ZOTAC GTX 1660 Ti Amp Edition Graphics Card Review

“Turing without Ray Tracing” is the motto of NVIDIA’s TU116 GPU, aiming at the balance performance, power, and cost at the same time in an effort to bring to the 1080p gamers the new graphics card that allows them to have an upgrade path – more specifically the users of the GTX 960 and GTX 1060 graphics cards.

TU116 includes all of the new Turing Shader innovations that improve performance and efficiency, including support for Concurrent Floating Point and Integer Operations, a Unified Cache Architecture with a larger L1 cache, and Adaptive Shading. The new graphics cards in this segment are GeForce GTX 1660 and 1660 Ti.

Surprised! GTX! Really! What NVIDIA has been thinking! Welp, to sum it all up, they are using the GTX nomenclature because they have dropped the RT and Tensor Cores from this GPU altogether in an attempt to bring the efficient graphics solution under the $300 range.

Both GeForce GTX 1660 Ti and 1660 GPUs are based on NVIDIA’s “TU116” GPU. TU116 has been tailored for efficiency. At the heart of the TU116 GPU lies a new SM. NVIDIA engineers have equipped this unit with dedicated cores for processing FP32 and integer operations simultaneously, FP16 processing at double the rate of FP32 operations, and have also updated the CUDA Cores to take advantage of the latest advancements in programmable shading.

Like other Turing GPUs, the TU116 SM also features enhanced caches that are more configurable, offer more capacity, and deliver improved bandwidth. Ultimately, as a result of these changes, the TU116 SM offers a dramatic improvement over the prior generation GP106 Pascal SM used in GeForce GTX 1060. The below table shows the comparison of the Pascal-based GeForce GTX 1060 6GB and 3GB and Turing-based GeForce GTX 1660 Ti and GeForce GTX 1660.

Salient features of the TU116 are:

• Concurrent FP and INT Processing
• Variable Shade Rating
• Unified Cache Architecture
• Fast GDDR6 Memory
• Dedicated FP16 Cores
• Enhanced NVENC Coder

The ZOTAC GeForce GTX 1660 Ti packs 1536 CUDA Cores with a base clock of 1500MHz and a boost clock of 1860MHz. It features 6GB VRAM GDDR6 rated at 12 Gbps having a bus width of 192-bit using 288 GB/s bandwidth. The graphics card has 3x Display Ports and 1x HDMI port.

It features ZOTAC’s Icestorm 2.0 cooling solution using 2x 90mm fans and an aluminum-based heatsink wide array with 3x nickel-plated copper heat pipes, each of 6mm thickness. The graphics card has an aggressive, bold, and beautifully designed shroud which sits that well with the wrap-around metallic backplate. There is no LED lighting on this card.

Closer Look

It is time to take a closer look at the ZOTAC GeForce GTX 1660 Ti Amp Edition. The dimension of the graphics card is 209.6mmX119.3mmX41mm (LxHxW). This is dual slot design. This is a factory overclocked card using a custom PCB. It is based on TU116 GPU from NVIDIA using 12nm technology with a die size of 284 mm² and packs 6600M transistors.

It has 48 ROP and 96 TMU units with 1536 CUDA Cores or shader units. The pixel fill rate is 89.3 GPixel/s and texture fill rate is 178.6 GTexture/s. This card has 6 GB from Micron using GDDR6 with a bus width of 192-bit and cap at 288 GB/s bandwidth. The base clock on this card is 1500MHz with a boost clock of 1860MHz. The card is designed to fit in over 90% of the systems with a focus on the compact design.

The really cool thing about the ZOTAC GeForce GTX 1660 Ti is its design. I am absolutely in love with this design. The wrap around the idea is what I have been looking for in the cards and ZOTAC was thankfully ahead of the thinking in using the combination of plastic and metal without losing the overall aesthetics yet reducing the weight of the card given the toll it can take on the motherboard’s PCIe slots.

The shroud mimics the ZOTAC’s brand logo in an aggressive and bold manner. The outcome is one heck of a beautifully designed shroud finished in a gray color with black color fans blades complimenting the looks. The top and the bottom sides of the shroud itself are identical.

Same goes for the left and right sides with an exception that the left side has two cutouts on the top and bottom which are probably for the ventilation. The center has stepped design with a mere focus on the central portion which is tipped out. Either you start traversing from the bottom to the center or from the top to the center, it is alike.

Cooling Solution

The cooling solution on the ZOTAC GeForce GTX 1660 Ti is named as IceStorm 2.0 and it is nothing new design with potent cooling potential. Let’s take a look at the ingredients of this cooling solution.

The ZOTAC GeForce GTX 1660 Ti features 2x 90mm fans which are designed for optimal static pressure and maximum airflow. This card does not have Auto Fan stop as we have been seeing on many recent models.

The blades of the fans are designed such that they have a gap in between each other to maximize airflow.

The main component of the cooling solution is the wide arrange aluminum heatsink. This full body heatsink allows for the maximum heat dissipation. There are two nickel plated copper plates making direct contact with the GPU, VRAM chips and the MOSFETs/VRMs.

ZOTAC was definitely thoughtful of providing adequate cooling to the power delivery circuitry of the graphics card. They also have not forgotten about the adequate cooling of the VRAM chips as the main copper plate is making a contact with these chips with thermal pads in between.

The ZOTAC GeForce GTX 1660 Ti packs 3x 6mm nickel-plated copper made pipes making direct contact with copper plates. I wish I could open the card to show exactly how this all has been set up but due to restriction at source, I could not do that.

Now that we have looked at the cooling solution, it is time to take a look at the top side of the ZOTAC GeForce GTX 1660 Ti Amp edition. This side shows the wraparound approach of the metallic back plate having vents. These are for proper ventilation. There is a glossy black middle portion with ZOTAC GAMING branding printed in the white color.

There is no LED underneath it. GEFORCE GTX is printed on the rightmost side of the shroud. Notice the depth of the PCB with respect to the top. There is like 15mm or so gap from the top side to the PCB. This is to accommodate the protruding heat pipes in the middle. I have one complaint here. This particular design makes it a bit inconvenient to connect the power connector to the graphics card.

This side again is showing the all close approach to my liking. The metallic backplate is wraparound to cover half of this side with the rest of the side being covered by the shroud. The top and the bottom sides of the shroud are sharply protruding adding more aggression to the looks. The back plate portion here has vents for proper ventilation and not to deprive the card of the fresh air.

Taking a peek at the bottom side of the ZOTAC GeForce GTX 1660 Ti would show that the PCB is in black color and that there is a gap of approximately 39mm or so between the PCB’s ending side to the shroud of the graphics card. This design is to cater for the wide array aluminum heatsink and to have another 90mm fan. Thermal pads of multiple colors have been used. PCIe connector with golden pins is also visible.

Let’s take a look at the backside of the graphics card. One gets to see the stunning designed gray color metallic backplate having ZOTAC brand logo in silver color below the power connector. LIVE TO GAME tag line is printed towards the other end of the backplate. The backside of the GPU is exposed.

There is no thermal pad between the backside of the PCB and the backplate and a certain gap can be seen. This card has no SLI finger or NVLink as NVIDIA did not provide this feature in RTX 2070 and below in the Turing architecture.

The ZOTAC GeForce GTX 1660 Ti Amp edition has a single 8-pin power connector. The card is rated for 130W power and minimum recommended PSU is 450W.

Following connectivity options are available on the ZOTAC GeForce GTX 1660 Ti Amp edition:

• 3x Display Ports 1.4
• 1x HDMI 2.0b

In terms of the overall performance, the ZOTAC GeForce GTX 1660 Ti has performed superbly in 1080p gaming. In a few titles, it was sitting between the GeForce GTX 1070 and the GeForce GTX 1070Ti and in some, it was touching the performance level of the GeForce GTX 1070.

The average performance boost over the GeForce GTX is above 30% which is very good and clearly gives the right upgrade path to the users of the GeForce GTX 960 and GeForce GTX 1060. I don’t see why a user of the GeForce GTX 1070 and GeForce GTX 1070Ti should opt for the GeForce GTX 1660 Ti.

But it is for sure that if you are looking for a superb gaming experience on 1080p without ray tracing but from Turing architecture, the GeForce GTX 1660 Ti makes its case very strong. It has performed quite well on 1440p gaming as well and it all boils down to the type of the games and the graphics settings to achieve optimal playable gaming experience.

VRAM Analysis

The ZOTAC GeForce GTX 1660 Ti Amp Edition has 6GB GDDR6 of onboard memory from the Micron (from our sample) running at 6001MHz. Since the games are becoming more and more demanding with every day counting, it was only imperative to test if the 6GB would be enough to drive your gaming requirement on the 1080p and the 1440p resolutions.

Since I was at it, I decided to include the 2160p results as well. All of our games have been tested using the maximum possible graphics settings. It is important to understand that the monitoring software only shows the requested memory from the graphics card at any given time.

Either we can show the graph of memory utilization or requested memory (putting it correctly) or mention the maximum amount of the memory that was requested during the benching session of any game. I have opted for the later and my graph is showing the maximum requested memory during that game’s benching session.

Only a few titles were crossing the 6GB cap of this graphics card and even that on 2160p gaming which is beyond the scope of the GeForce GTX 1660 Ti hence it is safe to assume that the 6GB onboard memory would suffice for the titles that I have tested on 1080p and 1440p gaming.

Boost Clocks

Now that we have taken a look at the gaming and synthetic benchmark results along with the VRAM analysis, it is time to take a look at the maximum boost clocks.

The ZOTAC GeForce GTX 1660 Ti Amp Edition has boosted to 1965MHz out of the box without any tweaking. The sustained clocks were on average 1920MHz which is quite impressive.

Overclocking, Power Consumption, and Thermals

For overclocking, the MSI Afterburner was used. I started with overclocking the VRAM only without touching the voltage slider and core clock. I was able to push the memory clock by another +800MHz which is good. Any attempt on going further was met with lowered scores clearly indicating that overclocking attempt was futile to even at 100% voltage bump. Finally, I was able to push the Memory to +800MHz and Core clock to +150MHz.

Power Consumption

To measure the power draw, I am taking a different route as HWInfo64 shows the GPU Power and this is exactly what I have been showing on my graphs instead of overall system power draw.

To monitor the idle power draw, the system was left on idle for 30 minutes with closing as many background apps as possible and loading the Balanced Power Profile in the Windows.

To monitor the maximum power draw, I am using The Witcher 3 4k run of 30 minutes and then record the reported power draw from the HWInfo64. This way any user can check their graphics card for power consumption easily.

This card like the other RTX graphics cards that I have tested, was constantly hitting the power target. Increasing the power slider to 110% saw little improvement. A little more headroom in terms of power target could have been beneficial.

Thermal Performance

I am not using Furmark or any other stress app for thermal performance checking. Instead, the reported temperatures are actually from the gaming session using The Witcher 3 at the 4k resolution for minimum of 30 minutes.

MSI Afterburner is used to record the temperatures during the gaming session. The ZOTAC GeForce GTX 1660 Ti Amp Edition was idling at 39°C. On stock clocks, it maxed to 70°C and with overclocking it maxed to 74°C.

Software

Fire Storm is the name of the utility that ZOTAC provides with their graphics cards and this time they have revamped its design making it more user-friendly and simpler and this is what I am appreciating as well. The user can download the application from their website.

The above picture shows the main interface of the application and a quick look alone suffices to tell how effective this new interface is. We have a ZOTAC logo on the top left side. Next, we have a fan circle showing the fan speed in %age. It has Auto, Manual, and Advanced modes.

The advanced mode will allow the user to create a custom fan curve profile based on the requirements. There is no Auto stop function on this card.

The bottom circle on the main interface shows the GPU thermals.  ZOTAC GAMING is printed on the bottom left side. The main circle in the center is showing the Core Clock and Memory Clock in MHz.

There is a listing of GPU1 up to GPU 4 on the right side of this circle. This allows the user to quickly switch to the respective graphics card in case of using multiple graphics cards. The user can save and load up to 3 profiles for each card.

The rightmost side shows the Advanced options to overclock the graphics card and to increase the power target/voltage. Clicking on the Default button will reset the graphics card’s settings to the factory defaults. Since the ZOTAC GeForce GTX 1660 Ti Amp Edition has no LED lighting hence the Spectra is disabled in the app.

Clicking on the Settings icon will load the new interface. The first option allows the user to monitor the important parameters of the graphics card.

Next, we have various application-related settings.

Information will show the Graphics card’s specifications much like the GPU-Z but in a lesser manner.

I have found the ZOTAC FireStorm application easy to use and without any hiccup. The OC Scanner is a new thing which would determine the optimal possible performance settings in the best manner for the user.

Conclusion

Well, who could have expected NVIDIA to go all out on their Turing architecture, even if that means cutting the very basic variable out of the equation, aka Ray Tracing, closely followed by the Tensor Cores? Well, AMD’s rushed-out RX 590 could have given a clue as to what is coming from the other side!

The all-new TU116 is a revamped GPU from NVIDIA aimed at bringing balanced performance, power, and cost for gamers of 1080p gaming. The very nomenclature of GTX is indicative of the fact that there is no dedicated hardware for the RT and Tensor. This is done to bring the sub $300 cost-effective graphics solution yet remaining inside the Turing architecture.

Today, I have taken a spin on the ZOTAC GeForce GTX 1660 Ti Amp Edition graphics card based on the very same TU116 SM. This is a factory-overclocked card using a custom PCB. The dimension of the graphics card is 209.6×119.3x41mm (LxHxW). This is dual slot design. It is based on TU116 GPU from NVIDIA using 12nm technology with a die size of 284 mm² and packs 6600M transistors.

It has 48 ROP and 96 TMU units with 1536 CUDA Cores or shader units. The pixel fill rate is 89.3 GPixel/s, and the texture fill rate is 178.6 GTexture/s. This card has 6 GB from Micron using GDDR6 with a bus width of 192-bit and a cap at 288 GB/s bandwidth. The base clock on this card is 1500MHz, with a boost clock of 1860MHz. The card is designed to fit in over 90% of the systems with a focus on a compact design, and it comes ready for VR.

The design of the graphics card follows a wraparound approach which is what I have been looking for as it gives better and bold aesthetics. The shroud is made of plastic but is quite sturdy, and it is symmetrical from its sides. It mimics ZOTAC’s brand logo in design from all aspects. The ZOTAC GeForce GTX 1660 Ti Amp Edition features their Icestorm 2 cooling solution. It comprises 2x 90mm fans designed for better static pressure and maximum airflow yet remaining at silent levels of the operations. Then there is a wide array of the aluminum-based heatsink, which has more length and height than the PCB.

It has 3x 6mm nickel-coated copper heat pipes making direct contact with the two nickel-plated copper plates. The main copper plate is making contact with the GPU and the VRAM chips. There are thermal pads between the copper plate and the VRAM chips. The ZOTAC was considerate enough to provide a proper cooling solution for the VRMs as well.

The second copper plate is making contact with the VRMs using the thermal pads. The much larger surface area of the wide array heatsink combined with 2x 90mm fans ensures effective heat dissipation.

The ZOTAC GeForce GTX 1660 Ti Amp Edition has 3x Display Ports 1.4 and 1x HDMI 2.0b port for the connectivity options and has support for multiple displays. It has a single 8-pin power connector and is rated for 130W power.

There is no LED lighting on this card. I could not check for the power phases as I did not open the card due to restrictions from the source. The ZOTAC GeForce GTX 1660 Ti Amp Edition does not have any SLI finger or NVLink, for that matter, which is a design constraint from NVIDIA. The card supports Vulkan 1.0, DX_12, OpenGL up to 4.5 APIs.

The graphics card was put to the test in 14 games using various APIs and at all three resolutions. Yes, I have even checked the performance on 2160p though NVIDIA is clearly aiming this card only for 1080p gaming, and I can see why.

On average, this card has given above 30% performance boost over the GeForce GTX 1060 6GB. This is clearly an upgrade path for the GeForce GTX 960 and GeForce GTX 1060 6GB users. In many titles, this card was found performing in between the performance level of the GeForce GTX 1070 and GeForce GTX 1070Ti.

If you already have a GeForce GTX 1070 or GeForce GTX 1070Ti and thinking of changing the card, then my recommendation would be RTX 2060 over the GTX 1660 Ti. Clearly, NVIDIA has settled for a new champ in 1080p gaming without the ray tracing in the form of the GeForce GTX 1660 Ti.

However, for the price, the GTX 1660 Ti is also quite the bang for the buck.

We are thankful to PakDukaan and ZOTAC for giving us the opportunity to review the ZOTAC GeForce GTX 1660 Ti Amp Edition graphics card.
