Intel Pentium D 805 - Dual Core on a Budget

Overall Performance using Winstone 2004
Business Winstone and business applications in general have hardly been a strong point of Intel's NetBurst architecture. The Pentium D 805, along with its brethren, fall to the bottom of the chart. The 805 actually only loses about 4% of the performance of the Pentium D 820, but if single task office applications are all you'll be using you are much better off with the single core Athlon 64 3000+. Even with light multitasking thrown in (as the Business Winstone suite tests), you're still better off with the Athlon 64. You will however lose some of the increase in responsiveness that a dual core CPU will afford you, as dual core CPUs can help mask much of the impact of poor scheduling by Windows when multitasking.
The picture changes a bit when you toss some 3D rendering and more multimedia centric applications into the mix. Now the Pentium D 805 offers better performance than the Athlon 64 3000+, while giving you the more tangible but not easily quantifiable benefits of a dual core CPU.
As the tasks become more intense, the higher clock and faster FSB of the Pentium D 820 become more important; here the Pentium D 820 holds close to a 6% advantage over the 805. Of course at the top of the charts are the Opteron 165 and Athlon 64 X2 3800+, but at more than twice the price of the Pentium D 805 you would expect no less.

amazing how a dualcore opteron @ the same speeds as a non dual core can have a 30fps increase in quake4! :0 (aside from the extra 1mb cache) hope that's a sign of things to come.Sunrise089 - Friday, April 7, 2006 - link
Coming after the Black and White article, it's easy to see the high and low in AT writing. This artcle was fantastic, especially page 2, where Anand comments on all the possible chips in the low-middle marketplace. It's nice to see my Opteron 144 still able to win a benchmark. How important this info will be with Conroe around the corner is anyone's guess, but it's nice to see all the information put out there so effectively.Now if you will, write up an overclocking story on the Opteron 144, X2 3800+, Pentium D 805, and Pentium 4 3.2ghz.

And power use for the overclocked 805 is a must :Dthere goes the idea of having a small, silent, somewhat high performance computer with an 805 :(...

Why wasn't the chip overclocked? They supposedly have very good headroom.JarredWalton - Friday, April 7, 2006 - link
Read the last page. That article is in the works.Viditor - Friday, April 7, 2006 - link
As this is the low end, could you guys throw in an overclocked Sempron as well?Just askin...:)

Agree on the Sempron. Also wondering about the new Celeron 355 at 3.33GHz as the poor 351 gets left behind in all those graphs (though it is cheaper - I almost want the $ figure written on the graphs so I can tell if it's a fair competition or not).I wonder why Intel is making no 512KB L2 cache chips?

Why?This thing would mop the floor with a Sempron.
Viditor - Friday, April 7, 2006 - link
Never let the facts get in the way of a good story, eh? :)
Seriously guys, since Semprons are in this same and slightly lower price range, it would be of great benefit to see a comparison so that we can make some buying decisions.
Cheers!

Actually Sempron 3100+ has about the same performance as A64 3000+.even 2800+ would be faster than 805 in singlethread scenario.
Not saying 805 is bad (actually it is now the best value for money).
Jus your comment is OFF.
