I was talking more of the fact that some speedos aren't precise about the exact speed they're displaying, at a quick glance at least, so the driver might not be aware of precisely how fast they're going.
There is of course the counterpoint that 5mph is the width of the needle in some cars, methinks tighter regulation on speedometers could be a good idea?
notice in this POV-Ray test, the P4 needs a _1 gigahertz_ clock frequency lead to pull even/ahead (depending on ram type) with the Athlon.. that my man is brute force floating point power in action:)
The 2600+ OTOH, IS barely competitive with the 2.53Ghz P4, the 2800+ has a faster bus though, and that seems to balance things out, with the 2.8Ghz P4 still having an edge when bandwidth is the bottleneck, and the Athlon having an edge when raw computational power is the bottleneck.
1) Xeon 2) Macs won't be shipped with POWER4's in them, they'll _probably_ be shipped with PowerPC 970s (which are effective single core Power4's + VMX)
a single Power4 core (rather than the 4xdual-core die MCM's) uses ~60w, that's hardly 8 times the power draw of a Northwood/.13 Pentium 4

turn off Mozillas Quicklaunch memory resident stuff, then start them both (sequentially).
Phoenix starts as fast as IE does, click *beat* open browser window (and IE is (mostly?) memory resident)
on this AthlonXP @ 1.6Ghz with a gig of ram and a WD1200JB (WinXP SP1), Mozilla OTOH takes like 8 seconds from click to browsable window unless quicklaunch is running.
" But at the same clockspeed, I'm pretty sure the Power4 would kick the ass of this new chip at SPEC benchmarks."
Think is, the GPUL will be simpler (no second core), and manufactured on a smaller process, so it's clockspeed heatroom will likely be a fair bit higher than the POWER4s by my reckoning (whatever that's worth... probably not much:))
The problem with that is, a.18 POWER4 is totally unfeasible for a desktop machine.
in addition, this stripped down POWER4 should clock a LOT higher due to the smaller process, and being a less complex chip. (and it'll use one hell of a lot less power)
It's just like the 604e verses G3 all over again, except the PPC7455's replacement might will be the brute force implementation:)

good luck doing scientific calculations on a Geforce:)

^^^^ that idea has me intrigued, anyone who actually knows more about FPGA's than me (which isn't difficult) want to go into pluses/negs with that concept?
Hmm, that's peculiar, you're about the fifth person in the last month to tell me that they're having problems with an Athlon rig and an Enermax PSU....
QA issues at Enermax perhaps?
And it won't run XP?.. VIA 4-in-1's?... they'll either fix it perfectly or make it crash and burn in a manner you never thought possible. (such "fun" is why I avoid VIA)
the SiS 735 is a perfectly solid little chipset, the problem lies elsewhere.
Either
1) you got a half-D-O-A mainboard in the first place 2) your PSU/ram were subpar 3) the mains power to your house is subpar (this ties to the PSU being subpar)
On the other hand, the most troublesome board I've EVER owned was an Abit SH6 (i815E chipset).
Abit are certainly off my list. (btw, which SiS chipset board was it you had problems with?)

FYI, most modern bioses recognise USB keyboards and can be accessed from them.

Go read some 2800+ benchmarks, those suckers ARE performance competitive with 2.8Ghz P4's, if only we could BUY the damned things.
:)

Who the hell modded that post as offtopic?, how is it offtopic to discuss HARDDISK FAILURE in reply to an article about harddisk warranties...
(this post OTOH, IS offtopic, and should be moderated as such.)
"only 90% of altivecs hundreds of opcodes will be offerred though."
Source?
Altivec is 162 instructions, and the Microprocessor forum brief on the GPUL stated "over 160 instructions"
"Pentium 4s have no multi-cpu board designs..." Really?
Intel seem to think otherwise
And here's a nice quad processor board for them.
1) Xeon
2) Macs won't be shipped with POWER4's in them, they'll _probably_ be shipped with PowerPC 970s (which are effective single core Power4's + VMX)
the "Gekko" chip in the Gamecube is actually a slightly modified PowerPC G3 :)

IMO, applications should look like the host OS or they should go the hell away.
per-application skinning is the scurge of our time! (I think a lot of blame can be leveled directly at WinAMP for this)
Since the first showing of Doom 3 to anyone that doesn't work at iD was on a PowerMac G4 with a Geforce 3, I'd say that they already do.

Doesn't 16-bit addressing work out to 16MB?
(perhaps you meant to say 8-bit ?)
For a small machine to tuck away in the corner to act as a gateway/caching proxy etc for a small lan, it's perfect.
:)
It's no match for a proper rackmount server though
Well, surely you could prioritise it to prevent less performance critical applications getting their hands on it when something important needs it?
I'm fully aware that 3d accelerators do lots of maths..
but without high precision and some way of getting the data OFF the videocard, then it's utterly useless for scientific purposes.
How slow?
and if it were for something like a 20 hour 3d render, would it matter if the initial setup took a while?

Personally I've taken to referring to the current breed of x86 chips as "CRISC"
Complex frontend and all that...

"it has been running win2k for over 4 days now with out a problem"
If it's running without problems, why are you bitching about them being problematic?
(I notice you didn't mention your actual in-system PSU whilst you were reeling off the UPS stuff.. a flaky PSU can cause extreme twitchiness.)
the SiS 735 is a perfectly solid little chipset, the problem lies elsewhere.
