Intel's Eight-Core, Heavily-Updated Poulson Itanium Processor Unveiled

MojoKid (1002251) writes "Intel's Itanium 9500 family, codenamed Poulson, was announced today and it's the most significant refresh Intel has ever done on the Itanium family. Just moving from 65nm to 32nm technology would've substantially reduced power consumption and increased clock speeds, but Santa Clara has overhauled virtually every aspect of the CPU. Poulson can issue 11 instructions per cycle compared to Tukwila's six. It adds execution units and rebalances those units to favor server workloads over HPC and workstation capabilities. Its multi-threading capabilities have been overhauled and it uses faster QPI links between the CPUs. The L3 cache design has also changed. Previous Itanium 9300 processors had a dedicated L3 cache for each core. Poulson, in contrast, has a unified L3 that's attached to all its cores by a common ring bus."
