I included a PIII 500 in these tests as well.
Celerons will be faster clock for clock if you're also using the same FSB as said CPU, so that's 66MHz for early Pentium II CPUs and then 100MHz for the later ones. But yes, a lot of people bought the Celeron 300A, easily clocked it to 450MHz and basically had the fastest CPU available for a while. The fastest CPU at the time was the Pentium II 450, but it would actually be slightly slower for most tasks, not to mention cost roughly 4x times what the Celeron did 🤣 .
I've noticed an interesting issue with K6+ platforms that I haven't seen mentioned elsewhere, other than fellow member Skyscraper. I've seen performance with 3Dfx cards really plummet even on K6-III+ 550 and faster CPUs of the same family. This seems to affect both D3D and Glide/OGL and also any card I've tried, be it V2 SLI, Voodoo3 and even Voodoo5. I once had this issue on my GA-5AX and managed to resolve it by using a V3 AGP instead of a PCI version and didn't really give it much thought after that. However, even on a P5A-B I've seen this manifest with all of the aforementioned videocards.
To give you a perspective, Quake 2 will produce roughly 50fps, regardless of resolution, on Demo 01 and both V3 and V5. I noticed this issue around July while benchmarking Forsaken and seeing my FPS plummet at 640x480 with a V5 from ~160FPS to ~80. I've tried clean installs, different OSes (of the 9x family though), different drivers, different BIOS settings and have yet to pinpoint it. And to be honest, I got kinda pissed off about it and stopped paying attention. If anyone has ever noticed anything like this before, I'd love to hear your thoughts. I might start a new thread to raise awareness/see if we can somehow resolve it. We can safely say this is an Aladdin V based problem, hopefully it doesn't turn up on MVP3 boards.
