AMD Carrizo SoC Revealed; Emphasis on Energy Efficiency

February 26, 2015, By Sanjeev Ramachandran

It’s often tough in the modern day computing world to find a balance between performance and battery life. Things have turned out to be a matter of prioritization.

When we were up for the news that AMD is revealing their new SoC, we all thought the tech giants to follow the path of Intel by laying added emphasis on its power management. And yes, that wasn’t a fool’s thought.

At the International Solid State Circuits Conference (ISSCC), AMD has revealed their upcoming A-series Accelerated Processing Unit (APU), named Carrizo, which aims to better the power management among notebooks and low-power desktops.


But as it seems, it hasn’t entirely wiped out the performance scales for boosting power either. Their new SoC is the first to have adopted the Heterogeneous System Architecture, which assures an effective performance despite the compromises it has made for power management.

AMD’s Carrizo will be arriving with the 64-bit Excavator CPU cores, which is claimed to be 5% more powerful than the former ‘Kaveri’ processor, with around 29% improvement in transistors keeping the same die size.

Fitting on-board will be the new generation AMD Radeon GPU, whose combined effort with the Excavator is expected to bring in fine improvements in the overall CPU and Graphics performance.

The shift in performance does appear to be marginal, which certainly is not the case with the power management offered by this new SoC. AMD’s implementation tuning has led for a massive reduction in the size and power requirement of Carrizo.

Upto 40 percent reduction has been claimed to be achieved by the CPU alone, while the GPU cores has now hiked its power efficiency by around 20%. The company says that their SoC will ‘deliver the largest generational performance-per-watt gain ever for a mainstream AMD APU’.

Besides the power-efficient features, Carrizo also hosts an on-chip dedicated H.265 video decode that ensures the smooth streaming of UHD videos, one which cannot be left behind when stepping into the 4K era.

It is expected that Carrizo will be heading for the notebooks during the second quarter of this year, close to the slated release of Intel’s Broadwell processors.
