AMD Ryzen AI 9 HX PRO 470 vs Intel Core 9 273PE Comparison

The AMD Ryzen AI 9 HX PRO 470 and the Intel Core 9 273PE are both 12-core, 24-thread processors, but the benchmark data shows they are optimized for entirely different workloads. The head-to-head comparison reveals a split decision: Intel wins the majority of the tests with 8 wins, while AMD takes 7, but the margins in each direction tell a clear story about their respective strengths.

Head-to-Head Benchmarks

The most striking difference appears in the Cinebench suite. In Cinebench R23 multi-core, the Intel Core 9 273PE scores 31,288 against the AMD Ryzen AI 9 HX PRO 470's 19,095, a massive 39% advantage for Intel. This is the single largest gap in the entire comparison. The same pattern holds in Cinebench R15 multi-core, though with a much smaller margin: Intel leads 3,153 to 3,234? No, the data shows AMD actually wins that test, 3,234 versus 3,153, a 2.6% edge. The Cinebench R23 result is the outlier in the multi-core category, suggesting Intel's architecture scales better under sustained heavy loads.

Single-core performance is decisively Intel's territory. In Cinebench R23 single-core, Intel scores 4,417 versus AMD's 2,054, a 53.5% lead. Cinebench R15 single-core shows a similar picture with Intel at 445 and AMD at 313, a 29.7% margin. These are not minor differences; they indicate a fundamental advantage in Intel's core design for lightly threaded tasks.

The PassMark suite splits more evenly. AMD wins data compression decisively, scoring 461,195 against Intel's 405,885, a 13.6% advantage. Extended instructions also favor AMD heavily: 32,803 versus 24,630, a 33.2% lead. Random string sorting goes to AMD at 48,824 versus 45,098, an 8.3% margin. Single-thread performance in PassMark, however, shows AMD ahead at 4,050 versus Intel's 3,650, an 11% gain, which contradicts the Cinebench single-core results.

Intel takes the remaining PassMark tests. Floating point math shows Intel at 107,884 versus AMD's 80,023, a 25.8% lead. Physics goes to Intel with a 38.6% margin, scoring 3,120 against 1,915. Integer math favors Intel at 139,410 versus 127,573, an 8.5% edge. Find prime numbers gives Intel a 33% win, 203 versus 136. The multithread test is nearly a tie: Intel leads 36,810 to 36,402, just a 1.1% difference. Data encryption is also close, with AMD ahead by only 0.9%, 22,929 versus 22,719.

Where Each One Wins

The AMD Ryzen AI 9 HX PRO 470 is the clear choice for data-centric and compression-heavy workloads. Its wins in data compression, extended instructions, and random string sorting point to strong memory handling and instruction-level efficiency. The data encryption result, while narrow, reinforces this pattern. The PassMark single-thread score of 4,050 also suggests that AMD's Zen 5 cores handle certain single-threaded operations better than Intel's, even if Cinebench tells a different story.

The Intel Core 9 273PE dominates in raw computational throughput and physics simulation. The Cinebench R23 multi-core result is the headline, but the physics score of 3,120 versus 1,915 indicates a substantial advantage in floating-point-heavy simulation workloads. Floating point math and integer math both favor Intel, and the find prime numbers test shows its strength in iterative calculation tasks. The Cinebench single-core results, with margins of 29.7% and 53.5%, suggest Intel's cores are better suited for applications that rely heavily on a single thread, such as older games or legacy software.

The multithread PassMark score, where Intel leads by just 1.1%, shows that in mixed-threaded real-world scenarios, the two processors are effectively equivalent. The overall average benchmark scores reflect this split: AMD has a 92nd percentile ranking versus Intel's 90th, and AMD's average score of 56,306 is higher than Intel's 49,845, but this is skewed by the types of tests included.

Architecture Differences

The two processors come from different manufacturing philosophies. The AMD Ryzen AI 9 HX PRO 470 uses a 4 nm process from TSMC and is built on the Zen 5 architecture, codenamed Gorgon Point. It is part of the Ryzen AI PRO 400 generation, which uses a mix of Zen 5 and Zen 5c cores. The die size is 233 mm². Intel's Core 9 273PE uses a 10 nm process from Intel's own foundry, codenamed Bartlett Lake, and belongs to the Core 9 generation. Intel does not list a die size in the data.

Cache configurations differ significantly. Both have 80 KB of L1 cache per core, but AMD's L2 is 1 MB per core while Intel's is 2 MB per core. The L3 cache tells the bigger story: AMD has 16 MB total, while Intel has 36 MB shared. This larger Intel L3 cache likely contributes to its multi-core Cinebench performance, as more data can be stored closer to the cores.

Memory support also diverges. AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both run dual-channel with identical memory bandwidth of 89.6 GB/s, and both support ECC memory. PCIe connectivity differs: AMD offers Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). The integrated graphics are also different, with AMD using the Radeon 890M and Intel using UHD Graphics 730.

The socket and market segment reflect their intended platforms. AMD uses Socket FP8 and is marked as a mobile processor, while Intel uses Socket 1700 and is positioned as a desktop part. This explains the TDP difference: AMD is rated at 28 watts, while Intel is rated at 65 watts. The base and boost clocks also differ, with AMD at 2.00 GHz base and 5.20 GHz boost, while Intel runs at 2.30 GHz base and 5.70 GHz boost. Neither has an unlocked multiplier.
