Asus ROG Astral GeForce RTX 5080 OC Hatsune Miku Edition

Manufacturer: Asus

The Asus ROG Astral GeForce RTX 5080 OC Hatsune Miku Edition is a distinctively styled graphics card from Asus ROG, sitting within the high-end segment of the GeForce RTX 5080 lineup. Based on Nvidia's Blackwell architecture and manufactured on a 5 nm process, it carries 59.35 TFLOPS of floating-point performance alongside RGB lighting and support for up to four simultaneous displays. The card ships with a factory-overclocked base clock of 2295 MHz and a turbo frequency of 2760 MHz.

On the memory side, the card is equipped with 16GB of GDDR7 VRAM across a 256-bit bus, reaching an effective speed of 30000 MHz and delivering up to 960 GB/s of bandwidth. It supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, and includes Intel Resizable BAR compatibility. Connectivity is handled through two HDMI 2.1b outputs and three DisplayPort connections, with no USB-C or DVI ports present. The card has a rated TDP of 360W and physical dimensions of 357.6 mm in length and 149.3 mm in height.

Pros
  • Supports up to four displays simultaneously, offering flexibility for multi-monitor setups
  • Five video outputs in total — two HDMI 2.1b and three DisplayPort — cover a wide range of display connection needs
  • ECC memory support adds a layer of data integrity for compute-oriented workloads
  • DLSS and ray tracing support are both present, enabling access to these rendering features
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve data transfer efficiency
  • RGB lighting is included, giving the card a visually distinctive appearance
Cons
  • A 360W TDP places significant demands on the system power supply and case airflow
  • No USB-C video output is available, limiting compatibility with certain modern monitors and devices
  • No air-water hybrid cooling is included, relying entirely on air cooling to manage heat at this power level
  • The card's length of 357.6 mm may not fit in smaller or mid-tower cases without clearance issues
  • XeSS (XMX) is not supported, limiting access to that particular upscaling technology
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads that benefit from 59.35 TFLOPS of floating-point performance, 16GB of GDDR7 VRAM, and ECC memory support. Professionals working with GPU-accelerated applications will appreciate the Double Precision Floating Point capability alongside the high memory bandwidth of 960 GB/s. It also fits users who need extensive display connectivity, as the combination of two HDMI 2.1b ports and three DisplayPort outputs supports up to four monitors simultaneously, making it practical for wide desktop setups or content creation environments.

Who is this NOT for?

Users working in space-constrained or compact builds will likely find the 357.6 mm card length a practical obstacle, as many smaller and mid-tower cases cannot physically accommodate a card of this size. The 360W TDP also makes this card a poor fit for systems with modest power supplies or limited case airflow, since sustaining stable operation requires robust thermal and power infrastructure. Additionally, users who rely on USB-C video output for connecting newer displays or portable monitors will find this card unsuitable, as no USB-C port is present among its outputs.

Final Verdict

The Asus ROG Astral GeForce RTX 5080 OC Hatsune Miku Edition is a technically capable graphics card built around Nvidia's Blackwell architecture, bringing together a strong compute throughput, 960 GB/s of memory bandwidth via 16GB of GDDR7 VRAM, and a broad connectivity suite that supports up to four displays. Its inclusion of ECC memory, DLSS, ray tracing, and Intel Resizable BAR rounds out a feature set that serves both rendering-heavy creative tasks and GPU compute use cases. That said, its 360W TDP and 357.6 mm length mean it demands a well-equipped system to operate reliably, and the absence of USB-C output is a practical limitation worth noting. For users who can accommodate its physical and power requirements, this card represents a well-specified option within its category.
