The GeForce 8800 Ultra

Physically, the layout of the board is no different, but NVIDIA has put quite a bit of work into their latest effort. The first and most noticeable change is the HSF.

We have been very happy with NVIDIA's stock cooling solutions for the past few years. This HSF solution is no different, as it offers quiet and efficient cooling. Of course, this could be due to the fact that the only real changes are the position of the fan and the shape of the shroud.

Beyond cooling, NVIDIA has altered the G80 silicon. Though they could not go into the specifics, NVIDIA indicated that layout has been changed to allow for higher clocks. They have also enhanced the 90nm process they are using to fab the chips. Adjustments targeted at improving clock speed and reducing power (which can sometimes work against each other) were made. We certainly wish NVIDIA could have gone into more detail on this topic, but we are left to wonder exactly what is different with the new revision of G80.

As far as functionality is concerned, no features have changed between the 8800 GTX and the 8800 Ultra. What we have, for all intents and purposes, is an overclocked 8800 GTX. Here's a look at the card:



While we don't normally look at overclocking with reference hardware, NVIDIA suggested that there is much more headroom available in the 8800 Ultra than on the GTX. We decided to put the card to the test, but we will have to wait until we get our hands on retail boards to see what end users can realistically expect.

Using nTune, we were able to run completely stable at 684MHz. This is faster than any of our 8800 GTX hardware has been able to reach. Shader clock increases with core clock when set under nTune. The hardware is capable of independent clocks, but currently NVIDIA doesn't allow users to set the clocks independently without the use of a BIOS tweaking utility.

We used RivaTuner to check out where our shader clock landed when setting core clock speed in nTune. With a core clock of 684MHz, we saw 1674MHz on the shader. Pushing nTune up to 690 still gave us a core clock of 684MHz but with a shader clock of 1728MHz. The next core clock speed available is 702MHz which also pairs with 1728MHz on the shader. We could run some tests at these higher speeds, but our reference board wasn't able to handle the heat and locked up without completing our stress test.

It is possible we could see some hardware vendors release 8800 Ultra parts with over 100MHz higher core clocks than stock 8800 GTX parts, which could start to get interesting at the $700+ price range. It does seem that the revised G80 silicon may be able to hit 700+ MHz core clocks with 1.73GHz shader clocks with advanced (read: even more expensive) cooling solutions. That is, if our reference board is actually a good indication of retail parts. As we mentioned, we will have to wait and see.

    Let this be a lesson kids, buy an ATI card, and an AMD processor or two.

    Even the low end stuff, for your mom or your kids machine.

    The reason why the CPU market is so awesome right now is because intel felt real pressure from amd and they had to respond with a superior product at lower prices or face a continual market share loss.

    We now see nvidia's true colors, the sky's the limit on the prices, and they quite surely, could have released a product with far more performance, at a lower price point, had AMD been simply been putting pressure on them.

    If anyone buys this card, you are wholeheartedly supporting $1000 dollar retail graphics cards, that will increase in performance incrementally over the years instead of quantum leaps, at a fair, and still profitable cost...

    Mise well just buy a wii im thinking...

    I'm not buying an AMD processor or graphics card simply because they offer competition to Intel or Nvidia. I will buy an AMD product when they offer simple superior performance to the competition again. At the $300 I paid for my 8800GTS, there is nothing that comes close in performance for the money.

    Don't tell me that ATI didn't try some insane pricing when they had the lead.

    AMD would love to join NVIDIA on this. Don't forget about the FX series of processors or the 4x4 program.

    Rather than pressure companies to build hardware that doesn't cost much, let's encourage them to build hardware that's worth the price they put on it.

    There is a market for high end hardware. There is no reason NVIDIA, AMD, and Intel shouldn't satisfy that market. But there's no point in charging $830 for performance we can get for $650 just because people will buy it.

    Great point. Yeah, lets be a charity for AMD. Come on. Where are these people coming from??? When AMD offers a competitive part again for a decent price, I will buy from them again. If Intel starts offering parts I feel are not worth it, I wont buy from them.

    I have 8800GTX in SLI and am running at 629/1000 and these are just plain old air cooled GTX parts. NVidia is nuts on this Ultra. It wont sell well at this price and they will either have to put more value or drop this down to regular GTX pricing.

    THe market adjusts itself and doesnt need political statements from ideological consumers to drive it. Of course if you choose to spend your money that way, more power to you! One could argue that it keeps AMD weak though. If they know they have a comfortable revenue stream for substandard parts, the can rest. Remember... they rose to challenge Intel from NOTHING, not from a flow of "charity" revenue.

    I think they are following Murphy's Law: It is morally wrong to allow suckers to keep their money. They made changes at minimal cost to a product, slap a high price on it, and see if anyone is dumb enough to bite. When sales numbers drop off, they cut the price, and probably end up closer to $700 where the performance should leave it.

    I don't blame nVidia for making it, I just laugh at anyone who buys it.

    Yeah, I don't think its worth that much more $$ just for that little extra edge in performance.

    HELLOOO... I CAME FROM THE FUTURE :v ...... YOU CANT RUN 4K IN THIS CARD :v .... bye
  • felicityc - Tuesday, January 11, 2022 - link

    I come from the even further future. A magical fairy wizard has blessed nvidia with the ability to create price pressure without doing anything by themselves or even pretending to sell sports-model GPUs.

    Also, SLI is dead, you still can't run Crysis (it looks pretty good on those 2x 8800 GTX) because it breaks on newer versions of Windows, the mortgage market is about to crash in a year or so, and you should invest in Bitcoin.

    Also, AMD saves the CPU market briefly and AMD rebrands as ATI, except as AMD.

    It's been a weird few years.
