To complete disclaimer: "Do not compare CPUs by process technology or frequency. If you need to compare, use benchmarks that show performance and efficiency and even better, do it on your own application because the results vary between applications."

How do I compare CPUs on my own application without buying them? Is there some kind of daily-billed cloud computing service where I can choose any CPU and run my app on it?

  Just use benchmarks that are published online that compare existing application on various hardware. Process node is basically meaningless for the user.

    Previously published benchmarks may or may not have the current spectre/meltdown patch applied.

      It will depend on the user. Gamers, for example, will not be interested in having their systems limping to get a bit of extra security when they already pay through the nose to get extra couple of percent of performance.

        They might not have a choice.

    Laptops also frequently have significant performance variations, even with the same chip, due to differing cooling solutions.

If you look at EC2 instance types [1], about 1/2 of them have a specific CPU related to them. Same thing with Microsoft's Azure instances [2]. There are a limited number of cpus available - they typically are xenons or AMD equivalents, so if you want data on consumer CPUS, the best you can do is try your app out in the cloud and then look at published benchmarks and try to estimate what your expected performance should be. ___ 1. https://aws.amazon.com/ec2/instance-types/ https://aws.amazon.com/ec2/instance-types/ 2. https://azure.microsoft.com/en-us/pricing/details/virtual-machines/series/ https://azure.microsoft.com/en-us/pricing/details/virtual-ma...

    Careful about the clouds, performance under virtualization has many pitfalls and in some workloads is very much unlike bare metal. The correlation of bare-metal cores vs cloud vCPUs is very much nonlinear.
