Is your current processor not able to transfer heavy loads? Are you looking to switch to a dual processing workstation, instead? Well, then you have come to the right place.

Stores will overwhelm you with choices on what they think is the best dual processor. But I will make this choice easy for you. Ahead will be a comprehensive comparison between the two processors. That way you will be able to narrow it down to the processor that best suits your needs.

I will not only walk you through the performance differences between AMD Opteron vs Intel Xeon processors but I will also let you know which processor is best suited for the kind of job you need it to do. That way you won’t have to waste your money buying an advanced processor for performing simple tasks or vice versa, even.

The differences between AMD Opteron and Intel Xeon processors are as follows:

AMD Opteron Intel Xeon
Less expensive More expensive
Generally stays cooler Tends to heat up more quickly with use
Less efficient More efficient
iGPU only in the AMD APU series iGPU in almost all the Core i series
Clock speed may reach 5.0 GHz Clock speed can reach and surpass 5.0 GHz
Possesses symmetric multiprocessing capabilities of up to 128 cores Possesses symmetric multiprocessing capabilities of up to 28 cores

AMD Opteron Processor:

In the dual-processor market, AMD has several models of the Opteron CPU for dual-processor systems. They range from 2376, with a clock speed of 2.3GHz, to 2384, with a clock speed of 2.7GHz. All third-generation Opteron has an average CPU power of 75 watts and offers a 4x512KB L2 cache and 6 MB L3 cache.

Opteron dual processors have the following pros:

  • They support XOP instructions
  • Include Radeon Rx series GPU
  • Consume significantly lower power
  • Have approximately 79% more energy efficiency
  • Their system enjoys a longer battery life
  • They are cheaper and won’t put a dent in your wallet

On the other hand, Opteron has the following cons:

  • They run at a lower frequency, making them less efficient
  • Once bought, it is not possible to replace or upgrade it
  • They execute fewer threads

Intel Xeon Processor:

In the dual-processor market, Intel’s 5400 series of Xeon CPUs are considered to be the most popular processor by customers. Xeon 5400 series processors are available in different models. They range from the Quad Core E5405 model, which runs at 2 GHz speed and has a thermal design power of 80 watts, to the X5492 model, which runs at 3.4 GHz and has a thermal design power rating of 150 watts.

Intel Xeon processors have the following pros:

  • They have a speed advantage over other processors in the market
  • They provide maximum performance
  • Their microprocessor has a higher frequency
  • The CPU can easily be removed from the socket for any upgrade or replacement
  • They are clocked higher

It is also important to note that Intel Xeon processors have the following cons:

  • They lack certain instructions
  • They do not have on-chip graphics
  • They need considerably higher power
  • They consume greater battery life
  • They are not energy efficient
