Galax GeForce RTX 5090 D General

Manufacturer: Galax

The Galax GeForce RTX 5090 D General is a high-end graphics card from Galax, based on NVIDIA's Blackwell architecture and manufactured on a 5nm process node. It carries 32GB of GDDR7 video memory across a wide 512-bit memory bus, delivering a maximum memory bandwidth of 1790 GB/s alongside an effective memory speed of 28000 MHz. The card measures 339mm in length and 151mm in height, and includes RGB lighting as part of its physical design.

On the performance side, the Galax RTX 5090 D General operates at a base GPU clock of 2017 MHz with a turbo frequency reaching 2407 MHz, producing 104.8 TFLOPS of floating-point throughput and a texture rate of 1637 GTexels/s. It is equipped with 21,760 shading units, 680 texture mapping units, and 176 render output units, with a rated TDP of 575W over a PCIe 5.0 interface. Display connectivity consists of one HDMI 2.1b port and three DisplayPort outputs, supporting up to four monitors simultaneously, while feature support extends to DirectX 12 Ultimate, OpenGL 4.6, ray tracing, and DLSS.

Pros
  • 32GB of GDDR7 VRAM across a 512-bit bus delivers extremely high memory bandwidth of 1790 GB/s, suitable for memory-intensive workloads
  • Supports up to four displays simultaneously via one HDMI 2.1b port and three DisplayPort outputs
  • ECC memory support adds a layer of data integrity for compute and professional tasks
  • Includes hardware ray tracing, DLSS, and DirectX 12 Ultimate support, covering a wide range of modern rendering features
  • 92,200 million transistors on a 5nm process reflects a high level of silicon density for this generation
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can improve frame delivery in compatible systems
Cons
  • A TDP of 575W places significant demands on power supply capacity and case airflow
  • No USB-C video output is available, limiting connectivity options for certain modern displays and devices
  • Does not include an air-water cooling solution, meaning thermal management depends entirely on the card's built-in air cooler
  • At 339mm in length, the card requires a sufficiently large chassis to fit properly
  • XeSS (XMX) is not supported, removing that upscaling option for users who rely on it
Who is this for?

This card is well-suited to users who regularly push demanding workloads that require both large frame buffers and high compute throughput. With 32GB of GDDR7 VRAM and ECC memory support, it fits naturally into GPU-accelerated tasks such as 3D rendering, simulation, and machine learning inference. Gamers and creators running ray tracing and DLSS at high resolutions will also find the combination of 104.8 TFLOPS and a 1790 GB/s bandwidth ceiling relevant to their workflows. The four-display output capacity makes it practical for users who need multi-monitor setups for content production or data-heavy environments.

Who is this NOT for?

The card's 575W TDP makes it a poor fit for users with compact or low-wattage builds, as it demands a high-capacity power supply and adequate chassis airflow that smaller form-factor systems typically cannot accommodate. Users working within space-constrained enclosures may also struggle with the 339mm length, which requires a full-size tower or similarly spacious case. Additionally, those who depend on USB-C video output or XeSS upscaling will find neither available here, making this card unsuitable for workflows or display setups that rely on those specific connectivity or rendering features.
