IBM has released some information about the new IBM PowerPC Blade. The text mentions 1.8-2.5GHz PPC 970 cpues and also mentions AltiVec, so I guess that solves the old "what kind of instructions will it support"-issue. But maybe that one has been solved since a long time ago?
This is also discussed at slashdot.

IBM PowerPC Blade : Comment 1 of 12 | ANN.lu |
Posted by tarbos on 28-Feb-2003 02:21 GMT | Indeed the altivec-or-not issue was officially resolved back in December:
http://www-3.ibm.com/chips/products/powerpc/newsletter/dec2002/newproductfocus2.html
The new frequency range of PPC970 either hints at IBM being overly conservative
with their earlier numbers (despite the long pipelines) or they keep the 1.8-2.5
GHz CPUs for themselves and only ship 1.4-1.8 GHz PPC to other parties this year.
:-)
An obstacle for a quick launch of this most interesting processor could be the
availability of a taylored northbridge (if IBM don´t do it themselves for a
broad Linux/desktop campaign) with an adequate RAM bandwidth for 1/2 core
clock FSB (dual channel? DDR2?) and the challenge of a usable stable and optimized GCC version. |

Posted by Atheist2 on 28-Feb-2003 06:34 GMT | You think you're sick and tired of your favourite company and mine, making and unfortunately breaking announcements. I'm sick of moto and IBM announcing stuff that is
1) Unavailable - they've been talking about it for almost a year
2) No set date - or am I wrong
3) TOOOOOO expensive - for sure
AND
4) Unusable!!! - Articia "?" when?
What's THEIR excuse? They're multi-billion dollar companies.
Amiga! Don't point fingers. |

Posted by Denis Troller on 28-Feb-2003 06:40 GMT | In reply to Comment 1 (tarbos): I thought the new PPC were supposed to use the new architecture with a northbridge included on chip ? (don't remember the name of this technology, but it seemed to be the "next great thing" about microprocessors when I read about it, and not only for PPC, but for x86 too).
Well, IIRC, it was about Motorola's G5, not IBM 970, but ... |

IBM PowerPC Blade : Comment 5 of 12 | ANN.lu |
Posted by priest on 28-Feb-2003 07:45 GMT | In reply to Comment 2 (Atheist2): 1) Since October last year, so not "almost a year"...
2) I did not find date, but I remember reading that they aim at 2H 2003.
3) Most likely not more expensive as other high end PPC CPUs.
4) I think it's anyway better than be stuck in G4 generation @ 1.3Ghz forever.
Btw... IBM is now talking also about Power5 and it's multithreading desktop variant...
Will PPC970 have hyperthreading/multithreading? |

Half a year maybe. Do you know how long they talked about AMD Hammer??
Or Merced/IA-64 and it´s still not implemented into desktop PCs.
>2) No set date - or am I wrong
2H 2003 with samples in 2Q 2003 iirc.
>3) TOOOOOO expensive - for sure
Why? Afair IBM manufactured cheapo CPUs before - Cyrix/M2.
PPC970 shouldn´t be so much more expensive to make than e.g. P4.
>AND
>4) Unusable!!! - Articia "?" when?
How will IBM use them? |

No.
Hey that would be something for Shawn, _real_ simultaneous multitasking inside
the CPU and no faked timeslicing method! ;-) |

No, the PPC970 is basically a regular Power4 spinoff with addition of altivec.
AMD Hammer has a memory controller onchip, so does Power5 and Motorola G5 (rumored) and maybe the next G4 with DDR and RapidIO (if there will be one). |

Posted by Anony on 01-Mar-2003 21:58 GMT | Imagine a Bewoulf Cluster of these running Amiga OS v5 on them. Yeah AI is making it though some people are trying to upgrade AROS and PegaOS to work too! |

Posted by phillip on 04-Mar-2003 12:37 GMT | In reply to Comment 8 (Anonymous): Well IBM said it would actually be cheaper than G3 to manufacture due
to its smaller size.
They also hint at a downsized version of their Power5 to be used in Desktop.
What I still haven't seen or heard of is a machine, linux, pegasos or anything else being actually tested with it. |
