IBM 43W5988-RFB Intel Xeon Processor E5520 43W5988-RFB

Intel� Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it, and increased energy efficiency when you don�t.Intel� Turbo Boost Technology dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom to give you a burst of speed when you need it, and increased energy efficiency when you don�t.

Intel� Hyper-Threading Technology (Intel� HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner.

Intel� VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory intensive virtualized applications. Extended Page Tables in Intel� Virtualization Technology platforms reduces the memory and power overhead costs and increases battery life through hardware optimization of page table management.
