nForce 590 SLI Intel Edition: NVIDIA prepares an Intel 975X Killer

Audio Encoding Performance
Our last audio test (and we are sure our ears and those of the neighbors were ecstatic about this), utilizes Nero Digital Audio to extract all 16 tracks and convert them into an MP4 format. We changed the default quality settings to transcoder-ultra, variable bit rate, encoder quality to high, and the AAC profile to LC. We were determined to give both our platforms a workout with this test.
These results have us scratching our heads as this test is equally demanding of the CPU and storage system, but the Intel 975X chipset completes the task up to 7 seconds quicker in each of our benchmark runs. Even the creation of an iPEAK trace file generated the same results during playback. We did note that the hard drive access was consistent on the Intel system while the NVIDIA board had several throughput peaks but just as many lows that resulted in the slower times. The difference is only 2%, but it's still interesting given that the NVIDIA board seems to perform slightly better in some of the other storage-related testing.
File Compression Performance
In order to save space on our hard drives and ensure we had another CPU crunching utility, we will be reporting our file compression results with the latest beta version of WinRAR that fully supports multi-treaded operations and should be of particular interest for those users with dual core or multi-processor systems. Our series of file compression tests utilize WinRAR 3.60b5 to compress our test folder that contains 444 files, ten subfolders, and 602MB worth of data. All default settings are utilized in WinRAR along with our hard drive being defragmented before each test.
The results speak for themselves with the NVIDIA based system outperforming the Intel system in the decompression tasks by a significant margin (26% faster), but we see the Intel system finishing in front in the grueling compression test (3% faster). Once again, we ran the test several times with the same results. We noticed on our iPEAK test that the disk activity of the NVIDIA board varied somewhat, but the decompression tests are generally more limited by storage system performance whereas the compression tests stress the memory subsystem more. The board could use some additional BIOS tuning for disk activities and the memory subsystem, and hopefully NVIDIA can manage to get more storage subsystem results like the WinRAR decompression benchmark. For now, the NVIDIA board does well in the short and sequential audio tests and file decompression, while it trails slightly in file compression and certain other audio tests.

The problem is determining whether theres really a problem or the reviewers just need to learn how to use the motherboard and BIOS options properly. Wes, Gary, and most of the rest of the AnandTech crew seem to know how to really get results out of motherboards. I saw an article a few days ago that was an absolute joke when it comes to OCing. They took a 4200+ and were crowing about a 240 MHz HTT bus overclock or something. I don't think they ever even tried the other memory ratios.Anyway, registry corruption? Yeah, I've lost the registry a few times on Intel and AMD systems when pushing the OC a bit too far in the wrong way. Bad memory timings for an OC can be just as harmful as a bad CPU or chipset OC - probably even worse. OC'ing is not really that easy if you don't know what you're doing. Too many people want to just increase everything 25% and then tehy wonder why the system won't POST.
Someone on AT did some OCing articles last year about the topic that really provided some good details, showing 2.6 GHz or so with an X2 3800+ using everything from POS value RAM up through top quality TCCD and CH5 modules. Probably took a hell of a long time to complete all the testing as well! If you want to do a motherboard review right and you want to look at overclocking, you simply can't do that without spending a good month or more with the board. Sometimes a seemingly small change will stabilize what appeared to be a hopeless OC.
Bottom line: if you want SLI (and honestly, for dual GPUs it's far better than CrossFire right now - maybe not in performance, but the ATI CF drivers are still crap!) for Conroe, you'll need an nVidia chipset. Unless they suddenly get with the program and start supporting SLI on any dual X16 slot board? God, wouldn't that be nice? Stupid political bullshit... from nVidia and ATI!

Dammit... I did it again and used an H in brackets... which turns on white text for reasons unknown. Repost so people can read the text without highlighing:--------------

You certainly make good points. However one review of "good" and many, many of "bad" doesn't lead me to think the "good" just knew what they were doing. In fact it's quite the opposite. It leads me to think they didn't dig deep enough.Gary Key - Friday, June 30, 2006 - link
I will take a different path on this one. We were allowed a first look at the board with Conroe back in early May, in fact if we could have stayed an extra day we would have had significant hands-on time with the setup. We were also one of the first sites to receive a board from NVIDIA for the specific purpose of testing the board to provide specific feedback regarding Conroe compatibility and performance. I easily have over 200 hours of test time on this board along with a couple of pages of issues/improvements/suggestions we would like to see before the design goes into production. As far as not digging deep enough, I doubt we would have had this early of an opportunity if it were not for our work (and that of several AT readers) with NVIDIA over the past several months in assisting them and the board suppliers to get their Intel performance up to speed. We are still very disappointed with the FSB overclocking results with the NVIDIA Intel designs but our initial board had no issue running up to 304FSB with an early Conroe sample. I am personally disappointed with the entire FSB issue since last fall as I had a couple of boards that easily did over 320FSB only to see this capability whacked when the product was released.
Yes, the board will use the nF4 SLI SPP for the "Northbridge" but it is now at a C1 stepping after several months of tuning due to the issues found last fall in the first release. Are we disappointed that we will not get the newer C51XE SPP, yes, but the time to develop it along with the switch to a single dual x16 chipset this winter made it impractical for NVIDIA at this time. The good news is the NV590SLI boards should cost around $150 at launch with a feature set that will not be matched by Intel or ATI along with using the new MCP55PXE so drive and network performance is greatly improved from a stability viewpoint.
We did not post the actual memory scores as we are waiting on a new board revision and production level bios before making any final statements on this subject and FSB overclocking. However, even with the 805D the base unbuffered Sandra scores were about 2% better than the i975x. When overclocked, this margin flipped in favor of the Intel board. The margin was even greater during our Conroe testing. I am still concerned with the FSB overclocking capability. I stated this at the end of the article, it is a concern and will remain a concern until we see production level boards. I think it will improve compared to today's products but I doubt we will see anything near what the i975x and now P965 chipsets will be capable of in the high end boards from Asus, DFI, Abit, MSI, and Gigabyte. However, getting over 300FSB is a requirement we have placed on NVIDIA at this time. It will be interesting to see if they can get there now.
We appreciate the comments and please keep them coming. Our final review on the reference board will be available shortly and we should have boards from DFI and Asus around Core 2 Duo launch time. However, we do not expect ATI review samples until sometime in August along with some interesting information about their design choice that will be discussed at that time.

Almost every p$ chipset capable of 10066 FSB since i865 tiems DOES support Conroes. Just crippled Intel 915/925 series do NOT bute even this is caused by intel marketing decision not the capability of chipset design on itself.What is most important is the board/VRM support. Otherwise every not-crippled chipset should work.
