Nvidia GeForce GTX 260/280 Review

Specifications: Better!

As is often the case, Nvidia is making two cards available for its launch – a very-high-end version, the GeForce GTX 280, and a slightly more affordable but still high-end card, the GeForce GTX 260. Let’s look at the other characteristics of these cards compared to their competitors.

With 1,400 million transistors, and especially at 576 mm², Nvidia has created another monster – the biggest GPU ever produced, breaking the record, impressive as it was, of the G80 (16% smaller)! Yet this value ought to have remained constant over the generations (it has even been diminishing in recent times for “general-public” CPUs). Clearly production of the GT200 is extremely expensive for Nvidia, even if the conservative engraving depth is what explains the existence of a chip like this today.

Another notable point is that by continuing to use GDDR3, Nvidia is now not one but two generations behind in this department, since GDDR5 will make its appearance with the soon-to-be-released Radeon HD 4870. But though that is worth mentioning, thanks to the 512-bit bus, the increase of memory bandwidth is still 64% compared to the 8800 GTX’s 86.4 GB/s. And we’re finally seeing the debut of a high-end card with more than 512 MB of usable memory (not counting the relatively old and not widely distributed 8800 Ultra)! With 1 GB (and 896 MB for the GTX 260 – a good thing), performance at 2560*1600 resolution should finally be able to hold up!

Finally, the frequencies used are fairly conservative, especially with the ALUs, which are slower than on the 8800 Ultra, among others.

    what a POS, the 9800gx2 is $150+ cheaper and performs just about the same. Let's hope the new ATI cards coming actually make a difference

    woow,.... that's the new "high end" gpu????
    lolz.. 3870 x2 wil get cheaper... and nvidia gtx200 lies on the shelves providing space for dust........
    (I really expectede mmore from this one... :/ )

    Pretty disappointing. And here I was thinking that the gtx 280 was supposed to put the 9800gx2 to shame. Not too good.
  • cappster
    Both cards are priced out of my price range. Mainstream decently priced cards sell better than the extreme high priced cards. I think Nvidia is going to lose this round of "next gen" cards and price to performance ratio to ATI. I am a fan of whichever company will provide a nice performing card at a decent price (sub 300 dollars).
  • njalterio
    Very disappointing, and I had to laugh when they compared the prices for the GTX 260 and the GTX 280, $450 and $600, calling the GTX 260 "nearly half the price" of the GTX 280. Way to fail at math. lol.

    It is going to get owned by the 4870x2. In some cases the 3870x2 was quicker - not many, but we are talking 640 shaders total vs. 1600 total for the 4870x2.
  • MooseMuffin
    Loud, power hungry, expensive and not a huge performance improvement. Nice job nvidia.

    This should be great news for AMD. The 4870 is rumored to come in at 40% above the 9800GTX so that would put it at about the 260GTX range. At $300 it would be a much better value. Plus AMD was expecting to price it in the $200s so even if it hits low, AMD can lower the price and make some money.

    i think i'll get a 8800ultra. i'll be safe for the next 5 generations of nvidia! try harder nv crew
