Hasta La Gadget!

ARM CEO Warren East already has a tendency to be more than a bit outspoken on the future of computing, and he just escalated the war of words with an assault on the industry’s sacred cow: Moore’s Law. After some prompting by MIT Technology Review during a chat, East argued that power efficiency is “actually what matters,” whether it’s a phone or a server farm. Making ever more complex and power-hungry processors to obey Moore’s Law just limits how many chips you can fit in a given space, he said. Not that the executive is about to accept Intel’s position that ARM isn’t meant for performance, as he saw the architecture scaling to high speeds whenever there was a large enough power supply to back it up. East’s talk is a bit long on theory and short on practice as of today — a Samsung Chromebook isn’t going to make Gordon Moore have second thoughts — but it’s food for thought in an era where ARM is growing fast, and even Microsoft isn’t convinced that speed rules everything.

The Apple rumor-mill is cyclical, and one tale refuses to die: Apple ousting Intel from its MacBooks, and replacing x86 chips with ARM-based alternatives. The story surfaces periodically, just as it has done today, with titters of increasing “confidence” within Apple’s engineering teams that Intel will be eventually ditched in favor of the company’s own A-series SoCs as currently found within the iPad and iPhone. Not today, so the whispers go, but eventually, and what’s most interesting is that we’re likely already seeing the signs of the transition in Apple’s newest models.

Apple has arguably pushed tablet processors as far as they need to go, at least for today’s market. There’s a sense that the Apple A6X chipset in the latest, fourth-generation iPad with Retina display was a near-meaningless improvement on the A6 its predecessor sported; far more important was the change from old-style Dock Connector to new Lightning port. Sure, the newest iPad is faster in benchmarks, but in day to day use there’s hardly a noticeable difference.

Those benchmarks give some hints, however, as to where ARM chips might make sense on the desktop. The iPad 4 did particularly well in SunSpider, a browser-based test of JavaScript performance that gives a good indication of how fast the web experience will be. Considering most of us live online when we’re using our computers, that’s an increasingly important metric.

The iPad 4 scored under 880ms in our SunSpider testing (the lower the number, the better), making it one of the fastest tablets around in that particular benchmark. Now, admittedly, a current-gen MacBook Pro is capable of scores a quarter of that. But, more importantly, the iPad 4 can run for more than ten hours of active use delivering its level of performance, on a 43 Whr battery. Inside the new 13-inch MacBook Pro with Retina, in contrast, Apple finds room for a 74 Whr pack.

“Intel may make a fast processor but it’s behind the curve in efficiency”

The allure of an ARM-based MacBook, then, is the combination of that growing performance and the power frugality of the chips that deliver it. Intel may make a fast processor, but it’s behind the curve when it comes to efficiency compared to ARM; the company’s struggles with Atom in the mobile market are evidence of that. And, while there’ll always be a cadre of performance-demanding Mac users, the regular cohort with more everyday needs might be more than wiling to sacrifice a little top-end grunt for the longevity to make it through a transatlantic flight with plenty of juice to spare.

In the end, though, Apple is notoriously self-reliant. The company has bought or invested in specialists in chip components, displays, aluminum casing production, optically-laminated displays, component assembly, and more. Anything, in short, that contributes to Apple’s supply chain or its competitive advantage in the market place (or preferably both). Sometimes the fruits of those investments go relatively unused for years, at least as far as the public can see; Apple’s perpetual and exclusive license to use Liquidmetal in its range – something so far mostly limited to a SIM-removal tool – is a good example of that.

We’ve also seen how it won’t shy from distancing itself from vendors when they either won’t toe the line or let the company down. NVIDIA’s time in the doghouse after the faulty MacBook GPU saga is good evidence of that, while AMD has long been tipped as attempting to curry Apple’s favor but never quite delivering the goods in internal testing.

If Apple can rid itself of reliance on another third party – and further extend the distance between its range and Windows-based PCs, blurring the lines of direct comparison – then it will undoubtedly jump at that chance. It’s unlikely to be shy in flexing its checkbook to do so, either, betting on long-term investment over short-term gains.

Apple, if time has taught us anything, will do what’s best for Apple: that means it demands the biggest advantage from those it works with, and isn’t afraid of taking a hit if it needs to change in order to achieve greater returns. In the past, Intel has given it early access to new processors, as well as the collaborative spoils of Thunderbolt ahead of PC rivals. If Intel can’t meet the grade on the sort of processors Apple sees as pivotal to its vision of future computing, however, all that shared history will be for naught. As far as Apple goes, it’s the Cupertino way or the highway.

AMD’s advantage these days most often rests in datacenters that thrive on the chip designer’s love of many-core processors, so it was almost surprising that the company brought its Piledriver architecture to the mainstream before turning to the server room. It’s closing that gap now that the Opteron 6300 is here. The sequel to the 6200 fits into the same sockets and consumes the same energy as its ancestor, but speeds ahead through Piledriver’s newer layout and instructions — if you believe AMD, as much as 24 percent faster in one performance test, 40 percent in performance per watt and (naturally) a better deal for the money than Intel’s Xeon. Whether that’s true or just marketing bluster, there’s a wide spread of chips that range from a quad-core, 3.5GHz example to a 16-core, 2.8GHz beast for massively parallel tasks. Cray, Dell, HP and others plan to boost their servers before long, although the surest proof of the 6300’s success from our perspective may be that everything in the bacrkoom runs just as smoothly as it did yesterday.

Intel’s taking its 48-core processor and applying it to a field beyond academia: the world of mobile electronics. The company this morning announced intentions to slip the 48-core bad boy into future tablets and smartphones (emphasis on future), with CTO Justin Rattner saying the mobile implementation could arrive “much sooner” than the 10-year window predicted by researchers.

Aside from the thrilling world of linear algebra and fluid dynamics that the chipset is currently used for, Intel says it could offload processor-intensive functions across several cores, effectively speeding up various functions (say, video streaming). The availability of so many cores also means faster multitasking possibilities than the current dual- or quad-core offerings in modern smartphones and tablets — just imagine a world where two Angry Birds games can run simultaneously in the background without affecting the paradoxical game of Tiny Wings you decided to play instead. Hey, we understand — it’s just a better bird game. No big. Sadly, few software developers are crafting their wares (warez?) to take advantage of multi-core processing as is, so it’s gonna take more than just the existence of Intel’s 48-core chip to make its vision a reality.

Now that AMD’s fresh new FX processors based on the Piledriver architecture are out in the wild, the specialist hardware sites have seen fit to benchmark the top-lining FX-8350. Overall, the group feels that AMD has at least closed the gap a bit on Intel’s Core juggernaut with a much better FX offering this time around, but overall the desktop CPU landscape remains unchanged — with Intel still firmly at the top of the heap. Compared to its last-gen Bulldozer chips, “in every way, today’s FX-8350 is better,” according to Tom’s Hardware: cheaper, up to 15 percent faster and more energy efficient. Still, while the new CPUs represent AMD’s desktop high-end, they only stack up against Intel’s mid-range Core i5 family, and even against that line-up they only edge ahead in heavily threaded testing. But if you “look beyond those specific (multithreaded) applications, Intel can pull away with a significant lead” due to its superior design, says Anantech. As for power consumption, unfortunately “the FX-8350 isn’t even the same class of product as the Ivy Bridge Core i5 processors on this front,” claims The Tech Report.

Despite all that, Hot Hardware still sees several niches that AMD could fill with the new chips, as they’ll provide “an easy upgrade path for existing AMD owners and more flexibility for overclocking, due to its unlocked multipliers.” That means if you already have a Socket-AM3+ motherboard, you’ll be able to do a cheap upgrade by swapping in the new CPU, and punching up the clock cycles might close the performance gap enjoyed by the Core i5. Finally, AMD also saw fit to bring the new chip in at a “very attractive” $195 by Hexus‘ reckoning, a much lower price than an earlier leak suggested. Despite that, however, the site says that AMD’s flagship FX processor still “cannot tick as many desirable checkboxes as the competing Intel Core i5 chips.” Feel free to scope all the sources below to make your own conclusions.
