AMD Ryzen 7 PRO 5755G vs Intel Core i5-14600K Comparison

The AMD Ryzen 7 PRO 5755G and Intel Core i5-14600K represent two very different philosophies for desktop processing, with the former built on AMD’s efficient Zen 3 architecture for a mainstream socket and the latter being Intel’s high-core-count Raptor Lake flagship for enthusiasts. Benchmark data shows a decisive performance gap between the two, with the Intel chip winning every single head-to-head test in the Passmark suite. The Ryzen 7 PRO 5755G, however, still holds its own as a competent 8-core processor, offering a distinct set of trade-offs in platform features and power requirements that may sway certain users despite its lower raw throughput.

Where Each One Wins

The data is unambiguous: the Intel Core i5-14600K wins in every single benchmark category recorded in the head-to-head comparison. Across the eleven Passmark tests, the i5-14600K takes the top spot each time, leaving the Ryzen 7 PRO 5755G with zero wins. This is not a narrow victory either; the deltas are substantial, ranging from a 21.2% lead in single-threaded performance to a massive 64.2% advantage in the prime number finding test.

The i5-14600K’s most dominant areas are in compute-heavy workloads. In `passmark_find_prime_numbers`, the Intel chip scores 162 versus the AMD’s 58, representing a 64.2% delta. This suggests a significant advantage in integer-heavy, branch-predictive tasks. Similarly, in `passmark_physics`, the Intel part scores 2473 against 1022, a 58.7% lead, indicating a strong showing in simulated physics calculations. The Intel chip also excels in floating-point math, scoring 92794 compared to 50778 for the Ryzen, a 45.3% difference, and in multithreaded workloads, where it scores 38682 versus 23858, a 38.3% lead.

The Ryzen 7 PRO 5755G’s wins are not in performance, but in efficiency and platform cost. It has a TDP of 65 watts compared to the Intel’s 125 watts, making it a more power-frugal option. It also uses the older AMD Socket AM4 platform, which supports DDR4 memory, whereas the Intel chip supports both DDR4 and DDR5. While the Ryzen loses on performance, its lower power draw and potentially cheaper platform make it a viable choice for users prioritizing energy savings over speed.

The Verdict

The choice between these two processors is clear for performance-focused users. The Intel Core i5-14600K is the outright winner in every measurable benchmark. With 14 cores and 20 threads, it significantly outpaces the 8-core, 16-thread Ryzen in all multithreaded applications. The data shows a 38.3% lead in the Passmark multithread test, and its single-thread score of 4270 is 21.2% higher than the Ryzen’s 3366. For any workload that benefits from raw compute power—be it video rendering, software compilation, or complex simulations—the i5-14600K is the superior choice based on the benchmark results.

However, the Ryzen 7 PRO 5755G is not without merit. For users on a strict power budget or those building a system on the mature AM4 platform, it offers a capable 8-core experience. Its 65-watt TDP is nearly half that of the Intel’s 125-watt specification, which could translate to lower cooling requirements and quieter operation. The data shows it is a competent processor, sitting in the 90th percentile of all CPUs, but it is simply outclassed by the Intel part in this direct comparison. The verdict is that the Intel Core i5-14600K is for users who demand maximum performance, while the AMD Ryzen 7 PRO 5755G is for those who value platform maturity and lower power consumption over peak throughput.

Head-to-Head Benchmarks

The most lopsided result in the comparison is the `passmark_find_prime_numbers` test. The Intel Core i5-14600K achieves a score of 162, which is 64.2% higher than the AMD’s 58. This test is typically sensitive to integer arithmetic and cache latency, areas where the Intel’s hybrid architecture and larger cache appear to have a significant edge. The `passmark_physics` test shows a similar story, with the Intel chip scoring 2473 against the AMD’s 1022, a 58.7% differential, suggesting a major advantage in computationally intensive physics simulations.

Looking at broader workload categories, the Intel chip’s lead narrows but remains substantial. In `passmark_floating_point_math`, the i5-14600K scores 92794 versus 50778 for the Ryzen, a 45.3% advantage. For integer math, the scores are 125737 and 90270, respectively, a 28.2% lead for Intel. The `passmark_multithread` test shows Intel’s core count advantage paying off, with a score of 38682 compared to 23858, a 38.3% difference. Even in memory-sensitive tasks like `passmark_data_compression`, the Intel chip leads with 482020 against 295730, a 38.6% edge.

The single-threaded results are the closest, but Intel still wins. The i5-14600K scores 4270 in `passmark_single_thread` while the Ryzen 7 PRO 5755G scores 3366, a 21.2% lead for Intel. This indicates that even in lightly threaded applications, the Intel part’s higher boost clock of 5.30 GHz compared to the AMD’s 4.60 GHz gives it a distinct performance advantage. The data consistently shows that across all tested metrics, the Intel Core i5-14600K is the faster processor, with deltas ranging from 21.2% to 64.2%.
