GTX 1660 vs. GTX 1660 Super vs. GTX 1660 Ti vs. RTX 2060

Nvidia’s midrange graphics lineup is far more robust in 2020 than it was this time last year, with a much broader array of options for gamers on a budget. Being spoiled for choice does have its own drawbacks though, namely that picking the right graphics card for you is much harder.

To see how these cards stack up against one another, we’ve pitted the GTX 1660 against the GTX 1660 Super, GTX 1660 Ti, and the RTX 2060, comparing their specs and features. Which will offer the most bang for the buck?

Availability and pricing

All four of the cards we’re comparing are available for purchase right now and in a staggering array of options. The RTX 2060 is the most straightforward of the three with Nvidia’s Founders Edition acting as a firm baseline. When in stock it starts at $300 for the KO edition, while overclocked cards or those with fancy cooling solutions can cost up to $370

There are no Founders Editions for the GTX 1660 Ti and 1660 Super, but those cards debuted with a bewildering number of third-party alternatives. The former sells for between $280 and $320, while the latter starts at $230, with the most expensive versions priced at around $270. The standard 1660 is the most affordable with a starting price of $220, but as you’ll see below, that’s a hard sell considering how far it falls behind the competitively priced Super version.

There are tons to choose from when it comes to all of these Turing cards, offering different clock speeds, cooling options, and lighting features. Some are a better value than others, but the cheapest offer the best return on investment in terms of performance, as we’ll see below.

Performance

Nvidia has made a concerted effort to stagger its graphics card performance and the RTX 2060, GTX 1660 Ti, and 1660 occupy distinct price and performance brackets. A look at their raw specifications betrays the real-world performance of these cards as much almost as benchmarks have been able to do.

Memory Bandwidth 336GBps 288 GBps 336GBps 192GBps
TDP 160w 120w 125w 120w

Based on the specifications alone we can surmise that the most powerful of the three cards is the RTX 2060, followed by the GTX 1660 Ti, then GTX 1660 Super, with the GTX 1660 trailing in the rear. The steps from each card are a little different, however. While clock speeds are relatively comparable across all four cards (and actually a little higher on the lower-end cards), the drop in CUDA cores from the RTX 2060 to the 1660 Ti is the main differentiating factor in performance. While the 1660 does take a step down in CUDA cores too, its use of GDDR5 memory leads to a 33 percent reduction in memory bandwidth.

That’s also where the GTX 1660 Super makes up its lower CUDA core count. With faster memory, it is much closer in performance to the 1660 Ti than its other specifications might suggest.

These differences play out like you might expect in games, although there is some variation depending on your desired quality settings and resolution. In all tests the RTX 2060 comes out well ahead of its GTX Turing counterparts, offering performance comparable to a GTX 1070 Ti, if not sometimes higher. The 1660 Ti follows up with between 15 and 25 percent lower frame rates, though it does beat important AMD competitors like the RX 590. It even poses a real challenge to the Vega 56 in some cases.

The GTX 1660 Super is typically within only a few frames per second of the 1660 Ti, making it arguably the most competitive buy among the 1660s. Especially since its price is so close to that of the stock 1660.

The GTX 1660 has a strong showing against a number of cards, providing a 10-20 percent improvement over the GTX 1060 6GB in most cases. It too challenges or exceeds the RX 590 and 580 in a number of games at both 1080p and 1440p, but falls behind the 1660 Ti by between 10 and 25 percent depending on the game being tested.

Ray tracing and DLSS

Metro Exodus Review

Although the RTX 2060 has hardware-accelerated ray tracing support, the other cards do support it too, albeit in a limited capacity. Thanks to a driver update from Nvidia, all GTX cards from the 16 and 10-series can render ray tracing in-game, but without hardware acceleration using RT cores, performance isn’t great, even on high-end last-gen cards like the GTX 1080 Ti.

The difficulty with ray-traced lighting effects is that they are exceedingly GPU intensive to render. That’s why the RT cores are required and make such a difference on RTX cards; especially the higher-end ones. If you want to play ray traced games at comfortable frame rates, the RTX 2060 is the only card to opt for in this case, though it will still be limited to 1080p in most games. The GTX 16-series cards will let you get a look at what ray tracing looks like, but they won’t be able to play many ray-traced games at anything close to comfortable frame rates.

With that in mind, it’s unfortunate that deep learning super sampling support (DLSS) is restricted to RTX graphics cards. It requires Tensor cores to run and the GTX 1660, 1660 Super, and 1660 Ti just don’t have them, so they will not be able to use DLSS. The RTX 2060 can, and that could give it a further advantage when it comes to ray tracing, although the highly limited number of supported games right now makes it somewhat negligible. Furthermore, our experience of both features combined hasn’t been stellar so far.

You get what you pay for

GTX 1660 Super

If $300 – $350 is too high of a price tag for you, then the GTX 1660 Super is the best value option of the bunch. The 1660 Ti is only worthwhile if you can find it at a comparable cost. Performance is so close between the two cards that the Super, with its typical $50 to $100 savings, is a better buy. It almost invalidates the RX 590 from AMD, although we see some heavily discounted RX 590s, making it an attractive alternative.

The GTX 1660 is far harder to recommend, however. While it is certainly a better buy than a last-generation GTX 1060, competition is considerably stiffer from AMD at this price point. The RX 580 and RX 590 are both viable alternatives. In some cases, they can be cheaper, especially when you factor in AMD’s game bundles. Here’s where availability and packaging can make or break a deal. Packages are almost always a smarter option than standalone cards. Availability (and retailer sales) can also factor into the equation. The more recent RX 5500 XT is nearly as quick, too, and at a lower price. We certainly wouldn’t suggest buying the factor overclocked versions, though. The price difference between those and the 1660 Super is too close to make them worth it.

Overall, the RTX 2060 is the best buy of the three because of its performance capacity. It’s still not a cheap card, so it’s not our top choice as far as budgets go. Still, it gives much more value for the money than its lower-end Turing counterparts. Over time, it’s worth the investment for the RTX 2060 — even if you have to save up to buy it.
