Intel Corp. said on Tuesday that it began mass production of code-named Ivy Bridge central processing units (CPUs) using 22nm process technology in the third quarter of this year. The initialization of production at 22nm node not only ensures Intel's ability to continue driving performance of computer chips upwards every year, but confirms the company's production technology leadership.

"During the third quarter, we began volume production of Ivy Bridge on our 22nm process technology. 22nm will usher-in the era of 3D transistors, which will pay dividends in power, performance and density for generations to come," said Paul Otellini, chief executive officer of Intel, during a conference call with financial analysts.


Intel's 22nm chip, presumably Ivy Bridge

According to Intel, the 22nm 3D tri-gate transistors provide up to 37% performance increase at low voltage versus Intel's 32nm planar transistors, which means that operating voltage and thus power consumption can be further reduced with present levels of performance.

Ivy Bridge will generally inherit Sandy Bridge micro-architecture and will sport a rather significant number of improvements. Firstly, it will have certain improvements that will boost its performance in general applications by around 20% compared to Core i "Sandy Bridge" chips (e.g., enhanced AVX acceleration). Secondly, the forthcoming chip will have a new graphics core with DirectX 11 and OpenCL 1.1 support, 30% higher performance compared to the predecessor as well as new video processor and display controllers. Thirdly, Ivy Bridge will feature PCI Express 3.0 x16 interconnection as well as PCIe 2.0 x4 controller. In fourth, the processor will support a number of power management innovations. The CPU is made using 22nm process technology.

Intel will release its code-named Ivy Bridge central processing units for desktops in March or April, 2012.

That die photo is definitely of the 32nm dual core Westmere die, not Ivy Bridge. Notice the cache design (definitely Nehalem/Westmere) and the lack of a large area of integrated graphics circuitry.

Not being that familiar with a side by side comparison of the 32 vs 22nm I can only say "Good Catch". Ya caught someone asleep at the switch :-)

77/95W = 0.81 so I'm guessing that's roughly 20% better "performance per watt". I don't see how 20% clock for clock performance increase is possible.

If you actually read the whole slide you'll see the 37% and 50% figures are regarding 3D Tri-Gate Transistors, not the whole CPU.

Really, that's what that means?

"it will have certain improvements that will boost its performance in general applications by around 20% compared to Core i "Sandy Bridge" chips"

37% better performance at low voltages is referring to the transistors themselves and how they operate. With the new Tri-Gate transistors, they can achieve, wait for it, 37% better performance in "switching"/"on/off" at low voltages which means they can reduce power consumption greatly while still upping performance at the transistor level. Or on the flip side, they can keep performance at a constant and realize a greater than 50% power reduction.

And to answer your question, less than 1W idle is not likely, especially with such a high performing chip, but you will see chips with a TDP of 45w. I believe they will be configurable and some mobile chips will be configurable from 35w/45w/55w depending on the platform it will be installed in and the cooling parameters.

Don't be mad Bulldozer failed to live up to expectations. Intel is doing some awesome things with the release of Ivy Bridge. Embrace it as it will keep the industry moving forward. AMD hired Papermaster to head R&D to get them back on track so Intel is forcing AMD hand, which will make AMD better. That will force Intel's hand and make Intel Better. We consumers benefit from competition, lower prices, and awesome chips.

Considering that there is no other competition out there, the processor can be even only 1% faster than the current Intel lineup, it will still be the fastest desktop processor on the Planet. Shame to you AMD!

AMD's failure to deliver a competitive processor to go up against Sandy Bridge put a knife in them. Ivy Bridge will twist the knife already inside of AMD right now for its Bulldozer failure.
