Initially, AMDs low-power line will include 10 different processors, which consume either 35 watts or 65 watts across its Sempron, Athlon 64 and dual-core Athlon 64 x2 lines. AMDs desktop chips normally use about 90 watts. The chip makers 35-watt line will include several single-core Sempron models, ranging from a model 3000+ to a model 3400+ as well as a single-core Athlon 64 3500+ and the dual-core Athlon 64 X2 3800+.The chips will range in price from $101 for the Sempron 3000+ to $364 for the X2 3800+ chip, AMD said.AMD will also offer an all-dual-core line of 65-watt chips. The chips, which parallel its Athlon 64 X2 line, include X2 models that range from the 3800+ to a 4800+ and list for between $323 and $671, the chip maker said. The low-power chips will be based on AMDs latest chip circuitry, often dubbed ref F, meaning they use its new socket AM2 and have the capability of working with DDR2 (Double Data Rate 2 SDRAM). Thus the low-power chips wont arrive before AMDs unveiling of its standard-wattage rev F/AM2 desktop chips, which are due in the near future, AMD officials said. Using the chips, manufacturers "will be able to develop more small form factor [PCs] that give them the opportunity to build system for emerging types of usage models," said David Schwarzbach, division marketing manager for desktop products at AMD in Austin, Texas. "All of our energy-efficient models will have the same performance characteristics [as standard AMD chips]. Theres no trade-off in performance." AMD believes the chips will help make it easier for PC makers to create products such as small desktops and blade computers for businesses. The 35-watt chip line, meanwhile, should allow for more ultra-small form factor desktopsthe best example of which is Apple Computers Mac Minito be designed with cheaper desktop parts, versus using notebook processors, which tend to cost and dont always deliver as much performance. But AMD isnt alone in seeing a trend toward differing desktop designs in the figure. Its larger rival Intel has been showing off small form factor desktop designs independent of the launch of its Intel vPro brand for business desktops, recently. Is smaller better for enterprise PCs?

The chip makers maneuvers come as desktop minitowers, the form taken by most PCs at the moment, are expected to give way to so-called small form factor desktopswhich are roughly half the size of a standard minitowerin as soon as three years in some markets, according to a recent forecast by researcher IDC. Small form factor machines will gain favor with corporations, and consumers to a lesser extent, IDC predicts, because the more diminutive machines take up less space and generally produce less heat and noise than minitowers, in part by using more power-efficient processors. As part of the shift, so-called thin clients will also see a jump among corporate customers, IDC has predicted. Thin clients, once seen strictly as terminals that operate off a central server, are themselves diversifying into diskless desktops, blade desktops and even virtual desktops, which use virtualization to host numerous desktop instances on a back-end server, transmitting them to each workers screen. AMD will find its rival, Intel, going after many of the same markets. Intel, whose executives have said it is working a line of thin-client processors, plans to deliver a new line of low-power chips for desktops and notebooks this summer. Intels Core 2 Duo desktop chip, a dual-core processor for desktops due in July thats otherwise known as Conroe, will use 65 watts of power, Intel has said. Its Core 2 Duo notebook chip, otherwise known as Merom and due in August, will use about 30 watts, the chip maker has said. Intel will place Core 2 Duo chips into its vPro platform for corporate desktops. A vPro Professional version of the platform will include the Core 2 Duo, along with new supporting chips and enhanced security or manageability features for businesses. Intel is pitching vPro as the base for mainstream business desktops for the next year. Merom chips, meanwhile, could show up in ultra small desktops. For its part, AMDs client transformation initiative, lead by Seyer, is expected to come to the surface sometime later this year. "Yes, the thinnest-possible client may be one of the many usage scenarios that we cater to with thisour [transformation] road map. But theres a spectrum between your PDA, the thinnest thing, and a PC blade in a datacenter or even a server that is in a datacenter," he said. "You will see us introduce whatever were going to introduce based on this client re-invention. Its not going to be its a dual-core, secure, single vendor. Were going to stand back and look at this overall perspective, this range of clients." Check out eWEEK.coms for the latest news in desktop and notebook computing.
