Power Consumption & Noise

The move from the original Atom platform to Pine Trail dropped power considerably. The old Intel 945G chipset pulled more power than two dual-core Atom CPUs put together. The on-die GPU and NM10 Express chipset fixed that problem.

NVIDIA’s Next Generation ION platform increases power consumption over Pine Trail (and the original ION) because you’re adding a discrete GPU on top of the existing power budget of the platform. Thankfully it’s not a very power hungry GPU.

Power Consumption: NG-ION vs. ION
  Zotac ZBOX HD-ID11 (NG-ION) Zotac ZBOX HD-ND02 (ION1)
Idle 21.7W 19.7W
Load (Playing 1080p H.264) 27.0W 23.4W

Idle power is still in the low 20s and under load we saw the Zotac ZBOX HD-ID11 peak at around 27W. It’s a few watts more than the old ION.

There's a single heatsink + fan that's used to cool the CPU, GPU and NM10 Express chipset. At idle it's barely audible right next to the machine and unnoticeable from across the room. The problem is that the dual core Atom D510 can put out a decent amount of heat under full load. After a lot of testing the fan spun up to 6500 RPM and then noise is another issue entirely. I measured 55 dB(A) an inch away from the unit with the fan running at 6500 RPM. A foot away we're still at 50dB(A).

This situation only appears to happen with the CPU running at its max clock speed however. The XBMC Live image I installed doesn't seem to let the Atom cores underclock themselves to 600MHz when idle which results in heat building up very quickly. I suspect this is simply an issue of not having the right driver installed to enable EIST.

Under Windows 7, being used as a HTPC, the fan always remained quiet. But if you are constantly doing a lot of CPU intensive stuff, expect the system to get considerably louder.

    and switch wifi to usb

    While this looks pretty kick ass I'm looking forward to the Amd version. I'm curious how well the Neo processor with 3200 will do against the Aton with Ion2.

    I too would like to see products from amd and/or via to compete here.
    I'm tired of "the intel show" 24/7

    I wouldn't pay $100 for that ion thing

    As the Zotac NM10-B-E motherboard is shipping with HDMI and the Intel NM10 chipset, the Broadcom Crystal media solution is a viable build your own HTPC strategy that operates on fewer watts. I would have liked a side by side comparison.

    Does this or any ION2 nettop use Optimus??? I am looking for a small D510 system to run headless and would be willing to buy an ION2 system strictly for the resale value if it uses Optimus to switch off that power hungry GPU. I am sill waiting on the Shuttle XS35 to show up as it is fanless.

    The comments in the article about manufacturers not wanting to reclaim PCIe lanes from WiFi and GbE don't sound so convincing. For example, they could easily integrate WiFi via internal USB or an Ethernet bridge.

    Heck, if nVidia wanted to make a real symbiotic chipset to go with this they could actually engineer a GbE/WiFi chip that uses multiple internal USB ports to achieve enough bandwidth. And by "enough" I mean "somewhat more than 100mbps but less than 1,000mbps." Users can't often maximize GbE because they need a GbE switch for full duplex and, assuming a max-speed file copy, a destination drive which can write as fast as the source can send. I doubt many users really need GbE over 10/100 Fast Ethernet/802.11n.

    Also, what happened to all the rumors of an OC'd PCIe bus for ION2?

    As for Zotac's design, I'd much prefer a larger, cooler, quieter design than this, especially if it is going in a home theater. If it would still be super-small, why not give it a proportionally huge HSF? The LEAST they could do is give it metallic housing and throw a heat pipe on it (even just one side).

    The latency guys, the latency.
  • KaarlisK - Sunday, May 9, 2010 - link

    Besides which, the NM10 chipset only has 1 USB2 controller, so no increase in bandwidth from ganging USB ports.

    I enjoyed the article and this looks like a viable option for my next HTPC. However, I didn't see anything addressing the signal issues most people experienced with the initial version. Can you comment on that?

    Thanks.

    How come we don't see any of the ULV CPUs in form factors like this? I cannot imagine it'd be too difficult to stick in a Celeron SU2300, or a Pentium SU4100, or one of the ULV C2S chips. There's super netbooks that are thinner than these nettops that use these ULV chips. I can't imagine that designing a little beefier cooling system in the same Zotac chassis or into the Acer Revo chassis would be overly difficult. It may add a little to the price, but the trade off in performance might be worth it.
