As it had in the past, Intel faced competitors who sold CPUs with similar performance at lower prices. Most high-priced desktop computers and servers were sold with a Pentium of one sort or another, but home and entry-level PCs were another matter. Enter a variation of the SX concept—the Celeron.
Celeron models available in 500, 466, 433, 400, 366, and 333 MHz have expanded Intel processing into the market for computers selling for less than $1,200.
All the Intel Celeron processors are available in PGA packages. The versions operating at 433, 400, 366, 333, and 300 MHz are also available in single-edge processor packages (see Figure 4.12).
Key features include the following
• MMX media enhancement technology.
• Dynamic Execution Technology.
• A 32-KB (16-KB/16-KB) nonblocking, L1 cache for fast access to heavily used data.
• Celerons operating at 500, 466, 433, 400, 366, and 333 MHz include integrated 128-KB L2 cache.
• All Celeron processors use the Intel P6 microarchitecture's multitransaction system bus at 66 MHz. Processors at 766, 733, 700, 667, 633, 600, 566, 533, 500, 466, 433, 400, 366, and 333 MHz use the Intel P6 microarchitecture's multitransaction system bus with the addition of the L2 cache interface.
• Like the Pentium family, the Celerons offer multiple branch prediction, data-flow analysis, and speculative execution.
