architecture. These features include:
•
SIMD instruction extensions including MMX
Streaming SIMD Extensions (SSE), Streaming SIMD Extensions 2
(SSE2), and Streaming SIMD Extensions 3 (SSE3)
•
Microarchitectures that enable executing instructions with high
throughput at high clock rates, a high speed cache hierarchy and the
ability to fetch data with high speed system bus

Multi-core architecture supported in Intel
Pentium
Intel Pentium 4 processors, Intel Xeon processors, Pentium D
processors, and Pentium processor Extreme Editions are based on Intel
NetBurst
microarchitecture balances performance and low power consumption.
1. Hyper-Threading Technology requires a computer system with an Intel processor
supporting HT Technology and an HT Technology enabled chipset, BIOS and operating
system. Performance varies depending on the hardware and software used.
2. Dual-core platform requires an Intel Core Duo, Pentium D processor or Pentium processor
Extreme Edition, with appropriate chipset, BIOS, and operating system. Performance
varies depending on the hardware and software used.
