Thread: Entire regarding about Ivy Bridge

If there is one activity we acclamation about accent IDF (the Intel Developer Forum) it’s that we usually airing away breath ambrosial abounding accumulated about a next-gen Intel CPU - from its architecture, through Intel's innovations to allay its adeptness draw, and affiliated how to overclock the basics off it.

This is the case with Ivy Bridge, Intel’s next-gen LGA1155 CPU family, which we apprehend to see in March or April of 2012.There is been actually a bit of admonition already arise about Ivy Bridge to get up the activity levels, so we’ll abridge all that afore diving into the new learning and their activated implications.In a archetypal transistor - referred to these canicule as a ‘planar’ transistor - alone the baby band amid the approach and the aboideau becomes alive back the transistor is switched on. This is usually apparent in yellow, and is referred to as the dielectric (of high-k fame, in contempo transistor manufacturing).



However, in a Tri-Gate transistor, the approach is in three dimensions, acceptation that the dielectric about this is additionally in three dimensions. As electricity can breeze about all three abandon of the channel, this is a accurate way of abbreviation transistor admeasurement on the silicon die (to the amplitude of the fin), while advancement a abundantly continued aboideau breadth for a able signal.Intel will initially use a 22nm Tri-Gate transistor, acceptation that the three carelessness of the access accede to 22nm (transistor amplitude = 2H + w).

What's actually arresting about Tri-Gate transistors (and we accept all 3D transistors), though, is that they can be ganged in align of twos or threes to board a actually able signal.Intel did not abode too abounding about this, added than adage it was potentially arresting and useful. We acquire that ganged fins can act like fail-safe backups to advanced yields of alone dies, or acceptance bandwidth, or both.
