Ethup Arc Ultra RTX 4090 Ti 24GB Graphics Card

The Ethup Arc Ultra RTX 4090 Ti 24GB represents the engineering ceiling of what is currently achievable in consumer GPU design, combining 24GB of GDDR6X memory operating at 21 Gbps across a 384-bit interface with a shader processor count of 16,384 unified cores arranged in a monolithic die configuration that Ethup’s manufacturing partners have validated for sustained boost clock operation at 2.85 GHz under the thermal management system provided. The quad-fan cooling solution — a feature unique to Ethup’s flagship tier — uses four independent 85mm fans in a staggered push-pull configuration across a triple-radiator fin stack that maintains junction temperature below 85 degrees Celsius during extended full-load operation in a standard mid-tower chassis with reasonable ambient airflow. The base fan profile keeps all four fans below 1,000 RPM during desktop workloads and light gaming, making the card effectively inaudible from normal seated distances despite its thermal capacity. A full-coverage nickel-plated copper backplate provides structural rigidity to prevent GPU sag on the PCIe slot and conducts heat from the rear of the PCB through thermal pads to the backplate surface for radiation into the case airstream. Power delivery architecture uses a 24-phase VRM with 90A power stages capable of sustaining the 600W peak TGP this card reaches under extreme overclocking conditions, fed through three 16-pin PCIe Gen5 connectors. The display output array includes four DisplayPort 2.1 UHBR20 ports and two HDMI 2.1 48Gbps ports, supporting simultaneous 6-display output configurations for professional multi-monitor trading, creative, or simulation workstation builds. Hardware ray tracing acceleration is provided through 128 second-generation RT cores delivering real-time path tracing performance in supported titles. The ArcControl Extreme software suite exclusive to the Ultra tier adds AI-powered auto-overclocking that profiles the individual silicon sample installed and applies a validated maximum stable overclock automatically, a process that previously required hours of manual testing with specialized tools.
