Introduction
The GTX 1660 Super is no longer a “new GPU” conversation. In 2026, this card lives almost entirely in the used market, and that alone changes how you should judge it.
Despite its age, the 1660 Super still shows up in thousands of budget and mid-range gaming PCs. Why? Because it sits in a rare middle ground: noticeably stronger than entry-level GPUs, far more stable than older Polaris cards, and still efficient enough for everyday use.
Specifications
Below are only the specs that affect real-world performance.
| Spec | GTX 1660 Super |
|---|---|
| Architecture | Turing |
| CUDA Cores | 1408 |
| VRAM | 6GB GDDR6 |
| Memory Bus | 192-bit |
| Memory Bandwidth | 336 GB/s |
| PCIe Interface | PCIe 3.0 x16 |
| Base / Boost Clock | 1530 / 1785 MHz |
| TDP | 125 W |
| Power Connector | 1×8-pin |
| Launch Year | 2019 |
Two things immediately stand out:
- 6GB VRAM + wide memory bus still matter in 2026
- PCIe x16 means no platform-related performance loss on older systems
Gaming Performance
In esports titles, GTX 1660 Super maintains high average FPS with very stable frame pacing. This makes it a strong choice for competitive players who prioritize smooth gameplay over visual settings.
If you’re upgrading from entry-level GPUs like the GTX 1050 or even the GTX 1650, the performance jump is immediately noticeable, especially in minimum FPS and overall smoothness at 1080p.
AAA Games – 1080p Medium–High
While average FPS remains playable in modern AAA games, 1% lows reveal occasional dips during heavy scenes. This shows that this card can still handle newer titles, but with visible limits at higher settings.
1% Lows & Frame Consistency
Average FPS alone doesn’t tell the full story. This is where the GTX 1660 Super starts showing its age.
In newer AAA titles:
- Average FPS remains playable
- 1% lows drop into the mid-30s
What that means in real use:
- Minor stutter during heavy scenes
- Less consistent camera movement
- Noticeable dips during asset streaming
It’s still smoother than many older GPUs, but it’s no longer perfectly stable in modern engines.
Power Draw & Efficiency
Power consumption stays reasonable for a mid-range GPU, offering a good balance between performance and efficiency. While not as efficient as newer low-power cards, the GTX 1660 Super avoids the excessive heat and power draw seen on older GPUs.
Compared to RX 580:
- Lower power draw
- Less heat
- Better long-term reliability
Thermals & Noise (Used Card Reality)
On a healthy card with a clean cooler:
- Load gpu temperature: 65–72°C
- Fan noise: noticeable but not loud
Many used GTX 1660 Supers:
- Have worn fans
- Dried thermal paste
- Slight coil whine
Thermals depend more on card condition than model.
Driver Support & NVENC Advantage
In 2026, NVIDIA driver support for GTX 1660 Super is still solid.
But the real win here is NVENC.
If you:
- Stream casually
- Record gameplay
- Edit videos
GTX 1660 Super is far superior to RX 6400 in this area.
This makes it a strong budget-friendly option for content creators.

Buying a Used GTX 1660 Super
By 2026, the GTX 1660 Super mostly lives on the used market. Buying used can save you money, but a little care goes a long way.
First, check the condition. Look out for worn fans, dried thermal paste, or any coil whine, these small things can make a card feel older than it really is. A clean, well-kept card will last longer and perform better.
Next, think about stability under load. If you can, run a stress test to make sure the core clocks and VRAM are holding steady. Even if a card looks perfect on the outside, heavy use in the past can hide issues.
Finally, choose where you buy carefully. Trusted platforms like eBay or Amazon refurbished give some peace of mind, just check seller ratings and return policies before hitting buy.
A clean, tested GTX 1660 Super is still a solid pick in 2026. Take a few minutes to check condition and stability, and you can land a strong 1080p GPU without breaking the bank.
Who Should Buy GTX 1660 Super in 2026?
Good choice if you:
- Play esports regularly
- Want stable 1080p gaming
- Use older PCIe 3.0 systems
- Stream or record gameplay
- Buy used after testing properly
Avoid it if you:
- Want ultra settings
- Care about power efficiency above all
- Expect smooth future AAA performance
- Don’t want used hardware risk
Final Verdict
Still worth buying — conditionally.
GTX 1660 Super works in 2026 because it delivers balanced, predictable performance, not because it’s modern.
Quick takeaway:
- ✔ Strong 1080p esports performance
- ✔ Usable AAA gaming on medium settings
- ✔ Works perfectly on older PCIe 3.0 systems
- ✖ Not future-proof
- ✖ Depends heavily on used condition
Buy it if: you find a clean unit at the right price.
Skip it if: you expect ultra settings or long-term AAA headroom.
At the right price, it still earns its place.
