Introduction; Core™2 Quad Processor Q9000 Series) - Intel Q9300 - Core 2 Quad 2.5 GHz 6M L2 Cache 1333MHz FSB LGA775 Quad-Core Processor Datasheet

Introduction

1 Introduction
The Intel
processor Q9000, Q9000S, Q8000, and Q8000S series are based on the Enhanced
®
Intel Core™ microarchitecture. The Enhanced Intel Core microarchitecture combines
the performance of previous generation Desktop products with the power efficiencies of
a low-power microarchitecture to enable smaller, quieter systems. The Intel
Extreme processor QX9000 series and Intel
Q8000, and Q8000S series are 64-bit processors that maintains compatibility with IA-
32 software.
The processors use a Flip-Chip Land Grid Array (FC-LGA6) package technology, and
plugs into a 775-land surface mount, Land Grid Array (LGA) socket, referred to as the
LGA775 socket.
Note: In this document, the Intel
Core™2 Quad processor Q9000, Q9000S, Q8000, and Q8000S series may be referred
to simply as "the processor."
Note: The following products are covered in this document:
• The Intel
QX9650.
• The Intel
Q9505, Q9450, Q9400, and Q9300.
• The Intel
and Q9400S.
• The Intel
Q8400.
• The Intel
Q8400S.
The processor is based on 45 nm process technology. The processor features the Intel
Advanced Smart Cache, a shared multi-core optimized cache that significantly reduces
latency to frequently used data. The processors feature 1600 MHz and 1333 MHz front
side bus (FSB) frequencies.The processors also feature two independent but shared
12 MB of L2 cache (2x6M), two independent but shared 8 MB of L2 cache (2x4M), two
independent but shared 6 MB of L2 cache (2x3M) or two independent but shared 4 MB
of L2 caches (2x2M).
The processor supports all the existing Streaming SIMD Extensions 2 (SSE2),
Streaming SIMD Extensions 3 (SSE3), Supplemental Streaming SIMD Extension 3
(SSSE3), and the Streaming SIMD Extensions 4.1 (SSE4.1). The processor supports
several Advanced Technologies: Execute Disable Bit, Intel
and Enhanced Intel SpeedStep

Q9000S series support Intel
The processor's front side bus (FSB) uses a split-transaction, deferred reply protocol.
The FSB uses Source-Synchronous Transfer of address and data to improve
performance by transferring data four times per bus clock (4X data transfer rate).
Along with the 4X data bus, the address bus can deliver addresses two times per bus
clock and is referred to as a "double-clocked" or 2X address bus. Working together, the
4X data bus and 2X address bus provide a data bus bandwidth of up to 12.4 GB/s.
