Graphics State of the Union

Tom's Hardware has put out a nice recap of where computer graphics have been and where they are headed in the near future. While there are some definite shiny toys being displayed in new product releases and on the test beds, the overall problem of power consumption continues to rear its ugly head demanding attention. From the article: "while all of these things are interesting, exciting and new, the problem remains the same. Getting smaller and faster only makes sense if the design also is less demanding on the wall socket and cooling system. We all want different things when it comes to advancements, but first and foremost we need better power management. The bottom line is simple: graphics makers must take a step back from feature brainstorming until the power issue is resolved."

I am finding more and more games that are simply pleasing to the eye but lack the originality, functionality, and creativeness of older games. These video card makers focus too much on realism and tend to encourage game makers to focus on the like. Let's make cards that are functional, less power hungry, well-rounded (physics), and cooler.

    Today this is irrelevant. If consumers continue to purchase ever more power hungry graphics cards, what is to stop the companies from making them? When the market actually changes and people start considering the power requirements of their cards, then I'll believe this statement about the bottom line. Because right now the only thing I hear from people building or buying new computers about the power requirements is "make sure you get a PFC PSU and get lots of watts", not "make sure you get a low-power GPU". For one thing, some people actually enjoy saying they have a 600+ watt PSU. I can imagine that with current power costs today this trend will continue. Do the math, it's not actually costing a person much more per month to go from 600 to a 1000 watt PSU, especially since most people don't use their GPU to full power most of the time.

    Power requirements take a back seat to overall performance, and will continue to do so until electricity costs are driven up further. It's simple economics. People are willing to pay for the power-hungry cards. And until they're not, power consumption will continue to be less important to the producers than performance. This is analogous to today's vehicles, still being built and shipped with huge fuel sucking engines. For many people, and I'd wager to say enough to sustain the market for years to come, the cost of energy (either liquid or electrical) is still low enough that they aren't going to give up their cherished powers, be they piston driven or transistor.

      Of course this doesn't address the fact that, when needed, and when ramped up, they consume a lot of power. To which I say, yes, we need more power efficient cards.

      This is unique to the mobile sector for now, but of course will eventually find its way into the entire realm of graphics computing.

      Yes, the market will decide the issue -- much like it did the CPU market. Intel didn't drop the PIV lightly, but were forced to do so when the costs of pushing the power envelope were hurting them in the market. They fell behind AMD in performance because the power limitations were slowing the clock speed pushes they needed to keep up. Intel eventually saw the writing on the wall and went with a design where power consumption was a primary consideration.

      Eventually, the market will force GPUs down the same path. Raw performance is still the primary driving force today, but this will change when thermal limits slow the clock speed increases needed to reach the next performance level. When that happens, low power designs will win the day by providing more resources for the same power budget.

      There are also other considerations such as fan noise. Many folks would willing trade raw graphic performance for less noise. This is a critical parameter for an HTPC, but it's also a virtue for standard desktops. Consumers will start demanding refunds if they have to shout to be heard over their blazing new graphics card.

      • The PSU only draws power proprotional to the load on it. The rating is the maximum draw, not the minimum. Two PSUs of equal efficiency but different ratings, supplying the same load, should draw the same amount of power.
      • The ratings are lies anyway. The manufacturers add up the numbers in ways that make NO SENSE AT ALL in order to get the largest numbers they can. They do this because it sells PSUs.

This isn't cutting edge hardware either...it's an Athlon XP 3200+, Radeon X850XT video card, SB Audigy 2 ZS. Basically all of the hardware is pretty much the cutting edge of the last generation, pre-Athlon64, pre-PCI Express. The system started experiencing problems when I swapped the old Duron 750 for the Athlon XP (I was still using a Radeon 9200 then). I had to swap the video card with a Radeon 8500 to get it to run somewhat stable again. At the time, I incorrectly attributed it to the video card, thinking it may have been bad (it was given to me when my roommate upgraded his system when he started having problems). It turns out that the 9200 was AGP 8x while the 8500 was AGP 4x and that was just enough to make a difference. The whole system died when I put the X850XT in, it wouldn't boot most of the time, spontaneous reboots constantly (Windows or Linux), Windows install would crash at the same point, etc. I swapped out the power supply with a 410W, all problems instantly vanished, and the system has been running fine since. I guess having to have a 410W isn't really that bad compared to some of the new stuff where they're starting to have 1000W PSU's though. I'm probably not going to upgrade any further from Athlon XP 3200+/Radeon X850XT for some time.

Today, all Windows drivers that I know of accomplish this with a spinlock. This means that an animated app grabs ALL available CPU cycles, even if the CPU actually needed to redraw each frame is trivial, and thus runs much hotter than it ought to for the amount of work being done.

Still, their power consumptions are not seperated by such a divide (a 60 watt differential would be generous). Honestly, to a great extent, this call for chip engineers to focus on poower consumption is equivalent to asking top fuel dragster engineers to focus on fuel consumption.
