A little history,
The very first start of Socket370/Slot1 processors was the Slot1 Pentium2 233MHz processor. Then came the 266~300MHz versions of the CPU.
But then Intel decided on a value based CPU for the first time and it had came to be the Celeron @ 266MHz. Then 300MHz celerons soon came. But Intel was getting edgy on how the Celeron core was not stable enough and did not feature enough floating point units. So, Intel had built a complete revision to the core and called it the Celeron 300a. From this point, the celerons had began to ramp right up to 466MHz on this architecture.
The Pentium countinued to ramp adding another 33MHz to bring it to 333MHz, then Intel decided a 100FSB was need. Then 350~450MHz Pentium2 CPUs came about. The Pentium2 @ 450MHz lasted forever, about 6months before the Pentium3 showed in March 1999.
At the time that all this history was being made, all this CPUs were powered by the FAMOUS BX chipset! The LX chip was there but died soon after the 100FSB processors came about.
Anyways, Celerons finally got FC-PGA @ 400MHz and this started to countinue right till 533MHz. Intel finally launched a new Celeron2 core which was dubbed Coppermine-128 which had some potential.
The Pentium3 meanwhile ramped from 450~650MHz on 100MHz FSB. Then came Coppermine, a CPU core that will go down in history. The coppermine core gained a 133FSB and ramped right till 1000MHz. A 1133MHz Coppermine was built but never lasted due to some failures and limitations that the architecture had.
Meanwhile, the Celeron2 had ramped to 700MHz on 66MHz FSB, while at 700MHz, most people thought Intel was playing a joke of releasing a processor of 700MHz crippled so harshly at a 66MHz Bus
.
The Pentium3 Meanwhile had came to a hault, no new technologies were being implemeted and a final Tut core would bring another new life to this already aging chip. The Pentium3-S is one powerful CPU that scaled from 1000MHz~1533MHz as of April/May 2002. @ 1533MHz, this CPU could potentially outperform a 2.2GHz Pentium4 in many applications.
Finally, The Celeron had gotten 100MHz FSB and soon ramped from 700MHz~1100MHz. It had taken over 8 months before Celeron-T had arrived. Initially @ 1200MHz, the Celeron T would squish even a 1GHz Pentium3 with a 133FSB, impressive and more over a 1.2GHz Pentium4 maxed.
The Celeron-T also scalled back and produced 1000a, & 1100a versions of the CPU. The Celeron-T CPU had soon ramped from 1000MHz~1533MHz.
Conclusion:
---------------
Intel Pentium(2-3) Architecture based on Slot1/Socket370
233MHz~1533MHz
Intel Celeron(1-2-3) Architecture based on Slot1/Socket370
266MHz~1500MHz
So there you have it, the end of Socket370, which STILL TODAY CAN BE POWERED BY A BX chipset!! Thats gatta go into the history books of technological advancements.
