Intel Itanium 9030

Report a correction
Much more l2 cache 8 MB vs 0.5 MB 16x more l2 cache; more data can be stored in the l2 cache for quick access later
Much more l2 cache per core 4 MB/core vs 0.25 MB/core 16x more l2 cache per core
Supports more CPUs in SMP configuration 4 vs 1 3 supports more CPUs in SMP configuration
Much more l3 cache per core 4 MB/core vs 2 MB/core 2x more l3 cache per core
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

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 higher clock speed 2.66 GHz vs 1.6 GHz More than 65% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much lower typical power consumption 28.44W vs 84.5W 3x lower typical power consumption
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
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Newer Jan, 2010 vs Jul, 2006 Release date over 3 years later
Much lower annual home energy cost 8.43 $/year vs 25.05 $/year 3x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 91.1 $/year 3x lower annual commercial energy cost
More threads 4 vs 2 Twice as many threads
