Product Overview

The AT80614004320AD Intel Xeon X5650 is a six-core processor with a base clock speed of 2.66GHz. It is built on a 32nm process and has a thermal design power of 95W. The processor is based on the Westmere-EP microarchitecture and is compatible with the LGA 1366 socket. It features a 1.5MB L2 cache and a 12MB L3 cache. The processor also supports Intel's QuickPath Interconnect (QPI) technology with a speed of 6.4 GT/s. This processor is suitable for use in servers and high-performance workstations.

Processor Architecture

The AT80614004320AD Intel Xeon X5650 processor is based on the Westmere-EP microarchitecture. This microarchitecture is a derivative of the Nehalem microarchitecture and was released in 2010. It is the successor to the earlier Bloomfield and Lynnfield microarchitectures.

Westmere-EP processors feature an improved on-die memory controller, which allows for faster memory access and lower memory latency. They also support Intel's Hyper-Threading technology, which allows for more efficient use of the processor's resources by enabling multiple threads to run simultaneously. The Westmere-EP microarchitecture also includes Intel's Advanced Vector Extensions (AVX) instruction set, which allows for faster and more efficient processing of floating-point calculations.

The Westmere-EP microarchitecture was used in the Xeon 5600 series processors, which are intended for use in servers and high-performance workstations. They are known for their high core count, high memory bandwidth and large cache.

Compatible Platforms

The AT80614004320AD Intel Xeon X5650 processor is compatible with the LGA 1366 socket. This socket, also known as Socket B, was introduced in 2008 and was used for Intel's Xeon, Core i7, and Core i7 Extreme Edition processors. LGA 1366 processors are designed to work with the X58, 5520 and 3420 chipsets. These chipsets support various features such as Intel's QuickPath Interconnect (QPI) technology, and support for DDR3 memory.

This processor is not compatible with newer socket types such as LGA 2011, LGA 2066, and LGA 3647 which are used for newer Intel processors. This means that if you wish to upgrade the processor in a system that currently uses a LGA 1366 socket, you will need to purchase a newer motherboard that supports the newer socket types.

It's also important to note that this specific processor is intended for use in servers and high-performance workstations, and may not be compatible with standard desktop motherboards. It's best to check the compatibility with the motherboard manufacturer before making a purchase.
