NVIDIA Driver Leak Reveals RTX 5070 GB203 Silicon Variant

Hardware documentation discovered within NVIDIA's September 9 graphics driver release confirmed that select RTX 5070 graphics cards will ship with harvested 378mm² GB203 silicon rather than the standard GB205 die. The die swap delivers higher memory bus bandwidth and expanded FP8 Tensor Core capacity, giving buyers of the GB203 variant modest performance gains on local generative model serving.
