Palit GeForce RTX 4070 Super Infinity 3 OC

Manufacturer: Palit

The Palit GeForce RTX 4070 Super Infinity 3 OC is a graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process with 35,800 million transistors. It operates at a base clock of 1980 MHz, reaching a boost clock of 2640 MHz, and delivers 37.85 TFLOPS of floating-point performance across its 7168 shading units.

On the memory side, the card carries 12GB of GDDR6X across a 192-bit bus, with an effective speed of 21,000 MHz and a peak bandwidth of 504 GB/s. It supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, and DLSS, and connects to up to four displays via one HDMI 2.1a port and three DisplayPort outputs. The card has a rated TDP of 245W and dimensions of 294 mm by 116 mm.

Pros
  • Boost clock reaches 2640 MHz, offering a high operating frequency for demanding rendering tasks
  • 37.85 TFLOPS of floating-point performance supported by 7168 shading units gives this card substantial compute throughput
  • 12GB of GDDR6X memory running at 21,000 MHz effective speed with 504 GB/s bandwidth suits memory-intensive workloads well
  • Supports ray tracing and DLSS, enabling more advanced rendering techniques in compatible applications
  • Four simultaneous display outputs via one HDMI 2.1a and three DisplayPort connections provide flexible multi-monitor setups
  • ECC memory support adds data integrity protection useful for compute-oriented use cases
Cons
  • 192-bit memory bus width is narrower than what some cards in this category offer, which can limit memory throughput scaling
  • 245W TDP places notable demands on system power delivery and cooling capacity
  • No USB-C output limits connectivity options for users with displays or devices that rely on that interface
  • Air-water cooling is not supported, restricting thermal management to the card's built-in air cooling solution
  • No RGB lighting for users who factor visual customization into their build aesthetics
Who is this for?

This card is well-suited to users who engage in demanding 3D rendering and gaming workloads, where the combination of 37.85 TFLOPS, 7168 shading units, and a 2640 MHz boost clock can handle complex scenes with relative ease. The 12GB of GDDR6X memory with 504 GB/s bandwidth makes it a reasonable fit for content creators working with high-resolution textures or GPU-accelerated compute tasks, while ECC memory support adds reliability for those running precision-sensitive workloads. Users who need multi-monitor setups of up to four displays will also find the output configuration — one HDMI 2.1a and three DisplayPort connections — practical for productivity or simulation environments.

Who is this NOT for?

Users working in environments with strict power constraints may find the 245W TDP problematic, as it requires a well-specced power supply and adequate case airflow, and the absence of air-water cooling support limits thermal headroom in tightly configured builds. The 192-bit memory bus may also fall short for workloads that push very high memory bandwidth demands simultaneously, making this card a less ideal fit for large-scale machine learning tasks or professional visualization pipelines that benefit from wider bus configurations. Additionally, users who rely on USB-C display connectivity will need to look elsewhere, as no such output is present on this card.
