Architecture Differences

Both GPUs are built on the Blackwell 2.0 architecture, but they use different physical chips. The RTX 5070 Mobile uses the GB206 chip, which has a die size of 181 mm² and contains 21,900 million transistors. The RTX 5080 Mobile uses the larger GB203 chip, which has a die size of 378 mm² and contains 45,600 million transistors. Despite the larger die, the transistor density is nearly identical: 121.0M / mm² for the RTX 5070 Mobile and 120.6M / mm² for the RTX 5080 Mobile.

The difference in chip size directly translates to a difference in execution resources. The RTX 5080 Mobile has 7680 shading units, 240 texture mapping units, and 96 render output units. The RTX 5070 Mobile has 4608 shading units, 144 texture mapping units, and 48 render output units. This means the RTX 5080 Mobile has 66.7% more shading units and twice the ROPs of the RTX 5070 Mobile.

The ray tracing and AI acceleration hardware also scales accordingly. The RTX 5080 Mobile has 60 RT cores and 240 tensor cores, while the RTX 5070 Mobile has 36 RT cores and 144 tensor cores. Both GPUs share the same API support, including DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
