PC World compares the newest processors from AMD and Intel for high-end notebook computers and two computers that sport the new chips. The short version: the Intel chip is faster, has some nifty new features and is very expensive. The AMD is a solid performer at a more affordable price. Both chips suck battery power, though. Read the PC World article for more info.
Actually the Intel chip isn’t faster it was the video as I recall that was lame on the AMD laptop. The AMD chip is a lot better than that Intel chip.
Oh, really? check the Tom’s Hardware article, it says it differently. The new PIII for laptops, called Tualatin-S (with 512 kb interal cache) is faster than Athlon, even at 10% less clock speed. Do your math before you post. I like AMD too, but this is no reason for blindly written posts or comments.
It’s faster in some respects yes. Still the athlon is better in some ways. For the 256K version of the tualatin (which I know there is one) the athlon wins all the tests that I saw. I don’t remember the website it was at. It was a month or so ago I believe. I know they are talking about the 512K one. I’d still argue that the AMD based systems have crap for video compared to the intel ones. All that aside, I’d like to point your attention to something else. Check out the article on the heat dissipation at toms hardware. That’s a laugh. I can say i’m dissapointed in AMD because of the results. I was very very impressed with the way the P4 handled it. That’s the first thing about the P4 that I found that I like. I recommend taking a look at that if you haven’t already.
Too bad intel screwed themselves with the Tualatin and the P4. Makes you wonder sometimes what they were thinking.
>Too bad intel screwed themselves with the Tualatin and the P4.
I do not understand what you mean… P4 is the fastest *desktop* processor on Earth (because there is always Xeon and Itanium for the server market) and the 512 KB Tualatin PIII smokes the previous versions of itself and AMD/Cyrix/Transmeta. The Tualatin is mostly for the laptops, according to Intel’s plans, and P4 for the desktop/workstation systems. I can’t see any screw up over there. Everything is according to plan.
I see some people here are smoking crack the battle between AMD and INTEL there are a hell of a lot of processors out there not just INTEL and AMD most of the are RISK that can kick the S$%t out of ya INTEL anyday wont support no windows but who gives a rats ass about them. and why in the hell does INTEL have to come out with microscopes that must be a sign there going down.

What?! I think not. clock for clock the P4 is obliterated by the Athlon and the P3 beats it too. The P4 just caught up in performance to the Athlon with the release of the 2Ghz and maybe the 1.9 Ghz chip. Even then the chip still gets beaten in some tests. And with October 9th coming along to the release of new chips I don’t think that will last much longer. Also other new chips coming this october.
As for the screw up- I meant performance wise. I realize that their plan was to have tualatin as mobile only. But my point was that the P3 performs better than the P4.
As for the microscopes… lol. I’ve seen those. That was funny.
A *very* good source of information for industry-standard benchmarks is http://www.spec.org“>SPEC here” rel=”nofollow”>http://www.spec.org/osg/cpu2000/results/cpu2000.html”>here</….
A quick summary (CINT2000 / CFP2000)
AMD Athlon : 554 / 458
Compaq Alpha : 621 / 777
HP HP/PA : 604 / 581
IBM POWER : 316 / 409
IBM RS64 : 439 / 376
Intel P3 : 464 / 335
Intel P4 : 656 / 714
Intel Itanium : 342 / 701
MIPS R14000 : 427 / 463
Sun Sparc : 466 / 410
In a nutshell, Intel’s and AMD’s CPUs aren’t kicked by their competition, by far. The Pentium 4 is actually ahead of the pack, and the Itanium looks promising.
“clock-for-clock” comparisons are meaningless. CPUs aren’t designed the same, and a CPU with a 7-stage pipeline just can’t be clocked as quickly as a well-designed 20-stage CPU. If Compaq, AMD, Sun or SGI could clock their CPUs at 2GHz, they sure would do it, and they would kick the P4 for sure. The reason why they don’t do it is that they just can’t do that with the current manufacturing processes.
“the P3 performs better than the P4”. Well, as far as I know, this is only true for legacy code, which was compiled for older CPUs. When compiling code specifically for each CPU (which is extremely important when trying to measure the real raw speed of a CPU), the P4 performs better than the P3, and this is even true if you limit yourself to the slowest P4 1300.

I don’t think that clock for clocks are completely meaningless. Between different architecures I would agree. And about the pipelines, that is definatly true. That’s why the G4 has a hard time with scaling up. It started at 4 I believe and now it’s at 7 stage pipeline. The G5 as far as I know will have a 10. As for a 20 stage pipeline cpu this does allow it to scale a lot higher than other cpu’s in terms of mhz. But, also the longer the pipeline the less efficiant it CAN be. Branch predictions, etc will actually slow things down and less gets done. This is the one problem with a huge pipeline.
Ya, spec is good source but, for real world performance with the P4 I don’t see those numbers showing up. On all the tests I’ve seen it just doesn’t do as well as the athlon on almost all tests. Even with some of the apps that are optimized for the SSE2 enhancements and such. Not to say it’s worthless crap though. It’s definatly an improvement in some areas. But, this is what I mean when I say the 2 or 1.9 p4’s do a little better or as good. There was a test between a 1.2 AthlonMP and a 2 P4 and the results were interesting. The 1.2 MP actually kept up on many things and surpassed the p4 on others. And for the life of me I can’t remember the website and I apologize for that. it might have been vanshardware but, I don’t think so. I’ll see if I can find it. We’ll wait and see how the 1.5Ghz Palimino stacks up here real soon though.
I am really interested to see how the clawhammer and sledgehammer will stack up against other cpu’s. But, we have to wait a while for that.
Also, isn’t there supposed to be an enhanced Itanium soon?
