Final Words

It's taken three generations of revisions, augmentation, and massaging to get where we are, but the G70 is a testament to the potential the original NV30 design possessed. Using the knowledge gained from their experiences with NV3x and NV4x, the G70 is a very refined implementation of a well designed part.

With a max of three times the MADD throughput, 50% more pixel pipes, and 33% more vertex power than 6800 Ultra, the GeForce 7800 GTX is a force with which to be reckoned. Putting this much processing power into a package that pulls less juice from the wall than a 6800 Ultra is quite a feat as well. The 300+ million transistors fabbed on a 110 nm process are quite capable, and NVIDIA's compiler technology is finally mature to the point of handling all games with no shader replacement.

Adding transparency AA and further enhancing the efficiency of their PureVideo hardware will be the most tangible feature additions of the GeForce 7800 GTX. The tweaks in the pipeline really only come in performance numbers rather than feature enhancements. As there has been no DirectX update since the last part, NVIDIA has opted not to introduce any extra features. Their reasoning is that developers are slow enough to adopt DirectX changes, let alone a feature that would only run using OpenGL extensions.

Even though features haven't been added to the vertex and pixel shaders directly, the increased power will allow game developers more freedom to generate more incredible and amazing experiences. Though not seen in any game out now or coming out in the near term, the 7800 GTX does offer the ability to render nearly "Sprits Within" quality graphics in real-time. Games that live up to this example (such as Unreal Tournament 2007) still have quite a ways to go before they make it into our hands and onto our hardware, but it is nice to know the 7800 GTX has the power to run these applications when they do come along.

It is quite difficult to sum up this launch. From what is essentially a very thorough refresh of NV4x, we've got something that is more than the sum of its parts. The GeForce 7800 GTX is capable of smooth frame rates at incredibly high resolutions. Succeeding in bringing hardware and compiler together for a solution that does a better job of keeping the hardware busy than previous generations is definitely one of the most important aspects of this part. Eliminating shader replacement and performing this well is no feat to be underestimated.

Aside from the well executed hardware, NVIDIA has pulled off an incredible launch with availability right now. A quick look in our RealTime Price Engine shows several brands already available as low as $569. We can't stress enough how happy we are with NVIDIA's push to provide product in the retail market on the same day the product is announced. ATI really needs to follow suit on this one with their upcoming Crossfire launches.

For $600 we would like to see 512MB onboard, but with the current gaming landscape we certainly agree that more than 256MB is not an absolute necessity. But the GeForce 7800 GTX would have no reason to exist right now if not to accommodate future titles that will be more taxing than current games.

Overall, we consider this a successful launch. Aside from the performance of the 7800 GTX, we can infer that the PS3's RSX will be even more powerful than the G70. As RSX will be a 90nm part and will still have some time to develop further, the design will likely be even easier to program, faster, and full of more new features.

    Dude just stfu......we are here to comment what we want and say it freely......minus threats and name calling....as i said before this card is not for gamers...maybe elite gamers that have a monitor that does these resolutions but most gamers i know have went to lcd and i have yet to see any lcd[im sure there are some]do these resolutions so this card really is a card for crt elite gamers......lol with those resolutions on a 21 inch monitor you would need binoculars as glasses to play the game....the tanks on bf2 would be ant like small....

    I am SO glad that Anand remains in business despite all the bitches that are in these comment sections.

    Those who are complaining that they should have reviewed at lower resolutions should think for a minute. First of all you are talking about a 600 buck card, most people who have that kind of money to spend on a card also have a monitor that is capable of 1600x1200 or better. Also benchmarking at any lower resolution on a card like this in todays games is almost pointless as you are almost entirely CPU bound at those resolutions. Do you really want to see page after page of 1024x768 charts that differ by only 4-5 percent at the most?

    Also give the editors a break when it comes to writing these articles. As others have said this is not a subscription site and given the number of visitors and the quality of the articles I'm amazed, and gratified, that the people of Anandtech keep putting out article after long article despite all the winning that goes on over spelling mistakes and graph errors that more often than not are corrected within a few hours.

    That's a really great comparison, #112, especially seeing as how we pay for AnandTech and any problems with it could leave us stranded in the middle of nowhere. And so witty, too!

    Jarred, ah, thanks.

    Dear Mr. Fink,
    I am sorry to hear about the problems you have had with your vehicle breakdowns. You see, our quality inspector was on vacation that week, so we just shipped our vehicles strait off the assembly line. Please cut us a little slack, as we usually build much better vehicles.

    Sincerly,
    Buncha Crap,

    my question is how did they do hi res 2048x1536 when the card is only single-link DVI? Shouldn't either an analog connection or dual-link be necessary? Reply

    #108 - what do you want, a $2000 CPU to go with your $1200 in GPUs? =P Reply

    so dual display is still not available with dual 7800s?!?!?!?!? Reply
