Compatibility

Information on Xeon L5520 and Xeon X5450 compatibility with other computer components: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.

Advantages of Intel Xeon L5520

Cheaper ($59 vs $109)

Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)

HyperThreading (allows one physical CPU function as two logical ones. It increases performance, since while one logical CPU is waiting for data, the second may still do useful work)

TXT (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)

Advantages of Intel Xeon X5450

2.7% higher performance in benchmarks

So, which one is the better CPU?
