Reasons to consider the
Intel Pentium 4 505J

Report a correction
Much higher clock speed 2.66 GHz vs 0.8 GHz More than 3.2x higher clock speed
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

Reasons to consider the
Intel Core M 5Y10

Report a correction
Much newer manufacturing process 14 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much lower typical power consumption 3.66W vs 68.25W 18.7x lower typical power consumption
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
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Newer Jul, 2014 vs Jan, 2005 Release date over 9 years later
More threads 4 vs 1 3 more threads
Much lower annual home energy cost 1.08 $/year vs 20.24 $/year 18.7x lower annual home energy cost
Much lower annual commercial energy cost 3.94 $/year vs 73.58 $/year 18.7x lower annual commercial energy cost
More cores 2 vs 1 Twice as many cores; run more applications at once
