AMD Ryzen AI 9 365 vs Intel Core 9 273PE Comparison

Head-to-Head Benchmarks

The benchmark data records 15 head-to-head comparisons between the AMD Ryzen AI 9 365 and the Intel Core 9 273PE. The Intel part wins 12 of those matchups, while the AMD chip takes 3. The margin of victory varies widely by workload, from a near-tie in extended instructions to a crushing 54.9% deficit for AMD in Cinebench R23 single-core.

The single largest gap appears in Cinebench R23 single-core, where Intel scores 4417 against AMD's 1992. That is a 54.9% difference, and it sets the tone for most single-threaded work. Cinebench R15 single-core tells a similar story: Intel at 445, AMD at 303, a 31.9% lead for Intel. These are not small margins; they indicate a fundamental per-thread performance advantage for the Intel design.

Multi-threaded rendering also favors Intel heavily. In Cinebench R23 multi-core, Intel posts 31288 versus AMD's 18698, a 40.2% advantage. Cinebench R15 multi-core shows Intel at 3153 against AMD's 2842, a narrower 9.9% lead. The R23 result is particularly striking because it suggests that the Intel chip scales better with additional threads, not just faster individual cores.

The PassMark suite reveals a mixed picture. Intel wins data compression (405885 vs 354510, a 12.7% lead), data encryption (22719 vs 18297, a 19.5% lead), find prime numbers (203 vs 117, a 42.4% lead), floating point math (107884 vs 62802, a 41.8% lead), integer math (139410 vs 101831, a 27% lead), multithread (36810 vs 29467, a 19.9% lead), physics (3120 vs 1704, a 45.4% lead), and random string sorting (45098 vs 39447, a 12.5% lead).

AMD wins two PassMark single-thread tests (both recorded as 3841 versus Intel's 3650, a 5.2% advantage) and the extended instructions test (25113 vs 24630, a 2% lead). The extended instructions margin is small, but it shows AMD's x86 instruction handling is competitive. The single-thread PassMark result is curious, because Intel dominates Cinebench single-core tests. The discrepancy likely reflects different workload characteristics: PassMark single-thread may exercise memory latency or branch prediction patterns differently than Cinebench's rendering workload.

Overall, the data shows Intel winning by double digits in most compute-heavy tasks, while AMD's wins are narrow (2% and 5.2%) and concentrated in specific instruction-level and single-threaded PassMark scenarios.

Where Each One Wins

The Intel Core 9 273PE is the clear choice for rendering, physics simulation, encryption, compression, and prime number finding. Its Cinebench R23 multi-core score of 31288 is 40.2% above AMD's 18698, which directly translates to faster video exports, 3D scene renders, and other parallel CPU workloads. The physics test (3120 vs 1704, a 45.4% lead) indicates stronger performance in game physics or simulation code that uses floating point heavily.

The AMD Ryzen AI 9 365 wins in extended instructions (25113 vs 24630) and in the PassMark single-thread test (3841 vs 3650). The extended instructions result suggests AMD's Zen 5 core executes SIMD or specialized instruction sequences slightly faster. The single-thread PassMark win is narrow, but it indicates that for certain lightweight, latency-sensitive tasks, the AMD chip can edge ahead despite its lower clock speeds.

For integer math and floating point math, Intel dominates with 27% and 41.8% leads respectively. These are broad workload categories that cover most general-purpose computing, so Intel's advantage here matters for everyday productivity, spreadsheet calculations, and scientific computing. Data compression (12.7% lead) and random string sorting (12.5% lead) show Intel also handles memory-bound and I/O-like tasks faster.

The takeaway: Intel wins the heavy lifting, AMD wins a few narrow skirmishes. If the workload is rendering or math-heavy simulation, the data points firmly to Intel. If the workload involves specialized instruction sequences or specific single-threaded patterns, AMD holds its own.

Architecture Differences

The AMD Ryzen AI 9 365 uses Zen 5 architecture on a 4 nm TSMC process, codenamed Strix Point. The Intel Core 9 273PE uses Bartlett Lake on a 10 nm Intel process. The process node difference is significant: 4 nm versus 10 nm suggests AMD has a transistor density advantage, yet Intel still achieves higher clock speeds and better benchmark results.

AMD's chip has 10 cores and 20 threads. Intel's has 12 cores and 24 threads. That 2-core, 4-thread difference partially explains Intel's multi-threaded lead, but not entirely. Intel's Cinebench R23 multi-core score is 40.2% higher, while its core count is only 20% higher. The per-core efficiency also favors Intel in this comparison.

Cache configurations differ substantially. Both have 80 KB L1 per core, but AMD uses 1 MB L2 per core versus Intel's 2 MB L2 per core. AMD has 16 MB L3 total, while Intel has 36 MB L3 shared. Intel's larger L3 cache likely contributes to its strong performance in data compression and random string sorting, which benefit from larger working sets staying in cache.

AMD is a mobile part, using Socket FP8, while Intel is a desktop part, using Socket 1700. That market segment difference explains some of the performance gap: the Intel chip has a 65 W TDP versus AMD's 28 W TDP. The higher power envelope allows Intel to sustain higher clock speeds, and the data shows boost clocks of 5.70 GHz versus 5.00 GHz.

Memory support differs. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both have dual-channel memory buses and identical 89.6 GB/s bandwidth figures. Intel adds ECC memory support, which AMD lacks. PCIe also differs: Intel provides Gen 5 with 16 lanes, AMD provides Gen 4 with 16 lanes. That makes Intel more suitable for high-bandwidth expansion cards and storage.

Integrated graphics differ as well. AMD uses the Radeon 880M, Intel uses UHD Graphics 730. The database does not record graphics benchmark scores, so no performance comparison is possible from the available data.

The Verdict

The benchmark data records a clear overall winner: the Intel Core 9 273PE. It wins 12 of 15 head-to-head tests, often by large margins. Its Cinebench R23 multi-core score (31288) and single-core score (4417) are both far ahead of the AMD Ryzen AI 9 365 (18698 and 1992 respectively). For any workload dominated by rendering, physics, encryption, or general math, the Intel part delivers substantially higher performance.

The AMD Ryzen AI 9 365 has a 28 W TDP versus Intel's 65 W TDP, which makes it suitable for power-constrained mobile systems. It also carries a 4 nm process node versus Intel's 10 nm, and its integrated Radeon 880M may offer different graphics capabilities than Intel's UHD Graphics 730, though the database does not record graphics benchmarks. AMD's wins in extended instructions and PassMark single-thread show that its Zen 5 core is not without merit in specific scenarios.

The Intel Core 9 273PE carries a launch MSRP of $549. The AMD chip has no listed launch MSRP. The Intel part also supports ECC memory and PCIe Gen 5, making it the more feature-complete desktop processor.

For a desktop build where performance is the priority, the recorded data points directly to the Intel Core 9 273PE. For a mobile system where power consumption matters more than raw throughput, the AMD Ryzen AI 9 365 is the only viable option of the two, given its mobile socket and lower TDP. The choice depends on the use case: Intel for maximum compute, AMD for mobility and efficiency.
