Architecture Differences

The AMD Ryzen AI 9 HX PRO 475 uses the Zen 5 architecture on a 4 nm TSMC process node, with the codename Gorgon Point. It belongs to the Ryzen AI PRO 400 generation, which combines Zen 5 and Zen 5c cores. The die size is 233 mm². The Intel Core 9 273PQE uses the Bartlett Lake codename and is manufactured on Intel's 10 nm process node, belonging to the Core 9 generation. It does not have a listed architecture name in the database.

The AMD chip has 80 KB of L1 cache per core and 1 MB of L2 cache per core, with 16 MB of L3 cache. The Intel chip also has 80 KB of L1 cache per core, but doubles the L2 to 2 MB per core and provides 36 MB of shared L3 cache. This gives the Intel part a substantial cache advantage, particularly in L3 where it has more than double the capacity.

Memory support differs significantly. The AMD processor supports DDR5 and LPDDR5X memory, while the Intel processor supports DDR4 and DDR5. Both are dual-channel with 89.6 GB/s memory bandwidth and both support ECC memory. The PCIe interface also differs: AMD uses Gen 4 with 16 CPU-only lanes, while Intel uses Gen 5 with 16 CPU-only lanes.

The integrated graphics differ as well. The AMD chip includes Radeon 890M graphics, while the Intel chip uses UHD Graphics 770. The AMD processor is designed for mobile segments, while the Intel processor is a desktop part. Their sockets are also different: AMD Socket FP8 versus Intel Socket 1700.

Head-to-Head Benchmarks

The database records 11 head-to-head benchmark comparisons, and the Intel Core 9 273PQE wins all 11. The AMD Ryzen AI 9 HX PRO 475 does not secure a single victory in the recorded passmark tests. The largest gap appears in floating point math, where Intel scores 125546 versus AMD's 79887, a delta of -36.4% for AMD.

The data compression test shows Intel at 585752 against AMD's 461650, a -21.2% delta. Data encryption follows a similar pattern: Intel scores 29636 versus AMD's 23132, a -21.9% gap. Integer math also favors Intel strongly, with 164629 versus 126829, a -23% difference. The find prime numbers test shows Intel at 198 versus AMD's 130, a -34.3% gap, which indicates a substantial advantage in that specific workload.

The multithread test places Intel at 46107 versus AMD's 36487, a -20.9% difference. Physics calculations show Intel at 2754 versus AMD's 1877, a -31.8% delta. Extended instructions score Intel at 38743 versus AMD's 31969, a -17.5% gap. Random string sorting is the closest contest, with Intel at 53167 versus AMD's 48894, a -8% difference.

Single-thread performance is also led by Intel, though by a smaller margin. The Intel chip scores 4573 versus AMD's 4301, a -5.9% delta. This pattern holds across both single-thread test entries in the database.

The average benchmark scores reflect this dominance. The AMD chip has an average benchmark score of 74496, while the Intel chip averages 66099. However, the nearest rival comparisons tell a more nuanced story. The AMD processor sits at the 94th percentile of all CPUs, with its closest rival being the AMD Ryzen 9 9950X at -0.2% delta and the AMD Ryzen 7 PRO 9745 at -0.4%. The Intel processor sits at the 93rd percentile, with its closest rival being the Intel Core Ultra 5 250KF Plus at -0.1% delta.

The Verdict

The recorded data shows a decisive overall win for the Intel Core 9 273PQE across all 11 head-to-head passmark benchmarks. The Intel chip is ahead in every measured category, from compression and encryption to floating point and integer math. The widest margins occur in floating point math (-36.4%) and find prime numbers (-34.3%), while the narrowest margin is in single-thread performance (-5.9%).

However, the average benchmark scores complicate a simple verdict. The AMD chip has a higher average benchmark score (74496 versus 66099), and it sits at a higher percentile (94th versus 93rd). This suggests that the AMD processor may perform better in workloads not captured by the specific head-to-head tests recorded in the database. The AMD part also has a dramatically lower TDP (28 W versus 125 W), which is a major factor for mobile platforms.

The Intel chip's nearest rivals include the AMD Ryzen 9 7950X3D at a +0.3% delta, meaning the Intel part scores slightly higher than that processor in the database's averaging. The AMD chip's nearest rivals include the AMD Ryzen 9 9950X at -0.2%, indicating the AMD part scores just below that flagship. This places both processors in similar performance tiers despite the head-to-head sweep.

For users prioritizing the specific passmark workloads recorded, the Intel Core 9 273PQE is the clear choice. For users considering the broader average benchmark score and the mobile form factor, the AMD Ryzen AI 9 HX PRO 475 has its own advantages.

Where Each One Wins

The Intel Core 9 273PQE wins every recorded head-to-head benchmark. Its largest advantages are in floating point math, find prime numbers, and physics calculations, where it leads by more than 30% in each case. It also shows strong leads in integer math (-23%), multithread (-20.9%), data encryption (-21.9%), and data compression (-21.2%). The smallest lead is in random string sorting at -8% and single-thread performance at -5.9%.

The AMD Ryzen AI 9 HX PRO 475 wins in no recorded head-to-head benchmark, but it has the higher average benchmark score of 74496 versus 66099, and a 94th percentile ranking versus 93rd for Intel. This indicates that outside the specific passmark tests, the AMD chip may hold an advantage in unmeasured workloads. The AMD chip also has a much lower TDP, making it suited for mobile platforms where power efficiency is critical.

The AMD processor uses the Radeon 890M integrated graphics, which is a stronger integrated solution than the Intel UHD Graphics 770 based on the naming convention, though no direct benchmark comparison is recorded. The AMD chip supports LPDDR5X memory, which is common in thin-and-light laptops, while the Intel chip supports DDR4 and DDR5, which is typical for desktop builds.

The Intel chip's PCIe Gen 5 support gives it an interface advantage for high-bandwidth peripherals, while the AMD chip's PCIe Gen 4 is more conservative. Both support ECC memory, which matters for workstation use. The Intel chip has a higher base clock (3.40 GHz versus 2.00 GHz) and a higher boost clock (5.90 GHz versus 5.20 GHz), which contributes to its single-thread lead.

For users who rely on the specific passmark tests recorded, the Intel Core 9 273PQE is the stronger pick. For users who value the higher average benchmark score, the 94th percentile ranking, and the mobile form factor with lower power draw, the AMD Ryzen AI 9 HX PRO 475 presents a compelling alternative.
