Intel Xeon E5-4617

Report a correction
Much higher turbo clock speed 3.4 GHz vs None Compared to all cpus, 3.4 GHz turbo clock speed is just OK
Much better geekbench 3 Multi-Core score 35,383 vs 1,127 Around 31.5x better geekbench 3 Multi-Core score
Much higher clock speed 2.9 GHz vs 1.65 GHz More than 75% higher clock speed
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 more l3 cache 15 MB vs 0.5 MB 30x more l3 cache; more data can be stored in the l3 cache for quick access later
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
Much better geekbench 3 single core score 2,644 vs 642 More than 4x better geekbench 3 single core score
Significantly newer manufacturing process 32 nm vs 40 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l3 cache per core 2.5 MB/core vs 0.25 MB/core 10x more l3 cache per core
More cores 6 vs 2 Three times as many cores; run more applications at once
More threads 6 vs 2 Three times as many threads
Newer May, 2012 vs Aug, 2011 Release date 8 months later
