Nvidia has launched its GeForce GTX 660 Ti graphics card, the fourth model based on the GK104 GPU. It's also the cheapest version to be based on the chip; with a price of around £230, the card is to compete with AMD's Radeon HD 7870 and HD 7950 models. Nvidia has equipped the card with 1344 shader units and a 192-bit memory interface. The clock frequencies are identical to those of the GTX 670, which, in some benchmarks, results in similar performance. On average, the GTX 660 Ti appears to be a lot faster than the Radeon HD 7870 and about as fast as an HD 7950 card with the new BIOS revision.
Nvidia has not created a reference design for the GTX 660 Ti, but because the chip is identical to the GTX 670 and 680 models, partners can just use a different PCB. For instance, they're able to create a cheaper version using the GTX 670 circuit board, or a more luxurious model based on a larger PCB with heavier power design. Some of Nvidia's partners have already announced their first versions of the card, the results of which are outlined below.
ASUS has introduced no less than five GTX 660 Ti graphics cards, all based on the DirectCU II principle. This means a luxurious PCB with an alternative cooler. The GTX 660 TI-DC2-2GD5 runs at Nvidia's reference clock frequencies (915 MHz core / 980 MHz boost / 6008 MHz GDDR5), With speeds of 967/1058/6008 MHz, the GTX660 TI-DC2O-2GD5 is overclocked slightly. The GTX660 TI-DC2T-2GD5 'TOP' version is clocked at 1059/1377/6008 MHz and the GTX660 TI-DC2O-2GD5 and GTX660 TI-DC2T-2GD5 are bundled with Steam coupons for Borderlands 2. All models have 2 GB of memory and 2x DVI, 1x HDMI and 1x DisplayPort video outputs. Support for Three-way SLI is also present.
Dutch partner Club3D has announced a single GTX 660 Ti, using the reference design of the GTX 670. This card has a smaller PCB with a dual-slot cooler extending from it by a few centimetres. The card has 2 GB of memory and operates at Nvidia's prescribed clock frequencies.
Colorful has unveiled an 'iGame' version of the GTX 660 Ti, equipped with an alternative cooler with twin 80 mm fans. Additional heatsinks are bundled with the card, which should keep the card chilled even better. No details are available on the card's clock frequencies. Colorful's creation will be available in both Asia and Europe.
EVGA has developed six GTX 660 Ti cards, three of which feature 3 GB of memory. The card's 192-bits memory interface allows for using chips of equal capacity. Apart from the 2 GB and 3 GB cards, a regular model, and overclocked SuperClocked and a FTW version with even higher clock frequencies have been announced. The SuperClocked version has a 980 MHz core clock, 1059 Mhz boost and 6008 MHz memory speed. The FTW model has a GPU base clock of 102 MHz, boost frequency of 1098 MHz and a 6008 MHz memory clock speed. The FTW edition is the only card with a longer PCB, required to fit its more powerful VRM design.
Gigabyte has planned two GTX 660 Ti cards, each equipped with the WindForce 2X cooler. These cards also have a slightly longer PCB and feature the traditional Gigabyte blue colours. While the two cards are identical in terms of hardware, one of the models runs at reference clock frequencies while the other has its core overclocked to 980 MHz, with a 1058 MHz boost frequency and 6008 MHz memory speed.
KFA will release two GTX 660 Ti models, both intended for an overclocking audience, as revealed by the large PCB with extra heatsinks and the cooler with two fans. Both models are overclocked out of the box too, with a 1006 MHz core clock and 1084 MHz Turbo boost. While the memory frequencies remain untouched, one of the cards has had an upgrade to 3 GB of GDDR5, rather than 2 GB. The two KFA GTX 660 Ti's offer DisplayPort, HDMI and 2x DVI. A notable detail are the pulsating LEDs that have been incorporated in the heatsink.
MSI comes with two 'Power Edition' graphics cards, the overclocked N660Ti PE 2GD5/OC and the reference N660Ti PE 2GD5. These cards both have an alternative cooler with twin fans, resulting in a 14 degrees Celsius temperature decrease, as well as a 17.1 dB(A) drop in sound production, MSI claims. The overclocking potential is allegedly exactly 18.2% higher, thanks to the improved power design and the 'Frozr IV Thermal Design'. The heatsink has been equipped with a number of heatpipes, two of which are 8 mm thick. The cards use Tantalum Core Hi-c CAP and solid-cap capacitors, which should improve the card's durability.
Point of View
Like Club3D, Point of View will also feature just one GTX 660 Ti card, based on the reference design of the GTX 670. This means that the card will have the same standard dual-slot cooler, which blows the heat directly out of the chassis. The clock frequencies are also untouched, meaning 915 MHz for the core, 980 MHz Boost and 6008 MHz for the GDDR5 memory.
PNY is the third brand to introduce a single GTX 660 Ti, again based on the reference design of a GTX 670 card. With stock clock frequencies, the card should mostly appeal through its $299 pricetag. PNY's card comes with a 3-month subscription to the ESEA Premium Video Game Network. The card has a single year of factory warranty, which is extended when the card is registered. A 24-hour helpdesk is also part of PNY's service.
The final Nvidia partner to show off its new creations is Zotac, which has two GTX 660 Ti cards in the works. Both models are overclocked, with the regular version having a 928 Hz core clock and 6608 MHz memory speed. The AMP! edition kicks it up a notch, by increasing the core clock frequency to 1033 MHz. Like most models, these two cards have an alternative cooler with several heatpipes.
