  I recongnize that some people may totally write VIA off in this market, but don't overlook the fact that an improved shipping model of this board could at least cause Intel to rethink its Atom strategy. I really wanted an Atom system for a while, but then I realized for the same price as the setup I wanted, an i3/gigabyte mini itx system would be about the same price. A stripped down Atom board from Intel wouldn't be worthwhile at all, even if it is $80. In the business and mobile spaces, Atoms make a good argument. Its just a stale argument. AMD and VIA bringing more options to the market can't be called a bad thing. My hope is not just that VIA doesn't fail entirely, but that I have lots of interesting options in the near future.

  Intel definitely could use a chip midway between the current atom and CULV product lines. The dual core atoms don't really help much; yeah they're better at decoding video that the GPU doesn't support, but the atoms general performance problems are single threaded in nature.
  
  Clocking the chip up to ~2.5ghz would probably help a good bit there but would probably blow the power budget out of the water.
  
  Intel's stated that atom will remain in order for at least the first 4-5 years, so we shouldn't expect this to change. With intel primarily aiming atom at Arm's market share something that adds a lot of complexity to the chip is probably out of the question anyway.
  
  A more efficient memory controller connection might help. The current implementation is on die FSB so there's definite room to improve here. How much this would help is something of an open question though. Outside of memory bound benchmarks the ~2x latency difference between the directly connected and on die FSB controllers in lga 1366 vs 1156 i7's wasn't very large; but as an in order CPU with a tiny cache memory latency is a bigger impact on the atoms performance, although this is partially balanced by it having a much lower load on the memory sub system due to is generally slow performance This might be the easiest place for Intel to speed things up though.
  
  Alternatively the runtime gap between atom and CULV isn't that large, it might be possible to push it down into the current atoms power envelope even at atom drops into the higher end part of Arms territory.

  I remember reading an article last year from digit life that you can get some pretty massive performance gains on a Nano just by tricking your windows install into thinking its Intel. Seens the code handed to the nano is pretty shoddy even next to AMD.
  
  Anand, to get a true representation of the nano's performance I'm afraid you will have to do a cpu-z hack.

  Why is there a "ATI Radeon HD 5450" in the power consumption graphs? That makes no sense. Where is the Athlon X2 3250e?
  
  Should compare the processor in this system, the Neo X2, if different:

  "Despite the typical omg-thisisntATI/NVIDIA error that some games always throw,"
  NT 4's CPUID code was full of such problems:

  Even more recently, 64-bit Windows has a hardcoded list of CPU vendors it will run on, and will BSoD with UNSUPPORTED_PROCESSOR on any other vendor. An update had to be released to add CentaurHauls to the list.
  Is there an option in the BIOS to fake a GenuineIntel CPU vendor?

  A fair and competitive marketplace!

  The complete Via CPU story - long before they named it Nano - is essentially a story of not delivering.
  All these jesaya and what not platforms one could never really by them.
  And yes Nano looks nice, the single core one didn't look to bad a year ago. But where is anything build with it that one can buy?
  
  More competition? Great! but please make it to market.
  
  Maybe now is the time Nvidia buys VIA.

  Sorry, but my old Epia C7 sucks only 25W from the socket, and its fast enough for the job.

  When VIA comes out with a product, I really want to like it, and I want them to succeed. I actually got a cheapie notebook for a parent with a C7-M processor that worked well for quite some time until their needs grew. That said, here are my two issues.
  
  "I should add that although the Chrome 520 GPU does support H.264 acceleration, I couldn't get it working with the driver drop I had on my test platform. CPU utilization would be low but I still dropped frames. I suspect this is a driver or software compatibility issue which I do expect VIA to rectify before the platform ships."
  
  VIA (or should I say S3) has had many times where a graphics driver with bugs or compatibility issues that have delayed a product's potential after its release until it is no longer competitive with newer offerings. If the bugs aren't fixed at initial product release (I hope they are, but from experience...) that would be a huge strike against this.
  
  "The DC Nano platform I tested is built on an old 65nm manufacturing process at TSMC. As a result, power consumption isn't that great. Also note that VIA doesn't do any power gating, so idle power ends up being very similar to Clarkdale"
  
  If the Nano had power consumption that beat AMD but lost to Intel, I think we'd all be excited. Heck, if it matched AMD but with lower heat output, I think I still would be. However, we're looking at a product that cannot beat a Core i3 in performance, that equals it in power consumption. I think not doing power gating is a huge mistake here.
  
  I hope the released product has the driver issue fixed, and I hope VIA can consolidate their architecture (i.e., turn a 2-core Nano into an SoC or at least a partial SoC) for power savings, lower expense, and maybe performance improvement. That said, I'll also believe it when I see it.
