Intel Pentium D 805 - Dual Core on a Budget

Overall Performance using PC WorldBench 5
WorldBench is predominantly a single-threaded benchmark that tests mostly older versions of commonly used software. As such, it ends up being a very real world test of how many still use their PCs today.
With the vast majority of tests being single threaded, the Pentium D 805 can't catch a break, although on average it finds itself within about 3% of the Athlon 64 3000+. While it's still noticeably slower than the Athlon 64 X2 3800+, the performance isn't terrible for its price.

Whilst any new system I build will have 'be quiet, dammit' as one of the core requirements, this processor seems to be good value, if only because it is so cheap for what it is, and that it surely will overclock by 25% to catch up with the 3800+ in performance (although the 3800+ can overclock to leave it in the dust, heh).Of course here in the UK power prices aren't 10c/kwh except overnight on economy power plans, so the value does start to look quite poor if you're into buying systems to last 3 years.

One article I'm looking forward to, if Anand could is webserver test. A test showing how it performs in server work over a socket 939 or IT looking to upgrade from Dual socket 370 Pentium-III's or Dual Socket A Athlon MP's maybe curious about how this Pentium-D 805 may or may not be an improvement over their previous box being hosted. The TCO is so low, but is the performance there in SQL or other front end entry level work?Asus & Supermicro make many entry level Server boards based on the Socket 775 that are ready to run with a chip like the 805.
Maybe Jarred can answer that? :)

Bought it a couple of weeks ago, bundled with a cheap 'n' nasty motherboard for £125 - bargain!Runs very quickly compared with my old Sempron 2600+, overclocks happily to 3.32GHz (667FSB) on air with no v-core increase. Given the incredibly cheap motherboard and stock cooling, when I upgrade my motherboard and cooling in a few months' time, I won't be surprised if it hits 3.6Ghz without too much hassle...

Likewise; mine arrived last Thursday along with a Gigabyte motherboard from NewEgg. By that evening I had it running stably in Windows XP at a 40% overclock (3.72HGz) with stock (Intel retail box) heatsink/fan and no vCore increase. Idles in the 42C range. Amazing. I never got my Athlon XP more than about 15% on simple air cooling.I don't have any of the bencmarks from this article so I can't say how it compares to these exactly, but it is up in the AMD 64 X2 4400+ neighborhood on the non-3D benches I do have. Only real 3D bench I have is Q3 timedemo, and most sites use something else. FYI I get ~271fps on timedemo1 @1280x1024 with an Ati X700Pro PCIex.

Care to share the motherboard brand? Fry's is bundling this chip with an ECS mobo for $150 and I'm mighty tempted to build yet another PC if it'll be dirt cheap...poohbear - Friday, April 7, 2006 - link
actually there are currently 3 games that provide support for dualcores, Quake 4, COD2, and the newly released Oblivion. it'd be nice to see some tests on Oblivion to see how much it benefits from dual core cpus (especially when doing some of the .ini tweaks for dual cores that reportedly provide a big boost in performance).nordhus - Sunday, April 9, 2006 - link
4 games, City of Heroes/City of Villains also supports dualcores.JarredWalton - Friday, April 7, 2006 - link
Is there some special step to enable SMP support in Oblivion? If there is, I haven't heard about it yet and I'm apparently missing out on vastly improved performance!As it stands, I've been playing a lot of Oblivion, and I'll be damned if it's actually using both cores in anything resembling an efficient manner. Performance of the two cores together never breaks 100% (out of 200%), which is indicative of single-threaded performance. Windows may be executing gaming instructions on both cores, but the game appears to be as single core as Doom 3, Far Cry, BF2, etc.

yep go to the ini file and change these settings:http://www.elderscrolls.com/forums/index.php?showt...">http://www.elderscrolls.com/forums/index.php?showt...
all the increases have mostly been on dual core cpus. cheers.

Nothing like a game that supports dual cores, but only if you know how to properly hacked the INI file. There seem to be quite a few other hidden options for Oblivion in the INI files as well. I haven't had a chance to actually run benchmarks with the SMP hacks enabled, but that will be coming soon enough.
