Differences first. Select a topic for its graphic, sources and conditions.
Check the exact configuration and source conditions for your use.
Plan the complete platform. Check the exact CPU-support list, required BIOS and memory validation before buying. PCIe generations and lane allocations can change with the processor. A socket match or slot count is not a guarantee that every component works together at its highest advertised setting.
10 verified differences, most decision-relevant first. 7 are also drawn in Visual facts above. Missing information stays separate.
