Portal 2

Portal 2 continues the long and proud tradition of Valve’s in-house Source engine. While Source continues to be a DX9 engine, Valve has continued to upgrade it over the years to improve its quality, and combined with their choice of style you’d have a hard time telling it’s over 7 years old at this point. Consequently Portal 2’s performance does get rather high on high-end cards, but we have ways of fixing that…

Portal 2 - 2560x1600 - Very High Quality + 4xMSAA/16xAF

Portal 2 - 1920x1200 - Very High Quality + 4xMSAA/16xAF

Portal 2 - 2560x1600 - Very High Quality + 4xSSAA/16xAF

Portal 2 - 1920x1200 - Very High Quality + 4xSSAA/16xAF

Portal 2 ends up being the strongest lead yet for the GTX 680, with the GTX 680 taking a 17% lead at 2560. What’s especially interesting though is performance in the bonus round with SSAA enabled – the GTX 680 takes a wholly unexpected and completely stunning 44% lead over the 7970. In fact it beats out everything here, including the GTX 590 and Radeon HD 6990. Meanwhile the lead over the GTX 580 is even more amazing, with the GTX 680 leading by 67% at these settings.

As it stands the GTX 680 is the first single-GPU card to do better than 60fps, and it does so in a landslide. All things considered, for a lack of memory bandwidth and ROP changes compared to Fermi GTX 680 does extremely well here.

    Wondering if you guys could also add a benchmark for one the current crop of 1ghz core 7970s that are available now (if you've tested any). Otherwise, great review.

    With everything being said by Nvidia, I thought this would be a Geforce 8k series class jump, while its really nothing close to that and trades blows with AMDs 3 month old card. GCN definitely had headroom so I can see lower priced, higher clocked AMD cards coming out soon to combat this. Still, I'm glad this will bring things down to sane prices.

    Well to be honest, this wasn't supposed to be Nvidias successor to the GTX 580 anyway. This graphics card replaced the GTX 560 Ti, not the GTX 580. GK 110 will replace the GTX 580, even if you can argue that the GTX 680 is now their high-end card, it's just a replacement for the GTX 560 Ti so I can just dream about the performance of the GTX 780 or whatever they're going to call it. ;)

    I didn't know that, thanks. Ugh, even more confusing naming schemes.

    If this is supposed to replace the 560 Ti then why does it cost $500 and why was it released before the low-end parts instead of before the high-end parts?
  • MarkusN - Thursday, March 22, 2012 - link

    It costs that much because Nvidia realized that it outperforms/trades blows with the HD 7970 and saw an opportunity to make some extra cash, which basically sucks for us consumers. There are those that say that the GTX 680 is cheaper and better than the HD 7970 and think it costs just the right amount, but as usual it's us, the customers, that are getting the shaft again. This card should've been around $300-350 in my opinion, no matter if it beats the HD 7970.

    Nah, they aren't obligated to give more then what the market will bear, no sense in starting a price war when they can have much fatter margins, it beats the 7970 already it's just enough.

    Now the ball is in AMD's court let's see if they can drop prices to compete $450 would be a nice start, but $400 is necessary to actually cause significant competition.

    This whole thing is so nutso but everyone is saying it.
    Let's take a thoughtful sane view...
    The GTX580 flagship was just $500, and a week or two ago it was $469 or so.
    In what world, in what release, in the past let's say ten years even, has either card company released their new product with $170 or $200 off their standard flagship price when it was standing near $500 right before the release ?
    The answer is it has never, ever happened, not even close, not once.
    With the GTX580 at $450, there's no way a card 40% faster is going to be dropped in at $300, no matter what rumor Charlie Demejerin at Semi0-Accurate has made up from thin air up as an attack on Nvidia, a very smart one for not too bright people it seems.
    Please, feel free to tell me what flagship has ever dropped in cutting nearly $200 off the current flagship price ?
    Any of you ?!?

    Because nVidia decided to screw its costumer and nickle and dime them. That's why. All because 7970 underperformed and nv could get away with it.
  • JarredWalton - Thursday, March 22, 2012 - link

    Or: Because NVIDIA and AMD and Intel are all businesses, and when you launch a hot new product and lots of people are excited to get one, you sell at a price premium for as long as you can. Then supply equals demand and then exceeds demand and that's when you start dropping prices. 7970 didn't underperform; people just expected/wanted more. Realistically, we're getting to the point where doubling performance with a process shrink isn't going to happen, and even 50% improvements are rare. 7970 and 680 are a reflection of that fact.
