All Xeon Models
By Gabriel Torres e Cássio Lima on January 21, 2008


Introduction

In 1998 Intel started including the name “Xeon” to label their processors targeted to the server and workstation market. These processors can access more RAM memory, can work on a multi-processing environment (i.e., motherboards with more than one CPU installed) and have a performance higher than their counterpart targeted to the end-user market.

The server and workstation versions of Pentium II and Pentium III were called Pentium II Xeon and Pentium III Xeon, respectively. So, while Pentium II and Pentium III were targeted to end users, Pentium II Xeon and Pentium III Xeon were targeted to servers and workstations.

With Pentium 4, Intel decided to call its server version as “Xeon” instead of “Pentium 4 Xeon.”

In the table below you can see the Intel CPUs targeted to end users and their counterparts targeted to the server and workstation market.

In this tutorial we will present the main technical features of all Xeon models released to date (Pentium II Xeon, Pentium III Xeon, Xeon and Xeon MP).

Pentium II Xeon

Intel released Pentium II Xeon in June 1998. This is an Intel 6th generation CPU, since it is based on the same architecture used by Pentium Pro.

The main difference between Pentium II Xeon and Pentium II is the clock rate on which the L2 memory cache is accessed. While Pentium II Xeon accesses its L2 memory cache using its internal clock rate (e.g., 400 MHz on a 400 MHz Pentium II Xeon), Pentium II accesses its L2 memory cache at half its internal clock rate (e.g., 200 MHz on a 400 MHz Pentium II).

The main technical features of Pentium II Xeon are:

Pentium II Xeon used a Pentium II-like slot, but it was incompatible, since it had 330 contacts (Pentium II slot had 220 contacts). This means that we couldn’t install a Pentium II Xeon on a Pentium II motherboard and vice-versa.

In the table below you see all Pentium II 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.

Pentium III Xeon

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:

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.

In 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.

Xeon

This CPU should be called Pentium 4 Xeon, but Intel opted for the name “Xeon”. As we mentioned before, Xeon is a Pentium 4 version targeted to servers and workstations. So it is a 7th generation Intel CPU. The models from Xeon series we’ve seen so far used Intel’s 6th generation architecture, the same used by Pentium Pro.

Figure 3: Xeon processor.

The difference between Xeon and Xeon MP is that the first only allows symmetric multiprocessing up to two CPUs, while the second allows symmetric multiprocessing with four or more CPUs. Actually when it was first released Xeon processor was called “Xeon DP” (meaning “Dual Processing”).

Xeon processors have 8 KB L1 data cache (16 KB on models that have the 64-bit EM64T technology) and a 150 KB L1 trace execution cache. L2 memory cache can be of 512 KB, 1 MB or 2 MB and some models have a L3 memory cache of 1 MB, 2 MB, 4 MB or 8 MB.

In the table below we listed all Xeon models released to date.

Xeon MP

As we explained, the difference between Xeon MP and Xeon is the number of supported CPUs for SMP (symmetric multiprocessing): Xeon supports SMP up to two CPUs on the same motherboard and Xeon MP supports up to four CPUs per bus.

It is possible to build servers with more than four Xeon MP CPUs on the same motherboard. In this case the processors should be tied in groups of four – since they only support up to four processors per bus. For example, on a server with eight Xeon MP processors, the first four will be connected to the same bus and the other four will be connected to another bus. The connection between the busses should be done by the chipset.

The main technical features of Xeon MP are:

In the table below we listed all Xeon MP models released to date.

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.

Xeon 50xx, 70xx and 71xx Models (Dual-Core)

Dual-core technology puts two complete CPUs into the same package. Since dual-core Xeon CPUs 50xx, 70xx and 71xx models also have Hyper-Threading technology – which simulates two CPUs per core – the operating system recognizes each dual-core Xeon processor as four CPUs. So, on a server using two dual-core Xeon CPUs the operating system will recognize eight CPUs (four cores, two per processor, and two logic processors per core).

All dual-core Xeon processors 50xx, 70xx and 71xx models have the following features:

In the table below we listed all dual-core Xeon 50xx, 70xx and 71xx models released to date. 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.

Xeon 30xx, 51xx and 72xx Models (Dual-Core)

Xeon 30xx, 51xx and 72xx processors are based on the latest Intel microarchitecture, Core, the same used by Core 2 Duo processors. These CPUs were known in the past as Woodcrest, Intel codename for this CPU generation. If you want to learn more about the new Core microarchitecture, read our tutorial on this subject.

Keep in mind that dual-core Xeon from the series described on the previuos page (50xx, 70xx and 71xx) are based on Pentium 4 microarchitecture (NetBurst) carrying Hyper-Threading technology, which is not available on Core microarchitecture.

All Xeon 30xx, 51xx and 72xx series have the following features:

Below you can find all Xeon 30xx, 51xx and 72xx models released to date. 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.

Xeon 31xx and 52xx Models (Dual-Core)

Xeon 31xx and 52xx processors, like 30xx, 51xx and 72xx models, are based on Core Microarchitecture, the same used by Core 2 Duo processors (to learn more about Core microarchitecture read our tutorial on this subject). The main difference between these models is the manufacturing process employed. While 30xx, 51xx and 72xx models use the 65 nm manufacturing process, 31xx and 52xx models use the new 45 nm process. This manufacturing process is also known by its codename Penryn. To learn more about this manufacturing process, read our Details on Intel’s Forthcoming 45 nm Manufacturing Technology and Penryn Core New Features articles. Notice that Penryn is the codename of the manufacturing process, not of the processor. The codename of Xeon 31xx and 52xx processors is Wolfdale.

There are other differences between Xeon 31xx and 52xx and the other Xeon CPUs based on Core microarchitecture described in the previous page besides the manufacturing process: the new SSE4 instruction set and a larger L2 memory cache.

All Xeon 31xx and 52xx processors have the following features:

Xeon 32xx, 53xx and 73xx Models (Quad-Core, 65nm)

Xeon 32xx, 53xx and 73xx processors are based on Core microarchitecture and have four processing cores. These four cores are obtained from two dual-core dies. Because of that the L2 memory cache from these processors isn’t shared between all cores: cores 1 and 2 share the same L2 cache, while cores 3 and 4 share another L2 cache. The L2 memory cache size announced is the total amount of L2 cache available (i.e., the sum of the two caches). Read our Intel Quad-Core Overview and Roadmap article for a more detailed explanation on the architecture used by these CPUs.
