- HDMI Ports: 1 x HDMI 2.1 (The number and type of HDMI outputs the product has.)
- Maximum Resolution: 8K (4320p) (The highest display resolution that the graphics card(s) can support.)
- Maximum Number of Displays Supported: 3
- Advanced Graphics Rendering Technique(s): DLSS 4 (Deep Learning Super Sampling), Ray tracing (Imaging technology designed to improve graphics rendering.)
- GPU Video Memory (RAM): 24 gigabytes (Random-access memory (RAM) is a GPU’s, or graphics cards, short-term data storage, which allows active information to be accessed quickly. The size and type of RAM determines how efficiently the GPU can handle large amounts of information at one time. For example, larger amounts of RAM for gaming or video editing increases performance.)
- GPU Video Memory Type (RAM): GDDR7 (Each type of RAM delivers a different level of speed, bandwidth, energy efficiency and performance.)
- Slot Size: External GPU (A graphics card only requires one PCIe/PCI slot for connection to the motherboard but, depending on size, may block other slots. The slot size listed by the manufacturer is therefore not an exact measurement of the card's size but an indication of how much clearance will be available after it is installed.)
- PCI Express Version: PCI Express 5.0
- Product Height: 2.96 millimeters (The out of box height of the item. Height is measured as the vertical distance from the bottom of the item to the top as it would be primarily used or placed.)
- Product Width: 20.8 millimeters (The out of box width of the item. Width is measured as the horizontal distance from one side of the item to the other as it would be primarily used or placed.)
- Product Length: 15.5 millimeters (The out of box length of the item. Length is measured as the longest dimension of the item.)
- Graphics Processing Unit (GPU): NVIDIA GeForce RTX 5090 (Often referred to as a graphics card, a graphics processing unit (GPU) is the electronic circuitry responsible for manipulating and processing computer graphics/images and accelerating video decoding. Ultimately, a powerful GPU will provide a boost for anything involving visuals, including games, graphic design, and video editing.)
