Duh Voodoo Man's Geforce 6800 GT Mini-Review



Albatron Trinity Geforce 6800 GT

I guess that we 3D aficionados just have to resign ourselves to the endless cycle of upgrading our video cards on a yearly-or-so basis, along with the financial hit that comes with it. With new games appearing, like Doom3 and Half-Life 2, that push 3D rendering technology to the limits, this has just become part of the "price of admission" for the ability to play those new titles and experience the snazzy new visual effects they offer. There for awhile, it seemed like the latest video card technology was actually becoming cheaper with each succeeding generation, particularly if you stayed away from the absolute top-of-the-line cards, and looked at the models a click or two down the product line, but using the same GPU. Cards like the Geforce4 Ti4200 or the Radeon 9800 were good examples of this trend. The former often could be overclocked to the speeds of the more expensive 4400/4600 models, while the latter was just a BIOS flash away from becoming a full-fledged 9800 Pro. 3D enthusiasts on a limited budget (either by choice or necessity) could enjoy near world-class 3D performance while spending less than $250, and occasionally less than $200. Ah, those were the days....

Not any more. If you've priced the newest high-end cards from ATI and Nvidia, you know what I'm talking about. Such cards have taken a big jump in price from the previous generation that they are replacing--ATI's Radeon 9800 series and Nvidia GeforceFX 59xx cards. Right now, if you covet the new Radeon X800 XT or Geforce 6800 Ultra video cards, better plan on taking out a second mortgage or foregoing that new car purchase for a while! Well, OK, I'm exaggerating a bit here for effect, but $500 for a video card--and that's where most of these models start--borders on insanity, IMO. There's even a super-exclusive "Platinum Edition" of the X800 XT, with tweaked core and memory speeds, that goes for $600 and up!! Totally nuts!!! On top of that, both companies seem to be having some significant production ramp-up problems, based upon the number of models that are listed as "out of stock" when you price them at NewEgg, ZipZoomFly, GameVE and other well-known online resellers' web sites. It's quite common for the backordered cards to outnumber the in-stock models by a ratio of three or four to one! Needless to say, this scarcity of supply hasn't helped prices, either.

So what's the fiscally restrained video card buff to do?? Well, let's look at the tried-and-true strategy of moving down the product line to the next model tier. In this case, that translates to ATI's Radeon X800 Pro or Nvidia's Geforce 6800 GT cards. For the 6800 GT, this card differs from its more expensive sibling based only upon slightly lower core and memory clock settings. The X800 Pro has somewhat slower clockspeeds than the XT, and also cuts the number of pixel pipelines from 16 down to 12. Yes, the price is lower for these second-tier cards.....but not by all that much. You can still expect to pay over $400 for most of these cards, though some deals are available below the $400 threshold. Certainly, we're a long way from anything that might be considered a bargain, based upon video card price/performance relationships of the past couple of years.

So how about taking another step down the model ladder? Unfortunately, that has some pretty significant negative impact, from a performance standpoint. For ATI, it's quite a long way to the next rung--the X800SE, with only 8 pixel pipelines, and significantly lower core and memory clocks. Also, this card is currently quite hard to find, as ATI's reported strategy is to keep this as an OEM-only model and not offer it for retail sale. PriceWatch lists only about a half dozen resellers that carry it, with pricing in the low $300 range. And since the reported performance of the X800 SE is only marginally better than a 9800 XT, it really wouldn't make much sense as an upgrade for a current 9800 series card owner (namely me!) anyway.

The situation isn't any better for the Geforce cards. Dropping down from the 6800 GT to the plain 6800 series will cost you four pixel pipelines (down to 12 from 16), and significantly slower memory. Where the 6800 GT card use new DDR3 memory at 1000MHz, the 6800 uses regular DDR memory at 700MHz, and only 128MB of it. So clearly, it's not just playing the old "turn back your clocks" game when moving down the product line in these new cards. There are other, very significant differences that can't be countered simply through some judicious overclocking. And from what I've read, it doesn't appear that there's all that good of a chance of success in "modding" these cheaper cards through BIOS flashes or driver software mods. Some successes in turning on the four disabled pixel pipelines on a 6800 have been reported, but most of the postings I've seen describe the result as showing various degrees of visual defects, presumably due to "bad" pipelines. This certainly isn't surprising, given the shortage of saleable cards. I strongly suspect that there is a lot of "binning" of GPU chips going on, and the ones that are a pipeline or two short of the 16 good ones needed for a GT or Ultra end up as a plain 6800, with the bad pipes disabled. Similar situations with the X800 Pro and SE models seem very likely.

Indeed, it's become quite complicated to keep track of the differences between the various cards in these new product lines. Below is a summary table I've constructed, based upon the latest information I could find as of mid-November '04. Certainly, there are exceptions to the specs listed, with several video card manufacturers offering versions with slightly higher clockspeeds, or mixing up the core and memory hardware a bit. For example, Asus offers a 6800GT with 128MB of 700MHz DDR memory and a 6800 card with 256MB of 1GHz DDR3.....for over $400!! But the data shown should be a generally accurate depiction of what's out there right now:

So what's the best course of action for the Radeon 9800 or Geforce FX 5900 series owner who is considering an upgrade to the stellar performance levels offered by the new generation of high-end cards? Well, there's always the sane and rational approach of resisting the temptation to upgrade and just be satisfied with the still excellent performance levels of the card they already own and the knowledge that they are making the financially responsible decision. Yeah, I know--didn't work for me, either....

Once the decision to go ahead with the upgrade is made, which card makes the most sense? Well, that clearly depends on individual needs, desires and the size of your upgrade budget. But let's assume for the moment that you haven't yet lost all sense of fiscal restraint, and really don't want to lay out $500+ for a video card that you know will be essentially obsolete in 12 to 18 months. At the same time, you want significantly higher performance levels than your current card offers, otherwise the purchase isn't really an upgrade. In that case, your choices really boil down to the Radeon X800 Pro or the Geforce 6800 GT. The two cards are very comparable in overall performance, with the differences really being on a game-by-game basis. For example, the 6800 GT cards generally outperform the X800 Pro's in OpenGL games like Doom3, while the Radeon has an edge in many of the new DirectX games. So, unless you have a strong preference for ATI over Nvidia or visa-versa (and I don't), it's time to go shopping for the best deal.

After poking around in PriceWatch and at some of my favorite resellers' web sites, one deal really stood out to me--the Albatron Trinity Geforce 6800 GT at GameVE.com. I based this choice on several factors:

So with the choice finally made, I ordered the card on a Wednesday and took delivery the following Monday. Below are some photos of the retail package, courtesy of my favorite reseller's web site, NewEgg.com. Hey, they have better photos posted than I'll ever be able to take, so I trust they won't mind me using them here, especially with credit given and a hotlink to their site! One comment--the software bundle for this card is pretty anemic. Now, that was no issue for me, since the bundled games that come with these cards are usually fairly old and uninteresting. The best thing in the bundle, IMO, is WinDVD Creator. One change versus the photo shown below--my card came with "Arx Fatalis" rather than "Duke Nukem Manhattan Project". Frankly, I wouldn't be playing either of them, anyway, so no matter to me. Here are the photos:

Installation of the card and drivers was routine. First, I uninstalled the ATI Catalyst software that my old Radeon 9800 Pro had been using, then powered down and swapped cards. Next, I powered back up and installed the current 66.93 release version of the Nvidia "ForceWare" reference drivers, available at the Nvidia driver download page. After confirming that all was well and the card was running smoothly and stably, it was time to start running benchmarks....


Time to start bangin' out some numbers....
