Titan steals No. 1 spot on Top500 supercomputer list

Predictions that Oak Ridge National Laboratory's Titan supercomputer had become the most powerful machine in the world have turned out to be right.

The machine, powered by Nvidia graphics processors and Advanced Micro Devices computer chips, stole the No. 1 spot on the Top500's list from another U.S. machine, Lawrence Livermore National Laboratory's Sequoia.

Sequoia, which uses processors from IBM, became the top computer in June with a performance of 16.32 petaflops a second. Titan beat that showing, sending Sequoia to second place on the list, with a result of 17.59 petaflops per second. … Read more

Samsung to Apple: Our chips will cost you more

Samsung has hiked the price of its mobile processors by 20 percent, but to only one of the Korean technology giant's customers: Apple.

The report comes from The Wall Street Journal's MarketWatch, citing a person familiar with the negotiations between the two smartphone and tablet makers.

According to the report, Samsung requested an increase in the price of the mobile "application" processor supplied to Apple, which the Cupertino, Calif.-based technology giant was forced to swallow as only Samsung provides the specific hardware required to make the shiny rectangles of various sizes work properly. … Read more

Apple aims to dodge 'Intel tax' (Q&A)

Apple has become a formidable chip designer with its A series chips. And that's probably not good news for Intel, says a chip expert.

I asked Nathan Brookwood, principal analyst an Insight 64, about the shifting dynamics of the relationship that began in 2006, when Apple dropped the PowerPC for its Mac line.

Brookwood said, in effect, that if you reduce the relationship to the fact that Apple must continue to pay an "Intel tax" for chip designs it doesn't control, the future is not very cheery.

Q: What is the significance of Apple's A6 … Read more

Intel's tiny desktop PC for DIYers coming this month

Online retailers will begin selling a 4.5-inch-wide Intel-branded desktop PC for do-it-yourselfers later this month.

The product name is a mouthful -- the "Next Unit of Computing," or NUC for short.

"It's geared more to home theater/home media center," said Intel spokesperson Dan Snyder. One usage scenario he suggested: slap it on the back of a wide-screen display (see photo below).

But note: as Anandtech points out, it is truly a bare-bones system aimed at DIYers. … Read more

Nvidia still has a lot to prove in the mobile market

Nvidia may be flying high on its tablet wins, but it still has a long way to go before it can call itself a real mobile player.

The Santa Clara, Calif., company, traditionally known for making graphics processing units found in computers and game consoles, has been counting on its Tegra mobile chip to help offset weakness in its core PC market. So far, it hasn't been enough. Nvidia is showing up in many tablets, but its presence in smartphones is minimal. In addition, the bulk of Tegra sales are for a couple of tablets, the Google Nexus 7 … Read more

Nvidia CEO: People buying tablets instead of cheap PCs

Tablets really are replacing PCs now that the latest version of Windows has launched, graphics- and mobile-chip maker Nvidia said.

But at least right now, Nvidia's mobile business isn't big enough to offset the less-than-merry computer market this holiday season.

It's not exactly shocking that tablets have been eating into sales of PCs. Computer makers have noted the trend, and so have Nvidia chip rivals Intel and Advanced Micro Devices.

But what's interesting is that Nvidia says consumers now realize that a "great tablet is better than a cheap PC." That could signal a … Read more

Qualcomm's Q4 shows gap between mobile, PC chipmakers

In case the market needs more evidence of the strength of mobile versus PCs, all it has to do is look at Qualcomm.

The wireless-chip maker, which helped popularize the CDMA technology used in cell phones, today reported quarterly financial results that were better than it had anticipated, and it provided bullish projections for the current period and year.

Its strong results -- which sent shares up about 8 percent in after-hours trading -- contrast pretty sharply with the dismal forecasts from many other semiconductor companies, most notably PC chip giant Intel. Intel last month gave a fairly grim outlook … Read more

Will Apple's silicon be good enough for a Mac?

Apple is starting to release some scary-good silicon. But can it muscle out Intel?

Last decade, the question was, will Apple go Intel? After years of speculation, that finally happened in 2006, when Apple dropped the PowerPC for its Mac line.

So are we now on a similar trajectory, as a Bloomberg story speculates, with Apple eventually evicting Intel from its Macs and using its own internally developed processors?

A quick look at the latest Apple silicon shows the company is on the right track. The A6X is a serious piece of silicon that makes the newest gen 4 iPad … Read more

iPad Mini vs. iPad 4: A glance at raw benchmarks

So how much faster is the fourth-generation iPad than the iPad Mini? Raw benchmarks show a yawning gap between Apple's newest tablets.

Though benchmarks are typically more theoretical than real-world (that is, you won't necessarily feel a big speed boost using everyday apps), they're instructive because they show the potential of the underlying silicon.

And that potential can become very real when specific applications, such as games, are optimized to tap into the redesigned circuits of a new chip -- in this case, Apple's new A6X, a faster version of the A6 in the iPhone 5. … Read more
