What the Mobile Pentium 4 3.06 is
The Intel Mobile Pentium 4 3.06 is a 3.06 GHz single-core mobile processor from June 2003. It runs one NetBurst Northwood core at 3.06 GHz with no turbo and no Hyper-Threading on this rating, so 1 core gives 1 thread. Cache is 512 KB of L2 on a 130 nm process. Power is rated at 70 W in a Socket 478 package. The cpu_list 1/2 threads and 3.067 GHz values differ from the table single thread and 3.06 GHz, and the table values are used here with the cpu_list precision kept in the quick field.
The 3.06 Mobile P4 tops the Mobile Pentium 4 Northwood line with a 533 MT/s front side bus and a 23x multiplier. Intel sold it at 417 dollars in June 2003. The chip supports MMX, SSE and SSE2. Mobile Pentium 4 HT 3.06 parts at the same clocks add Hyper-Threading for multitasking, so threads separate the bins at identical frequency.
Top mobile clocks without threads suited large notebooks for single-task speed. The 70 W envelope needs a flagship desktop-replacement cooler with wall power. That is why the 3.06 cost more than slower Mobile P4 parts despite sharing cache.
Socket and motherboard compatibility
The Mobile 3.06 fits Socket 478 desktop-replacement notebooks with Mobile P4 support. It needs a notebook Socket 478 board qualified for top mobile clocks. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Flagship large notebooks are the natural match. Maker lists decide fit by threads, since HT mobiles need different BIOS paths.
Memory, PCIe and cooling
Memory is DDR through the board chipset with notebook slots. The CPU has no controller.
A 533 MT/s bus ties the CPU to the chipset, while graphics hangs off the chipset. No PCIe lanes originate on the die. Cooling is the flagship notebook heat pipe for 70 W operation.
Upgrade paths
On Socket 478 the 3.06 tops Mobile P4 Northwood, so same socket upgrades stop here. HT 3.06 mobiles add threads at the same clocks. Pentium M parts on Socket 479 offer thin paths. The 3.06 removes with the socket mechanism, so swaps need no solder work.
