ARM to Intel: it’s not just about the transistor# PDA - 掌中宝

"Fewer transistors means lower power," he countered. "so RISC is inherently
lower power."
有人只看到intel在能耗上的进步,不看其付出的代价。那些trick早晚会成包袱。

While not exactly unanticipated, Intel's unveiling of its 22nm manufacturing
process, featuring a new kind of transistor, seems to have got many
commentators rather bullish about Intel's prospects in the mobile device
market, where it's currently a virtual bystander.
In a curious piece of timing, market researcher IDC chose today to announce
it will be including ARM architecture in its PC market forecasts from now on
, and kicked things off by announcing it expects 13 percent of PCs to
running chips based on ARM architecture by 2015. Seeing as there are
currently no PCs running ARM chips, and IDC doesn't count tablets as PCs
right now, that's quite a prediction.
So with all this news and speculation flying around, we thought it was time
to have a chat with ARM CMO Ian Drew, who was himself a long-time Intel
employee before joining ARM in 2005. While we didn't expect him to have any
inside information on Intel - far from it - we wanted to know what the
significance of Intel's announcement was to ARM.
"Intel has always innovated through process improvement," said Drew, "But it
's not just about the transistor. You have to also consider the architecture
, SoC design, the broader ecosystem, and so on."
So Drew isn't contesting the significance of Intel's technological
breakthrough. But while a smaller manufacturing process undoubtedly confers
power/performance benefits, so does the micro-architecture, the efficiency
of the whole SoC, software optimisation, and so on.
We put it to Drew that Intel had said it was a ‘misconception' that ARM's
architecture was somehow intrinsically more power-efficient than Intel's. "
Fewer transistors means lower power," he countered. "so RISC is inherently
lower power." Drew also pointed out that ARM has already announced test
chips at 22 and 20nm already, with foundry partners TSMC and GlobalFoundries
also working on those processes, and that IBM is already working on 14nm.
Moving on to the IDC report, Drew took it with a pinch of salt. "If it
happens we'll be very happy, but forecasts are always wrong in some shape or
form," he said. "The ARM business model is not to favour one form over
another." In other words, whether you call it a PC, a tablet or a smartbook,
if it's got ARM IP in it then ARM's happy.
The implications for the low power market were the main theme of the Q&A
after Intel's announcement yesterday. While Intel itself didn't focus on
mobile devices much in the formal presentation, it clearly feels 22nm plus
shiny new transistor can be a real difference-maker in bid to take on ARM in
mobile devices.
But we can't fault Drew's assertion that it will take more than just
technological innovation for Intel to convince the mobile device ecosystem
to move away from ARM - just ask MIPS. The biggest obstacle Intel has to
overcome is momentum. The likes of Qualcomm, TI and NVIDIA already have
relationships with mobile OEMs, and the trend is for the bigger device-
makers to license ARM's technology in order to design their own chips.
So Intel probably has to not only match, but significantly beat ARM's
technology offering before mobile OEMs will even consider moving away from
ARM. And with the likes of Apple, Samsung, and maybe more already making
their own SoC's the number of potential customers may be shrinking.
