It’s almost like we say this every year, but Computex hasn’t even officially started yet and we already have a lot to talk about.  Everything from the power requirements of next year’s GPUs from ATI and NVIDIA to the excitement surrounding Intel’s Conroe launch is going to be covered in today’s pre-show coverage so we’ll save the long winded introduction and get right to business. 

We will first address some of the overall trends we’ve seen while speaking to many of the Taiwanese manufacturers and then dive into product specific items.  We’ll start with the most shocking news we’ve run into thus far - the power consumption of the next-generation GPUs due out early next year.

DirectX 10 GPUs to Consume up to 300W

ATI and NVIDIA have been briefing power supply manufacturers in Taiwan recently about what to expect for next year’s R600 and G80 GPUs.  Both GPUs will be introduced in late 2006 or early 2007, and while we don’t know the specifications of the new cores we do know that they will be extremely power hungry.  The new GPUs will range in power consumption from 130W up to 300W per card. ATI and NVIDIA won't confirm or deny our findings and we are receiving conflicting information as to the exact specifications of these new GPUs, but the one thing is for sure is that the power requirements are steep.

Power supply makers are being briefed now in order to make sure that the power supplies they are shipping by the end of this year are up to par with the high end GPU requirements for late 2006/early 2007.  You will see both higher wattage PSUs (1000 - 1200W) as well as secondary units specifically for graphics cards.  One configuration we’ve seen is a standard PSU mounted in your case for your motherboard, CPU and drives, running alongside a secondary PSU installed in a 5.25” drive bay.  The secondary PSU would then be used to power your graphics cards. 

OCZ had one such GPU power supply at the show for us to look at. As you can see above, the 300W power supply can fit into a 5.25" drive bay and receives power from a cable passed through to it on the inside of your PC's case.

OCZ is even working on a model that could interface with its Powerstream power supplies, so you would simply plug this PSU into your OCZ PSU without having to run any extra cables through your case.

In order to deal with the increased power consumption of this next-generation of DirectX 10 GPUs apparently manufacturers are considering the possibility of using water cooling to keep noise and heat to a minimum.

As depressing as this news is, there is a small light at the end of the tunnel.  Our sources tell us that after this next generation of GPUs we won’t see an increase in power consumption, rather a decrease for the following generation.  It seems as if in their intense competition with one another, ATI and NVIDIA have let power consumption get out of hand and will begin reeling it back in starting in the second half of next year. 

In the more immediate future, there are some GPUs from ATI that will be making their debut, including the R580+, RV570 and RV560.  The R580+ is a faster version of the current R580, designed to outperform NVIDIA’s GeForce 7900 GTX.  The RV570 is designed to  be an upper mid-range competitor to the 7900GT, possibly carrying the X1700 moniker.  The only information we’ve received about RV570 is that it may be an 80nm GPU with 12-pipes.  The RV560 may end up being the new successor to the X1600 series, but we haven’t received any indication of specifications. 

After the HDMI/HDCP fiasco that both ATI and NVIDIA faced earlier this year, we’re finally seeing video cards equipped with HDMI outputs and full HDCP support.  The HDCP solution of choice appears to be a TMDS transmitter by Silicon Image that has found its way onto almost all of the HDMI equipped video cards we’ve seen. 

While some of the HDMI equipped graphics cards simply use the HDMI output as a glorified DVI connector, other companies have outfitted their designs with a SPDIF header to allow for digital audio passthrough over HDMI as well.  Remember that the HDMI connector can carry both audio and video data, and by outfitting cards with a header for internal audio passthrough (from your soundcard/motherboard to the graphics card) you take advantage of that feature of the HDMI specification.

Alongside HDMI support, passively cooled GPUs are “in” these days as we’ve seen a number of fanless graphics cards since we’ve been here.  The combination of HDMI output and a passive design is a definite winner for the HTPC community, who are most likely to be after a video card equipped with a HDMI output at this point. 

Conroe Motherboards Arrive

    wow, all I can say is wow. I am quite impressed with Gigabyte desktop motherboards. From the pictures it looks like a better design than even what DFI would do. Also the ASUS socket F board looks excellent. Quite impressive since I am used to think that ASUS' server boards are inferior to like supermicro/iwill/tyan. Reply

    Page 18 of the article seems to be mixed up since the Albatron boards are showing up instead of the Asrock. Reply

    Actually consider what AMD is doing at all. Boy times have changed! ;)

    I'm a life long AMD fan too. Short life, but life long.

    Where have you been? It's been like that for quite a few years now. Remember when DDR2 was actually on the market? Who wasn't using DDR2 then?

    Unfortunately due to changes in the VRM requirements for Conroe, no current LGA-775 motherboards will work with the new processor.

    There is a lot of concern about the availability of Conroe, as Intel has only committed to around 25% of its mainstream and high end desktop processor shipments being Conroe by the end of this year. After Dell and HP buy up all the Conroes they will want for their systems, there simply may not be any left for the end user to buy in the channel market. Alternatively, there may end up being some supply in the channel market but at significant markups due to a shortage.
    Interesting. Looks like Conroe's may come at a premium until Intel can increase production.

    I dont get it, what is the point of sending audio to the monitor?
  • Furen - Monday, June 05, 2006 - link

    It's meant to be sent to an HD TV. Monitors can just use DVI for digital signaling. Reply

    And whats the point of that too? Its supposed to go to the reciever not the tv. Reply

    Do you even know why hdmi exist. Most HDTV that have HDMI connects also has audio out.
    YOu connect everything to your tv and send out only singles you need. My guess is you don't have a HDTV.
