![]() 在低功耗计算领域,被Intel寄予厚望的Atom遭到了耕耘该市场数年之久的VIA的强力回击,65nm Nano对45nm Atom的战争已经打响.
目前他们已有的产品分别为VIA Nano L2100 (1.8GHz)和Intel Atom 230 (1.6GHz),这两位主攻手将承担第一场性能大战,PC Perspective 与 Hot Hardware已经给出了他们的性能评测数据,目前看来从性能上,VIA更占优势,在能耗上,Atom又更胜一筹一起来看吧!
VIA Nano
Intel Atom
VIA Nano Reference Platform
For testing and evaluating the VIA Nano platform the companyprovided us with a mini-ITX motherboard from a reference design - thisexact product isn't going to be on sale though partners will offerproducts very similar to it.
Themini-ITX platform has officially been adopted by Intel with the Atomproducts meaning that the VIA-created standard should actually become astandard now -- good news for all. For those that haven't seen amini-ITX motherboard yet you'll be scratching your head at seeing sucha compressed design. There are two DDR2 DIMM slots, four SATAchannels, one IDE connection and a single PCI Express x16 slot forgraphics or other add-in cards.
Onthe back of the reference board are a CompactFlash connection (for somesolid-state storage action) and a mini PCI slot as well. These wouldbe GREAT features to have on a retail board as well - I imagine bootingoff of an 8GB high-speed CF drive and using a standard drive forstorage.
Theexternal connections on the VIA reference board include the standardPS/2 connections, USB ports, serial output, dual NICs and VGA output touse in conjunction with the integrated S3 graphics core on the northbridge. There are audio connections as well on the right hand sidethat support up to 6-channels of output.
Hereyou can see the VIA 82375 south bridge under a passive heatsink, fourSATA channels on the motherboard that all support RAID and the singlePCI Express x16 slot that gives the VIA Nano platform such an edge overIntel's Atom for real world user applications. Without a PCIe slot onthe Atom motherboards, OEMs and users are forced to use the inferiorintegrated Intel IGP or a PCI graphics board, really limiting thepossibilities of getting top performance out of the Atom architecture.
VIA's reference design supports up to 4GB of DDR2-667 MHz memory though the controller is just single channel.
Theonly power connection on the VIA Nano motherboard is a 20-pin ATX powerconnector - don't worry your 24-pin power supply connections will workjust fine though.
Underthat single large heatsink with the fan on it lies the VIA CN896 northbridge chip and the VIA Nano processor; in our case the CPU is the Nano L2100 which operates at 1.8 GHz on an 800 MHz front-side bus with a max TDP of 25 watts.
Thenorth bridge handles all the PCI/PCIe and memory controller functionsand also sports the VIA Chrome9 HC IGP that supports DX9 features. Nothing to scream about, but it turns out to be faster than Intel'ssolution.

Intel Atom D945G Platform Forcomparison testing to our VIA Nano reference platform we got our handson an Intel D945GCLF motherboard with processor package.
![]()
You can find this exact retail package for sale on our pricing engine for just about $75- not a bad deal from just the amount of functionality you get insidethe box. Just like the VIA board, the Atom processor is soldered andpermanently affixed.

TheIntel D945GCLF is the same form factor as the VIA Nano referenceplatform: mini-ITX. This board design looks to be much simpler atfirst glance and that is in fact the case as we investigate a bitfurther into the design.

Theonly expansion slot that the Intel Atom motherboard offers is a PCIslot - any graphics expansion you plan to do will have to be relegatedto this older interface. This is really VIA's best selling point -they are allowing their platform to be completely open but Intel isONLY ALLOWING their boards and board partners to ship with PCI slots.

TheIntel board only has a single DIMM slot supporting up to 2GB ofDDR2-667 memory. The ATX power connector is again a 20-pin rather than24-pin but will still fit with 24-pin PSUs. There is a single IDEconnection and two SATA channels for your storage connectivity.
![]()
Hereyou can see the processor heatsink is incredibly small and passive onlyand is dwarfed by the chipset heatsink above it. Notice also that theIntel board requires you to use a secondary 4-pin power connection inaddition to the standard ATX power connector.
![]()
Theexternal connections on the board are similar to those seen on the VIANano reference board - PS/2, USB 2.0, serial, parallel, a single 10/100NIC, 6-channel audio outputs and a VGA output.
![]()
Removingthe heatsink reveals the full array of Intel chips - the Atom processorat the top, 945G north bridge in the middle and the Intel ICH7-M southbridge at the bottom. It is interesting to see how much more coolingthe 945G chipset requires compared to the Atom processor.
