Fastest Pentium II on the way By Jim Davis January 14, 1998, 4:00 a.m. PT Intel (INTC) is expected to release the fastest of its fastest chips later this month, but don't expect major performance gains. Those will come later when Intel modifies a core part of the intercomponent "plumbing" for the Pentium II. The newest Pentium II, expected to be officially announced at the end of this month, will reach a top speed of 333 MHz, up from 300 MHz, as an Intel executive indicated yesterday: "We [have begun] volume shipments of the 333 MHz version of this product in anticipation of its introduction later this month," Paul Otellini, executive vice president director at the Sales and Marketing Group, said yesterday. Yet the newest and speediest Intel processor line is chained, in some respects, to an older PC architecture which can keep the chip from realizing its full potential for some applications, particularly sophisticated ones. This will change, and the biggest performance gains for the Pentium II will come, when Intel fattens the data pipe, or "bus," to which the processor is hooked. This allows for an increase in the flow of data which, in turn, makes conditions optimal for chips running at speeds of 400 MHz and higher. "Certainly, a faster bus is going to be most helpful in the workstation and server environment. In those areas particularly the [older] bus is running out of gas. In standard desktop PCs, it's still a reasonable design point," said Linley Gwennap, editor in chief of the Microprocessor Report. Currently, the Pentium II connects to a bus which runs at a tepid 66 MHz, the same speed that its older cousin, the Pentium, uses. The bus is used as a data conduit for "talking" to the rest of the computer system. Though the Pentium II has design improvements which mitigate the impact of the slow bus, it's ultimately a performance inhibiter, according to analysts. As previously reported, Intel is expected to increase the bus speed on upcoming systems to 100 MHz by mid-1998. This is important for improving a computer's overall system speed because performance bottlenecks can occur when future 450-MHz Pentium II processors slow down to talk to the bus.
