All Xeon Models | Hardware Secrets

Intel released Pentium III Xeon on March 1999. It is also a 6th generation Intel processor, like Pentium III and Pentium II, since it is based on the same architecture used by Pentium Pro.

Figure 2: Pentium III Xeon processor.

The main technical features of Pentium II Xeon are:

16 KB instruction L1 memory cache and 16 KB data L1 memory cache.
512 KB, 1 MB or 2 MB L2 memory cache accessed at the same internal clock rate as the CPU.
100 MHz or 133 MHz external bus.
Access to up 64 GB RAM memory.
Symmetric multiprocessing (SMP) up to four CPUs (models with 2 MB L2 cache allowed SMP up to eight CPUs).
The CPU was installed in a cartridge called SECC (Single Edge Contact Cartridge) and connected to the motherboard thru a 330-contact connector called slot 2.
SSE instruction set.
0.25 µm (codename “Tanner”) or 0.18 µm (codename “Cascades”) manufacturing process.

Pentium III Xeon used the same slot type as Pentium II Xeon and could use the same motherboard originally designed for Pentium II Xeon (sometimes a BIOS upgrade was necessary), if the motherboard was capable of providing the external clock rate required by the CPU. This slot was incompatible with the slot used by Pentium II and the first Pentium III models (slot 1). This means that you couldn’t install a Pentium III Xeon on Pentium III motherboards and vice-versa.

On the table below you see all Pentium III Xeon models that were released. TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation, i.e. the CPU cooler must be able to dissipate at least this amount of heat.
