Actual measurement of Gigabyte GeForce RTX 4090 GAMING OC 24G, wind power performance is extremely explosive

NVIDIA officially launched the flagship GeForce RTX 4090 a few days ago. Compared with the higher-end RTX 3090 Ti of the previous generation GeForce series, the chip process used in this new graphics card has been upgraded to TSMC 4N, and the number of transistor chip was increased from the original 28.3 billion to 76.3 billion.

Among these, the number of CUDA Cores has also increased from the previous 10752 to 16384, and also counts 128 third-generation RT Cores responsible for ray tracing operations and as many as 512 fourth-generation Tensor Cores responsible for AI operations.

In order to perfectly unleash the maximum performance of NVIDIA GeForce RTX 4090, GIGABYTE also recently launched a GeForce RTX 4090 GAMING OC 24G equipped with its unique wind force cooling design.

GIGABYTE WindForce cooling system

GIGABYTE’s RTX4090 graphics card features three 11cm wide fans and added blade guide grooves to increase the air intake of the fans. In addition, it also introduces the ALTERNATE SPINNING anti-noise design. Simply put, the fans on both sides and the central fan rotate in the opposite direction. The purpose is to reduce the airflow interference between the fans, so that the cold air can be blown to the cooling fins more efficiently to accelerate efficiency of heat dissipation of the graphics card.

In addition, the bearings of the three fans are also equipped with nanographene lubricating oil, which according to data provided by Gigabyte can extend the life of fans with oil-tight bearings by 2.1 times and is quieter. In addition, this graphics card also adds Automatic spin-stop design will stop the fan when the graphics card is under low load or the chip temperature is low. This advantage can not only reduce the fan noise, but also increase the life of the fan.

As for the heat dissipation module design under the fan, GeForce RTX 4090 GAMING OC 24G uses a large area copper superconductive thermal plate to directly cover the display chip, and as many as 10 copper heat pipes connect the chip and the memory. is quickly directed onto the cooling fins. The heat dissipation fins on the graphics card also specially adopt height difference stacking design, so as to greatly increase the total heat dissipation area of ​​the heat dissipation fins, so that the graphics card has a better heat dissipation effect.

Turning to the back, you can see that Gigabyte’s RTX4090 has added a metal back plate to increase the bending resistance of the entire graphics card, and there is also an opening design for screen cooling on the right side of the plate. rear. not only to allow The heat dissipation fins have more extension space, which not only increases the heat dissipation area of ​​the fins, but also reduces the wind resistance, allowing waste heat to be discharged from the graphics card faster .

Dual BIOS design

Gigabyte’s graphics card also specially adopts dual BIOS design. You can see the words OC and SLIENT on the back panel, so that users can switch directly according to their needs. OC mode has already changed the operation of the graphics chip. The clock is regulated at 2535 MHz, so it can perform better than the official standard specification.

The power plug on the video card also adopts the 12VHPWR connector that complies with ATX 3.0 specification, and the maximum power can reach 600W. GIGABYTE also provides a 12VHPWR to four 8Pin power conversion cable in the package of this graphics card, but to be safe, users are recommended to use ATX 3.0 with one kilowatt or more to directly output the power with 12VHPWR, which will be safer.

In terms of output specifications, this graphics card provides three sets of DP1.4 ports and one set of HDMI2.1 ports, and a single card can support up to four display outputs. From the output panel side, you can see that this graphics card is not only about 34cm in length, but also about 4 slots wide in the case to enhance the cooling effect. Therefore, gamers should pay attention to whether their case has enough space to charge it before purchasing.

In addition to the chassis, such a wide design can easily block the PCIe slots of some motherboards. However, the X670E AORUS Master motherboard used this time should have considered this point. There are three slots between the first and second PCIe slots, and the space for M.2 slots has changed. High-end graphics cards have enough space for installation without wasting motherboard expansion capabilities.

In terms of lighting effect design, the three fans on the graphics card have added an RGB halo, which is Gigabyte’s legendary three-ring light effect. The GIGABYTE lettering on the top also has RGB backlighting, and the lights of the two seats can be dimmed via the RGB Fusion software provided by GIGABYTE, or synchronized with other devices that also have RGB lighting effects.

As for the accessories that come in the graphics card package, in addition to one to four 8-pin power cord, there is also a special set of metal brackets, which can be used to help users fix the graphics card to avoid overweight or shifting graphics card There is a risk of damage to the graphics card when the computer is turned on.

GIGABYTR Control Center Software

GIGABYTE’s RTX4090 graphics card can also be paired with GIGABYTR Control Center software, which allows users to directly control the fan speed, lighting effects and clock parameters on the graphics card via this GCC software.

On the Performance page, there is an OC SCANNER function, which can automatically adjust the graphics card to the most appropriate operating clock according to the current system environment, so that the graphics card can perform as expected.

If you want to adjust the fan halo and LOGO lighting effect on your graphics card, you can adjust it in the RGB Fusion page. Besides some preset lighting modes in the software page, users can also customize their favorite lighting colors and synchronize the lighting colors with other RGB devices on the computer.

On the Fan Control page, users can adjust the speed of the graphics card fans. After activating the custom mode, the speed curves of the three fans can be adjusted individually.
