While the industry has definitely firmly attached itself to PCI Express, many enthusiasts out there are still running AGP based systems. The cost of keeping up with the pace of technology is certainly steep, so upgrade cycles for some people stretch quite a bit longer than others. Even in cases where a technophile is able to upgrade frequently, no savvy user would just throw out last year's top of the line. If that AGP box doesn't become a hand-me-down to a friend or relative, keeping an older system around for some LAN gaming when guests come to visit is definitely a nice alternative to the trash heap.

Whatever the situation, there are plenty of people out there looking to extend the life of AGP systems in one way or another. And if gaming is a primary function of the computer, graphics card upgrades are most often the way to go for users who want the most bang for the buck. Luckily, NVIDIA hasn't left the users behind. Today, the GeForce 7800 GS makes its debut as NVIDIA's first AGP 7 Series product.

It is unknown whether further updates to the AGP lineup will present themselves, but NVIDIA has said that they will be able to adapt to the demands of the market. This part, like all other recent NVIDIA AGP parts, is made possible by use of their HSI (High Speed Interconnect), which is capable of connecting AGP and PCI Express busses together. The G70 part used on the 7800 GS is a native PCI Express part, and NVIDIA aren't planning on fabbing any more native AGP parts.

Some of you may remember that we took a look at a PCI Express 7800 GS (which will never exist) when an NVIDIA partner accidentally gave away an engineering sample instead of a 7800 GT in a promotion. The specifications of the AGP 7800 GS are not very far off the part that we tested a few months back, but on the AGP platform, there is considerably less competition at the top. Add to this the fact that some manufacturers are shipping boards with higher than stock core and memory speeds, and this part could definitely push an AGP system as far as it is likely to go.

    As I said in my earlier post. Head over to Tom's HW for comparison with a 6800 Ultra, the 7800 GS beats the 6800 Ultra AGP in almost all the latest games. The X850XT is still tops, but can't do the eye candy. Reply

    We've got full retail boxes from both BFG and EVGA.


    For the purposes of these tests, we underclocked a card to the minimum speed NVIDIA is endorsing.

    I'm a little shocked at the decision to ignore the actual speed these cards run at out of the box, and instead show an artificially limited card -- exclusively.

    I wouldn't have minded seeing the "published spec" score, but not at the expense of knowing what you get if you walk into a store and walk out with one of these cards. Without that, this article is glaringly incomplete. I'm left little more informed about how an actual retail product performs than I was before I read it. That doesn't sound like AnandTech.

    I agree that the reviews are subpar. I think anand should not be delegating as many reviews as he has been. You can ALWAYS tell which reviews he does from the moment you start reading it (a good thing). I guess he is just to busy these days to do more of them. Reply

    Where is the 6800 Ulra or 6800GT in that review? How about a 6600GT? Come on guys... these are the cards that people who would consider buying a 7800GS own right now. Not including a 6800 or 6600 series in that review makes no sense at all.

    On a side note... AT has changed since I started visiting... I used to be able to get all the info I could ask for right here... now I have to visit 5 other forums to get the info I want, and that's not a good thing.

    here here.. this article is weak; run the cards at their OC speed, and then LABEL the REFERENCE Speed 7800 GS on the charts, since this is MISLEADING and *NOT* intuitive in comparisons when putting money down on the table.

    From a competition performance-cost standpoint, let's talk about bang for the buck here. This isn't a PREVIEW, this is about a card coming out in days.

    How does the X1600XT 256MB, 6660GT 128MB, 6800 128MB rate in the $130 range.
    Then its the sub 200$ range with the 6600GT or 6800 256MB versions.

    We can all go thank Tom's HW site for the 2005 VGA charts to get a rough ball estimate due to the X850XT PE (which was not 210$ but rather in the $400+ range (from using pricegrabber). Not only that but they do compare the 7800GS against the 6800U and the BFG card is modestly beating the old tech. For the 300$ target price of the 7800GS AGP, there is a vast wasteland and no competition pricewise, but I feel its not justified to say it will drop 6800GT/U prices since it is no longer being manufactured (still going to be rare, and same performance, so why even bother getting an old large hot stinker of a card on E-bay-like services when you can get brand-spanking new tech?)

    I'm still leering of why nVidia cannot see to get HDR and AA/AF to play nice, so I personally don't see much advantage in upgrading from a 6600GT / 6800 GT / U part just for SM 3.0. If the 7800GS is ~30% faster than a 6600GT, ~11% faster than a 6800 GT, and barely ekes out victory over a 6800 U, it doesn't do justice to upgrade unless you need to make the leap from TurboCache or integrated. I do hardware (& sys building) recommendations for many people and want to steer them in the right direction and make them feel they got the best value. Will this make people put off buying an M2 & PCI-e mobo for another year and stick with AGP? I'm not in the business of making predictions, but for me personally, I would rather get an X2 chip, mobo, and X1900 or 7800GTX (or maybe even the refresh to choose from), possibly an Creative X-Fi entry (but highly doubtful, shrug to the 5.1 audiophiles because there is a lack of a stand out digital spdif 5.1 headset - this boggles my mind and is another side topic) and 2GB of DDR2-667 RAM right about xmas 2006. I never find a truly good integrated PC builder that satisfied my DIY urges.

    The 6800 Ultra looses the lead in comparison to 7800 GS. Head over to toms hardware to see benchmark scores. I have an Opteron 146 w/ socket 940 and 2GB ECC-DDR400 that I received from work, but it has an ATI 9600SE. The 7800 GS is exactly what I have been waiting for since upgrading to a 939 with PCI-E is useless and will cost me more than a 7800 GS. The 7800 GS should give my system usefull life for a year at least, maybe more and it will be half the price of a 6800 Ultra.

    I'd be interested in a comparison between the XT1600 and the 7800 GS AGP cards. They are my 2 candidates for a low power, high performance AGP card for my HTPC. I think many other HTPC owners would be interested in this as well, especially how the HDTV performance and quality compares on older CPUs. Reply

    Wish you guys had included a 6800GT or Ultra in here. Reply

    Could you add one more line showing how the card benches at the EVGA default overclock? Or maybe do your own overclock and test?

    Since this is the last bastion of AGP performance, I don't think any of us AGP users will want to stock clock this..
  • DrZoidberg - Thursday, February 02, 2006 - link

    Yeah i cannot see why Anandtech decided not to show default factory o/c scores from evga. Sure if AT wanted benchmark with 7800gs underclocked but ALSO include 7800gs standard retail overclock benchmark.

    I mean the consumer who buys the evga 7800gs is not going to underclock the card by 20% from 460/1.35 to 375/1.2 and lose 20% performance.
