Front view of Intel J3060

Reasons to consider the
Intel J3060

Report a correction
Much newer manufacturing process 14 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly 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
Significantly lower typical power consumption 4.88W vs 52.81W 10.8x lower typical power consumption
Much better performance per watt 7.06 pt/W vs 0.74 pt/W Around 9.5x better performance per watt
Significantly more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Newer Jan, 2016 vs Dec, 2013 Release date over 2 years later
Significantly lower annual commercial energy cost 5.26 $/year vs 56.94 $/year 10.8x lower annual commercial energy cost
Significantly lower annual home energy cost 1.45 $/year vs 15.66 $/year 10.8x lower annual home energy cost
