What You Should Know about the Intel Xeon E5-4650 Processor
The Intel Xeon E5-4650 processor is designed to enhance the capabilities of servers, workstations, and embedded systems. Although based on the same architecture as the standard consumer-oriented Intel processors, the E5-4650 is intended for virtual environments and enterprise-class computing, thanks to its eight cores and 20MB of L3 cache.Can you combine multiple processors together?
Yes, the Intel Xeon E5-4650 can work with four-socket platforms to scale up memory-intensive applications. That means you can combine up to four processors at once for a maximum of 32 cores and close to 1TB of DDR3 memory.Are there different versions of the Intel Xeon E5-4650?
There are two slightly different versions of the processor. The standard E5-4650 operates at a clock speed of 2.7 GHz and has a thermal design power (or the maximum amount of heat that it is designed to generate under any workload) of 130 watts. It also has slightly better turbo-boosting capabilities. A low-voltage version operates at 2.6 GHz and has a thermal design power of 115 watts. It can be identified by the name E5-4650L.What are some hardware features of the Xeon E5-4650?
The Xeon E5-4650 is equipped with the following features:
- Hyper-threading: Hyper-threading is the ability to execute multiple processes, or threads, within a single core of the CPU. This allows more work to get done in parallel.
- Virtualization: Virtualization can create multiple virtual platforms from a single hardware platform, so you can isolate your activities into completely separate partitions.
- Idle State: This technology saves power when the processor is idle.
- Enhanced SpeedStep: Depending on the amount of work, SpeedStep can dynamically change the clock speed and voltage in tandem between different levels or states. This keeps power consumption to a minimum until more power is needed.
- Turbo Boost: Turbo Boost accelerates the clock speed when there is extra thermal headroom available.
- Thermal Monitoring: A sensor is embedded on the CPU to carefully monitor the temperature and protect against potential thermal failures.
The Xeon E5-4650 protects your network against any unwanted access.
- Intel Trusted Execution: This technology verifies the authenticity of platforms on the network and allows applications to run in their own space, protected against any other software.
- Execute Disable Bit: This technology reduces exposure to harmful software that may attempt a buffer overflow attack.
- AES New Instructions: AES provides additional encryption, authentication, and random number generation.
