Galax GeForce RTX 5070 Ti Magic Blade OC

Manufacturer: Galax

The Galax GeForce RTX 5070 Ti Magic Blade OC is a graphics card from Galax based on NVIDIA's Blackwell architecture, manufactured on a 5 nm process with 45,600 million transistors. It runs at a base clock of 2295 MHz and reaches a boosted speed of 2497 MHz under load, delivering 44.75 TFLOPS of floating-point performance and a texture rate of 699.2 GTexels/s. The card also features RGB lighting and supports up to four displays simultaneously.

On the memory side, the card is equipped with 16GB of GDDR7 across a 256-bit bus, achieving an effective memory speed of 28,000 MHz and a maximum bandwidth of 896 GB/s, with ECC memory support included. Connectivity options include one HDMI 2.1b port and three DisplayPort outputs, while USB-C output is absent. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, and Intel Resizable BAR, with a 300W TDP and dimensions of 316.5 mm in length and 140.1 mm in height.

Pros
  • Supports up to four displays simultaneously, offering flexibility for multi-monitor setups
  • GDDR7 memory with 896 GB/s bandwidth and ECC support ensures both high throughput and data integrity during demanding workloads
  • The combination of ray tracing and DLSS support enables more realistic rendering alongside performance-recovery capabilities
  • HDMI 2.1b and three DisplayPort outputs cover a wide range of modern display connectivity needs
  • RGB lighting is built into the card for users who want visual customization within their build
  • Intel Resizable BAR support allows the CPU broader access to VRAM, which can benefit certain workloads
Cons
  • A 300W TDP places significant power demands on the system, requiring a suitably rated power supply
  • The card lacks USB-C output, limiting compatibility with certain modern displays and adapters that rely on that connector
  • Air-water cooling is not included, meaning thermal management depends entirely on whatever cooling solution comes pre-fitted
  • At 316.5 mm in length, the card may not fit in all mid-tower or smaller PC cases without careful clearance checks
Who is this for?

This card is well-suited to users who work with demanding real-time rendering workloads, including those who rely on ray tracing and DLSS to balance visual fidelity with frame output. The 16GB of GDDR7 memory with ECC support also makes it a reasonable fit for compute-intensive tasks such as simulation or content creation workflows that benefit from high memory bandwidth and error-corrected data. Additionally, users looking to drive multi-monitor setups of up to four displays will find the port configuration practical, especially with HDMI 2.1b and three DisplayPort outputs covering a wide range of modern screens.

Who is this NOT for?

Users working within compact or small-form-factor builds may find the card's 316.5 mm length a physical obstacle, as it requires ample case clearance that smaller enclosures often cannot provide. The 300W TDP also makes this a poor fit for systems with modest power supplies or limited airflow, since the thermal demands are substantial and no air-water cooling solution is included. Additionally, users who rely on USB-C display output — such as those connecting to certain professional monitors or portable displays — will find that connector absent from this card's port configuration.
