Intel's percentile rank among all CPUs is 90, while AMD sits at 73. The nearest rival comparisons reinforce the positioning: AMD's closest competitor, the Intel Core Ultra 5 226V, scores 19368, a 0 percent delta, showing the Ryzen part is competitive with that chip. Intel's nearest rival, the Core Ultra 5 235A, scores 48201, a 0.2 percent delta, confirming the 245HX sits in a higher performance tier.

Architecture Differences

The two processors come from fundamentally different design generations. AMD uses Zen 3+ architecture, codenamed Rembrandt-R, fabricated on a 6 nm TSMC process with a die size of 208 mm². Intel uses Arrow Lake architecture, specifically Arrow Lake-HX, built on a 3 nm TSMC process with a die size of 243 mm² and 17,800 million transistors. Intel's process node advantage is three full generations ahead in lithography.

Core counts differ substantially. AMD provides 6 cores and 12 threads, while Intel provides 14 cores and 14 threads. Intel's thread count equals its core count, indicating the absence of Hyper-Threading in this configuration. AMD's thread count doubles its core count, enabling simultaneous multithreading. The base clocks are close: 3.30 GHz for AMD versus 3.10 GHz for Intel. Boost clocks favor Intel significantly: 5.10 GHz versus 4.40 GHz.

Cache hierarchies show Intel's larger allocation. AMD uses 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. Intel uses 192 KB L1 per core, 3 MB L2 per core, and 24 MB shared L3. Intel's per-core L2 is six times larger, and the shared L3 is 50 percent larger. Memory bandwidth reflects this: Intel records 102.4 GB/s versus AMD's 76.8 GB/s, both using dual-channel DDR5.

PCIe support differs by generation. AMD provides Gen 4 with 20 lanes (CPU only). Intel provides Gen 5 with 20 lanes (CPU only), doubling the per-lane bandwidth potential for attached devices. Integrated graphics also differ: AMD uses Radeon 660M, Intel uses Arc Xe-LPG Graphics with 48 execution units. Power envelopes diverge: AMD has a 35 W TDP, Intel has a 55 W TDP. Intel also offers an unlocked multiplier, while AMD does not. Sockets are proprietary to each vendor: AMD Socket FP7 versus Intel BGA 2114.

Where Each One Wins

Intel wins every recorded benchmark category, so the use-case split is straightforward. For workloads that stress floating-point math, encryption, extended instructions, or prime number generation, the Intel part delivers outsized advantages. The 77 percent lead in floating-point math and 64.3 percent lead in encryption indicate strong SIMD and cryptographic acceleration. Physics simulation, which relies on floating-point throughput, shows a 67.5 percent advantage for Intel.

For single-threaded responsiveness, Intel leads by 38.9 percent in PassMark single-thread and by 62 percent in Cinebench R15 single-core. The higher boost clock of 5.10 GHz versus 4.40 GHz partly explains this. Applications that depend on single-core speed, such as older games or lightly threaded productivity tools, will favor Intel.

For multithreaded rendering and compression, Intel's 14 cores provide a consistent 61.9 percent lead in Cinebench multicore tests and a 57.1 percent lead in data compression. The multithread PassMark score shows a 61.9 percent gap. Intel's higher TDP of 55 W versus 35 W supports sustained all-core workloads, though this also implies higher power consumption. AMD's lower TDP suggests better suitability for thermally constrained chassis, though the benchmark data does not include efficiency measurements.

AMD's only comparative strength lies in its thread count per core: 12 threads from 6 cores versus 14 threads from 14 cores. This means AMD's SMT implementation allows better utilization of each physical core, but the sheer core count advantage of Intel overrides that benefit in every measured workload.

The Verdict

The data shows the Intel Core Ultra 5 245HX is the superior processor in every measured benchmark. The average benchmark score of 48287 versus 19364 places Intel in the 90th percentile of all CPUs, while AMD sits in the 73rd percentile. The 17-to-0 win count in head-to-head tests leaves no ambiguity. Users who prioritize maximum performance across rendering, encryption, physics, compression, and single-threaded tasks should select the Intel part.

The AMD Ryzen 5 7533HS remains relevant only for scenarios where the 35 W TDP and smaller die size (208 mm² versus 243 mm²) are critical constraints. The database does not include power efficiency benchmarks, so the lower TDP cannot be quantified as a performance-per-watt advantage. However, the Intel part's 55 W TDP and larger die size indicate higher power draw and physical footprint. For systems where thermal budget is the limiting factor, AMD's lower TDP is the only measurable advantage. For all other criteria, the benchmark results point unequivocally to Intel.
