What’s a 386 processor? What does 45nm mean? What is a 775 slot type?
Question:
No one can seem to tell me the difference between the two (45nm and x38)? What do these numbers mean, and are they both just CPU’s of different generations? I can’t seem to see these numbers in any specifications for processors, so how do you know which processors are which? I hope you can help, since no one I know can tell me. It’s important because I want to buy a new motherboard and want to make sure everything is compatible. Also, if you can tell me, what does the 775 number mean? I sent a copy of this to my brother, who knows a lot more about computers than I do.
Answer:
A few quick answers for you:
The 775 number refers to a “775 socket”. A computer’s CPU will plug into a certain type of slot on the motherboard. The 775 socket is a certain type of slot. If you have a motherboard with a 775 socket type, and you’re purchasing a CPU for it, you want to make sure the CPU is also a 775 socket type.
The “x38” number you mention is probably a partial description. It’s most likely a variation of “x386” or “x86”. A 386 processor or “x86” processor is a certain type of CPU used in old computers. Compared to today’s machines, this processor was very slow.
Finally, “45nm”: This is a certain type of advanced processor. Read for more detail on the 45nm semiconductor.
All these numbers are pretty technical, and are generally not considered when purchasing a new PC. (That’s for the general population – if you’re a techie, these numbers might be pretty important!) Also see this link for minimum hardware recommendations when purchasing a new computer.
