Front view of Intel Xeon X5450

Reasons to consider the
Intel Xeon X5450

Report a correction
Much more l2 cache 12 MB vs 1 MB 12x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Much more l2 cache per core 3 MB/core vs 1 MB/core 3x more l2 cache per core
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
More cores 4 vs 1 3 more cores; run more applications at once
Newer Nov, 2007 vs Nov, 2004 Release date over 3 years later
More threads 4 vs 2 Twice as many threads
