Reasons to consider the
AMD Opteron 3250 HE

Report a correction
Much more l2 cache 4 MB vs 0.5 MB 8x 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
More cores 4 vs 2 Twice as many cores; run more applications at once
Lower typical power consumption 36.56W vs 44.69W Around 20% lower typical power consumption
Lower annual commercial energy cost 39.42 $/year vs 48.18 $/year Around 20% lower annual commercial energy cost
Lower annual home energy cost 10.84 $/year vs 13.25 $/year Around 20% lower annual home energy cost
