AMD Ryzen AI 7 450 vs Intel Core 5 223PE Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core 5 223PE, which wins 14 of 15 head-to-head comparisons. The AMD Ryzen AI 7 450 manages only a single win, and that victory is narrow: a 1.8% edge in Cinebench R15 multi-core, scoring 2713 against 2666. That lone result aside, the Intel part dominates nearly every workload category, often by substantial margins.

The most dramatic gaps appear in single-core performance. In Cinebench R23 single-core, the Intel Core 5 223PE scores 3734 versus 2038 for the AMD, a 45.4% advantage. Cinebench R15 single-core tells a similar story: Intel scores 376 against 215, a 42.8% lead. These are not marginal differences; they indicate a fundamental advantage in per-thread throughput. The PassMark single-thread test confirms the pattern, with Intel at 4219 versus 3901, a 7.5% lead.

Multi-core results are more nuanced but still favor Intel. Cinebench R23 multi-core shows Intel at 26455 against 18316, a 30.8% advantage. The PassMark multi-thread score gives Intel 31124 versus 26350, a 15.3% lead. Interestingly, the older Cinebench R15 multi-core test flips the result, but only slightly, suggesting that the AMD part's 8-core, 16-thread configuration can occasionally edge ahead in legacy workloads. The R15 result, however, stands as the exception rather than the rule.

Memory-sensitive and encryption workloads further favor Intel. PassMark data encryption shows Intel at 18448 versus 16247, an 11.9% lead. Data compression scores 346623 for Intel against 315906 for AMD, an 8.9% edge. Extended instruction performance follows the trend: 24672 for Intel versus 22400 for AMD, a 9.2% difference.

The largest single delta appears in PassMark find prime numbers, where Intel scores 159 against 89, a 44% advantage. Floating-point math also heavily favors Intel: 76468 versus 54447, a 28.8% gap. Integer math gives Intel 99819 against 88531, an 11.3% lead. Physics simulation scores 2493 for Intel versus 1578 for AMD, a 36.7% difference. Even the closest non-R15 result, random string sorting, goes to Intel: 35798 versus 35648, a marginal 0.4% edge.

Looking at overall averages, the Intel part records an average benchmark score of 40585, while the AMD part averages 39485. Both CPUs sit at the 87th percentile versus all CPUs in the database, meaning they occupy the same tier globally. Yet within that tier, the Intel part consistently outperforms across the recorded test suite, with the AMD part's sole win being too small to offset the breadth of Intel's victories.

The Verdict

The data points to a clear conclusion: the Intel Core 5 223PE is the stronger processor in nearly every measurable dimension. It wins 14 of 15 head-to-head comparisons, with advantages ranging from 0.4% to 45.4%. The only AMD win, Cinebench R15 multi-core, is a 1.8% margin that does not compensate for the scale of Intel's dominance elsewhere.

For users prioritizing raw performance, especially single-core responsiveness and floating-point throughput, the Intel part is the obvious choice. Its 45.4% lead in Cinebench R23 single-core and 28.8% lead in floating-point math are decisive. The Intel part also leads in multi-core Cinebench R23 by 30.8%, which matters for rendering and compilation workloads. The AMD Ryzen AI 7 450 does not surpass Intel in any significant synthetic workload category beyond that single legacy R15 result.

The AMD part's case rests on secondary factors rather than benchmark victories. It operates at a 28 W TDP versus Intel's 65 W, making it substantially more power-efficient on paper. It also uses a 4 nm process node from TSMC, while Intel uses a 10 nm node from its own foundry. For systems where thermals and energy consumption take priority over peak scores, the AMD part may be preferable, but the recorded benchmarks do not show any performance area where AMD leads meaningfully.

Both CPUs share an 87th percentile ranking, so neither is a weak performer. The Intel part, however, delivers higher scores in the vast majority of tests. Users who buy for benchmark performance should choose Intel. Users who buy for efficiency and still want competitive, if usually trailing, performance can consider the AMD part, but they should expect to give up substantial single-core and multi-core throughput.

Where Each One Wins

The Intel Core 5 223PE wins across the broadest possible range of workload types. Single-core tests, both Cinebench and PassMark variants, go to Intel by margins from 7.5% to 45.4%. Multi-core Cinebench R23 goes to Intel by 30.8%. Encryption, compression, extended instructions, prime number finding, floating-point math, integer math, multithreaded PassMark, physics simulation, and random string sorting all go to Intel. There is no coherent category of benchmark where the AMD part consistently wins, aside from the single Cinebench R15 multi-core test.

The AMD Ryzen AI 7 450 does have one niche: legacy multi-core workloads. Its Cinebench R15 multi-core score of 2713 beats Intel's 2666, a 1.8% margin. This suggests that in older software optimized for the R15 rendering path, the AMD part can edge ahead, but the effect is small and isolated. No other benchmark in the recorded data gives AMD a win.

The Intel part also shows particular strength in computation-heavy tasks. Its 44% lead in prime number finding and 36.7% lead in physics simulation indicate strong integer and physics throughput. Its 28.8% lead in floating-point math reinforces this. For scientific computing, simulation, and number-crunching workloads, the Intel part is the clear choice.

For general desktop responsiveness, the single-core scores matter most, and Intel wins there decisively. For content creation and rendering, the Cinebench R23 multi-core result favors Intel by a wide margin. For data compression and encryption, Intel leads by 8.9% and 11.9%, respectively. The AMD part's only realistic selling point from the data is its lower TDP and the associated thermal profile, not its benchmark scores.
