While it is utterly inconceivable that Josh might have missed something in his look at Carrizo, that hasn't stopped certain Canadians from talking about Gila County, Arizona.  AMD's upcoming processor launch is a little more interesting than just another Phenom II launch, especially for those worried about power consumption.  With Adaptive Voltage and Frequency Scaling the new Excavator based chips will run very well at the sub-15W per core pair range which is perfect for POS, airplane entertainment and even in casinos.  The GPU portion speaks to those usage scenarios though you can't expect an R9 295 at that wattage.  Check out Hardware Canucks' coverage right here.

"AMD has been working hard on their mobile Carrizo architecture and they're now releasing some details about these Excavator architecture-equipped next generation APUs."

AMD Details Carrizo Further

Some months back AMD introduced us to their “Carrizo” product.  Details were slim, but we learned that this would be another 28 nm part that has improved power efficiency over its predecessor.  It would be based on the new “Excavator” core that will be the final implementation of the Bulldozer architecture.  The graphics will be based on the latest iteration of the GCN architecture as well.  Carrizo would be a true SOC in that it integrates the southbridge controller.  The final piece of information that we received was that it would be interchangeable with the Carrizo-L SOC, which is a extremely low power APU based on the Puma+ cores.

A few months later we were invited by AMD to their CES meeting rooms to see early Carrizo samples in action.  These products were running a variety of applications very smoothly, but we were not informed of speeds and actual power draw.  All that we knew is that Carrizo was working and able to run pretty significant workloads like high quality 4K video playback.  Details were yet again very scarce other than the expected timeline of release, the TDP ratings of these future parts, and how it was going to be a significant jump in energy efficiency over the previous Kaveri based APUs.

AMD is presenting more information on Carrizo at the ISSCC 2015 conference.  This information dives a little deeper into how AMD has made the APU smaller, more power efficient, and faster overall than the previous 15 watt to 35 watt APUs based on Kaveri.  AMD claims that they have a product that will increase power efficiency in a way not ever seen before for the company.  This is particularly important considering that Carrizo is still a 28 nm product.
