alt Hacker NewsThe Celeron 300A was the one most folks would go after for this. I don't recall the exact retail pricing at the time, but they were more or less guaranteed to overclock to 450mhz and be fully stable. Typically retail pricing could be had at discount to the published wholesale pricing within a couple months of release due to how quickly the market moved back then.
These were competing with PII processors in 1998, and for folks who wanted to go dual CPU it was the way to go.
There was a whole cottage industry of folks modding these CPUs as a small side hustle for people who were not comfortable with soldering onto CPU pins if you wanted to put these into a SMP system.
Performance really did mostly scale linearly with clock speed back then - but for a single CPU. The dual CPU setups were not nearly as efficient due to software not being as multi-threaded as it is today. The big win were folks with two monitors (rare!) who could run apps on their second monitor while playing games on the first. Typically you would only see frame-rate increases with CPU clock - and of course the very start of the serious 3D accelerator (3dfx, nvidia, ATI) scene back then.
It was certainly the golden age of enthusiast computing - especially for gaming.

Yes but they got hard to find in a hurry once word spread. I had two 366s in my BP6 overclocked to 550 but IIRC I had to buy a few to find two that were stable at this frequency.

No modifications necessary with the BP6.
Ahh, the 300A and the BH6. Such a combo.
I bought two to have one gaming machine and one coding/hacking machine (including learning about networking now that I had two computers). Geek heaven.

When Intel switched from Slot 1 to Socket 370, there was a market for "slocket" adapters that allowed Slot 1 motherboards to take Socket 370 CPUs. The best of these adapters worked out a way to re-enable SMP on Celerons by tweaking the pin layout to disable the lock Intel had added. What made the BP6 so popular is that it was a native dual-slot Socket 370 motherboard that had this modification built in so it could use unmodified dual Celerons out of the box.

Even if you only had one monitor, multitasking was FAR better on a dual-CPU machine than on a single CPU system. For example, if you were extracting a ZIP file, one CPU would get pegged at 100% but the system was still responsive due to the second CPU not having any utilization. If you use a dual-Celeron BP6 system, it's a much nicer and more modern feeling experience than using a single-PII system even with the faster CPU with more cache.
