Socket 478 Pentium 4 Processor FAQ
Q1. What are the key features of Socket 478 Pentium 4 and Northwood CPUs? And what's the difference between S478 and S423 CPUs?
A : Basically Socket 478 Pentium 4 CPU is utilizing the same .18-micron technology and has the same processor core (Willamette) as current Socket 423 Pentium 4 CPU. So it has exactly the same features as its predecessor S423 Pentium 4 CPU. Socket 478 Pentium 4 CPU utilizes FC-PGA2 package technology, so it has a IHS (Integrated Heat Spreader) on the top of the chip. It is also designed to be installed onto a smaller-sized surface-mount, 478-pin, ZIP socket, referred as a mPGA478 socket. The new Socket 478 interface is designed as a transition vehicle to migrate to .13-micron process Northwood CPU. Pentium 4 CPU support 400MHz NetBurst microprocessor architecture, and add 144 SSE2 new instructions. S478 Pentium 4 CPU with Willamette core utilizes .18-micron process technology and has 256KB L2 cache, while Pentium 4 CPU with Northwood core utilizes .13-micron process technology and has 512KB L2 cache.
Q2. At what clock speeds will the Intel S478 Pentium 4 and Northwood processors operate?
A : Initial versions of the Intel Pentium 4 processor are planned to operate at clock speeds of 2.0G and 1.9GHz, based on Intel's 0.18-micron process technology. Later on, there will be 1.8GHz, 1.7GHz or lower speed versions for value PC segment. Northwood's speeds will range from 2.0GHz to 2.4GHz and beyond.
Q3. When will the Intel S478 Pentium 4 processor be available in the marketplace? Will S423 Pentium 4 processor be phased out?
A : The new Intel Pentium 4 processor is shipped to computer manufacturers from early August. ASUS motherboards will be mass-delivered in a short time. Current Intel S423 Pentium 4 will not be phased out soon, but its highest frequency will not exceed 2.0GHz, while S478 Pentium 4 CPU's frequency could extend to 2.4GHz or above with new .13-micron process technology and the Northwood core. So, for any newly-planned platform development considerations, S478 Pentium 4 platform will be the best choice.
Q4. How well does the Intel S478 Pentium 4 processor perform relative to the S423 Pentium® 4 processor?
A : Yes. Intel S478 Pentium 4 based system has better performance than all existing PC systems, and it fully utilizes the most advanced process technology to stretch its computing power into 2.4GHz and beyond. Most importantly, the price for such an advanced, next-generation CPU could priced affordably for everyone. S423 Pentium 4 platform might be your interest, but due to lack of higher CPU speed support (limited to 2.0GHz), if future upgradeability and longer system life cycle is your concern, then S478 Pentium 4 platform will be your only choice.
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.
