Opteron Gaming Benchmarks 39
bishop writes "Ace's Hardware has published some Unreal Tournament 2003 benchmark results on a 1.8 GHz Opteron 244. The Opteron servers out right now don't have AGP, but this issue has been nullified, literally, through the use of the 'null renderer' option in UT2003 to bypass the display output. At 1.8 GHz, the Opteron manages to outpace all previous Athlon models, though it does still fall behind the 3 GHz Pentium 4 by about 8%." Only 8% slower in performance with a 40% slower clock speed. Not too shabby.

Athlon versus P4 performance.. (Score:4, Informative)
I think they've manipulated the design so they can deliberately increase the clock rate for marketing reasons, without getting proportionally more performance out. Basically I suppose they've taken the longest paths through the chip and stuck latches all over the place so that the overall cycle time can be reduced, but operations that used to take one clock cycle now may take two. When 1.8 GHz AMDs can nearly match the speed of a 3 GHz P4, I don't think this is an entirely unplausible theory.
On the other hand, maybe the P4 really just is a pig. There was some discussion on usenet a while back about how it takes upward to 2000 clock cycles to enter and exit an interrupt handler on the P4, something which an old 486 could do in ~45 cycle IIRC (and I don't recall exactly, but I think the Athlon today can do an INT/IRET pair in a few hundred cycles). Curious how in hyper-optimizing these chips for the most common cases of execution, performance of these sorts of periphery operations goes all to hell.
That said, I'm really looking forward to having 64-bits on the desktop. =)

Can you post what the total make world time on your machine is? You only mentioned that it was 10 minutes faster.

As much as it'd be a great story if it were true, Intel are not going to deliberately put out a chip that they know can be outclassed so easily.

They realized that if they made a design that allowed them to ramp up the clock speed to profane levels, they would have the best overall performance.
That p4 3GHz is faster then the fasted AMD has to offer. Considering that not too lang ago AMD had the fastest offering for quite a while, I would say the stradegy worked.
There is nothing wrong with designing a chip for ultra high clock sppeds then attaining them. The only problem I had with the p4 was that right when it came out it was s

I don't see that you've said much of anything, especially concerning the original point - CPU instruction pipeline lengths. In fact, most of what you've said has been a reflection of your character.

1 CPU - I want 8-way !! (Score:3, Interesting)
There's plenty of us that would stick another £200 CPU in the box every now and then as the cash came in.
I mean, I've already got more memory than I ever use and too much HD storage, I want CPUs I never use either.
I like my DUAL 1.2 Ghz p3 mb. I put it together for £300 or so and it's done sterling service, surpassing my normal 18 month upgrade timetable and not looking like it's about to be retired any time soon. (until DoomIII & HL2 I guess 8).
I'll be looking to buy a nice 4-8 way Opteron system and populate it as I go along.
I think Intel missed an opportunity crippling their processors to be non SMP. I hope there's an engineering reason why. I can't really think of a good reason why otherwise, surely they don't make *that much* on gambling that I'll buy a expensive Pentium if I can't have a 4 way Celeron set-up.

That is precisely the reason why dual-CPU machines are much more useful as desktops that the pundits would have you believe.
You'll hear over and over that "you won't use the other CPU", or "your apps won't take advantage of it." In reality, dual-CPU desktops are so much more responsive under load that they still feel "quick" much, much longer than their single-CPU counterparts will.
I have a dual Pentium 133. With NT4 on it, it's just as quick and usable as a P3/650 with Win98. CPU-intensive tasks do take longer, but the machine is still so responsive that you really don't notice it.
Here are the reasons: First, you *are* running more than one program at once, even if you don't notice it. On the Windows side, even with one app, you still have at least 30-40 different threads and/or programs running that you're not aware of - logging daemons, mouse daemons, graphics drivers, timers, and the copious other programs that X and/or Windows will launch. Then, if you're doing net or disk access, that's even more there.
The second reason is because of the interrupts. In a dual-CPU machine, one CPU can be getting hammered by interrupts, and you still have another to run other code, such as your GUI.
After having used dual-CPU workstations, I'll never build myself another single-CPU setup again. If that 2xP133 is still a nicely usable machine, I really can't imagine how long my 2xAthlonMP 1800 is going to last!

True to a point. There must be a working/efficient APIC and the OS has to properly manipulate this for both CPUs to service interrupts. While I strongly agree with a 2-way system being leagues better than "faster" single boxes, there are big-time problems with various OSes including Linux where say, putting a GigE card in, then

The situation with the gigE cards isn't entirely the fault of the OS (although the OS certainly isn't blameless). GigE cards simply generate *swamps* of interrupts. However, the nicer gigE cards give you the ability to turn on interrupt coallescing, where the card will queue up several packets before it sends an interrupt.
That does, of course, increase the latency, but unless you're in a clustering environment, you can generally handle a small hit in latency much better than you can handle a swarm
