The Ryzen Z2 Go GPU has no recorded benchmarks and sits at the 50th percentile with a score of zero. For any analysis requiring measured results, the Radeon 680M is the only option with evidence.

The Ryzen Z2 Go GPU wins on paper in raw compute and memory characteristics. Its FP32 output of 4.147 TFLOPS exceeds the Radeon 680M's 3.379 TFLOPS, and its FP16 output of 8.294 TFLOPS exceeds the 6.758 TFLOPS of the 680M. The dedicated 16 GB LPDDR5 memory with 102.4 GB/s of bandwidth contrasts with the system shared memory of the Radeon 680M, whose bandwidth is system dependent. The Z2 Go GPU also reaches a higher boost clock of 2700 MHz versus 2200 MHz, and its pixel rate and texture rate are both higher.

The Radeon 680M wins in base clock stability, with 2000 MHz versus 800 MHz for the Z2 Go GPU. It also carries a higher TDP of 50 W compared to 28 W, which may indicate a higher sustained power allocation. The Radeon 680M includes a PCIe 4.0 x8 bus interface, which the Z2 Go GPU lacks in the records.

The use-case split follows the data. The Radeon 680M suits scenarios where measured performance and broad compatibility matter, supported by its benchmark results and 57th percentile rank. The Ryzen Z2 Go GPU suits scenarios where peak compute, higher boost capability, and dedicated memory bandwidth are priorities, based on its specification sheet. The Z2 Go GPU's console GPU classification and single USB Type-C display output suggest a more constrained deployment, while the 680M's portable device dependent display outputs align with mobile integration. Neither GPU has a launch MSRP recorded, so no pricing analysis is possible from this data.
