AMD plays both sides of the CPU wars with chips that use the same socket
Typically, you can't reuse many parts when you switch processor technologies; if you change chips, you change the entire motherboard at the same time. That won't be true for AMD in the future, though. It's working on a common chip framework, Project Skybridge, that will let 2015-era ARM and x86 system-on-chip processors share the same pin layout. In other words, a basic motherboard design could handle both CPU types.
AMD's 2014 embedded roadmap includes dedicated graphics, gaming-friendly CPU
AMD has long signaled that embedded chips will play a major role in its future, and it's backing up that claim by providing a glance at its 2014 roadmap. The highlight is Bald Eagle, a 35-watt x86 processor designed for demanding tasks like gaming; it should include up to four Steamroller cores, and it will optionally sport on-chip Graphics Core Next video. Devices that need even more visual power will use Adelaar, a dedicated graphics chipset that includes both GCN and 2GB of built-in memory. It's reportedly fast enough to be useful for PC video cards, not just the usual set-top boxes and smart TVs. Two system-on-chip designs are also joining AMD's lineup. Hierofalcon is built with data centers in mind, and carries up to eight ARM Cortex-A57 cores; Steppe Eagle, meanwhile, is a combination of upgraded Jaguar x86 cores and GCN that should speed up AMD's low-power G-series processors. With the exception of Hierofalcon, all of the new embedded chips should be available in the first half of next year. AMD hasn't named any early customers, but its embedded silicon tends to reach products that you'd recognize. Check out the roadmap after the break.
AMD details first ARM-based server chip: up to 16 helpings of Cortex-A57 clocked at 2GHz
It's hardly a secret that AMD has stepped out of its x86 comfort zone to develop an ARM-based server chip, but now we know a little more about it. Going by the name of "Seattle" and scheduled for launch in the second half of next year, it'll be built around ARM's 64-bit Cortex-A57 in either 8- or 16-core configurations, which will likely be clocked at a minimum of 2GHz. In an apparent acknowledgement of ARM's superiority at low wattages, we're told that this design has the potential to deliver 4x the performance of AMD's current Opteron X processors, with improved compute-per-watt. There's a clear limit to AMD's reliance on ARM, however, as it'll use Seattle to up against Intel's little Atoms, but will continue to sell its own x86 designs for higher-power applications. Meanwhile, we're still waiting on something more interesting from this union, which might be an ARM CPU paired with a Radeon HD graphics processor in some sort of mobile-class SoC. Guess we'll just have to be patient.
First ARM Cortex-A57 processor taped out by TSMC, ready for fab
Your current smartphone just took another spin backwards on the obsolescence cycle thanks to a new landmark from ARM and TSMC: the first Cortex-A57 has reached the "tape out" stage, meaning it's ready for mass production. The new chip will use TSMC's 16nm FinFET technology (though the transistors will be 20nm for the A57) and will bring up to three times the CPU power of current chips for the same battery life -- or a maximum of five times the battery life at the same speed. The companies said they ramped the chip from design to tape out in a mere six months, though there's no timetable for its arrival in specific devices. When it does start hitting next gen phones and slates though, expect the performance charts to get singed.
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.
