PCI Local Bus 32-Bit High Speed Expansion Slots
The three PCI local bus, high speed expansion slots move information at
up to 132 MB/s. This offers a high performance, 32-bit interface to
support local bus peripherals such as video cards, LAN adapters and hard
disk drives.
Secondary Cache Subsystem
The secondary (Level 2) cache subsystem enhances the performance of
the CPU. The onboard cache controller allows cache memory to provide
an ultra high-speed, 12-15-nanosecond buffer between the CPU and
conventional (50, 60, or 70ns) RAM. Your system can accommodate three
cache configurations: 0K, 256K, or 512K of Level 2 cache. The single
cache slot (labelled CACHE) is located next to the CPU.
Continuous Full-Speed Processing
Pantera systems now run continuously at maximum speed, eliminating
Turbo Mode. Because of this, the Turbo button and Turbo LED are not
used on Pantera systems.
