Good, but ever since Intel transitioned to the ARK solely (from the Intel Processor Spec Finder, whose interface I found easier to use), they messed up a lot of data, and still haven't corrected it. A 130nm Pentium 4 Northwood 1.8 Ghz, for example, is listed as having a 68.1 W TDP, when that is plainly wrong (about right for a 180nm Pentium 4 Willamette, which is listed as having a 66.7 W TDP), the real TDP is 42 W. Also, the Pentium 4 Northwood with HT 3 Ghz 800 Mhz FSB pure and simply doesn't have a TDP listed, when it did back when the general public could search with the Intel Processor Spec Finder (if I remember correctly it's 81.9 W).
This has been wrong for years now. They probably have the new CPUs information right, but it would be useful to not mess up history. If they don't take care of it, who knows if in a few years, in another transition, they don't mess up the current CPUs specs too. After all, what good is a database if the information you have in it is wrong or missing ?
