The Northwood core was introduced on August 27, 2001. This core is based on NetBurst microarchitecture.
New core features:
0.13 micron manufacturing process
Lower power consumption
Increased bus speed up to 800 MHz (200 Mhz QDR)
Increased L2 cache size to 512 KB
Hyper-Threading technology
Identification of microprocessors with Northwood core:
By part number: Part number contains 80532 (but not 80532K) and
does not end with "2M", "F", "FS" or "MS".
For example: RH80532GC049512, BX80532PC1800D
By CPU ID: First two digits of CPU identification number are "F2".
Please note that Xeon processors with Prestonia and Gallatin cores
had the same CPUIDs as Pentium 4 Northwood CPUs.
Desktop and mobile Celeron microprocessors have modified Northwood
cores that include 128 KB or 256 KB of level 2 cache memory
respectively. To distinguish them from Pentium 4 Northwood core with
512 KB L2 cache the Celeron cores are often called Northwood-128 and
Northwood-256.
their are two variants of the Micro-FCPGA 478 moblie flip chip pin grind array processors not one the standard desktop p4 478 pin type and a so called 479 p4 pin type (actually has 478 pins but different layout than standard desktop p4 layout.)both are listed as Micro-FCPGA now on Intels spec finder (they use to list by pin type-count. noiw they just made it more confusing if I've got a Micro-FCPGA 478 processor and it dies and I buy a replacement but its a 479 pin Micro-FCPGA processor its not going into that socket and will bend or snap off one pin. a pin has been relocated on the 479 pin cpu. but a 478 cpu will fit a 479 socket not sure if it will work even because a 479 pin socket is a complete squared socket (extra pin holes)all pin hole row finished. makes a big difference when buy or selling your moblie P4 cpu's in 478 Micro FCPGA to be correctly identified it might actually be a 479. if you could tell me how to get a good sharp picture of the pin difference, I would upload a picture of the difference but I've only got a digtal camera and every time I try it comes out bulry.
