Report a correction
Much more l3 cache 20 MB vs 8 MB 2.5x more l3 cache; more data can be stored in the l3 cache for quick access later
Much more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
More cores 8 vs 4 Twice as many cores; run more applications at once
Much better performance per watt 6.61 pt/W vs 3.52 pt/W Around 90% better performance per watt
More threads 16 vs 8 Twice as many threads
Supports more RAM 393,216 MB vs 33,556.48 MB Supports around 11.8x more RAM
More l3 cache per core 2.5 MB/core vs 2 MB/core 25% more l3 cache per core
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
