AMD Launches 'Kaveri' APUs for Business Notebooks
The new AMD Pro A-series chips following the introduction earlier this year of the Kaveri offerings for desktops.Advanced Micro Devices is bringing the capabilities of its "Kaveri" desktop processors to notebooks with the unveiling of its AMD Pro A-series offerings. AMD officials introduced the new accelerated processing units (APUs) June 4 at the Computex 2014 show in Taiwan, saying new features will enable the company to more closely compete with larger rival Intel in the business laptop market. Like the desktop-focused A-Series "Kaveri" APUs launched in January, the new mobile chips come with the company's latest "Steamroller" CPU core and it Graphics Core Next (GCN) architecture, including Radeon R7 graphics technology. The chips feature up to 12 cores—four compute cores and eight GPUs—and support for UltraHD 4K resolution applications; they also include AMD's TrueAudio technology for improved sound in systems. In addition, the Pro A-series chips will be the first to bring the Heterogeneous System Architecture (HSA), which is designed to make it easier to move workloads between the CPU and GPU. Before, workloads were sent to the CPU, which then decided whether to move them to the GPU. With HSA, workloads immediately go to whichever element will work best, which AMD officials have said improves the performance and efficiency of the systems.
Through HSA, the CPU and GPU "become more than just a collection of IP on one piece of silicon," Kevin Lansing, senior director of mobility solutions for AMD's Client Business Unit, said during a press conference held before Computex opened. The CPU and GPU become "equal citizens."
