Gainward GeForce RTX 4070 Super Ghost

Manufacturer: Gainward

The Gainward GeForce RTX 4070 Super Ghost is a graphics card built on NVIDIA's Ada Lovelace architecture, produced on a 5nm process with 35,800 million transistors. It operates at a base clock of 1980 MHz with a boost up to 2475 MHz, and supports ray tracing, DLSS, and DirectX 12 Ultimate alongside multi-display output for up to four screens. RGB lighting is included, and Intel Resizable BAR is supported for more efficient CPU-to-GPU memory access, with the card connecting to the system via PCIe 4.0.

The Gainward GeForce RTX 4070 Super Ghost is equipped with 12GB of GDDR6X VRAM on a 192-bit bus, reaching an effective memory speed of 21000 MHz and a peak bandwidth of 504 GB/s, with ECC memory support also present. Its 7168 shading units, 224 TMUs, and 80 ROPs deliver a floating-point throughput of 35.48 TFLOPS, a texture rate of 554.4 GTexels/s, and a pixel rate of 198 GPixel/s. Output connectivity covers one HDMI 2.1a port and three DisplayPort outputs, with no USB-C, DVI, or mini DisplayPort options, and the card measures 269.1mm in length and 131.8mm in height with a 220W TDP and air-only cooling.

Pros
  • 12GB of GDDR6X VRAM with a 504 GB/s peak bandwidth and ECC memory support covers both graphics and compute workloads with a degree of data integrity assurance
  • Ray tracing, DLSS, and DirectX 12 Ultimate are all supported, enabling a wide range of current rendering and upscaling capabilities
  • Up to four simultaneous displays can be connected through one HDMI 2.1a port and three DisplayPort outputs
  • Intel Resizable BAR is included, allowing the CPU to access the full GPU frame buffer more efficiently
  • Double Precision Floating Point (DPFP) support makes the card viable for compute tasks requiring higher numerical precision
  • A 220W TDP places manageable power demands on the system, giving users flexibility in power supply selection
Cons
  • Only one HDMI port is available, which limits simultaneous HDMI display connections to a single screen
  • No USB-C output is present, requiring an adapter for displays or devices that rely on that interface
  • Air-water hybrid cooling is not supported, restricting thermal management to the card's air-only cooling solution
  • At 269.1mm in length, the card requires adequate case clearance and may not fit in more compact enclosures
Who is this for?

The Gainward GeForce RTX 4070 Super Ghost is well-suited to users who want a card with ray tracing, DLSS, and DirectX 12 Ultimate support for modern rendering workloads, backed by 12GB of GDDR6X VRAM and ECC memory for added reliability in compute-adjacent tasks. Its 269.1mm length and 131.8mm height fit comfortably within most standard ATX cases, making it a practical option for builders who need a capable card without dealing with the fitment challenges of longer models. Users who need up to four simultaneous display outputs via HDMI 2.1a and DisplayPort will also find the connectivity configuration well-suited to multi-monitor setups.

Who is this NOT for?

Users who depend on connecting multiple HDMI screens at once will find the single HDMI port a meaningful constraint, and those with USB-C monitors or peripherals will need an adapter since no USB-C output is available on this card. Anyone requiring air-water hybrid cooling for more aggressive thermal management will need to look at other options, as this card is limited to its built-in air-only cooling solution. The card's 2475 MHz turbo clock also reflects a reference-level boost frequency, which may not satisfy users specifically seeking higher factory overclocked variants of this GPU.
