AX Gaming Rebel GeForce RTX 4080 Super X3W Max

Manufacturer: AX Gaming

The AX Gaming Rebel GeForce RTX 4080 Super X3W Max is a high-end graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process and housing 45,900 million transistors. It operates with a base GPU clock of 2295 MHz and a boost frequency of 2580 MHz, while its 10,240 shading units contribute to a floating-point performance of 52.84 TFLOPS. The card also features RGB lighting and supports up to four displays simultaneously.

On the memory side, the card is equipped with 16GB of GDDR6X running across a 256-bit bus at an effective speed of 23,000 MHz, delivering a maximum bandwidth of 736.3 GB/s. It supports DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, along with ray tracing and DLSS. Connectivity is handled through one HDMI 2.1 port and three DisplayPort outputs, and the card carries a thermal design power rating of 320W with a physical footprint of 352 mm in length and 140 mm in height.

Pros
  • With 16GB of GDDR6X VRAM on a 256-bit bus, the card handles large textures and memory-intensive workloads without running short on video memory
  • Support for ray tracing and DLSS gives the card access to two significant rendering technologies for improved visual fidelity and frame rate optimization
  • The four-display output capability, backed by three DisplayPort and one HDMI 2.1 port, makes multi-monitor setups straightforward to configure
  • ECC memory support adds a useful layer of data integrity for compute-oriented tasks where memory accuracy matters
  • RGB lighting is built in, giving users some degree of visual customization without needing additional hardware
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can improve data throughput in compatible systems
Cons
  • A 320W TDP places considerable demands on the power supply, requiring a well-specced PSU and good case airflow
  • At 352 mm in length, the card may not fit in smaller or mid-tower cases without careful clearance checks
  • There are no USB-C or DVI outputs, which limits compatibility with certain older displays or devices that rely on those connections
  • Air-water cooling is not included, meaning thermal management depends entirely on the card's air cooling solution
  • The absence of XeSS (XMX) support restricts upscaling options to DLSS only, with no alternative upscaling path available
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads that benefit from 52.84 TFLOPS of floating-point performance, 16GB of GDDR6X VRAM, and ECC memory support. Its ray tracing and DLSS capabilities make it a strong fit for those working in visually intensive real-time environments where image quality and frame stability are priorities. The four-display output support also makes it a practical choice for users who need a wide multi-monitor setup for productivity or simulation work.

Who is this NOT for?

At 352 mm in length and with a 320W TDP, this card is not a good match for users working with compact or small-form-factor cases where space and power headroom are limited. The absence of USB-C and DVI outputs makes it a poor fit for users who rely on older display hardware or devices requiring those connection types. Additionally, since cooling is handled entirely through air, users in environments with restricted airflow or high ambient temperatures may find thermal management more challenging with this card.

Physically, it measures 352 mm in width and 140 mm in height, which is worth considering when checking chassis compatibility.

Final Verdict

The AX Gaming Rebel GeForce RTX 4080 Super X3W Max is a capable, specification-dense graphics card built on the Ada Lovelace architecture, offering a compelling combination of 52.84 TFLOPS of floating-point performance and 16GB of GDDR6X VRAM with ECC support — a pairing that makes it well-positioned for both graphically intensive and compute-oriented workloads. Ray tracing, DLSS, and four-display output round out a feature set that covers a wide range of professional and enthusiast use cases. That said, its 320W TDP and 352 mm length mean it demands a well-equipped system to operate at its best, and the absence of USB-C or DVI connectivity narrows its compatibility in certain setups. For users who can accommodate its physical and power requirements, this card delivers a thorough and coherent specification package.
