Front view of Intel Pentium 4 521

Reasons to consider the
Intel Pentium 4 521

Report a correction
Much higher clock speed 2.8 GHz vs 1.6 GHz Around 75% higher clock speed
Much more l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Much better overclocked clock speed (Air) 3.72 GHz vs 3.16 GHz Around 20% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 4.28 GHz vs 2.69 GHz Around 60% better overclocked clock speed (Water)

Reasons to consider the
Intel Celeron E1200

Report a correction
Much newer manufacturing process 65 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More cores 2 vs 1 Twice as many cores; run more applications at once
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Significantly lower typical power consumption 52.81W vs 68.25W Around 25% lower typical power consumption
Much higher Maximum operating temperature 73.3 °C vs 67.7 °C Around 10% higher Maximum operating temperature
Significantly lower annual home energy cost 15.66 $/year vs 20.24 $/year Around 25% lower annual home energy cost
Significantly lower annual commercial energy cost 56.94 $/year vs 73.58 $/year Around 25% lower annual commercial energy cost
Newer Jan, 2008 vs Jul, 2005 Release date over 2 years later
