AMD Announces 65-nm Chips, Touts Power Savings 234

Posted by kdawson from the smaller-and-cooler dept.
Several readers wrote in about AMD's entry into the 65-nm manufacturing generation. The company introduced four chips to be manufactured with 65-nm process in the first quarter of 2007 to replace existing 90-nm chips in their lineup. AMD is playing up the power economy of its line, claiming that even its existing 90-nm parts consume less than 50% the power of Intel's Core 2 Duo, averaged over a typical day's usage, while the new 65-nm chips will be even stingier with power. Next stop, 45-nm. The article says that AMD has a goal of catching up within 18 months to Intel's lead on the way to 45-nm technology.

        AMD's argument goes like this: modern desktop and notebook processors constantly scale up and down between full speed and an idle state, which AMD has branded "Cool 'n' Quiet". At a given time, pushed to full load by an application, AMD's chips run hotter and consume more power. But across a typical computing day - where a user might check his email or surf the Web - the processor idles more often then not. At idle, AMD's 90-nm Athlon 64 X2 consumes 7.5 watts.

          Of course but some of AMDs changes in the last year have made a HUGE difference on the notebook front. DDR2 consumes much less power than DDR1, catching them up to intel as far as that goes. Then theres their new 65nm proccess with much less power drawing parts. After notebooks start coming with flashmedia for most hard drive duties we should start to see smaller screens and ultra low power notebooks that last as long as cell phones when in use.

          I wouldn't measure power consumption on a laptop that way, for a few reasons:

          1) That would take into account the efficiency of the transformer, which doesn't impact battery life.
          2) Many laptops run in a high power/performance mode when plugged in.

      Why, because you think Intel are going to stand still while AMD move to 65nm? By the time AMD actually ship 65nm, Intel will be shipping 45nm. And I call bullshit on AMD's power claims, at least until independent reviews have verified them. Intel's new core specifically designed for power efficiency and manufactured with a 65nm process uses more power than a 90nm has-been from AMD? Excuse me for feeling skeptical.

            I remember a test in the German C't magazine where complete computers were tested. Everything being equal except mainboard and CPU. The CPUs were AMD Athlon 64 vs. Intel Core2Duo

            Under load, the Core2Duo machines used a bit less power. Idling, the AMDs were better. The overall differences were pretty small compared to the total power consumption, so I'd disregard them for a typical desktop that does NOT run 24/7.

            And BTW, avoid the old Pentium 4/Pentium D. Those are really inferior.

      Not really screwed, especially if they fail to catch up but do narrow the gap. AMD has always been behind Intel in terms of process technology. AMD has gotten ahead on some specific process tech, like copper interconnect and SOI, but in terms of overall process shrinkage and quality of process, Intel has always been ahead. AMD has been more behind in the past, but also a lot closer, sometimes only months behind Intel. Basically, they are familiar with this situation.

      65nm was a particularly bad node for AMD in terms of Intel's lead. Their plan for 45nm seems to be shaping up better with Fab 36, so I expect them to be closer though probably not caught up.

      AMD has consistently been a step behind Intel in the die-shrinking competition. The fact that AMD's chips run as cool as or cooler than their equal-performing Intel counterparts even at the larger process is a credit to good engineering.

      Of course, since Intel will also be moving forward over the next 18 months, they might end up still in the lead. Making a huge turnaround like they did (from Netburst to Core) in such a short time is remarkable. Creating an architecture and setting up the process and designing a generation of chips takes a looooong time. Kudos to Intel for that. Now the ball is in AMD's court, and they have to respond.

      At the high end, of course, Intel rules. What about processors that normal people buy?

      I was recently looking at a Core2Duo review, and noticed something interesting. At each brand's bottom end (E6300 vs. X2 3800), Intel outperformed AMD. The problem in my mind, however, is that Intel's bottom-end starts at a higher price point than AMD's. Very smart marketing move by Intel. However, If you match the processors price-to-price, the E6300 matches up against the X2 4200 (both currently around $180), and there is relatively little performance difference. In other words, the price/performance metric really isn't in anyone's favor.

      Another smart (but a little slimy) marketing move Intel has made is in the power dissipation numbers. AMD quotes their CPU's maximum dissipation, and Intel quotes a power figure for some arbitrary (under 100%) CPU load. Intel looks good here....until you actually measure a system's power draw at the outlet, and find that again, there's not that much difference. This may (and probably will) drastically change as AMD's 65nm parts get out, but we'll have to wait and see.
      • In other words, the price/performance metric really isn't in anyone's favor.

        That just isn't true. There are 4 consumer Core 2 Duo models. For every one, you cannot buy an AMD CPU for the same price or cheaper that won't be beaten in most workloads, and the closest performing AMD CPU will have much lower performance per watt.

        Don't get me started on the mobile and 2-8 core server market, Intel has completely decimated AMD's offerings there for now.

I got sick of buying new hardware just to open the same document because the O/S or new Office suite was bloated/full of shit/required way more horsepower just to do the same task. No Vista for me. I'll stay will XP and Linux on my (older) machines. And if MS forces people to go Vista, I'll go Linux or BSD.

      Features or efficiency. That's just how it goes. If you want software that does more nifty shit, you have to be willing to throw more horsepower at it. Lynx uses less memory, disk, etc than Firefox, however you certainly aren't going to see me switching. It's not like there is some magic programmers could use but don't to write fast, feature rich software.

      Now maybe you long for the days of spartan computing, maybe you want to do nothing but scroll text really fast. That's fine, there's stuff out there to accommodate you. However that's not what most of us want. I want a feature rich system, I want my computer to be everything, do everything. Well for that I need hardware, and I'm willing to pay for it.

      It would be like trying to compare frame rates between Ultima 1 and ES4: Oblivion. When you get down to it, Ultima 1 probably has a frame rate as fast or faster than Oblivion. Ultima 1 wouldn't have any trouble running at 30fps or more, even on 286 hardware. Oblivion can run under 30fps, even on an 8800GTX. However you are dealing with a totally different level of graphics. Ultima 1 was made to run in CGA which is 2D, 2-bit (4 colour), 320x200. Oblivion is full 3D with amazingly high geometry, 128-bit FP colour, 2560x1600 with anti-aliasing. Despite the speed being around the same, there is a difference.

      While games are teh most pronounced difference, it's still there with other apps. Comparing Office to an old text mode Wordperfect app is meaningless. Ok, maybe for what you do you don't notice any difference, but many of us do. As a simple example, take a highly accurate, learning, in-line spell checker. I love that feature. Well, guess what? That takes resources. You couldn't do that on a really old computer, it just lacks the resources.

      So if you are happy with what you have now, great, stick with it, but don't get mad that people want to find ways to use the new power. I do not buy a new graphics card to get higher and higher frame rates, 60fps is enough thanks that's all my screen does. I buy it for more an more features, at the same framerate. Likewise with processing in my computer. Everything is plenty fast now, my computer responds near instantaneously for normal tasks. So what I want is for my computer to do more. I want it capable of doing more complex things. In 1996 my computer played little postage-stamp sized videos, and used nearly 100% CPU to do it. Now it plays fullscreen HD videos and uses nearly 100% CPU (well ok, of one of the cores) to do it. I'm not pissed that it hasn't changed, I'm pleased with the increase in quality, the increase in features.

Computers are going to go under, they are going to become *embedded* in everything with no expectaions of mainenance to them at all and installed in harsh environments. They either work or they fail after decades of use (or preferably, never), and then you replace them.

    Reliability is CORE, and to achieve it, computers are going to have to abandon all cruches and become purely solid state devices entombed in indestructible plastic modules.
