AMD Ryzen 7 PRO 5755G vs Intel Core Ultra 5 245HX Comparison

The AMD Ryzen 7 PRO 5755G and the Intel Core Ultra 5 245HX represent two distinct philosophies in processor design, yet both land in the 90th percentile of all CPUs tracked. The Intel part, a 14-core Arrow Lake-HX mobile chip, dominates the shared PassMark benchmark suite in this comparison, while the AMD Cezanne desktop processor holds its ground in a few narrow workloads. The data shows a decisive overall performance advantage for the Intel part across the majority of tested scenarios, with the margin varying dramatically depending on the specific workload.

Head-to-Head Benchmarks

The Intel Core Ultra 5 245HX wins all eleven shared benchmark comparisons, but the magnitude of those victories is far from uniform. The largest single gap appears in `passmark_find_prime_numbers`, where Intel scores 359 against AMD’s 58, a delta of -83.8% from the AMD perspective. This indicates an extreme advantage for the Intel architecture in this specific integer-heavy workload, suggesting a significantly more efficient processing path for this type of calculation. Similarly, the `passmark_physics` test shows Intel at 2526 versus AMD’s 1022, a -59.5% difference, and `passmark_floating_point_math` shows Intel at 120735 versus 50778, a -57.9% gap. These are not minor margins; they represent Intel finishing more than double the AMD score in floating-point operations.

The gap narrows considerably in other areas. In `passmark_integer_math`, the Intel score of 92150 is only 2% ahead of AMD’s 90270. This is the closest contest in the entire suite, indicating that the AMD Ryzen 7 PRO 5755G is highly competitive in basic integer arithmetic, a fundamental building block for many general-purpose tasks. The `passmark_data_compression` test also shows a substantial but less extreme Intel lead, with a score of 393071 against AMD’s 295730, a -24.8% delta. For `passmark_data_encryption`, Intel leads with 30022 versus 19450, a -35.2% gap. The `passmark_extended_instructions` workload shows a -34.4% delta in Intel’s favor, with scores of 31212 and 20487 respectively.

The overall multithreaded picture is clear. In `passmark_multithread`, Intel scores 38069 against AMD’s 23858, a -37.3% difference. This mirrors the single-thread results, where Intel’s score of 4481 is -24.9% higher than AMD’s 3366. The `passmark_random_string_sorting` test shows Intel ahead with 47616 versus 32771, a -31.2% delta. While the Intel part wins every contest, the average benchmark score tells a slightly different story: Intel’s average of 48287 is lower than AMD’s 49196. This is because the Intel benchmark list includes several Cinebench scores, which drag down its average, whereas the AMD list consists solely of PassMark scores. The head-to-head data, however, is unambiguous in its verdict: Intel holds the performance crown in every shared test.

Where Each One Wins

Given the head-to-head results, the Intel Core Ultra 5 245HX is the clear winner in any workload that involves heavy parallel processing, floating-point mathematics, physics simulation, or data encryption. The benchmark results indicate that the Intel part is particularly well-suited for tasks like scientific computing, financial modeling, and content creation, where its 120735 `passmark_floating_point_math` score and 2526 `passmark_physics` score would provide a substantial advantage. The 4471-point lead in `passmark_single_thread` also suggests a smoother experience in lightly-threaded applications like web browsing and office productivity, though the AMD part is by no means sluggish.

The AMD Ryzen 7 PRO 5755G’s only real area of competitive strength is in `passmark_integer_math`, where its 90270 score trails Intel’s 92150 by only 2%. This suggests that for basic integer-centric operations, the two processors are nearly equivalent. The AMD part also holds a higher average benchmark score (49196) compared to Intel (48287), which means that across the full breadth of benchmarks for each CPU, the AMD part performs better on average, even if it loses every direct head-to-head test. This is a statistical quirk of the benchmark lists, but it does indicate that the AMD part is not a slouch in general-purpose computing. For users whose primary workload is integer-based data processing or who rely on the AMD platform’s desktop socket, the 5755G remains a viable option, but for raw performance across the board, the Intel part is the one to choose.

Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 7 PRO 5755G uses the Zen 3 architecture with the Cezanne codename, fabricated on a 7 nm process at TSMC. It is a monolithic design with 10,700 million transistors on a 180 mm² die. In contrast, the Intel Core Ultra 5 245HX is based on the Arrow Lake architecture with the Arrow Lake-HX codename, fabricated on a 3 nm process, also at TSMC. It uses more transistors (17,800 million) and a larger die size (243 mm²). This newer, denser process node is a major factor in the Intel part’s performance advantage, allowing for more transistors and higher efficiency.

The core configuration differs significantly. The AMD part has 8 cores and 16 threads, while the Intel part has 14 cores and 14 threads. This means the Intel part has more physical cores but no hyperthreading, whereas the AMD part relies on simultaneous multithreading to reach 16 threads from 8 cores. The cache hierarchy is also distinct. The AMD part features 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. The Intel part has a much larger 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. The larger per-core caches on the Intel part are likely a key contributor to its strong single-threaded performance.

The memory and I/O interfaces also diverge. The AMD part supports DDR4 memory with dual-channel configuration, providing 51.2 GB/s of bandwidth. The Intel part supports DDR5 memory, also dual-channel, but with a much higher 102.4 GB/s bandwidth. The PCIe interface differs as well: the AMD part provides Gen 3 with 16 lanes, while the Intel part provides Gen 5 with 20 lanes. The integrated graphics are different too: AMD uses the Radeon Vega 8, while Intel uses the Arc Xe-LPG Graphics 48EU. These architectural differences explain the performance deltas, with the Intel part’s newer node, larger caches, and faster memory all contributing to its superior benchmark results.

Specification Differences

The most obvious difference is the core and thread count: the AMD Ryzen 7 PRO 5755G offers 8 cores and 16 threads, while the Intel Core Ultra 5 245HX offers 14 cores and 14 threads. Clock speeds also differ, with the AMD part having a base clock of 3.80 GHz and a boost of 4.60 GHz, while the Intel part has a lower base of 3.10 GHz but a higher boost of 5.10 GHz. The TDP is lower on the Intel part at 55 watts versus 65 watts for the AMD part.

The socket and market segment are fundamentally different. The AMD part uses the AMD Socket AM4 and is a desktop processor, while the Intel part uses Intel BGA 2114 and is a mobile processor. The process node differs, with AMD on 7 nm and Intel on 3 nm, leading to different transistor counts (10,700 million vs 17,800 million) and die sizes (180 mm² vs 243 mm²). The cache configuration is also distinct, with AMD offering 64 KB L1 and 512 KB L2 per core, and Intel offering 192 KB L1 and 3 MB L2 per core; the L3 cache is 16 MB shared on AMD versus 24 MB shared on Intel.

Memory support is a major divergence: AMD supports DDR4 with 51.2 GB/s bandwidth, while Intel supports DDR5 with 102.4 GB/s bandwidth. The PCIe versions also differ, with AMD on Gen 3 (16 lanes) and Intel on Gen 5 (20 lanes). The integrated graphics are different, with AMD’s Radeon Vega 8 versus Intel’s Arc Xe-LPG Graphics 48EU. The multiplier is locked on the AMD part and unlocked on the Intel part. Intel’s part number is SRVFM, while AMD’s is 100-000001748. The release dates also differ, with AMD released in September 2024 and Intel in January 2025.
