Gainward GeForce RTX 4070 Ti Super Phantom GS

Manufacturer: Gainward

The Gainward GeForce RTX 4070 Ti Super Phantom GS is a graphics card grounded in NVIDIA's Ada Lovelace architecture, produced on a 5 nm process with 45,900 million transistors. It runs at a base clock of 2340 MHz and boosts up to 2685 MHz, sits within a 285W thermal design power envelope, and connects via PCIe 4. The card measures 328.9 mm in length and 141.1 mm in height, with cooling handled entirely by air.

On the memory side, the card carries 16GB of GDDR6X across a 256-bit bus at an effective speed of 21,000 MHz, yielding a maximum bandwidth of 672.3 GB/s and ECC support for error-sensitive workloads. Its 8448 shading units, 264 texture mapping units, and 96 render output units produce a texture rate of 708.8 GTexels/s and 45.37 TFLOPS of floating-point throughput, with Double Precision Floating Point also supported. The feature set includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, Intel Resizable BAR, and RGB lighting, with output available through one HDMI 2.1a port and three DisplayPort connections for up to four displays.

Pros
  • The 2685 MHz turbo clock is the highest boost frequency among the Phantom series variants, translating to slightly elevated texture and pixel throughput figures
  • 16GB of GDDR6X memory on a 256-bit bus with 672.3 GB/s of bandwidth provides substantial capacity for memory-heavy rendering and compute tasks
  • ECC memory support makes the card suitable for sustained workloads where data integrity matters, beyond typical graphics use
  • Hardware ray tracing and DLSS support allow more complex lighting and image reconstruction techniques without depending entirely on rasterization throughput
  • Support for up to four simultaneous displays makes it a functional fit for multi-monitor productivity and visualization environments
  • Intel Resizable BAR support reduces CPU-to-GPU data transfer bottlenecks by giving the processor broader access to the full frame buffer
Cons
  • At 328.9 mm in length and 141.1 mm in height, the card's physical size limits compatibility with compact or smaller mid-tower enclosures
  • The 285W TDP demands a well-specified power supply, making the card unsuitable for systems with limited power headroom
  • No USB-C, DVI, or mini DisplayPort outputs are available, which restricts compatibility with display hardware that relies on those interfaces
  • Water cooling is not supported, so the card depends entirely on air cooling for thermal management during sustained high-load operation
Who is this for?

The Gainward GeForce RTX 4070 Ti Super Phantom GS is well-suited to users working with demanding 3D rendering, video production, or compute-intensive tasks that can take advantage of 16GB of GDDR6X memory and 672.3 GB/s of bandwidth. Its ray tracing and DLSS support make it a practical choice for users engaged in real-time graphically complex workloads at higher resolutions, while the ECC memory support extends its relevance to those who need reliable data integrity over extended operation. Users managing multi-monitor setups of up to four displays will also find the output configuration accommodating for productivity or visualization environments.

Who is this NOT for?

Users planning to install this card in compact or small-form-factor builds will likely face clearance issues, as the card measures 328.9 mm in length and 141.1 mm in height, making it incompatible with many space-constrained enclosures. The 285W thermal design power also makes it a poor fit for systems with modest power supplies, where insufficient headroom under sustained load can lead to instability. Additionally, users who depend on DVI, USB-C, or mini DisplayPort connections for their display setup will find no compatible outputs on this card, limiting its usability in those specific configurations.
