AMD Radeon 780M (Ryzen 7 7840U / 7840HS, dual-channel DDR5-5600)

Keyed by chip plus memory configuration rather than by product, matching ryzen-ai-max-395-128gb and core-ultra-7-258v. It covers the Ryzen 7 7840U and 7840HS, which AMD gives identical memory support (DDR5-5600 or LPDDR5x-7500) and the same Radeon 780M with 12 compute units; they differ only in TDP, 28W against 35-54W. Decode is bandwidth-bound, so that difference does not reach the tokens-per-second figure, though it does affect prompt processing. 89.6 GB/s is arithmetic from the stated memory -- 5600 MT/s across a 128-bit dual-channel bus -- not inferred from any measurement. THE MEMORY MUST BE STATED BY THE AUTHOR for a run to belong here: the same silicon on LPDDR5x-7500 is 120 GB/s, a third faster, and several otherwise-usable runs on sibling AMD APUs have been refused for exactly this reason. Form factor is recorded as mini-pc because that is the commonest enclosure for this chip, but the entry also covers laptops such as the Framework 13; a run's chassis is noted on the record rather than here. No price: this chip ships in many machines at very different prices and no single representative listing was verified.
