AMD Ryzen AI 7 450G vs Intel Core 9 273PE Comparison

The Verdict

The benchmark data splits these two desktop processors cleanly by workload type. The AMD Ryzen AI 7 450G wins the single-thread and extended instruction tests, while the Intel Core 9 273PE dominates multi-threaded and math-heavy workloads. For users whose primary tasks are lightly threaded, such as general responsiveness or older applications, the AMD part is the stronger choice based on its 18.1% lead in PassMark single-thread performance. For users running heavily threaded workloads, including compression, encryption, physics simulation, or floating-point math, the Intel processor is clearly ahead, with wins in 8 of the 11 recorded head-to-head benchmarks.

The Intel Core 9 273PE also holds a 90th percentile ranking among all CPUs, while the AMD Ryzen AI 7 450G sits at the 93rd percentile. The AMD part’s higher percentile is driven by its strong single-thread score and efficient average across tests, but the Intel part’s raw multi-thread output is substantially higher. The data indicates that the Intel processor is the better pick for compute-heavy tasks, while the AMD processor is the better pick for single-thread responsiveness and vectorized instruction workloads. The Intel part carries a launch MSRP of $549; the AMD part has no recorded launch MSRP.

Architecture Differences

The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation built on Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC. The Intel Core 9 273PE uses the Bartlett Lake codename and belongs to the Core 9 generation, built on a 10 nm process at Intel. These process differences are significant: the AMD part uses a smaller node, which typically contributes to its higher single-thread efficiency, while the Intel part uses a larger node but compensates with more cores and threads.

The core counts differ substantially. The AMD processor has 8 cores and 16 threads, while the Intel processor has 12 cores and 24 threads. Both have 80 KB of L1 cache per core, but the L2 cache differs: AMD provides 1 MB per core, while Intel provides 2 MB per core. The L3 cache also differs greatly, with AMD offering 8 MB total and Intel offering 36 MB shared. That larger shared L3 cache on the Intel part likely supports its strong multi-threaded performance in cache-sensitive workloads.

Memory support differs as well. The AMD processor supports DDR5 and LPDDR5X, while the Intel processor supports DDR4 and DDR5. Both use a dual-channel memory bus with 89.6 GB/s bandwidth, and both support ECC memory. The PCIe capabilities differ: AMD uses Gen 4 with 12 lanes (CPU only), while Intel uses Gen 5 with 16 lanes (CPU only). Integrated graphics also differ, with AMD featuring Radeon 860M and Intel featuring UHD Graphics 730. The AMD part has an unlocked multiplier, while the Intel part is locked. The AMD processor uses AMD Socket AM5, while the Intel processor uses Intel Socket 1700.

Where Each One Wins

The PassMark single-thread test is the clearest AMD victory. The Ryzen AI 7 450G scores 4309 against the Intel Core 9 273PE’s 3650, an 18.1% advantage. This suggests the AMD part is better suited for applications that rely on a single core, such as legacy software, many database queries, or lightly threaded productivity tasks. The extended instructions test also favors AMD, with a score of 28223 versus 24630, a 14.6% margin. This indicates an advantage in workloads that use specialized CPU instruction sets, such as cryptography or media codecs.

The Intel part wins every other recorded benchmark. The largest margins come in prime number finding, where Intel scores 203 against AMD’s 87, a 57.1% advantage. Physics simulation also heavily favors Intel, with a score of 3120 versus 1440, a 53.8% lead. Floating-point math shows Intel ahead by 41%, scoring 107884 versus 63683. Integer math favors Intel by 28.5%, with scores of 139410 versus 99732. Multi-threaded performance shows Intel leading by 17.4%, scoring 36810 versus 30422. Data encryption favors Intel by 16.6%, with scores of 22719 versus 18937. Random string sorting favors Intel by 5.4%, and data compression favors Intel by a narrow 0.8%, with scores of 405885 versus 402831.

The win split is 3 for AMD and 8 for Intel across the head-to-head benchmarks. Users should choose the AMD part for single-thread and extended instruction workloads, and the Intel part for everything else in the recorded tests, particularly math, physics, and multi-threaded tasks.

Head-to-Head Benchmarks

The largest Intel win is in the PassMark find prime numbers test. Intel scores 203 against AMD’s 87, a 57.1% margin. This is a workload that stresses integer division and branch prediction, and the Intel part’s higher core count and larger cache appear to deliver a decisive advantage. The physics test shows a similar pattern, with Intel at 3120 versus AMD’s 1440, a 53.8% lead. Physics benchmarks typically scale with thread count and memory bandwidth, both of which favor the Intel part.

The floating-point math test shows Intel at 107884 versus AMD’s 63683, a 41% lead. This is a substantial gap for a workload that is common in scientific computing, 3D rendering, and simulation.
