This section examines the basics
of selecting and installing a CPU. Concepts covered include:
- Considerations for choosing a
- 32-bit or 64-bit processor
- Process size
- Mobile processors
- Integrated memory controller
- Details about CPU performance
- Processor socket categories:
- Pin Grid Array (PGA)
- Land Grid Array (LGA)
- Commonly-implemented processor sockets
- Details when installing a CPU
Lecture Focus Questions:
- What is the difference between the
three levels of cache memory?
- What is the biggest limitation of
using a 32-bit processor?
- What factors should be considered when
comparing the speed of computers?
- What are the benefits of using a
smaller process size during CPU manufacture?
- What is the difference between
hyper-threading and multithreading?
- Hyper-threading is using one processor but logically dividing it into two so that it gives the user the benefit of two processors with only using the resources equivalent to almost one. This is achieved by sharing, partitioning and duplicating the various resources almost into two processors. Used by the latest Pentium processors, which are HT enabled, in layman's terms, it allows you to use more than two applications at the same time without slowing down processing speed.
Multi-threading is when various processes are time sliced such that it gives the user the impression that all the programs are being run at the same time. This is what happens on your computer regularly.
Super-threading allows threads from different processes to be executed at the same time unlike Multi-threading where every process has a time slot during which, thread from only one process will be executed. But every time, if for example, there are four instructions issued to the processor. They will all be from the same process. Hyper-threading takes it a step further. It allows threads from different processes to be issued at the same time, in turn, utilizing the waste cycles of the processor. You can go to any Intel site for further info on this.
