IBM squeezes 30 billion transistors into a fingernail-sized chip

Who said Moore’s Law was dead? Certainly not IBM or its chip partners Globalfoundries and Samsung. The trio has developed a transistor manufacturing process that should pave the way for 5-nanometer chips . While the team etched the chip using the same extreme ultraviolet lithography (EUV) used for the breakthrough 7nm chip , it ditched the common FinFET (fin field effect) transistor design in favor of stacks of silicon nanosheets. The switch makes it possible to fine-tune individual circuits to maximize their performance as they’re crammed into an incredibly small space. How small? At 5nm, the group says it can squeeze 30 billion transistors into a chip the size of a fingernail (see below) — not bad when the 7nm chip held 20 billion transistors a couple of years ago. IBM sees the technique helping its own cognitive computing efforts as well as the Internet of Things and other “data-intensive” tasks. However, it’s also painting a rosy picture for the future of mobile devices — it imagines phones having “two to three times” more battery life than current devices . That’s likely optimistic (phone makers tend to focus on speed over longevity), but it won’t be shocking if future hardware is both faster and wrings out a little more from every charge. Just don’t expect to see real-world examples of this for a while. We haven’t even seen devices shipping with 7nm chips (they’re not expected until 2018 at the earliest), so it could easily be a couple of years or more before 5nm arrives. Still, that 5nm is even on the roadmap is important. Chip designers won’t have to reinvent the wheel to get meaningful improvements, and you won’t have to worry about device performance growing stale for at least the next few years. Source: IBM

Verizon’s ‘LTE Advanced’ network promises 50 percent higher speed

Every wireless carrier has various tests that say its network is the best, but most still view Verizon as the best overall choice when looking for that all-important combo of speed and reliability. (That combo doesn’t come cheap , of course.) Today, the company is announcing a new focus on speed: with the rollout of “LTE Advanced, ” Verizon claims that users will see “50 percent higher peak speeds.” The new speed bump is available to users in 461 cities across the country. Of course, it’s going to take significant testing to verify the veracity of Verizon’s claims. Verizon says that LTE Advanced works by combining the multiple bandwidth channels your phone can use into what’s effectively one bigger, faster pipe to your phone. “Typical” download speed will stay around 5 to 12 Mbps, but combining two channels can net peak speeds up to 225 Mbps — that’s a lot faster than most home broadband, let alone what you’ll usually see on your smartphone. The carrier also says that it can combine three channels for speeds close to 300 Mbps. Verizon’s estimates for “typical” speeds seem low to us, but there’s no question that two- or three-channel speeds are significantly faster than what the carrier currently offers. Even if Verizon only reaches half of what it promises for peak speeds, it’s a pretty significant boost over the status quo. It’s not at all clear what circumstances will let your phone take advantage of these higher speeds, however. Verizon vaguely says that it’ll kick in “when you need it most, ” typically under conditions with “big data use.” Still, the potential for faster download speeds can’t hurt. To take advantage of LTE Advanced, you’ll need a relatively recent smartphone — Verizon says Samsung’s Galaxy S6 and S7 are compatible with the service, as well as various Moto Droids and iPhone models. There’s a link in Verizon’s press release that claims to show all LTE Advanced phones, but the bizarre selection of devices there does not cover any recent devices, so we’re assuming that’s a mistake.
