AMD Ryzen AI 7 345 vs Intel Core 9 273PTE Comparison

The AMD Ryzen AI 7 345 and Intel Core 9 273PTE are different classes of processors: the AMD part is a 6-core mobile chip on AMD Socket FP8, while the Intel part is a 12-core desktop chip on Intel Socket 1700. Recorded head-to-head benchmarks show Intel winning 12 of 15 comparisons and AMD winning 3. The AMD part posts an average benchmark score of 29461 and ranks at the 81st percentile, while the Intel part averages 31143 and ranks at the 82nd percentile.

Where Each One Wins

The Intel Core 9 273PTE wins every Cinebench comparison. It scores 2060 in Cinebench R15 multicore against 1712, 290 in R15 singlecore against 271, 20445 in R23 multicore against 11461, and 2886 in R23 singlecore against 1818. Intel also wins PassMark data compression, data encryption, find prime numbers, floating point math, integer math, multithread, physics, and random string sorting.

The AMD Ryzen AI 7 345 wins the remaining PassMark workloads: extended instructions with 17003 against 15952, and the PassMark single-thread metric with 3875 against 3433. That split is clean. Intel owns multi-threaded throughput, math-heavy workloads, physics simulation, compression, and encryption. AMD owns a narrower set of strengths in extended instruction throughput and single-thread PassMark performance.

Architecture Differences

The two processors use different nodes, different sockets, and different core configurations. AMD uses a 4 nm TSMC process, while Intel uses a 10 nm Intel process. AMD’s Krackan Point belongs to the Ryzen AI 300 generation with Zen 5 / Zen 5c cores. Intel’s Bartlett Lake is the Core 9 generation.

The AMD part has 6 cores and 12 threads with a 2.00 GHz base clock and a 4.60 GHz boost clock. The Intel part has 12 cores and 24 threads with a 1.40 GHz base clock and a 5.50 GHz boost clock. TDP is 28 for AMD and 45 for Intel. AMD uses AMD Socket FP8, while Intel uses Intel Socket 1700.

Cache configurations differ substantially. Both use 80 KB L1 per core, but AMD has 1 MB L2 per core and 4 MB L3, while Intel has 2 MB L2 per core and 36 MB shared L3. Memory support also differs: AMD supports DDR5 and LPDDR5X, Intel supports DDR4 and DDR5. Both run dual-channel memory with 89.6 GB/s bandwidth. ECC memory is supported on Intel but not on AMD.

PCIe connectivity is different as well. AMD provides Gen 4 with 14 CPU lanes, and Intel provides Gen 5 with 16 CPU lanes. The integrated graphics are Radeon 840M on AMD and UHD Graphics 730 on Intel. AMD is a mobile processor, Intel is a desktop processor. AMD was released on 2025-01-14, Intel on 2026-03-08. Both have locked multipliers.

Head-to-Head Benchmarks

The table below records the full set of head-to-head comparisons from the database. Delta is calculated from the AMD score relative to the Intel score, so negative values favor Intel and positive values favor AMD.

| Benchmark | AMD Ryzen AI 7 345 | Intel Core 9 273PTE | Delta |

|---|---|---|---|

| Cinebench R15 multicore | 1712 | 2060 | -16.9% |

| Cinebench R15 singlecore | 271 | 290 | -6.6% |

| Cinebench R23 multicore | 11461 | 20445 | -43.9% |

| Cinebench R23 singlecore | 1818 | 2886 | -37.0% |

| PassMark data compression | 237484 | 258704 | -8.2% |

| PassMark data encryption | 11814 | 14253 | -17.1% |

| PassMark extended instructions | 17003 | 15952 | +6.6% |

| PassMark find prime numbers | 62 | 142 | -56.3% |

| PassMark floating point math | 42621 | 60673 | -29.8% |

| PassMark integer math | 63475 | 82411 | -23.0% |

| PassMark multithread | 19927 | 24054 | -17.2% |

| PassMark physics | 1089 | 1917 | -43.2% |

| PassMark random string sorting | 25435 | 28973 | -12.2% |

| PassMark single thread | 3875 | 3433 | +12.9% |

| PassMark singlethread | 3875 | 3433 | +12.9% |

The largest Intel margin is in PassMark find prime numbers, where Intel scores 142 against 62, a 56.3% gap. Cinebench R23 multicore follows with a 43.9% gap, and PassMark physics trails at 43.2%. Intel also leads Cinebench R23 singlecore by 37.0% and floating point math by 29.8%. The AMD wins are smaller in percentage: 12.9% on PassMark single-thread and 6.6% on extended instructions.

The two PassMark single-thread rows are the same test recorded twice, so the effective workload split remains 12 Intel wins and 3 AMD wins. Intel’s advantage is broad across rendering, physics, integer math, encryption, compression, and sorting.

The Verdict

The recorded data favors the Intel Core 9 273PTE for workloads where multi-core throughput is the priority. It wins 12 of 15 head-to-head tests, including every Cinebench test, and its average benchmark score of 31143 is higher than AMD’s 29461. Its percentile ranking of 82 is one point above AMD’s 81.

The nearest rival data reinforces the class positioning. The AMD part sits near the AMD Ryzen 7 3800X at 29447 with a delta of 0%, the AMD EPYC 9654 at 29409 with a delta of 0.2%, and the Intel Core i5-13500HX at 29270 with a delta of 0.7%. The Intel part sits near the Intel Core i7-12700F at 31081 with a delta of 0.2%, the AMD Ryzen 9 8945HS at 31074 with a delta of 0.2%, and the Intel Core i7-13700TE at 31028 with a delta of 0.4%.

The AMD Ryzen AI 7 345 is the data-backed choice for workloads dominated by PassMark single-thread performance or extended instruction throughput, and for systems where a mobile platform with a 28 TDP is required. It also brings the Radeon 840M integrated graphics and an earlier release date. It does not match Intel in multi-core Cinebench, physics, integer math, encryption, or compression.
