[SOLVED] CPU

Why is a new Intel Core i5-12500 - Core i5 12th Gen Alder Lake 6-Core 3.0 GHz LGA 1700 65W Intel UHD Graphics 770 Desktop Processor
running at 3.0 GHz when my 11 year old i3-2120 2 core, 4 thread runs at 3.30 GHz?

I'm guessing that the number of cores/threads has something to do with it?

because it a newer gen. don't need as much ghz

The i3-2120 has 500 million transistors while the i5-12xxx has 1.7 billion transistors.

Having more transistors means you can have a lot of new features and functions, larger cache memory, higher number of executions and faster speed.

SWEET!!! MAKES SENSE!! THNX!

GHz is only one part of the situation.

As far back as 2005, we had Pentium IV CPUs running at 3.5GHz.

Cores, and IPC (Instructions per clock).
How many things can the CPU do per each clock cycle.

Consider a Honda Civic (i3-2120) and a school bus (12th Gen Alder Lake), going down the highway.
We need to get 100 people to the stadium, 50 miles away, in the least amount of time.

The Honda is carrying 4 people, going 60mph.
The schoolbus is going 55mph, and carrying 50 people.

Even though the Honda can go 'faster', it needs to make 25 round trips.
The bus...only 2 trips.

The bus people will be on their second beer, while the Honda people are still trundling down the road, or back in the parking lot.
