The IBM 43X5256 Intel Xeon X5560 Processor is a reliable solution that manages and processes data. This processor has 4 cores and 8 threads. It can handle many tasks and applications at the same time with Hyper-Threading technology. It has a base clock speed of 2.80 GHz, providing strong performance for general server workloads.
It also has 8 MB of L3 cache. This cache speeds up data access by keeping often-used information near the processor.
The X5560 supports Intel Turbo Boost Technology, which increases the processor speed and improves performance during high workloads. Moreover, it uses the LGA 1366 socket, making it compatible with servers and motherboards.
This processor also provides 6.4 GT/s QPI (QuickPath Interconnect). This allows quick communication between the CPU and other parts, like memory and the chipset.
