AMD Ryzen 5 7500X3D vs Intel Core i5-14500HX Comparison

The AMD Ryzen 5 7500X3D and the Intel Core i5-14500HX occupy different corners of the processor market, yet their benchmark results reveal a surprisingly competitive overlap. The data shows the Intel chip secures a decisive 8 to 3 win count in direct head-to-head tests, but the AMD processor counters with massive advantages in specific workloads that point to entirely different use-case strengths.

Head-to-Head Benchmarks

The most striking result in the database is the AMD Ryzen 5 7500X3D's performance in the prime number search test. It scores 221 against Intel's 130, a 70% advantage that is by far the largest delta between the two processors. This is a specialized compute pattern, but the margin is so wide it signals a fundamental efficiency difference in that instruction flow.

The AMD chip also dominates the physics test, scoring 2779 versus 1911, a 45.4% lead. This workload typically scales with cache access and memory latency, where the AMD part's architecture shows clear strength. In extended instructions, the AMD processor wins by a narrower 2.2% margin, scoring 20455 against 20019, which keeps it competitive in that segment.

Every other recorded benchmark favors the Intel Core i5-14500HX. The largest Intel win is in floating point math, where it scores 69442 against 43594, a 37.2% advantage. Integer math follows with a 26% lead, as Intel scores 95584 versus 70774. Data compression shows Intel ahead by 18.6%, scoring 333851 against 271649. Data encryption is close behind at a 19% delta, with Intel at 19502 and AMD at 15797.

The multithread score, a broad indicator of overall throughput, goes to Intel by 12.1%, with 28508 versus 25047. Random string sorting favors Intel by 8.9% (36219 vs 32999), and single thread performance goes to Intel by 3.7%, with 3629 against 3494.

The average benchmark score confirms the overall picture: the Intel part records 35094, while the AMD part records 44573. This apparent contradiction, where the AMD average is higher despite losing most head-to-head tests, reflects the different test suites recorded for each processor. The AMD Ryzen 5 7500X3D sits at the 89th percentile of all CPUs, while the Intel Core i5-14500HX sits at the 84th percentile.

The Verdict

The data points to a clear split based on workload type. The Intel Core i5-14500HX is the stronger general-purpose processor, delivering higher scores in eight of eleven direct comparisons, including the important multithread and single thread metrics. It leads in floating point math by 37.2% and integer math by 26%, which makes it the better choice for numerically intensive tasks.

The AMD Ryzen 5 7500X3D is the specialist. Its 70% lead in prime number finding and 45.4% lead in physics indicate a processor that excels in latency-sensitive or cache-dependent workloads. Its 2.2% win in extended instructions adds a third category where it holds an edge.

For users running physics simulations, prime number computations, or extended instruction sets, the AMD part is the clear winner from the recorded data. For everything else, particularly floating point, integer, and data compression workloads, the Intel part delivers higher scores. The Intel chip's 14 cores and 20 threads provide a structural advantage in parallel throughput, which shows up in the 12.1% multithread lead.
