Athlon XP1900+ -- Faster Than A 2GHz P4?
doormat writes "AMD releases their AthlonXP 1900+ Processor today, thats 1.6GHz. And it seems like its enough to topple the P4-2.0GHz, even in Quake 3 Arena!! AMDMB has a review of it." Ian Bell points out an AMD press release on the new processor. I love watching my old Athlon get slower every day ...

Wait 20 seco....SHUTUP!
One thing I've noticed over the last year or so when talking to non-techie friends/family is that many people with relatively little knowledge of IT as a whole are starting to realise that the processor speed, however it's being measured, is far less important than the vendors want them to think.
The end result of Intel and AMDs battle of "my processor's faster than your processor" seems to be that people are saying "I don't care" - as they realise that there 'obsolete' PII is actually perfectly capable of doing all the things they use their PC for and that only graphics people and the hardest of hardcore gamers actually need 1.5 to 2GHz.
Nice editorial work guys.
I saw a review comparing an Athlon 1800 and a 1900.
I didn't see a single thing in there that mentioned the P4 being outperformed or toppled.
Just unsupported speculation.
...they didn't test it on quack3.exe.

Ok, Yet Another Lame/Appropriate Analogy:
Considering the last time a topic such as this compared the Intel's best P4 to AMD's best Athlon.
The Car/Engine analogy was used to no end and many valid points were made, but noboday really put it into a conclusive and easy to understand "package" that the Average Joe User could understand.
Recall, if you will, the movie "The Fast and the Furious" as the analogy of Intel vs AMD saga.
Remember the scene at the end with the race between the souped up Honda and the Toranado?
Intel's P4 is akin to the Honda, as it has a lot of "high-RPM's" and "high-tech" under the hood (i.e. 2.X Ghz and Rambus et al).
The Athlon is like the Toranado(?) and American Muscle car that had the "High Torque" and "lower-tech" that relied on brute force (i.e. 'superior' FPU and Large cache and the blower is similar to DDR-SDRAM in a way).
The end result of the race at the end of the movie was that they (for the most part) tied.
The current Intel/AMD debate is very similar, in that you have all this high RPM/low torque (intel) vs old school High Torque/mid RPM's (AMD).
If it is not on fire, it is a software problem.
Hi.
Large matrix multiplies are in fact used as benchmarks by many sites, and are part of specFP, sysmark, and other benchmark suites, many of which you'll see quoted (though not specifically the mat mult part) in these reviews.
The problem is that matrix multiply only tests your floating point/simd unit and your i/o bandwidth. Not a very comprehensive test, and unless you actually plan to do large matrix multiplies, quite synthetic.
As for your web page serving idea, it's called specweb, and anyone who is catering to or buying in the web server market cares a lot about this benchmark. It is a more comprehensive test than just multiplying matricies, but still only targets certain aspects of the cpu (I/O again, cache size).
Games actually make a good addition to these benchmarks. A modern game engine can tax a cpu a great deal, and will use a mix of integer and floating point applications, plus put pressure on the memory subsystem. If the performance isn't limited by the graphics card, then you can use games quite effectively as CPU benchmarks.
It's funny that you mentioned "real". If you're running sicentific apps that multiply lots of matricies, then matirx multiply is "real". If you're running anandtech.com, web serving is "real". And, if you're a gamer, games are real and the performance you see in them is what is the "real" performance limited.
It almost sounds like you want the "max", as generated through some kind of synthetic test. As in the performance you'd never, ever get in a actual application that you'd want to run once you'd bought the system. Which was how it used to be done, and it sucked, so everyone stopped. Let's not suggest we go back, hm?

AMD Zone gives this summary at the end of its review: "No architectural or marketing changes with this release ... expect the previous CPUs to decline in price ... expect a bit higher performance and power consumption."
Anandtech agrees, saying the chip will not offer any significant extra performance over the 1800+, so early adopters need not sweat too much about being left behind. The site believes that AMD is currently the performance leader on desktop processors.
VIAHardware.com reckons users could be just as well off picking up the 1800+ at 1.53GHz and simply overclocking it to 1.6GHz. Users already owning a high-speed XP chip are better off waiting for the next upgrade on the platform to significantly increase performance.
Tech Report has some extensive benchmarking, putting the 1900+ slightly ahead of Intel's P4 2.0GHz in most of them, while SimHQ.com gets very excited about the new chip.
Amdmb.com also has a piece showing the expected five to six per cent performance increase.
What on earth did you do with your home computer to make the heat sink fall off your graphics card? (Or was it not attached properly to begin with?) I'm sorry, but it looks to me as though Tom's Hardware was pretty desperate to make any sort of anti-AMD point it could (BTW, it was running Intel ads on its site back when the 2 GHz P4 came out)--rather like Car and Driver running an exposé of what happens to your car if you take the fan and radiator off and then go drag racing. Duh...
