On the memory side, the card carries 16GB of GDDR6X across a 256-bit bus, reaching an effective speed of 23,000 MHz and delivering a maximum bandwidth of 736.3 GB/s, with ECC memory support included. Compute performance is rated at 52.22 TFLOPS, alongside a texture rate of 816 GTexels/s and a pixel rate of 285.6 GPixels/s, backed by 10,240 shading units, 320 TMUs, and 112 ROPs. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, and can drive up to four displays simultaneously through one HDMI 2.1a port and three DisplayPort outputs. It connects via PCIe 4.0 and supports Intel Resizable BAR.

Pros

Boost clock of 2550 MHz combined with 52.22 TFLOPS of floating-point performance indicates substantial compute throughput for demanding graphical workloads
16GB of GDDR6X memory running at an effective 23,000 MHz delivers 736.3 GB/s of bandwidth, which suits memory-intensive rendering and large asset workloads
Four display outputs — one HDMI 2.1a and three DisplayPort — allow multi-monitor setups without additional hardware
Ray tracing and DLSS support are both present, enabling access to two significant modern rendering features
ECC memory support adds a layer of data integrity protection useful in compute-sensitive tasks
RGB lighting is included for users who want visual customization within their build

Cons

A 320W TDP places considerable demands on system power delivery and case airflow planning
At 352 mm in length and 153 mm in height, the card requires careful verification of case clearance before installation
No USB-C video output is available, which may be limiting for users with USB-C monitors
Air-water hybrid cooling is not included, leaving thermal management entirely dependent on the card's air cooling solution
No DVI or mini DisplayPort outputs are present, restricting compatibility with older display hardware

Who is this for?

This card is well-suited to users who work with demanding 3D rendering, simulation, or compute workloads, given its 52.22 TFLOPS of floating-point performance, DPFP support, and ECC memory — attributes that directly benefit precision-dependent tasks. The 16GB of GDDR6X memory with 736.3 GB/s of bandwidth also makes it a strong fit for workflows involving large textures or high-resolution assets. Additionally, users who want to run multi-monitor setups of up to four displays will find the port configuration — one HDMI 2.1a and three DisplayPort outputs — covers that need without extra adapters. Those who take advantage of ray tracing and DLSS in supported applications will also find the hardware ready for those features out of the box.

Who is this NOT for?

Users working in space-constrained builds may find the 352 mm length and 153 mm height a genuine obstacle, as not all mid-tower or compact cases can accommodate a card of this physical footprint. The 320W TDP also makes this card poorly suited to systems with modest power supplies or limited airflow, since the thermal and power demands require a well-equipped setup to operate reliably. Furthermore, users who depend on USB-C video output or legacy DVI connectivity will find no support for either on this card, making it a poor match for workflows tied to those interfaces.
