AMD Six-Core Opteron 8419 EE

Report a correction
Supports more CPUs in SMP configuration 8 vs 1 7 supports more CPUs in SMP configuration
Significantly more l2 cache 3 MB vs 2 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
More l3 cache 6 MB vs 0 MB Compared to all cpus, 6 MB l3 cache is just OK
More cores 6 vs 2 Three times as many cores; run more applications at once
Significantly more l3 cache per core 1 MB/core vs 0 MB/core Compared to all cpus, 1 MB/core l3 cache per core is just OK
More threads 6 vs 2 Three times as many threads
Slightly lower typical power consumption 48.75W vs 52.81W Around 10% lower typical power consumption
Slightly lower annual home energy cost 14.45 $/year vs 15.66 $/year Around 10% lower annual home energy cost
Slightly lower annual commercial energy cost 52.56 $/year vs 56.94 $/year Around 10% lower annual commercial energy cost
