AMD Ryzen 5 7500X3D vs Intel Core Ultra 5 245HX Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive overall win for the Intel Core Ultra 5 245HX, which claims 10 of the 11 shared benchmark comparisons. The AMD Ryzen 5 7500X3D takes a single victory. The average benchmark score for the Intel part is 48,287, compared to 44,573 for the AMD part, a difference that places the Intel chip at the 90th percentile of all CPUs versus the 89th percentile for the AMD chip.

The largest margin in the entire comparison appears in floating point math. The Intel Core Ultra 5 245HX scores 120,735 against the AMD Ryzen 5 7500X3D's 43,594, a 63.9% gap. This is the single biggest win for either processor and indicates a substantial advantage in workloads that rely heavily on floating point throughput. Integer math tells a similar story, though with a smaller margin: Intel scores 92,150 versus AMD's 70,774, a 23.2% difference.

Data compression and encryption workloads also favor Intel heavily. In data compression, Intel posts 393,071 against AMD's 271,649, a 30.9% lead. In data encryption, Intel scores 30,022 versus 15,797, a 47.4% advantage. Extended instruction workloads follow the same pattern, with Intel at 31,212 and AMD at 20,455, a 34.5% gap. Random string sorting shows Intel ahead by 30.7%, with scores of 47,616 and 32,999 respectively.

The multi-threaded PassMark score reinforces the trend. Intel records 38,069 while AMD records 25,047, a 34.2% difference. Prime number finding, a workload sensitive to integer throughput and core count, shows Intel at 359 versus AMD's 221, a 38.4% lead. Single-thread performance also favors Intel: 4,481 versus 3,494, a 22% gap. Both the "passmark_single_thread" and "passmark_singlethread" fields confirm the same result.

The AMD Ryzen 5 7500X3D claims one clear win: the physics test. AMD scores 2,779 against Intel's 2,526, a 10% advantage. This is the only benchmark in the head-to-head set where AMD finishes ahead, and the margin is modest compared to the large gaps Intel produces elsewhere. The physics result suggests a specific workload where AMD's architecture retains an edge, but it stands alone in an otherwise one-sided comparison.

When placed against their respective nearest rivals in the database, both processors sit close to their peers. The AMD chip's average score of 44,573 is 0.2% above the Intel Core Ultra X9 388H (44,466), 0.5% above the Intel Core i9-13950HX (44,342), and 0.6% above the AMD Ryzen AI Max 385 (44,309), while trailing the Intel Core i5-14600 (44,889) by 0.7%. The Intel Core Ultra 5 245HX's average of 48,287 is 0.2% above the Intel Core Ultra 5 235A (48,201) and the AMD Ryzen AI Max PRO 380 (48,171), while trailing the AMD EPYC 4345P (48,470) by 0.4% and the Intel Core i5-14600K (48,618) by 0.7%. These near-neighbor margins are small, indicating that both processors sit in tightly contested performance bands relative to their closest alternatives.

The Verdict

The benchmark data directs a clear verdict. The Intel Core Ultra 5 245HX is the stronger processor in the majority of measured workloads, and in several cases the margin is large. The 63.9% lead in floating point math is the standout result, but the 47.4% gap in data encryption and the 34.2% gap in multi-threaded performance are also substantial. Any workload that scales with core count, thread count, or raw throughput will favor the Intel part.

The AMD Ryzen 5 7500X3D wins the physics benchmark by 10%, but that single result does not offset the breadth of Intel's wins. For users prioritizing the physics-style workload, AMD has a measurable but narrow advantage. For everything else in the recorded benchmark set, Intel is ahead, often by wide margins.

The percentile data places the Intel part at 90% versus 89% for AMD, a small overall ranking difference that understates the size of the head-to-head deltas in specific tests. The average benchmark score difference of 3,714 points (48,287 versus 44,573) is more representative of the overall performance gap. The Intel Core Ultra 5 245HX is the recommended choice based strictly on the recorded measurements, with the caveat that the AMD part retains a specific physics workload advantage.

Where Each One Wins

The Intel Core Ultra 5 245HX wins in every category except physics. Its largest advantages are in floating point math (63.9% ahead), data encryption (47.4% ahead), and prime number finding (38.4% ahead). These results point to workloads involving numerical computation, cryptographic operations, and integer-heavy algorithms. The multi-threaded score advantage of 34.2% suggests that parallel workloads, such as rendering, compilation, or data processing, will see meaningful gains on the Intel part. Single-thread performance is also 22% higher, which benefits applications that rely on a single core's speed.

The AMD Ryzen 5 7500X3D wins the physics benchmark by 10%. This is a narrow margin, but it identifies a specific area where the AMD architecture performs better. Physics simulations often involve a mix of integer and floating point operations with irregular memory access patterns, and the data indicates AMD handles this particular mix more efficiently. The AMD part also has a larger L3 cache (96 MB shared versus 24 MB shared), which may contribute to its physics result, though the recorded data does not directly measure cache sensitivity.

The use-case split is therefore clear: Intel for general throughput, multi-threaded work, encryption, compression, and single-thread performance; AMD for physics-style workloads where its 10% edge applies. The Intel part's 14 cores versus AMD's 6 cores, and 14 threads versus 12 threads, align with its multi-threaded dominance, though the thread count difference is smaller than the core count difference since Intel does not use hyper-threading in this part.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen 5 7500X3D is part of the 7000 series, uses the Raphael codename, and belongs to the Zen 4 (Raphael) generation. It is built on a 5 nm process at TSMC with 11,270 million transistors on a 71 mm² die. The Intel Core Ultra 5 245HX is part of the Core Ultra Series 2, uses the Arrow Lake architecture with the Arrow Lake-HX codename, and is built on a 3 nm process at TSMC with 17,800 million transistors on a 243 mm² die.

Core and thread counts differ substantially. The AMD part has 6 cores and 12 threads, while the Intel part has 14 cores and 14 threads. The Intel part does not use simultaneous multi-threading, so its thread count equals its core count. The AMD part uses SMT, giving it 12 threads from 6 cores. Cache configurations also differ: AMD has 64 KB of L1 per core, 1 MB of L2 per core, and 96 MB of shared L3. Intel has 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3. The AMD L3 cache is four times larger than Intel's.

Memory support is DDR5 for both, with dual-channel buses, but the memory bandwidth differs: AMD lists 83.2 GB/s while Intel lists 102.4 GB/s. AMD supports ECC memory, while Intel does not. PCIe support also differs: AMD offers Gen 5 with 24 lanes (CPU only), while Intel offers Gen 5 with 20 lanes (CPU only). Integrated graphics differ as well: AMD uses Radeon Graphics, while Intel uses Arc Xe-LPG Graphics with 48 execution units.

The process node difference (5 nm for AMD versus 3 nm for Intel) and the transistor count difference (11,270 million versus 17,800 million) reflect the Intel part's larger, denser design. The die size difference (71 mm² versus 243 mm²) is substantial, with Intel occupying more than three times the silicon area.

The market segments also differ, with AMD listed as Desktop and Intel listed as Mobile. The release dates are about ten months apart: AMD released on 2025-11-11, while Intel released on 2025-01-12.

The AMD part has a launch MSRP of $269, while the Intel part has no recorded launch MSRP. The multiplier unlock status differs: the AMD multiplier is locked, while the Intel multiplier is unlocked. The part numbers are different: AMD uses 100-000001904, while Intel uses SRVFM. Production status is Active for both.

The core, thread, cache, memory bandwidth, ECC support, PCIe lane count, integrated graphics, process node, transistor count, and die size differences are all covered in the architecture section. The remaining specification differences, namely clocks, TDP, socket, market segment, release date, MSRP presence, multiplier lock, and part number, complete the comparison.
