Galax GeForce RTX 5070 Ex 1-Click OC

Name: Galax GeForce RTX 5070 Ex 1-Click OC
Brand: Galax
SKU: 77655

Manufacturer: Galax

The Galax GeForce RTX 5070 Ex 1-Click OC is a desktop graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5 nm semiconductor process. It carries a factory boost clock of 2527 MHz alongside a base clock of 2325 MHz, and its 1-Click OC designation reflects an out-of-the-box overclocked configuration. With a TDP of 250W and dimensions of 252 mm × 131 mm, it sits in a form factor suited to a wide range of mid-to-full-tower builds using a PCIe 5.0 slot.

On the memory side, the card is equipped with 12GB of GDDR7 VRAM running across a 192-bit bus at an effective speed of 28,000 MHz, yielding a maximum bandwidth of 672 GB/s. Its 6,144 shading units, 192 texture mapping units, and 80 render output units produce a texture rate of 485.2 GTexels/s and a pixel fill rate of 202.2 GPixels/s, with floating-point performance rated at 31.05 TFLOPS. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, and Intel Resizable BAR, while display output is handled through one HDMI 2.1b port and three DisplayPort outputs, supporting up to four monitors simultaneously.

Pros

Supports up to four displays simultaneously, making it suitable for multi-monitor setups
GDDR7 memory with 672 GB/s of bandwidth enables fast data throughput for demanding workloads
ECC memory support adds a layer of data integrity for compute-oriented tasks
Hardware ray tracing and DLSS support are both present, covering two key rendering acceleration features
Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve data transfer efficiency
The 192-bit memory bus paired with 12GB of VRAM provides a solid balance of capacity and throughput for the memory configuration

Cons

No USB-C display output, limiting compatibility with monitors or devices that rely on that connection
Liquid or hybrid air-water cooling is not supported, so thermal management depends entirely on the card's air cooler
No RGB lighting for users who prefer illuminated builds
The 250W TDP places meaningful demands on system power delivery and case airflow
With no DVI or mini DisplayPort outputs, users with older display hardware may need adapters

Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, given its 31.05 TFLOPS of floating-point performance, ECC memory support, and DPFP capability. Gamers and content creators who rely on ray tracing and DLSS will find both features natively supported, while those managing multi-monitor setups can take advantage of four simultaneous display outputs across three DisplayPort and one HDMI 2.1b connection. The 672 GB/s memory bandwidth and 12GB of GDDR7 VRAM also make it a reasonable fit for workloads that require fast, high-capacity frame buffer access.

Who is this NOT for?

Users looking for a card with USB-C display connectivity or legacy DVI output will find this card lacking, as neither interface is present, potentially requiring adapters for certain monitor configurations. The 250W TDP means the card is not well-suited to compact or low-airflow builds where power delivery and thermal headroom are limited. Additionally, users who prioritize hybrid or liquid cooling solutions for sustained silent operation will need to look elsewhere, since the card ships with air cooling only and offers no support for water-cooling configurations.
