Where Each One Wins

The AMD Ryzen Z2 A GPU wins in power efficiency. Its 15 W TDP is one quarter of the NVIDIA part's 60 W TDP, making it suitable for compact handheld devices with limited cooling and battery capacity. It also offers more memory capacity at 16 GB versus 12 GB, which matters for workloads that need larger working sets rather than raw throughput. Its base and boost clocks are higher at 1000 MHz and 1600 MHz respectively, though this does not translate into competitive compute rates given the massive core count difference. The AMD part uses a single USB Type-C display output, which fits the minimal I/O of a portable device. Its release date of December 2024 predates the NVIDIA part by roughly two months, so it had earlier availability in the database timeline.

The NVIDIA GeForce RTX 5070 Ti Mobile wins in every measured performance category. Its FP32 output of 17.04 TFLOPS is 10.4x the AMD part. Its texture rate of 266.2 GTexel/s is 5.2x higher, and its pixel rate of 115.8 GPixel/s is 4.5x higher. The 184 TMUs and 80 ROPs dwarf the AMD part's 32 TMUs and 16 ROPs. The 5,888 shading units provide 11.5x the shader throughput. The 46 RT cores give it a substantial advantage in ray-traced workloads, and the 184 tensor cores enable AI acceleration that the AMD part cannot match. The GDDR7 memory with 672.0 GB/s bandwidth is 6.6x faster than the LPDDR5 setup, and the 192-bit bus moves 50% more data per cycle than the 128-bit bus. The PCIe 5.0 x16 interface provides a modern host connection, while the AMD part lists no bus interface. The NVIDIA part's 80th percentile ranking versus the AMD part's 50th percentile ranking in the database confirms the performance gap. Its average benchmark score of 35,435 places it within 2.4% of workstation-class rivals like the Quadro GV100 and Radeon Pro Duo, indicating that it delivers near-workstation compute performance in a 60 W mobile package. The AMD part has no benchmark presence, so the database cannot substantiate any performance claim for it. For gaming, rendering, ray tracing, or compute tasks, the RTX 5070 Ti Mobile is the only defensible choice based on recorded data. For ultra-portable, low-power devices where battery life and thermal limits dominate, the AMD Ryzen Z2 A GPU is the appropriate fit.
