Gigabyte RTX 4070 Ti Gaming OC:
As a reminder, there will be no ” Founders Edition ” cards offered by NVIDIA for the RTX 4070 Ti. You can therefore only buy partner cards and therefore, depending on the model, with very different prices.
This RTX 4070 Ti has an AD104 GPU with 7680 CUDA cores, which is 2560 cores less than the RTX 3080 Ti. It is equipped with a manufacturing process in 4nm from TSMC and not the 8 nm manufacturing process by Samsung, which allows the TGP to be lowered to 285 watts.
In terms of memory, there are 12 GB of GDDR6X memory in 192-bit, which translates into a bandwidth of 504.2 GB/s. On page four of our article, we will go into detail on the new features of this new architecture, including support for DLSS 3.
The bundle of this Gaming OC:
So what do we find in this box? We find and identify very easily the color code of Gigabyte with black and orange. The box is quite large but still has standard dimensions. The dimensions of the box are 440 x 235 x 95 mm. The box opens on the side to reveal the RTX 4070 Ti Gaming OC.
Once removed, we find a small box that contains the adapter for the power supply of the card. It is a 16-pin (12+4) adapter to two 8-pins of 150w (300w in total). This adapter is necessary for those who do not have a power supply with a 16-pin port or the adapter for their power supply. There is also a support for the graphics card so that it does not bend when inserted in your motherboard.
Cooling:
This Gigabyte RTX 4070 Ti Gaming OC has the dimensions 336 x 140 x 58 mm and will occupy 2.5 slots on your motherboard. This model is part of the Gigabyte “Gaming OC” series. This means that the card is already factory overclocked. Aesthetically, the card plays on sobriety with touches of black, anthracite and dark gray. It is a model that can be matched with many motherboards.
We are dealing here with a custom card, that is to say with a cooling system specific to the brand. It is labelled “Windforce 3x” and has three 100mm fans. Gigabyte uses its patented “Alternate Spinning” technology for this card. The principle is quite simple and involves the three fans rotating in opposite directions. The goal is to avoid turbulence between them.
The nine fan blades are slightly curved to optimize airflow. Our sample features ” 3D Active Fan ” technology to leave the fans idle if the GPU temperature does not require them to run.
The black plastic casing completely encloses the PCB with a very qualitative finish. The aesthetics, quite neutral, should suit many users. Two BIOS are also present, a Silent mode and an OC mode. By default and for our tests, we will use the OC mode.
Radiator:
The heatsink is composed of a single block. As you can see on the pictures, its role is to dissipate the heat from the GPU, the memory chips and the power supply stage.
The heat sink is crossed by simply seven 6 mm heat pipes. These are in direct contact with the graphics chip. The memory chips, the power supply stage and some of the PCB chips are covered with thermal pads to ensure heat dissipation. This is a very strong cooling system that should keep all the components cool!
Finally, we find at the back a backplate whose role is to stiffen the PCB. This one benefits from a very large cut at its end to let the air pass through the radiator. It is easy to imagine that the PCB is much shorter than the heat sink that covers it.
Yes, some backlighting:
Quite a bit of backlighting with the outline of each fan as well as the Gigabyte logo on the top edge of the card and controllable via the RGB Fusion 2.0 software. There are no less than 9 RGB effects that can be set via the software.
The connectors:
To power the card, we find the new 16-pin mini-connectors. As we mentioned above, NVIDIA provides in its bundle an adapter to connect two 8-pin connectors.
The card has three DisplayPort 1.4 video outputs and an HDMI 2.1 port.
