The 912-V389-263, known as the MSI GeForce RTX 3080 Ventus 3X Plus 10G OC LHR, is a top-of-the-line graphics card designed with high-end gaming and content creation in mind. Featuring NVIDIA's Ampere architecture, this card includes ray tracing cores, tensor cores, and streaming multiprocessors to deliver a massive leap in performance and realism. MSI's Ventus 3X Plus model brings a triple-fan cooling system and enhanced clock speeds for better heat dissipation and sustained high performance. With 10GB of GDDR6X memory, it's adept at handling 4K gaming and complex rendering tasks. The 'OC' indicates a factory overclock for additional performance right out of the box. The inclusion of 'LHR' (Lite Hash Rate) indicates a limitation on the mining capability of the card, making it more available for gamers and less attractive for cryptocurrency mining operations.
