The Ivy Bridge Preview: Core i7 3770K Tested

I still remember hearing about Intel's tick-tock cadence and not having much faith that the company could pull it off. Granted Intel hasn't given us a new chip every 12 months on the dot, but more or less there's something new every year. Every year we either get a new architecture on an established process node (tock), or a derivative architecture on a new process node (tick). The table below summarizes what we've seen since Intel adopted the strategy:

Intel's Tick-Tock Cadence
Microarchitecture	Process Node	Tick or Tock	Release Year
Conroe/Merom	65nm	Tock	2006
Penryn	45nm	Tick	2007
Nehalem	45nm	Tock	2008
Westmere	32nm	Tick	2010
Sandy Bridge	32nm	Tock	2011
Ivy Bridge	22nm	Tick	2012
Haswell	22nm	Tock	2013

Last year was a big one. Sandy Bridge brought a Conroe-like increase in performance across the board thanks to a massive re-plumbing of Intel's out-of-order execution engine and other significant changes to the microarchitecture. If you remember Conroe (the first Core 2 architecture), what followed it was a relatively mild upgrade called Penryn that gave you a little bit in the way of performance and dropped power consumption at the same time.

 

Ivy Bridge, the follow-on to Sandy Bridge should be a tick but because of significant improvements on the GPU side Intel is calling it a tick+. We managed to get our hands on an early Ivy Bridge system and ran it through some tests to determine exactly how much of an improvement is coming our way in a couple of months.
