Asus ROG Astral GeForce RTX 5090 OC Edition

Name: Asus ROG Astral GeForce RTX 5090 OC Edition
Brand: Asus
SKU: 6616

Manufacturer: Asus

The Asus ROG Astral GeForce RTX 5090 OC Edition is a flagship-tier graphics card designed for demanding workloads and high-resolution rendering. Built on NVIDIA's Blackwell architecture and manufactured using a 5 nm semiconductor process, it houses 92,200 million transistors and 21,760 shading units, reflecting a substantial investment in raw compute density. The card carries a 575W TDP, which reflects the scale of its internal hardware, and it features RGB lighting alongside a conventional air-cooled thermal solution.

On the memory side, the card is equipped with 32GB of GDDR7 VRAM running across a 512-bit bus, delivering a maximum bandwidth of 1,790 GB/s at an effective speed of 28,000 MHz — figures that point to serious throughput capacity for memory-intensive tasks. Floating-point performance is rated at 112.3 TFLOPS, with a texture rate of 1,754 GTexels/s and 176 render output units. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, and Intel Resizable BAR, and can drive up to four displays simultaneously through its two HDMI 2.1b ports and three DisplayPort outputs. It connects via PCIe 5 and also supports ECC memory and double-precision floating-point operations.

Pros

32GB of GDDR7 VRAM across a 512-bit bus delivers 1,790 GB/s of memory bandwidth, supporting highly memory-intensive workloads without bottlenecking throughput
Hardware ray tracing and DLSS support are both present, enabling access to modern rendering techniques without requiring additional configuration
Five video outputs — two HDMI 2.1b and three DisplayPort — allow up to four displays to be connected simultaneously, offering flexible multi-monitor setups
ECC memory support adds a layer of data integrity for workloads where memory error correction is important
Double-precision floating-point (DPFP) support extends the card's utility beyond graphics rendering into compute-oriented tasks
Intel Resizable BAR support allows the CPU to access the full GPU frame buffer at once, which can improve data transfer efficiency in compatible systems

Cons

A 575W TDP places significant demands on system power delivery and cooling infrastructure, requiring a well-specced PSU and chassis
The card measures 357.6 mm in width and 149.3 mm in height, which may not fit in smaller or mid-tower cases without careful compatibility checks
Air-water hybrid cooling is not included, so thermal management relies entirely on the conventional air-cooled solution provided
No USB-C output is available, limiting direct connectivity with displays or devices that use only that interface

Who is this for?

This card is well-matched to users running demanding rendering, simulation, or compute workloads that benefit from high memory bandwidth and DPFP support — including 3D artists, visualization professionals, and those working with large datasets. The 32GB GDDR7 VRAM across a 512-bit bus makes it a strong fit for tasks that require retaining large assets or textures in memory without repeated offloading. Users who need multi-display setups of up to four screens will also find the five-output configuration practical, while ECC memory support adds reliability for workloads where data integrity is critical.

Who is this NOT for?

The card's 575W TDP and 357.6 mm physical length make it poorly suited to compact or mid-tower builds where space and power headroom are limited — users with smaller cases or constrained power supplies would face real compatibility challenges. Those looking for USB-C display connectivity will find the port layout restrictive, as no such output is available. Similarly, users who require a hybrid air-water cooling solution for thermally demanding environments will need to look elsewhere, since the card relies solely on conventional air cooling.
