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 l3 cache 20 MB vs 0 MB Compared to all cpus, 20 MB l3 cache is just OK
Significantly 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
Much better PassMark score 19,521 vs 561 More than 34.8x better PassMark score
Higher clock speed 2.6 GHz vs 2.2 GHz Around 20% higher clock speed
Much more l3 cache per core 2.5 MB/core vs 0 MB/core Compared to all cpus, 2.5 MB/core l3 cache per core is just OK
More cores 8 vs 1 7 more cores; run more applications at once
Much better PassMark (Single core) score 2,091 vs 635 More than 3.2x better PassMark (Single core) score
More threads 16 vs 1 15 more threads
Much better performance per watt 10.97 pt/W vs 1.05 pt/W Around 10.5x better performance per watt
Supports more CPUs in SMP configuration 2 vs 1 Twice as many CPUs in SMP configuration
