It's Tuesday so it must be time for some faster chips.

Intel has rolled out two new Celeron processors running at clock speeds of 766MHz and 733MHz.

Rival AMD still holds the speed crown for budget PC chips after releasing an 800MHz version of its Duron processor last month.

However, the supply of Duron systems is limited, and the processor probably won't arrive in high volumes until the first quarter of 2001, AMD spokesman Drew Prairie said.

Like previous Celerons, the latest chips feature 128KB of on-chip Level 2 cache memory and a 66MHz system bus. They are being manufactured using Intel's 0.18-micron manufacturing process.
