Zotac GeForce RTX 4080 Super PGF OC

Manufacturer: Zotac

The Zotac GeForce RTX 4080 Super PGF OC is a graphics card built on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process and housing 45,900 million transistors. It runs at a base clock of 2295 MHz with a boost of 2550 MHz, and its physical dimensions of 309 mm in width and 139 mm in height place it in the range of larger triple-fan designs. RGB lighting is integrated into the card, and cooling is handled entirely through air, with no water cooling option available.

The card is equipped with 16GB of GDDR6X memory on a 256-bit bus, reaching an effective speed of 23,000 MHz and a peak bandwidth of 736.3 GB/s. Its 10,240 shading units, 320 texture mapping units, and 112 render output units yield a texture rate of 816 GTexels/s and floating-point performance of 52.22 TFLOPS. Ray tracing and DLSS are both supported alongside DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, with ECC memory and Intel Resizable BAR also included. Display output consists of one HDMI 2.1a port and three DisplayPort connections, supporting up to four screens simultaneously, with a TDP of 320W and a PCIe 4 interface.

Pros
  • Ray tracing and DLSS are both supported, enabling access to two significant rendering technologies within a single card
  • Three DisplayPort outputs alongside one HDMI 2.1a port allow for flexible multi-monitor configurations across up to four displays
  • ECC memory support makes the card viable for workloads where memory integrity and error correction are functionally important
  • Intel Resizable BAR is included, allowing the processor to access the full GPU frame buffer for more efficient data transfers
  • No LHR restrictions are present, meaning compute throughput is fully available without any artificial limitations
  • RGB lighting is integrated into the card for users who want visual customization within their build
Cons
  • A 320W TDP places significant demands on the system power supply, requiring careful planning around the overall power budget
  • Water cooling is not supported, so thermal management is entirely dependent on the air cooling solution the card ships with
  • No USB-C, DVI, or mini DisplayPort outputs are available, which may limit compatibility with certain monitors or capture devices
  • At 309 mm in width and 139 mm in height, the card's footprint may not fit in compact or mid-tower cases with limited clearance
Who is this for?

The Zotac GeForce RTX 4080 Super PGF OC is well-suited to users engaged in graphically intensive rendering, 3D content creation, or compute tasks that benefit from 52.22 TFLOPS of floating-point performance and ECC memory support for data integrity. The three DisplayPort outputs combined with one HDMI 2.1a port make it a practical fit for users running multi-monitor setups of up to four displays, whether for creative workflows or expansive desktop configurations. Those working within full-tower or large mid-tower cases will have little trouble accommodating its 309 mm width, and the inclusion of Intel Resizable BAR and DLSS with ray tracing support makes it relevant for users who regularly work across both real-time rendering and compute-heavy pipelines.

Who is this NOT for?

Users building systems with limited power headroom will find the 320W TDP a challenging requirement, as it places considerable load on the power supply and surrounding components. Those who prefer or require water cooling integration will need to look elsewhere, since this card supports air cooling only and offers no provision for liquid cooling loops. Additionally, users who depend on USB-C, DVI, or mini DisplayPort connectivity for their monitors or peripheral equipment will face compatibility gaps, as none of these output types are present on this model.
