The best AM2 CPU? - Page 2

post #11 of 30
Less nm usually run on less wattage/power and cooler. There may be something else, but I don't know anymore than that...

Yes, nm = nanometer. The Brisbane are a newer line of AMD 64 X2 which use 65 nm technology, meaning they are smaller (so AMD can make more processors from the same silicon wafer) and require less power. The lower power consumption should lead to slightly lower temperatures, assuming the Brisbane are as efficient as the Windsor. The Windsor processors are the slightly older version based on 90 nm technology, and use 89 Watts versus the 65 Watts of the Brisbane.

When it comes to choosing a Brisbane vs a Windsor, it doesn't really matter much (in my opinion). The Windsor usually perform about 5-10% better than the Brisbane and are rumored to overclock better. The only real advantage of the Brisbane appears to be the lower power consumption, but unless you really want to save $0.08 on your electric bill it's not a big deal. The main point of the Brisbane is the smaller size, allowing AMD to make more chips from the same silicon wafer which means they can lower the price of the their chips (since production costs are lowered).

As for your specific situation, where you won't be overclocking, I'd recommend a high end Windsor if you can afford it. The Windsor 6000+ is the fastest, and runs about $220 right now. The Windsor 5600+ is a small step down and costs about $170. I think the 5600+ gives the most bang for the buck. The Brisbane 4800+ runs for about $125, and still handle today's games very well (I have a 4200+ and it runs games just fine). Keep in mind that the cache of the 5600 and 6000 is 1MB, where the 4800 and below have a cache of 0.5MB. If you're on a budget, or your cousin isn't going to be doing heavy gaming, go with the Windsor 3800+ for $70.

Agreed. I am loving my 3800+. If I had to do it again though, I would have gone with a 3600+ for overclocking/value but you aren't going to be doing any of that by the sounds of it.

I totally disagree. It is well known that the brisbanes O.C. much better than the windsor core chips. I actually own one of each and the 5-10% performance difference is also untrue. I O.C.'d my 3600 brisbane to match my x2 4600 and benched both in the same rig. At the same clock speeds the 3600 BRISBANE was actually slightly faster in about half of the benchmarks and almost dead even on the other half.

I did a little more research to see if PR1M3R was correct, and here's what I turned up. Nearly every review comparing overclocked 65nm chips to overclocked 90nm chips agrees that the 65nm chip overclocks better. It would appear that the lower temperatures and voltages associated with the 65nm architecture does in fact give more headroom for a higher overclock (by about 100-200 MHz, which is significant). Unfortunately the only review I found in which the equivalent 90nm chip overclocked better was the first review I read, so sorry for misleading you in that respect. Here's that article, http://www.behardware.com/art/imprimer/649/ it was written when the Brisbane first came out, and the voltages on the Brisbanes were around 1.3-1.35 volts, hence they overclocked about the same as the Windsor (or in this article, slightly worse). They have since lowered the voltage to about 1.25 volts, making them more overclock-friendly. But as you said, you're not overclocking this processor, so the better overclocking potential of the 65nm chip doesn't matter at all to you.

As for PR1M3R's other complaints, I'm afraid he's wrong. The 90nm chip does consistently outperform the 65nm chip at stock settings, although it's by an almost insignificant margin. I didn't follow his logic comparing his overclocked Brisbane to a stock Windsor, but I did find some scientific tests comparing 65nm Brisbane X2 5000+ to 90nm Windsor X2 5000+. At stock settings, the Windsor processor outperforms the Brisbane by 0-5% in most tests, and as high as 14% in select tests. Honestly though, the two are basically neck and neck. Here are my sources, you can read up on the differences if you'd like. The only charts that show the Brisbane as superior to the Windsor are the ones comparing power consumption, or performance/power unit. Obviously the 65 Watt processor will win here. But power aside, the Windsor slightly edges out the Brisbane in performance both in games and encoding.

http://www.anandtech.com/showdoc.aspx?i=2889&p=1

And possibly the most important article to read, as it contains information directly from AMD about why the Brisbane performs slightly worse than the Windsor (higher latencies), go here:

http://www.anandtech.com/showdoc.aspx?i=2893&p=3

In conclusion, since you do not want to overclock, and the because the performance margin between the Windsor and Brisbane is for the most part, insignificant, choose which ever one is cheaper

The Brisbane is just a die shrink of the Windsor's design. But why would you get a Am2 anyway? Am2 uses ddr2 so you would have to get new memory. If you are going to buy memory why not get a Core2? That makes no sense to me. If I upgrade from my current config I will get a 939 so I don't have to get rid of my high dollar memory. The funny thing is the 939 proc's are more expensive than the AM2 So If I upgrade to ddr2 I will be going with the leader which sadly Intel.

I dont know why people can't comprehend the fact that some people just like AMD... is it that difficult? I know Intel has the faster procs out right now, that is not even a debate, as does most likely everyone here.

My reasoning to not get a Core2 is the same reason I will never own an iPod. They are great products, but I don't like the company... GO AMD!

I wish I felt that way, well I do.. I just feel done badly since I paid 400$ for my FX-62 when I could've gotten an E6600 for a hundred bucks cheaper..

Opty's seem to be really good for temps, but x2 3600 brisby is probly you best desktop model processor for OCing.

The 3600 x2 overclocked would be the best! Mine 3600 outperforms a 6000 x2
