It supports DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, alongside ray tracing and DLSS. Connectivity is handled through three DisplayPort outputs and one HDMI 2.1b port, with Intel Resizable BAR support rounding out the feature set. The card measures 300mm in length and 120mm in height, using air cooling in its thermal solution.

Pros

With 10,752 shading units and 56.77 TFLOPS of floating-point performance, the card is well-suited for demanding rendering and compute workloads
The 16GB of GDDR7 VRAM running at 30,000 MHz effective speed and delivering 960 GB/s of bandwidth provides substantial headroom for high-resolution textures and large datasets
Support for ray tracing and DLSS together enables more realistic lighting in compatible titles while maintaining playable frame rates
Four simultaneous display outputs — three DisplayPort and one HDMI 2.1b — offer flexible multi-monitor setups without additional adapters
Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve frame delivery in compatible systems
ECC memory support adds data integrity protection, making the card more suitable for workloads where memory accuracy matters

Cons

A 360W TDP places significant demand on the power supply, requiring a well-specced system to operate reliably
The card does not support water cooling, which may limit thermal headroom in compact or thermally constrained builds
At 300mm in length, installation could be restricted in smaller chassis that do not accommodate full-length cards
The absence of USB-C output limits direct connectivity with certain modern monitors and portable displays that rely on that interface

Who is this for?

This card is well-matched for users running demanding rendering, 3D visualization, or GPU compute workloads that can take advantage of 56.77 TFLOPS of floating-point performance, ECC memory support, and Double Precision Floating Point capability. Content creators and developers working with large assets will benefit from the 16GB of GDDR7 VRAM and 960 GB/s of memory bandwidth, which provides substantial throughput for high-resolution workflows. The four-display output support and DLSS capability also make it a practical fit for users who need a wide desktop spread or want to leverage AI-assisted rendering in compatible applications.

Who is this NOT for?

Users working within compact or small-form-factor builds may find the card's 300mm length and 360W TDP difficult to accommodate, as both place real constraints on case clearance and power supply requirements. The absence of water cooling support further limits its suitability for thermally restricted environments where heat dissipation is a concern. Additionally, users who rely on USB-C display connectivity or those seeking a card with minimal power draw for a quieter, low-energy system will find this configuration a poor match for their needs.
