How is "PassMark - CPU Mark" rating calculated on cpubenchmark.net
Question
I want to know the difference between the two ratings below. Part of the reason I'm asking is because I want to know who to choose wisely for server visualization and wisely balance speed with my budget by fully understanding the numbers. In virtualization, if I can get away with assigning fewer virtual cores to a VM, then it would seem that I could fit more VMs on a single server. I am mostly doing Apache web hosting and Vanrish Cache stuff.
Which graph do I use to figure out the best bang for the buck as in speed per core? Notice that you can also click "Price Performance" tab just above each of the graphs that rank the CPU Mark / $Price
The the number of threads per core a constant in these tests?
I assume the High End CPUs chart is testing multi-thread, so is this testing the speed per core or total processing power of all cores?
How do I effectively compare a 12 core processor to a 4 core using these graphs?
Anything other thought on what would help me choose wisely?

Assuming you mean virtualization rather than visualisation in the question it would be better to look at the VMMark results for a machine of similar spec. SPECint is another good benchmark to check. Passmark is going to test for things such as floating point performance and you're very unlikely to do any floating point operations in a virtual environment with commercial apps. (you will do a lot of floating point if it really is visualisation though or if you want to use it as a games PC too).

Thanks for catching that @andyadler. I did mean virtualization, typoed it I guess. Thank you for that tip... those are definitely the kind of things that I was looking for.
I can't seem to find an easy to read/view graph anywhere with the VMmark/SPECint specs you mentioned though???

As for your comments, I didn't realize that Windows 10 and family did such a good job of wasting idle CPU power. So much for my desktop six core CPU which is getting a little dated now.
So from your comments would you say that maybe the most telling graph for would be the Single Thread Performance chart?
