Laptops, which one is faster, CPU Speed 3.40 GHz or 1.00 GHz?
I get the feeling that the lower number means it'll run faster but I might be wrong so I'm asking.

A clock speed of 3.5 GHz to 4.0 GHz is generally considered a good clock speed for gaming but it's more important to have good single-thread performance. This means that your CPU does a good job of understanding and completing single tasks. This is not to be confused with having a single-core processor.

If all other factors are equal than the higher clock speed would be faster.
The problem of course is that most of the time everything else isn't equal, and therefore clock speed is not an accurate gauge of whether one CPU is faster than another.
Unless you are comparing two processors within the same family and generation, there are other factors at play. In general, newer CPUs have been pushing to be more efficient and do more work with less power. A 3.4 GHz processor from 5 years ago is not as fast as a 3.4 GHz processor made last year for this exact reason.
If you want to get a better idea of how a CPU performs, you can look up the model for reviews on sites like Notebookcheck where they will often compare its performance in various benchmarks to give an idea of how it stacks up to other similar devices.

Depends on the cpu, GHz only matters for the same line of cpu and within the same generation. For instance a 4 ghz intel cpu from 10th gen is much faster than a 4ghz from the 2nd gen intel cpu.
This is called instructions per clock or IPC.

Generally speaking, GHz in computers is like mph or kph in cars. GHz determines the speed of the processor. It's more complicated than that however with multi-core processors that act as one but in general, GHz is a good measure of processing speed.

it all depends on the cores, a quad core CPU running at 1.00Ghz is actually faster than a dual core running at 3.40Ghz
However a dual core running at 3.40ghz is obviously faster than a dual core running at 1.00Ghz.

you are 180 degrees wrong -- higher speed is faster, other things equal

The faster your laptop is rated the better it's going to work. But if you get a laptop that is clocked off the front bus speed at 1.8. and you get a laptop that is clocked at 3.5 GHz. Rear bus speed but only delivers 800 MHz on the front bus.
Then the slower processor might appear to be faster for some duties. But as a general rule you always want the bigger faster processor. Because you have a heat issue
When processors get hot they lose speed that leads to bottlenecking and then all the components start to get hot and things start to get even slower.
It's far better to have a high-speed processor with a monster sized fan and block. Then it is to have a little processor that's a bit faster doing light duties.

The number is the speed at which your CPY runs. Think of it as a car going MPH. Which would be faster? A car going 3.4 MPH or a car going 1 MPH? Of course the 3.4 MPH is faster.

For processors of the same kind, a higher number of GHz indicates a higher speed.

Hertz is defined as the number of cycles per second. Which is faster 3 billion cycles per second or 1 billion cycles per second. Hint: it’s not 1.
You could just compare prices. If you go for a bigger hertz, you pay more so than tells you that a bigger hertz is faster.
