The rare / unusual CPU club - Page 3

Wow, so many posts since I was last here!

Hi, harishgayatri, welcome to the thread

The C3 was already mentioned, we sort of agree that it's not very rare, but it's unusual, so I added it to the list.

As to the 486DX2, well, I just have one thing to say: you've got a great CPU right there , but unless that signing on the CPU is from a celebrity, it's not rare at all. The 486 DX2 66MHz was the best selling CPU of the early nineties!


Fully agree. I'm just asking for a photo right now, but if people also want to put a CPU-Z validation (those who can hehehe), they're welcome. Depending on the model (if it's very rare, for example), it may be useful for the poster to put a small piece of paper next to it so that we are sure.

A Core 2 Duo E8800 ? Wow, I have already seen a few people in the forums with E8700's but I had never heard of that! That would have been legendary, as legendary a name as the 8800GT

That is some nice patina that CPU has hehehe, looks like an old coin

I don't think they are rare tough, but good find. Keep it so you can tell your grandchildren "I used to play and do work on this back then"

Hey Hyoketsu! Nice find, but no cigar Those were pretty common.

The first Pentium was actually released in 1993, with 60 and 66Mhz speeds. I have a bunch of paper magazines from back then (I'm actually starting to think about making a thread of "old news", sort of like a timeline, told by magazine covers, of how we got where we are today).

These two initial Pentium models ran hot (for the time), and the 60 Mhz version wasn't even as fast as the 486DX4 100Mhz (the 66Mhz model was probably more or less on par). These two were the ones that had the FDIV problem that Intel initially didn't want to acknowledge. They later agreed to exchange the faulty CPU's with revised ones.

The Pentium only really took off around 1995, when the 75Mhz Pentium not only ran faster than the fastest 486, but was also cooler running, and bug free. The 75 Mhz Pentium was the real starting point for the Pentium when it comes to mass market. Then came the more expensive 90 Mhz Pentium, and a little later the 100Mhz Pentium. These were all available in 1995, with 133, 150 and 166 Mhz models coming in 1996.


Oh... you could fetch some of them for us, could you ?


Wait, what ? I did a search for that, and the info is a bit confusing. Can you tell us a bit more about that CPU ? Speed, FSB, platform ?

I have a Cyrix 5x86 (formerly a 486SX2 66Mhz) that (I think) is fully working. Will be checking it out on a few days. Maybe I'll do a video to show you guys!


I bought a P3 Tualatin 1.4 Ghz today! Hooray! I don't have a board, so for now it's for collecting purposes only, but I'm so happy Always wanted one!

The Pentium 3 were also held back by the FSB being slower. Oh well, Intel had a great chip. If only they had paired it with the P4's higher FSB and DDR ram, we would have had the Core 2 lineup much sooner

I do love the P4 line though. With it's mistakes (Prescott) Intel learned how to fine tune the best balance between performance, clockspeed and pipelines, and the results are showing now with Sandy Bridge

Post pics!

Nice! Not exactly rare, but nice! Still useful as a PC for downloads and general office use.

You do ? Photos! Photo! Photos! Hyoketsu, if kenolak ever decides to sell, we're going to be having a little discussion between us

Ohhhh, Tandy's! My first PC was a Tandy! A laptop! It had an 8088 CPU, a 20 MB HDD, 720k low density 3.5 floppy drive, and a white/blue widescreen monitor. Came with it's own OS, with a nice GUI and everything! Weighed about 5 Kg tough!

You can say that again! But let's face it, our 3.4 Ghz Northwoods are pretty good. Ok, I am lying to myself now. I want the EE

Hmm, DX4 66 Mhz ? You mean DX2, right ?

Those two 486's were pretty good sellers at the time.The DX2 being the best bang for the buck and then the DX4 also being the best bang for the buck when the Pentium was already starting to come into the mainstream.

I'm not sure how rare those Sparcs are. Can you or anybody more experienced with those shed a little light on the matter ?
