Sort of. The processor is an Intel Coppermine-core processor that runs at 733 MHz. It is soldered onto the motherboard in BGA2 fashion, similar to that found in many older Pentium III and Celeron laptops. The processor can't be considered a Pentium III because it has half the L2 cache of a normal Pentium III at that speed and FSB. It's not a quite a Celeron either, though, since no other Celeron in that layout had that high an FSB (133 MHz in the Xbox vs. 100 MHz for other mobile Celerons. It thus sits somewhere in between in terms of performance.
Architecturally, it is no different than a Pentium III, though. Linux applications written for the Pentium III can run without modification on the Xbox.
Yes.
The Intel Pentium III.
The Pentium III was a processor found in many computers, both desktop and laptop, in 1999 and early 2000s.
Yes. The GA-6BXC can support any Slot 1 Intel Pentium II or Pentium III processor. For the faster Pentium IIIs, you will need to purchase a "slotket" to convert a Socket 370 processor to the Slot 1 interface.
It is equivalent to Pentium III- and early Pentium 4-based Celerons.
SSE was first used with the Intel Pentium 3 III.
The Intel Pentium III was released on February 26, 1999.
Yes.
No Intel processor bears an official branding of a name beginning with 'T'. A few processor core codenames have begun with T, such as Tillamook (the mobile version of the Pentium MMX) and Tualatin (the final revision of the Pentium III).
The Intel Pentium III was a line of 32-bit processors first released by Intel in 1999. They introduced the SSE instruction set for better multimedia performance, and the controversial unique processor serial number (which was removed in the last revision).
No. It is a higher-end version of the same processor, with a larger amount of L2 cache. It cannot be used as a replacement, since they use different slot / socket types.
Possibly. "Celeron" doesn't refer to any particular processor. They are cost-reduced versions of the Intel Pentium II, Pentium III, Pentium 4, Pentium M, and Core 2 Duo. Assuming that your Celeron is based on a processor that is faster than the Pentium III, you shouldn't have any problems. If yours is based on the Pentium III, check the clock speed. A 1.2 GHz Celeron, for instance, is probably fast enough for a game that requires a 1 GHz Pentium III.Other factors, such as the graphics card of your system, may also be important.
