Galax GeForce RTX 4080 Super ST 1-Click OC

Manufacturer: Galax

The Galax GeForce RTX 4080 Super ST 1-Click OC is a desktop graphics card built on NVIDIA's Ada Lovelace architecture, produced using a 5 nm manufacturing process and integrating 45,900 million transistors. It ships with a factory overclock and a one-click overclocking feature, with the GPU operating at a base clock of 2295 MHz and a boost clock of 2550 MHz. The card measures 352 mm in width and 153 mm in height, so case clearance is something to verify before installation, and it includes RGB lighting for visual customization within a build.

Memory configuration consists of 16GB of GDDR6X on a 256-bit bus, running at an effective speed of 23,000 MHz to deliver a maximum bandwidth of 736.3 GB/s, with ECC memory support also present. The compute side delivers 52.22 TFLOPS of floating-point performance alongside a texture rate of 816 GTexels/s and a pixel rate of 285.6 GPixel/s, backed by 10,240 shading units, 320 TMUs, and 112 ROPs. Double Precision Floating Point is supported, and the feature set covers DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, and Intel Resizable BAR. Display output is handled by one HDMI 2.1a port and three DisplayPort connections, supporting up to four monitors simultaneously, with the card drawing up to 320W over a PCIe 4.0 interface.

Pros
  • 16GB of GDDR6X memory on a 256-bit bus with an effective speed of 23,000 MHz delivers 736.3 GB/s of bandwidth, supporting sustained throughput in memory-heavy rendering and compute tasks
  • Floating-point performance of 52.22 TFLOPS combined with DPFP support makes the card capable of handling both graphics and precision compute workloads
  • Ray tracing and DLSS are both supported, enabling access to two widely adopted modern rendering technologies in compatible applications
  • ECC memory support provides error detection and correction, adding reliability for compute-sensitive use cases
  • Four display outputs — one HDMI 2.1a and three DisplayPort — allow multi-monitor configurations of up to four screens without additional hardware
  • RGB lighting is included, giving users the option to integrate the card into a visually customized build
Cons
  • A 320W TDP places significant demands on system power delivery and requires adequate case airflow to maintain stable operation
  • At 352 mm in length and 153 mm in height, the card's physical size requires careful case compatibility checks before installation
  • No USB-C video output is available, which limits connectivity for users relying on USB-C monitors
  • Air-water hybrid cooling is absent, leaving thermal management entirely dependent on the card's air cooling setup
  • DVI and mini DisplayPort outputs are not present, restricting compatibility with older or specialized display hardware
Who is this for?

This card is well-suited to users who regularly work with compute-intensive or memory-heavy workloads, given its 52.22 TFLOPS of floating-point performance, DPFP support, and ECC memory — attributes that collectively benefit tasks where both throughput and data accuracy matter. The 16GB of GDDR6X memory delivering 736.3 GB/s of bandwidth makes it a practical choice for workflows involving large textures, high-resolution assets, or substantial data sets. Users who want to run ray tracing and DLSS in supported applications, or who need to manage up to four displays from a single card, will find the hardware ready for both without requiring additional adapters or accessories.

Who is this NOT for?

The card's 320W TDP and 352 mm length make it a poor fit for compact or modestly equipped builds, as both the power supply requirements and physical footprint demand a well-sized case and a capable power delivery setup. Users whose display workflow depends on USB-C video output will find no support for that interface here, which could necessitate workarounds that may not suit every setup. Additionally, those with older monitors that rely on DVI connectivity will have no direct output option, as that interface is absent from this card's port configuration.

Underpinning this card is the Ada Lovelace architecture, built on a 5 nm process with 45,900 million transistors packed into the die. It interfaces with the system over PCIe 4.0 and carries a thermal design power of 320W, which places meaningful demands on both the power supply and the case's airflow capacity. The physical dimensions come in at 352 mm in width and 153 mm in height, so confirming case clearance ahead of installation is advisable. Air-water hybrid cooling is not part of this card's design; thermal management is handled entirely through its air-based cooling solution.

Final Verdict

The Galax GeForce RTX 4080 Super ST 1-Click OC is a specification-rich graphics card that pairs 52.22 TFLOPS of compute throughput with 16GB of GDDR6X memory running at 736.3 GB/s of bandwidth, forming a foundation well-suited to demanding rendering, multi-display workflows, and precision compute tasks. Ray tracing, DLSS, ECC memory, and DPFP support extend its usefulness across both graphical and compute-oriented scenarios, while the one-click overclocking feature gives users a straightforward path to higher clock speeds. That said, its 320W TDP and 352 mm length mean it is best reserved for builds that can genuinely accommodate its power and space requirements. For users whose systems meet those prerequisites, the Galax GeForce RTX 4080 Super ST 1-Click OC represents a thoroughly capable and feature-complete option within the graphics card category.
