Q5. How well does the Intel S478 Pentium 4 processor perform relative to the S423 Pentium® 4 processor?
A : At the same speed, S478 Pentium 4 CPU performs exactly the same as S423 Pentium 4 CPU because they are of the same processor core, same semiconductor technology, and same features. But Northwood will be faster than S423 Pentium 4 CPU due to its advanced 0.13-micron technology & larger 512KB L2 cache size.
From an overclocking perspective, with shorter trace route and hence better signal quality between CPU & chipset in Socket 478 package, S478 Pentium 4 platform has greater overclocking potential.
Q6. How large is the L2 cache of the Pentium 4 / Northwood processor?
A : The Intel S478 Pentium 4's L2 cache size is 256KB while Northwood's L2 cache size is 512KB.
