AnandTech Peeks At The Athlon 4

tupac writes: "AnandTech has posted a story about AMD's new Athlon 4 processor and also included some information about Silicon on Insulator transistors in their article. SOI technology has been used by IBM in recent history and AMD will begin using it in 2002." This is the chip which has been known for a while as Palomino. Reader Diabolus points to the same article, saying "the big news is a 20% reduction in power consumption, and that they'll be using the exact same chip for servers, workstations, desktops and even notebooks. The article details exactly what is new compared with the Tbird."

    That's what you get for trying to respond in one sentence...aiming at the general populace...

    Increase in speed will use up more power unless you do changes to your chip (and other cicuits). This is important since there is a finite amount of heat that can be absorbed and dissipated from a chip. The reason for the power consumption is that there is a certain current needed to carge and discharge the capacitance of a CMOS. The heat comes from the fact that Power = Voltage(drop) * Current, so to increase the frequency you need to do one or more of the following.
    • Decrease the capacitance of the CMOS (e.g. make the transistor smaller)
    • Lower the voltage
    • Reduce other impedance or resistance (e.g. decrease interconnect length and use better conductors copper/gold)

    Usually all of this is done to each new CPU. Lowering the voltage does have a negative impact on performance but it is still required to enable higher frequencies due to heat factors. Actually some of the lower voltage performance hit is offset by other improvements (i.e. less power loss in interconnects)

    Intel understands it because Intel caused it. Intel's adverstising over the past 2+ years has focused on two things. First, they make MHz seem equivalent to horsepower. Second, they make vague claims that Intel processors make "the internet" faster. AMD played Intel's MHz game for a while and did a damn good job beating the big boys at their own game. Now they're not playing anymore. They seem to be focusing now on creating good processors at a reasonable price.

    I don't think it's true that people are buying Intel's MHz = performance ploy, or the whoel GHZ PC hype for that matter.

    The evidence is:

    a) P4 is hardly selling at all

    b) The whole PC market is stagnent. Most people have 2/3/4/500MHz or whatever PCs that do all they need, and see no need buy a new GHz PC

    Really, outside of DVD ripping, there are few reasons for a *typical* person to need this much speed - certainly not enough reason for them to want to shell out $1000 or more for a new PC.

      From http://www.tomshardware.com/cpu/01q2/010514/palomi no-09.html:

      "AMD chose two notebook chipsets for Mobile Athlon 4 and Mobile Duron. It's ALi's MaGiK1 and VIA's KT133A chipset. The MAGiK1 is able to run with PC100/133 SDRAM as well as PC1600/2100 DDR SDRAM, but so far we weren't too convinced of its performance in desktop systems. VIA's KT133A is a good performer, but it does not come with DDR-SDRAM support."

      Because of supposed performance problems no vendors have announced any laptops w/ ALi's chipset, so at this point in time the mobile Athlon, which is certainly *my* choice of a dream portable processor, is not being offered with DDR.

      I really wish today we were seeing a mobile AMD 760 or SiS 735 DDR PC-2100 solution, but these chipsets do not have mobile versions.

      Ideally we would be ogling the Athlon 4 on the nVidia "Crush" chipset. As I recall, Crush uses a 128 bit memory bus to DDR memory that allows for a hideous amount of low-latency bandwidth, something like 3.6 GB per second.

      But I digress, it is enough to have a mobile Athlon solution that absolutely wipes the floor with anything offered by their x86 competitor. :) Good for AMD, today is another proud day for them. :)

      And I am sorry if anyone misread my initial comment, DDR compatibility is a function of the chipset, not the processor. Hopefully with the other two explanations I have posted here this has been clarified for one and all. I am off to bed, this was a bitch of a day. ;)
