Next-Gen Itanium: 32nm, 8-core Poulson

Next-Gen Itanium: 32nm, 8-core Poulson

The Itanium CPU is mostly used for the ultra high end and enterprise computing needs and it uses Intel's VLIW IA-64 architecture. Code named Poulson, Intel has literally up the ante by moving to 32nm process, adding up to four more cores, and tacking on more than one billion additional transistors.


Comparison of Itanium CPUs
  Poulson Tukwila
Core/Thread Count Up to 8/16 Up to 4/8
Frequency *TBA Up to 1.73GHz
L3 Cache Up to 32MB (*TBC) Up to 24MB
Manufacturing Process 32nm 65nm
Transistor Count 3.1 billion 2.046 billion
Die Size 544mm^2 (*TBC) 699mm^2

*TBC = to be confirmed, *TBA= to be announced

The CPU also has a new feature called Intel Instruction Replay Technology, which adds a buffer for more quickly recovering from errors, allowing the chip to pick up from the last known good instruction instead of having to completely flush the pipeline. Those looking to upgrade will also be happy to hear that the upcoming IA-64 CPU is pin compatible with Tukwila.
