Updating prescott 80547 motherboard
Indeed, most industry analysts regarded the first Mendocino-based Celerons as too successful—performance was sufficiently high to not only compete strongly with rival parts, but also to attract buyers away from Intel's high-profit flagship, the Pentium II.
Overclockers soon discovered that, given a high-end motherboard, the Celeron 300A could run reliably at 450 MHz.
This was achieved by simply increasing the Front-side bus (FSB) clock rate from the stock 66 MHz to the 100 MHz clock of the Pentium II.
At this frequency, the Mendocino Celeron rivaled the fastest x86 processors available.
The 'Cel' of Celeron rhymes with 'tel' of Intel." Covington also shared the 80523 product code of Deschutes.
Although clocked at 266 or 300 MHz (frequencies 33 or 66 MHz higher than the desktop version of the Pentium w/MMX), the cacheless Celerons were a good deal slower than the parts they were designed to replace.
Instead, Intel pursued a budget part that was pin-compatible with their high-end Pentium II product, using the Pentium II's Slot 1 interface.
Whereas Covington had no secondary cache at all, Mendocino included 128 KB of L2 cache running at full clock rate.Subsequent Celeron branded CPUs were based on the Pentium III, Pentium 4, Pentium M, and Intel Core branded processors.The latest Celeron design (as of January 2016 As a product concept, the Celeron was introduced in response to Intel's loss of the low-end market, in particular to the Cyrix 6x86, the AMD K6, and the IDT Winchip.Although the other Mendocino Celerons (the 333 MHz part, for example) did not have an A appended, some people call all Mendocino processors Celeron-A regardless of clock rate.The new Mendocino-core Celeron was a good performer from the outset.
