Overview

The Intel Xeon 3.6GHz (BX80546KG3600EA) is a server-class processor built on Intel's NetBurst microarchitecture, designed for Socket 604 workstation and server platforms. Running at 3.6GHz with an 800MHz front-side bus and 1MB of L2 cache, this chip was positioned as a high-performance option for compute-heavy tasks such as database hosting, scientific computation, and enterprise applications during its product cycle. The boxed version includes an Intel-designed cooling fan, ensuring adequate thermal management under standard operating conditions without requiring a third-party cooler.

While this processor is no longer competitive with modern multi-core CPUs in raw performance or power efficiency, it remains a relevant component for users who need to maintain, repair, or extend the life of existing Socket 604 server infrastructure. Finding a replacement processor for these legacy systems can be challenging, and having a boxed unit with an included cooler simplifies the process. For any new build or upgrade project, however, current-generation processors offer dramatically better performance per watt and multi-threaded capability.

Pros & Cons

👍 Pros

  • Server-grade Xeon architecture provides reliability designed for sustained, heavy workloads
  • Included cooling fan eliminates the need to source a compatible aftermarket cooler
  • 3.6GHz clock speed offers strong single-threaded performance for its generation
  • 1MB L2 cache helps reduce memory latency for frequently accessed data
  • 800MHz FSB provides solid data throughput between processor and chipset

👎 Cons

  • Socket 604 is a legacy platform with no path to modern motherboard or component upgrades
  • Power consumption and heat output are high relative to modern processors with comparable or greater performance
  • Single-core design cannot match the multitasking capability of current multi-core CPUs
  • Finding compatible Socket 604 motherboards and DDR2 memory may be difficult
  • Performance falls far behind current-generation processors for any modern workload

Frequently Asked Questions

This processor uses the 604-pin socket, which is found on server and workstation motherboards from its era.
Yes, Intel includes a cooling fan in the box, so no separate cooler purchase is necessary for standard operation.
The processor features an 800MHz front-side bus (FSB), which handles data transfer between the CPU and the system chipset.
As a server-class processor, it was designed for workstation tasks, server applications, and compute-intensive workloads on compatible legacy platforms.
No, this Xeon uses a Socket 604 interface, which is specific to older server and workstation motherboards. It is not compatible with current consumer or server platforms.
