AMD Ryzen 5 7500X3D vs Intel Core Ultra 5 235A Comparison

The AMD Ryzen 5 7500X3D and Intel Core Ultra 5 235A are both 65-watt desktop processors aimed at the mainstream segment, yet the recorded benchmark data shows two sharply contrasting performance profiles. The Intel part wins 10 of the 11 head-to-head tests, often by substantial margins, while the AMD chip secures a single, but decisive, victory in the physics workload. The data indicates that the choice between them depends entirely on whether the workload favors raw throughput or specific computational patterns.

Where Each One Wins

The Intel Core Ultra 5 235A dominates the majority of the PassMark test suite. Its largest advantage appears in floating-point math, where it scores 118778 against the AMD’s 43594, a delta of -63.3% from the AMD’s perspective. This pattern repeats across data compression (393800 vs 271649, -31%), data encryption (30136 vs 15797, -47.6%), and extended instructions (31625 vs 20455, -35.3%). The Intel processor also leads in multithreaded performance, scoring 38392 versus 25047, a -34.8% difference, and in single-thread performance, scoring 4557 versus 3494, a -23.3% difference. These results indicate a broad-based advantage in compute-heavy, parallel, and single-threaded tasks.

The AMD Ryzen 5 7500X3D wins only the physics test, scoring 2779 against Intel’s 2437, a 14% advantage. This is a notable outlier given the Intel chip’s otherwise comprehensive lead. The physics workload often stresses memory latency and cache behavior, which aligns with the AMD part’s large shared L3 cache. In this specific test, the AMD architecture delivers a measurable edge, but it does not translate into similar wins elsewhere in the suite. The data positions the 7500X3D as a specialized performer, while the 235A delivers more consistent results across varied workloads.

Architecture Differences

The two processors diverge fundamentally in their core configurations and silicon design. The AMD Ryzen 5 7500X3D uses 6 cores and 12 threads, built on the Raphael codename with a 5 nm process at TSMC. It integrates 11,270 million transistors on a 71 mm² die. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a substantial 96 MB of shared L3 cache. The Intel Core Ultra 5 235A, by contrast, uses 14 cores and 14 threads, based on the Arrow Lake architecture with a 3 nm process, also at TSMC. It packs 17,800 million transistors on a 243 mm² die. Its cache layout provides 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache.

The core count difference is stark: Intel offers more than double the physical cores, but no hyperthreading, resulting in 14 threads versus AMD’s 12 threads. The AMD processor compensates with a much larger L3 cache, 96 MB versus 24 MB, which likely explains its physics test win. The process nodes differ, with Intel using a 3 nm node versus AMD’s 5 nm node, and the Intel die is significantly larger at 243 mm² versus 71 mm². Both support DDR5 memory in dual-channel mode, but the Intel part provides higher memory bandwidth at 102.4 GB/s versus 83.2 GB/s. The AMD chip supports ECC memory, while the Intel chip does not. PCIe lane counts also differ, with AMD offering 24 Gen 5 lanes and Intel offering 20. Integrated graphics are present on both, with AMD using Radeon Graphics and Intel using Arc Xe-LPG Graphics 24EU. Neither processor has an unlocked multiplier, so overclocking is not an option for either.

Head-to-Head Benchmarks

The most one-sided result in the dataset is the floating-point math test. The Intel Core Ultra 5 235A scores 118778, which is 63.3% higher than the AMD Ryzen 5 7500X3D’s 43594. This is the largest percentage gap across all tests. Data encryption shows a similar trend, with Intel at 30136 versus AMD at 15797, a -47.6% difference. Extended instructions follow, with Intel at 31625 and AMD at 20455, a -35.3% gap. Multithread performance favors Intel at 38392 versus 25047, a -34.8% difference. Random string sorting also favors Intel, 49489 versus 32999, a -33.3% gap.

The Intel advantage narrows but remains significant in other tests. Data compression shows Intel at 393800 versus AMD at 271649, a -31% difference. Prime number finding favors Intel, 392 versus 221, a -43.6% gap. Integer math is the closest Intel win, with 88626 versus 70774, a -20.1% difference. Single-thread performance, recorded identically in both PassMark single-thread fields, favors Intel at 4557 versus 3494, a -23.3% gap.

The single AMD victory comes in the physics test, where the Ryzen 5 7500X3D scores 2779 against Intel’s 2437, a 14% advantage. This result is notable because it is the only test where the AMD chip leads, and it does so despite the Intel chip’s higher core count and clock speed. The physics benchmark appears to respond well to the AMD’s large L3 cache, which suggests a specific workload characteristic rather than a general performance advantage.

The Verdict

The recorded data shows that the Intel Core Ultra 5 235A is the stronger overall performer, winning 10 of 11 head-to-head tests. Its advantages span single-thread, multithread, encryption, compression, and math workloads, with margins ranging from -20.1% to -63.3%. The Intel chip also achieves a higher average benchmark score of 48201, compared to 44573 for the AMD, and sits at the 90th percentile versus the AMD’s 89th. The Intel processor’s 14 cores, higher boost clock, and larger memory bandwidth contribute to this broad lead.

The AMD Ryzen 5 7500X3D is the choice for the physics workload specifically, where its 14% win indicates a unique strength. Its 96 MB of L3 cache and 6-core, 12-thread configuration do not produce wins elsewhere in the suite. The AMD chip’s lower scores in floating-point math (-63.3%) and multithread (-34.8%) show clear limitations outside its niche. For workloads that resemble the physics test, the AMD part has a measurable edge. For everything else in the dataset, the Intel Core Ultra 5 235A delivers higher scores. The data does not support a general recommendation for the AMD processor; it excels only in a narrow scenario, while the Intel processor provides superior results across the majority of measured tasks.
