EVGA RTX 3080 XC3 ULTRA

Performance and Ampere Architecture

The EVGA GeForce RTX 3080 12GB XC3 ULTRA GAMING (12G-P5-4865-KL) is powered by NVIDIA’s Ampere architecture (GA102-220-A1), featuring 8,960 CUDA cores, 280 TMUs, 96 ROPs, and a 1,755 MHz boost clock. With 12GB GDDR6X memory at 19 Gbps (912 GB/s bandwidth), it delivers ~90–110 FPS in *Starfield* at 4K Ultra with DLSS and ~120–140 FPS at 1440p Ultra. Supports 2nd Gen RT Cores, 3rd Gen Tensor Cores, DLSS, NVIDIA Reflex, DirectX 12 Ultimate, and Vulkan RT API. Users praise 4K/1440p gaming and creative tasks (e.g., DaVinci Resolve) but note high power draw. ~15–20% faster than RTX 3080 10GB, ~5–10% slower than RTX 3080 Ti. LHR caps ETH mining at ~52 MH/s.

iCX3 Cooling and ARGB Lighting

Equipped with three 90mm fans using iCX3 cooling technology, an optimized heatsink, and a metal backplate, it maintains ~65–70°C under load with moderate noise (~35–40 dB). Features fan-stop technology (fans stop below 55°C) and customizable ARGB lighting via EVGA Precision X1. The 2.2-slot design (285 x 111 x 45 mm) includes nine thermal sensors for precise cooling. Users commend low temps but note louder fans under load (~70% speed). Overclocking to ~1,950 MHz boosts FPS by ~5–7%. Clean fans every 6–12 months. Some report coil whine, mitigated by undervolting to 950mV.

Connectivity and Power Requirements

Supports PCIe 4.0 x16, with 1x HDMI 2.1 and 3x DisplayPort 1.4a for 4K/120Hz or 8K/60Hz, handling up to four monitors. With a 350W TDP, it requires a 750W PSU and 2x 8-pin PCIe connectors. Users value VR-ready performance and NVENC for streaming but note high heat output and need for robust case airflow. Ideal for high-end gaming PCs and workstations.
