cache hit rate on reads/store operations.
Error-correcting code for System Bus data
Data Prefetch Logic
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
®
MMX™ 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.
