Pentium IV - 1.9GHz - Willamette

The second incarnation of the Pentium 4 was offered in Socket 478 form, but it was the same core as it's disastrously slow predecessor. The 256Kb of Level 2 cache and the Netburst core weren't a good combo, but at 1.9GHz it was at least capable of most tasks thrown at it.

Of course, AMD's Athlon murdered it in most benchmarks. See the Northwood core 3.0GHz CPU elsewhere on this site to see the difference 512Kb of cache and ludicrously high clock speeds made.

This particular CPU is relegated to being part of my HTPC (Home Theatre PC), as it sits in a stupidly quiet DELL case. Married with 512MB of PC133 Ram, this system is only good enough
