What the Mobile Pentium 4 HT 552 is
The Intel Mobile Pentium 4 HT 552 is a 3.467 GHz mobile single core from January 2005. It runs one NetBurst core at 3.467 GHz with Hyper-Threading, so 1 core gives 2 threads. Cache is 1 MB of L2 on a 90 nm process. Power is rated at 88 W on Socket 478.
The 552 served desktop-replacement Socket 478 notebooks on a 533 MT/s bus with a 26x multiplier. The table gives no separate TDP against 88 W in cpu_list, and 88 W is used here. It exists because large notebooks wanted Pentium 4 threads with 1 MB of cache at mobile voltages.
Socket and motherboard compatibility
The 552 fits Socket 478 notebooks with DDR memory and a BIOS that lists mobile Prescott parts. It needs a desktop-replacement chassis qualified for 88 W. Display comes from the notebook board graphics. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR through the board chipset.
A 533 MT/s front side bus ties the CPU to the chipset. Board graphics hang off the chipset.
Cooling is the notebook vendor heat pipe assembly for an 88 W desktop-replacement chassis.
Upgrade paths
On Socket 478 the upgrade stays within mobile Prescott, as the 552 tops the 5xx mobile line. The Intel Celeron D 350 at 3.2 GHz drops to a desktop part without threads. Beyond Socket 478 a move to a newer mobile platform needs a new board.
