Components for Building Computers From Scratch/cpu


I know the P3 CPU is an old CPU but I was just doing some reading on the net about the P3 CPU Socket 370.

And in the specs it says L2 256kB.

Now I know on CPUs now the L1 L2 and L3 are all on the CPU but with the P3 was the L2 on the CPU because I know the Older CPUs had the L2 on the Motherboard?

Thanks for the help.

The answer depends on *which* specific packaging you're talking about. There was a "middle era" of CPUs between chips that relied on L2 being external, to L2 being "on package" (but not "on die") meaning that the cache was a separate die on the same package (Slot 1 (Pentium II and early Pentium III) and Socket 8 CPUs (Pentium Pro) are examples). The Socket 370 chips, and the Slot 1 chips based on the same cores (Coppermine), do integrate the L2 into the die however.

I have nearly two decades of experience in IT, computer repair, and related fields and will attempt to provide the most solid, brand-agnostic advice when it comes time to purchase a new computer, or upgrade an existing machine. I can answer anything from the seemingly basic to the downright complicated - and will do my best to provide this information in a clear and concise manner.


I have been an enthusiast of PC's for many years, and can answer questions about the purchase/use of a new computer or the purchase, installation, and use of upgrades for existing computers. There probably isn't a whole lot related to the home computer that I haven't seen over the years.
