Intel Celeron Processor

• Overview of the Celeron
• Introduced in 1999
• Equipped with MMX. Newer versions with SSE.
• Originally based on Pentium II
• Current versions use core similar to Pentium III

3
Intel Celeron Processor

• Original Celeron
• Slower than other chips of the time
• No L2 cache
• Lacked casing
• Easily overclocked
• Inexpensive

4
Intel Celeron Processor

• Later Celerons
• Moved to Socket370
• Based on Mendocino core
• SSE instruction set
• Half the L2 cache as the PIII
• Current Celerons
• Based on Coppermine core

5
Intel Celeron Processor

• Old 66MHz FSB
• 500, 533, 566, 600, 633, 667, 700, 733, 766 MHz
• 100 MHz FSB
• 800, 850, 900, 950 MHz
• 1.0, 1.10, 1.20, 1.30 GHz
• Move to 133MHz FSB

Benchmarks
11
Intel Celeron Processor

• Overclocking the Celeron
• No L2 cache
• Pentium II cores used
• 66MHz bus / 100MHz cores
• Current Celerons have locked clock multipliers.
• FSB must be changed to overclock the chip.

12
Intel Celeron Processor

• Risks of overclocking
• Increases heat production
• Breaks down connections
• Other components may not work with faster bus
• DESTROYING THE CHIP!!!!

13
Intel Celeron Processor

• Mobile Celeron
• Voltage difference
• Reduced power consumption
• Variable power consumption (Intel SpeedStep)
• 0.13-micron process
• Smaller chip size

14
Intel Celeron Processor

• The Future of the Celeron
• Chip will still be produced
• However.
• Intel is focusing its marketing efforts on the
  Pentium 4 for desktops and the mobile Pentium 4
  for laptops.
