RTX Spark To Have Two Variants With Different CUDA Core Counts, Top-End Version Features 6,144, According To Details Spotted In Windows 11 Drivers
NVIDIA's upcoming RTX Spark will feature two configurations, with the higher model boasting 6,144 CUDA cores. These details come from a driver leak, hinting at the graphics chip's architecture and potential performance. Alongside a MediaTek CPU, the GPU configurations suggest a focus on balancing compute power and memory support for consumers. Despite the promise of high core counts, performance comparisons with existing models, such as the desktop RTX 5070, imply cautious expectations about actual efficiency gains.
