It supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, alongside Intel Resizable BAR. Display output consists of two HDMI 2.1b ports and three DisplayPort connections, supporting up to four displays simultaneously. The card connects via PCIe 5 and supports ECC memory.

Pros

Supports up to four displays simultaneously with five total video outputs across two HDMI 2.1b and three DisplayPort connections
DLSS and ray tracing support are both present, enabling advanced rendering features
12GB of GDDR7 VRAM on a 192-bit bus delivers 672 GB/s of memory bandwidth
ECC memory support adds data integrity for error-sensitive workloads
Intel Resizable BAR is supported, allowing the CPU to access the full GPU frame buffer
RGB lighting is included for users who want a visually customizable build

Cons

No USB-C, DVI, or mini DisplayPort outputs available
Air-water cooling is not supported, limiting cooling flexibility
192-bit memory bus width is narrower than what some cards in this performance tier offer
A 250W TDP places notable power demands on the system and may require a capable PSU

Who is this for?

This card is well-suited to users who need substantial rendering throughput, given its 32.07 TFLOPS of floating-point performance and 6,144 shading units. The combination of ray tracing support, DLSS, and DirectX 12 Ultimate makes it a practical choice for demanding real-time rendering workloads. Its five video outputs and multi-display support for up to four screens also make it a strong fit for users who rely on expanded desktop setups, whether for content creation, simulation, or intensive multitasking workflows. ECC memory support extends its relevance to users with error-sensitive compute tasks.

Who is this NOT for?

Users working in compact or small-form-factor builds may find the 329 mm length and 140 mm height a limiting factor, as the card's physical dimensions require a spacious enclosure. The 250W TDP also makes it a poor match for systems with modest power supplies or those where energy efficiency is a priority. Additionally, users who require USB-C video output or legacy DVI connectivity will find no support for either on this card, which could pose integration challenges in certain display setups.
