AMD Ryzen AI 9 HX 375 vs Intel Core 7 253PTE Comparison

The AMD Ryzen AI 9 HX 375 and the Intel Core 7 253PTE are two fundamentally different processors, separated by architecture, market segment, and performance profile. The benchmark data records 15 head-to-head comparisons, with the AMD part taking 13 wins and the Intel part taking 2. Despite the Intel chip’s higher single-core Cinebench scores, the AMD processor delivers a broader, more consistent advantage across most workloads, particularly in multi-threaded and data-intensive tasks. The average benchmark scores confirm this: the Ryzen AI 9 HX 375 averages 46030 points versus 34962 for the Core 7 253PTE, a 31.6% gap. The Intel part does hold a clear lead in one specific area, but the overall picture favors AMD.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 dominates in nearly every measured category, with its largest margins appearing in extended instruction throughput and data compression. The recorded data shows the AMD chip winning 13 of 15 benchmarks, including all PassMark sub-tests and both multi-core Cinebench runs. Its advantages range from a narrow 1.8% in PassMark integer math to a commanding 71.2% in extended instructions. The AMD processor also leads in real-world style workloads: data compression by 46.8%, random string sorting by 57.8%, and data encryption by 34.2%. These results indicate a processor that handles parallel, data-heavy tasks with clear superiority.

The Intel Core 7 253PTE wins only two benchmarks, both single-core Cinebench tests. It edges out the AMD chip by 0.3% in Cinebench R15 single-core (302 versus 301) and delivers a substantial 33.8% advantage in Cinebench R23 single-core (3003 versus 1988). This latter result is the single largest win for either processor in any test. The Intel part’s single-thread PassMark score is actually lower than AMD’s (3794 versus 3867, a 1.9% deficit), so its Cinebench single-core strength appears specific to that rendering workload rather than a general single-thread advantage.

Architecture Differences

The two processors come from opposite design philosophies. The AMD Ryzen AI 9 HX 375 uses a Zen 5 architecture on a 4 nm TSMC process, built as the Strix Point codename from the Ryzen AI 300 generation. It combines Zen 5 and Zen 5c cores, with 12 cores and 24 threads. The Intel Core 7 253PTE uses the Bartlett Lake codename on a 10 nm Intel process, with 10 cores and 20 threads. The AMD chip is a mobile part on AMD Socket FP8, while the Intel chip is a desktop part on Intel Socket 1700.

Cache configurations differ notably. The AMD processor provides 80 KB of L1 per core and 1 MB of L2 per core, with a shared 16 MB L3 cache. The Intel processor also has 80 KB of L1 per core but doubles L2 to 2 MB per core and offers a much larger 33 MB shared L3 cache. Memory support diverges as well: AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both run dual-channel memory with identical 89.6 GB/s bandwidth. Intel enables ECC memory support, which AMD does not. PCIe generations differ: AMD uses Gen 4 with 16 CPU lanes, while Intel uses Gen 5 with 16 CPU lanes.

Integrated graphics present another clear distinction. The AMD part carries the Radeon 890M, while the Intel part has UHD Graphics 730. The AMD processor also has a lower TDP of 28 watts versus 45 watts for the Intel part, despite delivering higher multi-core performance in the recorded benchmarks.

Head-to-Head Benchmarks

The Cinebench results tell a split story. In Cinebench R23 multi-core, the AMD Ryzen AI 9 HX 375 scores 21812 versus 21276 for the Intel Core 7 253PTE, a 2.5% win. The margin grows significantly in Cinebench R15 multi-core, where AMD leads 3334 to 2144, a 55.5% advantage. The older R15 test appears to amplify the AMD chip’s multi-threaded lead. In single-core Cinebench, the tables turn. The Intel part wins R23 single-core by 33.8% (3003 versus 1988) and R15 single-core by a hair at 0.3% (302 versus 301).

The PassMark suite shows consistent AMD dominance across diverse workloads. In multi-thread performance, AMD leads 32916 to 25031, a 31.5% gap. Physics simulation favors AMD by 38% (1819 versus 1318). Data compression shows AMD at 404918 versus 275828, a 46.8% lead. Encryption follows at 34.2% (20802 versus 15500). Extended instructions, which measure SIMD and specialized instruction throughput, show the largest gap: 29269 versus 17099, a 71.2% advantage for AMD. Prime number finding goes to AMD by 48.8% (122 versus 82). Floating point math favors AMD by 11.8% (75153 versus 67209), while integer math is nearly even at 1.8% (121754 versus 119552). Random string sorting shows AMD ahead by 57.8% (44552 versus 28227). Single-thread PassMark results are close, with AMD ahead 3867 to 3794, a 1.9% margin.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen AI 9 HX 375 has 12 cores and 24 threads, while the Intel Core 7 253PTE has 10 cores and 20 threads. Base clocks are 2.00 GHz for AMD and 1.80 GHz for Intel, but boost clocks reverse the order: AMD boosts to 5.10 GHz, while Intel reaches 5.40 GHz. TDP differs substantially, with AMD at 28 watts and Intel at 45 watts. The process node also differs, with AMD on 4 nm versus Intel on 10 nm, and the foundries are TSMC for AMD and Intel for the Intel part.

Cache layouts show Intel’s larger total capacity. AMD provides 16 MB of L3 shared, while Intel provides 33 MB shared. L2 cache per core is 1 MB for AMD and 2 MB for Intel. Both use 80 KB L1 per core. Memory support differs in type, with AMD supporting DDR5 and LPDDR5X versus Intel supporting DDR4 and DDR5, though both are dual-channel with 89.6 GB/s bandwidth. ECC memory is supported only on the Intel part. PCIe connectivity favors Intel with Gen 5 versus AMD’s Gen 4, both with 16 CPU lanes. The integrated graphics units are the Radeon 890M for AMD and UHD Graphics 730 for Intel. The Intel part has a launch MSRP of $384.

The Verdict

The data points to the AMD Ryzen AI 9 HX 375 as the stronger overall processor. It wins 13 of 15 head-to-head benchmarks, holds a 31.6% lead in average benchmark score, and achieves this with a 28 watt TDP versus 45 watts for the Intel part. Its advantages are broad, covering multi-core rendering, data compression, encryption, physics, and floating-point math. The largest margins come in extended instructions, where AMD leads by 71.2%, and random string sorting, where it leads by 57.8%. For any workload that scales across cores or uses data-heavy operations, the recorded data strongly favors the AMD chip.

The Intel Core 7 253PTE has a specific strength in Cinebench R23 single-core, where it leads by 33.8%. This suggests an edge in lightly threaded rendering tasks that rely on that benchmark engine. However, its single-thread PassMark score is actually lower than AMD’s, so this advantage does not generalize. The Intel part also offers ECC memory support, PCIe Gen 5, and a larger 33 MB shared L3 cache, which may matter for specific desktop use cases. Its higher TDP of 45 watts and desktop socket placement position it differently from the mobile AMD part.

Given the benchmark results, the AMD Ryzen AI 9 HX 375 is the pick for users who need multi-threaded throughput, data processing, and broad application performance in a lower-power package. The Intel Core 7 253PTE makes sense for scenarios where its single-core Cinebench lead and desktop features like ECC memory and PCIe Gen 5 outweigh the AMD chip’s sweeping multi-core dominance. The average benchmark scores make the overall hierarchy clear: AMD at 46030 versus Intel at 34962.
