The NVIDIA GeForce GTX 1660 Ti Review, Feat. EVGA XC GAMING: Turing Sheds RTX for the Mainstream Marketby Ryan Smith & Nate Oh on February 22, 2019 9:00 AM EST
When NVIDIA put their plans for their consumer Turing video cards into motion, the company bet big, and in more ways than one. In the first sense, NVIDIA dedicated whole logical blocks to brand-new graphics and compute features – ray tracing and tensor core compute – and they would need to sell developers and consumers alike on the value of these features, something that is no easy task. In the second sense however, NVIDIA also bet big on GPU die size: these new features would take up a lot of space on the 12nm FinFET process they’d be using.
The end result is that all of the Turing chips we’ve seen thus far, from TU102 to TU106, are monsters in size; even TU106 is 445mm2, never mind the flagship TU102. And while the full economic consequences that go with that decision are NVIDIA’s to bear, for the first year or so of Turing’s life, all of that die space that is driving up NVIDIA’s costs isn’t going to contribute to improving NVIDIA’s performance in traditional games; it’s a value-added feature. Which is all workable for NVIDIA in the high-end market where they are unchallenged and can essentially dictate video card prices, but it’s another matter entirely once you start approaching the mid-range, where the AMD competition is alive and well.
Consequently, in preparing for their cheaper, sub-$300 Turing cards, NVIDIA had to make a decision: do they keep the RT and tensor cores in order to offer these features across the line – at a literal cost to both consumers and NVIDIA – or do they drop these features in order to make a leaner, more competitive chip? As it turns out, NVIDIA has opted for the latter, producing a new Turing GPU that is leaner and meaner than anything that’s come before it, but also very different from its predecessors for this reason.
That GPU is TU116, and it’s part of what will undoubtedly become a new sub-family of Turing GPUs for NVIDIA as the company starts rolling out Turing into the lower half of the video card market. Kicking things off in turn for this new GPU is NVIDIA’s latest video card, the GeForce GTX 1660 Ti. Launching today at $279, it’s destined to replace NVIDIA’s GTX 1060 6GB in the market and is NVIDIA’s new challenger for the mainstream video card market.

We’ll go into the full ramifications of what NVIDIA has (and hasn’t) taken out of TU116 on the next page, but at a high level it’s still every bit a Turing GPU, save the RTX functionality (RT and tensor cores). This means that it has the same core architecture in its SMs, and is directly comparable to the likes of the RTX 2060. Or to flip things around the other direction, versus the older Pascal and Maxwell-based video cards, it comes with all of Turing’s performance and efficiency benefits for traditional graphics workloads.
Compared to RTX 2060 then, the GTX 1660 Ti is actually rather similar. For this fully-enabled TU116 card, NVIDIA has dialed back on the number of SMs a bit, going from 30 to 24, and memory clockspeeds have dropped as well, from 14Gbps to 12Gbps. But past that, the two cards are closer in specifications than we might expect to see for a $70 price tag difference, especially as NVIDIA has kept the 6GB of GDDR6 on a 192-bit memory bus. In an added quirk, the GTX 1660 Ti actually has a slightly higher average boost clockspeed than the RTX 2060, with its 1770Mhz clockspeed giving it a 5% edge here.
The end result is that, on paper, the GTX 1660 Ti actually has a bit more ROP pixel pushing power than its bigger sibling thanks to that 5% boost clock advantage. However the drop in the SM count definitely hits compute and texture performance, where GTX 1660 Ti is going to deliver around 85% of RTX 2060’s compute and shading throughput. Or to frame things in reference to the GTX 1060 6GB it replaces, on the new card offers around 24% more compute/shader throughput (before taking architecture into account), a much smaller 4% increase in ROP throughput, and a very sizable 50% increase in memory bandwidth.
Speaking of memory bandwidth, NVIDIA’s continued use of a 192-bit memory bus in this segment continues to be a somewhat vexing choice since it leads to such odd memory amounts. I’ll fully admit I would have liked to have seen 8GB here, but then that was the case for RTX 2060 as well. The flip side being that at least they aren’t trying to ship a card with just a 128-bit memory bus, as was the case for GTX 960. This puts GTX 1660 Ti in an interesting spot in terms of memory bandwidth, since it’s benefitting from the jump to GDDR6; if you thought the GTX 1060 could use a little more memory bandwidth, GTX 1660 Ti gets it in spades. This has also allowed NVIDIA to opt for cheaper 12Gbps GDDR6 VRAM, marking the first time we’ve seen this in any video card.
Finally, taking a look at power consumption, we see that NVIDIA is going to be holding the line at 120W, which is the same TDP as the GTX 1060 6GB. This is notable because all of the other Turing cards to date have had higher TDPs than the cards they replace, leading to a broad case of generational TDP inflation. Of course we’ll see what actual power consumption is like in our testing, but right off the bat NVIDIA is setting up GTX 1660 Ti to be noticeably more power efficient than the RTX 20 series cards.
Wait, It's a GTX Card?
Along with the new TU11x family of GPUs, for this launch NVIDIA is also creating a new family of video cards: the GeForce GTX 16 series. With GTX 1660 Ti and its obligatory siblings lacking support for NVIDIA’s RTX family of features, the company has decided to clarify their product naming in only a way that NVIDIA can. The end result is that along with keeping the GTX prefix rather than RTX – since these parts obviously lack RTX functionality – the company is also giving them a lower series number. Overall it’s probably for the best that NVIDIA didn’t include these cards with the 20 series, least we get another GeForce 4 situation.
But on the flip side, the number “16” also doesn’t have any great meaning to it; other than not being “20” the number is somewhat arbitrary. According to NVIDIA, they essentially picked it because they wanted a number close to 20 to indicate that the new GPU is very close in functionality and performance to TU10x, and thus “16” instead of “11” or the like. Of course I’m not sure calling it the GTX 1660 Ti is doing anyone any favors when the next card up is the RTX 2060 (sans Ti), but there’s none the less a somewhat clear numerical progression here – and at least for the moment, one not based on memory capacity.
Price, Product Positioning, & The Competition
Moving on, unlike NVIDIA’s other Turing card launches up until now – and unlike the GTX 1060 6GB – the GTX 1660 Ti is not getting a reference card release. Instead this is a pure virtual launch, as NVIDIA calls it, meaning all the cards hitting the shelves are customized vendor cards. Traditionally these launches tend to be closer to semi-custom cards – partners tend to use NVIDIA’s internal reference board design or their first cards – so we’ll have to see what pops up over the coming weeks and months. For now then, this means we’re going to see a lot of single and dual-fan cards, similar to the kinds of designs used for a lot of the GTX 1060 cards and some of the RTX 2070 cards.
Another constant across the Turing family has been price inflation, and the GTX 1660 Ti is no exception. With a launch price of $279, the new card is launching at $30 above the GTX 1060 6GB it replaces. This is a lot better than the $349 that NVIDIA wants for the RTX 2060, but in case anyone thought that the $250 price tag of the GTX 1060 was a fluke, then it’s clear that sub-$300 is the new norm for xx60 cards, and not sub-$200 as the GTX 960 flirted with. It’s also worth noting that NVIDIA won’t be launching with any bundles here; neither the RTX Game On bundle nor the GTX 1060 Fortnite bundles will be in play here, so what you see is what you get.
In terms of positioning against their own cards, NVIDIA is rolling out the GTX 1660 Ti as the successor to the GTX 1060 6GB, the latter of which are becoming increasingly rare in the market as NVIDIA’s unplanned Pascal stockpile is finally drawn down. So the GTX 1660 Ti and GTX 1060 won’t be sharing space on store shelves for long. However like the other Turing cards, the GTX 1660 Ti is not a true generational successor to the GTX 1060; at roughly 36% faster, NVIDIA is not expecting anyone to upgrade from their mid-range Pascal card to this. Instead, NVIDIA’s marketing efforts are going to be heavily focused on enticing GTX 960 users, who are a further generation back, to finally upgrade. In that respect the GTX 1660 Ti has a very large performance advantage, but this may be a tough sell since the GTX 960 launched at a much cheaper $199 price point.
As for AMD, the launch of the GTX 1660 Ti finally puts a Turing card in competition with their Polaris cards, particularly the $279 Radeon RX 590, a fight that the Radeon cannot win. While AMD hasn’t announced any price changes for the RX 590 at this time, AMD will have little choice but to bring it down in price.
Instead, AMD’s competitor for the GTX 1660 Ti looks like it will be the Radeon RX Vega 56. The company sent word last night that they are continuing to work with partners to offer lower promotional prices on the card, including a single model that was available for $279, but as of press time has since sold out. Notably, AMD is asserting that this is not a price drop, so there’s an unusual bit of fence sitting here; the company may be waiting to see what actual, retail GTX 1660 Ti card prices end up like. So I’m not wholly convinced we’re going to see too many $279 Vega 56 cards, but we’ll see. If nothing else, AMD’s Raise the Game Bundle is being offered, giving them an edge over NVIDIA in terms of pack-in games.

Psycho_McCrazy - Tuesday, February 26, 2019 - linkGiven that 21:9 monitors are also making great inroads into the gamer's purchase lists, can benchmark resolutions also include 2560.1080p, 3440.1440p and (my wishlist) 3840.1600p benchies??
eddman - Tuesday, February 26, 2019 - link2560x1080, 3440x1440 and 3840x1600
That's how you right it, and the "p" should not be used when stating the full resolution, since it's only supposed to be used for denoting video format resolution.
P.S. using 1080p, etc. for display resolutions isn't technically correct either, but it's too late for that.
Ginpo236 - Tuesday, February 26, 2019 - linka 3-slot ITX-sized graphics card. What ITX case can support this? 0.
bajs11 - Tuesday, February 26, 2019 - linkWhy can't they just make a GTX 2080Ti with the same performance as RTX 2080Ti but without useless RT and dlss and charge something like 899 usd (still 100 bucks more than gtx 1080ti)?
i bet it will sell like hotcakes or at least better than their overpriced RTX2080ti
peevee - Tuesday, February 26, 2019 - linkDo I understand correctly that this thing does not have PCIe4?
CiccioB - Thursday, February 28, 2019 - linkNo, they have not a PCIe4 bus.
Do you think they should have?
Questor - Wednesday, February 27, 2019 - linkWhy do I feel like this was a panic plan in an attempt to bandage the bleed from RTX failure? No support at launch and months later still abysmal support on a non-game changing and insanely expensive technology.
I am not falling for it.
CiccioB - Thursday, February 28, 2019 - linkYes, a "panic plan" that required about 3 years to create the chips.
3 years ago they already know that they would have panicked at the RTX cards launch and so they made the RT-less chip as well. They didn't know that the RT could not be supported in performance with the low number of CUDA core low level cards have.
They didn't know that the concurrent would have played with the only weapon it was left to it to battle, that is prize as they could not think that the concurrent was not ready with a beefed up architecture capable of the sa functionalities.
So, yes, they panicked for sure. They were not prepared to anything of what is happening,
Korguz - Friday, March 1, 2019 - link" that required about 3 years to create the chips.
3 years ago they already know that they would have panicked at the RTX cards launch and so they made the RT-less chip as well. They didn't know that the RT could not be supported in performance with the low number of CUDA core low level cards have. "
and where did you read this ? you do understand, and realize... is IS possible to either disable, or remove parts of an IC with out having to spend " about 3 years " to create the product, right ? intel does it with their IGP in their cpus, amd did it back in the Phenom days with chips like the Phenom X4 and X3....
CiccioB - Tuesday, March 5, 2019 - linkSo they created a TU116, a completely new die without RT and Tensor Core, to reduce the size of the die and lose about 15% of performance with respect to the 2060 all in 3 months because they panicked?
You probably have no idea of what are the efforts to create a 280mm^2 new die.
Well, by this and your previous posts you don't have idea of what you are talking about at all.
