Differences What are the advantages of each

Front view of Intel Xeon E3-1260L

Reasons to consider the
Intel Xeon E3-1260L

Report a correction
Much higher clock speed 2.4 GHz vs 2.1 GHz Around 15% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
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 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More l3 cache per core 2 MB/core vs 1.5 MB/core Around 35% more l3 cache per core
Newer Apr, 2011 vs Apr, 2009 Release date over 1 years later
