Gainward GeForce RTX 5070 Ti Phantom GS

Manufacturer: Gainward

The Gainward GeForce RTX 5070 Ti Phantom GS is a desktop graphics card based on NVIDIA's Blackwell architecture, fabricated on a 5 nm semiconductor process with 45,600 million transistors. It operates at a base clock of 2295 MHz, reaching up to 2512 MHz in turbo mode, and its physical dimensions of 331.9 mm × 145.6 mm place it in the larger end of the consumer GPU segment.

On the memory side, the card is equipped with 16GB of GDDR7 VRAM across a 256-bit bus, delivering an effective memory speed of 28,000 MHz and a peak bandwidth of 896 GB/s. Compute performance is rated at 45.02 TFLOPS, supported by 8960 shading units, 280 TMUs, and 96 ROPs. The card supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR, and offers four display outputs consisting of three DisplayPort 3 connections and one HDMI 2.1b port, with a TDP of 300W over a PCIe 5.0 interface.

Pros
  • Supports up to four simultaneous displays through three DisplayPort outputs and one HDMI 2.1b port
  • 16GB of GDDR7 VRAM with a 256-bit bus provides substantial memory capacity for demanding workloads
  • ECC memory support adds a layer of data integrity useful in compute-intensive tasks
  • Ray tracing and DLSS are both supported, expanding rendering and upscaling capabilities
  • Intel Resizable BAR is included, enabling more efficient CPU-to-GPU data transfers
  • Double Precision Floating Point support makes the card suitable for certain compute workloads beyond standard graphics rendering
Cons
  • A 300W TDP places significant demands on system power delivery and thermal management
  • The card measures 331.9 mm in length, which may not fit in smaller or compact PC cases
  • Air-water cooling is not supported, limiting cooling configuration options to air-only solutions
  • No USB-C output is available, restricting connectivity for displays or devices that rely on that interface
  • RGB lighting is absent, which may matter to users building visually customized systems
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, given its 45.02 TFLOPS of floating-point performance, DPFP support, and ECC memory, which collectively make it a capable option for GPU-accelerated tasks that require numerical precision. Enthusiast-level gamers who rely on ray tracing and DLSS will find the feature set relevant, and those needing a multi-monitor setup of up to four displays via DisplayPort and HDMI 2.1b will appreciate the connectivity options. The 16GB of GDDR7 VRAM with 896 GB/s bandwidth also makes it appropriate for high-resolution workflows where memory capacity and throughput are critical.

Who is this NOT for?

Users working within space-constrained or compact builds will likely find the 331.9 mm card length a limiting factor, as many small-form-factor cases cannot physically accommodate it. The 300W TDP makes this card a poor match for systems with modest power supplies or limited airflow, since the thermal and power demands are substantial. Additionally, users who specifically require USB-C display output or air-water hybrid cooling will need to look elsewhere, as neither is supported by this card.

Final Verdict

The Gainward GeForce RTX 5070 Ti Phantom GS is a capable and well-specified graphics card built around NVIDIA's Blackwell architecture, bringing together a strong compute profile, ray tracing, DLSS support, and 16GB of high-bandwidth GDDR7 VRAM in a single package. Its DPFP capability and ECC memory support extend its relevance beyond gaming into compute-adjacent workloads, while the four-display output configuration adds flexibility for multi-monitor setups. That said, its 331.9 mm length and 300W TDP mean it demands a suitably large chassis and a robust power setup — factors worth accounting for before committing to a build. For users who can meet those system requirements, it represents a technically complete card with a broad feature set that covers both high-end rendering and GPU compute needs.
