Galax GeForce RTX 4070 Super 1-Click OC 2X

Manufacturer: Galax

The Galax GeForce RTX 4070 Super 1-Click OC 2X is a graphics card from Galax based on NVIDIA's Ada Lovelace architecture, manufactured using a 5 nm process. The card ships with a factory overclock, reaching a base clock of 1980 MHz and a turbo clock of 2475 MHz, and includes RGB lighting along with support for up to four simultaneous displays.

On the memory side, the card is equipped with 12GB of GDDR6X VRAM running at an effective speed of 21000 MHz across a 192-bit bus, delivering up to 504 GB/s of bandwidth. It offers 7168 shading units, 224 texture mapping units, and 80 render output units, translating to a floating-point throughput of 35.48 TFLOPS. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, and Intel Resizable BAR, with connectivity provided through one HDMI 2.1a port and three DisplayPort outputs. The card has a rated TDP of 220W and measures 252 mm in length and 131 mm in height.

Pros
  • Supports ray tracing and DLSS, enabling more advanced rendering options in compatible applications
  • ECC memory support adds a degree of data integrity for workloads sensitive to memory errors
  • Three DisplayPort outputs alongside an HDMI 2.1a port allow up to four displays to be connected simultaneously
  • Double Precision Floating Point (DPFP) support extends the card's suitability beyond typical graphics tasks to compute workloads requiring 64-bit precision
  • The 5 nm fabrication process and 35,800 million transistors reflect a modern, dense chip design
  • RGB lighting is present for users who prioritize visual customization of their build
Cons
  • The 192-bit memory bus width is narrower than what some cards in this segment offer, which limits maximum memory bandwidth headroom
  • No USB-C output is available, which may be a limitation for users with USB-C monitors or VR headsets that require it
  • No DVI or mini DisplayPort outputs are included, reducing compatibility with older display hardware
  • Air-water cooling is not supported, so users seeking liquid cooling integration will need to look elsewhere
  • A 220W TDP demands a capable power supply and adequate case airflow to maintain stable thermals
Who is this for?

This card is well suited to users who want to run graphically demanding applications with ray tracing and DLSS enabled, as both features are fully supported and can meaningfully affect visual output quality in compatible software. The availability of ECC memory and Double Precision Floating Point support also makes it a reasonable fit for users who occasionally run compute or data-integrity-sensitive workloads alongside their primary graphics tasks. Those who use multiple monitors will appreciate the four-display output capability, and users who enjoy personalizing their system aesthetics will find the onboard RGB lighting a welcome addition.

Who is this NOT for?

Users who rely heavily on USB-C or legacy display connections such as DVI will find the port selection limiting, as neither is available on this card. The 220W TDP means it is not a good fit for small form factor or low-airflow builds where thermal headroom is restricted, as adequate cooling and power delivery are necessary to maintain stable operation. Additionally, users who require liquid cooling integration will need to look elsewhere, since air-water cooling is not supported by this model.
