Xiaomi CPU Matches Apple Silicon, Chinese Hardware Competition Heats Up
Xiaomi announced a new CPU that matches Apple's cores in single-threaded performance and beats them significantly in multithreaded workloads. Daniel Lemire posted benchmark data on X and the HN thread picked it up fast. The chip uses LPDDR6, which several commenters flagged as still insufficient for fast local inference, but the single-threaded parity with Apple is the headline number.
The pattern here is geopolitical as much as technical. One commenter noted the obvious: lobbyists are probably already drafting national security memos. This is the same frame that got Huawei blocked and TSMC export controls tightened. A Chinese chip that matches Apple silicon in performance is not just a product announcement, it is a political event.
For builders, the SiFive RISC-V server platform also appeared in the threads today, priced at over $100K for a 256GB DDR5 configuration. Two different bets on non-x86, non-ARM compute are visible simultaneously, one from China and one from the open-source ISA world.
So what?
The assumption that Apple silicon is the unchallenged leader in performance-per-watt is now genuinely contested. If you are making hardware purchasing decisions for inference workloads, the competitive landscape is moving faster than procurement cycles. Watch the LPDDR6 inference benchmarks specifically, that is the bottleneck the commenters identified.
