Introduction The Intel® Pentium® 4 processor on 90 nm process in the 775-land package is a follow on to the Pentium 4 processor in the 478-pin package with enhancements to the Intel NetBurst® microarchitecture. The Pentium 4 processor on 90 nm process in the 775-land package uses FlipChip Land Grid Array (FC-LGA4) package technology, and plugs into a 775LGA socket. The Pentium 4 processor in the 775-land package, like its predecessor, the Pentium 4 processor in the 478-pin package, is based on the same Intel 32-bit microarchitecture and maintains the tradition of compatibility with IA-32 software. • Available at 3.80 GHz, 3.60 GHz, 3.40 GHz, 3.20 GHz, 3 GHz, and 2.80 GHz • Supports Hyper-Threading Technology1 (HT Technology) for all frequencies with 800 MHz front side bus (FSB) • Intel® Pentium® 4 processors 571, 561, 551, 541, 531, and 521 support Intel® Extended Memory 64 Technology (EM64T)Φ • Supports Execute Disable Bit capability • Binary compatible with applications running on previous members of the Intel microprocessor line • Intel NetBurst® microarchitecture • FSB frequency at 800 MHz • Hyper-Pipelined Technology • Advance Dynamic Execution • Very deep out-of-order execution • Enhanced branch prediction • Optimized for 32-bit applications running on advanced 32-bit operating systems • 16-KB Level 1 data cache • 1-MB Advanced Transfer Cache (on-die, fullspeed Level 2 (L2) cache) with 8-way associativity and Error Correcting Code (ECC) • 144 Streaming SIMD Extensions 2 (SSE2) instructions • 13 Streaming SIMD Extensions 3 (SSE3) instructions • Enhanced floating point and multimedia unit for enhanced video, audio, encryption, and 3D performance • Power Management capabilities • System Management mode • Multiple low-power states • 8-way cache associativity provides improved cache hit rate on load/store operations • 775-land Package
