AMD's Data Center revenue more than doubled, but its next gross-margin guide stayed flat

AMD's Q2 numbers look like clear proof of AI demand: \- Total revenue: $11.536B, up 50% year over year \- Data Center revenue: $6.7B, up 107% \- Data Center is now roughly 58% of total revenue \- Q2 non-GAAP gross margin: 56% \- Q3 revenue guide: about $13.0B, plus or minus $300M \- Q3 non-GAAP gross-margin guide: still about 56% That is the tension for me. If the fastest-growing business is also becoming most of the company, why is the consolidated margin guide not moving? There are several reasonable explanations: accelerator ramp costs, advanced-packaging and memory constraints, product mix, pricing to win large deployments, or spending ahead of MI450 and Helios scale. One quarter cannot tell us which mechanism dominates. The bull case is that AMD is absorbing transition costs now and that Instinct plus EPYC volume eventually creates operating leverage. The bear case is that AMD can win substantial AI revenue without capturing enough incremental gross profit because competition and system costs remain intense. The next result I care about is not another revenue record. It is whether each additional dollar of Data Center revenue begins to produce more gross profit and free cash flow. What do you think the flat 56% guide represents: temporary ramp economics, aggressive pricing for market share, or a more durable ceiling on the current mix?
