Front view of AMD Opteron 6208

Reasons to consider the
AMD Opteron 6208

Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 4 MB vs 2 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much higher clock speed 3.5 GHz vs 2.2 GHz Around 60% higher clock speed
Much more l3 cache 16 MB vs 0 MB Compared to all cpus, 16 MB l3 cache is just OK
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
Much more l3 cache per core 4 MB/core vs 0 MB/core Compared to all cpus, 4 MB/core l3 cache per core is just OK
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 4 vs 2 Twice as many threads
