Intel has launched its much-anticipated Ivy
Bridge processors. The arrival of the new chips is of particular interest to
Mac users because they’re expected to be used in the next versions of the
MacBook Pro, iMac and Mac mini. The initial crop of Ivy Bridge processors
comprises quad-core i5 and i7 chipsets aimed at desktops and standard laptops.
A further release, with dual-core processors for ultra-slim laptops like the
MacBook Air, will be launched ‘later this spring’, according to Intel.
a revamped MacBook Pro be the first Apple machine to incorporate Intel’s latest
Ivy Bridge features what Intel calls 3D TriGate
technology. This allows transistors to be stacked on top of each other, rather
than laid out side by side. This is the world’s first 22 nanometre product and
we’ll be delivering about 20% more processor performance using 20% less
average power,’ Kirk Skaugen, Intel’s PC business chief told the BBC, referring
to the semiconductor manufacturing process used to build the chips.
Ivy Bridge’s integrated graphics, likely to
be used in the Mac mini, have also had a boost. The GPU can process 4K
resolution video from the latest pro video cameras and can handle real-time I
MacUser’s sister magazine PC Pro tested the
desktop Ivy Bridge chips and found they oiTered modest performance improvements
over their predecessors. However, noted reviewer David Bayon, ‘it isn’t hard to
see that the triple whammy of greater speed, improved graphics and lower power
consumption plays perfectly to the needs of [MacBook Air-style] ultrabooks,
and that’s where Intel hopes it will make an impact.’
Ivy Bridge also has built-in support for
USB 3, which makes it easier for systems manufacturers to include USB 3 buses
and ports. Apple has yet to adopt USB 3, however, and it’s not thought it will
make use of this feature. There’s also support for Apple’s current preferred
I/O technology, Thunderbolt.
Skaugen said Intel would produce around 50%
more Ivy Bridge chips than it did last year’s Sandy Bridge, but high demand
meant supply would still be constrained.
Google Drive vies for the post-iDisk
As we predicted last issue, Google has
launched a general purpose cloud storage service, Google Drive. It provides
5GB of free storage to Google account holders, and offers several features that
integrate with those of Google’s existing services that Larry Page has yet to
Unlike Apple’s iCloud, which only stores
preset types of media and is accessed from within apps or the browser, Google
Drive can be used as a virtual folder on your Mac or PC desktop, like Dropbox,
or accessed from within a Google account.
In a blog post, Sundar Pichai, Google’s
senior vice president of Chrome and apps, explained: ‘Google Docs is built
right into Google Drive, so you can work with others in real time on documents,
spreadsheets and presentations.’ Google Docs users can currently collaborate on
documents by electing to share them with other users. It’s not clear yet how
the ‘real time’ element of Docs in Google Drive will work.
Google+ users will be able to share photos
they’ve stored on Google Drive by sending the URL of the image, and soon Google
Mail users will be able to add Google Drive files as attachments to emails.
Scanned documents uploaded to Google Drive
will be converted to text via OCR, and will be searchable. Google says it will
also use image recognition technology to identify pictures, which might raise a
Google Drive is now available for the Mac,
with an iOS version due to launch soon. See www.drive.google.com for details.

users, whose iDisk storage will be terminated at the end of June, in MacUser,
