超微(Advanced Micro Devices)發(fā)布了兩款全新的28nm移動(dòng)x86處理器，均采用全新基于ARM架構(gòu)的安全模塊，其中一個(gè)是功耗僅2W的平板SoC。這些芯片將在明年7月前出貨，采用它的筆記本電腦和平板電腦“性能/功耗比”將提升一倍，AMD方面表示。
這兩款芯片包兩到四個(gè)AMD Puma x86核心， GCN級(jí)Radeon圖形內(nèi)核和ARM Cortex-A5安全模塊，支持ARM基于硬件的TrustZone安全功能。筆記本用SoC“Beema”有不同的版本，運(yùn)行功耗在10-25W，而平板芯片“Mullins”功耗約2W，AMD表示。
新芯片的使用都定位在Windows 8.1的筆記本電腦和平板電腦，支持該操作系統(tǒng)的新“InstantGo”快速喚醒時(shí)間功能。AMD首席技術(shù)官馬克·佩珀馬斯特(Mark Papermaster)在AMD年度開(kāi)發(fā)者大會(huì)上發(fā)表主題演講時(shí)，說(shuō)到該SoC “圖形方面的表現(xiàn)將優(yōu)于競(jìng)爭(zhēng)對(duì)手，總計(jì)算性能在無(wú)風(fēng)扇平板電腦、2合1筆記本和超極本中也是佼佼者?！?
這種新的芯片本身不支持谷歌Android或Chrome OS環(huán)境的平板電腦和筆記本電腦?！拔覀?cè)贏MD AppZone上有一個(gè)仿真解決方案，現(xiàn)在正與BlueStacks開(kāi)展這方面的合作，我們計(jì)劃到CES上宣布下一級(jí)的合作伙伴關(guān)系?！?AMD發(fā)言人表示。
著兩款新芯片是在AMD發(fā)布Kaveri SoC后發(fā)布的，Kaveri是其第一款支持“HSA基金會(huì)技術(shù)”的SoC，讓CPU和GPU模塊實(shí)現(xiàn)資源共享，大大地提高了效率。不過(guò)這兩個(gè)新芯片可不支持HSA功能。

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.
