"Gregory L. Hansen" wrote in message ... It looks like the machine I have (an HP Kayak XAS, you may have seen me mention it already) can be upgraded from a PII 400MHz to dual PIII 600MHz. But the PIII's are substantially more expensive than the PII's, around $70 each compared to $10 each. I guess I'm not that excited about a 50% increase in clock rate, by itself. But is there a great advantage just in going from a PII to a PIII with a comparable clock speed? Would I get substantially more computing for the money? No advantage at all with today's software, save your money towards a P4 or Athlon system. One other alternative if you have a lot of sdram memory already is to go for a 1.4 gig celeron and a motherboard that takes Sdram. Should be able to put a quality system together for under 150 that way. Lane |

The P-III has more multimedia instructions, so it's a win if you're doing multimedia applications (graphics, movies, etc.). -- -- Skylar Thompson ) -- http://os2.dhs.org/~skylar/ |

Hansen) wrote: There's a wide range of prices, so I tried to generalize, and I was looking specifically at PIII 600MHz 512 cache. I was thinking especially of a matched pair I saw for something over $100, although they had 256K cache. The fact that the top speed for this board is 600MHz leads me to think that it will only work with the "Katmai" flavour of P-III not with its successor the "coppermine". The Coppermine was the one where they halved the amount of L2 cache on the basis that they made it full speed at the same time. These chips require a lower core voltage than the Katmai ones and some motherboards don't have voltage regulators that are capable of supplying the correct one. So, if it says top speed is 600MHz they probably mean that you're limited to the older, 512KB cache, P-III's. I didn't realize there was such a difference between a PIII 600MHz 512K cache and a PIII 600MHz 256K cache. Are all PIIIs with 512K Katmais, and all PIIIs with 256K coppermines? Yep. Default core voltage for Katmai is 2.0v and for early coppermine 1.7v. When I asked about the VRM, I was told the part number 0950-2837 was for any PII/PIII up to 600MHz, and they specifically said it's not for "coppermine". I've asked if the machine would support a faster PIII if a different VRM were installed, but haven't gotten an answer yet, and I'm beginning to wonder if I will. I think the motherboard has the 440BX chipset, if that makes a difference, but I know it also matters which motherboard the chipset is sitting on. And maybe a BIOS upgrade, which HP may or may not have, and which I've never done. Some BX boards handle coppermines fine. I have three BXs here running coppermine CPUs. Some boards require a BIOS upgrade to enable the lower vcore/different instuction set/microcode, some boards just can't handle coppermines. The more I learn about this, the more it all gets complicated by little bits of information like what you've just said above. It's all good fun though. I have several clone machines that started life as PII350s that I got cheaply at auction and now are running various CPUs. The best of them is a machine I am running as an internet gateway/file server on our home LAN. It has a coppermine celeron 600 running at 927MHz with just a slight core voltage increase running in a slightly modified 'slocket' with standard heatsink. It benchmarks better than a PIII850. A bit af a waste of a CPU really, the only difference I notice between it and the PII350 it originally had is SETI work units are done in less than 10 hours now when they took 18+ hours with the PII. My main machine is an Athlon XP 2200+ (1800MHz) that does work units in 4 hours. As I said, it's all good fun. -- ~misfit~ --- Outgoing mail is certified Virus Free.

Try doing something in NT while another program is loading, for instance. The mouse pointer jumps around, things get choppy. A dual processor machine might not be faster, but you don't get that sort of business because there's a second processor to handle the GUI while the other handles interrupts. And I actually wouldn't be surprised if the dual 600MHz *is* faster than the single 1.4 GHz if your benchmark involves doing more than one thing at a time. -- "Is that plutonium on your gums?"

Dual machines make good servers and ok single app workstations but they are terrible desktop machines. The vast majority of software is designed for single processors and are virtually worthless on a dual machine and it's getting worse every day as software developers code for the P4 single CPU. To sit there and wait for a program that can't take advantage of the extra CPU doesn't make any sense with today's prices. One thing that should be mentioned is the overhead that a dual system has compared to single CPU which practically negates any advantage. Lane |

So your trying to tell me that dual 600 system is better than a single 1.4
gig system when every benchmark in the world shows a huge gap between the two. You're missing the point. I'm not talking about benchmarks. I'm talking about usability. Have YOU used a dual-CPU desktop? I didn't think so. Now go back home and play with your toys. steve |

And more nonsense Again do you have anything that shows that they are even remotely close in benchmarks even while multitasking. Dual machines make good servers and ok single app workstations but they are terrible desktop machines. Please, tell me how many dual CPU systems you use as desktops. I've got quite a few here. I'll bet you're talking out of your butt. The vast majority of software is designed for single processors and are virtually worthless on a dual machine and it's getting worse every day as software developers code for the P4 single CPU. Hahahahahaha! You don't have a clue how many things are actually vying for CPU time, do you? And you don't have a clue about interrupts, do you? To sit there and wait for a program that can't take advantage of the extra CPU doesn't make any sense with today's prices. You're telling me that when you run X, and you have the X server trying to get CPU time, your app trying to get CPU time, your kernel using CPU time for disk I/O, your kernel using CPU time for network I/O, and quite a few others, that one CPU is going to get left idle? Like I said, you've never used a dual-CPU desktop, have you? Go home and play with your toys. steve |
