The data indicates that the AMD part's average score is boosted significantly by its very high extended instructions result and strong single-thread performance. Intel's average is dragged down by its lower single-thread scores, despite winning the majority of the head-to-head tests. This is a classic case where the aggregate average tells a different story than the individual matchups.

The two processors are close in several areas. In data compression, the difference is only 0.6%. In random string sorting, it is 0.4%. In multithread, it is 0%. These near-ties suggest that for many common productivity tasks, the choice between the two may not be driven by raw CPU performance alone.

The Verdict

The data shows two distinct profiles. The Intel Core i7-14650HX is the stronger choice for multicore rendering workloads. Its 17.2% lead in Cinebench R15 multicore and 8.3% lead in Cinebench R23 multicore are the most decisive victories in the dataset. It also leads in physics, floating point math, data encryption, and integer math. Any workload that scales across many threads and relies on heavy arithmetic will favor Intel.

The AMD Ryzen AI Max+ 388 is the better option for single-thread performance and extended instruction set usage. Its 9% lead in PassMark single-thread and 35.5% lead in extended instructions are significant. The 4.4% edge in Cinebench R15 single-core reinforces this. For applications that are lightly threaded or that make heavy use of SIMD and other advanced instructions, AMD has the advantage.

The 0% delta in PassMark multithread is important context. It means that for a broad, aggregate measure of multithreaded performance, the two processors are indistinguishable. The differences appear in specific workload types, not in overall throughput.

Given the data, the Intel Core i7-14650HX is the pick for users whose primary workloads are rendering, physics simulation, or heavy floating-point computation. The AMD Ryzen AI Max+ 388 is the pick for users who prioritize single-thread responsiveness and workloads that benefit from extended instruction sets. The average benchmark score in the database favors AMD, but the head-to-head results favor Intel in more individual tests.

The percentile rankings are close, with AMD at 90 and Intel at 88. The nearest rival data shows both processors sitting in a competitive cluster. AMD's nearest rival, the Intel Core 9 273PE, is only 0.1% ahead. Intel's nearest rival, the Intel Core Ultra 7 265H, is also only 0.1% ahead. Both chips are well within the same performance tier.
