Gigabyte GeForce RTX 4090 GAMING OC 24G real measurement, wind power performance is very explosive

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

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

To perfectly unleash the ultimate performance of NVIDIA GeForce RTX 4090, GIGABYTE also launched GeForce RTX 4090 GAMING OC 24G with its own unique wind force cooling design.

GIGABYTE WindForce Cooling System

GIGABYTE’s RTX4090 graphics card features three large 11 cm fans, and blade guide grooves have been added to increase the air intake of the fans. sides and the center fan rotating in the opposite direction. The purpose is to reduce the airflow interruption between the fans, so that the cold air can be blown to the cooling fins more efficiently to speed up the heat dissipation efficiency of the card graphics.

In addition, the bearings of the three fans are also equipped with nano-graphene lubricating oil. According to the data provided by Gigabyte, it can extend the service life of fans with oil-sealed bearings by 2.1 times, and it is quieter. in addition, this graphics card also adds the automatic spin-stop design will stop the fan when the graphics card is under low load or the chip temperature is low. This benefit can not only reduce fan noise, but also increase the service life of the fan.

As for the design of the heat dissipation module under the fan, GeForce RTX 4090 GAMING OC 24G uses a large area copper superconducting thermal plate to directly cover the display chip, and as many as 10 copper heat pipes connect’ the chips and the memory and exhaust heat is directed quickly to the cooling fins. The heat dissipation fins on the graphics card also specially adopt a height difference stacking design, in order 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 RTX4090 Gigabyte has added a metal back plate to increase the bending strength of the whole graphics card, and there is also a screen cooling opening design on the right side of the back plate. The main purpose is not only to allow The heat dissipation fins have more stretching space, which not only increases the heat dissipation area of ​​the fins, but also reduces wind resistance, allowing waste heat to be discharged out of the graphics card faster.

Dual BIOS design

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

The power supply plug on the display card also adopts the 12VHPWR connector that conforms to the ATX 3.0 specification, and the maximum power supply can reach 600W. GIGABYTE also provides a 12VHPWR to four 8Pin power conversion cable in the package of this graphics card, but to be on the safe side, it is recommended that users use an ATX 3.0 with a kilowatt or more to direct power output with 12VHPWR, which will be safer .

In terms of output specifications, this graphics card provides three sets of DP1.4 and one set of HDMI2.1 ports, and a single card can support up to four screen outputs. From the side of the output panel, it can be seen that this graphics card not only has a length of about 34 cm, but also a width of about 4 slots in the case to improve the cooling effect. Therefore, players should pay attention to whether their case has enough space to load before buying.

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 is changed .High-end graphics cards have plenty of room to fit without them. wasting the expansion capabilities of the motherboard.

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 letters at the top also have an RGB backlight, and the lighting of both places can be adjusted through the RGB Fusion software provided by GIGABYTE, or synchronized with other devices that also have RGB lighting effects.

As for the accessories provided in the graphics card package, in addition to one to four 8pin power cord, there is also a special set of metal brackets, which can be used to help users fix the graphics card to avoid being too heavy or moving. the graphics card There is a risk of damage to the graphics card when the computer is on.

GIGABYTR Control Center Software

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

In 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 play its due performance.

If you want to customize the fan halo and LOGO lighting effect on the graphics card, you can customize it in the RGB Fusion page. In addition to some default 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.

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