The Nvidia GK208B graphics processing unit (GPU) is a member of Nvidia's Kepler family, designed for the entry-level segment of the market. It powers the GeForce GT730, offering a cost-effective solution for casual gaming, multimedia applications, and general computing tasks. Despite its entry-level positioning, the GK208B features some of the architectural advancements of the Kepler series, including support for DirectX 11 for the latest games and CUDA, which allows it to perform GPU-accelerated tasks, enhancing performance in compatible applications. It also supports Nvidia's PhysX technology, providing more realistic physics in supported games. With its low power consumption and modest thermal design power (TDP), the GK208B is ideal for small form factor systems or HTPCs. It provides a good balance of performance and power efficiency at an affordable price point, making it suitable for upgrading older systems or building budget-conscious PCs for light gaming and multimedia enjoyment.
