EVGA GeForce GTX 660 Ti SuperClocked Video Card Review
By Gabriel Torres on August 16, 2012


Introduction

Hardware Secrets Golden Award

The new GeForce GTX 660 Ti, which is being released today, is the latest GPU from NVIDIA, and EVGA is providing six different video card models based on this new GPU. Let’s see how the SuperClocked model fared on our tests.

In the table below, you can see the six models EVGA is releasing.

At USD 300, the GeForce GTX 660 Ti is targeted to the user who is looking for a relatively affordable high-end video card. Its main competitor is the Radeon HD 7870 GHz Edition.

The new GeForce GTX 660 Ti uses the PCI Express 3.0 interface, similarly to its main competitor, while the GeForce 560 Ti and the GeForce GTX 570, which we also included in our comparisons, use the PCI Express 2.0 interface. This new GPU has an automatic overclocking feature that increases the core clock from 915 MHz to 980 MHz when more performance is needed (980 MHz to 1,059 MHz on the EVGA’s SuperClocked model).

In the table below, we compare the main specifications for the video cards included in our review. The prices listed below were researched at Newegg.com and do not include rebates. The price of the GeForce GTX 660 Ti is the one advertised by NVIDIA, while the price for the EVGA GeForce GTX 660 Ti SuperClocked is the one advertised by EVGA.

You can compare the specs of these video cards with other video cards by taking a look at our “AMD ATI Chips Comparison Table” and “NVIDIA Chips Comparison Table” tutorials.

Now let’s take a complete look at the EVGA GeForce GTX 660 Ti SuperClocked.

The EVGA GeForce GTX 660 Ti SuperClocked

Below we have an overall look at the EVGA GeForce GTX 660 Ti SuperClocked. It requires two six-pin auxiliary power connectors.

The cooler uses a 60 mm radial fan placed beside an aluminum heatsink. The heatsink features a copper base. See Figures 4 and 5. The GeForce GTX 660 Ti has a TDP of 150 W.

In Figure 6, you can see the video card with its cooler removed. We were impressed by how short the printed circuit board is, at 6.8” (172 mm). The video card, however, is a little longer, at 9.5” (240 mm), because of the fan.

It uses a voltage regulator with four phases for the GPU and two phases for the memory chips. The voltage regulator circuit uses a digital design and is controlled by an NCP5392P chip. All coils use ferrite cores and all capacitors are solid.

Figure 7: Voltage regulator

The reviewed video card uses eight Hynix H5GQ2H24AFR-R0C GDDR5 chips, each one storing 2 Gbit of data, comprising the 2 GB of memory available on this video card. Six of these chips are located on the component side of the printed circuit board, each connected to the GPU through a 32-bit lane, creating the 192-bit datapath that is available. The other two chips are located on the solder side of the printed circuit board and apparently share the datapaths used by two of the chips that are available on the component side of the board. There are spaces for soldering four additional memory chips, so the 3 GB version of this video card most likely uses the same printed circuit board but has all of the spaces populated.

The chips that come soldered on this video card can run up to 6 GHz. On this video card, they are accessed at 6,008 MHz.

Before seeing the performance results, let’s recap the main features of this video card.

Main Specifications

The main specifications for the EVGA GeForce GTX 660 Ti SuperClocked include:

How We Tested

During our benchmarking sessions, we used the configuration listed below. Between our benchmarking sessions, the only variable was the video card being tested.

Software Configuration

Driver Versions

Software Used

Error Margin

We adopted a 3% error margin. Thus, differences below 3% cannot be considered relevant. In other words, products with a performance difference below 3% should be considered as having similar performance.

StarCraft II: Wings of Liberty

StarCraft II: Wings of Liberty is a very popular DirectX 9 game that was released in 2010. Though this game uses an old version of DirectX, the number of textures that can be represented on one screen can push most of the top-end graphics cards to their limits. StarCraft II: Wings of Liberty uses its own physics engine that is bound to the CPU and thus does not benefit from PhysX.

We tested this game at 1920x1200 and 2560x1600. The “Graphics Quality” was set to “Extreme” and the “Texture Quality” was set to “Ultra.” We then used FRAPS to collect the frame rate of a replay on the “Unit Testing” custom map. We used a battle between very large armies to stress the video cards.

Released in 2008, Far Cry 2 is based on a game engine called Dunia, which is DirectX 10. We used the benchmarking utility that comes with this game at 1920x1200 and 2560x1600, setting overall quality to “ultra high,” maximizing all image quality settings, adjusting anti-aliasing to “8x,” and running the “Ranch Long” demo three times. The results below are expressed in frames per second and are an arithmetic average of the three results collected.

Aliens vs. Predator

Aliens vs. Predator is a DirectX 11 game that makes full use of tessellation and advanced shadow rendering. We used the Aliens vs. Predator Benchmark Tool developed by Rebellion. This program reads its configuration from a text file. (Our configuration files can be found here.) We ran this program at 1920x1200 and 2560x1600, with texture set at “very high,” shadows set at “medium,” anisotropic filtering set at “8x,” and anti-aliasing set at “2x.”

Deus Ex: Human Revolution is another DirectX 11 game. We used the in-game introduction to measure the number of frames per second, using FRAPS. We ran the introduction in two resolutions, 1920x1200 and 2560x1536, maximizing all image quality settings, configuring anti-aliasing as “MLAA” and anisotropic filtering at “16x.”

Battlefield 3

Battlefield 3 is the latest installment in the Battlefield franchise released in 2011. It is based on the Frostbite 2 engine, which is DirectX 11. In order to measure performance using this game, we walked our way through the first half of the “Operation Swordbreaker” mission, measuring the number of frames per second using FRAPS. We ran this game at 1920x1200 and 2560x1536, maximizing all image quality settings, configuring anti-aliasing as “4xMSAA” and anisotropic filtering at “16x.”

3DMark 11 Professional

3DMark 11 Professional measures Shader 5.0 (i.e., DirectX 11) performance. We ran this program at 1920x1200 and 2560x1600, selecting the four graphics tests available and deselecting the other tests available. We used two image quality settings, “performance” and “extreme,” both at their default settings. The results being compared are the “GPU Score” achieved by each video card.

Media Espresso is a video conversion program that uses the graphics processing unit of the video card to speed up the conversion process. We converted a 449 MB, 1920x1080i, 18,884 kbps, MPEG2 video file to a smaller 640x360, H.264, .MPG4 file for viewing on a portable device such as an iPhone or iPod Touch.

Conclusions

In most games, the GeForce GTX 660 Ti was between 12% and 20% faster than its main competitor, the Radeon HD 7870 GHz Edition. There were some games in which both achieved the same performance, and on one, the GeForce GTX 660 Ti was 47% faster. There was no scenario where the GeForce GTX 660 Ti was slower than its competitor.

The GeForce GTX 660 Ti was between 7% and 49% faster than the GeForce GTX 560 Ti, and up to 32% faster than the GeForce GTX 570 (except on FarCry 2 at 2560x1600, where the GeForce GTX 570 was 11% faster than the GeForce GTX 660 Ti), which is found at the same price range.

Therefore, the GeForce GTX 660 Ti is, today, the best option if you have USD 300 to spend on a video card.

The SuperClocked version from EVGA was up to 6% faster than the standard GeForce GTX 660 Ti. Although the performance difference seems small, the price difference between the two models is only 3.33%, making it a savvy investment if you want to spend an additional USD 10 to get slightly higher performance.
