Front view of Intel Pentium E2180

Reasons to consider the
Intel Pentium E2180

Report a correction
Much newer manufacturing process 65 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 2 GHz vs 0.55 GHz Around 3.8x higher clock speed
Significantly more l2 cache 1 MB vs 0.13 MB Around 7.8x more l2 cache; more data can be stored in the l2 cache for quick access later
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
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 more l2 cache per core 0.5 MB/core vs 0.13 MB/core More than 3.8x more l2 cache per core
Significantly better overclocked clock speed (Air) 3.13 GHz vs 2.27 GHz Around 40% better overclocked clock speed (Air)
More cores 2 vs 1 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 3.65 GHz vs 2 GHz Around 85% better overclocked clock speed (Water)
