Intel will build on their series of Core i3/i5/i7-processorer. Here we have come to the fourth generation. The development is a so-called tick / tock-strategy:
Tick : A new generation of improved process technology, the latest reduced from 45nm -> 22nm
Tock : A new generation with the same process technology, but with major internal improvements in the architecture.
Thus alternating improvements in the process and in the architecture. Process improvement is about how small the electronic circuit is, and here you come down on the PCB tracks of just 22nm (it's small!).
The last two generations were codenamed Sandy Bridge, which was a "tock" and Ivy Bridge (a "tick").
The next is Haswell (a "tock").
The Haswell processors are based on the same 22nm processor architecture as in Ivy Bridge-processorne from 2012, but optimized internally with a number of improvements. The main findings are:
New instructions set AVX2 (Advanced Vector Extensions)
Twice as fast in calculations with flowing point multiply / add. Now you can run two calculations per. clock cycle. Doubled bandwidth in the L1 cache. Now 64/32 bytes read / writes per. clock cycle instead of the previous 32/16 bytes per. cycle.
Better video coding
Hardware / based codecs for SVC (scalable video codec) and MJPEG (Motion JPEG).
New Power Control Unit.
the PCU is an integrated unit in the chip that take particular care of disconnecting/ scaling down activity that is unnecessary to save power.
The new controller should provide significantly faster awakening from deep sleep. The awakening has previously taken up to about 2 seconds, which is too slow in comparison with an iPad, which almost immediately comes to life from deep sleep. Haswell will be just as quick to wake up as an iPad - and it is vital for use in tablets and the new notebooks.
