hunter315 :
Haswell was the Tick, Broadwell will be the Tock
You have that backwards.
Haswell is the Tock
Broadwell is the Tick (14nm)
Skylake is the next Tock
Cannonlake is the next Tick (10nm)
I always remember it like this:
A t O ck is an Overhaul. This means new Architecture and usually a new socket.
A t I ck is an Incremental upgrade. This means Die Shrink but usually Same socket as prior gen
Oh and to the OP Arty, The Desktop and sometimes Laptop processors from Intel (lately anyway) lead the pack.
So you will see average (<$1000) desktops and most laptops get whatever the new processor is first.
Then some time after that, could be months or sometimes an entire year, the server and "Workstation" market get the same new core. These processors are often $500 to $3000 a piece so Intel is basically using the normal desktop version to flush out any bugs before they put this new design into a server.
Family names behind the scenes.
XXX-DT is usually the Desktop version.
XXX-E is the Workstation version and is usually half of a ...
XXX-EP is the 2 Socket (Dual Processor) Server and High end Workstation processor. These processors run like 85% of servers in the Enterprise (big companies). AKA E5-2600
XXX-EP4S is a newish 4 Socket design based on the 2 Socket proc. AKA E5-4600. I call it the poor man's 4S because its not the ....
XXX-EX is the 2/4/8+ Socket "Big Iron" type server. AKA E7-xxxx. These are designed with more High Availability features and while they usually have slower cores, they have more of them than the EP line and the system is designed to take hits like a failing DIMM and keep right on going without crashing the OS.
Oh and Devil's Canyon was just a "Haswell Refresh".
New design of the existing core on the existing die size.
They did this because Broadwell is late due to yield issues (manufacturing producing too many bad processors in a given batch)
