17-inch MacBook Pro Developer Note

This note describes the 17-inch MacBook Pro computers introduced in October 2006 and based on the 2.33 GHz Intel Core 2 Duo microprocessor. It includes information about distinguishing features of the computer, including components on the main logic board: the microprocessor, the other main ICs, and the buses that connect them to each other and to the I/O interfaces.

The computer comes with Mac OS X version 10.4.8 installed.

The value of the 17-inch MacBook Pro model identifier string is MacBookPro2,1.

Architecture

The architecture of the 17-inch MacBook Pro is based on the Intel Core 2 Duo microprocessor and two ICs, the North Bridge memory controller and the South Bridge I/O controller, connected to each other by a Direct Media Interface (DMI) bus. The North Bridge IC provides the bridging functionality among the processor, the memory system, the DMI bus, and the 16-lane PCI Express bus to the graphics controller. The South Bridge IC supports these components:

A DMA controller internal to the South Bridge supports LPC DMA (low pin count direct memory access). The DMA controller has registers that are fixed in the lower 64 KB of I/O space. The DMA controller is configured using registers in the PCI configuration space.

Figure 1 provides a simplified block diagram of the North Bridge and South Bridge ICs and the buses that connect them together.

This block diagram shows the memory controller and I/O controller ICs and the buses that connect them on the main logic board. Each component in the block diagram is defined in text.

Features

The 17-inch MacBook Pro computer includes a built-in iSight video camera, an integrated IR receiver, and the Apple Remote. For a complete list of user-visible features, see the 17-inch MacBook Pro specification sheet at Apple's Specifications site. Other features are described in this section.

Intel Core 2 Duo Microprocessor

The microprocessor in the 17-inch MacBook Pro is an Intel Core 2 Duo with a clock speed of 2.33 GHz. It has the following features:

  • 2.33 GHz dual core processors

  • 4 MB shared L2 cache

  • Intel Advanced Digital Media Boost

  • Connection to the North Bridge IC over a 667 MHz frontside bus

  • Supports Intel 64 Architecture

See the Intel Core 2 Duo Processors support site for detailed microprocessor documentation.

Intel Advanced Digital Media Boost accelerates data manipulation by applying a single instruction to multiple data at the same time, known as SIMD processing. SIMD technology accelerates vector math operations and floating-point calculations. Advanced Digital Media Boost supports Intel Streaming SIMD Extensions (SSE) versions 1, 2, and 3 and allows the processor to execute an SSE3 instruction every clock cycle.

For information on Advanced Digital Media Boost, refer to Technology@Intel Magazine.

Intel 64 architecture increases the linear address space for software to 64 bits and supports physical address space up to 40 bits. The technology also introduces a new operating mode referred to as IA-32e mode. IA-32e mode operates in one of two sub-modes:

  • Compatibility mode enables a 64-bit operating system to run most legacy 32-bit software unmodified

  • 64-bit mode enables a 64-bit operating system to run applications written to access 64-bit address space

In the 64-bit mode, applications may access:

  • 64-bit flat linear addressing

  • 8 additional general-purpose registers (GPRs)

  • 8 additional registers for streaming SIMD extensions (SSE, SSE2, SSE3 and SSSE3)

  • 64-bit-wide GPRs and instruction pointers

  • Uniform byte-register addressing

  • Fast interrupt-prioritization mechanism

  • New instruction-pointer relative-addressing mode

An Intel 64 Architecture processor supports existing IA-32 software because it is able to run all non-64-bit legacy modes supported by IA-32 architecture. Most existing IA-32 applications also run in compatibility mode.

Processor Bus

The processor bus is an up-to-667 MHz bus connecting the processor to the North Bridge IC. The bus has 32-bit wide data running in both directions. The processor has 32-bit addressing.

The point-to-point architecture provides each subsystem with dedicated bandwidth to main memory. The North Bridge IC implements an independent processor interface. The input clock to the processor PLL is 166 MHz.

Memory

The computer provides two RAM slots that accommodate 200-pin DDR2 SDRAM SO-DIMMs up to 1.25” in height. The SO-DIMMs must be 667 MHz, PC2-5300, unbuffered, non-ECC compliant devices. The 17-inch MacBook Pro ships with two 1GB DDR2 SDRAM SO-DIMMs installed, for a total of 2GB. For additional information, refer to RAM Expansion Developer Note.

Direct Media Interface Bus

The North Bridge and South Bridge ICs are connected by a Direct Media Interface (DMI) bus, a high-speed, bidirectional, point-to-point link supporting a clock rate of 1 GB per second in each direction

Extensible Firmware Interface (EFI) Boot ROM

The Extensible Firmware Interface (EFI) Boot ROM consists of 2 MB of on-board flash EEPROM. It includes the hardware-specific code and tables needed to start up the computer, load an operating system, and provide common hardware access services.The EFI Boot ROM connects to the South Bridge via Serial Peripheral Interface (SPI) bus.

Graphics/Video Subsystem

The graphics subsystem includes an ATI Mobility Radeon X1600 IC, with 256 MB GDDR3 SDRAM, connected to the North Bridge IC by a x16 link (16 lane), dual simplex, 2.5 GHz PCI Express bus. The 17-inch MacBook Pro has a dual-link DVI connector for an external video monitor and supports video mirroring mode and extended desktop display mode. For more information on the graphics subsystem and display capabilities, refer to Video Developer Note.

For more information on PCI Express, refer to PCI Developer Note.

Serial ATA Drive Interface

The 17-inch MacBook Pro comes with a 160 GB 5400 rpm (optionally, a 200 GB 4200 rpm or 100 GB 7200 rpm) Serial ATA (SATA) Gen-I (1.5 Gbps) hard disk drive. The SATA hard disk drives operate through an AHCI 1.1 controller that supports advanced SATA-II features such as Native Command Queuing (NCQ) and PHY power management.

For more information on SATA, see the Serial ATA International Organization (SATA-IO) website.

For information on the AHCI controller, see http://www.intel.com/technology/serialata/ahci.htm.

Ultra ATA Interface

In the 17-inch MacBook Pro computer, the South Bridge controller provides an Ultra ATA/100 interface (running at UATA/66) to the slot-loading, SuperDrive. The drive can read and write DVD media and CD media, as shown in Table 1.
