Multitasking Performance

We devised a script that would compress our standard test folder consisting of 444 files, ten subfolders, and 602MB worth of data, convert a 137MB High Definition QuickTime movie clip to a 37MB MPEG-4 format, play back the first two chapters of Office Space with PowerDVD, and run our AVG anti-virus program in the background. We stop the script when the file compression and video conversion are complete. This is a very taxing script for the CPU, Memory, and Storage subsystem. We also found it to be a good indicator of system stability during our overclocking testing.

General System Performance - Multitasking

The performance difference basically mirrors our PCMark 2005 tests with the ASUS, MSI, and EVGA boards finishing at the top due to great disk performance although the Intel boards consistently completed the QuickTime Conversion first. The DFI RD600 board scored last although it generated the best overall video playback results. Our differences in 1T and 2T timings in this test were minimal with WinRAR showing the only measurable benefits with our memory timings.

Media Encoding Performance

Our first encoding test is quite easy - we take our original Office Space DVD and use AnyDVD Ripper to copy the full DVD to the hard drive without compression, thus providing an almost exact duplicate of the DVD. We then fire up Nero Recode 2, select our Office Space copy on the hard drive, and perform a shrink operation to allow the entire movie along with extras to fit on a single 4.5GB DVD disc. We leave all options on their defaults except we turn off the advanced analysis option. The scores reported include the full encoding process and are represented in seconds, with lower numbers indicating better performance.

We continue to see a strong performance from the ASUS Plus board with the EVGA 680i LT SLI in our application tests finishing ever so slightly in front. We did not notice any differences in this test between 1T and 2T timings which surprised us as CPU throughput and disk access times are the critical factors affecting test scores. Media and Audio encoding are the few CPU centric tasks that NVIDIA chipsets handle well.

Audio Encoding Performance

While the media encoding prowess of the boards was superb in our initial media encoding testing, we wanted to see how they faired on the audio side. Our audio test suite consists of Exact Audio Copy v095.b4 and LAME 3.98a3. We utilize the INXS Greatest Hits CD that contains 16 tracks totaling 606MB of one time '80s hits. We set up EAC for variable bit rate encoding, burst mode for extraction, use external program for compression, and to start the external compressor upon extraction (EAC will read the next track while LAME is working on the previous track, thus removing a potential bottleneck with the optical drive). We also set the number of active threads to two to ensure both cores are active during testing. The results are presented in seconds for the encoding process, with lower numbers being better.

Audio Encoding Performance - LAME 3.98a3

Our Plextor drive consistently took two minutes and nine seconds to read all sixteen tracks. This means our test systems are only utilizing one core during testing until the midway point of the extraction process where the drive speed begins exceeding the capability of the encoder and requires the use of a second thread.

As in the media encoding section, the more intensive CPU and storage system tests seem to favor the 975X over the P965/NV650i-680i/RD600 when running at the same memory timings. However, we are starting to notice a pattern in the latest NVIDIA releases where this is no longer the case, especially with 1T settings enabled on the NVIDIA chipset boards. This is especially true with the ASUS Plus board as we had a seven second difference between the two settings. We consider any results that differ greater than 5% to be noteworthy and depending upon the application, a difference that can be seen when using the systems on an every day basis.

We have almost completed the retesting all of our NVIDIA boards with 1T settings and will provide these results along with 2T timings in our next article if there are significant differences in performance. While the overall differences are minimal in the grand scheme of things, 1T performance can make a slight difference and is worth using if your RAM and motherboard can manage it.

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 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 utilizes WinRAR 3.62 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.

File Compression Performance - WinRAR 3.62

We had stated in our EVGA 680i LT SLI article, "When you need pure CPU crunching power, the Intel chipsets win hands down." Well, today we have to eat some humble pie as the ASUS implementation of the 650i chipset is now holds the performance lead in this CPU crunching benchmark with 1T timings implemented. In fact we have an almost 6% performance difference in this benchmark between timings and to be quite honest, we thought the board was even faster than the benchmarks indicate.

    this mish-mash of different chipsets probably works fine under windows, because asus will provided a tailored nVidia driver to ensure it works.

    but they have always been rubbish at providing a linux variant of the proprietary systems design.

    can i use the standard release nVidia linux chipset drivers to use this board under linux?

    if the answer is 'no' then this board is garbage.

    This board uses the standard NVIDIA 680i driver set in XP and Vista. I had no issues loading SUSE 10.2 on the board but did not test it extensively with RAID or other options. The ADI audio worked but not as well as the Realtek offerings on other boards.

    but only for you and the other handful of folks in that situation...

    Yes, and no. Because users are fed up with MS/WIndows/Vista, a lot of users are making the plunge into Linux.

    Anyhow, it is the softwares responcability to comply with the hardware, not vice versa(to a point that is, obviously the hardware does need to comply with each specification, IE SATA, IDE, x86, etc.), if Linux is to be taken seriously, the Linux dev teams NEED to write a module for every possible chipset out there . . . if not, then well, you will have what you currently have right now, an OS, that does not support near as many hardware configurations, as Windows does.

    Linux is a fun OS, and great for certain situations, but when you have problems like those caused by udev, and whatever else, you can not help but feel like it is not complete. Granted, the Linux dev teams for each distro, is usually much smaller than the teams that write code for Windows. End results however, tend to make this user feel as though Linux is a toy OS, with lots of work still needed. Ubuntu, is good for some situations, and a cutting edge Distro such as SabayonLinux, is also not without its quirks(but 'feels' very simular to Windows Vista.).

    The end result is: what do *you* expect from a free OS ? Personaly, I like each, for different reasons, but still consider Windows to be the only real serious OS, mainly because of support for many, if not nearly all forms of hardware. Look and feel also are a consideration, but Linux has been closing the gap here, for a long time now.

    Anyhow, that 'handful of users' is growing day by day, and is not really a 'handful' any more.

    I could really use to see one. I don't see the differances between this board and a regualar 680i chipset, aside from the northbridges being different (which you would think would impact total PCI-e lanes but... apparently not..).

    so can you put together a map?

    Check this post, it's a dutch forum, but the first second and third table are english, and those are the ones you need.
