This guide is intended to help you identify the major Processor Technologies and their corresponding Processor Value Units (PVUs) per processor core. It helps clarify market inconsistencies across the major server brands when defining a "processor" or "N-Way".

Review the definitions and processor identification steps below and use the links to the right to view a list of Processor Technologies by Server Brand.

Processor Technology identification steps

Depending on the level of information known, there are two alternate ways to identify the number of PVUs per Core:

1. Method 1: Processor Vendor, Brand, Type and if applicable, Processor Model Number are known. [For example: IBM® POWER5™ Dual-core: 100 PVUs per core.] Use the Processor Value Units per Core Table.
2. Method 2: Processor Vendor, Brand, Type and if applicable, Processor Model Number are not known. However, server information is known.

For example

IBM® System x 3500: Intel® Xeon® Quad-Core with Processor Model Number in the range 5000 to 5499 at 50 PVUs per Core
