Exceptional Performance and Ampere Architecture
The EVGA GeForce RTX 3080 Ti XC3 ULTRA GAMING (12G-P5-3955-KR) is powered by NVIDIA’s Ampere architecture, featuring 10,240 CUDA cores and a 1,725 MHz boost clock. With 12GB GDDR6X memory at 19 Gbps (912 GB/s bandwidth), it delivers near RTX 3090 performance for 4K gaming and creative workloads. Enhanced 2nd Gen Ray Tracing and 3rd Gen Tensor Cores support DLSS and ray tracing, excelling in titles like *Cyberpunk 2077* at 4K/60Hz with DLSS. Users praise its performance but note diminishing returns for the price compared to the RTX 3090.
Advanced iCX3 Cooling and ARGB Aesthetics
The card features EVGA’s iCX3 cooling with triple HDB fans and a 25% larger copper base, ensuring efficient heat dissipation (~65–70°C under load). Fans stop below 55°C for 0dB operation, minimizing noise (~30 dB). Adjustable ARGB LEDs, customizable via EVGA Precision X1, sync with other components. The compact 2-slot design (285.37 x 111.15 mm) suits smaller cases, but cooling is less effective than the FTW3 variant. Users note occasional coil whine and high temperatures (~86°C) without proper airflow.
Robust Connectivity and LHR Technology
The RTX 3080 Ti XC3 ULTRA supports PCIe 4.0 with 1x HDMI 2.1 and 3x DisplayPort 1.4a, enabling 4K/120Hz or 8K/60Hz HDR displays. It requires an 850W 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 appreciate the connectivity but caution about power demands and potential fan noise under load.
