Processor Performance

SimonTemplar · 2013-12-28 15:51:56

If an old Pentium 4 and an new i5 both have a clockspeed of 2.8, I presume the i5 still performs better. Why? What other factors are taken into account when determining a processor's overall performance? Thanks

The number of cores is the main difference mate. The i5 will have 4 or so but the pentium will only have the single core.

Compared to an i5;
Smaller number of CPU cores,
Handles fewer threads,
Base frequency is lower,
Lacks some instructions,
No integrated GPU,
The socket is obsolete
