Intel Dual Core Performance Preview Part I: First Encounter

The Platform: Intel 955X
AMD's dual core Athlon 64 processors will work in all current Socket-939 motherboards with merely a BIOS update. The same level of compatibility obviously isn't true for Intel's dual core solutions. You'll need a new motherboard to support the Pentium D and Pentium Extreme Edition chips, and thus, Intel shipped us a board based on their soon-to-be released 955X platform.
The platform boasts a dual channel DDR2-667 memory controller, but given that the chips still only support an 800MHz FSB, the added bandwidth of DDR2-667 is useless. Even for bragging rights, running at DDR2-667 doesn't make sense, as the memory that Intel shipped with the system is rated at 5-5-5-15 timings at 667MHz. Wasted bandwidth and higher latency memory is nothing to get excited about in our book. We're not entirely sure what Intel is up to, but they had better plan on increasing the FSB of their chips really soon if they want DDR2-667 (or even 533) to gain any sort of acceptance.
Other than support for dual core, faster DDR2, RAID 5 and 8GB of ECC memory, the 955X doesn't have any features to boast over the current platforms. It does look like Intel may be planning SLI support for the 955X however:
The 955X board that we received had two physical x16 PCIe connectors, but only one of them was electrically a x16 slot.
Despite Intel's warnings not to make any judgments about final performance or stability, both the 955X and the Pentium Extreme Edition were as rock solid during our testing as any product that we've encountered. This was quite possibly the most stable encounter with a pre-release CPU, chipset and drivers that we've ever had. That being said, we really didn't expect Intel to break tradition with a platform of which they weren't 100% sure.

AMD's dualcore will use less power and produce less heat apparently and last I checked an FX-51 (2200) out performs the Intel 3200 in a single core configuration so it will be interesting what a dualcore AMD at 2200 or 2400 will do compared to the Pentium 4 3200 dualcore. AMD is going after the busines market where the money and the desire for dual core will be greatest. Why isn't Intel going for that market? Interesting question.CrazyCurl - Monday, April 4, 2005 - link
good review! cant wait to see more info. I am particularly interested in heat dissapation as well and would be nice to see the new unreal engine that supports multithreading benchmarks but that would be be a ways off id assume.Is the 955X gonna support pressler? is that why it has 1066 fsb and ddr-667?

How about a web developer test I constantly run these programsDragonflycms 9.1.2
Apache 1.3.9
MySql 4.1
PHP 4.0
Photoshop 7.0
Flash MX 2004
Fireworks MX 2004
Dreamweaver MX 2004
Firefox
Hydra IRC
Messenger
Yahoo Messenger
The web server and mysql drastically effect the runing of the multimedia applications. This would be a great multitask test.

#34 You are absolutly right there Anand, to this day I have still not had a single CPU system as responsive as my old dual O/C Celeron 550 machine. I ran it along side a P3/800 for a long time and always much prefered the Celeron box for general day to day tasks, hell my AMD 3500 feels damn fast most of the time but when I try multitask a bit too much it just takes forever to even get menus to pop down. Dual core is definately the way to go for the future, when the apps/games start to catch up with the technology everyone will wonder how they ever did without a multi core/cpu system.stephenbrooks - Monday, April 4, 2005 - link
If it's any help to y'all asking about thermals, [H]ard|OCP says:"Our Intel 840 will have an operating voltage between 1.2V and 1.4V and have a Thermal Power Design of 130W"

thanks Anand... it is the power consumption and power dissipation profiles that I really want to see.Anand Lal Shimpi - Monday, April 4, 2005 - link
oh and power consumption is coming... :)Anand Lal Shimpi - Monday, April 4, 2005 - link
Hans MaulwurfThese usage scenarios were described by AnandTech readers in my recent request for benchmarks, they weren't anything prescribed by any hardware manufacturers.
Ask anyone who has used a dual processor system, things are just smoother. The reason we've never recommended dual processors systems in the past is mostly because of price. In less than 3 months you should be able to, in theory, purchase a dual core processor for as little as $240. Not since the days of the dual Celeron 300A systems has dual processing been that affordable.
Take care,
Anand

The best thing about dual core is that you do not need HT aware OS's anymore. It sucks when you want to run Win2000 with HT and getting slower speeds.Shlong - Monday, April 4, 2005 - link
Instead of trying to take screenshots, maybe you could've used one of those desktop video capture programs to try to get a better visual representation of what you were trying to explain.
