Asus ROG Astral GeForce RTX 5080 Dhahab Core OC Edition specifications and in-depth review

Asus ROG Astral GeForce RTX 5080 Dhahab Core OC Edition

Manufacturer: Asus

The Asus ROG Astral GeForce RTX 5080 Dhahab Core OC Edition is a high-end graphics card from Asus's ROG lineup, featuring Nvidia's Blackwell architecture on a 5nm fabrication process. With 59.35 TFLOPS of floating-point performance and a boost clock reaching 2760 MHz, this card targets demanding workloads and gaming scenarios where raw compute throughput matters. It also includes RGB lighting and supports up to four displays simultaneously.

On the memory side, the card carries 16GB of GDDR7 VRAM across a 256-bit bus, delivering a maximum bandwidth of 960 GB/s at an effective speed of 30000 MHz. The 360W TDP reflects its substantial power requirements, while PCIe 5.0 compatibility ensures it fits into current-generation platforms. For connectivity, the card provides two HDMI 2.1b outputs and three DisplayPort outputs. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, alongside Intel Resizable BAR and ECC memory support.

Pros
  • Supports up to four displays simultaneously, making it practical for multi-monitor setups
  • Five video outputs in total, combining two HDMI 2.1b ports and three DisplayPort connections, offer flexible display configuration
  • ECC memory support adds a layer of data integrity for workloads where accuracy matters
  • DLSS and ray tracing support are both present, enabling access to those rendering features
  • Intel Resizable BAR is supported, allowing the CPU broader access to GPU memory during operation
  • No LHR restrictions are in place, leaving compute throughput fully accessible
Cons
  • A 360W TDP places significant demands on the system power supply and case airflow
  • The card measures 357.6 mm in length, which may not fit in smaller or mid-tower cases
  • There are no USB-C outputs, limiting direct connectivity with displays or devices that rely on that port type
  • Cooling is air-only with no air-water hybrid option, which may be a drawback for users seeking more aggressive thermal management in confined builds
  • 16GB of VRAM, while substantial, is delivered over a 256-bit bus rather than a wider interface
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads that benefit from high floating-point throughput, GDDR7 memory bandwidth of 960 GB/s, and Double Precision Floating Point support. Content creators and technical users who need ECC memory for data integrity will find those capabilities directly available. It also fits well in multi-display desktop setups, given its five video outputs and support for up to four screens, and users who want access to ray tracing and DLSS within supported applications will find both features present.

Who is this NOT for?

The card's 360W TDP and 357.6 mm length make it a poor fit for compact or small-form-factor builds where physical space and power headroom are limited. Users with cases designed for shorter cards or systems equipped with modest power supplies will face compatibility challenges. Additionally, those looking for USB-C display output will find none available here, which rules out direct connection to monitors or devices that depend solely on that interface. The air-only cooling configuration may also be inadequate for users operating in thermally constrained environments who would otherwise benefit from a hybrid cooling solution.
