Asus ROG Strix GeForce RTX 4070 Super OC Edition

Manufacturer: Asus

The Asus ROG Strix GeForce RTX 4070 Super OC Edition is a graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process with 35,800 million transistors. It ships with an OC configuration that pushes the GPU turbo clock to 2640 MHz, and the card covers the expected feature set for its generation, including ray tracing, DLSS, DirectX 12 Ultimate, and support for up to four simultaneous displays. RGB lighting and Intel Resizable BAR support are also part of the package.

The card carries 12GB of GDDR6X memory on a 192-bit bus running at an effective speed of 21,000 MHz, yielding a maximum bandwidth of 504.2 GB/s. ECC memory support is included alongside Double Precision Floating Point capability. The GPU counts 7,168 shading units, 224 texture mapping units, and 80 render output units, producing a texture rate of 591.4 GTexels/s and floating-point throughput of 37.85 TFLOPS. Output connectivity consists of two HDMI 2.1a ports and three DisplayPort connections, with no USB-C, DVI, or mini DisplayPort outputs present. The card has a TDP of 225W, connects via PCIe 4.0, and measures 338.9 mm in length and 149.4 mm in height, relying on air cooling without a water-cooling option.

Pros
  • Five physical display outputs — two HDMI 2.1a and three DisplayPort — allow flexible multi-monitor configurations up to four screens
  • DLSS and ray tracing support are both included, broadening rendering options for compatible workloads
  • ECC memory support adds data reliability for users running compute tasks alongside standard graphics workloads
  • A 225W TDP is relatively modest for this class of card, placing less strain on system power delivery
  • Intel Resizable BAR support enables the CPU to access the full GPU frame buffer, improving data transfer efficiency
  • Double Precision Floating Point capability extends the card's usefulness beyond graphics to 64-bit compute tasks
Cons
  • The 192-bit memory bus width is narrower than higher-tier cards in the same generation, which constrains available memory bandwidth to 504.2 GB/s
  • No USB-C, DVI, or mini DisplayPort outputs are available, limiting connectivity for displays that rely on those interfaces
  • At 338.9 mm in length, the card may not fit in compact or smaller mid-tower cases
  • Air-water cooling is not supported, restricting thermal management to air cooling only
Who is this for?

This card is a practical fit for users who want ray tracing and DLSS support in a package with a 225W TDP, making it easier to accommodate within systems that have moderate power headroom. The five-port display output configuration — covering two HDMI 2.1a and three DisplayPort connections — suits users managing multi-monitor setups for gaming or productivity. ECC memory support and Double Precision Floating Point capability also make it a reasonable choice for users who occasionally run compute or precision-sensitive workloads alongside standard graphics tasks.

Who is this NOT for?

Users working with very large textures or memory-intensive rendering pipelines may find the 12GB VRAM on a 192-bit bus a limiting factor, as the narrower bus constrains total bandwidth relative to cards with wider memory interfaces. Those building in compact or small-form-factor cases should verify clearance carefully, given the card's 338.9 mm length. Additionally, users who require USB-C display output — whether for certain monitors, docking stations, or portable displays — will find no such port available on this model.

Final Verdict

The Asus ROG Strix GeForce RTX 4070 Super OC Edition is a well-rounded graphics card that combines Ada Lovelace architecture with a broad feature set — including ray tracing, DLSS, ECC memory support, and a five-port display output configuration — within a relatively contained 225W power envelope. Its 2640 MHz turbo clock paired with 12GB of GDDR6X memory gives it a solid footing for both gaming and occasional compute workloads, though users with very high memory bandwidth demands or compact build constraints should factor in the 192-bit bus width and 338.9 mm card length before committing. For users building in standard full-size systems who want a feature-complete Ada Lovelace card without excessive power requirements, the ROG Strix RTX 4070 Super OC Edition represents a coherent and capable option.
