There is no "Pentium R" processor. Knowing this, the biggest difference is that the Pentium III exists and the other does not.
The Pentium III was a processor found in many computers, both desktop and laptop, in 1999 and early 2000s.
The Dell Precision 410 workstation was equipped with either a Pentium II or a Pentium III processor, at a speed between 350 and 700 MHz.
In some cases, yes. If the BIOS of the motherboard has the proper microcode updates to control the processor, and the FSB (front side bus) is at a high enough rate, you can install a Pentium III processor on the older board.
Yes.
The Intel Pentium III.
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.
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.
I've yet to encounter an AT motherboard that supported a Pentium III processor. All the same, it is possible to run Solaris 10 on a Pentium III computer. You'll need at least 256 MB of RAM, however.
It is equivalent to Pentium III- and early Pentium 4-based Celerons.
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.
SSE was first used with the Intel Pentium 3 III.
No, the Pentium 3 and Pentium 4 are not only samples of 2 completely different architectures, but also use a different socket so a change between the 2 on the same motherboard is impossible.
