full speed Level 2 (L2) cache with Error

Correcting Code (ECC))

Dual Independent Bus (DIB) architecture:

Separate dedicated external System Bus and

dedicated internal high-speed cache bus

Internet Streaming SIMD Extensions for

enhanced video, sound and 3D performance

Binary compatible with applications running

on previous members of the Intel

microprocessor line

Dynamic execution micro architecture

Power Management capabilities

— System Management mode

— Multiple low-power states

Optimized for 32-bit applications running on

advanced 32-bit operating systems

Flip Chip Pin Grid Array (FC-PGA2) packaging

technology; FC-PGA2 processors deliver high

performance with improved handling protection

and socketability

Integrated high performance 16KB instruction

and 16KB data, nonblocking, level one cache

512KB Integrated Full Speed level two cache

allows for low latency on read/store operations

Quad Quadword Wide (256 bit) cache data bus

provides extremely high throughput on read/

store operations.

8-way cache associativity provides improved

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.
