We recently got a glimpse of the simple version of the GeForce RTX 2070. This series also features slightly accelerated Founders Edition graphics cards from NVIDIA and many overclocked models from other manufacturers. In this review, we will consider an ASUS card from the Dual line, evaluate its advantages and overclocking capabilities. And since the operating frequencies are identical to the level of the GeForce RTX 2070 Founders Edition, according to the results, it will be possible to evaluate the difference between different versions of the GeForce RTX 2070.
The video card comes in a large box.
A nice addition to the standard package from the software disk and instructions is a power adapter from two 6-pin connectors to one 8-pin. Buyers also get 6-month access to the wtfast app, which is designed to improve ping in a number of games by working through its optimized GPN gaming network.
Visually, the ASUS Dual GeForce RTX 2070 OC is no different from the previously reviewed ASUS Dual GeForce RTX 2080 video card. We have a massive three-slot device with a pair of large fans. A large radiator is visible under the casing, which occupies the main volume. Length about 27 cm.
The body is black with slight curves and white accents. Looks simple but solid. There is no backlight.
The reverse side is covered with a metal plate. Small cuts are organically combined with a white geometric pattern.
The GeForce RTX and ASUS logos are applied to the side of the casing. In the corner there are two power connectors — six and eight pins.
The set of connectors on the rear panel is standard: three DisplayPort, one HDMI and one VirtualLink (USB Type-C).
The video card is protected from disassembly by a warranty seal, and in this case you will have to do with only an external inspection. Only the plastic cover can be removed. This allows you to better estimate the dimensions of the radiator.
The radiator has a thick massive base, and a row of plates on top. This is a very large structure, but without heat pipes. The same cooling is used in the GeForce RTX 2080 of the Dual line.
On the base there are areas for thermal contact with different elements on the board. Here, a single heatsink is clearly used for the GPU, memory, and power supply circuit elements. Yellow spacers are used as a thermal interface.
In the GPU zone, you can see a large platform.
On the ASUS site you can find a small illustration, which shows through a certain copper plate inside the base. Live, you can see only a small copper element in the corner, near the power connectors.
Inside the thick base there is indeed either a large evaporation chamber or several curved heat pipes. They provide heat dissipation from the contact pad of the base to all radiator fins. One can only guess about the detailed cooling device. But, as we will see below, it is very effective. It should also be noted that the reinforcement plate does not have thermal pads and does not directly cool the board, although this has become standard for many GeForce RTX models.
The radiator is blown by a pair of large fans with an impeller diameter of 9 cm. Their marking is FirstD FDC10U12S9-C.
The board is completely hidden under the heatsink. Therefore, we immediately move on to frequencies and temperature conditions.
The ASUS DUAL-RTX2070-O8G runs at a TU106 base clock of 1410MHz with an average Boost Clock of 1710MHz. And this is fully consistent with the frequencies of the GeForce RTX 2070 Founders Edition. The simplest versions of the GeForce RTX 2070 operate at a combination of frequencies of 1410/1620 MHz. Read more about the positioning of video cards and the difference in frequencies in a separate review of the Turing architecture.
The real GPU frequencies in the gaming load were kept around 1800 MHz. In the heavy benchmark Final Fantasy XV: Windows Edition in 4K mode, frequencies ranged from 1785-1815 MHz.
The temperature of the core did not exceed 67 °С during testing on an open stand (indoors 20 °С). The fan speed is about 1400 rpm or slightly higher.
When tested in Shadow of the Tomb Raider at WQHD resolution, the average GPU frequencies were closer to 1830 MHz, the peak temperature was up to 68 ° C. Peak Boost values are up to 1905 MHz.
We observed similar temperatures in the same test conditions on the MSI GeForce RTX 2070 Armor 8G graphics card, which runs at a lower Boost. And MSI has a more complicated cooler design with five heat pipes.
If we talk about overclocking, then the increase in base frequency is less than what was achieved on the MSI Armor video adapter. But the resulting Boost is higher and more stable. When the frequency was increased from 1420 MHz to 1520 MHz, the peak Boost reached 2040 MHz. The power limit can be raised by 20%, and this is more than the simplest video cards in the series.
In Final Fantasy XV, when overclocked, the frequencies varied in the range of 1935-1980 MHz. The MSI GeForce RTX 2070 accelerator in the same test at a higher base value showed 100 MHz less. The memory was overclocked to 15752 MHz, which is slightly lower compared to MSI.
In Shadow of the Tomb Raider, frequencies were kept at the level of 1980-2010 MHz.
By increasing the fan speed to 1800 rpm, we managed to keep the operating temperatures at the initial level. Noise is moderate. Under harsher operating conditions, overclocking may require more fan acceleration. Perhaps for a compromise and a more pleasant acoustic mode, you should not increase the frequencies to the maximum, but in general, overclocking is not associated with high noise.
