AMD Ryzen 5 7500X3D vs Intel Core i5-14450HX Comparison

Head-to-Head Benchmarks

The PassMark suite reveals a clear split between the AMD Ryzen 5 7500X3D and the Intel Core i5-14450HX. The AMD part wins 6 of the 11 recorded comparisons, while Intel takes 5, but the margins tell a more nuanced story than the raw win count. The largest single victory belongs to AMD in the prime number search test, where the Ryzen 5 7500X3D scores 221 against Intel's 98, a 125.5% advantage. This is not a marginal gap; it is the most decisive result in the entire head-to-head set and points to a fundamental strength in a specific workload type.

AMD also dominates in physics simulation, scoring 2779 versus 1475 for Intel, an 88.4% lead. Extended instruction performance follows the same pattern, with AMD at 20455 and Intel at 17207, a 18.9% advantage. Random string sorting goes to AMD by 11.6% (32999 versus 29565), and data encryption shows a narrower AMD win of 1.4% (15797 versus 15574). The multithreaded PassMark score also favors AMD, 25047 versus 23680, a 5.8% margin. These results indicate that the 3D V-Cache equipped chip excels in workloads that stress memory latency sensitivity and instruction-level parallelism.

Intel fights back in the remaining categories, and its wins are concentrated in arithmetic throughput. Floating point math shows Intel at 58037 versus 43594 for AMD, a 24.9% advantage. Integer math follows with Intel at 78330 versus 70774, a 9.6% lead. Data compression goes to Intel by a slim 2.5% margin (278538 versus 271649), and single-thread performance favors Intel by 4.1% (3643 versus 3494). The compression result is notable because it is Intel's only win in a memory-heavy workload, and even that margin is small.

The average benchmark scores place the two chips in different leagues entirely. AMD's average is 44573, while Intel's is 32040. That difference is driven by AMD's much higher scores in the PassMark integer, floating point, and multithread tests, despite Intel winning some individual categories. The percentile rankings reflect this: AMD sits at the 89th percentile of all CPUs, while Intel is at the 82nd. When placed against their nearest rivals, AMD's closest competitor is the Intel Core Ultra X9 388H at 44466 (a 0.2% difference), while Intel's nearest rival is the Intel Core i7-13705H at 32076 (a -0.1% difference). These proximity values show that each chip is tightly grouped with its own performance tier.

Where Each One Wins

The AMD Ryzen 5 7500X3D is the pick for physics-based simulations, prime number calculations, and extended instruction workloads. Its 88.4% lead in physics and 125.5% lead in prime numbers are not incremental improvements; they represent a different performance class for those specific tasks. The 18.9% edge in extended instructions and the 11.6% win in random string sorting reinforce the pattern: AMD's cache architecture delivers outsized gains when working sets fit in the 96 MB shared L3 cache. The multithread win of 5.8% also suggests that the 6-core, 12-thread design punches above its thread count in mixed workloads.

The Intel Core i5-14450HX takes the arithmetic categories. Its 24.9% lead in floating point math and 9.6% lead in integer math show that the 10-core, 16-thread configuration with higher boost clocks (4.80 GHz versus 4.50 GHz) translates directly into raw number crunching. The 4.1% single-thread advantage (3643 versus 3494) and the 2.5% compression win round out Intel's profile. For users whose primary metric is single-core responsiveness or pure math throughput, the Intel part has the edge.

The split is clean: AMD wins memory-latency-sensitive and instruction-diverse workloads; Intel wins raw arithmetic and single-thread speed. Neither chip dominates the other comprehensively, which makes the choice heavily dependent on the intended application mix.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses a 6-core, 12-thread configuration built on the Raphael design with Zen 4 cores, fabricated on TSMC's 5 nm process. The die size is 71 mm², and the transistor count is 11,270 million. Intel counters with a 10-core, 16-thread layout based on Raptor Lake-HX Refresh, built on Intel's 10 nm process with a 257 mm² die. The transistor count for Intel is not recorded in the database.

Cache organization is where the designs diverge sharply. AMD allocates 64 KB of L1 per core and 1 MB of L2 per core, but the defining feature is the 96 MB shared L3 cache. Intel uses 80 KB of L1 per core and 2 MB of L2 per core, with only 20 MB of shared L3. That 76 MB difference in L3 capacity is the single largest architectural gap between the two, and it explains AMD's dominance in cache-sensitive benchmarks like physics and prime numbers.

Memory support also differs. AMD supports DDR5 exclusively with a dual-channel bus and a recorded memory bandwidth of 83.2 GB/s. Intel supports both DDR4 and DDR5 on a dual-channel bus, but no memory bandwidth figure is recorded. Both support ECC memory. PCIe connectivity favors AMD with Gen 5 across 24 lanes, while Intel offers Gen 5 across 16 lanes. Integrated graphics differ as well: AMD pairs with Radeon Graphics, while Intel uses UHD Graphics 710.

Clock speeds tell the rest of the story. AMD runs a base clock of 4.00 GHz with a boost of 4.50 GHz, while Intel runs 2.40 GHz base and 4.80 GHz boost. Intel's higher boost clock supports its single-thread win, while AMD's higher base clock and larger cache support its multithread and latency-sensitive wins. Thermal design power is close: AMD is rated at 65 watts, Intel at 55 watts. The AMD processor is not multiplier unlocked, while the Intel part is. The AMD chip uses socket AM5, while Intel uses BGA 1964, reflecting Intel's mobile positioning.

The Verdict

The data supports a straightforward conclusion. Choose the AMD Ryzen 5 7500X3D for workloads dominated by physics simulation, prime number searches, extended instruction sets, and multithreaded general computing. Its 88.4% physics lead, 125.5% prime number lead, and 18.9% extended instruction advantage are decisive, and its 5.8% multithread win adds weight. The 89th percentile ranking and average score of 44573 place it in a higher overall performance tier than Intel's 82nd percentile and 32040 average.

Choose the Intel Core i5-14450HX for applications that prioritize single-thread speed, floating point math, and integer math. Its 4.1% single-thread edge, 24.9% floating point lead, and 9.6% integer lead are real, and the 10-core configuration with a 4.80 GHz boost clock delivers strong raw throughput. The 2.5% compression win is a smaller but still positive data point for Intel.

There is no universal winner. The AMD part is the better all-rounder by average score and percentile, but the Intel part wins the specific arithmetic categories where its higher boost clock and extra cores matter most. The 76 MB L3 cache difference is the primary driver of the performance split, and it is visible in every benchmark result.
