It was a Sawtooth/1.8ghz machine so that covers the older hardware generations but I need to solve the gfxcard issue first
Please no 7448 cpucards as they aren't supported in MorphOS yet, only 7447a,7455/7 cpus.
If you wanna be secure look for MDD/F800 configs because that's what I have here.

Thanks for the clarification
Is support for the 7448 likely to come in the future? It seems to be so rarely used, maybe it's not worth the bother?

> maybe there hasn't been the demand as the 1.8Ghz Sonnet is duel cpu.

By that logic there wouldn't have been demand for single 7448 at 2.0 GHz for older PowerMacs G4 neither. There are dual 7447A/B at 1.8 GHz as well as dual 7448 at 1.7 GHz for the older systems.

Hey guys can I ask you what in the world you are going to need anything more than 1ghz with morphos other than encoding video? Just would love to know what you guys do with all that cpu power?

Magnetic: for me it's just a satisfaction :)

As I haven't seen a 7448 cpucard on ebay.de it's unlikely. As far as I know the difference between 7447/745x and 7448 is a bigger L2, faster busclock(which can't be used in an Apple as far as I know) and a faster Altivec unit so not that much for most MorphOS code.

Prolonging a short dick - what else?

Dunno, probably 1080 hd vids work on a 2 GHz maschine, but the ram speed could stop it. Anway, in general I think there will always be demand for fast maschines (though I personally also like the low end systems like my Efika).

Do you think someone from Morph team can do a rough benchmark comparison with a Peg 2 and a Quicksilver or something? I'm wondering if I should sell my peg2 and go powermac...

the memory is faster i'm sure and cpu cache but real world wise is it worth the upgrade?

Also, is dual cpu supported??

> the memory is faster i'm sure and cpu cache

CPU cache is not necessarily faster with a PowerMac G4 compared to Pegasos II G4. It depends on the specific PowerMac G4 model and upgrade status. I guess that non-upgraded Quicksilver and older have a slower CPU cache than Pegasos II G4.
Similar regarding memory throughput (which is probably not that dependent on upgrade status): PowerMacs G4 older than Quicksilver have lower memory throughput than Pegasos II G4 I'd guess.

> is dual cpu supported??

Ruud already gave the answer in this very thread: MorphOS is going to support dual CPU configurations but utilizing only one CPU.

@magnetic, I would sell your Peg2 quickly to someone that wants it because it can run both MorphOS and AmigaOS4.x. With the prices of old G4 PowerMac's being so low, you could probably get enough money to buy one AND upgrade the CPU to a 1.8GHz, or 2.0GHz third party accelerator upgrade with the money you can get for your Peg2.

I think you can probably get a QuickSilver PowerMac for between $60 to $120 and the later MDD models aren't much more than that, but then you also need to figure the cost of a new MorphOS2.5 license when it is released as you can't transfer your Peg2 license to the PowerMac. Still, $200 to $375 for a fast MorphOS2.x system and license is a great deal. I am loving my 1.5GHz G4 MacMini that I am typing this on.

I saw one G4 PowerMac on eBay (not .de) that was advertised as an upgraded to 2.1GHz G4 CPU (single I think) a few days ago. I don't know if the auction has ended so I may not be able to find it again. I think it was the QuickSilver model.

Edit: Nice to see you posting here Ralph. Can you say if the next release of MorphOS, version 2.5 will have support for the G4 eMac and PowerMac models? Also, are we looking at more than, or less than six months of work before MorphOS2.5 is likely to be released (no firm commitment required, just an educated guess)?

The extra CPU speed is good for those people that want to double, or triple boot their systems and only have one computer at their desk instead of two or three.

But that's a strange one:
- no mention of exact upgrade type (AFAIK 2.1 GHz didn't exist for any PowerMac G4 model)
- bus speed of 167 MHz and RAM speed of 333 MHz would indicate FW800/MDD model, for which the fastest upgrade I know of would be (dual) 1.8 GHz
- "Processor Manufacturer: IBM"

7448 1.8 GHz card for 350 USD:

Yes, that sounds right, 1.8 dual processors or a 2.0 single, but aren't both those options overclocked to reach those speeds?

I guess they are. Freescale specs the 7448 at 1.7 GHz max.
