Architecture Differences

The foundational design choices for these two processors could not be more different. The AMD Ryzen 7 PRO 5755G is built on the Zen 3 architecture, codenamed Cezanne, and uses a 7 nm process node manufactured by TSMC. It is a desktop part designed for the AMD Socket AM4 platform. In contrast, the Intel Core Ultra 7 366H uses the Panther Lake architecture, is built on a 3 nm process node at Intel, and is a mobile processor designed for the Intel BGA 2540 socket.

The transistor count and die size data are only available for the AMD chip, which packs 10,700 million transistors into a 180 mm² die. The Intel part has no listing for these figures in the database. The cache hierarchies also differ substantially. The AMD processor provides 64 KB of L1 cache and 512 KB of L2 cache per core, with a 16 MB shared L3 cache. The Intel processor uses a much larger 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, with an 18 MB shared L3 cache.

Memory support is another distinguishing factor. The AMD Ryzen 7 PRO 5755G supports DDR4 memory in a dual-channel configuration, yielding a memory bandwidth of 51.2 GB/s. The Intel Core Ultra 7 366H supports DDR5 and LPDDR5X memory, also in a dual-channel configuration, but achieves a significantly higher memory bandwidth of 115.2 GB/s. PCIe connectivity also differs, with the AMD chip using Gen 3 with 16 lanes, while the Intel chip uses Gen 5 with 12 lanes.

Both processors integrate graphics, with the AMD featuring Radeon Vega 8 and the Intel featuring Xe3 Graphics. Neither processor supports ECC memory, and both have locked multipliers. The Intel chip has a notably lower TDP of 25 watts, compared to the AMD's 65 watts, which reflects its mobile focus and efficiency targets.

Head-to-Head Benchmarks

The head-to-head data reveals a dominant performance profile for the Intel Core Ultra 7 366H, but the AMD Ryzen 7 PRO 5755G is not without its strengths. The most decisive Intel victory comes in the find prime numbers test, where it scores 326 against the AMD's 58, an 82.2% advantage. This is followed by the physics test, where the Intel chip's 2880 score eclipses the AMD's 1022, a 64.5% lead. The floating point math test also shows a massive gap: the Intel chip scores 103615 versus 50778, a 51% difference.

The multithread test confirms the Intel chip's overall throughput advantage, with a score of 33429 compared to the AMD's 23858, a 28.6% difference. Data encryption and extended instructions also favor Intel by 24.7% and 23.8%, respectively. The data compression test shows a closer race, with Intel scoring 327455 against AMD's 295730, a 9.7% difference. Random string sorting and single-thread tests both favor Intel, with leads of 17.7% and 16.7%, respectively.

The single AMD victory is in the integer math test, where it scores 90270 against the Intel's 83695. This 7.9% win for the AMD chip is the only benchmark where it outpaces its rival, and it suggests that the Zen 3 architecture retains an edge in specific integer-heavy workloads. The data shows a clear pattern: Intel wins the majority of tests, often by large margins, but the AMD chip is not completely outclassed in every scenario.

The average benchmark scores from the database provide a broader context. The AMD Ryzen 7 PRO 5755G holds a higher average score of 49196, which places it in the 90th percentile. The Intel Core Ultra 7 366H, despite its many individual wins, has an average score of 41263 and sits in the 87th percentile. This discrepancy indicates that the AMD chip's performance is more consistent across a wider range of tests, even though it loses most of the specific comparisons in the head-to-head table.

The Verdict

The benchmark results indicate that the Intel Core Ultra 7 366H is the superior performer for most tasks, particularly those involving encryption, physics simulations, and prime number calculations. Its 16 cores, larger cache, and higher memory bandwidth deliver substantial wins in the majority of the recorded tests. The data shows a clear advantage for the Intel chip in multithreaded workloads, where its 33429 score is 28.6% higher than the AMD's 23858.

The AMD Ryzen 7 PRO 5755G, however, is not a weak processor. Its higher average benchmark score and 90th percentile ranking suggest that it excels in a broader set of applications than the head-to-head table captures. The AMD chip's 7.9% victory in integer math is a specific area of strength, and its lower TDP of 65 watts, while higher than the Intel's 25 watts, is reasonable for a desktop part.

For users who prioritize raw multi-core performance, encryption, and floating-point calculations, the Intel Core Ultra 7 366H is the clear choice based on the data. Its wins in physics (64.5% ahead) and floating point math (51% ahead) are decisive. For users who work with integer-heavy code or who value the higher overall average score, the AMD Ryzen 7 PRO 5755G may be the better option. The data does not support a single universal recommendation, but it does show that the Intel chip wins more head-to-head tests, while the AMD chip has a higher average score.

Specification Differences

The two processors differ in nearly every core specification field. The AMD Ryzen 7 PRO 5755G has 8 cores and 16 threads, while the Intel Core Ultra 7 366H has 16 cores and 16 threads. The base clock speeds are 3.80 GHz for the AMD and 2.00 GHz for the Intel, while the boost clocks are 4.60 GHz and 4.80 GHz, respectively. The TDPs are 65 watts for the AMD and 25 watts for the Intel.

The process nodes are 7 nm (TSMC) for the AMD and 3 nm (Intel) for the Intel. The cache configurations are distinct, with the AMD using 64 KB L1 and 512 KB L2 per core, and the Intel using 192 KB L1 and 2.5 MB L2 per core. The L3 caches are 16 MB for the AMD and 18 MB for the Intel. Memory support splits between DDR4 (AMD) and DDR5/LPDDR5X (Intel), with corresponding bandwidths of 51.2 GB/s and 115.2 GB/s. PCIe versions are Gen 3 with 16 lanes for the AMD and Gen 5 with 12 lanes for the Intel.

The integrated graphics are Radeon Vega 8 for the AMD and Intel Xe3 Graphics for the Intel. The sockets are AMD Socket AM4 and Intel BGA 2540. The release dates are September 2024 for the AMD and January 2026 for the Intel. Neither has a launch MSRP listed in the database.

Where Each One Wins

The Intel Core Ultra 7 366H wins in the vast majority of the recorded benchmarks. It leads in data compression, data encryption, extended instructions, find prime numbers, floating point math, multithread, physics, random string sorting, and both single-thread tests. This makes it the preferred processor for tasks that rely on high-throughput parallel processing, cryptographic workloads, and complex mathematical simulations. Its 16-core design and 18 MB L3 cache clearly benefit these applications.

The AMD Ryzen 7 PRO 5755G wins only in the integer math test, but this is a notable result. The 7.9% lead in integer math indicates that its Zen 3 architecture handles integer-heavy code efficiently. This could translate to advantages in specific database operations, compilers, or financial calculations that are integer-bound. Its higher average benchmark score of 49196 also suggests that it performs well across a wider range of tests than the head-to-head table alone suggests.

The data shows that the Intel chip is the better choice for users who need maximum performance in the tested workloads, especially given its wins in physics and floating point math. The AMD chip, with its higher percentile ranking and specific integer math strength, remains a viable option for workloads that align with its architectural strengths. The choice between the two depends entirely on the specific tasks being performed, as the benchmark data clearly delineates their respective areas of dominance.
