Gainward GeForce RTX 4070 Ti Super Phoenix

Manufacturer: Gainward

The Gainward GeForce RTX 4070 Ti Super Phoenix is a graphics card built on NVIDIA's Ada Lovelace architecture, fabricated on a 5 nm process with 45.9 billion transistors. Running at a base clock of 2340 MHz with a boost frequency of 2610 MHz, it pairs a solid compute configuration with 16GB of GDDR6X memory on a 256-bit bus, yielding up to 672.3 GB/s of memory bandwidth.

The card houses 8448 shading units, 264 texture mapping units, and 96 render output units, producing a texture rate of 689 GTexels/s and a pixel fill rate of 250.6 GPixel/s, with 44.1 TFLOPS of floating-point throughput. It supports ray tracing, DLSS, DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, alongside Intel Resizable BAR and ECC memory. Display output consists of one HDMI 2.1a port and three DisplayPort connections, supporting up to four monitors. The card has a TDP of 285W and measures 328.9 mm in length and 131.1 mm in height, with RGB lighting included and no air-water cooling support.

Pros
  • Supports ray tracing and DLSS, enabling a wider range of rendering techniques for compatible workloads
  • 16GB of GDDR6X memory on a 256-bit bus delivers 672.3 GB/s of bandwidth, well-suited for memory-intensive tasks
  • ECC memory support helps maintain data integrity during compute-sensitive operations
  • Double Precision Floating Point capability extends usability into workloads that require higher numerical accuracy
  • Can drive up to four displays simultaneously via HDMI 2.1a and three DisplayPort outputs
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can benefit frame delivery in supported scenarios
Cons
  • A TDP of 285W places significant demands on system power delivery and thermal management
  • No USB-C output is available, which limits compatibility with certain modern display and device configurations
  • Air-water hybrid cooling is not supported, restricting thermal solution choices to air cooling only
  • The 328.9 mm card length may not fit in compact or mid-tower cases without careful clearance planning
  • XeSS (XMX) is absent, meaning upscaling options are limited to DLSS only
Who is this for?

This card is a good fit for users running workloads that benefit from ECC memory and Double Precision Floating Point support, such as compute tasks where numerical accuracy and data integrity are important. It also suits those building multi-display setups, as it can handle up to four screens simultaneously through its HDMI 2.1a and three DisplayPort outputs. Users whose workflows make use of ray tracing and DLSS will also find the feature set aligned with those needs.

Who is this NOT for?

Users working in compact or small-form-factor systems may find the 328.9 mm card length a difficult fit, as it requires adequate case clearance. Those with a 285W TDP constraint in their build will need to ensure their power supply and airflow can handle the load, as the card relies entirely on air cooling with no hybrid option available. Additionally, users who need USB-C display output will not find it here, making this card a poor match for setups that depend on that connector type.
