Built for 4K creators and competitive gamers

This ROG STRIX GeForce RTX 3080 Ti ships with 12GB of GDDR6X memory across a 384-bit bus and 10240 CUDA cores. The PCI Express 4.0 x16 interface feeds data to the GPU at full speed. Two HDMI 2.1 and three DisplayPort 1.4a outputs drive up to four displays at 7680 x 4320 resolution.

Hybrid cooling keeps clocks steady through long

The liquid loop moves heat away from the GPU die while a shroud fan handles VRM and memory thermals. In OC mode the boost clock holds at 1860 MHz; gaming mode runs at 1830 MHz. Memory stays at 19 Gbps effective, so frame pacing remains consistent during extended rendering or raid encounters.

Power draw and acoustics balanced for daily use

Three 8-pin connectors draw from an 850W supply to sustain the 3080 Ti under full load. The hybrid design shifts most thermal mass to the radiator, lowering in-case temperatures and reducing fan speed compared with air-only models. HDCP 2.3 support secures protected content playback without extra hardware.

Perguntas sobre este artigo

How loud and hot does the ROG STRIX LC RTX 3080 Ti run with its hybrid cooler under all-day load?

The hybrid cooler combines a liquid-chilled cold plate for the GPU with a blower-style fan that exhausts heat directly out the rear bracket, keeping core temperatures lower than air-only designs while the single fan runs at moderate RPM for typical gaming loads.

What power supply and connectors must my system already have for the 850 W recommended PSU and three 8-pin plugs on this card?

You need a power supply rated for at least 850 W with three dedicated 8-pin PCIe power cables; adapters or daisy-chained cables are not recommended for stable operation.

Will the PCI Express 4.0 x16 interface and HDMI 2.1 ports work properly on my older PCIe 3.0 motherboard and HDMI 2.0 monitor?

Yes, the card is backward compatible — it will run at PCIe 3.0 x16 speeds on a 3.0 slot with negligible performance loss, and the HDMI 2.1 ports will drive an HDMI 2.0 display at its native 4K 60 Hz limit.
