Intel
Pentium
III Processor with 512KB L2 Cache at 1.13GHz to 1.40GHz
1.0
Introduction
The Intel Pentium
III
processor with 512KB L2 Cache for the PGA370 socket is the next
member of the P6 family, in the Intel IA-32 processor line and hereafter may be referred to as
simply “the processor”. The Intel Pentium
III
processor with 512KB L2 Cache will continue in
the package technology called flip-chip pin grid array but will contain a Integrated Heat Spreader
(IHS) (see
Figure 1
). The flip-chip with IHS package will be labeled as FC-PGA2 and will utilize
the same 370-pin zero insertion force socket (PGA370). Thermal solutions contact the IHS directly
for the FC-PGA2 package and not to the bare-die as with the FC-PGA attachment.
The Intel Pentium
III
processor with 512KB L2 Cache, like its predecessors in the P6 family of
processors, implements a Dynamic Execution microarchitecture—a unique combination of
multiple branch prediction, data flow analysis, and speculative execution. This enables these
processors to deliver higher performance than the IntelPentium processor, while maintaining
binary compatibility with all previous Intel architecture processors. The processor also executes
Intel
MMX
TM
technology instructions for enhanced media and communication performance just
as its predecessor, the Intel Pentium
III
processor (CPUID = 068xh). Additionally, the Intel
Pentium
III
processor with 512KB L2 Cache executes Streaming SIMD (single-instruction,
multiple data) Extensions for enhanced floating point and 3-D application performance. Data
Prefetch Logic adds functionality that anticipates the data needed by the application and pre-loads
it into the Advanced Transfer Cache, further increasing processor and application performance.
The processor utilizes multiple low-power states such as Sleep, and Deep Sleep to conserve power
during idle times.
The processor includes an integrated on-die 512KB 8-way set associative level-two (L2) cache.
The L2 cache implements the Advanced Transfer Cache architecture with a 256-bit wide bus. The
processor also includes a 16 KB level one (L1) instruction cache and 16 KB L1 data cache. These
cache arrays run at the full speed of the processor core. The Intel Pentium
III
processor with
512KB L2 Cache for the PGA370 socket has a dedicated L2 cache bus, thus maintaining the dual
independent bus architecture to deliver high bus bandwidth and performance. Memory is cacheable
for 64 GB of addressable memory space, allowing significant headroom for desktop systems. Refer
to the Specification Update document for this processor to determine the cacheability and cache
configuration options for a specific processor. Please contact your nearest Intel Sales
Representative for the latest Processor Specification Update.
The Intel Pentium
III
processor with 512KB L2 Cache will support a lower voltage differential
and single-ended clocking for the system bus. The Intel Pentium
III
processor with 512KB L2
Cache will not function in a previous generation platform due to incompatible system bus signal
levels and clock type. Care must be taken to ensure the correct processors are installed in the
correct PGA370 socket platforms.
