DiRT 3

For racing games our racer of choice continues to be DiRT, which is now in its 3rd iteration. Codemasters uses the same EGO engine between its DiRT, F1, and GRID series, so the performance of EGO has been relevant for a number of racing games over the years.

With AMD’s recent performance boost in DiRT 3 the game has largely equalized AMD and NVIDIA, and at no point is this better demonstrated than with the launch of the GTX 660 Ti. At 1920 the GTX 660 Ti and 7950 are virtually tied, while the GTX 660 Ti falls behind at 2560 as it runs out of memory bandwidth.

Meanwhile the factory overclocked cards see some modest gains here, with the Gigabyte pulling ahead of the others with a 9% performance increase. In fact it’s only a few percent off of the GTX 670, which may be a reflection of the importance of the power target since the two also have similar a similar power draw.

Looking at the minimum framerates that 660/7950 standoff finally breaks in NVIDIA’s favor. Though a lack of memory bandwidth continues to pose a problem at 2560.

    If they can't supply it - it cannot lower competitor prices, and can't be bought, so they make little or no money, and everyone else buys the available competitors product.
    Why doesn't AMD release a card that drives down the 680's price $170 per card and makes nVidia give away 3 free games with it too ?
    That would make too much sense for amd and we consumers and some competition that crushes evil corporate profiteering nVidia, so AMD should do it.
    (roll eyes)
    To answer your question> nVidia is being nice not draining all the red blood from amd's jugular since amd is bleeding out so badly already that if nVidia took them out a million raging in 3d fanboys would scream for billions in payola in a giant lawsuit they protest for in front of the UN and the IMF and the International Court and the 25k persons traveling EURO unelected power bureaucrats.
    So instead of all that terribleness and making amd fans cry, nVidia is nice about it.

    This card at 249$ would be very bad for AMD but not very good for Nvidia either. Considering how close it already is to it's bigger brother, it would probably cut a good percentage of gtx 670 sales.

    So yeah, 249$ might seem a good price for US but they don't want to harm themselves either.

    What does TI mean?

    Where is the GTX 660? So its really a 670 with a hand chopped off?
  • ericloewe - Thursday, August 16, 2012 - link

    TI means something along the lines of "We'll release a crap version later on that only OEMs will buy, called the GTX 660."

    I think it still means "Titanium" version of a chip which was supposedly better than the non-Ti.
  • MrSpadge - Sunday, August 19, 2012 - link

    It means "We can't figure out how to distinguish our products using 3 decimal numbers and up to 3 letters in front of it (or the lack thereof), so we'll add some more letters".

    in the anand review of the 450 where Nvidia first showed the lopsided memory bus arrangement it was noted that CUDA apps would not recognise the full memory complement.

    has this now been fixed?
  • Ryan Smith - Thursday, August 16, 2012 - link

    Yes. That was fixed almost immediately.

    thanks Ryan
