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.

If there is one thing that Intel is good at, it is writing a really big check to go in a new direction right when absolutely needed. Intel has released press information on what should be expected from their presence at the International Solid-State Circuits Conference which is currently in progress until the 23rd. The headliner for Intel at this event is their Rosepoint System on a Chip (SoC) which looks to lower power consumption by rethinking the RF transceiver and including it on the die itself. While the research has been underway for over a decade at this point, pressure from ARM has pushed Intel to, once again, throw money at R&D until their problems go away.
Intel could have easily trolled us all and have named this SoC "Centrino".
Almost ten years ago, AMD had Intel in a very difficult position. Intel fought to keep clock-rates high until AMD changed their numbering scheme to give proper credit to their higher performance-per-clock components. Intel dominated, legally or otherwise, the lower end market with their Celeron line of processors.
AMD responded with series of well-timed attacks against Intel. AMD jabbed Intel in the face and punched them in the gut with the release of the Sempron processor line nearby filing for anti-trust against Intel to allow them to more easily sell their processors in mainstream PCs.
At around this time, Intel decided to entirely pivot their product direction and made plans to take their Netburst architecture behind the shed. AMD has yet to recover from the tidal wave which the Core architectures crashed upon them.
Intel wishes to stop assaulting your battery indicator.
With the surge of ARM processors that have been fundamentally designed for lower power consumption than Intel’s x86-based competition, things look bleak for the expanding mobile market. Leave it to Intel to, once again, simply cut a gigantic check.
Intel is in the process of cutting power wherever possible in their mobile offerings. To remain competitive with ARM, Intel is not above outside-the-box solutions including the integration of more power-hungry components directly into the main processor. Similar to NVIDIA’s recent integration of touchscreen hardware into their Tegra 3 SoC, Intel will push the traditionally very power-hungry Wi-Fi transceivers into the SoC and supposedly eliminate all analog portions of the component in the process.
I am not too knowledgeable about Wi-Fi transceivers so I am not entirely sure how big of a jump Intel has made in their development, but it appears to be very significant. Intel is said to discuss this technology more closely during their talk on Tuesday morning titled, “A 20dBm 2.4GHz Digital Outphasing Transmitter for WLAN Application in 32nm CMOS.”
This paper is about a WiFi-compliant (802.11g/n) transmitter using Intel’s 32nm process and techniques leveraging Intel transistors to achieve record performance (power consumption per transmitted data better than state-of-the art). These techniques are expected to yield even better results when moved to Intel’s 22nm process and beyond.
What we do know is that the Rosepoint SoC will be manufactured at 32nm and is allegedly quite easy to scale down to smaller processes when necessary. Intel has also stated that while only Wi-Fi is currently supported, other frequencies including cellular bands could be developed in the future.
We will need to wait until later to see how this will affect the real world products, but either way -- this certainly is a testament to how much change a dollar can be broken into.
