Galax GeForce RTX 5080 Metal Master Platinum Edition OC

Manufacturer: Galax

The Galax GeForce RTX 5080 Metal Master Platinum Edition OC is a high-end graphics card from Galax, based on NVIDIA's Blackwell architecture and manufactured on a 5 nm process with 45,600 million transistors. It ships with 16GB of GDDR7 memory running across a 256-bit bus, delivering a peak bandwidth of 960 GB/s, and the card supports Intel Resizable BAR alongside RGB lighting on its Metal Master cooling shroud.

Clocked at a base of 2295 MHz with a turbo frequency reaching 2655 MHz, the RTX 5080 Metal Master Platinum Edition OC provides 57.09 TFLOPS of floating-point performance and a texture rate of 892.1 GTexels/s across its 10,752 shading units and 336 texture mapping units. Display output is handled through one HDMI 2.1b port and three DisplayPort connections for a total of four supported displays, while feature support includes DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and a 360W TDP within a card measuring 316.5 mm in length and 139 mm in height.

Pros
  • Supports up to four displays simultaneously through three DisplayPort and one HDMI 2.1b output, offering flexible multi-monitor setups
  • 960 GB/s memory bandwidth across a 256-bit bus with GDDR7 VRAM provides substantial throughput for demanding workloads
  • ECC memory support adds data integrity for compute-sensitive tasks
  • Ray tracing and DLSS are both supported, expanding rendering capability options
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve data transfer efficiency
  • RGB lighting is included, allowing visual customization of the card within a build
Cons
  • A 360W TDP places significant demands on system power delivery and case airflow
  • No air-water cooling option is available, leaving thermal management entirely dependent on the card's air cooler
  • The 316.5 mm length may pose fitment challenges in smaller or mid-tower cases
  • No USB-C, DVI, or mini DisplayPort outputs limits compatibility with certain older or specialized display hardware
Who is this for?

This card is well-suited to users who work with demanding rendering and compute workloads, given its 57.09 TFLOPS of floating-point performance, ECC memory support, and Double Precision Floating Point capability. Enthusiasts running ray-traced titles with DLSS enabled will benefit from the combination of hardware-accelerated ray tracing and AI-driven upscaling. The four-display output support also makes it a practical fit for users who require expansive multi-monitor configurations, whether for content creation, simulation, or productivity-intensive environments.

Who is this NOT for?

The card's 360W TDP makes it a poor match for users with modest or older power supplies and cases with limited airflow, as the thermal and electrical demands are substantial. Its 316.5 mm length means it is not well-suited for compact or small-form-factor builds where physical clearance is restricted. Users who rely on DVI or USB-C display connections will also find this card lacking, as neither output type is available on this model.
