Front view of Intel J3455

Reasons to consider the
Intel J3455

Report a correction
Much newer manufacturing process 14 nm vs 250 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly higher clock speed 1.5 GHz vs 0.53 GHz More than 2.8x higher clock speed
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
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
Newer Jul, 2016 vs Sep, 1999 Release date over 17 years later
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Lower typical power consumption 8.13W vs 24.13W 3x lower typical power consumption
More cores 4 vs 1 3 more cores; run more applications at once
More threads 4 vs 1 3 more threads
Lower annual home energy cost 2.41 $/year vs 7.15 $/year 3x lower annual home energy cost
Lower annual commercial energy cost 8.76 $/year vs 26.02 $/year 3x lower annual commercial energy cost
