The Acer TravelMate 6463WLMi notebook features the Intel Core 2 Duo T5500 processor with a clock rate of 1.66GHz. This CPU is based on the 65nm Merom core and has 2 megabytes of shared L2 cache memory.
The Core 2 Duo T5500 supports Intel’s 64-bit extensions to the x86 architecture and also features Intel Wide Dynamic Execution technology which means more decoders and execution units in the CPU core. The speed of processing SSE and floating-point instructions has been increased, too.
Besides Intel’s traditional Enhanced SpeedStep technology that gives the notebook’s software and BIOS the control over the CPU frequency multiplier (to reduce it under low loads), this CPU supports Dynamic Power Coordination (the power consumption of the cores can be independently adjusted depending on the current load; one core may even slip into Deep Sleep mode with the lowest power consumption possible) and Dynamic Cache Sizing (unused segments of the CPU cache can be turned off to save power).

This implementation of the refresh version of the Napa platform also incorporates an Intel PRO/Wireless 3945ABG adapter and an Intel Calistoga 945PM chipset. This chipset supports DDR2 SO-DIMMs, thus offering more memory bandwidth at lower power consumption, and a PCI Express x16 interface for an external graphics card. Connected to the North Bridge via a special-purpose Direct Media Interface, the South Bridge (ICH7-M) supports one Parallel ATA port, two Serial ATA ports, eight USB 2.0 ports and Intel High Definition Audio. It also offers six PCI Express x1 lanes to connect external devices. For more information about the platform, visit the manufacturer’s website.
This configuration is complemented with a discrete graphics core ATI Mobility Radeon X1300 with 128MB of dedicated graphics memory.
The ATI Mobility Radeon X1300 is a 105-million-transistor chip manufactured on 90nm tech process, which improves its power consumption characteristics.
Providing multi-threaded rendering technology and a ring-bus memory controller for high performance, the ATI Mobility Radeon X1300 also incorporates the Avivo video engine for high-quality video playback and features PowerPlay 6.0 technology for a longer battery life. But what is true for all mobile solutions from ATI, the graphics subsystem’s power-saving mode is set up rather too aggressively. When the notebook works on its battery, its graphics performance becomes closer to an integrated graphics core rather than to a full-featured discrete GPU.
