Here is my small test results after running CPU intensive process on Mac Pro.
My main use cases are running data analysis and plotting figures mostly using R-studio IDE. This does not put this machine to any stress at all. It is way overpowered for that purpose. The real test comes with the software to analyze genomic data. I have plenty of raw data from Microbiome sequencing reads. This is an ideal data to put the CPU under stress for longer period of time.
I happened to have Soil microbiome dataset that I needed to analyze for protein content. I decided to use https://github.com/bbuchfink/diamond for that purpose. It is faster than NCBI Blast alignment software and practical enough to be used on workstation. Overall, the file input size is around 11 GB gzipped. I decided to use 9 CPUs out of 12-cores in order to spare some CPU cores for other side tasks such as web-surfing and playing music.
Here are some stats from the Intel Power Gadget software sampled for 13 minutes (https://software.intel.com/en-us/articles/intel-power-gadget) which I saved on CSV file attached in this post.
If you just want to get gist of it, the CPU core temperature ranged from 92 – 70 degree celsius! (197.6 – 158 degree F). Now that is a very hot temperature. The 3 huge intake fans in the front were at 500 RPM. Average CPU (Xeon W-3235 3.3 GHz 12-core) power usage was at 162.87 Watt and DRAM (96 GB = (8GB*4)+(32GB*2)) power usage was at 41.75 Watt. The thermal output for Mac Pro as per Apple website is here : https://support.apple.com/en-us/HT201796
The ambient temperature using my infrared gun was 29-31º C in top-front side and 43-45 º C in the top back. I could feel the heat emanating under my desk. This makes sense since CPU is located on the top section. For the reference, the ambient temperature was 26.67 ºC (80ºF) in the room.
The sound level as measured by the 4th gen Apple watch is around 34 dB. I can barely hear it behind the background noise in my home. The process has been running for close to 24 hours and the temperature have stayed at this level.
I am not sure what can I say about the longevity of this machine based on this informal test. It seems to be really silent and I love silent machines.
