INNO3D GeForce RTX 3090 Ti X3 OC to the test: Ampere, last stop

After the GeForce RTX 3090 Ti from ASUS TUF Gaming, let’s take a look at a second model based on NVIDIA’s flagship design, the INNO3D RTX 3090 Ti X3 OC. Overclocked, but not as much as the ASUS model, this solution roughly shares its dimensions: the INNO3D solution is about 5 mm longer, while for the rest they are completely identical going to occupy more or less 3 slots on the motherboard. INNO3D’s proposal has one less connector, as it comes with una HDMI 2.1 e tre DisplayPort 1.4awhile the ASUS boasts an extra HDMI 2.1.

The fundamental technical specifications do not change: on board there is the GPU queen of NVIDIA’s offering, the well-known GA102fully active to offer 10752 CUDA core (against the 10496 of the RTX 3090) and the maximum of the ray tracing and Tensor core units. As we said the chip on this solution is factory overclocked to 1890 MHz as regards the Boost Clock against the reference 1860 MHz indicated by NVIDIA. Next to the GPU we find 24GB of 21Gbps GDDR6X memorywhile the memory bus is 384 bits per a bandwidth of 1 TB / s (1008 GB / s).

INNO3D does not specify the TGP of the card, but knowing that that of a 3090 Ti FE is equal to 450W and that of TUF Gaming is equal to 480W, we expect a value more similar to the ASUS model than to the Founders Edition.

The INNO3D X3 OC comes with a heatsink equipped with three 100mm axial fans: the two external fans rotate counterclockwise, while the one centers clockwise. A choice, according to various manufacturers, which reduces turbulence by improving dissipation and noise. Like the other cards, in the absence of load and with temperatures below a certain threshold, the fans remain stationary.

Covering the radiator we find a solution mostly made of plastic, with metallic accents: aesthetically we like the card, it has a “military” but also elegant style.

In the back is a backplate that completely covers only about half of the board. There is an opening on the back of the GPU area to provide enough space for the capacitors. At the rear end of the card you see it as the PCB does not cover the entire length of the card. Interestingly, the circuit board is NVIDIA reference onein fact it can be seen the classic V shape of the Founders Edition. The daughter opening of this size allows a fan to remove the heat stored in the radiator towards the top of the case, where it can be expelled by the rear case fan or by the upper ones.

On the PCB there are 21 voltage phases and the heat sink consists of a vapor chamber which is located directly above the GPU and memory chips. Unlike the GeForce RTX 3090, there are no memory chips on the back of the PCB, which should have a positive effect on the memory temperatures. To achieve this, NVIDIA and its partners use GDDR6X chips with a capacity of 2GB.

In addition to the GPU and memory chips, the phases are also cooled. This does not happen through the steam chamber but a dedicated solution. Otto heatpipe therefore, they are responsible for transferring heat to the radiator and its multiple fins.

The board is equipped sideways with a single 12VHPWR connector in a central position for the power supply: as we saw for the first custom test, the connector is used only partially and carries up to 450W through the 12 main pins. A 12VHPWR adapter with three 8-pin connectors is provided in the board box for connection to traditional power supplies. On the board, under a small plastic “cap”, there is a connector for connecting the board’s integrated LEDs to an RGB controller (external or via the motherboard). Thus, the lighting effects of the Inno3D GeForce RTX 3090 Ti X3 OC can be synchronized with the rest of the system.

Test setup

All video cards were tested with Microsoft Windows 11 operating system. The test platform consisting of a Core i9-10900K on an ASUS ROG Maximus XII Hero WiFi (Z490) motherboard with G.Skill Trident Z 2x8GB DDR4-4000 (17 -17-17-37) and a Crucial P1 M.2 2280 1TB SSD remains unchanged.

GeForce RTX 3090 Ti compared: ASUS vs INNO3D

We’ve already seen when reviewing the ASUS solution that the GeForce RTX 3090 Ti is the fastest card ever for 4K gaming. Furthermore, sharing the amount of memory of the RTX 3090 is a multipurpose proposition that can be useful for all those rendering loads that require a lot of VRAM.

We also know that all NVIDIA solutions of the generation have superior ray tracing performance compared to AMD’s offerings. Also, I can take advantage of DLSS and lean on the FSR. All this to say that in this article we focus on comparing the two tested customizations. As you can guess by looking at the technical specifications, there is not much to see in reality: they go the same, with a variability of a few fps that can be considered normal from one test session and the other.

Frequency, temperature and consumption

The Ampere GA102 GPU on board the ASUS TUF Gaming RTX 3090 Ti OC has touched one media at 1970 MHz in the actual test sections with Metro Exodus Enhanced Edition, while with the INNO3D we recorded slightly lower peaks which gave us back an average clock of 1945 MHz.

Also in terms of temperatures we can speak of very similar values. The GPU temperature, as you can see by looking at the red and green lines, are very similar, while the hotspot is a few degrees higher in the case of the INNO3D.

Probably this behavior is due to the fact that the starting temperatures of the two tested GPUs were not identical: our fault, we should have started the load test with the cooler INNO3D card. In any case, nothing to worry about.

By virtue of what has been written above, the cooling system immediately starts working with the fans at higher RPM, 2300-2400 RPM at about 85% of the duty cycle. Once accelerated, the heat drops and the fans settle at 2000 RPM, which is around 75%, values ​​similar to those seen in the ASUS implementation. Thus, the noise level is also similar with values ​​between 38 dB with the fans stopped and around 50 dB under load.

The consumption of the GeForce RTX 3090 Ti, as we have seen in the ASUS version of this project, are undoubtedly monstrous. In the case of INNO3D we did not expect anything different:

The two consumption graphs are substantially overlapping with values ​​under load that reach close to 480W. Also in this case, looking at the NVIDIA PCAT screen, the hardware system we use to accurately record the consumption of the video cards, we see that the peak reached is around 500W, even something more in this case, but fortunately it is a data recorded for less than a second.

Conclusions

We have already expressed ourselves in the previous review of the GeForce RTX 3090 Ti as a project, to which we refer you if you have not read our opinion. In short: it is the fastest card around and like the RTX 3090 it looks beyond the gaming market thanks to the high VRAM that can be useful for digital creatives.

If gaming is your only passion, you do not need to focus on an RTX 3090 Ti or a 3090, aspire to the maximum for an RTX 3080 Ti, both for a matter of performance and price gain. Consumption is also high, the numbers do not lie, even if those who aim for these solutions usually do not worry much about this aspect, they mainly look at pure performance.

Let’s talk about the INNO3D GeForce RTX 3090 Ti X3 OC: the card performs at the level of the ASUS proposal that we had praised for its ability to keep many horses at bay and make them express at their best. The GPU temperatures allow for high boost frequencies and do not induce throttling, which is what matters to get the most out of it.

To achieve this, INNO3D used a truly impressive cooling system, with a large and long radiator crossed by eight heatpipes and a vapor chamber dedicated to cooling the GPU and memory. The fans, while obviously audible under load, do not reach excessive levels when compared to much more noisy past projects (we still remember AMD’s Radeon VII), especially taking into account the performance achieved.

We really liked the design of the card from an aesthetic point of view, but clearly it is a subjective parameter and you may not like it. The INNO3D GeForce RTX 3090 Ti X3 OC is currently not available for purchase in Italy, but the few samples sold so far have been marketed for around 2300 euros, an honest price considering the 2250 euros of the Founders Edition indicated by NVIDIA.

Of course, with the next GeForces arriving in the second half of the year, those who don’t have the urgent need to change their graphics card would be better off waiting.
