ARM's latest design brings 64-bit processors to smartwatches
It's no longer hard to find 64-bit processors in smartphones. In smartwatches, though, they're still a rarity -- and ARM wants to change that with its new Cortex-A35 processor design. The architecture promises the most energy-efficient 64-bit mobile chips yet, sipping 32 percent less power than the mid-range A53 even as it outruns the Cortex-A7 it's meant to replace (6 to 40 percent faster). It's extremely scalable, too. You can build full-fledged quad-core chips for entry-level smartphones, but you can also strip things back to make tiny chips for watches and activity trackers.
ARM's latest processor design puts fast 4K graphics on your phone
You've probably heard no end of hype for 4K video on TVs and computers, and now it's about to invade your phone... at least, so long as ARM has its way. The company just took the wraps off of Cortex-A72, a processor reference design that promises a huge boost to computing power, especially when graphics come into play. Thanks to updates that include optimizations for an efficient 16-nanometer chipmaking process, 30 percent more memory performance and an 80 percent speedier graphics core (the Mali-T880), the A72 is about 3.5 times more powerful than ARM's earlier Cortex-A15. That's beefy enough to record 4K video at an extra-smooth 120 frames per second -- many current smartphones only manage 30FPS at best. You should get "console-class" gaming, too, and there's a promise of Google Now-style natural voice commands that don't depend on a distant server to interpret what you're saying.
NVIDIA explains why its 64-bit chip should be Android's speed champ
NVIDIA set out to claim the Android performance crown when it unveiled its 64-bit Tegra K1 processor at the start of the year, and it's now ready to explain why it expects to come out on top. The chip's two Project Denver cores will have an edge partly because they'll optimize code on the fly -- they'll break down big instructions into tiny, super-efficient functions that can be recycled as often as necessary. The company expects roughly twice the speed it would get from ordinary code, making the 64-bit K1 faster than you'd expect just by looking at the hardware. It should tout "significantly higher" performance than current four- and eight-core mobile CPUs, and run as well as some PC processors; be prepared for more Tegra-powered laptops and high-end tablets.
ARM's Cortex-A50 chips promise 3x performance of current superphones by 2014, throw in 64-bit for good measure
We knew this was coming, not least because someone let the cat out of the bag (or at least a paw) last night. Nevertheless, it's only today that we're getting the full picture of ARM's "clean sheet" v8 architecture, and you know what? It's pretty astounding. Top billing goes to the Cortex-A57, which is said to deliver "three times the performance of today's top smartphones" without guzzling any additional power. Alternatively, the chip could be designed to deliver the same performance as a current smartphone or tablet but make the battery last five times as long -- which would make that Surface RT just about five times nicer than it is already. How's all this possible? Read on for more.
ARM and TSMC team up on 64-bit chips and FinFET transistors
ARM and TSMC are renewing their vows and plan to continue collaborating well into the future, as they work to optimize the 64-bit v8 architecture for the Taiwanese company's FinFET transistor tech. The two will push next-gen ARM chips to 20nm and beyond, and hopefully shorten the time to market for new designs. The FinFET process should also help boost frequencies, while keeping power consumption low -- a key to the continued success of the RISC architecture. The FinFET architecture is similar to Intel's own tri-gate transistor technology that was instrumental to nudging the Core architecture forward with Ivy Bridge. After those 64-bit ARM chips are up and running at 20nm and powering your next-gen smartphone, TSMC will begin to look at even smaller processes, with an eye on 15nm next. You'll find the entire joint profession of their love for one another after the break.
Acer turns down non-tablet ARM devices, player hates the smartbook game
Acer may be going on a full touchscreen blitz at Computex, but one thing it's not doing is chasing others down the smartbook path. Talking with journos as Taipei's big gala got underway, company chairman JT Wang said that ARM was too fresh-faced to be used in anything besides a tablet, at least until 64-bit ARM architecture speeds things up in earnest. Wang wasn't too worried, though: Intel and Microsoft were recovering their "relationship" now that Windows 8 was providing a spark to reignite the love affair. That will leave Acer taking a decidedly different route than its Taiwan sibling ASUS, whose Tablet 600 carries more than a slight smartbook vibe. With ARM-based Windows 8 PCs not poised to arrive in force until early 2013, though, it will take some time before we know which course is wisest.
Dell wants in on ARM server field, says software still has some maturing to do
While the company wouldn't reveal specific plans, Dell did say it's interested in entering the server arena with an ARM-based product. Earlier this year HP debuted its first ARMv8-powered server, but Dell seems to think the launch was a tad rushed. As it said during the Q&A session of its earnings call today, CEO Michael Dell said the company had "been experimenting with making an ARM server for over a year ... but the software stack just isn't mature enough yet." It is, however, intrigued and sees "some interesting opportunities emerging."
ARMv8 detailed: 64-bit architecture, AppliedMicro first in line
Thought Windows on ARM was snazzy? Have a gander at this. The outfit's forthcoming ARMv8 architecture, the first ARM architecture to include a 64-bit instruction set, has just been detailed, with a goal to expand the reach of ARM processor-based solutions "into consumer and enterprise applications where extended virtual addressing and 64-bit data processing are required." The ARMv8 architecture consists of two main execution states -- AArch64 and AArch32 -- and we're apt to see the real benefits hit high-end servers first. The ARMv8 architecture specifications are available now to partners under license, with the company planning to disclose processors based on ARMv8 during 2012, with consumer and enterprise prototype systems expected in 2014. Head on past the break for ARM's take, or meander to the source links for AppliedMicro's gloating.
