According to the current "Info World" , pp 12: "In the wake of more extensive testing of the Intel Corp P6, it has become clear that the processor does not deliver significant performance improvement over the Pentium when running 32-bit applications in Windows 95." The article goes on to describe performance gains of only 15% when using 32-bit apps on 133MHz pentium systems and 133 MHz P6 systems. They further attribute much of the disappointing performance to the fact that there is so much 16-bit code in Win95. Under other OS's, the P6 should probably perform much better, and of course, these results aren't conclusive, but its certainly indicative of a serious problem for Microsoft. I don't think they could possibly sell NT the way they've sold Win95, given the time frame. It appears that the P6 could be in serious trouble (well, it won't be as successful as the 486 or Pentium, which is to say that it will sell well, but not necessarily continue to dominate the market).

It doesn't have to. It merely has to outperform the M1 and K5. The Pentium already won the real battle -- another CPU line (PowerPC) wont have a big chance to grab marketshare for several more years. >The University of Pittsburgh | Dump the RICO Laws Why? -- ---- Windows 95 and NT: IBM's OS choices for IBM hardware, x86 and PowerPC ---- "That's not our primary target.

I thought one of those two Pentium competitors already had some 30% increase per MHz. And they are coming out sooner. What with the divergence in x86-compatible chips, I don't really see the reason why Intel would necessarily design the fastest nth-generation chip. Followups to comp.sys.intel. Andrew

If P6s eventually go to much higher clock rates than the Pentiums and as a result have better overall performance, despite 16-bit inefficiencies, why won't they be successful in the Intel compatible market?

I'm not sure to which battle you refer. Are you talking about the battle between Intel compatible chips or all computer chips. There was never a battle between Intel compatible and anything else on PC compatible systems. If you're talking about the battle between Pentium and other Intel compatible chips, it hasn't even won that. There are still more 486 systems out there than there are Pentium systems. If you're talking about the battle between Pentium and all other CPUs, it hasn't won that either. The Pentium is only the processor of choice for PC systems. PowerPC has successfully replaced M6K on Macs. All the latest UNIX workstations use RISC chips. That means that PC systems are the only ones left using CISC technology. If you were to recommend to SGI that they use any Intel chip, they would just laugh in your face. >---- Windows 95 and NT: IBM's OS choices for IBM hardware, x86 and PowerPC ---- Win95 is IBM's customer's choice for IBM hardware. It says a lot about a company that they are willing to preload a competitors system on their hardware and even strongly support it to keep their customer's happy. It makes one wonder, "If Microsoft was in the business of selling hardware, would they be as willing to preinstall OS/2 for their customers that wanted it?" NT isn't their OS of choice for the PPC; AIX is. >"That's not our primary target. There are people out there who love > [OS/2 Warp] on the desktop, but our focus is on large enterprise customers." > -- chief executive officer Louis Gerstner (IBM) (July, 1995) Not a bad business decision. He didn't say that the personal desktop is not a target. He just said that it's not their PRIMARY target. They want OS/2 to be as useful to the large enterprise customer as it is to the home user. They don't want to have to offer two separate solutions like Microsoft does. They believe one program can cover both users. Eventually, they want to be able to run an OS/2-like system on everything from palm-tops to super-computers. They don't want people to have to learn a new operating system and buy new applications simply because they've outgrown their present system. They have a much bigger picture in mind. They want to be able to easily transition their PC customers to workstations and their workstation customers to minis and so on. -- ||||||| ||| |||||| |||||| |||||| |||||| || || || || || || || || || || || || |||| ||||||| |||||| |||||| || |||||| || || || || || || || || || || || || |||||| || || |||||| || || |||||| |||||| |||||| Time flies like an arrow.

They are trying to sell systems with a 66MHz 601 as workstations here for the price of a real workstation, like a 133MHz SGI Indy. Or about double the price of a PowerMac 9500. I doubt they could get away with selling an NT system at that sort of pricing. -- Philip Machanick Department of Computer Science University of the Witwatersrand, 2050 Wits, South Africa phone 27(11)716-3309 fax 27(11)339-7965 http://www.cs.wits.ac.za/~philip/ philip@cs.wits.ac.za

It merely has to outperform the M1 and K5. The Pentium : already won the real battle. How come? Many people are still without Pentium and are just about to uppgrade within 1 year. There is still time for Cyrix and AMD to show people their chips performance and little time (not much) to bring those chips to mass market. : -- another CPU line (PowerPC) wont have a big chance to grab marketshare : for several more years. I don't think they are even trying to do so today. I suppose they are waiting the moment when Windows is dead (after Memphis? or maybe before it, who knows who cares) and Win NT is the OS. -- Jani Miettinen t93074@mail.vitech.fi
