Slot 1 AGP Chipsets
Intel's Slot 1 CPUs are currently the fastest CPUs available for PCs and Slot 1 is a CPU interface patented by Intel. This is why there is no other CPU manufacturer producing Slot 1 CPUs currently. Slot 1 offers Intel's GTL+ bus protocol, known from the Pentium Pro CPU, which hosts the so called dual independend bus (DIB), which means that the Slot 1 CPUs have one bus which they use to communicate with the memory and system devices like the PCI and AGP bus and another bus for communication with the second level cache, which is built into the Pentium II CPU cartridges. GTL+ is particularly helpful for multi CPU systems and is a protocol that is patented by Intel as well. This means to other chipset manufacturers that they have to license the GTL+ protocol from Intel if they want to design their own Slot 1 chipsets.
Current Slot 1 CPUs are the Pentium II in the two flavors of 66 and 100 MHz front side bus (FSB) and the Celeron, which is nothing else than a Pentium II core without the second level cache and only designed for 66 MHz FSB.

Intel 440BX AGP Chipset - 66/100 MHz Front Side Bus - NOW ONLY THESE ARE IN RUN
Intel's BX chipset is the first PC chipset that is offering a system or front side bus that runs at 100 MHz and therefore enables a higher memory bandwidth as the common 66 MHz FSB used to.
Intel® 440BX AGPset
The Intel® 440BX AGPset is the first chip set to deliver 100-MHz system level bandwidth to unleash the full performance of the Intel® Pentium® II processors at 350-MHz or 400-MHz. In addition, the Mobile Intel® 440BX chip set is the first chip set to bring Pentium II processor performance to mobile systems.
The Intel 440BX AGPset improves system performance by increasing the bandwidth of the system bus from 66MHz to 100MHz.
Highest System Performance through Technology Innovation
The chip set features Intel's Quad Port Acceleration (QPA) to improve bandwidth between the Pentium II processor, the Accelerated Graphics Port, 100-MHz SDRAM and the PCI bus. QPA combines enhanced bus arbitration, deeper buffers, open-page memory architecture and ECC memory control to improve system performance.
Ultimate Design Flexibility
The Intel 440BX AGPset provides developers with maximum design flexibility by delivering one chip set for both 66MHz and 100MHz system designs. Now, one basic motherboard design supports all Pentium II processor speeds from 233MHz to 400MHz. This flexibility can save engineering resources while maximizing use of investments in BIOS, software development and compatibility testing.
Closing the Gap Between the Desktop and Mobile
The Intel 440BX chip set architecture supports Mobile Intel Pentium II processor performance—bringing desktop-like performance to mobile PCs.
