System on Module Performance

Question

It is early days for the System on Module (SOM), and we are eargerly waiting for our first developers kit, but perhaps someone has had the fortune of testing the SOM already, and could give us an idea of the performance level we can excpect from it? In particular we are interested in how it compares to the cFP-2220 on numeric operations, but I do not expect anyone to have done a 1-1 comparison between those.
We have some extremely heavy number crunching to do (tomographic analysis), which takes the poor old cFP-2220 several hours to complete (another low-power SBC alternative in-house is even 10 times slower than that(!)). A modern desktop computer is able to finish the same job in a couple of minutes. I do not expect the SOM to get anywhere close to the desktop PC, but any rough idea on where in-between it might land?

Answer 1

The Zynq-7020 processor on the SOM is also used on the cRIO-9068 CompactRIO controller.  When that controller was released, we published some bechmarks relative to the cRIO-9074, which uses a 400MHz PPC processor similar to the cFP-2220.  Those benchmarks can be observed here:
NI cRIO-9068: Performance and Throughput Benchmarks
As a general guideline, we estimate typical applications will see roughly a 4x performance improvement on the cRIO-9068 (with Zynq processor) compared to previous generation systems with 400MHz PPC processors.
You may not see the exact same improvements, but expect similar results from your upgrade from Compact FieldPoint to the SOM. Unfortunately, we don't have a published benchmark on raw computational power; the benchmarks published demonstrate system performance improvements due to faster processing and other system-level improvements (such as faster DMA engines, faster memory access, improved Ethernet speed, more efficient OS thread scheduler, etc.)
