Ampere Architecture and Performance
The EVGA GeForce RTX 3080 Ti XC3 ULTRA HYBRID GAMING (12G-P5-3958-KR) leverages NVIDIA’s Ampere architecture, featuring 10240 CUDA cores and a 1725 MHz boost clock. Its 12GB GDDR6X memory at 19 Gbps (912 GB/s bandwidth) delivers exceptional 4K (~90–110 FPS in *Cyberpunk 2077* Ultra with DLSS) and solid 1440p (~120–140 FPS) gaming. It includes 2nd Gen Ray Tracing Cores, 3rd Gen Tensor Cores, DLSS, LHR (~43 MH/s), and NVENC for streaming. Users praise its 4K performance and ~10% boost over RTX 3080, but note high power draw (~350–400W). Ideal for high-end gaming and creative workloads.
Hybrid Cooling and Premium Design
The iCX3 hybrid cooling system combines a 240mm AIO liquid cooler with a single fan, maintaining GPU temperatures at ~50–55°C under load with low noise (~25–30 dB). VRAM and VRM stay cooler (~60–65°C) than air-cooled models. The 2-slot design (263 x 111 x 40 mm) includes ARGB LED and a metal backplate. Users commend its low temps and quiet operation but note occasional pump noise or coil whine and the need for radiator space. Use EVGA Precision X1 for fan, ARGB, and overclocking control.
Connectivity and Power Requirements
Supporting PCIe 4.0 x16, the card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a for 4K/120Hz or 8K/60Hz displays. It requires a 750W PSU with two 8-pin PCIe connectors (350W TDP). Users value its 8K HDR support and multi-monitor capability (up to 4) but caution about PSU quality, case space for the 240mm radiator, and potential sag. LHR limits mining performance (~43 MH/s). Ideal for enthusiasts.
