AMD 690G: Performance Review

Test Setup

The Biostar TA690G AM2 was selected as our AMD 690G platform representative today. This choice does not indicate any perceivable performance differences that we have noticed when comparing it against the MSI K9AGM2 or ASUS M2A-VM boards; rather it was chosen after blindly pulling its name tag out of the lab hat. All three boards will be fully reviewed in our mATX roundup next week. At this time, each one offers basically the same base performance with features and pricing differentiating the boards from each other. The MSI feature list is very streamlined but still offers on-board HDMI output along with a price tag that should be south of $80. The ASUS and Biostar offerings are feature rich with price tags that will be around $85 and up. Performance and more importantly stability is excellent in all three boards.

Our first decision was to decide what chipsets to test against. The natural comparison is the NVIDIA GeForce 6150 chipset that has ruled the AMD IGP market for well over a year now. We selected one of the better overall 6150 boards from a feature viewpoint, which is the ASUS M2NPV-VM. There was not enough time to compare the AMD 690G chipset to the current VIA and SIS AM2 offerings as these new products just arrived and we will look at them in the near future.

Our next decision and one that we typically do not do in our normal motherboard reviews was to test the board against a similar board offering but utilizing a different CPU manufacturer. AMD has been adamant that the combination of the 690G/690V chipset and AM2 processor is meant to provide an overall superior platform experience when compared against the Intel G965/Q965 with a Core 2 Duo processor. Of course, they also mean this when comparing their chipset against the NVIDIA products but at least with every NVIDIA AM2 chipset sold, there is a corresponding AMD processor requirement. In the end we chose the MSI G965MDH for our Intel G965 platform offering.

We selected the AMD Athlon 64 5200+ X2 and the Intel E6300 Core 2 Duo processors as our processor choices as both represent great bargains when comparing price against performance in their respective categories. We also switched to Microsoft Vista Home Premium 32-bit as our operating system of choice for this category. After speaking with several of the larger OEMs who are using this chipset and similar ones, we found out this OS choice will be the one most widely offered to consumers. It was a natural then that we would test on Vista Home Premium and a 2GB memory configuration as we suggest this amount as a minimum for Vista.

Our memory and hard drive choices are a little out of the norm for this category but since we are testing the chipset capabilities we were determined not to have a bottleneck in either area. We will test additional budget DDR2-800 memory from G.Skill and Wintec in our roundup along with comparison testing using an external video card. All other components in our test configurations are identical with the boards being set up in their default configurations except for memory settings being optimized to ensure maximum throughput on each board.

Overclocking, network, audio, and memory performance on individual boards will be covered in our mATX roundup. We will say that overclocking on the 690G platforms is in its infancy at this time as the initial BIOS releases concentrated on compatibility and base performance, not overclocking. We have received a performance oriented BIOS for the Biostar and ASUS boards that should allow overclocking now.

Our choice of software applications to test was based on programs that enjoy widespread use and produce repeatable and consistent results during testing. Microsoft Vista has thrown a monkey wrench into testing as the aggressive nature of the operating system to constantly optimize application loading and retrieval from memory or the storage system presented some interesting obstacles. This along with the lack of driver maturity will continue to present problems in the near future with benchmark selections. Our normal process was to change our power settings to performance, delete the contents of the Prefetch folder, and then reboot after each benchmark run. A lengthy process to be sure but one that resulted in consistency over the course of benchmark testing. All applications were run with administrator privileges.

    BlingBlingArsch of the AnandTech forums linked to some pictures of the board, and there's one of the back panel I/O: http://img256.imageshack.us/img256/5498/board234cx...">http://img256.imageshack.us/img256/5498/board234cx...

    Looks like there's definitely no Firewire... :( :( :(

    What are these manufacturers thinking (or rather not thinking) not including Firewire on this boards? These would be totally complete solutions, especially this Abit with the optical out it has, if they'd only have Firewire on them...

    ...and the expansion is so limited, putting in an add-in Firewire basically kills for TV tuner, capture, etc. additions.

    Man...talk about something that's almost perfect that gets ruined by either a poor design decision or a poor bean counter decision... :(

    "The 6150 performs okay considering the age of its core and we will see the new 6150SE and older 6100 chipset performing a few percent better overall but not enough to catch the 690G."

    How would the 6100 be a few percent better when it is clocked lower?

    The review over at http://www.bit-tech.net/hardware/2007/03/02/amd_69...">Bit-tech.netsays the 690G supports dual-link DVI and confirmed as much by sending 2560x1600 over DVI to the dell 30incher. This review however says "Larger 30" flat panel monitors won't be able to run at native resolution" and the technology overview article says "The digital outputs use TMDS transmitters that run at 165MHz". What's the deal?
  • Gary Key - Wednesday, March 7, 2007 - link

    The 690G supports Dual-Link DVI. We had stated this on page two but not in a separate section. I will reword the 2D paragraph to make this clear. As for the resolution, I am using a Samsung 30" panel and the current Vista drivers limit me to 2048x1536. I have sent a board to Jarred who has the Dell 30" to test on it. AMD still confirms that 2048x1536 is the "current" max resolution although we know the hardware has 2560x1600 capability according to one of our sources.
  • Renoir - Wednesday, March 7, 2007 - link

    Hmmm something's not quite right it seems. Can't see why they were able to send 2560x1600 if you couldn't. Would definitely appreciate Jarred checking it on the dell although I'd be surprised if it was a monitor issue. Who knows without trying. Have asked bit-tech what os they were using to get it to work. An XP vs Vista issue perhaps? The related paragraph in the technology overview article mentions the TMDS's run at 165mhz which I understand is single-link? Have seen the 165mhz listed elsewhere for the 690G so am curious where this info comes from if the chipset is dual-link? Unless I've misunderstood something about "165mhz"?
  • Gary Key - Wednesday, March 7, 2007 - link

    The DVI spec transmits data using the transition minimized differential signaling (TMDS) protocol. The DVI spec calls for each DVI output to have at least one TMDS “link” consisting of three data channels (RGB) and one control channel. The maximum speed at which a single 10-bit TMDS link may operate at is 165MHz, offering 1.65Gbps of bandwidth. In real world terms, this means a single 10-bit TMDS link can drive a display at up to 1920 x 1200 (the actual maximum resolution can vary depending on the panel, spec is 1920x1080). For most displays that’s not a problem, but the 30” Displays have a native resolution of 2560 x 1600, which exceeds the bandwidth a single TMDS link can deliver. So what do you do? Remember that the DVI spec calls for at least one TMDS link, but each DVI port can support up to two TMDS links (the 690G has dual TDMS links), thus doubling the maximum bandwidth and enabling support for a 30" (if driver support is present) display or even some of the new 27" units that can run at 2048x1560.

    Thanks for the reply Gary. That was precisely my understanding of the situation which is why I found the following quote from the technology overview article confusing "The digital outputs each use TMDS transmitters that run at 165MHz." This sentence didn't come across as saying the digital outputs had 2 TMDS "links" but rather just 1 running at 165mhz (hence single-link). Perhaps you could reword it to explain that each link runs at 165mhz but that there are actually 2 links in order to support the higher resolutions afforded by dual-link DVI. Don't mean to be picky just think this part could be a little clearer :-)
    As for the resolution cap at 2048x1536 you guys are experiencing the Bit-Tech guys have confirmed they got 2560x1600 working on XP and suggest your problem is an issue with the current vista drivers.
  • Gary Key - Thursday, March 8, 2007 - link

    I have a new Vista driver as of today.

    Here are the specs -
    DVI - Supports dual link up to 2560x1600.

    HDMI - maximum resolution supported is 1920x1080 (using a HDMI-DVI cable
    you can go up to 1920x1200)

    VGA- Maximum resolution support depends on monitor refresh rates and aspect
    ratios:

    2048x1536 @ 85 Hz in 4:3 format
    2560x1440 @ 75 Hz in 16:9 format
    2728x1536 @ 60 Hz in 16:9 format
    2456x1536 @ 60 Hz in 16:10 format

    Hope that helps.

    That's cleared that up then (was merely a driver issue). Anyhow 2 questions

    1) Both digital outputs support HDCP but are on separate display controllers. Does that mean they have 2 built in cryptoroms (1 for each controller) given that separate cryptoroms are required for each controller/output? If they do have 2 then why only allow HDCP on one output at a time?

    2) In a related point (upcoming mobile version of chipset) what connection do laptops use internally for their screens? The reason I ask is I'm interested in getting a laptop in future which supports both hdcp for the laptop screen but also via an external digital connection to a larger display.

    I know its onboard video and stuff, but a 3D Mark06 score of 313? They should be able to better than that, see who can get it into the 1000's first. Although unlikely, it'd be a nice alternative to buying a video card for a basic computing system.
