Introduction
The Intel
®
 Pentium
®
 4 processor on 90 nm process is a follow on to the Intel
®
 Pentium
®
 4 
processor in the 478-pin package with enhancements to the Intel NetBurst
®
 microarchitecture. The 
Pentium 4 processor on 90 nm process uses Flip-Chip Pin Grid Array (FC-mPGA4) package 
technology, and plugs into a 478-pin surface mount, Zero Insertion Force (ZIF) socket, referred to 
as the mPGA478B socket. The Pentium 4 processor on 90 nm process, like its predecessor, the 
Pentium 4 processor in the 478-pin package, is based on the same Intel 32-bit microarchitecture 
and maintains the tradition of compatibility with IA-32 software. 
Note:
In this document the Pentium 4 processor on 90 nm process is also referred to as the processor.
The Pentium 4 processor on 90 nm process supports Hyper-Threading Technology
1
. Hyper-
Threading Technology allows a single, physical processor to function as two logical processors. 
While some execution resources (such as caches, execution units, and buses) are shared, each 
logical processor has its own architecture state with its own set of general-purpose registers, 
control registers to provide increased system responsiveness in multitasking environments, and 
headroom for next generation multithreaded applications. Intel recommends enabling Hyper-
Threading Technology with Microsoft Windows* XP Professional or Windows* XP Home, and 
disabling Hyper-Threading Technology via the BIOS for all previous versions of Windows 
operating systems. For more information on Hyper-Threading Technology, see www.intel.com/
info/hyperthreading. Refer to 
, for Hyper-Threading Technology configuration details.
In addition to supporting all the existing Streaming SIMD Extensions 2 (SSE2), there are 13 new 
instructions that further extend the capabilities of Intel processor technology. These new 
instructions are called Streaming SIMD Extensions 3 (SSE3).These new instructions enhance the 
performance of optimized applications for the digital home such as video, image processing and 
media compression technology. 3D graphics and other entertainment applications (such as gaming) 
will have the opportunity to take advantage of these new instructions as platforms with the Pentium 
4 processor on 90 nm process and SSE3 become available in the market place.
The processor’s Intel NetBurst microarchitecture front side bus (FSB) uses a split-transaction, 
deferred reply protocol like the Pentium 4 processor. The Intel NetBurst microarchitecture FSB 
uses Source-Synchronous Transfer (SST) of address and data to improve performance by 
transferring data four times per bus clock (4X data transfer rate, as in AGP 4X). Along with the 4X 
data bus, the address bus can deliver addresses two times per bus clock and is referred to as a 
"double-clocked" or 2X address bus. Working together, the 4X data bus and 2X address bus 
provide a data bus bandwidth of up to 6.4 GB/s.
Intel will enable support components for the processor including heatsink, heatsink retention 
mechanism, and socket. Manufacturability is a high priority; hence, mechanical assembly may be 
completed from the top of the baseboard and should not require any special tooling.
The processor includes an address bus powerdown capability that removes power from the address 
and data pins when the FSB is not in use. This feature is always enabled on the processor.
