- POWER & POWERPC MERGE - MULTICHIP POWERPC 630 UNVEILED BY IBM
-
- (May 27th) Plans for a new high-end member of the PowerPC family were
- slipped out this week during the announcement of IBM's new RS/6000s.
- In what appeared to be off-the-cuff comments, a selection of VPs in
- the RS/6500 division described the PowerPC 630 as a 64-bit follow-on
- to the PowerPC 620.
-
- The chip marks the expected merging of the Power and PowerPC lines.
- Apparently the 630 was originally to be dubbed the POWER3 processor.
- Unlike the existing PowerPC processors, the 630 consists of more than
- one chip. James Thomas, director of the RISC Microprocessor Division,
- told PowerPC News that describing it as a 'multi-chip processor' is a
- misnomer. The core processor itself will sit on one chip, however it
- will have a separate cache memory and controller. The processor
- should deliver performance well in excess of today's POWER2
- processors. As such, the processor is aimed at the highest end of the
- market.
-
- The PowerPC 630 is being developed in a way akin to the original
- PowerPC 601, in that the initial development is coming from IBM
- rather than from IBM Motorola and Apple's joint Somerset lab. An IBM
- spokesperson says the processor will be offered to Motorola to
- manufacture.
-
- It is not clear at the moment how the 630 relates to Somerset's work
- on building a post-620 processor. Our best guess is that a separate
- development is already underway, so we will see the 630 and Something
- Else emerge from Somerset in due course. The main imponderables are
- how fast the PowerPC 630 will run and when it will become available.
- Thomas points to his standard chart which indicates RISC processor
- performance doubling every 12-18 months. Other sources suggest the
- 630 will follow about 12 months after the 620, which is expected to
- be unveiled at the end of this year.
-
- Thomas also suggests that IBM has some new technology under its hat
- that will crank up clock-speeds substantially, despite the fact that
- the memory cache will be on a separate chip. The fastest POWER2
- processors currently run at a paltry 71.5MHz, however Thomas says
- that PowerPC processors currently under development are designed to
- run at 300-400MHz.
