Here is a screenshot from a Dell PowerEdge R910 with four 2.27GHz Intel Xeon X7560 processors and 256GB of RAM. The Intel Xeon X7560 processor has eight cores, plus hyper-threading, for 16 logical cores per physical CPU. This gives you 64 logical processors for the entire machine. If you have deep pockets, this server can hold up to 1TB of RAM.
Here is a shot of CPU-Z, showing some more details about this processor. Notice that Core #0 of Processor #1 is running at 2657MHz, due to Intel Turbo Boost, which bumps up the clock speed of some cores when the rest of the cores are not that busy.
Unfortunately, I don’t have one of these servers to play with. One of my readers was kind enough to supply me with these screenshots. Thanks!
