AMD Portables Hardware Technology

AMD Reveals New Mobile Technologies 78

Posted by CowboyNeal
from the speedy-names-for-on-the-go dept.
MojoKid writes "AMD disclosed a few details today regarding their upcoming mobile platform technologies, codenamed 'Griffin' and 'Puma'. According to AMD, Griffin will be manufactured at 65nm and it will feature a new mobile optimized on-die Northbridge with a power optimized DDR2 memory controller, HyperTransport 3 connectivity, and larger L2 caches than current designs. The new memory controller should also extend battery life thanks to new power saving features, that allow the controller to operate on a separate power plane and at a lower voltage than the execution cores."

        AMD badly needed to compete with Intel in the mobile computing market, and the Puma platform should get them some design wins, which would hopefully fuel a price war between the Puma and Santa Rosa platforms. At the risk of sounding cliched, the ultimate winner would be the customer. Unfortunately, despite AMD's efforts, I still think that AMD would be a marginal player in the mobile segment for some time to come, and would mainly competing with Intel C2Ds on price. I have yet to see AMD make compelling chips and platform designs for low power and ultra low-power laptops, for example. I would love to see it happen though, as this is one area where Intel is plainly getting away with overpricing their chips and platform solutions.

        What surprises me is why AMD is not putting in more efforts in making better mobile chips and platforms, when this is the one segment that is truly growing at a compounded rate. Heck, Centrino (and P-M) was the one and only reason that Intel managed to make a profit in the inglorious P4 days. One clear use case that I see is in corporations transitioning from desktops to laptops is simply "work-life balance". With the crazy hours that people are working nowadays, and the fact that broadband has become affordable, this will be the one carrot that more and more companies will dangle to keep their employees reasonably happy. Furthermore, as computers become commodities, people will increasingly look at differentiators such as mobility, ease of use, and connectivity instead of flexibility which was the desktop's forte. The only way in which this can truly happen though is if laptop prices start matching desktops in price and to some extent, in performance. In fact, performance is increasingly becoming irrelevant as most dual-cores and quad-cores are overkill for most users, even your so-called "power" users. Except for some niche areas like CAD or image processing, I have yet to see users complain because they are bottlenecked by their processor. Most users do get bottlenecked by their RAM or battery life (in case of laptops) though.

          The reason AMD has had a hard time competing is because they're a bit late in fabrication processes. Note that the above article mentioned the new chipsets will be made with 65nm fabrication. The Core 2 Duo is also 65nm, whereas older AMD processors were (I believe) 80nm.

          At 65nm, transistors can be placed much closer together, allowing for less signal degradation through the chip, so it can run reliably at lower power.

          The reason AMD's behind is because each fabrication plant costs a ton to make.

      Having merged with ATI, AMD now has all the IP it needs to do such a device. AMD in fact has a so-called "Fusion" development program [] to do just that. The Silicon on Insulator (SOI) process technology that AMD (unlike Intel) uses for CPUs has low leakage and is well suited for low-power devices. So in the short term, while the GPU and CPU are still separate, good reductions in power consumption can already be had by switching the production of the GPU/chipset of mobile devices to SOI.
      • AMD would need to expand their cleanroom space a lot to be able to fab GPUs on SOI as well as CPUs. If they had the space, this would be a good investment as it would let them make chipsets and GPUs using the older 90 nm 200 mm wafer equipment that no longer makes CPUs. Intel currently does this and it saves them money and gives them more control than using a third-party foundry like TSMC.

      Fusion will be the FIRST generation of CPU and GPU on the same chip, due out in 2008 I believe. PC on a chip implies memory, sound, and the rest though, so I wouldn't expect a "True PC-on-a-chip" until 2010 at the earliest. One chip with one or two gigs of memory, video, and sound on it would get pretty hot, so cooling it would be a bit of a problem.

    The CPU manufacturers seem to be focussed quite well on keeping their CPUs and motherboard chipsets within reasonable power limits, and this latest announcement by AMD is very promising. The situation is not quite so rosy in the 3D graphics chipset arena, as the review of the Radeon HD 2900 XT a few days ago highlighted ... The Tech Report had to upgrade their PC's PSU to 750W to achieve stability.

    That's "not good", to put it mildly. If you extrapolate the power consumptions of graphics cards over the last decade or more into the future, it rapidly takes us into the realms of impossibility, except for those interested in Freon cooling and running their own power station in the back garden.

    Something's got to change, and it has to be rather fundamental. Just decreasing die feature sizes has held back the rate of power consumption increases considerably, but that regular improvement is already factored in to this very bad upward curve we're on. We need something as dramatic as the change from MOS to CMOS was back in the day, which dropped consumption by orders of magnitude. If something like that doesn't happen, we're in big trouble.

    AMD's work on decreasing power consumption is great (and so is Intel's), but please focus your ex-ATI team's efforts on reducing the power guzzling on *graphics*. That's where the major problem for the future lies at the moment.

        hmm, rather tempted to edit the wikipedia entry to talk about the origins of the puma myth... Probably work the Incans into it somewhere. Now shall I make them protectors, or antagonistic creatures? *think think think*

      Well, we are talking about a platform, which is very much like a combination of different parts put together by magic. Chimera, Sphinx, Manticore, the list goes on for good code names for a project that involves multiple elements.

      I would like to see AMD work on audio technology as something to add. I still miss the old days of NVIDIA's Soundstorm.

      "Griffin"? "Puma"? Sounds like someone has a taste for mythological animals.
      Or someone watched too much Family Guy.
      Buy AMD laptops! How dare you disobey me? You will bow to me!

    As long as the advertisements don't include weight (and adapter weight if possible) and battery life in their commercials, it might not be worth it to go for the ultra-compatible arena. Here in the Netherlands at least they even put in commercials for ultra-thins without noting the weight and the battery life, even if these figures are more than decent. The difference seems to be made by a 80 or 100 GB HDD, which I don't care about for a bit.
  • There are a couple of additional technologies in development at this time as well. Code-named "Pea" and "Tear", they are set to be released at the same time as "Griffin".
  • long as Puma Man [] doesn't fall into the picture in any way, I'm happy.
  • and yet Intel is going to put their 65nm chips on the market in a few months. Does anybody else see the problem here?

      I think you mean 45nm for Intel.

      Yes, AMD is far behind Intel in manufacturing prowess... as is just about everyone.
    • This is a product announcement for something that will be launched at 65nm, it is not the first 65nm product. You're probably thinking of 45nm, which yes Intel is well ahead of AMD on. It's always been this way, with AMD lagging 6-12 months behind in process technology. So no, no big problem that I see.
