I need to deploy a high performance number crunching service in Windows Azure. Are there any benchmarks out there about CPU performance in Azure?
I have found this thread mentioning it is a AMD Opteron 2347 HE Quad-Core 1.9GHZ but all Windows Azure pages mention it is a 1.6 GHz CPU. There are no other specs anywhere to be found. The guy from the forum post mentioned he somehow run CPU-Z in an Azure WebRole. I wonder how that could be replicated to get some up-to-date results.
If all you want to do is run CPU-Z then the simplest thing to do is to take one of the sample Azure web sites and when you deploy it make sure you’ve got remote desktop turned on. Once it’s deployed RDP into the instance, install and run any applications you like. When you’re done, delete the instance.
But there are a couple of things you’ll need to keep in mind. Just because the instance you deploy to has one type of CPU, that doesn’t mean that the next one you deploy to will be the same. While I’m sure MS got some bulk buying discounts on CPUs, Azure has been running long enough that some variation is bound to have crept in. Also just because there is a multi core CPU installed, it doesn’t mean you get access to all of it. Depending on the instance size you get more of the CPU dedicated to your instance (in the case of an extra small instance you don’t even get a whole core to yourself).
