When Nvidia launched the GTX 1660 Super in October 2019, few expected it to anchor budget PC builds for the better part of a decade. Wedged between the standard 1660 and the pricier 1660 Ti, it swapped slow GDDR5 memory for brisk 14 Gbps GDDR6. That single tweak unlocked massive memory bandwidth and turned a modest mid-range card into an enduring icon. Years after Nvidia ceased production, this card remains a staple of the secondhand market. It defines the entry-level 1080p gaming experience for anyone shopping on a tight budget.
If you're hunting for a cheap used graphics card or trying to extend the life of an aging desktop, understanding this card's real-world limits matters. It doesn't support ray tracing, it lacks DLSS, and its 6GB VRAM buffer faces strict ceilings in modern blockbusters. Yet, for esports titles, older AAA games, and everyday productivity rigs, it punches well above its weight class.
Architectural Roots and the GDDR6 Advantage
To see why this card outlived its product cycle, look under the hood. It runs on Nvidia's Turing architecture, utilizing the TU116 silicon chip. Crucially, Nvidia omitted dedicated RT cores and Tensor cores from this die. That choice kept manufacturing costs low and power consumption modest at a 125W TDP.
The defining upgrade over the base 1660 was the memory subsystem. By shifting to 6GB of GDDR6 running across a 192-bit bus, memory bandwidth jumped from 192 GB/s to 336 GB/s. That seventy-five percent increase removed the bottleneck plaguing the original card. It allowed the GPU core to feed data fast enough to maintain stable frame rates where lesser cards stuttered.
- CUDA Cores: 1408
- Base Clock: 1530 MHz
- Boost Clock: 1785 MHz
- VRAM: 6GB GDDR6 at 14 Gbps
- Bus Interface: PCIe 3.0 x16
Real-World 1080p Gaming Performance
At 1080p resolution, this GPU finds its true calling. It handles competitive esports titles with ease. Games like Valorant, Counter-Strike 2, Apex Legends, and Fortnite easily clear high frame rate thresholds on medium-to-high settings, satisfying monitors with fast refresh rates.
Heavier single-player titles require more careful tuning. In games built between 2018 and 2022, you can expect smooth 60 FPS averages on high settings. However, modern releases featuring heavy ray tracing demands or unoptimized asset streaming will force you down to medium settings. Because the card lacks Tensor cores, you can't turn on Nvidia DLSS to recover lost frames. You must rely on native resolution or AMD's open-source FSR 2, which helps bridge the gap in supported software.
The VRAM Constraint in Modern Titles
The most pressing limitation today is the 6GB frame buffer. Modern game engines aggressively stream high-resolution textures that easily overflow 6傑 limits at ultra settings. When VRAM fills up, cards suffer severe stuttering as data swaps over system memory.
To keep this card viable, you must manage texture quality sliders downwards. Doing so keeps video memory usage safely below the threshold, preserving smooth frame delivery even in recent titles.
System Pairing and Power Requirements
One major advantage of buying or keeping this hardware is its low system overhead. Because it draws 125 watts, it doesn't require an expensive power supply upgrade. A reliable 450W to 500W PSU handles a system powered by this card without breaking a sweat.
- Power Supply: Minimum 450W recommended, with a single 8-pin PCIe power connector.
- Motherboard Compatibility: Uses PCIe 3.0, but drops smoothly into PCIe 4.0 or 5.0 slots with negligible performance loss.
- CPU Pairing: Don't pair this with bleeding-edge processors like an AMD Ryzen 9 or high-end Intel Core i7. Match it with budget chips like an Intel Core i3-12100F or AMD Ryzen 5 3600 to avoid severe budget imbalance.

Encoder Quality for Budget Creators
Beyond gaming, this GPU gained a second life among budget streamers and video editors. It features the Turing NVENC encoder, which matches the hardware encoding quality found in the RTX 20-series.
For creators on a budget, streaming gameplay via OBS Studio using the Nvidia NVENC encoder shifts the workload off the central processor. This results in clean, dropped-frame-free streams at 1080p without tanking your game's performance. It also accelerates video exports in software like Premiere Pro and DaVinci Resolve, making it a surprisingly capable engine for entry-level content creation workstations.
Buying Used: What to Watch For
Since retail stock vanished long ago, finding one means shopping the secondhand market. Prices typically hover well below modern entry-level cards, making it an attractive proposition for ultra-budget builds. However, buying used hardware requires caution.
- Check Fan Bearings: Listen for rattling or grinding noises. Budget dual-fan models often wear out after years of continuous spinning.
- Verify Thermals: Run a benchmark like FurMark and ensure temperatures stay under 80 degrees Celsius under full load. High temps indicate dried-out thermal paste.
- Avoid Ex-Mining Cards: While mining units aren't automatically dead, cards run continuously in poorly ventilated rooms often suffer from degraded fan motors and memory heat stress.

Frequently Asked Questions
Can this card run games at 1440p?
It can output a 1440p signal, but gaming performance at that resolution is generally poor unless you play older or highly optimized esports titles. Modern games will choke on both the core processing power and the 6GB VRAM limit at 1440p.
Does it support Windows 11?
Yes. Nvidia continues to issue standard Game Ready and Studio drivers that maintain full compatibility with Windows 11 for the entire Turing GTX 16-series family.
How does it compare to the AMD Radeon RX 6600?
The AMD RX 6600 generally outperforms the 1660 Super by a noticeable margin while offering 8GB of VRAM. If you find both cards at similar prices on the used market, the RX 6600 is the superior buy. The 1660 Super only makes sense if it is significantly cheaper.
Is ray tracing usable on this card?
Technically, Nvidia enabled software-level ray tracing support via driver updates for the GTX series. Practically, the hardware lacks dedicated RT cores, meaning turning ray tracing on causes frame rates to plummet to unplayable single-digit levels. Leave it turned off.
