Intel Celeron Willamette CPU family was the first Celeron family
based on NetBurst micro-architecture. The Celeron microprocessors
used modified version of Pentium 4 Willamette core. The size of level
2 cache in this core was slashed in half - from 256 KB to 128 KB, in
all other aspects the core didn't change. Like Pentium 4 Willamette
CPUs, the Celeron microprocessors had 20-stage pipeline, 16 KB data
cache, instruction trace cache for approximately 12000
micro-operations, quad-pumped 100 MHz Front Side Bus (effectively 400
MHz FSB), included SSE2 instructions and were manufactured on 0.18
micron technology. Celerons and Pentium 4 Willamette processors had
the same core voltage and similar power requirements. The Celerons
were packaged in 478-pin Flip-Chip PGA package and worked in socket
478 motherboards.
Performance of Willamette Celeron microprocessors was close to the
one of Pentium 4 processors with the same core. On average, the
Celerons were 10% slower than Pentium 4 CPUs. It's important to note,
though, that by the time Intel released Willamette Celeron processors
the Pentium 4 Willamette core was already obsolete and it had been
replaced by Pentium 4 Northwood core.
