Gainward GeForce RTX 5070 Phoenix GS

Manufacturer: Gainward

The Gainward GeForce RTX 5070 Phoenix GS is a desktop graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5 nm process with 31,100 million transistors. It runs at a base clock of 2325 MHz and reaches a boost clock of 2572 MHz, while its 6144 shading units contribute to a floating-point throughput of 31.6 TFLOPS. The card includes RGB lighting and supports up to four displays simultaneously.

On the memory side, the RTX 5070 Phoenix GS is equipped with 12GB of GDDR7 VRAM across a 192-bit bus, delivering an effective memory speed of 28000 MHz and a peak bandwidth of 672 GB/s. It supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3.0, ray tracing, and DLSS, alongside Intel Resizable BAR. Display connectivity consists of three DisplayPort outputs and one HDMI 2.1b port, with no USB-C or DVI connections present. The card has a rated TDP of 250W and uses a PCIe 5.0 interface, with dimensions of 331.9 mm in length and 133.1 mm in height.

Pros
  • Supports up to four simultaneous displays, offering flexible multi-monitor setups
  • GDDR7 memory with 672 GB/s of bandwidth enables fast data throughput for demanding workloads
  • Ray tracing and DLSS support extend rendering capabilities for compatible applications
  • ECC memory support adds a layer of data reliability for error-sensitive tasks
  • RGB lighting is built in, allowing for visual customization without additional hardware
  • Intel Resizable BAR is included, allowing the CPU broader access to GPU memory
Cons
  • The 192-bit memory bus is narrower than what some higher-tier cards in this category offer, which can limit memory throughput scaling
  • At 331.9 mm in length, the card requires a sufficiently large case to fit properly
  • No USB-C display output is available, which may limit compatibility with certain modern monitors
  • Air-water hybrid cooling is not supported, so thermal management relies entirely on the air cooling solution provided
Who is this for?

This card is well-suited to users who work with ray tracing and DLSS-enabled applications, where the combination of 6144 shading units, 31.6 TFLOPS of compute throughput, and hardware-accelerated ray tracing can be put to consistent use. The 12GB of GDDR7 VRAM paired with 672 GB/s of bandwidth makes it a reasonable fit for high-resolution texture workloads and content creation tasks that benefit from fast memory access. Users who need to drive multi-monitor setups of up to four displays will also find the output configuration practical, and ECC memory support adds relevance for those running applications sensitive to memory errors.

Who is this NOT for?

Users who rely heavily on large VRAM capacity for tasks such as running extensive AI models or working with very high-resolution assets across multiple streams may find 12GB limiting over time. The card's 250W TDP and reliance on air cooling alone means it is less suited to thermally constrained builds or compact cases where heat dissipation is a concern, particularly given its 331.9 mm length. Those who require USB-C display connectivity or DVI outputs for legacy monitors will also find this card's port selection incompatible with their setup without additional adapters.

Final Verdict

The Gainward GeForce RTX 5070 Phoenix GS is a well-specified graphics card built on the Blackwell architecture, bringing together a meaningful set of features for users who want ray tracing, DLSS support, and multi-display capability in a single card. Its 12GB of GDDR7 VRAM with 672 GB/s of bandwidth positions it comfortably for high-resolution workloads and content creation pipelines, while ECC memory support adds a degree of reliability that extends its relevance beyond purely gaming contexts. The 250W TDP and air-only cooling do place real demands on the build environment, and the 192-bit bus width and VRAM capacity set a ceiling for the most memory-intensive tasks. Taken as a whole, the RTX 5070 Phoenix GS is a capable card for users whose workloads align with its feature set, provided their system can accommodate its physical and thermal requirements.
