AMD EPYC 4364P vs Intel Core i7-14700HX Comparison

AMD EPYC 4364P and Intel Core i7-14700HX are near-perfect statistical twins in the aggregate benchmark database, with average scores of 45970 and 45953 respectively. This places both at the 89th percentile of all CPUs, and their closest rival, the AMD EPYC 7303, sits at 45960 with a 0% delta. The head-to-head results, however, reveal a fascinating split: the Intel mobile part wins 12 of 17 benchmark comparisons, while the AMD server chip takes 5, with the margins swinging dramatically in both directions depending on the workload.

Head-to-Head Benchmarks

The most decisive victory in the entire comparison belongs to the AMD EPYC 4364P in Cinebench R23 single-core, where it scores 4177 against Intel’s 2103, a 98.6% advantage. This is not a marginal lead; it is nearly double the performance. The same pattern appears in Cinebench R15 single-core, with AMD winning 420 to 296 (41.9% ahead). These results indicate that the Zen 4 architecture’s high clock speeds translate directly into exceptional single-threaded rendering performance.

Intel’s counterattack comes in Cinebench R15 multi-core, where it scores 3812 versus AMD’s 2982, a 21.8% lead. This is the largest multi-core win for Intel in the Cinebench suite. However, the picture reverses in Cinebench R23 multi-core, where AMD takes a 20.3% victory with 29589 against Intel’s 24595. The inconsistency between Cinebench versions suggests that the workloads scale differently across the two architectures, with AMD’s advantage growing in the newer R23 test.

In Cinebench R20, Intel wins both tests by 4.8%, scoring 13059 in multi-core and 1843 in single-core, compared to AMD’s 12427 and 1754. This creates an unusual situation where Intel wins R15 and R20 single-core, but AMD wins R23 single-core by an enormous margin. The data shows no consistent single-threaded winner across all Cinebench versions.

The PassMark suite provides a different perspective. Intel dominates in floating-point math, scoring 93836 against AMD’s 66946, a 28.7% lead. It also wins integer math by 17.9% (131296 vs 107775) and physics by 20.7% (2252 vs 1785). Intel’s multithread score of 36566 beats AMD’s 33883 by 7.3%, and its single-thread score of 3947 beats AMD’s 3619 by 8.3%.

AMD fights back in the PassMark extended instructions test with 31605 versus 25718, a 22.9% win. It also edges out Intel in find prime numbers (177 vs 165, a 7.3% lead). The remaining PassMark tests are closer: Intel wins data compression by 6.9% (438539 vs 408220), data encryption by 7.4% (26092 vs 24174), and random string sorting by a razor-thin 0.4% (48544 vs 48344).

The Verdict

The data points to a clear division of labor. The AMD EPYC 4364P is the superior choice for single-threaded rendering workloads, particularly in Cinebench R23, where its 98.6% lead over Intel is decisive. This processor also shows strength in extended instruction workloads and prime number calculations, suggesting it handles specialized computation efficiently.

The Intel Core i7-14700HX is the better option for general-purpose multi-threaded performance across the PassMark suite, winning 12 of 17 benchmarks overall. Its advantages in floating-point math, integer math, and physics indicate strong raw compute capabilities. The Intel part also wins the two most recent Cinebench multi-core tests by 21.8% and 4.8%, though it loses the R23 multi-core test by 20.3%.

Considering the aggregate scores, the two processors are functionally equivalent for average workloads, with less than 0.1% separating their overall benchmark averages. The choice should depend on specific workload priorities: single-threaded rendering favors AMD, while mixed math and physics workloads favor Intel.
