Hey guys I got a quick question. I've got a DEC Venturis 466 and according to the manual it can accept a pentium overdrive 83mhz cpu. I opened it up tonight and it does indeed have a ZIF socket with extra pins available around the outside of the AMD 486-dx 66.

I guess my question in can it really accept an Intel cpu even though it shipped with an AMD? Was this really possible back then to interchange Intel and AMD cpu's?

Heh well I'll be damned...This DEC just keeps surprising me with its upgradability especially for an OEM system. So I guess my next question is are there any advantages to upgrading to that particular cpu? I've noticed it is rather pricey on ebay....

Not really 😀 The FPU will be a lot stronger, the integer performance will be higher. But you will probably end up playing the same games on it that worked well on DX2-66.

If you want a Pentium, buy a complete Pentium machine, it will be cheaper if you take some time. Pentium Overdrive is more like a CPU for aficionados who already have every basic retro setup they ever wanted.

Basically if it runs in write through mode, and/or if the L2 cache on your motherboard doesn't work with the chip it's not worth the trouble. Go with the am5x86-133 and overclock to 160. It's the fastest chip on the list you can realistically get your hands on (unless for some reason you need a real Pentium FPU).

Sure, the first generations of AMD CPUs (and most other x86 clones) were designed to be drop-in replacements for Intels. AMD's 386 and 486 were pretty much exact copies of the Intel chips. Their Pentium-class CPUs ran on the Pentium's socket 7.
The Athlon was the first AMD CPU which had its own sockets and chipsets.
