Introduction
1Introduction
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 Technology1. 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 Section 6.1, 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.
