The NVIDIA GeForce RTX 4090 is a high-end graphics card aimed at enthusiasts. It was released on September 20th, 2022. The card utilizes the AD102 graphics processor, specifically the AD102-300-A1 variant, and is manufactured using the 5 nm process. It fully supports DirectX 12 Ultimate, ensuring compatibility with modern games. This also guarantees the card's capability to handle hardware-raytracing, variable-rate shading, and other advanced features in upcoming video games.
The AD102 graphics processor is a sizeable chip, measuring 608 mm², and it boasts an impressive transistor count of 76,300 million. In contrast to the RTX TITAN Ada, which utilizes the same GPU but with all 18,432 shaders activated, NVIDIA has chosen to disable some shading units in the GeForce RTX 4090 to achieve the desired shader count for this particular product. The GeForce RTX 4090 features 16,384 shading units, along with 512 texture mapping units, 176 ROPs (Raster Operation Units), 512 tensor cores to enhance machine learning performance, and 128 raytracing acceleration cores.
he GeForce RTX 4090 is equipped with 24 GB of GDDR6X memory, which is connected through a 384-bit memory interface. The GPU operates at a base frequency of 2235 MHz, and it has the ability to boost up to 2520 MHz. The memory operates at a frequency of 1313 MHz, which translates to an effective speed of 21 Gbps.
The NVIDIA GeForce RTX 4090 is a graphics card that requires three expansion slots for installation. It is powered by a single 16-pin power connector and has a maximum power draw of 450 W. The card offers several display outputs, including one HDMI 2.1 port and three DisplayPort 1.4a ports. It is connected to the rest of the system through a PCI-Express 4.0 x16 interface. The physical dimensions of the card are 304 mm x 137 mm x 61 mm, and it utilizes a triple-slot cooling solution to manage heat. The launch price of the GeForce RTX 4090 was set at 1599 US Dollars.
