Architecture Differences

The two processors represent fundamentally different design approaches. The AMD Ryzen 7 PRO 5755G is built on the Zen 3 architecture with the Cezanne codename, fabricated on a 7 nm process at TSMC. It uses 8 cores and 16 threads, enabling simultaneous multithreading. The Intel Core Ultra 5 338H uses the Panther Lake architecture, fabricated on a 3 nm process at Intel, with 12 cores and 12 threads, meaning it does not support hyper-threading.

The AMD part is a desktop processor on the AMD Socket AM4 platform, while the Intel part is a mobile processor on the Intel BGA 2540 socket. The Ryzen 7 PRO 5755G has a 65 W TDP, while the Core Ultra 5 338H has a 25 W TDP, reflecting its mobile positioning.

Cache hierarchies differ substantially. The AMD processor provides 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of L3 cache. The Intel processor provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The larger per-core L2 on the Intel side is notable.

Memory support also diverges. The AMD chip uses DDR4 memory with dual-channel access and 51.2 GB/s of bandwidth. The Intel chip uses LPDDR5X memory, also dual-channel, but with 136.5 GB/s of bandwidth, more than double the AMD figure.

PCIe connectivity differs as well. The AMD Ryzen 7 PRO 5755G provides PCIe Gen 3 with 16 lanes from the CPU, while the Intel Core Ultra 5 338H provides PCIe Gen 5 with 4 lanes from the CPU.

Integrated graphics also separate the two. The AMD processor integrates Radeon Vega 8 graphics, while the Intel processor integrates Arc B370 graphics. Neither processor supports ECC memory, and neither has an unlocked multiplier.

The transistor count and die size for the AMD chip are recorded at 10,700 million transistors and 180 mm². No transistor count or die size is recorded for the Intel chip.

The Verdict

The data indicates the AMD Ryzen 7 PRO 5755G is the stronger overall processor in the database, with an average benchmark score of 49,196 versus 33,989 for the Intel Core Ultra 5 338H. This is a substantial gap of roughly 45% in favor of AMD. However, the AMD chip is a desktop part with a 65 W TDP, while the Intel chip is a mobile part with a 25 W TDP, so the comparison is between different market segments.

For users prioritizing raw multithreaded throughput and integer-heavy workloads, the AMD Ryzen 7 PRO 5755G delivers. Its 8 cores with 16 threads, combined with a 90th percentile ranking, place it alongside desktop processors like the AMD Ryzen 9 7900 and Intel Core i5-14600KF in average score.

For users prioritizing single-thread performance, floating-point math, physics simulations, and power efficiency, the Intel Core Ultra 5 338H is the better match. It wins 9 of 11 head-to-head tests, including a 19.5% advantage in single-thread score and a 39.6% advantage in floating-point math. Its 25 W TDP makes it suitable for mobile platforms where power is constrained.

The release dates also differ: the AMD processor was released in September 2024, while the Intel processor was released in January 2026. Both are marked as Active in production status.

Head-to-Head Benchmarks

The head-to-head results show a clear split between workload types. The AMD Ryzen 7 PRO 5755G wins two tests, both by significant margins. In data compression, it scores 295,730 versus 276,539 for Intel, a 6.9% advantage. In integer math, it scores 90,270 versus 64,934, a commanding 39% lead. These are the only two tests where AMD comes out ahead.

The Intel Core Ultra 5 338H wins the remaining nine tests. The largest Intel margin comes in the find prime numbers test, where it scores 304 versus 58 for AMD, an 80.9% advantage. Physics simulation shows a 62.1% lead for Intel, with scores of 2,697 versus 1,022. Floating-point math favors Intel by 39.6%, with scores of 84,067 versus 50,778.

The single-thread and singlethread tests both show Intel at 4,180 versus 3,366 for AMD, a 19.5% margin. Data encryption shows Intel at 21,367 versus 19,450, a 9% lead. Extended instructions favor Intel by 14.3%, with scores of 23,906 versus 20,487. Random string sorting shows a narrow 3.8% Intel advantage, with scores of 34,082 versus 32,771. Multithread performance favors Intel by 16.9%, with scores of 28,717 versus 23,858.

Despite Intel winning nine tests, the AMD processor still holds a higher average benchmark score overall. This reflects the magnitude of AMD's wins in compression and integer math, relative to the narrower margins in several Intel wins.

Where Each One Wins

The AMD Ryzen 7 PRO 5755G wins in data compression and integer math. These workloads indicate a strength in tasks that process large volumes of structured data, such as archiving, database operations, and general integer computation. The 39% advantage in integer math is the largest single margin for AMD in the head-to-head set.

The Intel Core Ultra 5 338H wins in single-thread performance, floating-point math, physics simulation, prime number finding, data encryption, extended instructions, random string sorting, and multithread. The 80.9% lead in prime number finding indicates a strong performance in workloads that rely on repeated simple arithmetic operations. The 62.1% lead in physics simulation points to a clear advantage in simulation and physical modeling tasks. The 39.6% lead in floating-point math covers scientific computing and graphics-related workloads.

The multithread result is notable. Despite having fewer threads (12 versus 16), the Intel processor scores 28,717 versus 23,858 in the PassMark multithread test, a 16.9% lead. This suggests that the Intel core design is more efficient per thread in this workload. However, the AMD processor's 16 threads still deliver a higher average benchmark score overall.

For mobile platforms where power consumption matters, the Intel Core Ultra 5 338H operates at 25 W TDP compared to 65 W for AMD, and its wins in single-thread and floating-point tests make it suitable for responsive, thermally constrained systems. The AMD Ryzen 7 PRO 5755G, with its desktop socket and higher TDP, fits stationary systems where the 8-core, 16-thread configuration and integer math advantage are prioritized.
