Intel Xeon L5520 vs X5450
Comparing Xeon L5520 and Xeon X5450 processor market type (desktop or notebook), architecture, sales start time and price.
Xeon L5520 and Xeon X5450 basic parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state. These parameters indirectly say of CPU speed, though for more precise assessment you have to consider their test results.
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
