IBM's new development platform for the PPC750GX is now available. The board is based on Marvell's Discovery III (MV64460) chipset (which is software compatible with the Discovery II chipset used in the Pegasos II board) and supports a 200MHZ FSB and DDR400 memory. The board is a dual CPU board and also has four 64bit PCI/PCI-X slots running at 133MHz.
(Thx to www.morphos-news.de for the info)
Will we see a new Pegasos for the end of the year ? Let's hope!

The next pegasos is said to be based around the IBM PPC 970 CPU (the "G5") and the corresponding Marvell **970** chipset with IBM's high speed Elastic Interface Technology. The Pegasos III will NOT be based on the Discovery 3, and using this chip in the current Pegasos design would at best only offer a minor upgrade to the current Pegasos 2 and would probably not be worth the effort.
Eyetech is the one in the rebadging-development-motherboards-and-selling-to-end-user business; perhaps they could be interested? AmigaTwo anyone? Wasn't the AmigaTwo supposed to be dual processor (hence the "2")? |

| Posted by Gunnar on 28-Jan-2004 07:18 GMT | The 750 GX is definetly an interesting CPU
but unless its much cheaper than the 7447
I see no reason for Genesi to go for it.
The 750Gx and 7447 used in the Peg II have comparable speed.
The 750Gx has a bigger cache but the G4 has an advanced architecture and altivec.
The 750GX would be interesting if it were available at a higher clockrate.
Just my 2 cents

About IBM 750GX vs MPC7447, I would prefer the 750GX. Indeed, it should be faster (1.1Ghz, and 1Mo of L2) and also less noisy as it only dissips 9W.
Well, that's only my mind :-).

I think it's going to be interesting to see in what way (if any) MorphOS and its applications will use the Altivitec. Wasn't there some rumour of Altivitec support in MorphOS 1.5?
If the Altivitec will be unused (or if it's usage won't offer any big advantages), then there is no reason to use the G4 IMO, and I too would rather prefer this IBM 750GX at 1.1GHz with 200Mhz bus, and *without a fan*!

The original IBM-Clone was made by Compaq "COMPAtible-Quality", it was an original design using a reverse engineered BIOS and MS-DOS instead of PC-DOS (same thing, different name).
I somehow doubt IBM gave out their board designs... |

Where's all the people claiming that dual G3 is impossible?
Dang, when proof comes out, they're not around. Oh well, cannot win em all :-)
(reference: I've been saying single or dual G3 or G4 about the CPU cards for the AmigaOne since day one, and certain people used to pop up _every_ time I said it and claim that dual G3 boards is impossible. The truth is that it's never been impossible, just not very practical with the pre-750FX implementations of bus snooping and cache coherency. Which is why there never was a dual G3 Mac. The problem is that I was never able to reach out to these people, some people just do not want to learn anything new :-) ) |

The G4 is more than a G3 plus altivec.
For example an 7445@600mhz is much faster
then a 750cxe@600mhz even without using altivec.
On the other hand the 750Gx has plenty cache
and its not a 'stock' G3 anymore.
I think its really hard to see which CPU is faster.
According to the IBM and the Motorola website both
have the same Dhrystone score.
But dhrystone is not the best benchmark anyway. :)
The picture will change a lot as soon as altivec is used.
>also less noisy as it only dissips 9W.
If you want to pay a little more you can get
a low voltage 7447 which only needs 7W.
If you want a little more speed then
there are 7447s which run 1.3 ~ 1.4 Ghz.
I think that the 7447 is a good choice for the Peg II.
As soon as IBM brings out the next G3 (750Vx with altivec)
at higher clockrate >1.4 Ghz then I would consider them again.
Cheers

The point is this.
If we take a little example from the Apple world (where money and programmers invested on MacOs X is 10000 times bigger than anty amiga related toy), we can see that only after 3 years from the ALtivec born, there are a decent set of applications that use it.
The prob is that Altivec support must be added by developer and also good coding ambient like Metrowerks doesn't give a good support for Altivec (aka, no automatically optimized code that encrease the speed automatically, and this is, of course, logical due the particular vectorial functions that Altivec CRUNCH).
It could be possible that one day we will see a rudimental OS support for Altivec (in MUI, MagicMEnu, Ambient, Cgxvideo library, 3d APIs, OS libraries ...) but it will happen slow.
The 750GX and the Discovery3 chipset migration we'll be good for 3 easy poit:
1) Overall speed encrease: without counting on altivec use, the GX is faster that actually used G4, thx to the bigger cache and the 200mhz bus.
2) silence please: the machine we'll be completly silent thx to the low low watt consumption (the heat exspected for the 1.2Ghz model is 50°C without any dissipator)
3) the price: 750GX will be 30% cheaper than 7447 due less transistor use (No altivec, no Multiprocess subsys)
Sure, if someone in the Mos team can answer me that "We will add full Altivec support in few months" (and for full I consider DIRECT use in OS primitives of Altivec functions if the Os detects a CPU with an Altivec unit) the use of 750 is not so acceptable.
Anyway go out and ask to Mac people how many software use Altivec unit and when it come out! :D |

I hope to not see this comment banned, Chris.
Amon_re, due the particular function that Altivec engine can accelerate, an hand optamization is required, at last in the compiler directive for POINTED out routines.
Also under X86 atchitecture there are so many MMX, SSE SSE2 3dnow etc compilers optimization, but go out and ask to game developer how great is the speed encrease thx to the compiler optimization.
Anyway, if you think that Altivec specific code is so easy to add, go out in the real world and see what is the reality in Aplle market (for example).
I tought you was a developer: my error. |

Try with CPU centric applications such as media encoding, software non-liner video editing and software 3D ray tracers. Don’t forget that most modern games have DX8 and DX9's shaders optimizations issues e.g. NV code path VS ATI code path. |

The funny part is that for someone you need simply a recompile to obtain a optimized version of a program that use magically Vector Cpu Units, Gfx card shaders feature etc.
I'm asking myself what is the skill level of those ppl. |
