The Intel Quad-Core 3.16 GHz processor is a 12 megabyte (MB) cache central microprocessor. Its 3.16 GHz quad-core processing is enhanced with a front-side bus (FSB) speed of 1333 MHz. The Intel Xeon X5460 has four threads and a 12 MB L2 cache. The Intel Quad-Core 3.16 GHz processor is a 64-bit CPU which contains several brand-specific features, including Intel Hyper-Threading Technology, Virtualization Technology (VT-x), and Enhanced SpeedStep Technology. It also features demand-based switching, thermal monitoring, BitLocker, and Intel VT-x with Extended Page Tables (EPT). Users concerned with compatibility should note that the Intel Xeon X5460 was launched in the fourth quarter of 2007. This central microprocessor has a bus-to-core ratio of 9.5. This means that the external (bus) clock cycles nine times for every five internal CPU clock cycles. It follows from this that the Intel X5460 handles more processing capacity than those demanded by plug-in peripherals. In other words, The Intel Quad-Core 3.16 GHz processor does not slow down as much as if the ratio was even.
