Overview

The EVGA GeForce GTX 1660 Super SC Ultra Gaming is a factory-overclocked 1080p-class GPU built on NVIDIA's Turing architecture (TU116 die). Its 1830 MHz boost clock sits above NVIDIA's reference 1785 MHz spec, and the 6GB GDDR6 frame buffer running at an effective 14 Gbps — versus the standard GTX 1660's GDDR5 — is the defining hardware advantage of the Super variant. That memory upgrade translates to roughly 32% more memory bandwidth than the non-Super 1660, which is measurable in bandwidth-bound scenarios at 1080p and gives the card meaningful extra runway at 1440p compared to its predecessor. The dual-fan cooler with zero-RPM idle mode handles the 125W TDP without stress, and the pre-installed all-metal backplate is a structural inclusion that many competing cards skip at this price tier.

This card is purpose-built for 1080p high-refresh-rate gaming — pairing it with a 144Hz 1080p monitor is its ideal use case, where it can sustain 60+ fps in demanding titles and push well above that in less GPU-intensive games. It's also a competent entry into 1440p at reduced settings. The lack of RT cores means ray tracing is off the table, but for players prioritizing raw rasterization performance per dollar at this performance tier, that's an acceptable trade-off. EVGA's build quality and warranty reputation make this a reliable long-cycle component for mid-range system builders who won't be upgrading for several years.

Pros & Cons

👍 Pros

  • Factory boost clock of 1830 MHz delivers measurable performance above reference GTX 1660 Super spec without any manual tuning.
  • 6GB GDDR6 at 14 Gbps effective speed provides strong 1080p bandwidth headroom for texture-heavy titles.
  • Dual-fan zero-RPM cooling keeps thermals controlled under load while remaining completely silent at idle.
  • All-metal backplate adds structural rigidity to the PCB and prevents GPU sag in horizontal builds.
  • Single 8-pin power connector requirement keeps compatibility broad — no modular PSU gymnastics needed.

👎 Cons

  • No hardware ray tracing support — this is a Turing-architecture card without RT cores, unlike the RTX 20-series siblings.
  • 6GB frame buffer becomes a constraint in 1440p gaming as texture budgets grow in newer titles.
  • DVI output is increasingly legacy — multi-monitor setups with modern displays will compete for the single HDMI and single DisplayPort connection.
  • The SC Ultra factory overclock, while real, is modest enough that it won't be perceptible in most frame-rate comparisons versus reference clocks.

Frequently Asked Questions

It uses a PCIe x16 slot and requires a single 8-pin power connector. Total board power is 125W, so any mid-range PSU (450W+) handles it comfortably.
At 1080p, 6GB is more than sufficient for virtually every current title. At 1440p, texture-heavy games can push toward the buffer ceiling — you may need to dial down texture quality in the most demanding games at that resolution.
The card offers DisplayPort, HDMI, and DVI outputs. Maximum supported resolution is 7680x4320 (8K), though gaming at that resolution is not within this card's performance envelope.
Yes. The SC Ultra's 1830 MHz boost clock is a factory overclock above NVIDIA's reference 1785 MHz spec — roughly a 2.5% uplift out of the box. EVGA's precision boost algorithm also allows further manual overclocking headroom via Precision X1.
The dual-fan cooler keeps temperatures well within spec under sustained load. Fans spin up audibly under full load but remain reasonable — they also stop entirely at idle and low loads, making the card silent during desktop use.
