Pulled from a Compaq server as seen on the picture. Technically this CPU is the same as this Pentium III-S 1400. It only runs at a lower clock frequency.

The Pentium III-S is the fastest Pentium III processor around. It was made using a 130nm manufacturing process and has 512KB L2 cache. The normal Pentium III Tualatin without the -S only has 256KB L2 cache. > Read more

This type of Intel Pentium III processors performed very well. It was faster then the old Coppermine and even blew away the Intel Pentium 4 1,7GHz, which was much more expensive, in some benchmarks!

The '-S' mark defines the CPU as a server processor. These '-S' CPU's have 512KB L2 cache while the normal versions only have 256KB L2.

The Intel Pentium III-S 1400MHz is not common in desktop systems as it's a server CPU and it was quite expensive. A lot of people bought the AMD Athlon instead or got mislead by the higher GHz-mark of the Intel Pentium 4.

Enthusiasts tried to run these 'Tualatin'-CPU's in older Intel 440BX-chipset based boards and they succeeded! What an upgrade, getting your old Intel Pentium II or Celeron upgraded and beat the first generation P4 performance wise! The trick was to modify some of the hardware and use the correct Slotket (a convertor to use S370 CPU's in Slot1) which accepted FC-PGA2 CPU's. > Read more

Just like this Pentium III-S 1400 but with different sSpec number. The SL6BY version has a newer core compared to the SL5XL. > Read more
