Gigabyte Aorus GeForce RTX 5090 Xtreme WaterForce WB

Manufacturer: Gigabyte

The Gigabyte Aorus GeForce RTX 5090 Xtreme WaterForce WB is a flagship graphics card from Gigabyte's Aorus line, designed around Nvidia's Blackwell GPU architecture. It ships with 32GB of GDDR7 memory across a 512-bit bus, and integrates a water block cooling solution alongside RGB lighting. The card carries a four-year warranty and supports up to four simultaneous displays.

At the core of this card are 21,760 shading units, 680 texture mapping units, and 176 render output units, with a boost clock reaching 2,655 MHz and 115.5 TFLOPS of floating-point performance. Memory bandwidth reaches 1,790 GB/s at an effective speed of 28,000 MHz, while the 5 nm fabrication process houses approximately 92.2 billion transistors. The card supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR, and connects via one HDMI 2.1b port and three DisplayPort outputs. It draws power through a PCIe 5.0 interface and carries a thermal design power rating of 575W.

Pros
  • 32GB of GDDR7 VRAM across a 512-bit bus provides substantial memory capacity and bandwidth at 1,790 GB/s, suitable for memory-intensive workloads
  • Water block cooling solution is included, allowing the card to be integrated directly into a custom liquid cooling loop without needing a separate cooler
  • Supports up to four simultaneous displays through a combination of one HDMI 2.1b port and three DisplayPort outputs
  • ECC memory support adds a layer of data integrity protection, which is useful in compute-oriented or professional workloads
  • A four-year warranty period is longer than what is commonly offered for graphics cards
  • Does not have LHR limitations, meaning full GPU operation is unrestricted
Cons
  • A TDP of 575W places significant demands on the power supply and system cooling infrastructure
  • The water block design requires a compatible custom liquid cooling loop, adding complexity and cost to system building
  • No USB-C video output is available, which may limit compatibility with certain monitors or adapters
  • A single HDMI port may be restrictive for users who rely on multiple HDMI-connected displays
  • XeSS (XMX) is not supported, limiting upscaling options to DLSS only
Who is this for?

This card is well-suited to users running demanding rendering, compute, or AI workloads that benefit from large VRAM capacity, high memory bandwidth, and ECC memory support. Its water block design makes it a natural fit for those already operating or planning a custom liquid cooling loop, where thermal management is a priority. The four-display output capability and support for ray tracing, DLSS, and DirectX 12 Ultimate also make it appropriate for users engaged in high-end gaming or real-time visualization who need both visual feature support and ample memory headroom.

Who is this NOT for?

This card is not a practical choice for users with standard air-cooled builds, as the water block requires a compatible custom loop and does not function as a standalone cooler out of the box. Its 575W TDP also makes it unsuitable for systems with modest power supplies or limited airflow, since the surrounding infrastructure must be capable of handling that load reliably. Additionally, users who depend on USB-C video output or multiple HDMI connections will find the port configuration restrictive, as the card offers no USB-C display output and only a single HDMI port.
