Front view of Intel Xeon E3-1230 v2

Reasons to consider the
Intel Xeon E3-1230 v2

Report a correction
Much higher clock speed 3.3 GHz vs 2.5 GHz More than 30% higher clock speed
Much better overclocked clock speed (Air) 3.67 GHz vs 2.5 GHz More than 45% better overclocked clock speed (Air)
More l3 cache 8 MB vs 6 MB Around 35% more l3 cache; more data can be stored in the l3 cache for quick access later
More threads 8 vs 4 Twice as many threads
Newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Water) 3.5 GHz vs 2.5 GHz More than 40% better overclocked clock speed (Water)
More l3 cache per core 2 MB/core vs 1.5 MB/core Around 35% more l3 cache per core
Newer May, 2012 vs Apr, 2009 Release date over 3 years later
