Any way you measure it, the average 2 vCPU VM performs nearly the same as it did 5 years ago. Thanks to microarchitecture improvements, the cores provide 9% higher system level performance as measured by SPECint_rate. While the number of processor cores has increased by 75% in the past 5 years allowing 75% more VDI VMs per server, the clock speed of each core is actually down 11%.
The table below compares a typical VDI server from 2012 (the first full year that the Hardware Accelerator was available) to typical VDI server in 2016. New servers increasing core counts but not individual VM performance. How do these more powerful servers affect the value of PCoIP protocol offload provided by PCoIP Hardware Accelerator? Moore’s law continues to provide ever more powerful server processors that provide the ability to support more virtual desktops per server and improve the cost per desktop accordingly.
Do powerful new VDI servers still benefit from hardware acceleration?
