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

Head-to-Head Benchmarks

The recorded data shows a decisive sweep in favor of the Intel Core 9 273PQE across all 15 head-to-head tests. The AMD Ryzen AI 7 345 wins zero comparisons, while the Intel part wins every category. The margins are substantial, but the shape of the advantage differs across workloads.

In Cinebench R23, the Intel Core 9 273PQE scores 39,190 in multi-core versus 11,461 for the AMD, a delta of -70.8% for the AMD part relative to the Intel. The single-core R23 result is similarly lopsided: Intel scores 5,532 against AMD's 1,818, a -67.1% gap. Cinebench R15 shows the same pattern, with Intel at 3,950 multi-core versus AMD's 1,712 (-56.7%) and Intel at 557 single-core versus AMD's 271 (-51.3%). These are not close contests; the Intel part roughly doubles or triples the AMD output in every rendering test.

The PassMark suite reinforces this dominance. In integer math, Intel scores 164,629 versus AMD's 63,475, a -61.4% delta. Floating point math shows Intel at 125,546 versus AMD's 42,621 (-66.1%). Extended instructions favor Intel 38,743 to 17,003 (-56.1%). Data compression favors Intel 585,752 to 237,484 (-59.5%). Data encryption favors Intel 29,636 to 11,814 (-60.1%). Prime number finding favors Intel 198 to 62 (-68.7%). Random string sorting favors Intel 53,167 to 25,435 (-52.2%). PassMark multithread favors Intel 46,107 to 19,927 (-56.8%). PassMark physics favors Intel 2,754 to 1,089 (-60.5%).

The narrowest margin in the entire comparison is in PassMark single-thread performance. Intel scores 4,573, AMD scores 3,875, and the delta is -15.3%. That is still a clear Intel victory, but it is the only test where the AMD part stays within a close range. Every other test shows a gap of at least 50 percentage points. The data indicates that the Intel part's advantage grows with thread count and with more demanding instruction workloads, while single-thread performance is the AMD part's least severe deficit.

The Intel Core 9 273PQE's average benchmark score is 66,099, placing it at the 93rd percentile among all CPUs. The AMD Ryzen AI 7 345 averages 29,461, placing it at the 81st percentile. The Intel part's nearest rivals include the Intel Core Ultra 5 250KF Plus (average score 66,159, delta -0.1%), AMD Ryzen 9 7950X3D (65,914, delta 0.3%), Intel Core Ultra 5 250K Plus (66,855, delta -1.1%), and AMD EPYC 4465P (66,925, delta -1.2%). The AMD part's nearest rivals include the AMD Ryzen 7 3800X (29,447, delta 0%), AMD EPYC 9654 (29,409, delta 0.2%), Intel Core i5-13500HX (29,270, delta 0.7%), and AMD Ryzen 7 PRO 5755GE (29,656, delta -0.7%). These groupings confirm that the two processors occupy entirely different performance tiers.

Architecture Differences

The two processors are built on fundamentally different designs. The AMD Ryzen AI 7 345 uses the Krackan Point codename with a Zen 5 / Zen 5c generation, fabricated on a 4 nm TSMC process. The Intel Core 9 273PQE uses the Bartlett Lake codename with a Core 9 generation, fabricated on a 10 nm Intel process. The process node difference is significant: AMD's 4 nm versus Intel's 10 nm suggests a denser manufacturing approach for the AMD part.

Core counts differ sharply. The AMD part has 6 cores and 12 threads. The Intel part has 12 cores and 24 threads, exactly double in both categories. Base clocks also differ: AMD starts at 2.00 GHz, Intel at 3.40 GHz. Boost clocks differ as well: AMD reaches 4.60 GHz, Intel reaches 5.90 GHz. The Intel part's higher base and boost frequencies, combined with double the core count, explain the benchmark margins.

Cache hierarchies are distinct. Both parts have 80 KB of L1 per core. The L2 cache differs: AMD has 1 MB per core, Intel has 2 MB per core. The L3 cache shows the largest structural difference: AMD has 4 MB total, Intel has 36 MB shared. That 32 MB difference in last-level cache is substantial and directly relevant to workloads that repeatedly access large data sets.

Memory support differs. The AMD part supports DDR5 and LPDDR5X memory, dual-channel, with 89.6 GB/s bandwidth. The Intel part supports DDR4 and DDR5 memory, also dual-channel, also 89.6 GB/s. The Intel part supports ECC memory; the AMD part does not. PCIe lanes differ: AMD offers Gen 4 with 14 lanes (CPU only), Intel offers Gen 5 with 16 lanes (CPU only). Integrated graphics differ: AMD uses Radeon 840M, Intel uses UHD Graphics 770.

The sockets are not compatible. AMD uses Socket FP8, Intel uses Socket 1700. The AMD part is classified as a mobile processor, the Intel part as a desktop processor. The TDP ratings reflect this: AMD at 28 W, Intel at 125 W. The Intel part's power budget is more than four times higher, which aligns with its higher core count, clock speeds, and cache size.

The AMD part's release date is 2025-01-14, while the Intel part's release date is 2026-03-08. Both are listed as active in production. The Intel part has a launch MSRP of $589; the AMD part has no recorded launch MSRP.

The Verdict

The benchmark data points to a clear stratification. The Intel Core 9 273PQE is the superior performer in every measured category. Its average benchmark score is 66,099 versus 29,461 for the AMD, and it sits at the 93rd percentile versus the 81st. The Intel part wins 15 of 15 head-to-head tests, with margins ranging from -15.3% in single-thread to -70.8% in Cinebench R23 multi-core.

The AMD Ryzen AI 7 345 is not competitive with the Intel part in raw compute. The smallest gap, -15.3% in PassMark single-thread, is still a decisive Intel win. Every other gap is at least -51.3%. The data does not show a single workload category where the AMD part closes the distance.

The Intel part's advantage stems from its 12 cores, 24 threads, higher clocks, and much larger L3 cache. The AMD part's 6 cores, 12 threads, lower clocks, and 4 MB L3 cache place it in a different performance class. The TDP difference, 28 W versus 125 W, indicates that the AMD part is designed for constrained power envelopes while the Intel part is designed for maximum throughput.

For users choosing between these two, the decision rests on the performance tier required. The Intel part delivers roughly double the multi-threaded throughput and substantially higher single-thread performance. The AMD part offers a mobile form factor, lower power draw, and a 4 nm process, but the benchmark evidence shows it cannot match the Intel part in any compute test.

Where Each One Wins

The Intel Core 9 273PQE wins every benchmark category in the recorded data. Its largest margins come in multi-threaded rendering, where Cinebench R23 multi-core shows a -70.8% delta and Cinebench R15 multi-core shows -56.7%. Its smallest margin is in PassMark single-thread at -15.3%.

The AMD Ryzen AI 7 345 wins no benchmark categories. The data shows zero wins out of 15 head-to-head comparisons.

The use-case split, therefore, is not about which processor wins specific workloads. It is about which environments each processor suits. The AMD part is a mobile processor with a 28 W TDP, a 4 nm TSMC process, and LPDDR5X support. It is designed for power-constrained systems where the 6 cores and 12 threads are sufficient. The Intel part is a desktop processor with a 125 W TDP, a 10 nm Intel process, and DDR4 support in addition to DDR5. It is designed for systems that can supply ample power and cooling in exchange for double the cores, double the threads, and a substantially larger cache.

The benchmark data confirms that the Intel part is the choice for compute-heavy workloads. The AMD part is the choice for mobile systems where the 28 W TDP and 4 nm process are the primary constraints.
