Engadget Primed: are multi-core chips worth the investment?
Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. My, how times have changed over the last eight months. At CES 2011, we ecstatically witnessed the introduction of mobile devices with dual-core CPUs and drooled over the possibilities we'd soon have at our fingertips. Now, we look down at anything that doesn't have more than one core -- regardless of its performance. Not only are these new chips quickly becoming mainstream, Moore's Law is in full effect with our handheld devices since tri-core and quad-core systems are just over the horizon. We can't even fathom what's in the pipeline for the year 2015 and beyond (we don't think we're too far away from that 3D shark seen in Back to the Future 2). Let's not get too far ahead of ourselves here, however. After all, we first need to wrap our puny human minds around the idea of what this newfound power can do, and why it's changing the entire landscape of smartphones and tablets. In this edition of Primed, we'll focus on why multicore technology makes such a difference in the way we use our handheld devices, whether we should even consider purchasing a handset with a single-core chip inside, and why one-core tech is so 2010. Check out the whole enchilada after the break.
ARM hopes to strengthen grip on mobile PCs, take 50 percent of the market by 2015
We've already heard rumors that chip designer ARM has been trying to get its wares into the Macbook Air. While we can't add anything to that particular story, we do have further evidence that ARM is going beyond smartphones and tablets in order to target bigger form factors. The company's president, Tudor Brown, has just appeared at Computex to declare that ARM wants to conquer the "mobile PC market", where the company currently only has a 10 percent share. He's aiming for 15 percent by the end of this year, and an Intel-provoking 50 percent by 2015. "Mobile PC" is a pretty ambiguous category, but we think it's safe to assume the focus is on low- and mid-power netbooks and ultraportables. Such devices could potentially run off ARM's forthcoming multi-core chips -- like perhaps the quad-core beast inside NVIDIA's mind-blowing Kal-El processor, or the more distant Cortex-A15. It's hard to imagine these tablet-centric chips ever competing with Intel's top performers, but four years is a mighty long time in this business.
Qualcomm's next-gen Snapdragon roadmap leaks, exhibits great expectations (updated)
Seems like we just can't get ARM's next-generation Cortex-A15 system-on-chip out of our minds. Having figured as a headline item in LG's ARM licensing deal this morning, it's now shown up on a leaked Qualcomm roadmap, landing itself a lynchpin role in that company's Snapdragon future. Alas, Qualcomm had been promising for the earliest of its MSM8930 / 60 and APQ8064 Snapdragons to be sampling in Q2 of this year, but this latest schedule shows them as sampling at the end of 2011 (see update). This isn't hugely surprising in light of ARM's recent forecast of Cortex-A15 devices in "late 2012," but it'll be disappointing to users keen to be exploiting quad-GPU and quad-CPU mobile rigs as soon as humanly possible. Guess that just leaves us waiting for the NGP or NVIDIA's quad-core SOC in August. Hit the source link for more on Qualcomm's plans for the near and distant future. [Thanks, Mike] Update: Qualcomm got in touch to correct the timing here. The company's 3G/LTE MSM8960 chipset remains on track to sample in this quarter, as promised in the company's latest earnings report. The other two parts were already expected to come later, so there's no delay to speak of. Just juicy specs.
LG licenses ARM Cortex-A15 and Mali-T604 graphics, starts scheming up mobile processors of its own
Some of LG's brightest attractions at the moment are the dual-core Optimus 2X and Optimus 3D smartphones and similarly equipped Optimus Pad tablet. The only problem with them? Those multicore chips are produced by NVIDIA for the 2X and Pad and Texas Instruments for the Optimus 3D, leaving LG a clear step behind its arch-nemesis Samsung who is producing its own dual-core system-on-chip. So what else could LG possibly do but buy its own ARM license -- specifically for the Cortex-A9 design that is dominating today and the Cortex-A15 with Mali-T604 graphics that promises to rule the mobile world from 2012 onwards -- and start churning out its own processors? The Korean company certainly has the budget, if not the manufacturing facilities, to produce such chips at volume, and we're all for seeing another competitor enter the ARM arena. This licensing deal also reminds us that the last fresh licensee to ARM's blueprints was Microsoft -- so we can now look forward to two industry giants bringing their technical expertise to this rapidly growing marketplace. See LG's full press release after the break.
ARM predicts dual-core Cortex-A15 devices in late 2012, quad-core variants 'later on'
Smartphones and tablets, the two hottest categories of consumer devices right now, are dominated by ARM processor designs, so when the company speaks up about its product roadmap, we're inclined to listen in close. The next generation of ARM system-on-chip has been dubbed Cortex-A15 and was expected to ship in 2013, but that's now been accelerated slightly to late 2012, which is when we're told to expect actual devices on sale with A15 silicon on board. Single- and dual-core variants will get us started, before quad-core options start filtering through in 2013. ARM promises a stunning fivefold improvement in performance over current Cortex-A9 SOCs and already has NVIDIA, Samsung, ST-Ericsson, and Texas Instruments signed up as licensees for that new hotness. So now even Samsung's "desktop-class" 2GHz dual-core chip that's slated for 2012 has a reason to look over its shoulder. Happy times!
TI announces OMAP 5: two high-performance and two low-power cores, devices next year
We're still waiting for the first OMAP 4 devices to hit the market, but TI's planning ahead -- way ahead -- with its announcement today of the OMAP 5 platform that really kicks things into high gear. The headline feature would be the inclusion of two Cortex-A15 cores, each running at up to 2GHz; Cortex-A15 is the fastest architecture ARM has announced to date, featuring performance roughly 50 percent better than Cortex-A9 at the same clock speed. What's more, there are another two Cortex-M4 processors along for the ride, ready to take over less intensive tasks at much lower power consumption to improve device responsiveness. The platform can support up to four cameras operating at the same time, offer 3D playback, recording, and 2D upsampling to 3D at 1080p resolution, and control up to 8GB of RAM. The chips start sampling to device manufacturers in the second half of this year with retail devices expected in the second half of 2012. Follow the break for the full press release.
ARM intros next-gen Mali-T604 embedded GPU, Samsung first to get it (update: video)
Promising "visually rich user experiences not previously seen in consumer electronics devices," ARM has introduced its latest embedded GPU architecture, Mali-T604, at its Technology Conference 2010 in California today. Though we're unlikely to see it in devices any time soon, the introduction means that the new design is available to ARM licensees -- and notably, the company points out that partner Samsung will be the first to get hooked up. Considering Sammy competes in the high-end embedded system-on-chip space already with its ARM-based Hummingbird line of cores, adding in the Mali-T604 is probably the next logical step for them. ARM says that it's designed "specifically" with the needs of general purpose GPU computing in mind and includes extensive support both for OpenCL and DirectX, so look for some insane number-crunching capabilities on your next-generation phone, tablet, and set-top box. Follow the break for ARM's press release. Update: We sat down with ARM's Jem Davies to get some more details about the new Mali, and discovered it's only the first of several potential next-gen GPUs to come as part of the Midgard platform -- while this particular processor is available with up to four shader cores, successors might have more. The T604 itself is no slouch, though, as it can theoretically deliver two to five times the performance of the company's existing Mali 400 GPUs core for core and clock for clock -- which themselves run circles around the PowerVR SGX 540 competition if you take ARM at its word. Davies told us that not only does the Mali-T604 do DirectX, it supports the game-friendly DirectX11 as well as the always-popular OpenGL ES 2.0, and will appear in an system-on-a-chip together with an ARM Cortex-A15 "Eagle" CPU, when both are eventually baked into silicon several years down the road. Of course, in the eyes of marketers the future is always now, so get a look at conceptual uses (hint: augmented reality) for ARM's new Mali right after the break.

ARM reveals Eagle core as Cortex-A15, capable of quad-core computing at up to 2.5GHz
Way to take the wind out of our sails, ARM -- no sooner does your dual-core Cortex-A9 finally ship, do you reveal an even more powerful smartphone, smartbook and server-slaying beast. The Cortex-A15 MPCore picks up where the A9 left off, but with reportedly five times the power of existing CPUs, raising the bar for ARM-based single- and dual-core cell phone processors up to 1.5GHz... or as high as 2.5GHz in quad-core server-friendly rigs with hardware virtualization baked in and support for well over 4GB of memory. One terabyte, actually. Like we'd heard, the ARMv7-A "Eagle" chips are destined for Texas Instruments, but ST-Ericsson and Samsung as also named as "lead licensees," so we fully expect to see some badass silicon powering a Galaxy when the 32nm and 28nm parts ship in 2013. Press release and video after the break, replete with ARM partner companies fawning over the new hotness. We can't really blame them.
