    Black Pentium Pro CPU's

    I came across a few of these while dismantling some old servers. They were state of the art back in the day!

    probably going to be black fiber, do you know what these came out of? the fiber pros were supposed to be low power consumption for workstations and yes,,, even laptops (can you imagine?)

    It was a workstation of some kind. I think IBM, but I'm not sure.

    I found next to nothing on these. I've been looking, if you want to be sure what your returns are you will have to contact a buyer, someone who buys these will know if they are black fiber or p pro.

    I only have 10 of them, so it's not a big deal. I was just curious.

    Intel Pentium Pro 200 1 MB - GJ80521EX200 1M / BP80521200 1M

    I think this is yours, probably going to go as black fiber. No gold caps on these.

    These are real Pentium Pros, the only difference is that they do not have the pretty gold cap.

    Pentium Pros with the gold cap, typically yield between .3 - .34 grams per CPU. The majority of that being the gold planted pins, as there is far more surface area, and the gold plating was over Kovar which is kind of spungy/porous. Your particular chips came out at the end of the Pentium Pro production, when they were almost exclusively used for servers.

    The Pentium Pro came out in 1995 originally. It's replacement didn't come out until 1998. It was one of the longest produced CPUs.

    The gold cap on the earlier model is a 200 MHz Pentium Pro with a 512 KiB L2 cache in PGA package, the one you found in the servers you mentioned is a 200 MHz Pentium Pro with a 1 MiB L2 cache in PPGA package.

    But I imagine you really want to know the gold content more than anything else. I have processed a lot of Pentium Pros, and have the data right here in front of me, so thought I would post it for your benefit.

    Your chips, although not having as much gold content as the earlier Pentium Pro's, are still high grade and bear a lot of gold considering we are talking about gold plating. A good refiner should recover between .2 - .24 grams of gold per CPU.

    The gold plating usually found on the top of a Pentium Pro is usually less than .1 grams, that ends up being about $3-$4 dollars worth. In other words, you don't loose that much by not having the gold cap. Still a very nice find, indeed. Congrats, it's not often you will find Pentium Pros anymore.

    You said it! These are extremely RARE CPUs as they came with double the on-board l2 cache as most Pentium Pros. In fact, until the last few years, there were no cpus with this much on-board l2 cache made by Intel.

    I hope you sold these out to a collector vs scrapping because they were worth at least $20/ea to me, and I have 7 systems that I could have put them into. A quick search shows retailers charging almost $100/ea!

    There STILL isn't a cpu made with that much cache for a single core.

    Yep, not for a single core. And the PPros could execute 32-bit better than 16-bit code too. If the processor speeds were faster, these would have still be used today on lower end systems.

    The Pentium Pro could be used in a dual-cpu configuration on certain systems that had capable motherboards. I own several of these, but the hardest part has been finding cpus like these with the large l2 cache. Something to keep in mind as scrap won't pay as well as someone that has a use for it.

    I still have them. If you notice the serial numbers in the bottom left corner. There are two matching sets of four and the bottom two are close.

    Whew! I was afraid you had these toasted. Glad you hung onto them. Very neat set with sequential serial numbers!

    If you ever want to get rid of these, I believe a have a good home for them. I have 7 IBM Netvista systems that came with PPro 180s/200s. They were also dual processor capable, so there's another pga for a second processor to be installed. I just don't know if they'll need a separate voltage regulator too, which would have to be something else I'd need to do the upgrade.

    But dual core even at 200mhz with a large l2 with 128MB of ram should be enough for a decent win2k or xp setup.

    These are not extremely rare CPUs, no where near it. Are they collectible? Yes and definitely worth more than gold but no not rare. When you call something Rare, it's pretty hard to find and definitely brings a higher price tag. Just to mention one example, HP`s first CPUs that had hand written timings and other specs used in average hardware. These CPUs were faster than all of these listed, Intel 4004, 4040, 8080 and Motorola 6800, there are more that's just a few to mention. These CPUs were the longest manufactured and so far advanced in every way back than but so rare to find now. Prices ranging from $100 to $5,000 and even $10K depending on which model you have and condition. That's rare
