difference between sandy bridge and ivy bridge

Starting up a new PC up always gave you that hair blowback experience where you say 'wow, that sucker is fast.' That didn't happen. I mean, usually you see some kind of change.

When all was said and done, I noticed something: the computer was no different than before. A reinstall consumed a day of my time as one thing after another came up (I need Photoshop, where's the CD? Oh yeah, in a storage unit 12 miles away). I had hoped that I could get away with using my existing OS install, but no dice. The memory (16GB, 1600Mhz DDR3), storage and GPU (Nvidia GTX670) would all be transferred over. I needed a new motherboard (obviously), case, and power supply. My existing case would house the current PC, a Sandy Bridge chip with the model number Core i7-2600k, a 3.4Ghz quad-core processor. So, thanks to a courtesy chip from Intel (a Core i7-4770K, a 3.8Ghz quad-core processor), I went shopping. This summer came 'Haswell,' the tock that featured a new architecture.

There is no performance gain to be had on a 'tick' because it's just a drop in the size of the transistors they use, such as from 45nm to 32nm. It's been my personal policy to upgrade my computer on Intel's 'tocks' - when it comes out with a whole new architecture. Trying to do a new architecture and manufacturing process shrink was too much risk to be done in one fell swoop. Several years ago, Intel introduced the tick/tock model, where the 'tick' would be a shrink of the existing architecture and 'tock' would be a whole new architecture using the manufacturing process from 'tick.' This was done to spread out the risk.
