AMD Ryzen 5 PRO 8640HS vs Intel Core 5 223PE Comparison

The AMD Ryzen 5 PRO 8640HS and Intel Core 5 223PE occupy different corners of the processor market, and the benchmark data shows a clear performance hierarchy between them. The Intel Core 5 223PE wins all 17 recorded head-to-head comparisons, but the margin varies significantly depending on the workload. This analysis breaks down those results, the architectural reasons behind them, and what the data means for specific use cases.

Head-to-Head Benchmarks

The Intel Core 5 223PE establishes a dominant position across every recorded test. In Cinebench R23 multicore, the Intel part scores 26455 against 18104 for the AMD, a 31.6% advantage. Cinebench R23 singlecore shows a similar gap: 3734 versus 2555, again 31.6%. This consistent delta across both single and multi-threaded Cinebench tests indicates a fundamental performance advantage rather than a workload-specific quirk.

The PassMark suite reveals where the gap widens and narrows. The largest margin appears in PassMark physics, where Intel scores 2493 against AMD's 1043, a 58.2% difference. PassMark find prime numbers also shows a substantial gap at 55.3% (159 versus 71). These tests rely heavily on integer arithmetic and memory latency, areas where the Intel architecture appears to have a strong edge.

Floating point math shows a 43.7% difference, with Intel at 76468 and AMD at 43019. Data compression favors Intel by 28.9% (346623 versus 246446). Integer math shows a 30% gap (99819 versus 69839). Extended instructions deliver a 25% difference (24672 versus 18507).

The narrowest margins appear in random string sorting, where Intel leads by 15.5% (35798 versus 30235), and single-thread performance, where the gap is 15.6% (4219 versus 3561). Data encryption shows an 18.9% difference (18448 versus 14962). Multithread performance is 31% in Intel's favor (31124 versus 21465).

What these numbers indicate is that the Intel part wins everywhere, but the size of the win tells a story. For memory-latency-sensitive and physics-heavy workloads, Intel's advantage approaches 60%. For string manipulation and single-thread tasks, the advantage shrinks to roughly 15%. The AMD processor remains competitive in specific niches but cannot match the Intel part's overall throughput.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 PRO 8640HS uses Zen 4 architecture on a 4 nm TSMC process, code-named Hawk Point. It has 6 cores and 12 threads, with a base clock of 3.50 GHz and a boost clock of 4.90 GHz. The Intel Core 5 223PE, code-named Bartlett Lake, uses a 10 nm Intel process with 8 cores and 16 threads, running at 2.90 GHz base and 5.20 GHz boost.

Cache configurations differ substantially. AMD provides 64 KB L1 per core and 1 MB L2 per core, with 16 MB shared L3. Intel provides 80 KB L1 per core and 2 MB L2 per core, with a larger 24 MB shared L3. This larger cache hierarchy likely contributes to Intel's advantages in data compression and random string sorting.

Process node and transistor count tell a story of different priorities. AMD's 4 nm TSMC process packs 25,000 million transistors into a 178 mm² die. Intel's die size and transistor count are not recorded in the database, but the 10 nm process suggests a different density approach. The AMD part draws 28 W TDP, while Intel specifies 65 W. This power difference is significant: the Intel part consumes more than double the thermal envelope.

Memory support differs as well. AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with 89.6 GB/s bandwidth. Both support ECC memory. PCIe capabilities diverge: AMD offers Gen 4 with 20 lanes, while Intel offers Gen 5 with 16 lanes. Intel's PCIe 5.0 support provides higher per-lane bandwidth, though AMD provides more total lanes.

Integrated graphics differ: AMD uses Radeon 760M, Intel uses UHD Graphics 730. The market segments also differ, with AMD targeting mobile (Socket FP7) and Intel targeting desktop (Socket 1700). Release dates are recorded as April 2024 for AMD and March 2026 for Intel, making the Intel part a later release.

The Verdict

The recorded data indicates that the Intel Core 5 223PE is the faster processor in every measured category. Its 87th percentile ranking among all CPUs compares to 80th for the AMD part. The average benchmark score for Intel is 40585, versus 28478 for AMD, a difference of roughly 42%. The Intel part's nearest rivals include the Intel Core 7 253PE (0.1% higher), the Intel Xeon 6357P (0.1% lower), and the AMD Ryzen AI 5 PRO 435G (0.3% lower). The AMD part sits near the Intel Xeon E-2436 (0.2% lower), AMD Ryzen 7 PRO 6850HS (0.2% lower), and Intel Core 5 220H (0.3% lower).

The Intel part's 8 cores and 16 threads provide a structural advantage over AMD's 6 cores and 12 threads. Higher boost clock and larger L3 cache reinforce this. The 65 W TDP enables this performance but requires a desktop platform. The AMD part's 28 W TDP makes it suitable for mobile systems where thermal and power constraints are tighter.

The data suggests the Intel Core 5 223PE is the choice for workloads that need maximum throughput, particularly physics calculations, prime number finding, and floating point math. The AMD Ryzen 5 PRO 8640HS remains viable in mobile deployments where its lower power draw and smaller die size matter, and its 15.5% deficit in string sorting shows it handles certain data manipulation tasks relatively well. For desktop users prioritizing raw performance across all workloads, the Intel part's consistent 15% to 58% lead makes it the stronger option.
