The Prescott core was introduced on Feb 2, 2004. This core is based on NetBurst microarchitecture.

New core features:

• 0.09 micron manufacturing process
• Increased L2 cache size up to 2 MB
• Extended Memory 64 technology (EM64T)
• Execute disable bit capability
• Virtualization technology
• SSE3

Identification of microprocessors with Prescott core:

• By part number: The part number contains 80546 (but not 80546K) or 80547. For example: RK80546PG0961M, JM80547RE088CN
• By CPU ID: First two digits of CPU identification number are "F3" or "F4". Please note that some Xeon processors had the same CPUIDs as Pentium 4 Prescott CPUs.

Celeron D microprocessors have modified Prescott core that includes 256 KB of level 2 cache memory. To distinguish this core from Pentium 4 Prescott core with 1MB L2 cache the Celeron D core is often called Prescott-256. Also, to distinguish between Prescott Pentium 4 cores with different sizes of L2 cache, the core with 2 MB L2 cache is often called Prescott-2M.
