Where Each One Wins

The benchmark data splits decisively. The Intel Core Ultra 5 235HX takes 10 of 11 head-to-head tests, and the AMD Ryzen 5 7500X3D takes exactly one. The Intel CPU wins in data compression, encryption, extended instructions, prime number finding, floating-point math, integer math, multithreaded workloads, random string sorting, and single-thread performance. The AMD part wins only in the physics test, with a 9% margin. That physics result is a narrow but clear signal of where the 3D V-Cache layout helps.

For workloads that stress raw compute throughput, the Intel Core Ultra 5 235HX is the dominant part. The multithread score of 40,849 versus 25,047 shows a massive gap. The single-thread score of 4,683 versus 3,494 also favors Intel. Applications that rely on cache-heavy, latency-sensitive physics calculations favor the AMD Ryzen 5 7500X3D, but that is the only area where the AMD part leads in this dataset.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 7500X3D is a 6-core, 12-thread desktop part from the 7000 series, codenamed Raphael, built on a 5 nm process at TSMC with 11,270 million transistors on a 71 mm² die. It uses Zen 4 architecture. The Intel Core Ultra 5 235HX is a 14-core, 14-thread mobile part from Core Ultra Series 2, codenamed Arrow Lake-HX, built on a 3 nm process at TSMC with 17,800 million transistors on a 243 mm² die. It uses Arrow Lake architecture.

The AMD part has a much larger L3 cache at 96 MB shared, versus 24 MB shared on the Intel. That large L3 is characteristic of the 3D V-Cache design and explains the physics benchmark win. The Intel part has smaller L3 but larger per-core L1 (192 KB versus 64 KB) and L2 (3 MB versus 1 MB) allocations. The process node difference is significant: 3 nm versus 5 nm, both from TSMC. The Intel die is more than three times larger by area, reflecting the higher core count and integrated Arc Xe-LPG Graphics 48EU.

Memory bandwidth also differs. The Intel Core Ultra 5 235HX records 102.4 GB/s, while the AMD Ryzen 5 7500X3D records 83.2 GB/s. The Intel part runs on a BGA 2114 socket for mobile systems, while the AMD part uses AM5 for desktops. The AMD CPU includes Radeon Graphics as integrated graphics, and the Intel uses Arc Xe-LPG Graphics 48EU.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen 5 7500X3D has 6 cores and 12 threads; the Intel Core Ultra 5 235HX has 14 cores and 14 threads. The AMD base clock is 4.00 GHz with a 4.50 GHz boost, while the Intel base clock is 2.90 GHz with a 5.10 GHz boost. The AMD TDP is 65 watts, the Intel TDP is 55 watts.

The AMD part uses AMD Socket AM5; the Intel uses Intel BGA 2114. The process nodes differ: 5 nm for AMD, 3 nm for Intel, both from TSMC. Transistor counts are 11,270 million for AMD and 17,800 million for Intel. Die sizes are 71 mm² and 243 mm² respectively.

Cache layouts diverge sharply. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 96 MB shared L3. Intel uses 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. Memory bandwidth favors Intel at 102.4 GB/s versus 83.2 GB/s. ECC memory support exists only on the AMD part. PCIe lane counts differ: 24 lanes for AMD, 20 for Intel, both Gen 5 CPU-only.

The AMD processor has a launch MSRP of $269. The Intel part has no recorded launch MSRP in the database. The AMD multiplier is locked; the Intel multiplier is unlocked. Release dates differ: the AMD part released on 2025-11-11, the Intel on 2025-01-12. The AMD part number is 100-000001904, the Intel is SRVFL.

Head-to-Head Benchmarks

The largest Intel win is in floating-point math. The Core Ultra 5 235HX scores 129,819 versus 43,594 for the Ryzen 5 7500X3D, a 66.4% margin. That is the single biggest gap in the dataset. Integer math shows a smaller but still clear Intel advantage: 97,177 versus 70,774, a 27.2% difference.

Data compression heavily favors Intel: 426,417 versus 271,649, a 36.3% lead. Data encryption shows an even larger relative gap: 32,697 versus 15,797, a 51.7% difference. Extended instructions score 34,808 for Intel versus 20,455 for AMD, a 41.2% gap. Prime number finding records 361 for Intel versus 221 for AMD, a 38.8% difference. Random string sorting goes to Intel at 50,929 versus 32,999, a 35.2% margin.

Multithreaded performance is a clear Intel win: 40,849 versus 25,047, a 38.7% gap. Single-thread performance also favors Intel: 4,683 versus 3,494, a 25.4% difference. The physics test is the sole AMD victory: 2,779 versus 2,550, a 9% margin. That physics win is consistent with the larger L3 cache on the AMD part, which reduces latency for certain calculation patterns.

The average benchmark scores reflect the overall balance. The Intel Core Ultra 5 235HX averages 52,073, while the AMD Ryzen 5 7500X3D averages 44,573. The Intel part sits near rivals like the AMD EPYC 8124P (52,121, a 0.1% difference) and the Intel Core i7-14700 (52,301, a 0.4% difference). The AMD part sits near the Intel Core Ultra X9 388H (44,466, a 0.2% difference) and the Intel Core i9-13950HX (44,342, a 0.5% difference).

The Verdict

The data points to a clear performance hierarchy. The Intel Core Ultra 5 235HX wins 10 of 11 benchmark comparisons and holds a higher average score, a higher single-thread score, and a higher multithread score. The AMD Ryzen 5 7500X3D wins only the physics test, and even that margin is modest at 9%.

For desktop builders who prioritize raw compute across compression, encryption, math, and multithreaded workloads, the Intel Core Ultra 5 235HX is the stronger choice based on recorded measurements. Its 14 cores and higher boost clock translate directly into benchmark dominance. The AMD part, with its 6 cores and 96 MB L3 cache, shows a specific advantage in physics simulation, which suggests a niche for cache-sensitive single-threaded or latency-bound tasks.

The AMD Ryzen 5 7500X3D has a launch MSRP of $269. The Intel part has no launch MSRP recorded. The AMD part supports ECC memory and uses a desktop socket, while the Intel part is mobile-only with an unlocked multiplier. Those platform differences matter for system design, but in raw benchmark terms, the Intel Core Ultra 5 235HX is ahead in nearly every measured category. The verdict from the database is straightforward: Intel wins the compute tests, AMD wins one physics workload, and the choice depends on whether that physics result outweighs the other ten benchmark losses.
