It supports DirectX 12, OpenGL 4.6, ray tracing, and AMD FSR4, and connects via PCIe 5.0. Display output options include one HDMI 2.1b port and three DisplayPort outputs, supporting up to four monitors simultaneously. The card has a TDP of 304W and measures 352 mm in length by 149 mm in height.

Pros
  • A turbo clock of 3060 MHz and 50.14 TFLOPS of floating-point performance indicate substantial computational headroom for demanding graphics tasks
  • 16GB of GDDR6 VRAM across a 256-bit bus with 644.6 GB/s of bandwidth supports memory-intensive workloads and high-resolution rendering
  • Support for ray tracing and AMD FSR4 enables advanced visual effects alongside upscaling capabilities
  • ECC memory support adds a layer of data integrity useful in compute and professional workloads
  • Up to four simultaneous displays can be connected using the three DisplayPort outputs and one HDMI 2.1b port
  • PCIe 5.0 connectivity ensures the card is compatible with current-generation motherboard interfaces
Cons
  • A TDP of 304W places notable demands on system power delivery and cooling infrastructure
  • The card measures 352 mm in length, which may not fit in smaller or compact PC cases
  • DLSS and XeSS upscaling technologies are not supported, limiting upscaling options to AMD FSR4 only
  • No USB-C output is available, restricting compatibility with displays or devices that rely on that connection
  • Air-water cooling is not included, meaning thermal management depends entirely on the installed air cooler configuration
Who is this for?

This card is well-suited to users running high-resolution gaming or compute-heavy workloads that benefit from 16GB of GDDR6 VRAM, 644.6 GB/s of memory bandwidth, and 50.14 TFLOPS of floating-point performance. The inclusion of ray tracing, AMD FSR4, and support for up to four simultaneous displays makes it a strong fit for users who work across multi-monitor setups or need advanced visual rendering capabilities. ECC memory support also makes it relevant for users with reliability requirements in GPU-accelerated compute tasks.

Who is this NOT for?

At 352 mm in length and with a 304W TDP, this card is not a practical choice for users with compact or small-form-factor builds that have limited physical space or constrained power delivery. Users who rely on DLSS or XeSS upscaling technologies will find those options absent, making it a poor match for workflows or gaming setups built around those specific pipelines. Additionally, the lack of a USB-C output means it is unsuitable for users who depend on that connection type for modern displays or devices.
