Different Core for P4

Out of curiosity, what exactly are the responsibilities of your job? How much are you supposed to know about hardware and how often do you work with hardware?

OK, the P4 from 1.3GHz to 2.0GHz was originally a Willimette. Late Willies were also available in Socket 478.

The Northwood is avaiable in 1.6, 1.8, and 2.0GHz at the same speeds as the Willimette. Higher speeds are all Northwood.

The Northwood CPU's are distinguished by venders in one or more ways: 512K Cache, Northwood, or an A after the speed (1.6A, 1.8A, 2.0A).

Your best bet for low cost Intels is some Asus P4S533 motherboards, Crucial PC2100 DDR SDRAM, and the fastest P4 Northwood CPUs you can afford with what's left.

yes. That change came like 2 years ago.

No, some 478's were willies. The following Socket 478 processor speeds were available in EITHER core:

1.6GHz
1.8GHz
2.0GHz

The following Socket 478 processors were Willimette Only:

1.5GHz
1.7GHz
1.9GHz

The following Socket 478 processors were Northwood only:

2.13GHz
2.2GHz
2.25GHz
2.4GHz
2.5GHz
2.53GHz
2.6GHz
2.67GHz
2.8GHz
3.06GHz

So basically the P4 Willimette only went as high as 2.0GHz. For the 3 speeds that had Either core, you have to look at other factors: The Northwood version of the 1.6GHz, 1.8GHz, and 2.0GHz will be labled as having 512k cache, .13 micron, Northwood, or have an A after the name (1.6A, 1.8A, 2.0A). All of these indicators mean Northwood.

Not really considering what Intel was trying to do. Intel told EVERYONE before Socket 423 was released that it was a temporary platform, it was going to be replaced. They hadn't finallized Socket 478 specifications yet. When they did, they released it, but there wasn't any Northwood processors for it! Now, they had two choices: Force their customers (mostly large OEM's like Dell) to convert the motherboard and CPU simultaniously, or release the board FIRST with a Socket 478 Willy.

Now, Intel garuntees an upgrade path to their OEMs. Which means that no Dell should have been factory equiped with a 2.0GHz S423 processor, as that was the "upgrade processor" for older boards. Instead, all Dell 2.0GHz machines had to be S478, so that they could take 2.4GHz processors, etc. Without the Woody in production, Intel provided Willies in Socket 478. So the Socket 478 Willy was a transition processor, and the Socket 423 Willy 2.0GHz was the "upgrade path" for older boards!
