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

Head-to-Head Benchmarks

The database contains a full benchmark profile for the AMD Ryzen 9 8945HX, while the Intel Core 5 223PQE currently has no recorded benchmark scores. This makes a direct statistical comparison impossible at this time. However, the available data for the AMD part can be analyzed on its own merits and against its nearest rivals.

The AMD Ryzen 9 8945HX posts an average benchmark score of 76,212 across all recorded tests. This places it in the 95th percentile of all CPUs in the database. Its nearest rival, the Intel Core Ultra 9 285HX, averages 76,155, a difference of only 0.1% in favor of the AMD chip. That margin is essentially a statistical tie. The AMD Ryzen 9 9950X3D scores 75,779, which is 0.6% behind the 8945HX. The AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX each score 76,492 and 76,513 respectively, putting them 0.4% ahead of the 8945HX. These deltas are all within a narrow band, indicating that the 8945HX performs at a level comparable to a range of high-end desktop and workstation processors.

Looking at specific workloads, the Cinebench results are instructive. In Cinebench R23 multi-core, the 8945HX scores 42,713. In single-core, it scores 6,030. The gap between these scores reflects the chip's strong parallel scaling. In Cinebench R20, the multi-core score is 17,939 and the single-core score is 2,532. Cinebench R15 shows 4,305 multi-core and 607 single-core. The ratios between multi-core and single-core scores are consistent across all three Cinebench versions, suggesting stable performance scaling as thread counts increase.

PassMark results break down performance into more specific operations. The multi-thread score is 51,405, while the single-thread score is 3,907. Integer math scores 195,180, which is substantially higher than floating point math at 117,453. Data compression scores 677,755, a very high figure compared to data encryption at 40,836. Extended instructions score 49,823. Random string sorting scores 78,781. Find prime numbers scores 262, and physics scores 2,168. These individual results show where the architecture excels: integer-heavy and compression workloads benefit greatly from the 16-core, 32-thread configuration.

Architecture Differences

The AMD Ryzen 9 8945HX and Intel Core 5 223PQE are built on fundamentally different platforms. The AMD part uses the Zen 4 architecture, specifically the Dragon Range codename, and is manufactured on a 5 nm process at TSMC. It contains 13,140 million transistors across a die size of 2x 71 mm². The Intel part uses the Bartlett Lake codename, built on a 10 nm process at Intel, with no transistor count or die size listed.

Core counts differ significantly. The AMD processor has 16 cores and 32 threads. The Intel processor has 8 cores and 16 threads. This is a 2x difference in both cores and threads. Clock speeds tell a different story. The AMD chip has a base clock of 2.50 GHz and a boost clock of 5.40 GHz. The Intel chip has a base clock of 4.00 GHz and a boost clock of 5.50 GHz. The Intel part has a higher base clock by 1.50 GHz, and a marginally higher boost clock by 0.10 GHz. However, the AMD chip has the advantage of more cores, which allows it to scale better in multi-threaded workloads.

Cache hierarchies also diverge. The AMD processor has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache. The Intel processor has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The AMD chip has more total L3 cache, but the Intel chip has a larger per-core L2 allocation. The total cache footprint favors AMD for data-heavy workloads.

Memory support differs as well. The AMD processor supports DDR5 only, with a dual-channel bus and 83.2 GB/s of memory bandwidth. The Intel processor supports both DDR4 and DDR5, also with a dual-channel bus, and has a higher memory bandwidth of 89.6 GB/s. The Intel part also supports ECC memory, while the AMD part does not.

PCIe connectivity is another point of separation. The AMD processor offers Gen 5 with 28 lanes (CPU only). The Intel processor offers Gen 5 with 16 lanes (CPU only). The AMD chip has nearly double the PCIe lane count, which matters for systems using multiple GPUs or high-speed NVMe storage.

Integrated graphics differ by vendor. The AMD chip uses a Radeon 610M, while the Intel chip uses UHD Graphics 770. The AMD processor has an unlocked multiplier, allowing overclocking. The Intel processor is locked. The AMD chip uses AMD Socket FL1 and targets the mobile market. The Intel chip uses Intel Socket 1700 and targets the desktop market. The AMD part was released on 2025-04-22, while the Intel part has a release date of 2026-03-08.

The Verdict

The data indicates that the AMD Ryzen 9 8945HX is a high-performance mobile processor, achieving a 95th percentile ranking among all CPUs. Its 16 cores and 32 threads give it a clear advantage in multi-threaded workloads, as evidenced by the Cinebench R23 multi-core score of 42,713. The Intel Core 5 223PQE, with no benchmark scores in the database, cannot be compared directly. Its specifications show a desktop processor with 8 cores and 16 threads, a higher base clock of 4.00 GHz, and support for both DDR4 and DDR5 memory.

From the recorded data, the AMD part is positioned alongside some of the strongest processors in the database, including the Intel Core Ultra 9 285HX and AMD Ryzen Threadripper PRO 9945WX. The delta percentages are all within 0.6%, meaning that the 8945HX is statistically indistinguishable from these rivals in average performance. The Intel Core 5 223PQE, given its lower core count and desktop orientation, would likely fall into a different performance tier, but the absence of benchmark data prevents any quantitative conclusion.

For users selecting a processor based strictly on recorded measurements, the AMD Ryzen 9 8945HX is the only one with verified performance data. The Intel Core 5 223PQE requires future benchmark entries before any comparison can be made.

Where Each One Wins

The AMD Ryzen 9 8945HX wins in multi-threaded performance based on its 16-core, 32-thread configuration. The Cinebench R23 multi-core score of 42,713 and the PassMark multi-thread score of 51,405 confirm this strength. The large 64 MB L3 cache and high PCIe lane count of 28 also favor this chip for workloads that require substantial data throughput and multiple expansion devices. The unlocked multiplier allows for performance tuning, which is a distinct advantage for users who want to adjust clock behavior.

The Intel Core 5 223PQE wins in certain specification categories, though without benchmark data these are theoretical rather than measured. Its base clock of 4.00 GHz is higher than the AMD chip's 2.50 GHz base clock, which could translate to better responsiveness in lightly threaded tasks. The boost clock of 5.50 GHz is also slightly higher than the AMD part's 5.40 GHz. The Intel processor supports both DDR4 and DDR5 memory, offering flexibility in platform choice, and its memory bandwidth of 89.6 GB/s exceeds the AMD chip's 83.2 GB/s. ECC memory support is a differentiator for the Intel part, making it suitable for error-sensitive computing environments. The Intel chip also has a larger per-core L2 cache of 2 MB compared to 1 MB on the AMD chip.

The AMD part is a mobile processor, so it wins in portability contexts. The Intel part is a desktop processor, so it wins in stationary desktop builds. The AMD chip's 55 W TDP is much lower than the Intel chip's 125 W TDP, indicating that the AMD part is more power-efficient. The Intel chip's higher TDP suggests it is designed for sustained heavy loads in a desktop chassis with more thermal headroom. The AMD part uses the Radeon 610M integrated graphics, while the Intel part uses UHD Graphics 770, so the Intel part likely has an advantage in integrated graphics capability, though no benchmark data confirms this.
