Report a correction
Much more l3 cache 30 MB vs 20 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
Significantly higher turbo clock speed 3.3 GHz vs 2.8 GHz Around 20% higher turbo clock speed
Much better performance per watt 12.03 pt/W vs 1.83 pt/W More than 6.5x better performance per watt
More threads 24 vs 16 8 more threads
Supports more RAM 786,432 MB vs 393,216 MB Supports 2x more RAM
Higher clock speed 2.5 GHz vs 2.4 GHz Around 5% higher clock speed
Newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Newer Jul, 2014 vs May, 2012 Release date over 2 years later
Better overclocked clock speed (Water) 2.5 GHz vs 2.4 GHz Around 5% better overclocked clock speed (Water)
