Gainward GeForce RTX 5070 Ti Phoenix GS specifications and in-depth review

Gainward GeForce RTX 5070 Ti Phoenix GS

Manufacturer: Gainward

The Gainward GeForce RTX 5070 Ti Phoenix GS is a desktop graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5 nm process with 45,600 million transistors. It operates at a base clock of 2295 MHz and reaches a turbo clock of 2452 MHz, with RGB lighting and support for up to four simultaneous displays. The card draws 300W TDP and connects via PCIe 5.0, fitting into a wide range of modern desktop builds.

On the memory side, the card is equipped with 16GB of GDDR7 VRAM across a 256-bit bus, delivering a peak bandwidth of 896 GB/s at an effective speed of 28,000 MHz. Its 8960 shading units, 280 texture mapping units, and 96 render output units contribute to a texture rate of 686.6 GTexels/s and a floating-point throughput of 43.94 TFLOPS. Display connectivity includes three DisplayPort outputs and one HDMI 2.1b port, while feature support covers DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR.

Pros
  • Supports up to four simultaneous displays, making it practical for multi-monitor setups
  • Includes DLSS and ray tracing support, enabling access to two widely used rendering technologies
  • ECC memory support adds a layer of data reliability for error-sensitive workloads
  • The 256-bit memory bus paired with 896 GB/s bandwidth allows substantial data throughput
  • Intel Resizable BAR support enables the CPU to access the full GPU frame buffer, which can improve throughput in compatible systems
  • RGB lighting allows for visual customization within a build
Cons
  • A 300W TDP places notable demands on the power supply, requiring a well-specced system
  • The card measures 331.9 mm in length, which may not fit in smaller or compact cases
  • No USB-C display output is available, limiting connectivity options for monitors that rely on that interface
  • Air-water cooling is not supported, so thermal management depends entirely on the card's air-cooling solution
  • No DVI output is present, which could be a limitation for users with older displays
Who is this for?

This card is well suited to users running demanding desktop workloads who need both high rendering throughput and access to modern graphics APIs like DirectX 12 Ultimate and ray tracing. The 16GB of GDDR7 VRAM and 896 GB/s of memory bandwidth make it a solid fit for content creators and technically oriented users who work with large datasets or textures, while ECC memory support adds reliability for those handling precision-sensitive compute tasks. The four-display output capability also makes it a practical choice for users who require expansive multi-monitor desktop configurations.

Who is this NOT for?

Users with compact or small-form-factor systems may find the card's 331.9 mm length a limiting factor, as it will not physically fit in many mini-ITX or similarly constrained enclosures. The 300W TDP also means it is not appropriate for builds with modest power supplies, as it demands a well-provisioned system to operate stably. Additionally, users who rely on USB-C or DVI display connections will find no support for either interface, making this card a poor match for setups that depend on those output types.
