Galax GeForce RTX 5070 Ex Gamer 1-Click OC

Manufacturer: Galax

The Galax GeForce RTX 5070 Ex Gamer 1-Click OC is a desktop graphics card from Galax based on NVIDIA's Blackwell architecture, manufactured on a 5 nm process with 31,100 million transistors. It ships with a factory-tuned 1-Click OC profile that sets the base GPU clock at 2325 MHz and allows the card to boost up to 2557 MHz under load, alongside integrated RGB lighting for system builders who want a visual element to their build.

On the memory side, the card carries 12 GB of GDDR7 VRAM across a 192-bit bus, reaching an effective speed of 28,000 MHz and a peak bandwidth of 672 GB/s. The 6144 shading units, 192 TMUs, and 80 ROPs contribute to a texture rate of 490.9 GTexels/s and a floating-point throughput of 31.42 TFLOPS, while hardware ray tracing and DLSS support are included. Display output is handled by one HDMI 2.1b port and three DisplayPort outputs, supporting up to four monitors simultaneously, and the card connects via PCIe 5.0 within a 334 × 144 mm form factor at a rated TDP of 250W.

Pros
  • Supports up to four displays simultaneously, making it practical for multi-monitor setups
  • Includes hardware ray tracing and DLSS support, broadening its rendering capabilities
  • ECC memory support helps maintain data integrity during operation
  • Intel Resizable BAR compatibility allows the CPU to access the full VRAM pool more efficiently
  • RGB lighting is built in for users who want a visually customized build
  • No LHR restrictions, meaning the full compute throughput is accessible without limitations
Cons
  • The 192-bit memory bus is narrower than what some cards in this class offer, limiting memory bandwidth scaling
  • No USB-C output is available, which may be a limitation for users with USB-C monitors or VR headsets
  • Air-water cooling is not supported, so users cannot connect the card to a custom liquid cooling loop
  • At 334 mm in length, the card requires a sufficiently large case to fit properly
  • Only one HDMI port is provided, which may be restrictive for users relying on multiple HDMI-connected devices
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads that benefit from 31.42 TFLOPS of floating-point throughput, 12 GB of GDDR7 VRAM, and Double Precision Floating Point support. Content creators and developers working with GPU-accelerated applications will find the OpenCL 3 and DirectX 12 Ultimate support practical, while the ability to drive up to four displays simultaneously makes it a strong fit for multi-monitor productivity setups. The inclusion of DLSS and hardware ray tracing also makes it relevant for users engaged in graphically intensive real-time rendering scenarios.

Who is this NOT for?

Users working inside compact or small-form-factor cases may find the 334 mm length a physical constraint, as the card demands a chassis with adequate clearance. Those who rely on USB-C display connectivity or need multiple HDMI outputs will be limited by the single HDMI 2.1b port and the complete absence of USB-C outputs. Additionally, users looking to integrate the card into a custom liquid cooling loop will find this option unavailable, since the card does not support air-water cooling configurations.
