eVGA GeForce 6800 Ultra Extreme Edition

Introduction, Specification, and Bundle

Back in May '04, NVIDIA introduced the GeForce 6800 Ultra Extreme Edition to counter the launch of ATi's Radeon X800 XT Platinum Edition, and gamers the world over took notice.  Just a few weeks earlier, the GeForce 6800 Ultra was unveiled, and at the time it was smoking through benchmarks like nobody's business.  Then, about a month later NVIDIA announces this new card and it's got a 16-Pipe NV40 core running a full 50MHz faster than the "stock" 6800 Ultra.  On top of that, it was said that some AIC partners may even ship cards with faster memory as well, offering even higher performance.  Today, we'll be taking a look at just such a card.

The eVGA GeForce 6800 Ultra Extreme Edition is basically a reference design GeForce 6800 Ultra with its core clocked at 450MHz and its on-board memory humming along at a speedy 1.2GHz (600MHz DDR).  This is the fastest NV40 based card to land in the HotHardware labs, as its memory is clocked a full 100MHz faster than even the reference GeForce 6800 Ultra Extreme Edition NVIDIA shipped to us for this article.  Since its initial release, NVIDIA has also improved GeForce 6 line-up performance, with updated Forceware drivers.  Needless to say we were eager to get the eVGA GeForce 6800 Ultra Extreme Edition installed to see just what she was made of. Here's what we found out.

* The operating system or APIs can impose limits, but the hardware does not limit shader program length.


eVGA struck a very good balance with their GeForce 6800 Ultra Extreme Edition's bundle.  Instead of including a slew of outdated utilities and older games with the card, eVGA has instead bundled one brand new game and includes only drivers, their proprietary ADM (Automated Driver Management) application, and NVIDIA's NVDVD player on the obligatory installation CD.  The game that eVGA is bundling with this card, at least until August 31, is the wildly popular FarCry.  It's good to see a new game, that's actually capable of showcasing some of the 6800's new features, shipping with eVGA's 6800 Ultra EE.  Kudos to eVGA - good choice!  Also included in the package are dual DVI-to-DB15 adapters, dual Molex power cable splitters, and a single S-Video cable.  Lastly, there is a user's manual, a couple of case badges, and a certificate of quality signed by the Director of Technical Marketing, their Chief Engineer, and two Quality Managers.  The certificate details what testing was done prior to boxing up the card and states, "This product comes with a 24 hour next business day replacement should something happen to your card."  That's a very comforting statement to read, when you've just dropped a mint on a new high-end video card, don't you think?
