AX Gaming Rebel GeForce RTX 5080 X3W Max

Manufacturer: AX Gaming

The AX Gaming Rebel GeForce RTX 5080 X3W Max is a high-specification graphics card drawing on Nvidia's Blackwell architecture, manufactured on a 5 nm process with 45,600 million transistors. It ships with 16GB of GDDR7 video memory across a 256-bit bus, delivering a maximum memory bandwidth of 960 GB/s at an effective memory speed of 30,000 MHz. The card supports ray tracing, DLSS, and DirectX 12 Ultimate, and includes RGB lighting along with support for up to four simultaneous displays.

On the performance side, the AX Gaming Rebel GeForce RTX 5080 X3W Max runs a base GPU clock of 2,295 MHz with a turbo frequency reaching 2,670 MHz, translating to 57.42 TFLOPS of floating-point throughput and a texture rate of 897.1 GTexels/s. Its 10,752 shading units are paired with 336 texture mapping units and 112 render output units. The card connects via PCIe 5.0 and offers one HDMI 2.1b port alongside three DisplayPort outputs. With a TDP of 360W and dimensions of 358 mm by 148 mm, it is a substantial triple-slot design intended for full-size desktop builds.

Pros
  • With 16GB of GDDR7 memory running at an effective 30,000 MHz and 960 GB/s of bandwidth, the card handles large textures and memory-intensive workloads without running short on VRAM
  • Support for ray tracing and DLSS broadens rendering options for compatible applications and games
  • Four simultaneous display outputs — three DisplayPort and one HDMI 2.1b — offer flexible multi-monitor configurations
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve data transfer efficiency
  • ECC memory support adds a layer of data integrity useful in compute or professional workloads
  • RGB lighting provides visual customization for builds where aesthetics matter
Cons
  • A 360W TDP places significant demand on the power supply, requiring a well-specified system to operate reliably
  • The card's dimensions of 358 mm in width and 148 mm in height mean it will not fit in smaller or compact desktop enclosures
  • No USB-C video output is available, limiting connectivity options for monitors or displays that rely on that interface
  • Air-water cooling is not included, so users requiring liquid cooling would need to source a third-party solution separately
Who is this for?

This card is well-matched to users who run demanding rendering and compute workloads that benefit from 16GB of GDDR7 memory, 960 GB/s of bandwidth, and Double Precision Floating Point support. It also suits those who want to drive up to four displays simultaneously via a combination of three DisplayPort and one HDMI 2.1b output, making it a practical choice for multi-monitor desktop setups. Users with full-size desktop builds and robust power supplies will be best positioned to take full advantage of its PCIe 5.0 interface, ray tracing support, and DLSS capability.

Who is this NOT for?

The card's 360W TDP makes it unsuitable for systems with modest or underpowered PSUs, and its 358 mm length rules it out for compact or small-form-factor builds where physical clearance is limited. Users who rely on USB-C display connectivity will find no support for that interface here, and those looking for a liquid cooling option out of the box will need to look elsewhere, as no air-water cooling solution is included with this card.
