CPU

The CPEx GX-333-X comes with a soldered low power AMD Geode GX-466 processor. The AMD

Geode design integrates high-performance graphics controller, VGA and Flat Panel display

interfaces, with the burst and concurrent GeodeLink pipelining capability for fast data distribution

among CPU, DRAM, and PCI buses. CPU and the major functionalities are provided in a single

processor package. The CPU is accompanied by the Geode CS5536AD Southbridge featuring

full-featured interfaces with integrated UltraDMA-33/66/100 IDE, USB, and a complete power

management feature set. The CS5536AD also provides hardware monitoring and super I/O

functions (floppy disk drive and serial/parallel ports).

The CPU is passively cooled over a heatsink made in aluminum alloy and is ideal for small form

factor computing applications with its low power consumption and minimum heat dissipation.

Shown below are some of the key features of the AMD Geode GX processor:

32-bit low-power x86 processor with MMX and 3DNow! technology extensions.

Processor frequency up to 300MHz.

32KB L1 cache, 16KB instruction and 16KB data.

Integrated thermal diode.

64-bit DDR memory controller.

Integrated FPU.

PCI 66MHz bus:

Industry standard PCI 2.2 specification compliant

Write gathering and write posting of inbound write requests

Supports fast back-to-back transactions

Optimized Unified Memory Architecture (UMA) with patented compression technology.

High-resolution CRT and TFT outputs (simultaneous operation)
