Asus ROG Astral GeForce RTX 5080 OC Doom Edition

Manufacturer: Asus

The Asus ROG Astral GeForce RTX 5080 OC Doom Edition is a high-specification graphics card designed around Nvidia's Blackwell architecture, fabricated on a 5 nm process with 45,600 million transistors. It ships with 16GB of GDDR7 memory across a 256-bit bus, delivering a maximum memory bandwidth of 960 GB/s at an effective memory speed of 30,000 MHz. The card supports up to four simultaneous displays and includes RGB lighting as part of its feature set.

On the compute side, the RTX 5080 OC Doom Edition operates at a base GPU clock of 2,295 MHz with a turbo frequency reaching 2,760 MHz, translating to 59.35 TFLOPS of floating-point performance and a texture rate of 927.4 GTexels/s. Its 10,752 shading units are accompanied by 336 texture mapping units and 112 render output units. The card has a TDP of 360W, connects via PCIe 5.0, and offers a display output configuration of two HDMI 2.1b ports alongside three DisplayPort outputs. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR.

Pros
  • Supports up to four simultaneous displays with five physical output ports, including two HDMI 2.1b and three DisplayPort connections
  • 59.35 TFLOPS of floating-point performance combined with 10,752 shading units makes this card suitable for demanding rendering workloads
  • 16GB of GDDR7 memory running at an effective 30,000 MHz delivers 960 GB/s of bandwidth, supporting high-resolution and data-intensive tasks
  • ECC memory support adds reliability for compute workloads where data integrity matters
  • DLSS and ray tracing support are both present, enabling advanced rendering techniques in compatible applications
  • Intel Resizable BAR is supported, allowing the CPU broader access to GPU memory for optimized data throughput
Cons
  • A 360W TDP places significant demand on system power delivery and requires adequate cooling infrastructure
  • The card measures 357.6 mm in length, which may not fit in smaller or mid-tower chassis without careful clearance checks
  • Air-water cooling is not included, so thermal management relies entirely on the installed air cooling solution
  • No USB-C output is available, limiting direct connectivity options for displays or devices that rely on that interface
Who is this for?

This card is well-suited for users running high-resolution, graphics-intensive workloads such as 4K or multi-monitor gaming and content creation, where the 16GB of GDDR7 memory and 960 GB/s of bandwidth provide headroom for demanding scene complexity and texture loads. The presence of DLSS, ray tracing, and DirectX 12 Ultimate support makes it a practical fit for those working with or playing titles that leverage modern rendering pipelines. Additionally, the ECC memory support and 59.35 TFLOPS of floating-point throughput make it relevant for users engaged in GPU-accelerated compute tasks where both speed and data integrity are priorities. The five-port display output, supporting up to four simultaneous screens, also suits professionals who rely on multi-display setups for productivity or monitoring workflows.

Who is this NOT for?

Users working within compact or small-form-factor builds will likely find this card impractical, as its 357.6 mm length demands a full-size or large mid-tower chassis with sufficient internal clearance. The 360W TDP also makes it a poor match for systems with modest power supplies or limited airflow, as the thermal and electrical demands require a well-provisioned setup to operate stably. Those seeking USB-C display connectivity will need to look elsewhere, since no such output is available on this card. It is equally unsuitable for users who need an energy-efficient card for light desktop or office tasks, where its power draw would be disproportionate to the workload.
