ARM Cortex-A15 cores are coming to smart phones and tablets in late 2012 or early 2013, packing up to 16 cores clocked at up to 2.5 GHz. Early designs will likely only have two to four cores.   (Source: The Gadget Guy)

Release the Cortex A15!

James Bruce, the U.S. mobile segment manager at ARM Holdings (ARMH), announced this week another important step in ARM's plans to try to further dethrone the veteran x86 and become the world's most used computer architecture.

I. Superpower Smartphones Almost Here

Starting late next year or in early 2013, Mr. Bruce announced this week, smartphones, tablets, and possibly laptops using ARM's new Cortex A15 core will go on sale.  Initially the chips will be dual-core designs, but the architecture supports up to 16 cores.  The cores can be clocked at up to 2.5GHz.

Expect top ARM chipmakers NVIDIA Corp (NVDA), Samsung Electronics Co. Ltd. (005390) (and its partner Intrinsity, Inc.), Texas Instruments Inc. (TXN), and Qualcomm Inc. (QCOM) to all be readying Cortex A15 designs to ship next year.  NVIDIA and Texas Instruments recently became the first Cortex A15 licensees, indicating their design efforts have already started.

All ARM cores of a specific architecture share a certain amount of commonality, but the actual design and performance can vary significantly between licensees.

Current cutting-edge smart phones and tablets like the Motorola Xoom, the new Galaxy Tab 8.9/10.1-inch models, and the LG G-Slate use Cortex A9 processors.  Cortex A9 can only support up to four cores and clock speeds of up to 2 GHz, maximum.

But aside from bumping the core count and the speed, Cortex A15 delivers numerous architectural improvements that should bump power performance and increase the efficiency of parallel processing on mobile devices.

The Cortex A15 design was previously announced in September, but this was the first time concrete availability information has aired.

II.  What's Next?

Along side the architectural efforts of ARM Holdings and its corporate partners will be a series of die shrinks.  Intel Corp. (INTC) recently stated it was confident it would beat ARM in power consumption by 2013, by moving to the 22 nm transistor node.

But ARM Holding's Mr. Bruce says that Qualcomm is already moving to a 28-nm process and will soon be joined by the other licensees.  Intel currently is at the 45 nm node, for its latest Atom (Lincroft) mobile designs.

By 2013 ARM will likely be on the 22 nm node as well.

Mr. Bruce says that his company won't target the server market, which it calls a "legacy" market, till 2014.  Many are looking forward to ARM servers, as they would offer a very power efficient, presumably affordable RISC alternative to x86 designs.  And with Microsoft Corp. (MSFT) announcing that it would support ARM with Windows 8, the possibility that future version of Windows Server will support ARM seems strong.

In the meantime Mr. Bruce says that ARM Holdings and its partners will continue to focus on mobile devices like smart phones and tablets.  He says he is excited about new "convertible" designs like the Motorola Atrix 4G, which transform a smartphone into an impromptu Android netbook.

He also says that future ARM-powered devices will be capable of streaming video over Bluetooth to your television.  He states, "The interesting thing in the smartphone space is the small screen coming to the big screen."

Because of price. PC is cheaper than a high end smartphone with those super duper quad ARM cores with bazillion gigahertz, plus PC does not require super expensive data_and_voice plan like a high end smartphone does, plus PC uses DSL with _stable_ and uncapped (300 gigabytes a month is not a cap really) bandwidth which is way way waaayyy better than piece of sh1t molasses slow mobile "network" you get on a smartphone (or a fast nice network but with tiny data cap for a lot of money or even without a cap for an insane price like couple of hundreds a month combined). Open architecture PCs will always beat proprietary closed system smartphones price wise, performance wise and network bandwidth wise. And no smartphone ever ever will get any close to a $200 cheap AMD GPU framerate/resolution wise. You can't change laws of physics buddy, so stop your senseless mobile propaganda :P PCs and smartphones have very different niches, and one cannot replace the other completely and never will be able to. Because of the laws of physics and economics. Got it?
gaming rigs become impractical and expensive
Stupidest bullsh1t of today :))) Gaming rigs become smaller, quieter and CHEAPER every year, the old huge noisy box that you'd need to build 5 years ago to be able to run Darksiders with tiny resolution and low framerate turned into a quiet little cheapo box with some cheapo AMD 6790 inside that can run all your games with highest framerate no problem. The days of super expensive huge full tower gaming rigs are over, modern console ports like Crysis 2 work on cheapo middle end micro-ATX machines like charm. Your stupid bullsh1t about "expensive" "inefficient" etc etc gaming rigs is not even funny anymore.
