Intel Celeron D family is a new brand name for desktop
Celeron processors. The fastest
Celeron CPUs were based on 0.13 micron Northwood core. The Celeron D
processors are based on the next two Pentium 4 cores - 0.09 micron
Prescott core and 0.065 micron Cedar Mill core.
There are three different versions of Celeron D processors based on
Prescott core:
- Celeron D in 478-pin micro FC-PGA package for socket 478
motherboards. These processors include basic features of Prescott
core, and have neither Execute Disable bit capability, nor
64-bit execution mode.
- First Celeron D processors in 775-land FC-LGA package offered
Execute Disable bit capability.
- Newer Celeron D CPUs in 775-land package include both Execute
Disable bit capability and 64-bit mode.
Overall, Prescott Celeron D microprocessors have a few improvements
over Northwood Celeron processors - 33% faster Front-Side Bus
frequency, twice larger level 2 cache, and 64-bit mode in some
Celeron D Prescott CPUs.
64-bit mode is also included in Celeron D microprocessors based on
Cedar Mill core. Besides that these CPUs also have larger level 2
cache - 512 KB as opposed to 256 KB on Prescott Celeron D processors.
