Intel's new processor naming system

[elm669]

I was reading the bestbuys mag and there is a emachines that says "Intel Pentium 4 processor 520" and at the bottom of the page it says operates at 2.8ghz

What's the deal on the new naming system?

Those are prescotts. Intel changed the naming scheme a while ago, when they found that heat would prevent ramping (at least these chips) much higher in clockspeed. It also differentiates them from the older Northwood cores.

so how does the naming system go?

The Intel naming system applies to all its consumer line of chips.

Intel 3xx - Celeron class chips
Intel 5xx - Pentium 4s (non-EE)
Intel 7xx - Pentium M, Pnetium 4 EE

The numbers are meant to represent the sum total of features and technologies on the processor, basically meaning the cache size, front side bus, clock speed, processor architecture, and whatever else is down the line.

By the way, have any of you looked at the desktop Dothan Pentium Ms? Expensive as hell.

Cool, I get it now.

Pentium M's are essentially like Athlons -- if you translate Athlon clock speed/PR rating, then you can guesstimate its performance pretty well.

2.0 is like ~ 2.6-2.8Ghz Desktop P4.

This is why the 1.5 and 1.8's can compete with the 2.2Ghz - 2.5ghz range of regular P4's. Of course, this is just a rough ballpark. But you get the picture.
