Palit GeForce RTX 4070 Super JetStream OC

Manufacturer: Palit

The Palit GeForce RTX 4070 Super JetStream OC is a desktop graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process and housing 35,800 million transistors. It ships with 12GB of GDDR6X video memory across a 192-bit bus, delivering a maximum memory bandwidth of 504 GB/s at an effective memory speed of 21,000 MHz. The card supports ray tracing, DLSS, and DirectX 12 Ultimate, and includes RGB lighting along with Intel Resizable BAR support.

On the performance side, the Palit RTX 4070 Super JetStream OC runs at a base GPU clock of 1,980 MHz with a boost clock of 2,640 MHz, yielding 37.85 TFLOPS of floating-point throughput. Its 7,168 shading units are complemented by 224 texture mapping units and 80 render output units, producing a texture rate of 591.4 GTexels/s and a pixel rate of 211.2 GPixels/s. The card carries a TDP of 245W, connects via PCIe 4.0, measures 328.9 mm in length and 130.5 mm in height, and provides one HDMI 2.1a port alongside three DisplayPort outputs for a maximum of four simultaneous displays.

Pros
  • Supports up to four simultaneous displays through three DisplayPort outputs and one HDMI 2.1a port, offering flexible multi-monitor setups
  • 12GB of GDDR6X memory with a 504 GB/s bandwidth ceiling provides substantial headroom for memory-intensive workloads
  • Ray tracing and DLSS are both supported, expanding compatibility with modern rendering techniques
  • ECC memory support adds a layer of data integrity useful in compute-oriented tasks
  • Intel Resizable BAR support allows the CPU to access the full GPU memory pool, which can benefit certain workloads
  • RGB lighting is built in, giving users control over the card's visual appearance without requiring add-ons
Cons
  • A TDP of 245W places notable demands on system power delivery and case airflow
  • The 192-bit memory bus is narrower than what some cards in this category offer, which can limit memory bandwidth scaling
  • Water cooling is not supported, so thermal management depends entirely on the air cooler configuration
  • No USB-C output is available, which restricts direct connectivity to displays or devices that rely on that port
  • The card's length of 328.9 mm may create fitment challenges in smaller or mid-tower cases
Who is this for?

This card is well matched to users who prioritize high-fidelity gaming with ray tracing and DLSS enabled, as both features are supported natively and the 37.85 TFLOPS of floating-point throughput provides meaningful compute headroom for demanding rendered scenes. The 12GB of GDDR6X memory at 504 GB/s bandwidth also makes it a reasonable fit for creative and compute workloads such as 3D rendering or machine learning inference, particularly given the inclusion of ECC memory support and Double Precision Floating Point capability. Users running multi-monitor configurations of up to four displays will find the port layout — three DisplayPort outputs plus one HDMI 2.1a — well suited to their needs without requiring additional adapters.

Who is this NOT for?

Users working within small form factor or compact mid-tower builds may find the card's 328.9 mm length a practical obstacle, as fitment can become a genuine concern in cases with limited internal clearance. Those who require liquid cooling integration will need to look elsewhere, since water cooling is not supported and thermal management relies solely on the air cooler. Additionally, users with displays or devices that depend on USB-C connectivity will find no native support here, as the card provides zero USB-C outputs, which could be a limiting factor for certain modern monitor setups.
