The NVIDIA GeForce RTX 4080 SUPER is a refresh successor in the ADA series, and is set to replace the current Ampere-based 4080. This graphics card is equipped with 16 Gigabytes of GDDR6X memory, operating at an effective data rate of 23 Gbps. This configuration results in a memory bandwidth of 736 GB/sec. 


While last-gen GeForce RTX 3080 Ti featured 10240 stream/shader processors, the RTX 4080 SUPER also offers 10240 shading cores and delivers markedly higher performance. NVIDIA exclusively provides power adapters for the RTX 40-series graphics cards, applicable to both Founders Edition and custom designs by partners. The 12VHPWR connector has been an topic of discussion due to isolated overheating incidents, potentially linked to cable bending, user installation, or quality control issues. However, these connectors generally maintain a safe temperature under normal usage conditions.


The GeForce RTX 4000 series, while adhering to PCIe Gen 5 specifications, operates using a PCIe Gen 4.0 x16 host interface. Similarly, the RTX 4080 / SUPER 16GB GDDR6X memory, with its 256-bit wide memory bus, offers significant bandwidth and storage capacity. Despite its 320W Total Graphics Power (TGP), a 650-watt power supply is recommended, although the actual power consumption typically ranges between 275-300 Watts. Keep in mind that board partners may allow for higher TGP, potentially leading to increased power usage in certain configurations, alongside a notch of extra performance of course.


The RTX 4080 SUPER card exhibits a nicely crafted design that mirrors that of the RTX 4080 Founders Edition, maintaining the previous-generation Dual-Axial Flow-Through cooling architecture.


This cooling system has been enhanced with larger radiators and fans for improved thermal management. The SUPER edition cards are themed a bit darker in aesthetics though, which I do like tbh.
