The new high performance, energy efficient processor from AMD has landed. During the International Solid State Circuits Conference AMD has released their new Accelerated Processing Unit (APU) name Carrizo, it uses an x86-based central processing core code named Excavator and next-generation Radeon graphics in a System-on-a-Chip (SoC) design.
This new line of processors is build for notebooks and low-power desktops. Carrizo is set to replace its predecessor “Kaveri”, both are 28-nanometer chips but AMD was able to get form Carrizo 29 percent more transistors, 3.1 billion, and still maintaining its size. It combines a number of Excavator low power cores and the results are pretty good. The Carrizo APU is built in a configuration that allows the GPU and CPU cores to share the entire platforms memory map, working together on the same blocks of data as they execute code allowing a more organized process between them, reducing the number of instructions required to complete tasks.
With the help of the new SoC design, AMD is expecting a drop in power consumption in the x86 cores by 40 percent but in the same time providing gains in CPU and graphics. As a result the battery life in notebooks and mobile devices is extended. The multimedia support includes the on-chip H.265 video decode, so true 4K resolution will be supported and the bandwidth requirement for video streams will be reduced.
The AMD Carrizo is using a new technology called adaptive voltage and frequency scaling. It involves the utilization of patented silicon speed capability sensors and voltage sensors besides the classic temperature and power sensors. This allows the APU to change and adapt its characteristics and behavior.
The new chip looks promising and in the second quarter of the year we should see it hit the market.
