What the Pentium 4 HT 560 is

The Intel Pentium 4 HT 560 is a 3.6 GHz single-core desktop processor with Hyper-Threading from June 2004. It runs one NetBurst Prescott core at 3.6 GHz with no turbo, so 1 core gives 2 threads. Cache is 1 MB of L2 on a 90 nm process. Power is rated at 115 W in an LGA 775 package with part numbers JM80547PG1041M.

The 560 uses an 800 MT/s front side bus with an 18x multiplier at 1.20 V to 1.425 V. Intel sold it at 637 dollars in June 2004. The chip supports MMX, SSE, SSE2 and SSE3 with Hyper-Threading. A 560J shares clocks with Execute Disable support from October 2004. No Socket 478 version exists at 3.6 GHz in the opened tables, so LGA 775 boards are mandatory for this rating. The cpu_list Socket 478 3.6E entry lacks table support and is skipped separately.

Top clocks on Prescott need strong cooling. The 115 W envelope at 3.6 GHz needs a large heatsink and good case airflow, with fan noise rising under load. That heat is why later Cedar Mill 65 nm parts at the same clocks run cooler with a die shrink.

Socket and motherboard compatibility

The Pentium 4 HT 560 fits LGA 775 desktops with an 800 MT/s bus, 115 W delivery and Prescott HT support. It needs a land grid board qualified for top-bin power. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Performance towers with PCIe graphics are the natural match. Intel 925X boards accept the chip with a 115 W cooler. Boards limited to 84 W parts need a power check before fitting the 115 W bin.

Memory, PCIe and cooling

Memory is DDR or DDR2 through the board chipset. The board sets speed and capacity.

An 800 MT/s bus ties the CPU to the chipset, while PCIe x16 carries graphics. No PCIe lanes originate on the die. Cooling uses the LGA 775 plate with a 115 W heatsink and strong airflow. Dust control matters at high power.

Upgrade paths

On LGA 775 the step is the Pentium 4 HT 570 at 3.8 GHz at the same power class. The 560J adds Execute Disable at the same clocks. Beyond NetBurst a move to Pentium D dual cores needs new chipset support. The 560 lifts with the load plate, so swaps need no solder work.

Frequently asked questions
