We hear that pilgrims have already started flocking to the town of
Ivy bridge (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. Those watching out for cheaper dual-core i5, i3 and
Pentium-branded options will have to wait a little longer, because
today's launch is all about the high-end. And just how high is 'high'?
Judging from the gossip we've heard, and from benchmarks of leaked desktop and notebook chips, we're looking a significant improvement over Sandy Bridge. But if you want the first official boasts, then read on.

Ivy Bridge is a loud 'tick' in Intel's product cycle, with a much
smaller 22nm fabrication process instead of the 32nm silicon found in
Sandy Bridge (a tock) and Westmere (the previous tick, back in 2010).
Stare at your fingernail for 22 seconds and you'll see it grow by the
size of one transistor -- a world first for a mass-produced chip,
according to Intel. To pack more into the same space, the transistors
benefit from a 3D or tri-gate design, which means they're arranged over fins that protrude from the surface of the silicon base rather than just lying flat.
Having smaller, lumpier transistors doesn't necessarily translate into
radically different performance, and indeed Intel is making quite modest
claims in that department: e.g., up to eight percent improvement in the
Core i7-3820QM compared to the i7-2860QM running the SYSmark benchmark,
or up to 22 percent improvement when running a multi-threaded
application like Cinebench. On the other hand, shrinking the silicon
does make
it more energy efficient, which bodes well for the battery life of
Ultrabooks and Macbooks everywhere, and it also frees up space for Intel
to pack more technology on each chip.

The main beneficiary of that extra room is the integrated graphics. In
those chips which have superior HD 4000 hardware, the GPU component will
now occupy around a third of the chip's 160mm2 die size. Sandy Bridge's
HD 3000 graphics were pretty good for many tasks, and could readily
handle a bit of Medieval 2, but they weren't up to modern 3D gaming and
they were outclassed by the Radeon HD visuals on AMD's Fusion chips.
Intel claims the fattened-up HD 4000 will deliver a minimum 50 percent
improvement in 3D performance and will play 100 percent of recent games
out of the box -- though it didn't specify frame rates or graphical
settings, so we're not exactly sure how to interpret that. Chips with HD
2500 graphics should be 10 to 20 percent superior to HD 2000, and all
the new chips will support DX11, OpenCL v1.1 (which allows use of the
GPU and the CPU for compute tasks) and OpenGL 3.1. That said, Intel was
keen not to overplay gaming prowess in our briefing, acknowledging that
"the majority of high-end gamers will still use discrete graphics."

If you're more into multimedia than gaming as such, then there are
couple of nuggets here for you too: Quick Sync accelerated video
encoding will get a 50 to 80 percent bump, while support has also been
added for Handbrake, the open source video transcoder.
Once you
get past the main CPU and GPU improvements, you're down to a long
shopping list of much smaller upgrades such as onboard USB 3.0 support,
PCIe 3.0, triple display support and improved overclocking, the
usefulness of which will depend on your habits. Check out the Intel
slide below for more detail.
That's it! And the best thing is that Intel is giving you all of this
stuff while asking nothing in return, except at least $174 for a Core i5
desktop chip and at least $278 for a desktop i7. We're missing complete
pricing for the mobile chips, but the top-end notebook i7 processors
will start at $378 (for the i7-3720QM) and rise to $1096 for the maximum
spec i7-3920XM. If you're getting a desktop chip for your own build,
you'll probably want to budget for a new Series 7 motherboard
to go with it, although very recent Series 6 boards should also be able
to host an Ivy Bridge chip if they have the right firmware -- the
socket is still LGA 1155.
