Differences What are the advantages of each
| |||||||
| Supports more CPUs in SMP configuration | 2 | vs | 1 | Twice as many CPUs in SMP configuration | |||
|---|---|---|---|---|---|---|---|
| |||||||
| Much newer manufacturing process | 32 nm | vs | 180 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 | |||
| Has a NX bit | Yes | vs | No | Somewhat common; Prevents a common class of security exploits | |||
| Higher clock speed | 1.1 GHz | vs | 0.8 GHz | Around 40% higher clock speed | |||
| Newer | Jun, 2011 | vs | Dec, 1999 | Release date over 11 years later | |||
| 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 | |||
