SLI: GTX 660 Ti vs GTX 670 Conclusion
IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion as it represents our product rating specifically for the product tested, which may differ from future versions of the same product. Benchmark Reviews begins our conclusion with a short summary for each of the areas that we rate.
The NVIDIA GeForce GTX 660 Ti is presently sells for $300 online, while their GeForce GTX 670 video card currently costs $400. After reviewing the benchmark results for each graphics card in single and SLI configurations, there was plenty of evidence available to suggest that NVIDIA’s GeForce GTX 660 Ti delivers a much better value. In the games: Battlefield 3, Batman: Arkham City, Lost Planet 2, and Aliens vs Predator the single GTX 660 Ti trailed right behind the more expensive GTX 670. Given a modest overclock, it’s very possible for a gamer to save $100 and still enjoy GeForce GTX 670 levels of performance.
However, the SLI results didn’t follow the same patterns, and many of these same video games gave the SLI set of GeForce GTX 670′s a dominant lead ahead of the GTX 660 Ti SLI set. This was clearly the result of varying demands on memory and graphics processor, as well as the video cards ability to satisfy these demands. Not every benchmark test ended with GTX 660 Ti keeping pace with GTX 670 (such as Metro 2033, Crysis Warhead, and Unigine Heaven), and most SLI tests separated the cards’ performance even further apart.
The GeForce GTX 660 Ti is nearly identical to GTX 670 in every way except for the number of memory controllers, and performance in most games was just as similar when tested in a single card configuration. Unfortunately, the opposite was true for a few games, leaving GTX 660 Ti to trail behind a single GTX 670, and eating dust when compared in SLI. These results make for a difficult determination.
The bottom line is that it depends on your display resolution. A higher pixel count (larger display resolution) creates a significant difference between graphics card performance in the video games you’ll be playing. This was demonstrated with a single monitor configuration in our tests, using 1680×1050 (1.76MP) and 1920×1080 (2.07MP / +15%) display resolutions. Had we tested these products on multiple monitors, the results would have been exponentially greater and pushed the products even farther apart.
Aside from Crysis Warhead, almost every SLI benchmark favored GeForce GTX 670 by a significant margin. Our test results illustrated enough data to confirm that two GTX 670′s are far more capable of generating high frame rate performance than two GTX 660 Ti video cards… but still not by enough to justify the $100 difference per card. If you’re planning on building a single-card system and deciding between these two cards, it’s my opinion that an overclocked GeForce GTX 660 Ti is the way to go. However, if that plan is for a SLI computer system with multiple monitors, it may be worth the extra money to run a pair of GeForce GTX 670′s.
