AMD Multi-Core Options


I'm going to AMD architecture. And, can't decide on 2, 3, or 4 cores.

The X2 6000+ is a good deal, but will more cores increase performance significantly. IE, can Linux utilize the extra cores or not?

The price difference on the ones I'm considering is only in the ball park of $20-$80 extra.

I noticed on some of the sites that have performance charts, the later ones only include tri-core and above. Seems that the dual core is becoming out dated.

If there's no increase in system performance that is substantial I won't worry about it.

I haven't yet had the chance to use more than 2 cores for more than a week yet, but the quick little bit I had it, it did have a boost compared to my dual-core. Of course, I was doing a lot of simultaneous encoding, so that's where it really helped. When I wasn't doing that, there wasn't really much of a difference, in terms of responsiveness of KDE. If you're looking for a speed boost on single tasks, there won't be much of a difference. As always, YMMV.

If you have an AM2+ socket, and if the price is ok, then go in for a Phenom or Opteron or Quad-core in that order. For desktops 3-core Phenom will be as good as the 4-core ones. See Phoronix for reviews. Lower end Opterons cost a little less than phenoms and will be useful in heavy computing for e.g

I'm curious what impact the clock rating has on common use, such as Internet access and music/video playback.

The X2 6000+ has a 3.1 GHz clock, whereas the X3's & X4's that I'm considering are around 2.2 GHz. If I were to be using app's that didn't take full advantage of the extra cores, would the higher clock on 2 processors perform better?

Sorry about the plethora of questions, but when I look at the review sites, they give performance ratings on the 3D games on Windows platforms, usually. I'm not really a gamer, just occasionally rip/encode some CD's, and maybe a little video.

When performing single tasks, the clock speed is the most important. Of course, you're not really likely to notice a 10% or maybe even 20% difference in clock speed. However, when you start combining tasks such as internet access and watching a video while ripping a DVD, then the total clock speed starts to be important and triple or quad processors come into their own. In gaming, you'd most likely want the fastest video board with the importance of the single CPU clock speed being second. It would depend on the game whether you need the fastest CPU and whether it will run multi-cores.

I just ordered a Phenom quad kit, and am looking forward to getting it setup. As I'm going from an XP2500+, I get a boost in clock speed as well as 4 times the cores. win win.

Yeah, that makes sense. Since the linux OS supports multiple cores well, multi-tasking should be enhanced with more processors.

I appreciate everyone's help. Think I'll go with the Phenom X3 at minimum. It's only $20 or so extra, and since I do do multiple tasks concurrently it should enhance performance. The AM2+ will also let me get the 1066 RAM, since my motherboard has that requirement for that speed.

Thanks again.

Lied. Same MB, AMD 6000+ X2.

Decided for overall increase, main influence hackability at times, 2 cores, are better than tossing one not readily used into the mix.

Thanks for the input...
