How much would you pay for a Dual 7448?

A couple of years ago I sold two single-CPU 1.8 GHz 7447 upgrades for the Cube. One sold for 170 bucks, the other, which was still shrinkwrapped, sold for 300. The point is: you can't compare second-hand prices for these two items because one is much rarer and more sought after than the other.

Found a listing where I live for a NewerTech Dual 1.7 7448, priced at ~ $170USD.

Would it be a good idea to get it, then sell it for a higher price, or should I get a QS and use it myself?

How much would anyone pay here for one?

In 2016 I believe, I paid $350 on eBay for a dual processor 1.8Ghz Sonnet.

Considering the fact that this is a dual in the same class, it's being under sold by about $200.

Considering the fact that this is a 7448 DUAL, it's being under sold by about another $100.

And finally, it's NEWERTECH! Other than Sonnet, this is the best you can get. And ONLY NewerTech did 7448s.

For myself, I'd go as high as $450 on that and I KNOW I'd be outbid by someone else.

Just for reference, in case you caught this message through the main forum page or 'new posts' page…

OP's question is applicable because there is still a community on MacRumors that uses PowerPC Macs - and this thread is in that forum.

I would personally buy that CPU for $170. On ebay it would probably go for $1000. I suppose the honest thing would be to let this guy know what he has. If you don't want it, you could buy it and re-sell it here or on ebay to someone who would appreciate what it is. It would definitely be a shame for it to go in the trash (which is where I would put a macbook).

I have bid over $550 on eBay for such an item and was outbid by $200 within minutes, if not seconds. The final price, if I remember correctly, was close to, or over, $1,000. I am still looking for such an item.

As a matter of history, I recently worked for one of the designers of the Apple IBM Motorola PowerPC chips. After working for Apple, he was one of the top people at Newer Technology. The Newer Technology MaxPower 7448 was not built by the original Newer Technology company, but by Other World Computing, which bought the rights and assets when Newer Technology went out of business. One of the other people in the company where I worked was also at Newer Technology and confirmed what the first fellow said.

A couple days ago I ordered a couple of network cards powered by 7448s just in case the one on my Matrox board is dead or something goes wrong with desoldering. Total came out to just over $100, and now I will have three in my collection. :)

In other news I ordered myself an MC7447B. Thing is tiny.

Personally, I would only pay $125. But, I can see people paying as much as $250-300. I just personally would prefer slower-clocked 7457s with max cache over higher-clocked 7448s without L3, unless they're at something crazy like 2.4 or 2.5.​

Where would you see the strengths and weaknesses of each respective choice there? For example, with popular PPC applications that people tend to throw on Leopard.
 
If I found a dual 7448 for that kind of money, I think my wallet my catch on fire from how fast I pulled it out of my pocket.

IMO, this is an easy $400+ CPU card. I've bought two single 7448 upgrades, one loose and one in a computer, and paid north of $200 I think for those.

I payed around $300 several years ago for a new in box Sonnet dual 1.8, which I think a lot of folks here will consider the sort of high water mark for G4 upgrades for this class of system that can actually(somewhat) easily be found. That wasn't an unusual price, and you'll see a few other folks in this thread saying they paid around that much for the same upgrade.

The Sonnet is a 7447a upgrade, and by every metric I can think of, clock-for-clock the 7448 is at least equal and in many cases better than the 7447.

Of course we won't talk about that Gigadesigns dual "1.8" I bought from @eyoungren ...that made its rounds here before it landed with me.

That thing wouldn't fit in my QS without blocking a ram slot. And you had the ability to grind the heatsink to a near mirror finish. I was glad you were able to make it work.

I did get it to work, but I still couldn't get it to 1.8 reliably, or not without raising the voltage more than I was comfortable for long term use.

@LightBulbFun has a better memory than me. I don't remember if I got it to 1.6 or if I stalled at 1.42, but wherever it was it was absolutely rock stable.

I still wasn't able to get the heatsink as pretty as my Sonnets, but lapping/polishing it made a huge difference considering that you could see and feel the "waviness" from machining that they'd left behind. I wish I'd thought to weigh it before and after lapping, but it wouldn't surprise me if I ended up taking 1-2g off the total mass of the heatsink just getting rid of that part of it. I remember spending a long time on 80 grit sandpaper, and normally on something like this I'd not use anything more course than 300 grit. IIRC, I started at 300 and it wasn't really even touching it.

Giga was definitely struggling at that point. I have some older Giga CPUs-one I think a more traditional 7450 or maybe 7455 and then another 7447. Both of them are great and very stable even OCed from their rated clock speed. This dual 1.8 was just...rough...and not from anything you or previous owners had done.

Something else I think that's worth mentioning is that I think all the high speed 7447 upgrades are overclocked. I don't think anyone but Apple was ever able to get the 1.5 and 1.6ghz CPUs from Motorola. Most of them, including the infamous Giga, have 1.25ghz rated CPUs. My Sonnet dual 1.8 has 1.42s, and I'm not sure if that was a result of Sonnet being willing to pay more(and charge more) for the CPUs or if they had some special relationship that let them get CPUs others couldn't. I think that it shows in that no one ever worries about the stability of the dual 1.8 Sonnets.

I believe it was 1.6 you had it stable at. 1.7 was a crapshoot as I recall and 1.8 just wasn't going to happen.
