Revit 2019 and IOMeter

This page contains two benchmarks that we have implemented for the first time into this CPU review. We are always looking for benchmarks that provide more of a real-world look at performance instead of just synthetic workloads and are excited about these test. That being said, we are always looking for feedback and suggestions as to our benchmark suite!

Revit 2019 – RFO Benchmark

RFO Benchmark is a community developed series of scripts that can be used to evaluate system-level performance in Revit, the popular building information modeling software from Autodesk used primarily by those in the Architecture fields.

This benchmark tests several different aspects of Revit functionality, which stress the system in different ways including the following subtests:

  • Update (converting a file to the Revit 2019 format from a previous version)
  • Model Creation 
  • Export (converting the document to a format for raster printing)
  • 3D Render 
  • Graphics (refreshing and rotating within the viewport of Revit)

RFO Benchmarks shows a clear advantage to the i9-9900K in typical usage scenarios for designers inside of Revit. Interestingly, the model creation workload, where users would spend most of their time in this application, is substantially worse on the higher core count processors.


One of the more overlooked aspects of single-threaded performance is disk throughput. As disks get faster and faster, a single application thread can struggle to achieve full bandwidth in some scenarios. 

In order to evaluate this, we are running a RAM disk of 1024MB on the host machine using the Softperfect RAM disk application, and then testing throughput in IOMeter with a 100% random 4K workload. Since a RAM disk is the fastest possible storage device, this will give us an idea of how IOPS scale with single-threaded processor performance.

Generation-to-generation improvement lies around 5-6% going from the 7700K to the 8700K, to the 9900K, with about a 15% improvement in IOPS going from the i9-7900X to the i9-9900K. 

Additionally, the AMD processors fair significantly worse in single-threaded maximum IOPS.
