The NVIDIA GeForce GTX 1660 Review, Feat. EVGA XC GAMING: Turing Stakes Its Claim at $219by Ryan Smith & Nate Oh on March 14, 2019 9:01 AM EST
As NVIDIA’s carefully orchestrated rollout of its Turing family of GPUs and related video cards keeps steaming right along, we’re back again this month with the next piece in the GeForce product stack. Last month was, of course, the GeForce GTX 1660 Ti; and if you know anything about NVIDIA naming then you know that NVIDIA never does a stand-alone Ti card. As a suffix indicating higher performance, if there’s a Ti card, then there needs to be a regular card as well. And today NVIDIA is delivering on just that with the vanilla GeForce GTX 1660.
For the Turing family launch, NVIDIA has been following a very straightforward top-to-bottom video card launch, and today’s GeForce GTX 1660 launch continues that pattern. With the GTX 1660 Ti coming in at the very top end of the mainstream market with a $279 price tag, NVIDIA is now ready to launch its lower-tier, more wallet-friendly $219 counterpart. This continues NVDIA’s cascade of Turing video cards down to lower prices and lower performance levels, raising the bar for video card performance at each price tier.
Turning our eyes to NVIDIA’s new card then, within the NVIDIA Turing GeForce product stack the GTX 1660 is essentially a cut-down GTX 1660 Ti, and serves as this generation’s version of the GeForce GTX 1060 3GB. Which is to say that it’s a card that uses the same GPU in a slightly cut-down configuration – in this case the same TU116 introduced for the GTX 1660 Ti – while instead making a larger tradeoff in memory in order to bring the price of the card down. Gone is GDDR6 in favor of cheaper, more widely available GDDR5, and better still you get a full 6GB of it.
Equally as important however, NVIDIA has (largely) stopped the naming shenanigans for this generation by not using memory capacity to indicate overall GPU performance. Though I’m still not a fan of suffixes (as they tend to get unintentionally cut off), this situation is massively better than the GTX 1060 naming system. So I will give credit to NVIDIA for not making the same consumer-unfriendly decision twice in a row.
Setting up today’s launch then, from a consumer standpoint the GTX 1660 may very well be the most important NVIDIA video card launch of the year. As what’s essentially NVIDIA’s $200 video card – with NVIDIA cheekily tacking another $20 on it – we’re now getting into NVIDIA’s high-volume desktop products. It’s mainstream cards like these that make up the biggest chunk of NVIDIA’s desktop shipments, so this is the card that’s going to be setting the pace for the mainstream market for the world-over. But first, let’s see if it’s any good.

Diving into the GeForce GTX 1660’s specifications, what we find is a very familiar echo of the GTX 1660 Ti. NVIDIA is of course using the same TU116 GPU as before, making the GTX 1660 the company’s second-tier TU116 card. However rather than a fully-enabled GPU, the TU116 is slightly cut-down, shaving off 2 of the GPU’s 24 SMs, leaving 22 enabled for a total of 1408 CUDA cores.
Otherwise there are no other changes on the GPU front; in particular all of the ROPs are enabled, and clockspeeds have actually gone up just a tad, with the official boost clock rated for 1785MHz. So unlike NVIDIA’s higher-performance products where the steps in GPU configurations are much larger, the GTX 1660 family keeps things close, giving NVIDIA an avenue for salvaging chips but not creating a wide gap between them. As a result, on paper the GTX 1660 has 92% of its bigger sibling’s shading/texturing/geometry throughput, and 101% of its ROP throughput. But don’t let that fool you; how TU116 has been cut-down plays second-fiddle to the memory changes.
As I mentioned at the start of this article, like the GTX 1060 3GB before it, NVIDIA’s defining change for this card isn’t the GPU, but rather the memory. For the GTX 1060 3GB that change was tossing out half the memory, resulting in a 3GB GDDR5 card that to this day I still think was a short-sighted decision. Thankfully, for the GTX 1660 vanilla, NVIDIA is doing something different: swapping out cutting-edge GDDR6 for the tried and true backbone of the video card industry that is GDDR5. GDDR5 of course isn’t as fast as GDDR6 – and critically, this is where GTX 1660 loses a lot of its performance versus GTX 1660 Ti – but it still delivers a good amount of memory bandwidth. And better still, it means NVIDIA is shipping the card with a more appropriate 6GB of VRAM.
By the numbers then, the GTX 1660 ships with 6GB of GDDR5, which is attached via a 192-bit memory bus and operating at 8Gbps. As it so happens, this means that the GTX 1660 has exactly the same amount of memory bandwidth as the GeForce GTX 1060 6GB and 3GB; so on a generational basis, NVIDIA needs to get more performance out of the same amount of memory bandwidth.
Or, to put things within the context of the Turing generation, this is only 2/3rds the data rate of GTX 1660 Ti’s 12Gbps GDDR6, so the aggregate bandwidth reduction is significant, dropping from 288GB/sec to 192GB/sec. However as we’ll see here for the GTX 1660 – and as we’ve seen before with other video cards that ship with multiple memory speeds – video card performance scaling is far less than 1-to-1 with memory speeds. So while this causes the GTX 1660 to fall behind the GTX 1660 Ti by a decent gap, TU116 isn’t completely hamstrung by GDDR5.
Finally, to draw one last parallel to the GTX 1060 3GB, like its predecessor NVIDIA is targeting the same 120W TDP. The GTX 1060 cards all shipped with the same TDP, as it will be for the GTX 1660 cards as well. The net result is that the vanilla GTX 1660 is essentially a bit less power efficient than its Ti sibling, delivering less performance for the same power consumption. And while NVIDIA’s TDP choice is functionally arbitrary, this gives the company an outlet for marginal TU116 chips that are a little more hooked on the juice (the best chips, of course, going into laptops). The upshot is that because the GTX 1660 has fewer SMs vying for power, it means that it can boost just a bit higher, giving the card higher average clockspeeds. This also helps to keep the two GTX 1660 cards a bit closer in performance than the specs would otherwise indicate – at least when the vanilla GTX 1660 isn’t memory-bandwidth bound.
Price, Product Positioning, & The Competition
In the Pascal generation, the GTX 1060 3GB was NVIDIA’s $199 “sweet spot” video card. However like the rest of the new Turing generation, the GTX 1660 is subject to price inflation. The GTX 1660 Ti came in at $279 – which was $30 higher than before – and similarly the GTX 1660 is getting a $20 price bump to $219. This means that although NVIDIA isn’t quite hitting the sweet spot, the GTX 1660 is essentially their take on a $200 video card.
Like last month’s GTX 1660 Ti launch, today’s GTX 1660 launch is a pure virtual launch for NVIDIA and its board partners. meaning that NVIDIA is not doing any kind of retail reference card here, and all the cards hitting the shelves are customized vendor cards. In practice, expect most (if not all) of these cards to look like the GTX 1660 Ti cards that just hit the market; with the same GPU running at the same TDP, it’s quick and efficient for board vendors to reuse their designs, even with the change in memory types. TU116 is of course pin-compatible with itself, though I’m not yet sure if GDDR6 and GDDR5 can use the exact same PCBs, as the new memory has a different pin count.
NVIDIA is calling today’s launch a hard launch, though truth be told I’m not convinced it will be quite as hard of a launch as last month’s GTX 1660 Ti. We actually had to go through a few board partners before we were able to secure a sample, as other board vendors didn’t have samples available (thanks, EVGA!). So I get the distinct impression that local offices and distributors were cutting it rather close on receiving their cards ahead of today’s launch date. At any rate, by the time this article goes live, we should have a better idea of just how well-stocked this launch is.
Looking at the product stacks, within NVIDIA’s product stack this card is set to replace the GTX 1060 3GB, with the earlier GTX 1660 Ti having done the same to the GTX 1060 6GB. In practice the channel has been mostly depleted of GTX 1060 6GB cards anyhow, but whatever cards remain have just been rendered obsolete for retail purposes, as the GTX 1660 is all-around better for the same price or less. Meanwhile the remaining GTX 1060 3GB cards – which were largely under $200 to begin with – will soon face the same fate.
Otherwise, NVIDIA is once again playing this launch straight in terms of bundles. There will be no game bundles for any of the GTX 1660 series, so the value of the product is the value of the video card itself. The outgoing GTX 1060 cards on the other hand do qualify for NVIDIA’s Fortnite bundle, though it goes without saying that Fortnite is a free game to begin with.
Meanwhile in terms of intended market, like the GTX 1660 Ti before it, NVIDIA is targeting the vanilla GTX 1660 at the mainstream market, and is particularly pitching it as an upgrade from the GTX 960, GTX 760, R9 380, and other ~$200 mainstream video cards from earlier this decade. Turing cards haven’t been a true generational upgrade over their Pascal predecessors, and GTX 1660 is no different; the new card is about 28% faster than the GTX 1060 3GB it replaces.
As for NVIDIA’s loyal opposition, the launch of the GTX 1660 will continue to put pressure on AMD’s aging Polaris video cards. The GTX 1660 is faster than all of them – including the fastest RX 590 – so AMD and its board partners will have little choice but to cut prices. This means AMD can try to position their cards as spoilers to the GTX 1660 – and $219 RX 590 cards are already popping up – but they can’t take on NVIDIA in terms of performance or power efficiency. AMD will have an edge in pack-in bundles though, as they’re continuing to offer their Raise the Game Bundle, which for the RX 590 is the full, 3 game pack.

Flunk - Thursday, March 14, 2019 - linkAnd about 4 years of time. That's not a very good deal.
flyingpants265 - Thursday, March 14, 2019 - linkWhile you're at it, can you make Bench compare multiple cards at the same time? This site seems oddly trapped in 2007 in some ways.
catavalon21 - Friday, March 15, 2019 - linkOr, it ties or bests the GTX 980 in 43 of 44 benchmarks. Not bad for a $219 card with a 3 year warranty (compared to whatever life one will get out of a 980 after years of mining...)
maroon1 - Thursday, March 14, 2019 - linkJust buy GTX 1660 Ti
flyingpants265 - Thursday, March 14, 2019 - linkJust spend more money
brunis.dk - Friday, March 15, 2019 - linkJust dont be homeless!
TallestJon96 - Friday, March 15, 2019 - linkJust buy RTX 2080 TI
0ldman79 - Thursday, March 14, 2019 - linkI was thinking the same.
I tripped over a deal for 970 SLI, makes the 1660 even less appealing. 970 vs 1660 looks like the difference between high and ultra at 1440p or something, hardly worth $200.
Not yet, Nvidia...
celtiberian - Saturday, March 16, 2019 - linkI have a GTX 970 running full HD. I don't really need to upgrade now unless I plan to run higher resolutions or a VR set.
With the CPU race, a CPU upgrade is more likely after zen 2 is released (still running the old reliable i5 2500k OC).
just4U - Sunday, March 17, 2019 - linkEvery once in awhile I am on 2600K setups.. and can certainly see they are showing their age now.
