybe, but AW is a wholly owned subsidiary. They might get spun off.

      The sales organization.

      A thousand times no. SGI's sales organization sucks. Their sales PEOPLE are okay, sometimes, but the organization sucks.

      Existing customer base.

      Yes. Although IRIX compatability for Darwin ain't gonna happen. Better to migrate those customers to PowerPC or Itanium.

      Engineers.

      Most of the truly great SGI folks fled a long time ago, with some notable exceptions. But yes, there are some good folks in Mt. View.

      I don't see much long term value in SGI's existing products

      The Origin architecture is the key to a mid-range scalable server. You've got your 2-p 1-U units, and you've got your 128-p racks. Not much in between but SGI's Origin 350. Sun? Yeah, if you wanna pay through the nose and end up with a system that can't scale. The great thing about the Origin 350 is that you buy one (4 processors) and start using it. You decide you need more oomph, so you buy another one (4 processors) and hook 'em together, and you've got 8 processors. No new software, no migration, just plug it in and go. (Reboot required.)

      Apple NEEDS this scalable technology to give them a compelling story in the midrange server market. Combine it with the power of UNIX (TOG's bitching notwithstanding) and the wonderment of Mac OS X Server and you've got yourself a product line.

      Apple is certainly willing to give up market share on other platforms in order to make a package Mac-only.

      Apple is INCREASING market share (or trying to, and succeeding in large part) by taking top-of-the-line UNIX products like Shake and making them Mac OS X-only. It's a good strategy.
