AMD Ryzen 9 7940H vs Intel Core 5 223PE Comparison

Both the Intel Core 5 223PE and the AMD Ryzen 9 7940H land in the 87th percentile of all CPUs, with near-identical average benchmark scores (40585 vs 40431). The Intel part edges ahead by a razor-thin 0.4% overall, but the two chips achieve that parity through completely different workloads. This is a matchup where the synthetic rendering tests favor Intel decisively, while the AMD chip claws back ground in specialized compute tasks, making the choice a matter of workload priorities rather than raw generational dominance.

Head-to-Head Benchmarks

The Cinebench suite is a clean sweep for the Intel Core 5 223PE, and the margins are consistent. In Cinebench R15, R20, and R23, the Intel chip wins both single-core and multi-core by exactly 7.1% in every test. The R23 multi-core score of 26455 versus 24703 is a meaningful gap for heavily threaded rendering, and the R23 single-core result of 3734 against 3487 shows that the Intel part’s boost clock advantage translates directly into per-thread performance. The same 7.1% delta appears in Passmark’s multithread test, where the Intel chip scores 31124 against 29063.

The Intel chip’s biggest wins, however, come in two specialized Passmark subtests. In find_prime_numbers, the Intel part scores 159 against AMD’s 81, a 96.3% advantage that suggests a fundamental efficiency difference in this particular integer workload. The Passmark physics test shows a similar story, with the Intel chip scoring 2493 versus 1300, a 91.8% lead. Both of these results are outliers in magnitude compared to the rest of the benchmark suite, indicating that the Intel architecture handles these specific instruction patterns far better than the AMD part. Floating point math also favors Intel by 23.2%, with scores of 76468 versus 62057.

The AMD Ryzen 9 7940H does not go down quietly. Its strongest counterattack comes in data encryption, where it scores 21096 against Intel’s 18448, a 12.6% lead. Random string sorting is another clear AMD win, with a score of 42093 versus 35798, a 15% advantage. The AMD chip also takes data compression by a slim 1.5% margin (352077 vs 346623), extended instructions by 8% (26804 vs 24672), and integer math by 2.1% (101977 vs 99819). These five wins show that the AMD part is not merely competitive but superior in specific data-processing tasks, even if the overall average benchmark score remains slightly lower.

Where Each One Wins

The Intel Core 5 223PE is the pick for anyone whose workload looks like a rendering benchmark. Every Cinebench test, from R15 to R23, goes to Intel by the same 7.1% margin, which makes it the safer choice for video encoding, 3D rendering, and other tasks that scale across cores with consistent per-thread efficiency. The 96.3% lead in find_prime_numbers and the 91.8% lead in physics also point to strengths in scientific computing and simulation workloads that rely on heavy integer or physics calculations. The 23.2% advantage in floating point math further reinforces this profile, suggesting the Intel chip handles number-crunching tasks with notably better throughput.

The AMD Ryzen 9 7940H, by contrast, is the stronger choice for data manipulation and security-related workloads. The 12.6% lead in encryption is substantial, and the 15% advantage in random string sorting indicates better performance in database operations, text processing, or any task that shuffles large amounts of unstructured data. The 8% lead in extended instructions and the 2.1% lead in integer math round out a profile that favors compression, hashing, and general data transformation. For a developer or analyst running encryption, compression, or sorting tasks all day, the AMD part delivers measurable gains where it matters, even if its multi-core rendering scores lag behind.

Architecture Differences

The two chips come from fundamentally different design philosophies. The Intel Core 5 223PE is built on a 10 nm process at Intel’s own foundry, uses the Bartlett Lake codename, and targets the desktop market with an Intel Socket 1700. It is a desktop part with a 65 W TDP. The AMD Ryzen 9 7940H is a mobile chip on TSMC’s 4 nm process, using the Zen 4 architecture with the Phoenix codename, and fits an AMD Socket FP8. Its TDP is 35 W, reflecting its mobile focus.

Core counts are identical at 8 cores and 16 threads, and both chips boost to 5.20 GHz. The Intel part has a base clock of 2.90 GHz, while the AMD part starts at 4.00 GHz. Cache layouts differ significantly: Intel provides 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3, while AMD offers 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The AMD chip’s smaller cache is partially offset by its denser 4 nm process, which packs 25,000 million transistors into a 178 mm² die, though the Intel part’s transistor count and die size are not specified.

Memory support also diverges. The Intel chip supports both DDR4 and DDR5, while the AMD chip is DDR5-only, though both run dual-channel with identical 89.6 GB/s bandwidth. Both support ECC memory. PCIe connectivity differs, with the Intel part offering Gen 5 with 16 lanes (CPU only) versus AMD’s Gen 4 with 20 lanes (CPU only). Integrated graphics differ as well, with Intel’s UHD Graphics 730 against AMD’s Radeon 780M. The Intel chip has a launch MSRP of $232 and a release date in March 2026, while the AMD part has no listed MSRP or release date, and neither chip has an unlocked multiplier.

The Verdict

The benchmark data presents a clear split. The Intel Core 5 223PE is the superior processor for rendering, physics simulation, and floating-point-heavy compute, with a consistent 7.1% lead across all Cinebench tests and a 23.2% advantage in floating point math. Its 96.3% and 91.8% leads in find_prime_numbers and physics, respectively, make it the obvious choice for anyone running scientific or simulation workloads that stress those specific instruction paths.

The AMD Ryzen 9 7940H is the better option for data-centric tasks. Its 12.6% lead in encryption and 15% lead in random string sorting are significant for security, database, and data-processing applications, and its 8% advantage in extended instructions adds further weight. The 35 W TDP also makes it the more power-efficient part on paper, which matters in mobile or thermally constrained systems.

For a desktop builder prioritizing rendering and general compute, the Intel Core 5 223PE delivers more performance where it counts, despite its higher TDP. For a mobile user or anyone whose daily workload revolves around data compression, encryption, and sorting, the AMD Ryzen 9 7940H offers meaningful advantages that outweigh its slight deficit in aggregate benchmark scores. Choose based on the specific tasks you run most often, as the 0.4% overall average difference hides very different strengths.
