New PowerPC Magazine.....

Compare transcoding video on a G3 to a G4 and get back to me :D

Why do you think I had an "lol" emoji at the end? It was a joke. The G4 had the Velocity Engine, whereas the G3 did not since it was an older generation chipset. It came with bigger processing benefits over the G3.

Crazy thing though... the G3 and G4 shared the same front side bus speeds, which really kneecapped the G4.

Yep, as I noted here IBM implemented an Altivec-Lite solution for the G3 variants in the Nintendo Gamecube, Wii and Wii-U because otherwise they would've struggled in many areas.

That's interesting. Does it apply to all G4 models - even if you've upgraded the CPU with a Sonnet etc?

I will say that my 900MHz G3 is pretty fast compared to the slower G4s. It actually scored a lot higher in MacBench (OS9) then my 867MHz 12” G4 which I thought was odd.

Not to be a killjoy but I think it is only fair to point out, having just seen the opening post, that MacbookProdude lives in L'viv, which has been bombed on more than one occasion within the past month. I have relatives there and in the area and the males among them have been mobilised. I know he can get a bit excitable at times and must have said something recently that I have missed, hence his enforced absence, but cut the bloke some slack here.

It was a reference to him being suspended (for what, I don't know but nothing inflammatory in this forum) and was chosen in the same vein as the others - I 'd have hoped it would've been interpreted as such - even by him when he's back on the forum.

I know. Just under the circumstances, the wording is a little unfortunate, maybe.
 
@Dronecatcher So when can we expect the May iteration to come out? Or is the MacRumors PowerPC Edition magazine a bi-monthly occurrence only?

Because I'm sitting on the edge of my seat waiting to know just how many more monitors @eyoungren has undoubtedly set up in the weeks since last month's publication.

EDIT: Scratch that ... my contracted ninjas have just leaked to me the following photo of @eyoungren's house circa two days ago:

I think this would make for a great two-page story. :)

What's the theoretical limit of multiple displays for a PPC Mac? Something like 12?
Click to expand...
When using Mac OS X, you're limited to GPUs with two outputs. Newer GPUs that can drive more than two monitors (AMD Radeon HD 5000 and newer, NVIDIA GeForce 600/700 and newer) lack drivers for Mac OS X on PPC.

So, it's the number of GPUs (which is basically the number of PCI/AGP/PCIe slots the Mac in question has, assuming you can physically put a GPU in each of them and don't run into heat and/or power issues) times two.

However, there are devices like the Matrox DualHead2Go and TripleHead2Go: these allow driving two or three monitors from a single output by making multiple monitors appear and behave like a single ultrawide monitor, thereby neatly expanding the aforementioned limit. Several of these devices can be connected to the same computer.

Theoretical example (no idea if it actually works like that):
  • A Late 2005 PCIe G5 can have 4 GeForce 6600 GPUs (with one dual-link DVI and one single-link DVI output each) installed. Each GPU is capable of driving 2 monitors, bringing the "official" maximum to 4 × 2 = 8 monitors.
However, if you were to connect...
  • a Matrox TripleHead2Go to each dual-link DVI port, each driving 3 monitors (the limit would be 1280×1024 per monitor) and
  • another Matrox TripleHead2Go to each single-link DVI port using a DVI-to-VGA adapter, each driving 3 monitors (the limit would be 1280×1024 per monitor),
you might be able to have 6 monitors per GPU, possibly bringing the unofficial maximum to... 4 × 6 = 24 monitors.

The Mac, or rather Mac OS X, would see "only" 8 ultrawide 3840×1024 monitors due to how these devices work.

I just want to add that you also have to watch the amount of VRAM you use, Leopard’a limit is something like 1.5 GB? Maybe less? This is why the 6600LE exists for the pcie G5, there’s only 128 MB VRAM on them. You can put up to 8 monitors on any pcie G5 by adding 3 of the 6600LE, regardless of your stock video card.

I would say the limits you specify also might be a consumer limit. I say that because, at least what I've seen for PC/Windows, there exists out there those giant jumbotrons you find in stadiums and outside shopping malls, etc. Those are actually linked displays that are built section by section and act as one giant display - controlled by software that runs on a PC/Windows.

Yeah, that's…yeah. SMH! :D

I won a bulk auction of 30" Cinema Displays. /s :)

Most definitely. I mean, ATI/AMD GPUs can drive 6 displays each. Depending on how many you can stuff into a Mac/PC, you may be able to have, say, 36 or more monitors on a single system.

...or multiple PCs networked together, which, I guess means the sky is the limit.

Below is kind of what I'm meaning.

I'm not trying to highlight the Windows stop errors, just trying to show that the screens are linked and the stop errors show that.

LOL!

How It's Made (a cable TV show here in the US that shows you how stuff is made) had a show a few years ago on those giant outdoor screens. That's cool in itself, but while I was looking around I ran in to a website that produces the software that links all this stuff and keeps it in sync.

If this planet ever becomes one giant spherical view screen it won't be because of me. Well, probably not. :)

That got me thinking. I wonder if the PCIe G5 would work with PCIe expansion chassis. You could potentially drive thirty two GPUs.

P.S. That computer definitely needs a mouse cursor desktop background. I could just imagine trying to locate the cursor on all those screens.
