Our take on the Intel Pentium 4 SL6WS Processor

The Intel Pentium 4 SL6WS is a single-core desktop processor running at 2.60 GHz on a 400 MHz front-side bus, with 512 KB of L2 cache and a Socket PGA478 interface. It is a Northwood-generation part from the early 2000s, built for older socket 478 motherboards and the DDR memory systems that go with them. Its value today is as a replacement or spare for a legacy machine, not as an upgrade over anything modern. Compared with later Pentium 4 revisions, it has the slower 400 MHz bus and no Hyper-Threading, so it trails the 800 MHz Prescott and Northwood chips in multitasking and memory throughput.

Pros
  • Drops into existing socket 478 boards without a platform change
  • 512 KB L2 cache is generous for its generation
  • Runs cooler and draws less power than later Prescott Pentium 4 chips
  • Widely supported by early-2000s chipsets and BIOSes
  • Simple single-core design with no Hyper-Threading quirks
Cons
  • Single core with no Hyper-Threading limits multitasking
  • 400 MHz bus is the slowest Pentium 4 front-side bus
  • Far slower than any current processor for everyday tasks
  • Only suits socket 478 boards, which are long out of production
  • No 64-bit support, so it cannot run modern 64-bit operating systems

Questions and answers

Will this work in my socket 478 motherboard?
It uses the PGA478 socket, so it fits boards that accept 400 MHz bus Pentium 4 chips. Check your board's CPU support list, since some 478 boards only officially support 533 or 800 MHz bus parts.
Does it support Hyper-Threading?
No. This is a single-core, single-thread part. Hyper-Threading arrived on later Pentium 4 models with faster bus speeds.
Can it run a modern 64-bit operating system?
No. The chip is 32-bit only, so it is limited to 32-bit operating systems such as 32-bit Windows XP or a 32-bit Linux distribution.
What cooler does it need?
A standard socket 478 heatsink and fan. The retail cooler for 2.6 GHz Northwood parts is adequate; the processor does not ship with one here.
Is it worth it over a faster Pentium 4?
Only if your board is limited to a 400 MHz bus. If the board supports 533 or 800 MHz bus chips, a faster Northwood will give noticeably better performance.
Where is the Intel Pentium 4 SL6WS Processor cheapest?
At Tech Network Supply LLC, for $50.75, as of our latest check.
