Intel 430NX ("Neptune")

The 430NX was the original chipset used for Intel's second generation Pentium chips, covering Pentiums with speeds from 90 to 133 MHz (which, of course, also work in later Pentium chipsets). The biggest improvement with this generation of technology was the newer Pentium itself: it ran much faster, cooler and more reliably than the first generation Pentiums did. Dual processor support.

• Support for 512 MB of system memory
• Support for up to 512 KB of asynchronous L2 cache.

 Intel 430FX ("Triton")

The FX's primary contribution technology-wise was support for EDO RAM. The FX chipset started the ball rolling toward the eventual shift in dominance from Fast Page Mode (FPM) to Extended Data Out (EDO) memory.

• Support for EDO memory.
• Supported for pipelined burst cache and synchronous cache technologies.
• PCI level 2.0 compliance.
• Improved performance, in general.
• Maximum 128 MB RAM.
• No support for dual processing.

 Intel 430HX ("Triton II")

• Support for parity and ECC memory.
• Dual processor support.
• Support for 512 MB of system memory instead of just 128 MB.
• Support for 512 MB of cached system memory instead of just 64 MB
• Much improved performance, due to faster memory timing and more I/O buffers.
• PCI level 2.1 compliance.
• USB support.
• Independent device timing for IDE/ATA drives.

• Support for AGP
• UDMA 66.
• 66MHz bus

 Intel 440 BX

• 100 MHz bus.
• Supports PII and PIII

 Typical Hub Chipsets

• 100 MHz bus.
• Integrated AGP graphics but no AGP upgrade slot

 Intel 815
