The Verdict

The benchmark data splits this comparison into two distinct profiles. The AMD Ryzen AI 5 340 holds the overall average score advantage at 25981 versus 18188, a difference that places it in the 78th percentile against all CPUs compared to the 72nd percentile for the Intel Core 5 315. AMD also wins 9 of the 15 head-to-head comparisons, including the largest margin of the entire dataset.

The Intel Core 5 315, however, is not simply slower across the board. It wins the Cinebench R23 multi-core test, which is the most widely referenced rendering benchmark in the database, and it takes every PassMark single-threaded metric recorded. Its 3 nm process and 15 W TDP indicate a different design priority, and the data shows it holding its own in floating point and physics workloads.

The AMD processor is the stronger all-around performer in this comparison. Its 12 threads, dual-channel memory bus, wider PCIe allocation, and higher boost clock translate into large wins in multi-threaded and integer-heavy workloads. The Intel processor is competitive in specific single-threaded and floating-point tasks but trails in the aggregate.

Buyers choosing between the two should rely on workload patterns. The AMD chip delivers the higher average score, more head-to-head wins, and a commanding lead in compression, encryption, and integer math. The Intel chip wins the most common render test and the single-thread PassMark tests, but its overall score deficit is substantial.

Where Each One Wins

The AMD Ryzen AI 5 340 wins in multi-threaded productivity. Cinebench R15 multi-core shows a 46.4% lead, and PassMark multithread shows a 27.7% lead. Data compression favors AMD by 57.2%, integer math by 99%, and random string sorting by 42.3%. These results point to workloads that use many threads and process large amounts of data, such as compression utilities, encryption tasks, and integer-heavy computation.

The AMD chip also wins in extended instruction workloads, with a 25.1% margin in PassMark extended instructions, and in data encryption, with a 3.2% margin. Cinebench R15 single-core and R23 single-core also go to AMD, with margins of 31.8% and 4.6%, respectively.

The Intel Core 5 315 wins in floating point and physics simulation. PassMark floating point math goes to Intel by 5.8%, and PassMark physics goes to Intel by 5.8% as well. Prime number finding, which is a scalar integer workload with low thread scaling, goes to Intel by 35.7%. The PassMark single-thread and single-threaded tests both go to Intel by 8.4%.

The Intel chip also wins the Cinebench R23 multi-core test by 3.5%. That result is notable because it contradicts the R15 multi-core outcome, where AMD leads by 46.4%. The R23 test appears to reward the Intel architecture more than the older R15 test does.

The use-case split from the data is straightforward. For multithreaded integer work, compression, encryption, and extended instruction sets, the AMD Ryzen AI 5 340 is the stronger choice. For floating point math, physics simulation, prime number finding, and PassMark single-thread performance, the Intel Core 5 315 holds the advantage. The overall average score and the win tally favor AMD, but the Intel part has specific strengths that matter in the right workload.
