Asus GeForce RTX 2080 DUAL OC Graphics Card Review – HardwareBunker
Introduction
Graphics, graphics, graphics! If it wasn’t for the humble graphics card and the pursuit of improved gaming visuals, we probably would be playing board games. Instead, since the concept and initial applications of a graphical interface and “moving pictures” in electronic games began, the consumers demanded more, and in general the engineers in the respective hardware and software companies have tried to deliver. Fast forward to 2019 and finally in consumer game titles and graphics hardware, here is a mainstream attempt at Ray Tracing, long-standing visual effects promise that’s just about to come true.
Nvidia have developed a consumer grade implementation of a technology first technically presented in the early 1980s, with a caveat. Ray Tracing in graphics is “a rendering technique for generating an image by tracing the path of light as pixels in an image plane and simulating the effects of its encounters with virtual objects. ”
Nvidia’s RTX is a partial implementation of Ray Tracing and needs Microsoft’s DirectX Ray Tracing (DXR) API to work currently. Rather than a full Ray Tracing implementation, it implements a rasterization technology with Ray Tracing where applicable. I think a lot of people were upset by this, expecting a full Ray Tracing capability from Nvidia, and Nvidia’s marketing is partly to blame here as well, but to have a 100% Ray Traced game would have required more than a graphics hardware vendor to introduce capable hardware, and it would still be outside of the consumer market price range, but we’re getting there now.
What Nvidia have really done, like it or not, is start on the path which has always been promised. What we need now, is AMD to get on with it and produce a competitive market, moving both vendors forward in a Ray Tracing war!

Anyway, the Asus GeForce RTX 2080 DUAL OC 8GB graphics card is what we are reviewing today, a binned and slightly overclocked TU104 graphics chip on what appears to be, reference design PCB. We didn’t strip the PCB down for this reason, though if we learn of suspect this is non a reference PCB, we will and update this article in the future.
What’s not a reference design, is the large dual fan and double slot heatsink design. Full dimensions are 11.8 ” x 5.13 ” x 2.13 ” inches /29.97 x 13.04 x5.41 centimetres which makes the Asus RTX 2080 DUAL OC a large and chunky 2.7 slot card and heavy at nearly 1.4 kg.

Reddit — Dive into anything
I received this card yesterday from NewEgg (ordered on Friday). Over the weekend I was reading up on reviews for this particular model and most seemed to be fairly negative. Some of the comments/reviews I read included that it had a bad cooler design, no heatpipes, ran too hot, hit 85C out of the box, etc.
Here are my findings:
-
First, my case & cooling setup for reference: Corsair 760T case with two front 140mm intake fans, one rear 140mm exhaust fan, and a 5930K @ 4.6GHz cooled by an h215i GT AIO mounted at the top of the case with its two fans exhausting heat out the top.
-
Heat pipes: in a Youtube disassembly video of an Asus Dual 2080 OC (non-Ti) you can see that there are heatpipe outlines on the surface of the plate which indicate to me that the card does have heatpipes, but they’re embedded inside that plate so they are merely hidden.
This is assuming the 2080 Ti has the same part as the 2080 in said video (I don’t have video link right now but I’ll update later if I am able to find it).
-
Heatsink: it truly is massive. This is a very substantial card (2.7 slot I believe).
-
Cooling performance out of the box: The fans cap out at 50% speed on default settings, and I believe this is largely the reason this card has gotten negative reviews with regards to cooling. However, with my particular setup during benchmarks, the card never went above 68C on stock fan settings @ stock clock speeds. The fan was hitting 49-50% and holding there, but temps never went past 68. I did some initial overclocking without touching the fan curve and even then it didn’t go past 72C in benchmarks.
-
Overclocking performance, noise, and temps with a custom fan curve: So far my card is able to hold +140 core (~2125MHz peak boost clock) & +500 memory with what I would call «tentative stability» (I don’t consider a few hours of testing to be enough to call it 100% stable, but I haven’t had any crashes yet).
It would hold memory clocks up to at least +600 but performance was beginning to drop slightly. I still need to test higher memory offsets. I applied a custom fan curve that sits at a static 48% from 0-48C, then rises 1:1 from 48-80C (e.g. 60C = 60%), then a static 100% above 80C. With this OC + fan curve the card never went into the 70s for temps, probably because of the large heatsink. The fans never reached a point where they became significantly louder than my other case + CPU fans. If I crank them to 100% you can notice the noise, but that speed isn’t really needed.
Just thought I’d share my findings since they’re nothing like the negative reviews I’ve seen thus far. I question whether or not those reviewers have an adequate case + cooling setup; I could certainly see temps getting higher with a tiny case or janky fan setup. That said, Asus probably shouldn’t have capped their stock fan curve at a mere 50% speed either.
and where is the competition? GECID.

If you have already decided to buy the flagship NVIDIA GeForce RTX 2080 Ti video card, and mentally resigned yourself to spending an impressive amount, then all that remains is to decide on the modification and manufacturer that suits you. And in order to make the selection process easier for you, we will try to introduce you to the largest number of interesting versions, from the simplest to the original ones with a pre-installed liquid cooling system.
Today we will talk about a fairly standard version of the flagship video card from the ASUS DUAL line. Against the background of many competitive analogues, it stands out for its not the largest dimensions (length less than 30 cm) and a slightly more affordable cost.
The ASUS DUAL series often includes three versions of each video card. Between themselves, they differ in varying degrees of factory overclocking or its complete absence. The situation with the NVIDIA GeForce RTX 2080 Ti was no exception. The first to come to us for the test was ASUS Dual GeForce RTX 2080 Ti Advanced edition . By tradition, we will begin our acquaintance with the study of its performance characteristics.

0 x16 Packing and contents
The ASUS DUAL-RTX2080TI-A11G video card is delivered in a cardboard box with informative color printing. On its sides you can find an image of a video accelerator and a list of its key advantages.
Already a traditional nice bonus is a free 6-month premium subscription to the WTFast Gamers Private Network service. It automatically optimizes the path of game packets between the user’s computer and the game server to minimize their loss and reduce the average response time (ping).
The list of system requirements for the computer is located on one of the sides of the box. Based on the recommendations, the power supply should be at least 650W and support two 8-pin PCIe cables.
In the kit, we found only standard documentation and a software CD.
Reference set of interfaces used for image output:
- 1 x USB Type-C;
- 1 x HDMI 2.0b;
- 3 x DisplayPort 1.4.
The maximum resolution is 7680 x 4320.
Appearance
In terms of appearance, ASUS DUAL-RTX2080TI-A11G is no different from its younger counterparts in the ASUS DUAL GeForce RTX lineup 20. We are met by an already well-known black plastic casing with a small pattern and a pair of white stripes.
On the backlight, the manufacturer decided to save money, although many will like it.
There is a metal support plate on the reverse side. It is designed to protect the printed circuit board from bending and prevent possible damage to components during inaccurate installation and operation. During operation of the video card, the plate heats up, taking a passive part in heat dissipation. Outwardly, it also does not look boring or monotonous.
Unlike the NVIDIA GeForce RTX 2060 and NVIDIA GeForce RTX 2070, both older video cards support the organization of multigraphic bundles. However, the old NVIDIA SLI bridges are not suitable for this purpose — you need to purchase a new NVLink Bridge.
The tested graphics adapter is powered by a PCI Express 3.0 x16 slot and two 8-pin PCIe connectors. They’re nicely placed at the back of the board, so the cooler doesn’t make it difficult to unplug the PCIe cables.
The video accelerator is based on the 12nm NVIDIA TU102-300A GPU.
It consists of 4352 CUDA cores, 272 texture units and 88 raster units. Testing was carried out in the «Gaming» mode, in which the base frequency is declared at the level of 1350 MHz, and the dynamic one is 1560 MHz (the reference indicator is 1545 MHz).
The video memory is made up of Micron’s 11 GB GDDR6 chips, which operate at a reference effective frequency of 14000 MHz. Data exchange between the graphics core and memory is carried out through a 352-bit bus, which is capable of passing 616 GB of information per second.
If desired, two more profiles can be activated in the proprietary GPU Tweak II utility: “Silent” and “OC”. In the first, the dynamic frequency of the GPU is reduced to 1545 MHz, and in the second it is raised to 1575 MHz. The parameters achieved during manual overclocking can be saved to user profiles for quick activation of overclocking in the future.
We were not allowed to disassemble the video card, but thanks to our reader, photos of the internal layout and element base were obtained.
They clearly show that a reference 13 + 3-phase power subsystem is used, which is controlled by two uPI uP9512P PWM controllers.
Cooling system
The ASUS Dual GeForce RTX 2080 Ti Advanced edition video card with the installed cooling system takes up almost three expansion slots (2.7) and has a total length of 278 mm, but inside the case it occupies 268 mm.
The cooler uses a massive radiator with transverse fins. There are no heat pipes in the design.
A pleasant bonus is the contact of the elements of the power subsystem and video memory chips with the heatsink using a thermal interface.
Active heat dissipation is provided by a pair of fans with 88 mm blades and an improved wing-blade shape for increased airflow. The turntables are also protected from dust according to the IP5X standard, and at low loads on the GPU, they suspend their work.
With automatic fan speed control, in maximum load mode, the graphics core heated up to 73 ° C at a critical rate of 89 ° C, and the turntables spun up to 1746 rpm (53% of their maximum power).
According to subjective sensations, the noise was very low and did not interfere with work at all.
For comparison, let’s take a more powerful 3-fan cooling system ASUS ROG Strix GeForce RTX 2080 Ti OC edition, which in a similar mode kept the GPU temperature at 60 ° C with a comparable noise level. But her GPU frequency was higher: 1680 versus 1605 MHz for the ASUS DUAL version.
In the maximum fan speed mode (3000 rpm), the GPU temperature dropped to 59°C. The noise exceeded the average level and became uncomfortable for continuous use.
As for the cooling system on the ASUS ROG Strix GeForce RTX 2080 Ti OC edition video card, it cooled the GPU up to 50°C in the same mode. Again, it showed the best result at a higher operating frequency: 1695 versus 1620 MHz for the ASUS DUAL-RTX2080TI-A11G.
In the absence of load, the frequencies of the graphics core and memory were automatically reduced, allowing to reduce power consumption and heat dissipation of the video accelerator as a whole.
In this mode, the GPU temperature did not exceed 46°C. Recall that the fans start to rotate only when the temperature reaches 55°C.
As a result, the cooling system adequately copes with its work, given the features of its design. Although, of course, it cannot and should not compete with the flagship cooler. It is quite enough for both nominal operation and amateur overclocking experiments. Slightly upset only periodic whistle throttles.
