Architecture Differences

The AMD Ryzen AI 7 450G uses the Gorgon Point codename with a Zen 5 / Zen 5c hybrid core layout on a 4 nm TSMC process. The die measures 195 mm². The Intel Core i7-14650HX is built on Raptor Lake-HX architecture, a refresh of the Core 14th Gen series, using a 10 nm Intel process on a 257 mm² die. AMD integrates 8 cores and 16 threads; Intel deploys 16 cores and 24 threads. Both share the same 80 KB L1 per core, but L2 differs: AMD gives 1 MB per core, Intel doubles that to 2 MB per core. L3 is a major split, with AMD offering 8 MB total and Intel providing 30 MB shared.

The AMD part operates with a 2.00 GHz base clock and 5.10 GHz boost clock, while Intel runs a 2.20 GHz base and 5.20 GHz boost. TDP ratings are close: AMD lists 65 watts, Intel lists 55 watts. Socket types diverge completely: AMD uses Socket AM5 with a desktop market segment, while Intel uses BGA 1964 for mobile. PCIe support differs as well, AMD provides Gen 4 with 12 CPU lanes, Intel provides Gen 5 with 16 CPU lanes. Integrated graphics are Radeon 860M on AMD versus UHD Graphics 710 on Intel. Both support ECC memory, and both have unlocked multipliers.

Head-to-Head Benchmarks

The PassMark suite shows a clear split between the two processors. AMD wins 4 of the 11 recorded head-to-head tests, Intel wins 7. The largest AMD victory comes in extended instructions, where the Ryzen AI 7 450G scores 28223 against Intel's 24150, a 16.9% margin. AMD also leads in single-thread performance with a 12.2% advantage (4309 versus 3841), data compression with a narrow 1.1% edge (402831 versus 398418), and the duplicate single-thread test confirms the same 12.2% gap.

Intel's wins are broader in magnitude. The biggest is find prime numbers, where Intel scores 152 against AMD's 87, a 42.8% lead. Floating-point math follows with Intel ahead by 25.1% (84999 versus 63683). Physics shows a 34.6% Intel advantage (2202 versus 1440). Data encryption favors Intel by 17.4% (22917 versus 18937), and integer math gives Intel a 14.5% edge (116661 versus 99732). Multithread performance goes to Intel by 9.2% (33495 versus 30422). Random string sorting is nearly a tie, with Intel ahead by only 0.9% (43035 versus 42663).

Context from the database matters here. AMD's average benchmark score of 63331 places it among rivals like the Intel Core Ultra 7 265HX (63173, 0.2% delta), the Intel Core i7-13790F (63080, 0.4% delta), and the AMD Ryzen AI Max PRO 390 (63765, -0.7% delta). Intel's average of 41576 sits near the Intel Core Ultra 7 265H (41621, -0.1% delta) and the Intel Core 7 251TE (41650, -0.2% delta). The two processors occupy different performance tiers in the overall database, despite the head-to-head results showing Intel winning more individual tests.

The Verdict

The data indicates that the AMD Ryzen AI 7 450G is the stronger overall processor in the recorded benchmark database. Its average benchmark score of 63331 is roughly 52% higher than Intel's 41576, and it holds the 93rd percentile versus Intel's 88th. The single-thread advantage of 12.2% is substantial for responsiveness and lightly threaded workloads. The extended instructions lead of 16.9% suggests better efficiency in specialized instruction sets.

The Intel Core i7-14650HX wins the majority of individual tests, but those wins concentrate in heavily parallel or math-intensive workloads. The 42.8% lead in prime number finding and the 25.1% lead in floating-point math are large, but they do not compensate for the lower overall average score. The multithread win of 9.2% (33495 versus 30422) is real, yet the AMD chip's higher average across all benchmarks indicates more consistent performance. Users who prioritize single-core speed and overall benchmark standing should pick the AMD part. Users who need maximum throughput in math-oriented or physics-heavy tasks should pick the Intel part.

Its 4309 single-thread score beats Intel's 3841 by 12.2%, which benefits general desktop use, application launching, and web browsing. The data compression score of 402831 edges out Intel's 398418 by 1.1%, useful for file archiving and decompression tasks. Extended instructions at 28223 versus 24150 gives AMD a 16.9% edge in workloads that leverage modern CPU instruction sets. The 93rd percentile ranking relative to all CPUs makes it the stronger choice for users who want a chip that scores well across the entire database.

The Intel Core i7-14650HX wins in multithread performance, physics, floating-point math, integer math, data encryption, find prime numbers, and random string sorting. The 33495 multithread score versus AMD's 30422 shows a 9.2% advantage for heavily threaded applications such as video rendering or scientific simulation. Physics at 2202 versus 1440 is a 34.6% lead, making it better for physics calculations in engineering or gaming workloads. Floating-point math at 84999 versus 63683 gives Intel a 25.1% margin, and integer math at 116661 versus 99732 provides a 14.5% edge. Data encryption at 22917 versus 18937 is 17.4% faster, and find prime numbers at 152 versus 87 is 42.8% faster, indicating superior number-crunching capability. Random string sorting at 43035 versus 42663 is a marginal 0.9% win.

The database shows that the choice depends on workload type. AMD delivers a higher average score and better single-thread results, while Intel offers decisive wins in math and multi-threaded tests. The AMD part also provides a higher memory bandwidth figure at 89.6 GB/s, though Intel counters with newer PCIe Gen 5 support and double the L3 cache. Desktop buyers should favor AMD for its Socket AM5 and Radeon 860M graphics; mobile system designers should favor Intel for its BGA 1964 socket and UHD Graphics 710.
