Gainward GeForce RTX 4070 Ti Super Phoenix GS

Manufacturer: Gainward

The Gainward GeForce RTX 4070 Ti Super Phoenix GS is a graphics card built on the Ada Lovelace architecture, manufactured on a 5 nm process with 45,900 million transistors. It runs at a base clock of 2340 MHz and reaches a turbo frequency of 2760 MHz, producing 46.63 TFLOPS of floating-point performance alongside a texture rate of 728.6 GTexels/s and a pixel rate of 264.9 GPixel/s through 8,448 shading units, 264 texture mapping units, and 96 render output units.

The card is fitted with 16GB of GDDR6X memory at an effective speed of 21,000 MHz across a 256-bit bus, yielding a maximum bandwidth of 672.3 GB/s, with ECC memory support also present. Its feature set includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, Intel Resizable BAR, and RGB lighting, while display output is provided through one HDMI 2.1a port and three DisplayPort outputs for up to four simultaneous screens. The card carries a 285W TDP, connects via PCIe 4, and measures 328.9 mm in width and 131.1 mm in height.

Pros
  • A boost clock of 2760 MHz is notably higher than the base 2340 MHz, translating to 46.63 TFLOPS of floating-point throughput and a texture rate of 728.6 GTexels/s for graphics-intensive workloads
  • The 16GB of GDDR6X memory running at 21,000 MHz across a 256-bit bus delivers 672.3 GB/s of bandwidth, providing solid capacity for demanding rendering and compute tasks
  • Ray tracing, DLSS, and DirectX 12 Ultimate are all supported, giving the card coverage across modern real-time rendering techniques
  • ECC memory support is present, extending reliability for professional and compute workloads where memory accuracy matters
  • Four-display output support via one HDMI 2.1a port and three DisplayPort outputs offers practical multi-monitor flexibility
  • RGB lighting is included, which benefits users who want visual consistency in a lit system build
Cons
  • At 328.9 mm in length, the card requires careful case compatibility checks, as it may not fit in smaller or mid-tower enclosures
  • The 285W TDP demands a well-configured power supply and adequate case airflow, which may complicate installation in thermally constrained systems
  • No USB-C outputs are available, limiting direct connectivity with monitors and devices that rely on that interface
  • Water cooling is not supported, so thermal management depends entirely on the card's air cooling solution
  • XeSS (XMX) is not present, meaning hardware upscaling options are confined to DLSS only
Who is this for?

This card is well-suited for users engaged in compute-intensive rendering and real-time graphics workloads that can take advantage of a 2760 MHz boost clock, 46.63 TFLOPS of floating-point throughput, and 672.3 GB/s of memory bandwidth. The combination of ray tracing, DLSS, and DirectX 12 Ultimate makes it a practical choice for those working in modern graphics pipelines where these features are regularly exercised. ECC memory support and four-display output capability further extend its appeal to users running professional multi-monitor setups where data integrity and display flexibility are both relevant considerations.

Who is this NOT for?

Users with compact or space-constrained builds may find the 328.9 mm card length difficult to accommodate without verifying case compatibility in advance. Those who require USB-C display connectivity will find no such output on this model, which could limit compatibility with certain monitors and peripherals. Additionally, users who prefer water-cooling configurations for more controlled thermal management will need to look elsewhere, as this card supports air cooling only.
