Northwood + 533MHz FSB/PC1066 RDRAM should be quite nifty.
The PC1066 benchmarks are here [aceshardware.com].
According to that chart there, PC1066 RDRAM actually has lower latency than PC133 SDRAM. I don't know how accurate that is, but it says PC1066 RDRAM takes 207 cycles for 128 bytes, and PC133 takes 229 cycles (PC800 took 270)?
Maybe I'm reading that wrong or don't know some specifics about RDRAM architecture, but that sounds nifty...

For instance, I remember when I was an undergraduate, my stock Macintosh IIci would take three days to complete a series of calculations I was working on for a stroke study. Bumping up the performance just a bit by mild overclocking cut about 7 hours off of that calculation. I ran this machine overclocked by about 15% for almost five years after as an image capture/file serving machine before finally retiring it to a friends son. That kid used it for another two years before giving it to his sister who finally upgraded a couple of years ago. Last I heard it was still running in overclocked form as a web camera server in a biology lab.

You won't save money by spending days to get the wrong answer
Only way is if you can certify and test the overclocked chips yourself thoroughly, however that would mean spending more money AND time. And when it comes to time, by the time you're done with those thorough tests, a faster chip may have come out
So it only makes sense in rare cases. Or for overclockers who don't care about correct results.
If 100% correct results don't matter, might as well ask an experienced person to guess

You mean simple iterative number crunching. In this case, it is true. For these tasks the dual 800 Mhz G4 running OSX is quite fast as is a dual P4 or single Athalon. However, when computing problems with significant matematical interdependancies that require more information to be driven through the pipline at once, the dual R12000's of the Octane @ 400 Mhz are damn hard to beat for a workstation.
Apple does not yet have the hardware (or software developers) to make me move completely over, but OSX is sure attractive. Hopefully the G5 will shake some things up.

I agree with your VFM argument, but surely, if you're performing calculations that take hours or days (weather forecasts, biotech, scientific research, nuke simulation), they're likely to be important enough that you'd like to have confidence that they're actually correct, rather than save a few bucks/hours and run an overclocked system, right?

On the contrary. I think most non-IT consumers will care about it. When I walk into a consumer electronics store to buy, say, a stereo, all the components have little tags on them with meaningless quantifications like "frequency response: 20-25000hZ", "power output: 240W". These numbers are all meaningless. They will not have been measured in a meaningful way (most likely the power output is measured across a resistor than the speakers themselves). There is no mention of whether it sounds good qualitatively. Everything in the shop probably sounds terrible, compared to an audiophile hi-fi.
Similarly, your average punter in the shop on a Saturday to buy a computer because he read so much about the internet, or because he thinks he should get one for his kids, is going to look at the first number past the first bullet point on the thing and buy the one with the biggest number. This is why Intels policy of cranking up the number as high as possible with the P4, and not worrying about actually making it go faster, is such a good marketing move.

And it can clock much higher.
It's the new core that matters, not the speed (although Northwood is debuting at 2.2Ghz...)

The CPU is only one contributor to performance (Score:5, Insightful)
Three years later, the only thing I added was some more RAM, with the rest of my workstation being the same. It is still very usable, and I rarely see the need for a more powerful CPU.
In contrast, my former office workstation was a P3-800 with 192 MB RAM (some of which to be "abused" for graphics), an IDE drive and a one-chip-does-everything Intel i810 on the mainboard. SETI was the only thing it could do faster. On pushing the IDE system or the network, sound playback got distorted, and the X server became quite unreactive, it even stalled for a few seconds. A compile run made it impossible to do anything different in parallel, so I would have needed two machines - one for compiling and one for the desktop.
AFAICT especially on Intel systems the trend goes towards integrated one-chip-does-everything systems like i810 and its successors, which can handle everything from graphics to sound to IDE to networking. Of course the Intel people want their customers to come back later, and save some money by using only one chip instead of several ones. Most users will think it's the CPU which is too slow... and buy a new 2 GHz monster with another i8xx-crippled mainboard.

Why is it that every story about ever increasing CPU speeds is met by about 50% postings claiming that such speed isn't necessary unless you "want 500 fps in Quake"? I've seen these sorts of posts since back in the BBS days when the new 486 came out, immediately to be met by 50 posts (usually by people who feel a need to justify whatever they own) claiming that "a 386/33 is more power than anyone needs anyways!". Bah.
There are countless benefits to the increased speed (and of course like always: Once you use a higher speed system for a while suddenly you notice, clear as a sunny day, that yes there IS a very noticable difference, and suddenly that previously adequate machine seems pokey), and if you don't realize what they are then continue using whatever it is you use, but save the "500 fps in Quake" rhetoric (here I am with what would have been a cutting edge machine one year ago and Operation Flashpoint runs with frame rates in the single digits, yet even still it isn't a fraction as complex of a "world" as it could be if more powerful systems were prevalent).

But now, a little rant...
Look at the next and last alpha that will come out, it will SMOKE at a fraction of the speed the P4 will be at the end of the year. That's what I call going out with a bang. It's a shame such a technology got obliterated in part because of Intel's markettign muscle, we're going to be set back for 2 years for them to catch up on this technology and performance (they've got some alpha people in their staff now that will teach them how to do more than overclocking and recycling like putting SMT on chips for example, that will be one great leap, it's in at least one of the northwood flavor I think).
Watch out for the Hammer when it will come out, it still going to beat intel's latest offering mhz per mhz in desktop performance (can't speak too fast about the server side though.)
Look at the PowerPC, as much as I hate apple's hyping to keep their blinded userbase into beleiving that they hold the only computer that should exist on the surface of the planet, the powerPC architechture has proven itself to beat the crap out of Intel mhz to mhz side to side (and no I am not talking about that "hey loading an image in photoshop on the mac is 2x faster than on a PC, but I won't mention that it's totally unrelated to the CPU and the mac is running on a SCSI cheetah while the PC was running a 5400 rpm 5 gig drive", I am talking about rendering on different crossplatform software like premiere, lightwave, maya, etc).
This goes without mentionning SUN or MIPS or any other cpus on the planet that has interresting technologies ASIDE FROM CLOCKSPEED.
So again, Screw the MHZ hype, I am a power user, I love doing 3d rendering, I administer a small renderfarm at work, I love raw power, anything that comes out and had a power factor gets my attention, it's nice to see stuff running fast, but I am not impressed at ALL with the MHZ hype. Especially for the PRICE you have to pay to cover all the media and marketting hype... Intel's Hype tax like I often call it. Also, what you see is the MHZ going skyrocket... How much do you thihnk they had to cut in the design so that it stays that stable at these speeds? why do you think the athlon4 can't run at 2.2ghz? design.. intel had to cut in some places so the cpu could be easily cranked up that much, they had to redesign part of it, and that's why you need SSE2 optimisation and the pipeline for standard FPU is so bad. It's not because Intel doesn't know how to design a FPU, it's because they HAD to cut on it...
My precision 530 workstation that runs dual 1.7ghz P4 for the price I payed, I find a dual AthlonXP or MP 1900+ far more impressive for 1/2 of the price. Heck, you want to be in the cool factor? get a Dell 8100 with DVD/CD-RW Geforce2Go 32megs and 1600x1200 15" LCD screen, now THAT'S a nice little piece of technology. And quake plays soooo smooth on it... I won't waste my personnal money or blast my budget for a chip that can generate small blackholes because of it's so great CLOCKSPEED. Gimme raw speed at a decent price. For the price you'd pay that northwood alone you could probably get 2 athlonXP and it's mainboard that beat the crap out of the P4 for the same price of the cpu alone.
