What the Pentium 4 HT 570 is
The Intel Pentium 4 HT 570 is a 3.8 GHz single-core desktop processor with Hyper-Threading from November 2004. It runs one NetBurst Prescott core at 3.8 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 JM80547PG1121M in the 570J stepping. The cpu_list June 2004 date differs from the table November 2004 for the 570J, and the table date is used here.
The 570 tops the Prescott HT 5xx line with an 800 MT/s front side bus and a 19x multiplier at 1.20 V to 1.425 V. Intel positioned it as the fastest single-core NetBurst desktop before Cedar Mill 65 nm parts. The chip supports MMX, SSE, SSE2 and SSE3 with Hyper-Threading and Execute Disable on J steppings. No higher Prescott HT clock followed on LGA 775, since the 580 at 4 GHz was cancelled.
Top-bin heat defines the install. The 115 W envelope at 3.8 GHz needs a large tower cooler and strong case airflow, with noise rising under sustained load. That thermal ceiling is why dual-core Pentium D parts soon replaced single-core flagships for multitasking, offering two cores at similar power.
Socket and motherboard compatibility
The Pentium 4 HT 570 fits LGA 775 desktops with an 800 MT/s bus, 115 W delivery and Prescott HT J stepping support. It needs a land grid board with a BIOS that lists 570J parts. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Flagship DDR2 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 cannot carry the top bin without power delivery upgrades.
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. Regular dust cleaning keeps temperatures stable at 3.8 GHz.
Upgrade paths
On LGA 775 the 570 tops Prescott HT, so same generation upgrades stop here. Cedar Mill 661 parts at 3.6 GHz on 65 nm offer a cooler die shrink path where listed. Pentium D dual cores need new chipset support for two cores. The 570 lifts with the load plate, so swaps need no solder work.
