Hard no. Amazon EFA can barely come close to a dated HPC interconnect from the lower part of the top500 (when it comes to running code that does use the network, e.g. molecular dynamics or CFD), Azure does offer Cray XC or CS (https://azure.microsoft.com/en-us/solutions/high-performance...) which can/will be set up as proper HPC machines with fast interconnects, but I doubt these can be readily rented in the 100s of PFlops size.
In fact, _better_ than Chrome for most websites (exceptions perhaps google's). I used to struggle with Chrome/Chromium hang and chew on CPU cores, crawl to a halt, crash, or just simply run out of memory or a regular basis. Switched to Firefox ~67-69 and such issues are completely gone. I still have significant CPU usage from background tabs occasionally even in Firefox, but the rest of the issues are all nearly inexistent (even though I have on average 30+ tabs open).
Check these talks from the recent ISC EXACOMM workshop if you want to see why HPC machines and HPC computing are an entirely different league compared to traditional data center computing: https://www.youtube.com/watch?v=9PPGvqvWW8s&list=WL&index=9&... https://www.youtube.com/watch?v=q4LkF33YMJ4&list=WL&index=7
