Asus ROG Strix GeForce RTX 5070 OC Edition

Name: Asus ROG Strix GeForce RTX 5070 OC Edition
Brand: Asus
SKU: 22575

Manufacturer: Asus

The Asus ROG Strix GeForce RTX 5070 OC Edition is a desktop graphics card based on Nvidia's Blackwell architecture, manufactured on a 5 nm process and housing 31.1 billion transistors. It ships with RGB lighting and supports up to four displays simultaneously, making it a versatile option for multi-monitor setups. The card operates at a base clock of 2325 MHz and reaches a turbo clock of 2512 MHz, with a rated TDP of 250W and physical dimensions of 332 mm by 147 mm.

On the memory side, the RTX 5070 OC Edition is equipped with 12GB of GDDR7 VRAM running across a 192-bit bus at an effective speed of 28000 MHz, delivering up to 672 GB/s of bandwidth. The card provides 6144 shading units, 192 texture mapping units, and 80 render output units, translating to a texture rate of 482.3 GTexels/s and a floating-point throughput of 30.87 TFLOPS. Connectivity is handled through two HDMI 2.1b ports and three DisplayPort outputs, with support for DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, and Intel Resizable BAR.

Pros

Supports up to four simultaneous displays, 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 useful for compute-oriented tasks
DLSS and ray tracing are both supported, enabling more advanced rendering options
RGB lighting is built into the card for those who want visible customization in their system
Double Precision Floating Point (DPFP) support broadens the card's usability beyond standard graphics workloads

Cons

The 192-bit memory bus width is relatively narrow for a card at this tier, which may limit memory throughput scaling
No USB-C output is available, which can be a limitation when connecting certain modern displays or adapters
Water-cooling is not supported; the card relies solely on air cooling, which may be a drawback in thermally constrained builds
At 332 mm in length, the card requires a sufficiently spacious case to fit properly
A 250W TDP places meaningful demands on the system power supply and case airflow

Who is this for?

This card is well-suited to users who want to run ray tracing and DLSS in demanding graphics workloads, given its support for both features alongside DirectX 12 Ultimate. The combination of 12GB GDDR7 VRAM, a 672 GB/s memory bandwidth, and Double Precision Floating Point support also makes it a reasonable fit for compute and content creation tasks that benefit from fast memory throughput and broader floating-point capabilities. Those running multi-display setups of up to four screens will find the five-output configuration — two HDMI 2.1b and three DisplayPort — particularly accommodating.

Who is this NOT for?

Users working in environments where thermal management is already a challenge may find this card difficult to accommodate, as its 250W TDP and air-only cooling solution require good case airflow and a capable power supply. The 192-bit memory bus may also be a limiting factor for workloads that rely heavily on sustained memory bandwidth at scale, making it less suitable for the most memory-intensive professional applications. Additionally, at 332 mm in length, the card is not a practical fit for compact or small-form-factor builds where physical space is a primary constraint.
