Front view of Intel Xeon X3430

Reasons to consider the
Intel Xeon X3430

Report a correction
Significantly higher clock speed 2.4 GHz vs 1.33 GHz More than 80% higher clock speed
Higher turbo clock speed 2.8 GHz vs 2.4 GHz More than 15% higher turbo clock speed
More l3 cache 8 MB vs 4 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Much better overclocked clock speed (Air) 3.7 GHz vs 1.33 GHz More than 2.8x better overclocked clock speed (Air)
More cores 4 vs 2 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 4.14 GHz vs 1.33 GHz More than 3x better overclocked clock speed (Water)

Report a correction
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Newer manufacturing process 32 nms vs 45 nms A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Significantly lower typical power consumption 14.63W vs 77.19W 5.3x lower typical power consumption
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Significantly lower annual commercial energy cost 15.77 $/year vs 83.22 $/year 5.3x lower annual commercial energy cost
Significantly lower annual home energy cost 4.34 $/year vs 22.89 $/year 5.3x lower annual home energy cost
Marginally newer Aug, 2010 vs Sep, 2009 Release date 10 months later
