The 1.8 Ghz speed can be considered a “guaranteed” all core speed it should be able to run at indefinitely at the standard 15w TDP (as long as the cooling system is in good shape).
4 Ghz is likely to be a single core turbo speed that can be run for a short period.
Is 1.8 GHz fast?
Well 1.8 GHz is fast for a human, but only middling fast for a computer. A single cycle at 1.8 GHz takes 555 picoseconds or about half a nanosecond. A nanosecond is a billionth of a second. In that time, light will travel about 6 inches.
What does 1.8 GHz processor mean?
It is typically measured in megahertz or gigahertz. One megahertz is equal to one million cycles per second, while one gigahertz equals one billion cycles per second. This means a 1.8 GHz processor has twice the clock speed of a 900 MHz processor.
Is 1.8 GHz good for a phone?
At the heart of your phone lies its processor, or CPU. Today’s fastest mobile processors have clock speeds ranging from 1.8 GHz to 2.2 GHz, though anything above 1 GHz should be acceptable.
Which is better 1.8 GHz or 2.5 Ghz?
One GHz is equal to 1 billion cycles and therefore 2.5 GHz is better than 1.8 GHz because it is able to complete 600 million more cycles (or processes) in the same amount of time thus leading to higher performance and greater efficiency.
What is a good processor speed?
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.
How many GHz is considered fast?
Again, more cache and higher clock speeds are better, but any CPU over 2.0GHz is fast enough to handle all the basic stuff, like playing music, surfing the Web and playing Web games, displaying online video, and managing e-mail.
