Report a correction
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More l3 cache 12 MB vs 8 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
Better geekbench (32-bit) score 13,247 vs 8,859 Around 50% better geekbench (32-bit) score
Higher Maximum Operating Temperature 81.3 °C vs 75 °C Around 10% higher Maximum Operating Temperature
More cores 6 vs 4 2 more cores; run more applications at once
Better PassMark score 7,606 vs 5,519 Around 40% better PassMark score
Better performance per watt 12.05 pt/W vs 8.75 pt/W Around 40% better performance per watt
Newer Mar, 2010 vs Mar, 2009 Release date 11 months later
Supports more RAM 294,912 MB vs 147,456 MB Supports 2x more RAM
Slightly more l2 cache per core 0.33 MB/core vs 0.25 MB/core Around 35% more l2 cache per core
Better overclocked clock speed (Water) 4.39 GHz vs 4.2 GHz Around 5% better overclocked clock speed (Water)
