I just got my Dell XPS 8930 and when I look at the system's properties, it says: Intel(R) Core(TM) i7-8700 CPU @ 3.20 GHz 3.19 GHz. That doesn't mean the CPU's speed will actually be 3.20 GHz, does it? It does go higher, right?
My Dell XPS 8700 from three years ago says: Intel(R) Core(TM) i7-4790 CPU @ 3.60 GHz 3.60 GHz. Even though 3.60 GHz is a higher number than 3.20 GHz, someone please tell me that the 8700 processor is not quicker than the 8930, right?
The frequency the CPU is clocked at does not necessarily determine how fast in executes programs. There are lots of other factors including the number of cores, size of cache, bus speed, etc. For example, the i7-8700 has 6 cores, the i7-4790 has 4. If you go to this site to see the benchmarks, https://www.cpubenchmark.net/high_end_cpus.html, you will see that the i7-8700 has a benchmark of 15.325 while the i7-4790 has a benchmark of 9.995. On the chart, look at the i9-7960X, it is clocked at 2.8 GHz, much slower than both your processors, and yet its benchmark is 26.407.
