AMD Ryzen 5 7500X3D vs Intel Core i5-14400 Comparison

Head-to-Head Benchmarks

The recorded data presents a split decision between the AMD Ryzen 5 7500X3D and the Intel Core i5-14400. Intel claims seven benchmark wins, while AMD takes four. The margins, however, tell a more nuanced story than the raw win count suggests.

The largest single victory belongs to AMD in the passmark_find_prime_numbers test. The Ryzen 5 7500X3D scores 221 against Intel's 80, a delta of 176.3%. This is an enormous gap, indicating that AMD's architecture handles this particular workload with exceptional efficiency. The physics test also favors AMD decisively: 2779 versus 1396, a 99.1% advantage. These two wins alone demonstrate that the AMD chip has specific strengths in certain computational patterns.

Intel's wins are concentrated in other areas. The floating_point_math test shows Intel at 61549 versus AMD's 43594, a 29.2% lead. Integer math also goes to Intel: 82017 versus 70774, a 13.7% margin. Data compression shows Intel at 314995 versus 271649, a 13.8% advantage. The single_thread test gives Intel a 3741 to 3494 win, a 6.6% edge.

Some tests are remarkably close. The multithread score is nearly identical: Intel at 25080, AMD at 25047, a delta of just 0.1%. This near-tie suggests that in broadly parallel workloads, the two processors deliver essentially equivalent throughput. Random string sorting is also close, with AMD edging ahead 32999 to 32346, a 2% margin. Extended instructions favor AMD at 20455 versus 19816, a 3.2% lead. Data encryption goes to Intel at 16731 versus 15797, a 5.6% difference.

The aggregate picture shows a processor that wins by huge margins in some tests and loses by moderate margins in others. AMD's physics score is nearly double Intel's, and its prime number finding is almost triple. Intel's largest win, floating point math, is a 29.2% gap, which is substantial but not as extreme as AMD's top victories. The average benchmark scores reflect this: AMD sits at 44573, while Intel sits at 32115. That difference is driven by AMD's inclusion in the database only having PassMark results, while Intel also has Cinebench and Geekbench scores that drag its average down. The percentile rankings place AMD at 89 versus Intel's 82.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses the Raphael codename, part of the Zen 4 generation built on a 5 nm process at TSMC. Intel counters with Raptor Lake-R, part of the Core 14th Gen Raptor Lake Refresh, built on a 10 nm process at Intel. The process node difference is significant: 5 nm versus 10 nm gives AMD a density and efficiency advantage that shows up in certain workloads.

Core counts differ considerably. AMD fields 6 cores and 12 threads, while Intel offers 10 cores and 16 threads. Intel uses a hybrid configuration typical of Raptor Lake, though the database does not specify the performance-core/efficiency-core split. AMD's 6 cores are all full Zen 4 cores, while Intel's 10 cores include a mix that allows it to present more threading capacity.

Cache configurations diverge sharply. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and a massive 96 MB of shared L3 cache. Intel provides 80 KB of L1 per core, 1.25 MB of L2 per core, and only 20 MB of shared L3. The 76 MB difference in L3 is the defining architectural distinction. This large pool of cache on the AMD part explains its dominance in cache-sensitive workloads like prime number finding and physics calculations.

Clock speeds show Intel with a higher boost: 4.70 GHz versus AMD's 4.50 GHz. AMD's base clock is higher at 4.00 GHz versus Intel's 2.50 GHz. Both processors carry a 65 watt TDP. The die sizes reflect the process difference: AMD measures 71 mm² with 11,270 million transistors, while Intel measures 215 mm² with no transistor count recorded. AMD's smaller die on a denser process allows it to pack the large cache without ballooning the physical footprint.

Memory support differs. AMD supports only DDR5, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses. AMD records a memory bandwidth of 83.2 GB/s, while Intel's bandwidth is not listed. Both support ECC memory. PCIe capabilities also differ: AMD provides Gen 5 with 24 lanes from the CPU, while Intel provides Gen 5 with 16 lanes from the CPU. Integrated graphics differ as well, with AMD using Radeon Graphics and Intel using UHD Graphics 730.

The sockets are incompatible: AMD uses Socket AM5, Intel uses Socket 1700. Neither processor has an unlocked multiplier. Release dates place Intel earlier at January 2024 and AMD later at November 2025. Market segments are both Desktop, and both are Active in production.

Where Each One Wins

The data points toward distinct use cases for each processor. AMD's wins in find_prime_numbers and physics suggest workloads that depend heavily on cache access patterns and latency-sensitive operations. The 176.3% lead in prime finding and 99.1% lead in physics are not marginal advantages; they indicate a fundamental superiority in these specific computational patterns. Random string sorting also favors AMD, though by a smaller 2% margin, and extended instructions favor AMD by 3.2%.

Intel's wins cover a broader set of general-purpose tasks. Floating point math at 29.2% ahead, integer math at 13.7% ahead, and data compression at 13.8% ahead show strength in numerically intensive and data-heavy operations. Single-thread performance at 6.6% ahead suggests Intel has the edge in lightly threaded applications that rely on single-core responsiveness. Data encryption at 5.6% ahead rounds out Intel's advantages.

The near-tie in multithread performance is instructive. Despite Intel having 4 more cores and 4 more threads, the multithread scores are essentially identical. This indicates that AMD's 96 MB cache and 5 nm process efficiency compensate for the core count disadvantage in broadly parallel workloads. The physics test, however, shows that AMD's advantage compounds when the workload has specific characteristics that favor its cache layout.

Users running simulation software, physics engines, or prime-number-based cryptographic workloads would see dramatic gains from the AMD part. Users running spreadsheet calculations, compression tasks, or floating-point-heavy scientific computations would prefer the Intel part. The single-thread advantage for Intel matters for older software that does not scale across cores.

The Verdict

The data supports different picks depending on workload priorities. The AMD Ryzen 5 7500X3D delivers exceptional results in cache-sensitive and physics-based workloads, with a 176.3% lead in prime number finding and a 99.1% lead in physics. Its 96 MB of L3 cache is the clear differentiator. The processor also matches Intel in multithread performance despite fewer cores, and it achieves an 89th percentile ranking across all CPUs.

The Intel Core i5-14400 offers broader general-purpose strength. It leads in floating point math by 29.2%, integer math by 13.7%, data compression by 13.8%, and single-thread performance by 6.6%. Its 82nd percentile ranking is lower than AMD's, but its benchmark portfolio includes Cinebench and Geekbench results that AMD lacks, making direct average comparisons imperfect.

For users whose workloads resemble the physics and prime number tests, the AMD part is the clear choice. The margins are too large to ignore. For users with mixed workloads that include floating point math, integer math, and compression, the Intel part delivers more consistent advantages. The multithread near-tie means neither processor offers a meaningful edge in heavily threaded general computing.

The choice ultimately hinges on whether the workload is cache-dominated or compute-dominated. The data indicates AMD for the former and Intel for the latter.
