Intel Xeon X5647 processor 2.93 GHz 12 MB Smart Cache
- Intel® Xeon® 5000 Sequence X5647 2.93 GHz
- 12 MB Smart Cache LGA 1366 (Socket B)
- Processor cores: 4 32 nm 64-bit 130 W
- Maximum internal memory supported by processor: 288 GB DDR3-SDRAM
Intel® Turbo Boost Technology
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® 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.
Enhanced Intel SpeedStep® Technology
Enhanced Intel SpeedStep® Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep® Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep® Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.
