AMD Ryzen 9 8945HX vs Intel Core 5 223PE Comparison

Head-to-Head Benchmarks

The recorded data shows a dominant performance gap between these two processors. Across 17 benchmark comparisons, the AMD Ryzen 9 8945HX wins 14 tests while the Intel Core 5 223PE wins only 3. The average benchmark score difference is substantial: the AMD part scores 76,212 points on average versus 40,585 for the Intel part, placing the AMD processor in the 95th percentile of all CPUs while the Intel chip sits in the 87th percentile.

The largest win for the AMD Ryzen 9 8945HX comes in PassMark data encryption, where it scores 40,836 versus 18,448, a 121.4% advantage. Random string sorting shows a 120.1% gap (78,781 versus 35,798), and extended instructions run 101.9% faster (49,823 versus 24,672). Integer math nearly doubles the Intel result: 195,180 versus 99,819, a 95.5% delta. Data compression shows the same 95.5% gap with a score of 677,755 versus 346,623.

Cinebench results are consistent across every version. In R15 multi-core, the AMD chip scores 4,305 versus 2,666, a 61.5% lead. R15 single-core shows 607 versus 376, also 61.5% ahead. R20 multi-core delivers 17,939 versus 11,111, and R20 single-core lands at 2,532 versus 1,568. R23 multi-core reaches 42,713 versus 26,455, with single-core at 6,030 versus 3,734. Every Cinebench delta sits at exactly 61.5%, indicating a consistent architectural advantage rather than workload-specific behavior.

The Intel Core 5 223PE takes its wins in three specific areas. PassMark physics shows 2,493 versus 2,168, a 13% advantage for Intel. Single-thread performance in PassMark favors Intel at 4,219 versus 3,907, a 7.4% edge. The same single-thread result appears twice in the data set, confirming the margin. These wins are narrow compared to the AMD advantages, and they come in tests that measure specific execution paths rather than raw throughput.

Where Each One Wins

The AMD Ryzen 9 8945HX dominates every multi-threaded and compute-heavy workload in the database. Its Cinebench R23 multi-core score of 42,713 puts it far beyond the Intel part's 26,455, making it the clear choice for rendering, compilation, and any task that scales with cores and threads. The 16-core, 32-thread configuration gives it a structural advantage that shows in every parallel benchmark: multithread PassMark hits 51,405 versus 31,124, a 65.2% margin. Floating-point math runs at 117,453 versus 76,468, a 53.6% lead, which matters for scientific computing and simulation workloads.

Data-intensive tasks favor AMD heavily. The 95.5% gap in both data compression and integer math suggests the AMD part handles encryption, compression, and general arithmetic workloads with roughly double the throughput. The 121.4% encryption advantage makes it particularly well-suited for security-related processing, VPN termination, or database encryption tasks. The 101.9% extended instructions margin indicates better support for SIMD-style workloads, which benefits multimedia encoding and certain AI inference paths.

The Intel Core 5 223PE wins only in single-threaded PassMark and physics simulation. The 7.4% single-thread edge (4,219 versus 3,907) means it handles lightly-threaded legacy applications or single-thread-bound games with slightly better responsiveness. The 13% physics advantage (2,493 versus 2,168) suggests better performance in physics simulation workloads, which often rely on specific instruction patterns and cache behavior rather than raw core counts. These wins are real but narrow, and they do not offset the massive multi-threaded losses.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 9 8945HX uses Zen 4 architecture on a 5 nm process from TSMC, built from 13,140 million transistors across a 2x 71 mm² die configuration. It is codenamed Dragon Range and belongs to the 8000 series, targeting mobile systems with an AMD Socket FL1. The Intel Core 5 223PE uses Bartlett Lake architecture on Intel's 10 nm process, fits Socket 1700, and is a desktop part. Intel does not list transistor count or die size in the database.

Core counts differ sharply. AMD provides 16 cores and 32 threads, while Intel offers 8 cores and 16 threads. AMD's base clock is 2.50 GHz with a 5.40 GHz boost; Intel starts at 2.90 GHz and boosts to 5.20 GHz. The Intel chip has a higher base frequency, but the AMD part boosts higher. Thermal design power differs: AMD rates at 55 watts, Intel at 65 watts. The AMD chip has an unlocked multiplier, while the Intel part is locked.

Cache structures diverge significantly. AMD uses 64 KB L1 per core, 1 MB L2 per core, and 64 MB of shared L3. Intel uses 80 KB L1 per core, 2 MB L2 per core, and only 24 MB of shared L3. The AMD L3 pool is nearly three times larger, which helps keep more working data on-chip for multi-threaded workloads. Intel's larger per-core L1 and L2 may explain its single-thread PassMark advantage, as frequently accessed data stays closer to the execution units.

Memory support differs. AMD supports DDR5 only with dual-channel access and 83.2 GB/s bandwidth. Intel supports both DDR4 and DDR5 with dual-channel access and 89.6 GB/s bandwidth, giving it a slight memory bandwidth edge of 6.4 GB/s. Intel also supports ECC memory, while AMD does not. PCIe connectivity favors AMD: 28 Gen 5 lanes from the CPU versus 16 Gen 5 lanes from Intel, which matters for multiple GPUs or high-speed storage arrays.

Integrated graphics also differ. AMD includes Radeon 610M, while Intel ships UHD Graphics 730. The AMD part is marked as a mobile segment product with an April 2025 release date, while Intel's desktop part launched in March 2026. AMD's part number is 100-000001848, and Intel's is SA4QF. Intel lists a launch MSRP of $232; AMD has no listed launch MSRP.

The Verdict

The benchmark data makes the separation clear. The AMD Ryzen 9 8945HX wins 14 of 17 tests and holds a 87.8% higher average benchmark score (76,212 versus 40,585). Its 16 cores and 32 threads deliver 61.5% higher Cinebench scores across every version, and its PassMark advantages range from 53.6% to 121.4% depending on the workload. Anyone running multi-threaded rendering, data compression, encryption, or number-crunching tasks should pick the AMD part without hesitation.

The Intel Core 5 223PE wins only in single-thread PassMark and physics simulation. Its 7.4% single-thread edge and 13% physics advantage are real, but they come in narrow categories. The Intel chip also supports ECC memory and offers marginally higher memory bandwidth (89.6 GB/s versus 83.2 GB/s), which may matter for specific server or reliability-focused builds. Its desktop Socket 1700 and lower power ceiling of 65 watts make it easier to integrate into conventional desktop systems.

The data indicates the AMD Ryzen 9 8945HX is the stronger processor for nearly all compute-intensive applications. The Intel Core 5 223PE suits workloads that prioritize single-thread responsiveness, ECC support, or DDR4 compatibility. For mixed use, the AMD part's massive multi-threaded lead and higher boost clock (5.40 GHz versus 5.20 GHz) make it the more flexible choice. The Intel chip's higher base clock (2.90 GHz versus 2.50 GHz) does not translate into broader benchmark wins.
