Front view of Intel Pentium J2900

Reasons to consider the
Intel Pentium J2900

Report a correction
Much newer manufacturing process 22 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
More cores 4 vs 1 3 more cores; run more applications at once
More threads 4 vs 1 3 more threads
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
Much lower typical power consumption 8.13W vs 68.25W 8.4x lower typical power consumption
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much lower annual commercial energy cost 8.76 $/year vs 73.58 $/year 8.4x lower annual commercial energy cost
Much lower annual home energy cost 2.41 $/year vs 20.24 $/year 8.4x lower annual home energy cost
