EVGA RTX 3080 Ti XC3 ULTRA HYDRO COPPER GAMING

Superior Performance and Ampere Architecture

The EVGA GeForce RTX 3080 Ti XC3 ULTRA HYDRO COPPER GAMING (12G-P5-3959-KR) leverages NVIDIA’s Ampere architecture with 10,240 CUDA cores and a 1,725 MHz boost clock. Featuring 12GB GDDR6X memory at 19 Gbps (912 GB/s bandwidth), it delivers near RTX 3090 performance for 4K/120Hz gaming and creative workloads. Enhanced 2nd Gen Ray Tracing and 3rd Gen Tensor Cores support DLSS, excelling in titles like *Call of Duty: Warzone* at 4K/60Hz with ray tracing. Users praise its 1440p/144Hz fluidity but note it requires DLSS for 4K ray tracing.

Hydro Copper Cooling and ARGB Aesthetics

The full-cover Hydro Copper waterblock cools the GPU, VRAM, and VRM, maintaining temperatures at ~50–55°C in a custom loop with a 360mm+ radiator. Three independent ARGB zones, customizable via EVGA Precision X1, sync with other components. The metal backplate enhances durability. Its compact 1.2-slot design (262.8 x 132.1 mm) suits smaller cases, but a custom loop is mandatory. Users highlight low temps but note added cost and complexity of liquid cooling.

Robust Connectivity and LHR Technology

Supporting PCIe 4.0, the card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a for 4K/120Hz or 8K/60Hz HDR displays. It requires a 750W PSU with two 8-pin PCIe connectors (350W TDP). The LHR (Lite Hash Rate) variant limits Ethereum mining to ~40 MH/s, prioritizing gamers. The NVENC encoder ensures smooth streaming. Users value the connectivity but caution about high power demands and the need for a custom water-cooling loop.
