For some time now we have been working towards a upgrade replacement for the microNVR. We need to increase it's video processing capability and its storage, while retaining the same general low power consumption and size.
roadmap. The Atom processor family has basically gone without an upgrade since 2009, while Intel focused its resources on building their Mobile Phone System Platforms, they let the Atom family languish. And in the Core product line there really were no viable options presented either. Most of their chips started at 25 watts or about 10x the power consumption of the Atom.
The Z550 Atom that we use in the microNVR runs at 2GHz and is a single core processor with two threads. The GMA500 GPU is capable of encoding about 30fps of 1080p video into H.264 streams. If you have 3 two megapixel cameras running at 10fps each, and are encoding the video or transcoding it for transmission, then you have pretty much consumed all of the capacity of the processor and GPU.

I have no idea where they got their power number.
The Atom is 1/10 the power of the Fusion.
So we waited, and waited, and waited. Finally Intel released a low power 3rd generation i3/i5/i7 processor family. The really good news is that these processors have Quick Sync technology built into them as part of the HD Graphics 4000 GPU. Quick Sync accelerates both encode and decode of H.264 (for applications that are designed to use it).
So we were excited to take a look. There is a lot of supporting documentation regarding the performance that Quick Sync brings to H.264. We expect that it will mean about 3x performance over previous generations of Intel Core processors. Or about 98fps of 1080p H.264 transcode with almost any member of the i3/i5/i7 3rd generation family (Ivy Bridge). However, running at 17W means that our system will consume somewhere around 23W versus the 10W that we consume today with the Atom system. This much power means twice as many solar panels, twice as many batteries, etc.
Then we got some even better news that Intel was going to release a new Atom processor in the second quarter of 2013 and that this new Atom (Bay Trail) would have Quick Sync in it and have the same HD 4000 GPU. Great, this is the CPU we want...well don't get too excited...
CPU World reported that Bay Trail was going to be delayed until mid 2014. This would have been a 3W chip that had all of the performance we wanted in the exact package size we need. But who knows when or if this will get released.
So we are going to punt. This probably means building a system for release in the next quarter based on the low power i3 or i7 processor. The system will be a little bit bigger and take more power. Then when the new low power Bay Trail comes out, we will jump back to that.
Unless Intel jumps around some more. Keep your fingers crossed.
