Inno3D GeForce RTX 4080 Super iChill Black

Manufacturer: Inno3D

The Inno3D GeForce RTX 4080 Super iChill Black is a graphics card built on the Ada Lovelace architecture, manufactured at 5 nm and integrating 45,900 million transistors. It operates at a base clock of 2295 MHz with a boost frequency reaching 2610 MHz, and its 10,240 shading units contribute to a floating-point output of 53.45 TFLOPS. The card measures 280 mm in width and 137 mm in height, includes RGB lighting, and supports up to four simultaneous display outputs.

Memory consists of 16GB of GDDR6X on a 256-bit bus running at an effective 23,000 MHz, delivering a maximum bandwidth of 736 GB/s, with ECC memory support also included. The feature set covers ray tracing, DLSS, DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, stereoscopic 3D, and Intel Resizable BAR, while LHR is not present and XeSS is not supported. Output connectivity includes one HDMI 2.1a port and three DisplayPort outputs, with no USB-C, DVI, or mini DisplayPort available. The card carries a rated TDP of 320W and relies on air cooling only.

Pros
  • 16GB of GDDR6X VRAM on a 256-bit bus with an effective speed of 23,000 MHz gives the card substantial memory throughput for texture-heavy and memory-intensive workloads
  • 53.45 TFLOPS of floating-point performance, backed by 10,240 shading units, provides meaningful compute capacity for both rendering and general GPU workloads
  • ECC memory support adds a layer of data integrity that benefits users running compute-sensitive tasks alongside graphical workloads
  • Ray tracing and DLSS are both supported, enabling hardware-accelerated visual effects and AI-based upscaling without requiring additional configuration
  • LHR is not active on this model, removing any built-in limitations on compute-oriented use cases
  • At 280 mm in length and 137 mm in height, the card occupies a more moderate footprint than many cards in this performance tier, making case compatibility less of a concern
Cons
  • A 320W TDP places significant power demands on the host system, requiring a well-rated power supply and adequate case airflow to maintain stable operation
  • Air-water cooling is not included, so thermal management depends entirely on the card's air cooling solution under sustained loads
  • XeSS (XMX) is not supported, leaving DLSS as the only available upscaling technology with no alternative for users who prefer a different option
  • There are no USB-C, DVI, or mini DisplayPort outputs, which limits display compatibility for users relying on those connection types
Who is this for?

The Inno3D GeForce RTX 4080 Super iChill Black is well-matched to users who need substantial compute and rendering throughput, with 53.45 TFLOPS of floating-point performance and 16GB of GDDR6X VRAM providing ample headroom for demanding graphical and GPU compute workloads. Its support for ray tracing, DLSS, and DirectX 12 Ultimate makes it a practical fit for users working in real-time rendering environments where visual quality and frame stability are priorities. The absence of LHR and the inclusion of ECC memory also make it a reasonable choice for users who split their GPU usage between graphics and compute-intensive tasks that require memory accuracy.

Who is this NOT for?

Users building into compact or small-form-factor systems may find the 280 mm length and 137 mm height less accommodating, and should verify clearance before committing to this card. The 320W TDP demands a robust power supply and well-ventilated case, making it a poor fit for systems with limited power headroom or restricted airflow. Additionally, users who depend on USB-C, DVI, or mini DisplayPort outputs for their display configuration will find no support for those connection types on this card.

width 280 mm
height 137 mm

The Inno3D GeForce RTX 4080 Super iChill Black is grounded in the Ada Lovelace architecture, built on a 5 nm process with 45,900 million transistors and interfacing with the system through PCIe 4. Its thermal design power is rated at 320W, and cooling is handled exclusively through air, as air-water cooling is not included. The card measures 280 mm in width and 137 mm in height, which is worth accounting for when assessing case compatibility.

Final Verdict

The Inno3D GeForce RTX 4080 Super iChill Black is a specification-dense graphics card that brings together 53.45 TFLOPS of floating-point performance and 16GB of GDDR6X VRAM in a form factor that is more manageable than many cards in this performance bracket. Ray tracing, DLSS, ECC memory support, and the absence of LHR give it genuine breadth across both graphical and compute use cases, while Intel Resizable BAR and DirectX 12 Ultimate round out a capable feature set. Users should account for the 320W power requirement and the reliance on air cooling alone when planning their system build. For those whose setup can accommodate these demands, this card delivers a thorough and well-rounded specification profile that holds up across a wide range of workloads.
