Intel Celeron B830

Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly more l2 cache 1 MB vs 0.25 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much lower typical power consumption 28.44W vs 68.25W 2.4x lower typical power consumption
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
More cores 2 vs 1 Twice as many cores; run more applications at once
Much lower annual home energy cost 8.43 $/year vs 20.24 $/year 2.4x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 73.58 $/year 2.4x lower annual commercial energy cost
