Intel Pentium E5400

Report a correction
Much more l2 cache 2 MB vs 0.5 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly higher clock speed 2.7 GHz vs 2.2 GHz Around 25% higher clock speed
Much better PassMark score 1,632 vs 1,148 More than 40% better PassMark score
Much better geekbench 2 (32-bit) score 2,391 vs 1,895 More than 25% better geekbench 2 (32-bit) score
Much newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much better overclocked clock speed (Air) 3.75 GHz vs 3.36 GHz More than 10% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 4.49 GHz vs 2.2 GHz More than 2x better overclocked clock speed (Water)
Higher Maximum operating temperature 74.1 °C vs 73.3 °C Almost the same
Newer Jan, 2009 vs Jul, 2006 Release date over 2 years later
