The Pentium III from Intel is a sixth-generation CPU targeted at the consumer market.

Desktop processors

"Katmai" (250 nm)

  • 9.5 million transistors
  • All models support: MMX, SSE
  • The 'B' suffix denotes a 133 MHz FSB
  • The '80525PYxxx512' number denotes an OEM CPU while the 'BX80525xxxx512' or 'BX80525xxxx512E' number denotes a boxed CPU
  • The L2 cache is off-die and runs at 50% CPU speed.

"Coppermine" (180 nm)

  • 28 million transistors
  • All models support: MMX, SSE
  • The 'B' suffix denotes a 133 MHz FSB when the same speed was also available with a 100 MHz FSB.
  • The 'E' suffix denotes a processor with support for Intel's Advanced Transfer Cache [1] in Intel documentation; in reality it indicates a Coppermine core when the same speed was available as either Katmai or Coppermine. The 'E' suffix was not used on speeds faster than Katmai was available on, unless the 'B' suffix was also present; but all Coppermine CPUs have the Advanced Transfer Cache.
  • The L2 cache runs at 100% CPU speed

"Coppermine-128" (180 nm)

Xbox's Coppermine CPU

A custom Coppermine-based Pentium III version was developed for Microsoft's Xbox game console. The only significant change was that the chip lost half of its L2 cache, dropping it down to 128 KB. Unlike the Celeron Coppermine-128 variant with the same size L2 cache, but reduced 4-way L2 cache associativity, Xbox's Coppermine core kept all of its 8-way L2 cache associativity from the Pentium III. This means that the Xbox CPU's L2 cache is more efficient than Celeron's. The Xbox CPU was manufactured onto the same Micro-PGA2 packaging as notebook chips, but in a BGA (ball grid array) format.

  • All models support: MMX, SSE
  • The L2 cache runs at 100% cpu speed
