AMD发布X86/ARM架构混搭处理器，目标笔电和平板

超微(Advanced Micro Devices)发布了两款全新的28nm移动x86处理器，均采用全新基于ARM架构的安全模块，其中一个是功耗仅2W的平板SoC。这些芯片将在明年7月前出货，采用它的笔记本电脑和平板电脑“性能/功耗比”将提升一倍，AMD方面表示。 这两款芯片包两到四个AMD Puma x86核心， GCN级Radeon图形内核和ARM Cortex-A5安全模块，支持ARM基于硬件的TrustZone安全功能。笔记本用SoC“Beema”有不同的版本，运行功耗在10-25W，而平板芯片“Mullins”功耗约2W，AMD表示。 新芯片的使用都定位在Windows 8.1的笔记本电脑和平板电脑，支持该操作系统的新“InstantGo”快速唤醒时间功能。AMD首席技术官马克·佩珀马斯特(Mark Papermaster)在AMD年度开发者大会上发表主题演讲时，说到该SoC “图形方面的表现将优于竞争对手，总计算性能在无风扇平板电脑、2合1笔记本和超极本中也是佼佼者。” 这种新的芯片本身不支持谷歌Android或Chrome OS环境的平板电脑和笔记本电脑。“我们在AMD AppZone上有一个仿真解决方案，现在正与BlueStacks开展这方面的合作，我们计划到CES上宣布下一级的合作伙伴关系。” AMD发言人表示。 着两款新芯片是在AMD发布Kaveri SoC后发布的，Kaveri是其第一款支持“HSA基金会技术”的SoC，让CPU和GPU模块实现资源共享，大大地提高了效率。不过这两个新芯片可不支持HSA功能。 编译：Luffy Liu 参考英文原文：AMD Secures PC Notebooks, Tablets With ARM,by Rick Merritt

{pagination} AMD Secures PC Notebooks, Tablets With ARM Rick Merritt 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.
