The ASUS Dual GeForce GTX 1660 Super OC 6GB EVO (model DUAL-GTX1660S-O6G-EVO) is a graphics card for desktop PCs. It is built on NVIDIA's Turing architecture and pairs a factory overclock with two cooling fans. It is a card for gaming at 1080p and for adding display outputs to a desktop. Here is what its specifications mean.
NVIDIA Turing, CUDA cores and memory
The card has 1408 CUDA cores, the small parallel processors that do the graphics work, and 6GB of GDDR6 memory on a 192-bit interface, with a listed memory clock of 14002 MHz. The memory size matters for texture detail: 6GB is typically enough for many games at 1080p, while newer titles at higher settings may ask for more. The wider the memory interface and the faster the clock, the more data the card can move each second.
ASUS describes the card as overclocked, meaning the factory clock speeds are set above NVIDIA's reference figures. The listing does not give the exact clocks, so check ASUS's product page if you need them.
Dual-fan cooling
The card uses two Axial-Tech fans in a shroud designed to match ASUS motherboards. ASUS says the dual-fan design doubles airflow and delivers "3x quieter gameplay" compared with its reference cooling, a comparison that depends on how ASUS measured it. In general, larger fans can spin more slowly for the same airflow, which tends to reduce noise.
Size: a 2.7-slot card
ASUS lists the card as 2.7 slots thick, and the listing dimensions are about 9.5 x 5.1 x 2.1 inches (24 x 13 x 5 cm). A card this thick takes up the neighbouring expansion slots in the case, so check the clearance on your motherboard and case.
Display outputs
The card has HDMI 2.0B, DisplayPort 1.4 and DVI-D ports and supports up to three monitors. The DVI-D port is handy if you have an older monitor, and the HDMI and DisplayPort outputs cover modern displays and TVs.
Software and components
GPU Tweak II is ASUS's utility for monitoring the card and adjusting its settings, and the listing says it is supplied with extra software such as Game Booster, XSplit Gamecaster, WTFast and quantumcloud. ASUS also says that Auto-Extreme manufacturing and Super Alloy Power II components make the card run "15% faster and last 2.5 longer than reference video cards". These are brand claims measured against ASUS's own baseline. The listing also describes the card as VR ready.
Who it suits
It suits desktop builders and upgraders who want a 1080p gaming card with a quiet cooler and flexible outputs. It is not designed for the latest ray-traced titles, since Turing's GTX 16-series cards lack the dedicated ray-tracing hardware of NVIDIA's RTX cards.
What to check before you buy
- Case space: measure the available length and the width of two and a half or more slots.
- Power supply: check the card's power connector and the recommended power supply wattage in ASUS's specifications.
- Motherboard slot: it fits a PCI Express x16 slot; check your motherboard's free slot.
- Monitor inputs: match your monitors to the HDMI, DisplayPort and DVI-D outputs.
- Drivers and software: download current drivers from NVIDIA and check which extra software you want to install.
- Processor pairing: an older or low-end processor may limit performance.
