Accuracy is generally an important consideration in computer chips, but a team of researchers led by Rice University are touting a new “inexact” chip (dubbed PCMOS) that they say could lead to as much as a fifteen-fold increase in efficiency. Their latest work, which won a best paper award at a recent ACM conference, builds on years of research in the field from the university, and is already moving far beyond the lab — some inexact hardware is being used in the “i-slate” educational tablet developed by the Rice-NTU Institute for Sustainable and Applied Infodynamics, 50,000 of which are expected to wind up in India’s Mahabubnagar school district over the next three years.

Researchers tout efficiency breakthrough with new ‘inexact’ chip
Intel had already promised that it would avoid using conflict minerals , and now it’s giving itself a more concrete timetable for that to happen. 
Ivy Bridge, Intel’s first generation of chips to use the 22nm fabrication process, is hardly out of the gate, and yet talk has already turned to the company’s next manufacturing technologies. 
While earnings calls are rarely the veritable dial-in party, sometimes they do toss up a juicy gambit or disappointing revelation. While NVIDIA was dishing out projections for Q1 2013, it pretty much quashed any hopes of seeing an in-house LTE Tegra chip in 2012. 
If you read our interview with ARM co-founder John Biggs, you know the company behind the processor in mosts smartphones had quite modest beginnings, what with an office in a barn and all. But Biggs is only part of the story, and Reghardware fleshes the rest out with a two-part series on the “unsung heroes of tech”: Sophie Wilson, Steve Furber and Herman Hauser, the team behind Acorn Computers, the British PC company that spawned ARM in the mid-80s. 
Not all iPads are made equal, even if they’re all packaged and branded identically. There’s a major new mutation within the 2nd generation tablet and it brings significantly better battery life. Specifically, the fourth and latest production model of the iPad 2 (known as iPad2,4) has not only a lower price tag ($399) but also a new 32nm processor, which is significantly smaller and more efficient than those in previous iPad 2s (which had 45nm chips and an older transistor design)
We know TSMC ‘s energy-miser 28-nanometer manufacturing process has a lot of headroom , but the company just ratcheted expectations up by a few notches. Lab workers at Taiwan’s semiconductor giant have successfully run a dual-core ARM Cortex-A9 processor at 3.1GHz under normal conditions. That’s a 55 percent higher clock speed than the 2GHz maximum that TSMC normally offers, folks, and about twice as fast as a 40nm chip under the same workload. 
We hear that pilgrims have already started flocking to the town of Ivybridge (population 12,056) in the forested depths of southwest England. Very soon though, you’ll be able to pay homage to Moore’s law without travelling further than your favorite online retailer, because the third generation of Intel Core processors has just launched and should be available to buy before the end of this month. These include eight different variants of Core i7 for desktops and notebooks (including Ultrabooks of course), plus five types of Core i5 destined for desktops only. 
So, there’s still a little while to go before Intel gives Ivy Bridge a full unveiling, with official benchmarks, pricing and all those trimmings. But in the meantime, the BBC has detailed just how different this new architecture is compared to 32nm chips like Sandy Bridge and also AMD’s coming Trinity processors. Most of this stuff we already knew — like the fact that Intel has switched to a 3D or ‘ tri-gate ‘ transistor design — but what’s new is a direct and official boast about performance. 
This isn’t the easiest time to be an AMD fan. The company’s eight-core FX-8150 desktop chip was widely panned on the review circuit, and then NVIDIA’s GTX 680 graphics card ran off with Radeon HD ‘s thunder
