SAN JOSE, Calif. – Advanced Micro Devices announced two new 28nm mobile x86 processors using a new ARM-based security block, including a 2W tablet SoC. The chips, shipping before July, will double the performance/watt of the company's prior notebook and tablet offerings, it said.
Both chips pack two to four AMD Puma x86 cores, GCN-class Radeon graphics cores and an ARM Cortex-A5 security block supporting ARM's TrustZone hardware-backed security. The Beema notebook SoC comes in versions running at 10-25W, while the Mullins tablet chip draws about 2W, AMD said.
The chips target Windows 8.1 notebooks and tablets, supporting the OS's new InstantGo fast wake-time feature. The SoCs "will outperform the competition in graphics and total compute performance in fanless tablets, 2-in-1s and ultrathin notebooks," said Mark Papermaster, AMD's chief technology officer in a keynote at AMD's annual developer conference.
The new chips do not natively support Google's Android or Chrome OS environment for tablets and notebooks. "We have an emulated solution on the AMD AppZone now as part of our relationship with BlueStacks, and we plan to have news at CES that takes the partnership to the next level," said an AMD spokesman.
The new chips were announced two days after AMD announced Kaveri, its first SoC supporting the HSA Foundation technologies for letting CPU and GPU blocks on an SoC share resources for greater efficiency. The two new chips do not support the HSA features.
