Intel
Pentium
III Processor with 512KB L2
Cache at 1.13GHz to 1.40GHz
Datasheet
Product Features
The Pentium
III
processor with 512KB L2 Cache is designed for high-performance workstations and
servers. It is binary compatible with previous Intel architecture processors. The Pentium
III
processor
with 512KB L2 Cache provides great performance for applications running on advanced operating
systems such as Windows* 98, Windows* NT, Windows* 2000, Windows* Me and Linux. This is
achieved by integrating the best attributes of Intel processors--the dynamic execution, Dual
Independent Bus architecture plus Intel
MMXTM technology and Internet Streaming SIMD
Extensions--bringing a new level of performance for systems buyers. The Pentium
III
processor with
512KB L2 Cache extends the power of the Pentium
II processor with performance headroom for
business media, communication and internet capabilities. Systems based on the Pentium
III
processor
with 512KB L2 Cache also include the latest features to simplify system management and lower the
cost of ownership for large and small business environments. The Pentium
III
processor with 512KB
L2 Cache offers great performance for today's and tomorrow's applications.
