AMD Ryzen AI 9 HX PRO 375 vs Intel Core 9 273PTE Comparison

The AMD Ryzen AI 9 HX PRO 375 and Intel Core 9 273PTE are both 12-core, 24-thread processors, but they target entirely different segments of the market. The AMD chip is a mobile part built for the FP8 socket, while the Intel chip is a desktop processor on Socket 1700. The AMD processor uses the Zen 5 architecture on a 4 nm TSMC process, whereas the Intel part is based on the Bartlett Lake design on Intel's 10 nm node. Both parts support ECC memory and dual-channel memory with identical 89.6 GB/s bandwidth, but the AMD chip only supports DDR5 and LPDDR5X, while the Intel chip also adds DDR4 support. The AMD chip has a lower 28 W TDP and a base clock of 2.00 GHz, while the Intel chip draws 45 W with a 1.40 GHz base clock. The AMD chip boosts to 5.10 GHz, while the Intel chip reaches 5.50 GHz. The AMD part integrates Radeon 890M graphics, while the Intel part has UHD Graphics 730.

Architecture Differences

The two processors diverge sharply in their underlying designs. The AMD Ryzen AI 9 HX PRO 375 is built around the Zen 5 architecture, using the Strix Point codename. It is manufactured on a 4 nm process at TSMC and has a die size of 233 mm². The Intel Core 9 273PTE uses the Bartlett Lake codename, representing the Core 9 generation, and is fabricated on Intel's 10 nm process. The AMD chip is a mobile processor, while the Intel chip is a desktop part, which explains the difference in socket types: AMD Socket FP8 versus Intel Socket 1700.

Cache layouts differ significantly. Both CPUs have 80 KB of L1 cache per core and 1 MB of L2 cache per core on the AMD side, but the Intel chip doubles the L2 to 2 MB per core. The L3 cache is a major divergence point: the AMD processor has 16 MB of L3, while the Intel processor has 36 MB shared L3, more than double the AMD capacity. The AMD chip does not list a 3D V-Cache option, and neither does the Intel part.

PCIe support separates the two as well. The AMD chip provides Gen 4 with 16 lanes (CPU only), while the Intel chip provides Gen 5 with 16 lanes (CPU only). This gives the Intel desktop part a generational advantage in raw I/O bandwidth, though the AMD part's mobile positioning means it is often paired with integrated peripherals. The AMD chip has a 28 W TDP, making it a lower-power mobile solution, while the Intel chip's 45 W TDP is more typical of a desktop processor with higher sustained power delivery. Both parts are locked (multiplier not unlocked) and are listed as Active in production status.

Head-to-Head Benchmarks

The benchmark data shows a dominant performance profile for the AMD Ryzen AI 9 HX PRO 375 across most tested workloads, but the Intel Core 9 273PTE does secure two specific wins. Of the 17 head-to-head benchmark comparisons, the AMD chip wins 15, and the Intel chip wins 2.

In Cinebench tests, the AMD processor consistently leads by a wide margin. In Cinebench R15 multicore, the AMD chip scores 2875 versus Intel's 2060, a 39.6% advantage. The single-core R15 test shows a similar gap: 405 versus 290, a 39.7% lead for AMD. Cinebench R20 multicore results continue the pattern, with AMD scoring 11982 against Intel's 8586, a 39.6% delta. The R20 single-core test shows AMD at 1691 versus Intel's 1212, a 39.5% advantage. Cinebench R23 multicore has AMD at 28529 and Intel at 20445, a 39.5% delta, and R23 single-core has AMD at 4027 versus Intel's 2886, also a 39.5% lead. The consistency of these deltas, all hovering near 39.5-39.7%, indicates a systematic per-core performance edge for the AMD architecture in Cinebench workloads.

PassMark tests reveal a broader performance spread. The data compression test shows AMD at 416331 versus Intel's 258704, a 60.9% lead for AMD. Data encryption has AMD at 21186 against Intel's 14253, a 48.6% advantage. The extended instructions test shows the largest gap: AMD scores 29351, Intel scores 15952, giving AMD an 84% lead. Integer math follows with AMD at 119521 versus Intel's 82411, a 45% delta. Random string sorting has AMD at 45358 against Intel's 28973, a 56.6% advantage. Floating point math shows AMD at 74626 versus Intel's 60673, a 23% lead. The multithread PassMark test has AMD at 33689 and Intel at 24054, a 40.1% delta. Single-thread PassMark results show AMD at 3914 versus Intel's 3433, a 14% lead.

The Intel chip's wins are narrower. In the find prime numbers test, Intel scores 142 versus AMD's 125, a 12% advantage for Intel. The physics test has Intel at 1917 against AMD's 1843, a 3.9% lead for Intel. These two wins suggest that Intel's architecture retains an edge in specific integer-heavy or physics-simulation workloads, but the magnitude of those wins is far smaller than the AMD leads in most other tests.

Looking at overall averages, the AMD Ryzen AI 9 HX PRO 375 has an average benchmark score of 47022, placing it in the 89th percentile of all CPUs. The Intel Core 9 273PTE averages 31143, placing it in the 82nd percentile. The nearest rivals for the AMD chip include the AMD Ryzen 9 5900 with an average score of 46971 (0.1% delta) and the Intel Core i7-13700K at 46881 (0.3% delta). The Intel chip's nearest rivals include the Intel Core i7-12700F at 31081 (0.2% delta) and the AMD Ryzen 9 8945HS at 31074 (0.2% delta).

The boost clocks reverse the order: AMD at 5.10 GHz versus Intel at 5.50 GHz. The TDP differs substantially, with AMD at 28 W and Intel at 45 W. The AMD chip uses an AMD Socket FP8, while the Intel chip uses Intel Socket 1700.

The cache hierarchy differs in L2 and L3. Both have 80 KB of L1 per core, but AMD has 1 MB of L2 per core versus Intel's 2 MB per core. The L3 cache is 16 MB for AMD and 36 MB shared for Intel. Process nodes differ, with AMD on 4 nm from TSMC and Intel on 10 nm from Intel. The AMD die size is listed at 233 mm², while the Intel die size is not recorded. Memory support differs: AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. PCIe generations differ, with AMD at Gen 4 and Intel at Gen 5, both with 16 lanes (CPU only). Integrated graphics differ, with AMD using Radeon 890M and Intel using UHD Graphics 730. The AMD processor has a part number of 100-000001683, while the Intel processor has part number SA4QJ. The Intel chip has a launch MSRP of $549. The release dates differ, with AMD arriving on January 5, 2025, and Intel on March 8, 2026.

The Verdict

The data supports a clear split based on workload and platform requirements. The AMD Ryzen AI 9 HX PRO 375 is the stronger processor in the vast majority of benchmark comparisons. It leads by roughly 39.5% across all Cinebench iterations, both single-core and multi-core, and extends that lead to 84% in extended instructions, 60.9% in data compression, and 56.6% in random string sorting. Its average benchmark score of 47022 sits in the 89th percentile, and it compares favorably to desktop parts like the Intel Core i7-13700K, which scores 46881 with a 0.3% delta. The AMD chip also does this at a 28 W TDP, making it suitable for mobile systems.

The Intel Core 9 273PTE is a desktop processor with a 45 W TDP and a higher 5.50 GHz boost clock. It wins only two head-to-head tests: find prime numbers by 12% and physics by 3.9%. Its 36 MB of L3 cache and 2 MB of L2 per core do not translate into broad benchmark victories, and its average score of 31143 places it in the 82nd percentile, roughly on par with the Intel Core i7-12700F. The Intel chip does offer PCIe Gen 5 support and DDR4 compatibility, which may matter for specific desktop builds, but the recorded performance data shows AMD ahead in nearly every compute-intensive test.

For users choosing between these two, the AMD Ryzen AI 9 HX PRO 375 is the pick for raw performance in Cinebench rendering, encryption, compression, and integer math workloads, and it does so at lower power. The Intel Core 9 273PTE is the pick for desktop systems requiring PCIe Gen 5, DDR4 support, or the specific physics and prime-number workloads where it holds a small advantage. The database shows the AMD chip with a 15-2 win record in head-to-head benchmarks, and that margin is reflected in the overall average scores and percentiles.
