On the memory side, the card carries 16GB of GDDR7 VRAM across a 256-bit bus, with an effective memory speed of 30,000 MHz and a maximum bandwidth of 960 GB/s. It delivers 56.28 TFLOPS of floating-point performance and includes Double Precision Floating Point support. Feature-wise, it is compatible with DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3.0, and supports ray tracing, DLSS, stereoscopic 3D, and multi-display configurations across up to four screens. Connectivity includes three DisplayPort outputs and one HDMI 2.1b port, with no USB-C or DVI options available. The card has a thermal design power of 360W, measures 316.5mm in length and 139mm in height, and relies solely on air cooling.

Pros
  • Supports up to four simultaneous displays, offering flexibility for multi-monitor setups
  • ECC memory support adds a layer of data integrity for workloads where memory accuracy matters
  • DLSS and ray tracing support are both present, enabling advanced rendering features in compatible applications
  • Intel Resizable BAR is supported, allowing the CPU to access the full GPU frame buffer for potentially smoother data transfers
  • The card includes RGB lighting, giving users control over its visual appearance
  • Double Precision Floating Point support broadens its usability beyond graphics to compute-intensive tasks
Cons
  • A 360W TDP places significant demand on the power supply, requiring careful system planning
  • The card measures 316.5mm in length, which may not fit in smaller or compact PC enclosures
  • No USB-C output is available, limiting direct connectivity to USB-C monitors or devices
  • Water cooling is not supported, restricting thermal management to air cooling alone
  • Only a single HDMI port is provided, which may be limiting for users who rely on multiple HDMI connections
Who is this for?

This card is well-suited for users running demanding graphics workloads across multiple displays, given its support for up to four simultaneous outputs and a broad feature set that includes ray tracing and DLSS. Its Double Precision Floating Point capability and ECC memory support also make it a reasonable fit for those engaged in GPU-accelerated compute tasks such as simulation or data processing alongside visual work. Users with full-sized ATX or extended ATX builds and robust power supplies will be able to accommodate its 360W TDP and 316.5mm length without difficulty.

Who is this NOT for?

Users working within compact or small form factor systems are likely to find this card impractical, as its 316.5mm length and 360W thermal design power demand substantial physical space and a high-capacity power delivery setup. Those who depend on USB-C display connectivity or require multiple HDMI outputs will also find the port configuration limiting, since the card offers no USB-C outputs and only a single HDMI port. Additionally, users seeking a quieter or more thermally flexible setup may be constrained by the absence of water-cooling support, as thermal management is restricted to air cooling only.
