Manufacturer: Asus

The Asus TUF Gaming GeForce RTX 5090 OC Edition is a flagship-tier graphics card from Asus, built on NVIDIA's Blackwell architecture using a 5nm semiconductor process. It carries a base GPU clock of 2017 MHz with a boost speed reaching 2550 MHz, and the card delivers 111 TFLOPS of floating-point performance, placing it firmly at the top of the consumer GPU stack. RGB lighting and support for up to four simultaneous displays round out its feature set for both workstation and enthusiast desktop use cases.

On the memory side, the card is equipped with 32GB of GDDR7 VRAM on a wide 512-bit bus, achieving an effective memory speed of 28,000 MHz and a peak bandwidth of 1,790 GB/s, supported by ECC memory capability. Its 21,760 shading units are paired with 680 texture mapping units and 176 render output units, contributing to a texture rate of 1,734 GTexels/s. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, and connects via one HDMI 2.1b port and three DisplayPort outputs. It uses PCIe 5.0 and measures 348 mm in length and 146 mm in height, with no USB-C outputs present.

Pros

With 32GB of GDDR7 VRAM on a 512-bit bus, the card can handle memory-intensive workloads without running into capacity constraints
Support for up to four simultaneous displays makes it well-suited for multi-monitor setups
ECC memory support adds a layer of data integrity useful for compute and professional workloads
Ray tracing and DLSS are both supported, enabling modern rendering techniques in compatible applications
Intel Resizable BAR support allows the CPU broader access to GPU memory, which can improve frame delivery in supported systems
RGB lighting is built in, offering visual customization without requiring additional hardware

Cons

A 575W TDP places significant demands on system power delivery, requiring a high-capacity PSU and good case airflow
The card does not include air-water cooling, so thermal management relies entirely on the air-cooling solution provided
At 348mm in length and 146mm in height, the card occupies considerable space and may not fit in compact or mid-tower cases
There are no USB-C outputs, limiting direct connectivity options for displays or devices that rely on that port type
XeSS (XMX) is not supported, restricting upscaling options to DLSS only

Who is this for?

This card is well-suited for users who run demanding compute and rendering workloads that benefit from high floating-point throughput, large VRAM capacity, and ECC memory support. Content creators, 3D rendering professionals, and machine learning practitioners working with large datasets will find the 32GB of GDDR7 memory and 1,790 GB/s of bandwidth particularly accommodating. It is also a strong fit for enthusiast desktop builders who want to drive up to four displays simultaneously and take advantage of ray tracing and DLSS in modern applications.

Who is this NOT for?

The card's 575W TDP makes it a poor fit for users with modest or standard power supplies, as the system will require a high-capacity PSU and adequate case ventilation to operate stably. Its physical dimensions — 348mm long and 146mm tall — mean it is not compatible with compact or smaller form-factor cases, effectively ruling it out for space-constrained builds. Additionally, users who rely on USB-C display connectivity or prefer XeSS-based upscaling will find this card lacking, as neither USB-C outputs nor XeSS support are present.
