I was doing a little research and came across this article about the new 939 socket CPUs.

On the last page is the following statement:

Pricing aside, AMD looks to be producing some of the best performance CPUs we have ever seen. The only hole I can really shoot in their armor is the lack of a HyperThreading-type feature. Now depending on how you use your computer, this may or may not impact your experience. When multitasking, the Pentium4 simply feels smoother to use. You get a seamless experience. Now this is not say that you never feel a lag here or there on a 3.4GHz Pentium4 desktop, but I will assure you there are not many of them. As of writing this, I have 15 windows open on 3 monitors running 8 different applications. If I wanted to, I could also encode a ripped DVD to DivX while I work and never be aware of it for the most part. My experience is that cannot be done on AMD's CPUs.

I was thinking of upgrading from a 2.8C to a 3500+ but after reading this I am somewhat hesitant. Comments?
 
going from my 2.6c p4 o/c at 3.2 to my a64 3400+ clawhammer. i really see no differences in multitasking that i did on my p4. i can burn 2 cds at teh same time running seti surf the internet and listen to music and get no slow downs.
 
It's not as bad as he makes it out to be, but it's not going to hurt anyone's feelings if you stuck with your 2.8C. When AMD and Intel's dual-core chips make it to the desktop, there will be no difference between the CPUs, more or less.
 
I heard [BB] Rick James saying that he liked his OCed P4 better than his OCed A64 because of the slower multitasking, so there must be some truth to this. I'm positive that it isn't that bad, but by the looks of your sig, you may notice a difference :-/
 
I would think that if you constantly do a lot of CPU intensive stuff while trying to do other stuff, the P4 might be a better choice. But if your other "cpu intensive stuff" is nothing more than winamp, internet explorer and a few chat programs, thats not cpu intensive LOL
 
I compare it this way Intel is a Strong man with upper body strength it can hold more of a load then the weaker man but the weaker man was more of a runner in his life so he is faster and can carry more data back and forth quicker.


Strong man (intel)

Stronger Runner (AMD)


So AMD is faster to the clock but Intel can carry more of a load.

I hope that came out what I was trying to say...

im pretty sure it didnot

Ive never tried HT, but I have had SMP systems before.
From what I understand HT is a hack, SMP is much nicer.

However, with very powerful CPU's, I dont notice any slowdown using multiple apps.
At this point in time, I most certainly would not choose an Intel HT enabled chip over an equivilant AMD....I would choose HT over not having HT though.
 
I have a 3500+ that i upgraded to from a 3.0c i gave to my dad and i do notice the difference i have always had 1gb of ram but there is some slowdown. ON my intel i could do all kinds of things at once and have music playing in the background now with the 3500+ if i do the same things i used to my music skips and glitches and there is lag in other programs im using. The 3500+ is a great cpu but if you are an avid multitasker you might want to look at intel.
 
Aw, stop whining. I can listen to music and burn cds on my 466 Celeron FFS. All while writing this reply.

If your music is skipping, you have something else messed up - I've got a XP1500+ that I use the fuck out of and the music never skips.
 
I run Winxp and i run multiple apps all the time... I get slowdowns sometimes but it's never the fault of the cpu... Sometimes my virtual memory gets to monstrous sizes and my hard drives becomeon the bottleneck. I run several high ram usage programs at the same time.

For you guys, I'd check up on your spyware and your task manager to see how well your ram is doing. Nowadays with cpu's so fucking fast I can run several videos using different programs while browsing and my cpu will still not reach over 70% utilization... forget mp3's. They use very little processing... just check your task manager when you feel the comp slow down. You may have new background programs that you didnt' know about. If you use IE then you DEFINATELY do.
 
I use winamp and windows media player to play mp3's and I have never had them skip on me when running anything on my rig. On my old T-Bird It used to happen with a couple of games but this thing has a whole lot more horsepower.

As far as switching between programs, there shouldnt be a delay unless you run out of ram and its grabbing stuff out of the virtual memory.
 
Thanks for the replies. I will stick with my 2.8C right now, maybe upgrade to a 3.4C later or even a 3.4 Prescott if I get the new P series shuttle.
 
HyperThreading is hacked Multi-Threading for poorly designed or broken processors. But for few very specific optimizations for small fragment processing applications, mostly it is just a technical placebo for dumshit technical experts.

When Processors actually have multiple cores and designed with simultaneous data streams for multiple cores, they will just used Multi-Threading instead of hacked version of fractional core processing having only one single data stream for multiple fractional cores..

I don't think calling it a 'hack' is accurate. It works and it's not just for poorly designed or broken processors. It's not SMP, but it's better then just one chip by itself.

That hack had been used for far longer than Intel invention of "HyperThreading".
 
I dunno what you want to call it but its basically a compensation for the P4's huge pipeline.

With HT it basically makes sure that the pipeline is never empty. Without HT you would have a CPU that has the pipeline empty at certain times and which would lower the performance.

Some programs benefit, others don't and still other are hurt. There was a good article on Ananda that showed how the HT on Xeon's hurt performance in a few programs.

MMmmm dual core goodness...

I can't wait to see AMD's dual core CPU.

No nothing else is messed up same setting as b4 only cpu has changed its fast im not complaining i have it at 3800+ speeds now it just could be a little better when multi tasking. And no its not the overclock its only gotten better since overclocking.
 
ha, well if my compare my intel cpu (p2 266mhz) to my amd cpu (a64 3200+) the amd wins by far in multitasking :D :D :D

btw - even with that 266, my music doesn't skip (onboard audio too). get some new audio drivers, and try increasing the buffer size.
 
I can do 20 things at once in my athlon 2100. However, I like doing 55 things at once, which is why dual opterons will soon be in the mail :D.
 
I enjoy the ignorance of people who blame the processor for completely unrelated bottlenecks.

I won't say this way or that which chip is faster, lest be labelled a !!!!!!. I'll just call the people who blame it on the CPU uninformed.

Sorry. I can burn a DVD (yes, a DVD) browse with 7-10 firefox windows and listen to music while filetransferring at 100mbit on both my AMD and the upstairs Intel box.

How? Properly configured systems.

Yeah... I think they started doing that for the video card forum. Not sure why, since there's a lot nastier things you can call people that get through.
 
Not much positive here.
