Top-End CPU Performance With the Intel Xeon X5690

The Intel Xeon X5690 microprocessor is Intel's flagship 5000-series six-core CPU. Based on their 32 nm Westmere-EP microarchitecture, the Xeon X5690 is the most powerful central processor available for motherboards that utilize the LGA 1366 processor socket. Still powerful enough to compete with recent high-end processors, the X5690 is available an excellent way of revitalizing an older motherboard and is available at a fraction of the cost of more recent cards on eBay.

Will the Xeon X5690 work in my computer?

The Xeon X5690 is an Intel CPU and will only fit in motherboards that are manufactured to accept Intel CPUs of its size. The X5690, like all other CPUs, will function only when placed in a matching socket, which in this case is the LGA 1366 socket. If you're unsure whether the X5690 is compatible with your motherboard, you can find out what CPU your computer is currently using by finding it in the "Systems" section of the Windows Control Panel. The CPU model can then be found on the Intel website, where the socket will be listed. Alternatively, you can consult the manufacturer of your motherboard.

How does the X5690 compare to other more recent CPUs?

While difficult to quantify, the Xeon X5690 maintains an aggregate benchmark score of 8945 on the PassMark website, which gathers benchmark data from a wide variety of systems using a proprietary software program that runs the CPU and other components through a series of relevant tests. A score of 8945 is classified as a high-end CPU, and it's competitive with many other, much more expensive processing units.

Are there any advantages to buying an X5690 on eBay?

Yes. A gently used Xenon X5690 purchased on eBay is generally just as reliable as one purchased brand new and usually considerably cheaper. Many used CPUs are tested extensively before being placed on the market. Additionally, if you intend to personally install your new Xenon X5690, a number of useful kits are available that include both the CPU and everything that you'll need (such as thermal paste, properly sized hex wrench, etc.) to properly install it.

What are the Intel Xeon X5690's technical specifications?

The Xeon X5690 is the absolute pinnacle of performance in its class. There simply isn't a more powerful option available if your motherboard utilizes the LGA 1366 socket. The processor offers remarkable performance and is competitive with many more recent CPUs. Technical specifications include:

  • Cores: Six
  • Frequency: 3.47 GHz
  • Cache: 12 MB SmartCache
  • Socket: LGA 1366
  • Thermal Design Power: 130 Watts
