ARM's Mali-T604 makes official debut, we get a first look at the next-gen GPU (hands-on video) (update: it's the Exynos 5)
Think those are some pretty slick graphics in your Galaxy S III? Samsung's latest smartphone packs some mighty graphics prowess of its own, thanks to the Mali-400 MP GPU, but once you spend a few minutes with the Mali-T604, the company's next-generation chipset, the improvements become quite clear. After seeing the Mali-T604 in action, as we did at SIGGRAPH today, the capabilities leave us hopeful for the future, and perhaps feeling a bit self-conscious about the silicon currently in our pockets. The reference device on hand was operating in sync with a variety of unnamed hardware, protected from view in a relatively large sealed box. We weren't able to squeeze many details out of ARM reps, who remained mum about the demo components, including clock speed, manufacturer and even fabrication size. What we do know is that we were looking at a quad-core Mali-T604 and dual-core ARM Cortex-A15 processor, with a fabrication size in the range of "28 to 40 nanometers" (confirming the exact size would reveal the manufacturer). Clock speed is also TBD, and the early silicon on demo at the show wasn't operating anywhere close to its top end. In order to experience the T604, we took a look at three demos, including Timbuktu 2, which demonstrates elements like self shadowing and depth of field with OpenGL ES 3.0, Hauntheim, which gives us an early look at physics simulation and HDR lighting with OpenCL, and Enlighten, which rendered silky smooth real-time illumination. You can see all of the demos in action after the break, and you can expect T604-equipped devices to make their debut beginning later this year -- ARM says its working with eight manufacturers to get the licensed tech to market as early as Q3. Update: ARM has just confirmed to us that this reference device is running off an Exynos 5 Dual chip (up to 1.7GHz), which means the following video is also a heads-up on what Sammy has in store for us in its forthcoming devices.%Gallery-161934%
ARM announces new quad-core Cortex-A15 Hard Macro variant
It's pretty much a year to the day that we reported the possibility of a quad-core Cortex-A15 from ARM, and look what just came across the wire! It's the Cortex-A15 Hard Macro -- the first design from ARM we're aware of that packs four A15 cores. The Hard Macro edition is of particular interest as it aims to help manufacturers bring products to market more quickly and at a lower cost. The chip variant runs at 2GHz, with performance of over 20,000 DMIPS if you were wondering. Notably, it operates with the same power usage of the A9 hard macro, which should mean it's got good efficiency credentials, and it's the first in the family to be based on 28nm process. There's no indication where we might see this turning up, but with the firm spilling the full details at the IEEE Symposium later this week, we're sure we'll find out soon enough.
Reported Tegra 4 roadmap hints at LTE, Q1 2013 release
Time to put on our "skepticles" as we pore over some reportedly leaked Tegra 4 details. NVIDIA CEO Jen-Hsun Huang went on record saying that we could expect a new Tegra "every single year", so if anything, the fourth iteration of the series is slightly overdue. Chinese site VR-Zone, however, thinks it's got the inside skinny on how the next deployment might look. If its alleged roadmap leaks are to be believed, there will be four variants, three with a quad-core ARM Cortex A15 configuration, with clock speeds from 1.2 to 2.0GHz. What caught our eye a little more, though, was the "SP3X" flavor. Not because it favors the A9, but because it appears to bring LTE to the table right off the bat. That said, given that it's not that long since NVIDIA announced the same for Tegra 3, we can't help but wonder if something just got lost in translation.[Thanks Rizwan]
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.
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.
