NotepadHyperthreading - allows clock speed so CPU is not just sitting there. Hyperthreading

Hyperthreading does not waste you CPU


NotepadClock Speed

MHz-1 Million cycles per second
GHZ 1 billion cycles per second
Cash Memory is local memory on CPU+L1 +
Cash helps CPU get memory
L1

Speed – number of mill

Cache – Local Memory on CPU Helps get
L1 Cache is the first place we check but is relatively small few kb.
L2 2nd place checks Maybe
L3 is last check

Bus speed tells how fast
Front side bus (Intel)
AMD does not have front side bus but uses own memory transport

Clock speed indicate MHZ 1 Million per sec.
Gighz 1 billion cycles per second.

Cache memory – Helps the CPU get memory

local memory L1 is the first place we check and is relatively small
Second place the CPU checks L-2 memory

Bus speed – Front side bus (Intel)
AMD
