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

Head-to-Head Benchmarks

The head-to-head results present a lopsided contest. The AMD Ryzen 5 7500X3D wins eight of the eleven benchmark comparisons, while the Intel Core i5-14400T takes only three. The margins, however, tell a more interesting story than the win count alone.

The most dramatic victory for the AMD processor comes in the PassMark find prime numbers test. The Ryzen 5 7500X3D scores 221 against the Intel chip's 73, a 202.7 percent advantage. This is not a subtle difference; the AMD part is more than three times faster in this specific workload. A similar, though less extreme, pattern emerges in the physics test, where the AMD chip scores 2779 versus 1244, a 123.4 percent lead. These two results suggest a fundamental advantage in computationally intense, integer-heavy single-threaded work.

The extended instructions benchmark shows another sizable gap. The Ryzen 5 7500X3D posts 20455, which is 40.5 percent ahead of the Intel chip's 14562. Data encryption also favors AMD, with scores of 15797 and 13244 respectively, a 19.3 percent margin. Random string sorting goes to AMD by 31 percent, with scores of 32999 and 25181. These results indicate that the AMD processor handles algorithmic and encryption workloads with considerably more headroom.

Multi-threaded performance reinforces the AMD advantage. The PassMark multithread score for the Ryzen 5 7500X3D is 25047, while the Intel Core i5-14400T manages 20223. That is a 23.9 percent difference. Notably, the AMD chip achieves this despite having fewer cores: six cores and twelve threads versus the Intel chip's ten cores and sixteen threads. Data compression follows the same pattern, with AMD at 271649 and Intel at 235636, a 15.3 percent lead. Integer math rounds out the AMD wins with 70774 versus 65667, a 7.8 percent margin.

The Intel Core i5-14400T claims its victories in floating-point math and single-thread tests. The floating-point math score is 49139 for Intel, which is 11.3 percent higher than the AMD score of 43594. This is the largest Intel win and the only workload where the margin exceeds ten percent. The single-thread results are nearly identical: Intel scores 3512 and AMD scores 3494, a 0.5 percent difference in Intel's favor. Both the single-thread and single-thread duplicate entries show the same numbers, confirming the consistency of that measurement.

The average benchmark scores place these processors in different tiers. The AMD Ryzen 5 7500X3D has an average score of 44573, while the Intel Core i5-14400T averages 27166. The AMD chip sits at the 89th percentile among all CPUs, while the Intel chip is at the 79th. The nearest rivals for the AMD part include the Intel Core Ultra X9 388H at 44466 (0.2 percent behind) and the Intel Core i5-14600 at 44889 (0.7 percent ahead). The Intel chip's closest competition includes the Intel Core i9-9900K at 27097 (0.3 percent behind) and the AMD Ryzen 7 5700G at 27051 (0.4 percent behind). These peer groups show that the AMD chip competes with high-end mobile and desktop parts, while the Intel chip sits closer to older flagship and mid-range hardware.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 7500X3D is built on the Raphael codename, part of the Zen 4 (Raphael) generation in the 7000 series. The Intel Core i5-14400T uses the Raptor Lake-R codename, part of the Raptor Lake Refresh generation in the Core 14th Gen lineup.

Manufacturing processes diverge sharply. The AMD chip uses a 5 nm process at TSMC, while the Intel chip uses a 10 nm process at Intel's own foundry. The transistor counts reflect this difference in density. The AMD processor contains 11,270 million transistors on a 71 mm² die. The Intel processor's transistor count is not recorded, but its die size is much larger at 215 mm². The smaller, denser AMD die pairs with a massive cache configuration: 96 MB of shared L3 cache. The Intel chip has only 20 MB of shared L3 cache. Per-core cache also differs, with AMD providing 64 KB of L1 and 1 MB of L2 per core, while Intel provides 80 KB of L1 and 1.25 MB of L2 per core.

Core and thread counts favor Intel on paper. The Intel Core i5-14400T has 10 cores and 16 threads, while the AMD Ryzen 5 7500X3D has 6 cores and 12 threads. Clock speeds tell a more nuanced story. Both processors boost to 4.50 GHz. The base clocks, however, are far apart: the AMD chip runs at 4.00 GHz base, while the Intel chip runs at 1.50 GHz base. The Intel chip's low base clock is typical of a T-series low-power part, and it explains part of the performance gap in sustained workloads.

Thermal design power differs by a wide margin. The AMD Ryzen 5 7500X3D is rated at 65 W TDP, while the Intel Core i5-14400T is rated at 35 W TDP. The sockets are incompatible: AMD uses Socket AM5, and Intel uses Socket 1700. Memory support also separates them. The AMD chip supports DDR5 only, while the Intel chip supports both DDR4 and DDR5. Both use dual-channel memory buses. The AMD chip has a recorded memory bandwidth of 83.2 GB/s, while the Intel chip's bandwidth is not recorded. Both support ECC memory.

PCIe connectivity is another differentiator. The AMD chip provides Gen 5 with 24 lanes (CPU only), while the Intel chip provides Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well: the AMD chip includes Radeon Graphics, and the Intel chip includes UHD Graphics 730. Neither processor has an unlocked multiplier.

Release timing also differs. The Intel Core i5-14400T was released on 2024-01-07, while the AMD Ryzen 5 7500X3D was released on 2025-11-11. The AMD part numbers are 100-000001904 for AMD and SRN3N for Intel.

The Verdict

The data paints a clear picture of two processors aimed at different priorities. The AMD Ryzen 5 7500X3D dominates in eight of eleven benchmark comparisons, with wins that range from 7.8 percent in integer math to 202.7 percent in prime number finding. Its average benchmark score of 44573 is 64 percent higher than the Intel chip's 27166. The AMD processor also claims the 89th percentile ranking among all CPUs, ten points above the Intel chip's 79th percentile.

The Intel Core i5-14400T holds two genuine advantages. It wins floating-point math by 11.3 percent, and it edges out the AMD chip in single-thread performance by 0.5 percent. It also uses less power, with a 35 W TDP versus 65 W, and supports both DDR4 and DDR5 memory, which gives platform flexibility. Its lower launch MSRP of $221 versus $269 reflects its position in the market.

The nearest rival comparisons reinforce the separation. The AMD chip's closest competitors, such as the Intel Core Ultra X9 388H and Intel Core i5-14600, are higher-tier parts with average scores above 44000. The Intel chip's closest rivals, including the Intel Core i9-9900K and AMD Ryzen 7 5700G, average around 27000. The AMD chip occupies a higher performance class entirely.

Where Each One Wins

The AMD Ryzen 5 7500X3D wins in workloads that stress algorithmic processing, encryption, and multi-threaded throughput. Its 202.7 percent lead in prime number finding and 123.4 percent lead in physics indicate strong integer execution. The 40.5 percent advantage in extended instructions and 19.3 percent advantage in data encryption make it the better choice for cryptography and instruction-heavy tasks. Multi-threaded applications, reflected in the 23.9 percent multithread win and 15.3 percent data compression win, also favor the AMD chip. Its 96 MB of shared L3 cache and 5 nm process likely contribute to these results, though the recorded data only confirms the outcomes.

The Intel Core i5-14400T wins in floating-point math, where its 49139 score beats the AMD chip by 11.3 percent. Single-thread performance is essentially tied, with Intel ahead by just 0.5 percent, scoring 3512 versus 3494. The Intel chip's 10 cores and 16 threads may appeal in scenarios where thread count matters more than raw per-thread speed, but the benchmark results do not show a multi-threaded win for Intel. Its 35 W TDP and support for DDR4 and DDR5 memory make it a more flexible platform option, though the recorded data does not quantify power efficiency beyond the TDP figures.

The overall benchmark evidence favors the AMD Ryzen 5 7500X3D for compute-heavy tasks. The Intel Core i5-14400T remains competitive in floating-point operations and offers a near-parity single-thread experience, but the AMD chip's dominance across most measured workloads, combined with its higher percentile ranking and average score, establishes it as the stronger processor in the recorded data.
