Pentium
III Processor, like the Pentium
Execution micro-architecture -- a unique combination of multiple branch
prediction, data flow analysis, and speculative execution. This enables the
®
Pentium
II Processor to deliver higher performance than the Pentium
processor, while maintaining binary compatibility with all previous Intel architec-
ture processors.
A significant feature of the Pentium
perspective, is the built-in direct multiprocessing support. In order to achieve
multiprocessing, and maintain the memory and I/O bandwidth to support it, new
system designs are needed. For systems with dual processors, it is important to
consider the additional power burdens and signal integrity issues of supporting
multiple loads on a high speed bus. The Pentium
card supports both uni-processor and dual processor implementations.

(Figure 1) cartridge packaging technology. The S.E.C. cartridge allows the L2
cache to remain tightly coupled to the processor, while maintaining flexibility
when implementing high performance processors into OEM systems. The second
level cache is performance optimized and tested at the cartridge level. The S.E.C.
cartridge utilizes surface mounted core components and a printed circuit board
with an edge finger connection. The S.E.C. cartridge package introduced on the
®
Pentium
II Processor will also be used in future Slot 1 processors.
The S.E.C. cartridge has the following features: a thermal plate, a cover and a PCB
with an edge finger connection. The thermal plate allows standardized heatsink
attachment or customized thermal solutions. The thermal plate enables a reusable
heatsink to minimize fit issues for serviceability, upgradeability and replacement.
The full enclosure also protects the surface mount components. The edge finger
connection maintains socketabilty for system configuration. The edge finger
connector is denoted as 'Slot 1 connector' in this and other documentation.
