Intel Pentium D 805 - Dual Core on a Budget

Overall Performance using SYSMark 2004
In the Office Productivity suite of SYSMark 2004 you see a similar picture of the AMD/Intel rivalry to what we saw in MMCC Winstone, with the Pentium D 805 offering performance slightly faster than that of the single core Athlon 64 3000+ and Opteron 144. The Pentium D 820 really starts to show its worth here, offering an almost 7% performance advantage over the 805.
SYSMark's Internet Content Creation tests are dominated by the Athlon 64 X2 3800+, but the Pentium D 805 also does exceptionally well for its price. Here we see about a 36% increase in performance over the similarly priced Athlon 64 3000+. A major reason for the performance improvement due to dual core/Hyper-Threading in this test is because ICC SYSMark 2004 will actually trigger one of those dreaded appllication stalls when multitasking and switching between two applications. Having a Hyper-Threading enabled or dual core CPU alleviates the problem and lets things move a lot smoother. There are obviously other performance benefits to dual core, but SYSMark actually offers us a way of measuring what is normally a very unquantifiable benefit of dual core CPUs.
The overall picture in SYSMark is pretty good for the Pentium D 805: it shows the processor offering greater performance than its AMD cost-competitor, and about 93% of the performance of the Pentium D 820. Interestingly enough, SYSMark on average shows the Pentium D 805 basically equalling the performance of the single core Pentium 4 631.

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.
