AMD Ryzen 9 270 vs Intel Core i9-13905H Comparison

The Intel Core i9-13905H and AMD Ryzen 9 270 are two mobile processors that land within 0.2% of each other by average benchmark score, but they achieve that parity through completely different means. The Intel part, a 14-core Raptor Lake-H chip, leans on its hybrid core layout, while the AMD Ryzen 9 270, a Zen 4 Hawk Point part, counters with higher clock speeds and a more efficient architecture. The data shows a near-total split: Intel wins on raw multi-threaded throughput in several classic tests, while AMD dominates in single-core and modern rendering workloads, making the choice heavily dependent on the specific application.

Head-to-Head Benchmarks

The most decisive win for the Intel Core i9-13905H comes in `passmark_physics`, where it scores 2054 against AMD's 1365, a 50.5% advantage. This is the largest delta in the entire comparison and suggests that Intel's hybrid architecture, with its 14 cores and 20 threads, handles the physics simulation workload far better than the Ryzen's 8 cores and 16 threads. Similarly, in `passmark_find_prime_numbers`, Intel scores 122 versus AMD's 88, a 38.6% lead, indicating a substantial edge in integer-heavy, latency-sensitive tasks. Intel also wins `passmark_floating_point_math` with 73434 against 60122, a 22.1% gap, and `passmark_integer_math` by a smaller 3.5% margin (101716 vs 98266). The Intel chip also takes `passmark_multithread` (29779 vs 29089, +2.4%) and `cinebench_cinebench_r15_multicore` (2857 vs 2664, +7.2%), showing that in certain legacy workloads, the extra cores and threads pay off.

However, the AMD Ryzen 9 270 strikes back with overwhelming force in the more modern Cinebench suite. In `cinebench_cinebench_r23_singlecore`, AMD scores 3732 against Intel's 2020, a staggering 45.9% lead. This is not a small margin; it is a generational gap in single-threaded performance. The same pattern holds in `cinebench_cinebench_r23_multicore`, where AMD scores 26438 versus Intel's 20034, a 24.2% advantage. This is particularly notable because it shows that despite having fewer cores, the AMD chip's higher clock speeds (base 4.00 GHz vs 2.60 GHz) and better IPC allow it to outpace the Intel chip in a modern multi-threaded render. AMD also wins `cinebench_cinebench_r20_multicore` (11103 vs 10605, +4.5%) and `cinebench_cinebench_r20_singlecore` (1567 vs 1497, +4.5%). In `cinebench_cinebench_r15_singlecore`, AMD's lead is 376 vs 246, a 34.6% delta.

The remaining tests are closer. AMD wins `passmark_single_thread` (3784 vs 3703, +2.1%) and `passmark_data_encryption` (20852 vs 20464, +1.9%). Intel wins `passmark_data_compression` by a hair (354330 vs 351398, +0.8%). AMD takes `passmark_extended_instructions` convincingly (26729 vs 21297, +20.3%) and `passmark_random_string_sorting` (42819 vs 37460, +12.5%). The final tally is 10 wins for AMD and 7 for Intel, but the magnitude of AMD's wins in the Cinebench and single-core tests dwarfs Intel's victories in the physics and prime number tests.

Where Each One Wins

The Intel Core i9-13905H is the clear winner for workloads that depend on legacy multi-threaded performance or specific math operations. If you are running physics simulations, the data shows a 50.5% advantage over the Ryzen 9 270. For prime number calculations, which are often used in cryptography and certain scientific computing tasks, Intel leads by 38.6%. Floating-point math is another stronghold, with a 22.1% lead. The Intel chip also holds a slight edge in integer math (3.5%) and general multithreaded tasks (2.4%). For users running older Cinebench R15 multi-core benchmarks, the Intel chip is 7.2% faster. This makes the Intel part a better choice for specific legacy scientific or engineering software that relies on these older instruction paths.

The AMD Ryzen 9 270 is the dominant performer in almost everything that matters for modern productivity and content creation. The 45.9% lead in Cinebench R23 single-core is the headline figure, but the 24.2% lead in R23 multi-core is arguably more important, as it shows that the AMD chip can out-render the Intel chip even in a fully threaded workload. The 20.3% lead in extended instructions (`passmark_extended_instructions`) suggests that AMD is better at handling modern SIMD workloads like AVX-512 or similar. AMD also wins on random string sorting (12.5%), which is relevant for data processing and database operations. For any user running current versions of Blender, HandBrake, or Adobe Premiere, the Ryzen 9 270 is the superior processor based on this data.

Architecture Differences

The Intel Core i9-13905H is built on Raptor Lake-H, using a 10 nm process at Intel's foundry. It packs 14 cores (likely a mix of performance and efficiency cores) and 20 threads, with a massive 24 MB of shared L3 cache. The L1 cache is 80 KB per core, and L2 is 2 MB per core. It supports both DDR4 and DDR5 memory in a dual-channel configuration, and its integrated graphics are Iris Xe Graphics with 96 execution units. The chip uses the Intel BGA 1744 socket, has a base clock of 2.60 GHz, and boosts up to 5.40 GHz. The die size is a large 257 mm².

The AMD Ryzen 9 270 is built on Zen 4, using a 4 nm process at TSMC. It has 8 cores and 16 threads, with a smaller 16 MB of shared L3 cache. The L1 cache is 64 KB per core, and L2 is 1 MB per core. It only supports DDR5 memory (dual-channel), and its memory bandwidth is specified at 89.6 GB/s. The integrated graphics are Radeon 780M. It uses the AMD Socket FP8, has a base clock of 4.00 GHz, and boosts to 5.20 GHz. The die size is 178 mm², and the chip contains 25,000 million transistors. The AMD chip also has more PCIe lanes (20 lanes of Gen 4) versus Intel's 8 lanes of Gen 5 (CPU only).

The core count difference is the most obvious architectural split: Intel has 14 cores vs AMD's 8. However, the AMD chip's higher base clock (4.00 GHz vs 2.60 GHz) and its 4 nm process (vs 10 nm) give it a significant efficiency and IPC advantage. The larger L3 cache on the Intel chip (24 MB vs 16 MB) does not compensate for the IPC gap in most tests.

The Verdict

The data is clear: for modern workloads, the AMD Ryzen 9 270 is the superior processor. Its 45.9% lead in single-core R23 and 24.2% lead in multi-core R23 are decisive. If you are building a mobile workstation for rendering, compiling, or video editing, the AMD chip is the one to get. The only reason to choose the Intel Core i9-13905H is if your specific software relies on the older Cinebench R15 multi-core path (7.2% faster) or the `passmark_physics` workload (50.5% faster). The Intel chip also wins on `passmark_find_prime_numbers` and `floating_point_math`, but these are niche scientific workloads. For general use, the AMD chip's wins in single-thread, extended instructions, and random string sorting make it the more versatile and future-proof choice. Both chips are in the 87th percentile of all CPUs, but the AMD chip achieves that status with fewer cores and a smaller die, indicating better efficiency.
