AMD Ryzen 5 PRO 8645HS vs Intel Core 5 223PE Comparison

Head-to-Head Benchmarks

The recorded benchmark data is unambiguous: the Intel Core 5 223PE wins every single head-to-head comparison against the AMD Ryzen 5 PRO 8645HS, 17 wins to 0. This is a sweeping result, but the margins vary widely by workload, and the data reveals where the Intel part is merely ahead versus where it is dominant.

The closest contest is PassMark random string sorting, where the Intel Core 5 223PE scores 35,798 against the AMD Ryzen 5 PRO 8645HS's 35,472, a narrow 0.9% advantage. This near-tie indicates that this specific workload, which stresses memory access patterns and branch handling, does not exaggerate the underlying performance gap. Similarly, PassMark data encryption shows a modest 5.8% lead for Intel (18,448 vs. 17,387), and single-threaded PassMark tests show an 8.6% edge (4,219 vs. 3,858). These are the smallest deltas in the entire dataset, suggesting that the AMD part is comparatively competitive in lightly threaded, latency-sensitive tasks.

The Cinebench suite tells a consistent story: across R15, R20, and R23, both multi-core and single-core, the Intel chip leads by a nearly identical margin of 25.4% or 25.5%. For example, Cinebench R23 multi-core shows Intel at 26,455 versus AMD's 19,742, a delta of 25.4%. Single-core R23 shows Intel at 3,734 versus 2,787, also 25.4%. This uniformity across all six Cinebench tests indicates a stable per-clock advantage, not a workload-specific anomaly.

The largest gaps emerge in integer and floating-point math. PassMark floating point math shows Intel at 76,468 versus 45,481, a massive 40.5% lead. PassMark physics is even more lopsided at 51.5% (2,493 vs. 1,208). PassMark find prime numbers shows the single biggest relative deficit for AMD: 159 versus 73, a 54.1% gap. These results confirm that the Intel processor delivers substantially higher compute throughput in mathematically intensive workloads.

Intermediate deltas appear in PassMark integer math (27.1% ahead for Intel, 99,819 vs. 72,740), multi-thread (24.3%, 31,124 vs. 23,569), and data compression (23.3%, 346,623 vs. 265,826). Extended instructions show a 14% advantage for Intel (24,672 vs. 21,212). Overall, the average benchmark score places the Intel part at 40,585 versus 30,879 for AMD, a 31.4% aggregate gap, and the Intel chip sits in the 87th percentile of all CPUs versus the 82nd for AMD.

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS has zero benchmark wins in the recorded data, so no workload category favors it. The Intel Core 5 223PE wins across all 17 recorded tests, but the magnitude of its advantage defines distinct use-case tiers.

For general productivity and mixed workloads, the Intel advantage is moderate. Single-threaded PassMark (8.6% ahead) and random string sorting (0.9% ahead) show that the Intel part does not crush the AMD chip in every scenario. In these tasks, the delta is small enough that real-world differences could be subtle.

For content creation and rendering, the Cinebench results at 25.4% ahead indicate a clear, consistent performance tier. A 25% margin in both single-core and multi-core rendering means the Intel processor will complete Cinebench-style renders noticeably faster, but the AMD chip is not out of its class.

For scientific computing, financial modeling, physics simulation, and heavy mathematical workloads, the Intel lead is decisive. Floating point math at 40.5% ahead, physics at 51.5% ahead, and prime number finding at 54.1% ahead show that the Intel architecture has a substantial throughput advantage in raw compute. These are the workloads where the choice is least ambiguous.

For data compression and encryption, the Intel part leads by 23.3% and 5.8% respectively. Compression work benefits significantly from the Intel chip, while encryption tasks are closer, making the AMD part a more viable option in that narrow niche.

Architecture Differences

The two processors come from fundamentally different design philosophies and manufacturing processes. The AMD Ryzen 5 PRO 8645HS uses Zen 4 architecture on a 4 nm TSMC process, codenamed Hawk Point, and belongs to the 8000 series. The Intel Core 5 223PE uses Bartlett Lake on Intel's 10 nm process, with no specific architecture name listed in the database.

Core count and thread count differ meaningfully: the AMD part has 6 cores and 12 threads, while the Intel part has 8 cores and 16 threads. This two-core, four-thread advantage partially explains the multi-threaded performance gap, but the single-core differences show Intel also has a per-core edge.

Clock speeds tell a nuanced story. The AMD chip has a higher base clock at 4.30 GHz versus 2.90 GHz for Intel, but Intel has a higher boost clock at 5.20 GHz versus 5.00 GHz for AMD. The lower base clock for Intel is offset by a higher boost ceiling, and the benchmark data shows Intel wins in single-threaded tests despite the lower base frequency.

Cache hierarchies differ substantially. AMD provides 64 KB L1 per core, 1 MB L2 per core, and 16 MB shared L3. Intel provides 80 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3. Intel has more cache at every level, which contributes to its performance in cache-sensitive workloads like data compression and random string sorting.

Process node and foundry also differ: AMD uses TSMC at 4 nm with 25,000 million transistors on a 178 mm² die, while Intel uses its own foundry at 10 nm with no transistor or die size data recorded. The AMD die is physically smaller and more densely packed, but the Intel design uses a larger process node.

Memory support differs: AMD supports only DDR5, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical 89.6 GB/s bandwidth. Both support ECC memory.

PCIe capabilities are notably different. AMD provides PCIe Gen 4 with 20 lanes (CPU only), while Intel provides PCIe Gen 5 with 16 lanes (CPU only). The Intel part has a faster PCIe generation but fewer lanes.

Integrated graphics differ: AMD uses Radeon 760M, while Intel uses UHD Graphics 730. Socket types are not interchangeable: AMD uses AMD Socket FP7, while Intel uses Intel Socket 1700. The AMD part is a mobile segment chip released in April 2024, while the Intel part is a desktop segment chip released in March 2026. Both are currently Active in production, and both have locked multipliers.

The Verdict

The data directs a clear choice: the Intel Core 5 223PE outperforms the AMD Ryzen 5 PRO 8645HS in every recorded benchmark, with an average benchmark score of 40,585 versus 30,879. The Intel part also ranks higher overall, at the 87th percentile of all CPUs versus the 82nd for AMD.

The AMD Ryzen 5 PRO 8645HS is the appropriate pick only in scenarios where its specific physical attributes matter more than raw performance. It consumes less power (45 W TDP versus 65 W), uses a more advanced 4 nm process, and targets the mobile segment. Its integrated Radeon 760M graphics and smaller die size may suit compact mobile systems, and its support for only DDR5 simplifies memory design. But in pure compute terms, the database shows no workload where the AMD chip is superior.

The Intel Core 5 223PE is the stronger performer across the board, with particular dominance in floating-point math (40.5% ahead), physics simulation (51.5% ahead), and prime number finding (54.1% ahead). It also supports both DDR4 and DDR5 memory, offers PCIe Gen 5, and provides more cache at every level. Its higher TDP of 65 W and desktop market segment indicate it is designed for systems where power draw is less constrained.

For users prioritizing maximum compute throughput in rendering, mathematics, compression, or general multi-threaded work, the recorded data supports the Intel Core 5 223PE without qualification. The AMD part only becomes relevant when its mobile form factor, lower TDP, or specific platform requirements take precedence over benchmark scores. The 17-to-0 win count is decisive, and the aggregate 31.4% average score gap confirms that the Intel processor is in a different performance class.
