Thanks for Remoster for providing the link, give him the rep+ instead of me.

This article test the Pentium D 920 and 955XE against the AMD 3800+ and FX60 in realistic aircooling test. All test go through 24 hour stability test.

Results:

PD 920 4.07Ghz
X2 3800+ 2.56Ghz

PD 955XE 4.36Ghz
FX 60 2.90Ghz

Conclusion:

SUMMARY AND FINAL WORDS
The move to 65nm production technology is all good news for Intel. “Presler” and “Cedar Mill” were immediately retailing after the launch announcement. This is indicating that high-yielding dies in large quantity were available right from production start - something which is not always a given, considering how many “paper” launches we have seen from both Intel and AMD in recent years. Performance is up, and heat slightly reduced. Commercially the move to 65nm is beneficial for Intel as more dies can be produced from one wafer. Presler’s high overclocking potential indicates that 65nm technology will allow Intel to ramp up core frequency even further, be it for the existing 9xx series or later for “Conroe”. Unlike the move from 130nm to 90 nm 2 years ago, this time Intel got it right.

On the other hand: Despite all improvements the Pentium D cannot beat the dual core competition from AMD. Intel could narrow the gap, but for the time being AMD’s FX-60 remains the fastest dual core desktop processor. AMD will introduce a new platform with DDR2 support and a new socket in June 2006. The M2 platform will make the current Toledo based FX-60 somewhat obsolete, as it cannot run on the upcoming, faster motherboards. It’s questionable that someone will spend more than 1,000 US$ or 1,500 AUS$ for a processor he cannot run on a soon to be released faster platform. Not less important for the FX-60 and 955 XE target group of PC “enthusiasts” is that the “Toledo” based FX-60 core seems to be largely maxed out. The 955EE has far higher overclocking potential. At the maximum stable frequency of 4.360 GHz we achieved with air-cooling, it was besting a FX-60 at 2.90 GHz in most benchmarks. For dual core entry-level products we see the situation like this: The X2 3800+ runs faster in gaming than a Pentium D 920. In applications both processors run neck-to-neck with a slight advantage for the 3800+. On the other hand a Pentium D 920 is between 15% and 20% cheaper and overclocks clearly better: We achieved with air-cooling a 45% frequency increase and believe that 40% (or around 3900 MHz) are achievable with almost every air-cooled 920. Overclocked to its maximum stable frequency we found the 920 outrunning a maxed out X2 3800+ in almost all benchmarks.

To sum it up: The general battle order between Intel and AMD has not changed with the introduction of the 9xx series, but Intel’s single and dual core desktop products have improved their relative position quite a lot to their advantage.

My conclusion: On air you can OC the 920 or 3800+ to match the OCed FX60 and 955XE for 1/4 the price.


My intention from this thread is to start a "conversation."

I concur with the article, a cheaper Pentium D 920 that overclocks well is the better choice provided you know what you're doing. Though if you're a newbie, then the X2 3800+ is probably still the best entry level dual core CPU.

How do you know there will be price cuts? And by how much?

What are you saying? the FX-60 beats the OC'd 920 on stock! How can the 920 be better than the fx-60 or 955XE?

Look at the results. At the maximum OC on air, the difference between the 920 and the FX60 is slim to none. Look at the results, only anout 10FPS difference between 920 and FX60... That no big deal for $900.

but that $900 gets you a better OCing fx60/955XE...
But, then again, neither are good ideas as of now...
Especially the fx-60, as it may be the last of the s939s...

You don't understand... A OCed 920 compares with a OCed FX60 and 955XE....

and the 3800+ compares very good as well...
But, I see what you are trying to say. but, I believe that the 955xe was limited...
