Architecture Differences

The two processors come from different manufacturing and design philosophies. The AMD Ryzen AI 7 450G is built on a 4 nm process at TSMC and uses the Gorgon Point codename, part of the Ryzen AI 400 generation based on Zen 5 and Zen 5c cores. The Intel Core 5 223PE uses a 10 nm process at Intel, with the Bartlett Lake codename and Core 5 generation branding. The die size for AMD is recorded at 195 mm², while no die size is listed for Intel.

Cache layouts differ notably. Both parts have 80 KB of L1 cache per core and 1 MB of L2 per core for AMD versus 2 MB per core for Intel. The L3 cache is where the bigger disparity appears: AMD has 8 MB of L3, while Intel has 24 MB shared. This larger L3 on the Intel part likely contributes to its strong performance in physics and floating point tests, where larger working sets can stay resident on-chip.

Memory support shows a split: AMD supports DDR5 and LPDDR5X, while Intel supports DDR4 and DDR5. Both run dual-channel memory with identical memory bandwidth of 89.6 GB/s, and both support ECC memory. PCIe connectivity differs, with AMD offering Gen 4 with 12 lanes from the CPU, while Intel offers Gen 5 with 16 lanes. The integrated graphics also differ: AMD uses the Radeon 860M, while Intel uses UHD Graphics 730. The AMD part has an unlocked multiplier, while the Intel part is locked. The AMD chip uses the AM5 socket, Intel uses Socket 1700. The AMD part has a launch MSRP of $232, while no launch MSRP is recorded for the Intel part.

The Verdict

The data points to distinct purchasing decisions based on workload priorities. The AMD Ryzen AI 7 450G offers a higher overall average benchmark score of 63331, placing it in the 93rd percentile, which is 6 points higher than the Intel part's 87th percentile. Its nearest rivals in the database include the Intel Core Ultra 7 265HX with an average score of 63173 (0.2% delta), the Intel Core i7-13790F at 63080 (0.4% delta), and the AMD Ryzen AI Max PRO 390 at 63765 (-0.7% delta). This places the AMD chip in a performance tier that competes with higher-end desktop and mobile parts.

The Intel Core 5 223PE, with an average score of 40585, sits in a different tier. Its nearest rivals are the Intel Core 7 253PE at 40557 (0.1% delta), the Intel Xeon 6357P at 40630 (-0.1% delta), and the Intel Core Ultra X7 368H at 40518 (0.2% delta). The average score gap between the two reviewed parts is substantial, around 36%, but the Intel chip still holds specific workload advantages.

For users prioritizing compression workloads, encryption, random string sorting, or single-thread performance, the AMD Ryzen AI 7 450G is the clear choice from the data. It also wins on overall average score and percentile ranking. For users running physics simulations, prime number computations, or floating point heavy applications, the Intel Core 5 223PE delivers superior results. The multithread score slightly favors Intel, suggesting that general multi-threaded workloads without specific data-handling patterns may see a small benefit from the Intel part. The AMD part's higher average score and better single-thread performance make it the more balanced option, while the Intel part is specialized for certain computational tasks.
