Samsung 8-core big.LITTLE chip due 2013 (but don’t expect it in the GS4)

Samsung is readying an 8-core processor using ARM's big.LITTLE architecture for a reveal on February 19, it's confirmed, pairing half powerful and half frugal cores for capable and long-lasting phones and tablets. The unnamed chip will be shown off at the International Solid State Circuits conference [pdf link] next year, a 28nm SoC which combines a pair of quadcore clusters: the first, for power, running at 1.8GHz with Cortex A15 cores, and the second, for efficiency, running at 1.2GHz with Cortex A7 cores.

Intel CEO Paul Otellini retires in May 2013

Intel's CEO Paul Otellini will retire in May, the chip company has confirmed, though no replacement has yet been found. Otellini - who joined Intel nearly forty years ago, and has been its CEO for the past eight years - will transition out of his role over a six month period, having been the primary motivator behind Intel's strategy in ultrabooks, though has also seen the company struggle to compete in mobile processors.

If Apple can ditch Intel, it will

If Apple can ditch Intel, it will

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.

AMD Opteron 6300 Series slots a 16-core Piledriver in your server rack

AMD Opteron 6300 Series slots a 16-core Piledriver in your server rack

AMD has launched its latest next-gen Opteron 6300 Series processors, aiming to power the server you buy tomorrow, and the more mainstream branch of its twin enterprise chip strategy. The new chips - which promise up to 24-percent higher performance versus the Opteron 6200 processors the new range replaces - use AMD's Piledriver core technology for reduced power consumption: that means cooler, faster servers that are cheaper to run.

Titan supercomputer goes live with potent CPU/GPU tag team

Titan supercomputer goes live with potent CPU/GPU tag team

The Titan supercomputer at the Oak Ridge National Laboratory has been upgraded, tackling complex climate change calculations with 20 petaflops worth of new processors. Under the (considerable) hood its NVIDIA's "Kepler" GPUs and AMD Opetron 6274 processors doing the heavy lifting, though NVIDIA can't resist pointing out that its graphics chips are in fact carrying 90-percent of the overall load. The GPUs, more commonly found powering gaming rigs, help make Titan "the world's fastest supercomputer for open scientific research."

Apple A6X revealed: New flagship chip

Apple A6X revealed: New flagship chip

Apple has unveiled its latest mobile chipset, the Apple A6X, replacing the already-capable A6 in the third-gen iPad, and doubling performance compared to the A5X along the way. The new chipset, a custom SoC using ARM cores, delivers not only that 2x CPU grunt but doubled graphics performance too. It's the new chipset at the heart of the 4th-generation iPad.
