I noticed that HP computers labels their CPU like this: Intel(R) Core(TM) i7-3960X six-core processor [3.3GHz, Shared 15MB Cache]
What does Shared cache mean? Are the HP computer CPU's made differently than the CPUs from Intel?
Some friends told me to try this free software, and I wanted to know your opinion about it?
