Both support ECC memory and use dual-channel buses with 89.6 GB/s bandwidth. The process node difference is notable: 4 nm for AMD versus 10 nm for Intel. The AMD part is explicitly a mobile segment product, while the Intel part is a desktop segment product, which aligns with the TDP difference of 28 W versus 45 W.

Head-to-Head Benchmarks

The recorded data shows 15 head-to-head comparisons, with the AMD Ryzen AI 7 450 winning 9 and the Intel Core 9 273PTE winning 6.

The AMD processor's largest victory comes in PassMark extended instructions, where it scores 22400 against 15952, a 40.4% margin. This is followed by a 31.7% win in Cinebench R15 multi-core (2713 vs 2060). The AMD chip also shows strong results in PassMark random string sorting, winning by 23% (35648 vs 28973), and in data compression with a 22.1% lead (315906 vs 258704). In data encryption, AMD leads by 14% (16247 vs 14253). The PassMark multithread test shows AMD ahead by 9.5% (26350 vs 24054). Integer math goes to AMD by 7.4% (88531 vs 82411). The PassMark single-thread test shows AMD ahead by 13.6% (3901 vs 3433), with the same result recorded for the singlethread variant.

The Intel Core 9 273PTE's biggest win is in Cinebench R23 single-core, where it scores 2886 versus 2038, a 29.4% margin. It also wins Cinebench R15 single-core by 25.9% (290 vs 215). PassMark physics shows Intel ahead by 17.7% (1917 vs 1578). In PassMark find prime numbers, Intel wins by 37.3% (142 vs 89). Floating point math goes to Intel by 10.3% (60673 vs 54447). Finally, Cinebench R23 multi-core goes to Intel by 10.4% (20445 vs 18316).

The pattern is clear: AMD wins most PassMark workloads, especially those involving compression, encryption, extended instructions, and multithreaded integer work. Intel wins in Cinebench single-core tests decisively and takes the newer Cinebench R23 multi-core test, along with prime number finding, physics, and floating point math.

Where Each One Wins

The AMD Ryzen AI 7 450 demonstrates strength across a broad set of data-processing workloads. Data compression and encryption show clear AMD advantages, with 22.1% and 14% margins respectively. Extended instruction execution is where AMD shines brightest, with a 40.4% lead. Random string sorting, which typically exercises memory access patterns and branch handling, favors AMD by 23%. Integer math and multithreaded performance both go to AMD, with margins of 7.4% and 9.5%. The PassMark single-thread result also favors AMD, which is notable given that Intel wins both Cinebench single-core tests.

The Intel Core 9 273PTE wins in classic rendering workloads and specific compute patterns. Cinebench R23 multi-core, often used for CPU rendering performance, goes to Intel by 10.4%. Both Cinebench single-core tests favor Intel substantially, with margins of 25.9% and 29.4%. Physics simulation, which often relies on floating point throughput, favors Intel by 17.7%. The find prime numbers test, a pure integer workload, goes to Intel by 37.3%, and floating point math favors Intel by 10.3%.

This split suggests that the AMD processor handles a wider variety of everyday compute tasks efficiently, while the Intel processor excels in rendering workloads and specific mathematical operations. The Cinebench R23 multi-core result is particularly interesting because it contradicts the older R15 multi-core result, indicating that the newer rendering test favors Intel's architecture differently.

The Verdict

The data indicates a processor choice that depends heavily on workload priorities. The AMD Ryzen AI 7 450 wins 9 of 15 head-to-head benchmarks and holds a higher average benchmark score of 39485 versus 31143 for Intel. It also sits higher in the percentile ranking at 87 versus 82. For users focused on data compression, encryption, extended instruction sets, integer math, and general multithreaded throughput, the AMD part is the clear choice based on the recorded results.

The Intel Core 9 273PTE wins 6 of 15 comparisons and excels in rendering workloads, particularly Cinebench R23 multi-core and both Cinebench single-core tests. It also wins physics simulation, prime number finding, and floating point math. For workloads that rely on these specific patterns, the Intel part delivers meaningfully higher scores, with margins ranging from 10.3% to 37.3%. The Intel processor also offers 12 cores and 24 threads versus 8 cores and 16 threads, along with a larger 36 MB L3 cache and PCIe Gen 5 support.

The AMD chip operates at a much lower 28 W TDP versus 45 W for Intel, and it uses a more advanced 4 nm process node from TSMC. The Intel part carries a launch MSRP of $549. The AMD processor is designed for mobile platforms, while the Intel processor targets desktop systems. The recorded data does not indicate a universal winner; it shows two processors optimized for different segments and workload types. The higher average score and more benchmark wins belong to AMD, but the rendering and specific compute advantages of Intel cannot be ignored for those specific tasks.
