NVIDIA GeForce GTX 680 Review: Retaking The Performance Crownby Ryan Smith on March 22, 2012 9:00 AM EST
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 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.
