Memory Test Configuration
The comparison of AM2 and Core 2 Duo Memory Performance used the exact same components wherever possible. Memory, Hard Drive, Video Card, HSF, and Video Drivers were the same on both test platforms.
The motherboards used for benchmarking differed by necessity, but they are both top-line boards from Asus - the P5W-DH Deluxe for Core 2 Duo and the M2N32-SLI Deluxe for AM2. The latest motherboard drivers from Intel (P5W-DH) and nVidia (M2N32-SLI) were used for testing. The hard drive configurations for each test platform only differed in the drivers required for the test motherboard.
Our Corsair CM2x1024-6400C3 modules were set to the following memory timings on each platform; DDR2-400 - 3-2-2-5, DDR2-533 - 3-2-2-6, DDR2-667 - 3-2-3-7, DDR2-800 - 3-3-3-9, DDR2-1067 - 4-3-4-11, and DDR2-1112 - 5-4-5-14.

Is the latency issue really due to intelligent look-ahead or the vast cache size difference between the two processors? I'd like to see a benchmark comparison between an 2MB cache opeteron and an equally cached/clocked/timed Conroe. That would settle some debate (yea, yea...wishful thinking).It could also help lend some insite to what AMD might do in the short & long term as a response as well.
The author of the review seems to give alot of credit to "look-ahead" but I found this benchmark comparison to be interesting: http://www.hexus.net/content/item.php?item=6256&am...">http://www.hexus.net/content/item.php?item=6256&am...
Opteron doesn't seem to have same problem that the Athlon does in terms of latency performance. Which could be why amd execs seem less than panicky at this point. It would allude to a market war similar to the megahurtz war that led to amd coming out with the model # system...this time it could be intel taking advantage of their capacity by laying the cache size smack down on amd instead of megahurtz.
If it is cache size and not "look-ahead" then amd could (could mind you...but would they? and how many could they?) respond much quicker I'd think. If its new technology or a combo of cache and new tech then amd will be in a much worse position imho.
Whatever the case its great for the consumer(me). Thank goodness for competition. Daddy needs a new pair of cores...and the price just got a whole lot better!

It would indeed be very interesting to see a 2MB L2 1.6GHz Core 2 Duo E6200 compared against 2MB L2 1.6GHz Opteron 160.The shared L2 cache of the Conroe will give it a nice advantage though.

Anyonehave any speculation as to how much the initial Conroe's will cost? We pretty much know that the motherboards will be expensive but what about the CPU's?ChronoReverse - Tuesday, July 25, 2006 - link
The pricing has been out for a while already. They're relatively reasonable considering the performance. Only the Extreme Edition as usual is really expensive (but still not as expensive as I'd have thought).Too bad the motherboards are so expensive. I'm taking a look at that Asrock board, but I doubt it'll have any good overclocking capability.

The less expensive boards for Conroe will fully hit the market near the end of August. ;-) We expect to see ECS, Foxconn, MSI, Epox, and others fully ramped up in a couple of weeks on the value boards. Until then, the Gigabyte DS3 is a really good board for overclocking the E6300/E6400 series and our Biostar and Abit boards continue to improve with each bios release. All three are under $145 now with others joining them shortly if the P965 is interesting to you. The ASRock board actually surprised us, but remember the VCore voltage cannot be adjusted. The $50~$100 market will be very interesting as the 945P, 946PL, and NV570SLI chipsets will dominate this section until the G965 boards start arriving in September if decent intergrated graphics are on your wish list, if not all of the boards will offer good performance for the money. The under $55 market will consist of VIA and SIS chipsets from PC-Chips and ASRock with a few majors like ECS and MSI having boards based on these chipsets.

Everest Scores have been rerun with Version 3.01, which was released on July 16, 2006. Since the scores from the new version can not be compared to older Everest scores, we reran all the Everest benchmarks. 3.01 is said to provide full and complete support for Conroe and Merom. Values are different in that Memory WRITE and READ scores are reported as much higher than past Everest testing. Latency is also reported as closer between AM2 and Core 2 Duo with the 3.01 version of Everest. Charts and commentary have been revised using the new results.jjunos - Tuesday, July 25, 2006 - link
Thanks for the update wes! It always shows the quality of the website when they listen to their community and and willing to rerun all their tests in the sake of being correct! kudos!TonyB - Tuesday, July 25, 2006 - link
is it just me or did AMD just get pwned?bob661 - Tuesday, July 25, 2006 - link
I personally don't care about who owns who. I just want competition so I can get this stuff for cheap. I'm a best bang for the buck guy.goinginstyle - Tuesday, July 25, 2006 - link
Everyone benefits here with the performance improvements Intel has brought to the table and an AM2 3800+ at $150 is just an incredible value. Conroe made it easy for AMD users to upgrade their performance for very little money.
