Asus Prime GeForce RTX 4070 Super OC Edition

Manufacturer: Asus

The Asus Prime GeForce RTX 4070 Super OC Edition is a graphics card from Asus based on Nvidia's Ada Lovelace architecture, fabricated at 5 nm and packing 35,800 million transistors. It runs at a base clock of 1980 MHz and boosts up to 2520 MHz, translating to 36.13 TFLOPS of floating-point performance and a texture rate of 564.5 GTexels/s. With a TDP of 220W and physical dimensions of 269 mm by 120 mm, it connects to the system via PCIe 4.0.

The card carries 12GB of GDDR6X VRAM across a 192-bit bus at an effective speed of 21000 MHz, yielding a maximum memory bandwidth of 504.2 GB/s, with ECC memory support included. On the feature side, it supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3.0, ray tracing, DLSS, stereoscopic 3D, and Intel Resizable BAR, while XeSS is not present. Output options consist of one HDMI 2.1a port and three DisplayPort outputs, supporting up to four displays, though USB-C, DVI, and mini DisplayPort connections are absent. RGB lighting is not included on this model.

Pros
  • DLSS support enables AI-based resolution scaling, broadening compatibility with titles and applications that benefit from upscaling technology
  • 36.13 TFLOPS of floating-point performance and 7168 shading units indicate a substantial compute pipeline for demanding rendering workloads
  • 504.2 GB/s of memory bandwidth delivered via GDDR6X over a 192-bit bus supports high-throughput scenarios in both gaming and creative tasks
  • Ray tracing is supported at the hardware level, enabling accurate lighting and shadow rendering in compatible applications
  • ECC memory support adds data integrity protection, making the card more suitable for reliability-sensitive compute tasks
  • Intel Resizable BAR support allows compatible systems to access the full VRAM pool, which can improve rendering consistency
Cons
  • 12GB of VRAM may feel limiting for workloads that increasingly demand larger memory allocations at higher resolutions
  • XeSS upscaling is not supported, reducing flexibility for users who prefer or require that specific scaling technology
  • A 220W TDP places a notable power demand on the system, requiring adequate PSU capacity and case thermal management
  • No USB-C output is available, which may restrict compatibility with certain display adapters or modern monitors
  • RGB lighting is absent, which may matter to users building systems where visual customization is a consideration
Who is this for?

This card is well-suited for users who prioritize a broad feature set for both gaming and creative workloads, particularly those who benefit from DLSS support for resolution scaling in compatible titles and applications. The combination of 36.13 TFLOPS, a high-bandwidth GDDR6X memory subsystem, and hardware ray tracing makes it a solid fit for users engaged in visually demanding rendering tasks where compute throughput and memory speed both matter. ECC memory support and Double Precision Floating Point capability also extend its appeal to users running reliability-sensitive or compute-oriented workloads alongside conventional graphics tasks. Those on compatible Intel Resizable BAR platforms will additionally benefit from optimized VRAM access patterns.

Who is this NOT for?

Users with workflows that require large VRAM allocations — such as high-resolution texture work or memory-intensive AI tasks — may find the 12GB capacity a limiting factor as demands in these areas continue to grow. The 220W TDP makes this card a poor match for compact or thermally constrained builds where power delivery and heat dissipation are tightly managed, as adequate airflow and PSU headroom are necessary. Users who rely on XeSS upscaling or those seeking AMD SAM compatibility will also find this card unsuitable, given that neither feature is present in this configuration.
