| You never know when someone will find a stack of trays of previously uncommon NOS chips in a cupboard somewhere. The sharp rise in available quantity will cause prices to drop. |

For exemple, a lot of P54 or MMX are popping by trays on Ebay,
Buying 100/120$ a rare spec of those today seems crazy and really risqued, moreover when they have a big timeline.
At the reverse, 386/486 are becoming more and more rare, and some rare spec are worth less than rare pentium...
So i'm trying to figure out what is safe from trays and other not... |

The last tray I can think of is a 486 from xhoba with SX884, and it's a 1994 chip
Don't think we'll wee a tray of A80386-12 any time soon lol.
The hard part is to determine if middle frequencies will pop such as A80186-6 or AMD PGA 186/286... |

I heard, same with Voodoo. A friend told there were no equivalent.
But cpu for retro gaming ? Is there an equivalent of PODP5V83 in Socket 3 ? |

There are different markets. Collector's market, retrogamer's market, user's market...
For the collector, when they see something unusual, they can put high price for it. After, it will depend on experience on collector. Collector with little experience will find something unusual very often... And will pay and pay for things not so rare. That can explain sometime abnormal prices.
Retrogamer's and user's market will look for more powerful cpus on a platform. So for socket 3 this is PODP5V83. For Socket 3, it will be AMD DX5s and so on. This explain why those cpus tend to be more pricy. Because they have a additional value.
Anyway, looking at ebay from time to time is not a good indicator. You have to look for a big period, to average the prices, which is quite hard to do if you follow lot of kind of models....

am5x86-133 should never be rare. They made loads and loads and loads of them until at least 2002.
PODP5V83 probably wasn't manufactured for very long, but almost nobody bought them, so tonnes survive in shrink wrap. |
