Gainward GeForce RTX 4070 Super Panther OC

Manufacturer: Gainward

The Gainward GeForce RTX 4070 Super Panther OC is a graphics card based on NVIDIA's Ada Lovelace architecture, fabricated on a 5 nm process with 35,800 million transistors. It features RGB lighting and a triple-fan air-cooling setup, with a 220W TDP and physical dimensions of 328.9 mm in width and 128 mm in height.

Performance is driven by 7,168 shading units and 224 texture mapping units, delivering 37.85 TFLOPS of floating-point throughput, a texture rate of 591.4 GTexels/s, and a pixel rate of 211.2 GPixel/s. The GPU boosts up to 2,640 MHz, while its 12GB of GDDR6X memory runs at an effective 21,000 MHz across a 192-bit bus for up to 504 GB/s of bandwidth. The card supports ray tracing, DLSS, DirectX 12 Ultimate, ECC memory, Intel Resizable BAR, and connects up to four displays through one HDMI 2.1a port and three DisplayPort outputs.

Pros
  • A boost clock of 2,640 MHz gives the card a notably elevated operating frequency relative to the base 1,980 MHz, which translates to higher sustained throughput during demanding workloads
  • RGB lighting is included, offering visual customization options for users who prioritize system aesthetics
  • Ray tracing and DLSS support enable more advanced rendering capabilities in compatible titles and applications
  • ECC memory support adds data reliability for compute tasks where memory error correction is important
  • Four display outputs — one HDMI 2.1a and three DisplayPort — provide flexible multi-monitor connectivity
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve rendering efficiency in supported scenarios
Cons
  • The 192-bit memory bus limits the scalability of the card's 504 GB/s bandwidth in scenarios that push very high memory throughput demands
  • Water cooling is not supported, meaning thermal management is restricted to air cooling regardless of the build environment
  • USB-C, DVI, and mini DisplayPort outputs are absent, which may be a limitation for users with displays or devices relying on those connection types
  • XeSS (XMX) upscaling is not supported, reducing compatibility with that particular upscaling path
  • At 328.9 mm in length, the card may not fit in smaller or more compact enclosures
Who is this for?

The Gainward GeForce RTX 4070 Super Panther OC is a solid fit for users who want ray tracing and DLSS-capable rendering without stepping into the highest power brackets, given its 220W TDP and Ada Lovelace architecture. Its 37.85 TFLOPS of floating-point throughput and 2,640 MHz boost clock make it well-suited to graphics-intensive and compute workloads that benefit from high clock headroom, while ECC memory and DPFP support extend its usefulness to users with GPU compute needs alongside gaming. The inclusion of RGB lighting and four display outputs also makes it a practical option for users building visually customized multi-monitor setups.

Who is this NOT for?

Users working in environments that require water-cooling integration will find this card limiting, as only air cooling is supported, which may be a constraint in thermally demanding or custom-loop builds. The 192-bit memory bus places a ceiling on memory bandwidth scalability, making the card less suited to workloads that consistently saturate high-bandwidth memory pipelines at a professional level. Additionally, those who rely on USB-C display connectivity or XeSS upscaling will find neither feature present, which could affect compatibility with certain displays or AI-upscaling workflows.
