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.

Many of you are making a huge mistake. You are proposing insane multitasking tests to 'bring these processors to their knees'. This is wrong! Since when do we adjust the review to the product?This is similar to only running benchmarks whose working sets fit completely into the 2mb cache of a new cpu. In other words, when you review a product like this, do NOT suddenly change all your variables, keep them as you always had them. Later on, you can adjust variables (tests), and draw your conclusions accordingly.
Also, I hope people understand that when Anand would have run these test on a dual Xeon 3.2 system, the results would have been virtually the same. You ALREADY KNOW dual cpu systems can be twice as fast as single cpu systems in certain tests, and show no improvement at all in others.
I really appreciate the article in general, but it would have been SO much better when the PICTURE would have been complete. For this, a dual Opteron system and a dual Xeon system should have been included, AND the tests should have a reflected typical user workloads. If for some reason all cpu's would have been dualcore already, -I- still wouldn't be importing PST files while running my games. Again, when reviewing something, it's wrong to adapt the workload to the product. This is why some people now question your integrety, Anand, because quickly reading through the article DOES give the impression Dual-Core is THE thing, while there's so much it is not!
And yes, i do realize you don't have dual Opteron/Xeon rigs at hand, but still, you choose to present this incomplete picture. It was a choice, but not necessarily the correct one ;-)
Regards,
DvD

Anand for game marks I like to see a dvdshrink deep analysis/encode, with grabit downloading 8 threads with plenty more cued, some seti at home, then run farcry and report FPS.:DThat will bring these single procesors to thier knees obviously but I want to see if DC is really worth it since that's the type of choices I'm forced to choose between.

As I am not a regular reader nor familiar with the benchmarks used in this article, I am rather disappointed that the scales on the graphs in this article do not indicate what is being measured nor whether "higher is better" or "lower is better".Calin - Wednesday, April 6, 2005 - link
What would be better in games (I think), especially in first person shooter games, would be to compare the lowest frames per second, and not the highest or the averaged frame rate. And I think this would represent an tremendous advantage for multiprocessors/multicoreCalin - Wednesday, April 6, 2005 - link
"Nice article, as always. I wonder how memory bandwidth increases/decreases will effect the performance of the already bandwidth hungry intel processors."The Intel processors are no longer bandwidth hungry, as the move to the 1066FSB showed. However, throw a second processor into the mix, and things might change

The Register has a small review on it, and compare it against a dual Xeon righttp://www.theregister.co.uk/2005/04/05/review_int...

Great article - loved the multitasking benchmarks.Here's what I have running all the time:
WinAmp 5
Outlook 2003
Firefox 1.02
ICQQ2003Pro
Norton A/V2005
drivers for audio & video :)
How is my performance affected by multiple Word, Excel, Pshop CS windows? Can I game with them open or do I still need to shut everything down like on my current system? Could I encode a DVD and play a game? Play a DVD off one drive and encode off another?
As mentioned some of what I want to know is can I do things that currently require me to really run two boxes? I recently moved Azareus (torrent client) and all of my DVD encoding & burning to a second rig.

No games tested at all? Since when does this happen? Intel doesn't want dual core to look bad so Anandtech doesn't bench ANY games at all.Come on guys, judging by the article below on the Inquirer I'm not the only one who is suspicious.

Why did you exclude dual CPU (Opteron/Xeon) systems from your comparisons?I recommend that you guys at Anandtech read this:

Well said! ;-)

What about the new extreme edition and I think WinXP only supports a maximum of two cpus? Im not keen to goto 2003 Server. What are Microsoft going to do - patch XP to support 4 cpus?
