The GeForce GTX 1660 is the cut-down variant of the GTX 1660 Ti that Nvidia released earlier this year. It offers 2 less SMs for a total of 1408 CUDA cores compared to the 1660 Ti at 1563. The GTX 1660 also offers GDDR5 memory as opposed to its bigger brother’s GDDR6, ultimately lowering its price point at $219 USD.

Our card for this review is the ASUS GeForce GTX 1660 Phoenix OC Edition. A simple yet rather cute looking GTX 1660 with a single fan and a higher boost clock at 1850MHz. It is as basic as it looks with normal display options and features in tow.

PACKAGING AND ACCESSORIES:

The GeForce GTX 1660 Phoenix OC comes in your usual ASUS packaging. It’s a simple budget oriented colorbox, really. Nothing’s special about it.

The card comes with the usual documentations. I tired my best to look for more but this is just it.

DESIGN, LAYOUT AND BUILD QUALITY:

The ASUS GeForce GTX 1660 Phoenix OC is a dinky card. Styling is pretty much basic which is a nice contrast compared to their ROG offerings.

The back is devoid of any form of protection. Although to be fair, the exposed matte-Black PCB is a thing of beauty. The thing is also around 7 inches short, making itself an addition to the growing number of SFF system compatible cards.

Power on the other hand is provided by a single 8-pin connector with a matching pair of status LEDs at the top.

Cooling option is again rather basic. We have a single 90mm fan here on top of an aluminum heatsink. Though simple, the GDDR5 chips under the card are actively cooled as well. A nice touch from ASUS.

There are only 3 display options to choose from: A DisplayPort, an HDMI port and a single DVI-D port. In exchange, ASUS made sure that there is enough room for a proper ventilation.

FPS values are recorded by FRAPS in-game using a linear route or gameplay for consistency. The results includes the Average FPS and 1% Minimum FPS. The 1% Minimum FPS represents the negative spikes or drops in-game sufficient enough for a gamer to notice. If the game doesn’t support FRAPS, we will use the in-game benchmark tool available.

TEMPERATURE, POWER AND NOISE:

The graphics card thermal figures are taken during a 15 minute idle and a 15 minute load via the AIDA64 Extreme Edition Stability Test. The ambient temperature is checked at 27°C (±1°C), with values extracted via HWiNFO and GPU-Z.

Gaming performance wise, Nvidia made sure that the GTX 1660 is truly a faster card compared to the GTX 1060. That’s at least when it comes to the 1080P and 1440P benchmarks and with the exception of the older games on our list.

SOFTWARE, LIGHTING AND SPECIAL FEATURES:

The ASUS GeForce GTX 1660 Phoenix OC Edition comes with a number of bundled software. That includes the GPU Tweak II which is an all in one tuning and optimization solution.

The XSplit Gamecaster is also a part of the bundle too, with support for GPU Tweak II overlays. I am not sure how long you could use the license for this one though. WTFast and ASUS QuantumCloud also comes bundled with the card as well.

FINAL THOUGHTS:

The GTX 1660 in the form of the ASUS GeForce GTX 1660 Phoenix OC Edition is indeed a faster card compared to the GTX 1060. It managed to outpace the former midrange champion at both 1080P and 1440P but with a price point of $219 USD. That’s considerably low compared to the GTX 1060’s $300 USD MSRP upon its release. Power consumption is unfortunately also comparable but other than that, the card just darts where it should.

Product stacking wise, the GTX 1660 actually slots within the range of the GTX 1060 even after 2 years. That said, the card is not really geared towards the GTX 1060 owners but rather, built to appeal for those who have a former midrange champ like the GTX 970 and or an equivalent model.

As for this specific GTX 1660 model, ASUS managed to create something basic, yet appealing at the same time. We have a card that we could technically install on any system due to its tiny form factor. Plus, it had a proper gaming performance and a cooling solution that you would otherwise expect from a model with a beefier cooler.

  • STRONG 1080P PERFORMANCE
  • CAPABLE 1440P PERFORMANCE
  • CAPABLE COOLING SOLUTION
  • PRACTICALLY DEAD SILENT
  • DECENT PRICE POINT
  • SFF SYSTEM COMPATIBLE
  • POWER DRAW COMPARABLE TO GTX 1060
  • BUNDLE COULD BE BETTER
