Full Disclosure: The product sample used in this article has been provided by ASUS.

Many computer hardware enthusiast recall when NVIDIA unleashed their GeForce GTX 580 video card onto the gaming landscape back on November 2010, setting the bar so high the closest threat to the $500 price point was a combined pair of the competition's best graphics cards. Under two years later, NVIDIA returns with a 150W mid-range solution that beats their former flagship. Built upon the NVIDIA GK104 GPU, the GeForce GTX 660 Ti offers the same high-end features found on the top-end GTX 680, but with a much more affordable price tag. In this article Benchmark Reviews tests the ASUS GeForce GTX 660 Ti DirectCU II TOP, model TI-DC2T-2GD5.

Of the many platforms available for gamers to enjoy video games, there's no question that the highest quality graphics come from PC. While game developers might not consider PC gaming as lucrative as entertainment consoles, companies like NVIDIA use desktop graphics to set the benchmark for smaller more compact designs that make it into notebooks, tablets, and smartphone devices. NVIDIA's Kepler GPU architecture is an example of this, delivering unprecedented performance while operating cooler and consuming far less power than previous flagship discrete graphics cards.

ASUS further extends GeForce GTX 660 Ti's functionality with proprietary features available only on their brand of video cards, which for the GTX 660 Ti series include: DirectCU-II Standard (TI-DC2-2GD5), DirectCU-II OC (TI-DC2O-2GD5), and DirectCU-II TOP (TI-DC2T-2GD5). Clocked to 1137 MHz, the ASUS GeForce GTX 660 Ti TOP model features a 7% faster GPU boost speed, or 157 MHz over the reference design. Its DirectCU-II design yields 20% cooler performance, with 9dB less audible fan noise. Combined with the ASUS GPU Tweak software, GTX 660 Ti DirectCU-II TOP utilizes digital DIGI+ VRM with 6-Phase Super Alloy Power (SAP) electronic components to achieve even greater GPU clock speeds with stable overclocked performance.


NVIDIA's GeForce GTX 660 Ti graphics card is designed around the same 28nm GK104 Kepler GPU architecture found in the GeForce GTX 680 and 670, and replaces NVIDIA's GeForce GTX 570 series in terms of performance. NVIDIA GPU Boost enables 1344 CUDA cores to dynamically adjust power and clock speeds based on real-time game or application demands. GeForce GTX 660 Ti's core count and clock speeds are identical to GTX 670, with the same being true for the card's 2GB memory buffer - albeit reduced to 192-bit bandwidth. Designed to occupy the $300 price point, GeForce GTX 660 Ti competes on cost with AMD's Radeon HD 7870 but matches performance with the more expensive Radeon HD 7950. In this article, Benchmark Reviews will test the GeForce GTX 660 Ti and discover how this combination performs with DirectX 10/11 generation video games.

In addition to a new and improved Kepler GPU architecture with NVIDIA GPU Boost technology, the GeForce GTX 660 Ti video card delivers further refinement to the user experience. Smoother FXAA and adaptive vSync technology results in less chop, stutter, and tearing in on-screen motion. Overclockers might see their enthusiast experiments threatened by the presence of NVIDIA GPU Boost technology, but dynamically adjusting power and clock speed profiles can be supplemented with additional overclocking or shut off completely. Adaptive vSync on the other hand, is a welcome addition by all users - from the gamer to the casual computer user. This new technology adjusts the monitor's refresh rate whenever the FPS rate becomes too low to properly sustain vertical sync (when enabled), thereby reducing stutter and tearing artifacts. Finally, NVIDIA is introducing TXAA, a film-style anti-aliasing technique with a mix of hardware post-processing, custom CG file style AA resolve, and an optional temporal component for better image quality.

These things are gonna drive market prices down. With such stellar performance from these GTX660Ti cards, AMD will have to do something.

I think the BOOST bios is suppose to help in addressing that in the 7950 series and the GHZ cards in the 7970 series

I didn't read the entire article in depth, so if you have already stated this, excuse the redundancy.

Is the GTX 660 the same card as the 660ti TOP except for OCing?

GTX 660 is/should be GTX 660 Ti, and the TOP edition is an ASUS special product that uses a very high factory overclock.

The graph representation you are using looks ugly and are difficult to read. It's bit confusing to read the graph, for instance I read the figure on bar, ok, but what is that figure for? I have refer the bottom of graph again to find what card it is for.
Maybe I am over-reacting, but it can be much simpler.

Why don't you give us an example of how it could be done better?

Hi Sire,
I am glad you took a notice of it and I hope you are not joking when you are asking for example.
Maybe something like this:

Sire, I am in no way saying anything about the content of the review. It's just about the graph. Cheers.

I tend to agree with this. It's much easier to read. I've never liked the BMR graphs.

Which is odd, since you've written for us and know that you're free to use/make any graph you like. Of course, then again, you never really made it into the demanding reviews that require charts.

Right I've never created graphs or I may have suggested a different style. It's not a huge deal either. but the clearer the graph, the easier it is for readers to glean information at a glance.

What's not nice? Olin and I are both making factual comments here. Unless I've said something mean, I see nothing here that would cause me to think anything otherwise. It's good someone pointed out the graphs could be more clear. I think the reason no one has is that it is true, they are a little hard too read, and also that it's not a deal breaker. So no one said anything.

I have always found the graphs used by benchmark reviews to be hard to read the problem is matching colors from the key to the graph, it's often hard to determine the dark colors from one another in particular when they add more cards to the mix.

I mean, the review is ok. the board is good, even the comptetition is not bad.
And the graph is ok. not brilliant, but fine. Me genius? neah.

After reading the comments first, I was intrigued to see the graphs.
I can't say I remember taking notice of them if ever the times I have read any review.
And I think they are fine, even the color coded part. I can understand the color brown and grayish black were a bit difficult to discern, but once I got they are in order on both top and bottom, it wasn't too challenging.
Bottom line: Graphs nice and clear.
One mans opinion.
