Architecture Differences

The AMD Ryzen 9 8945HX belongs to the 8000 series and uses the Zen 4 architecture under the Dragon Range codename. It is manufactured on a 5 nm process at TSMC, with a transistor count of 13,140 million and a die size of 2x 71 mm². The chip is built for the AMD Socket FL1 and features an unlocked multiplier, allowing overclocking. Its integrated graphics are the Radeon 610M. The processor supports PCIe Gen 5 with 28 lanes from the CPU. Memory support is limited to DDR5 with a dual-channel bus, delivering a memory bandwidth of 83.2 GB/s. The L1 cache is 64 KB per core, L2 is 1 MB per core, and L3 totals 64 MB. The release date is recorded as 2025-04-22.

The Intel Core 5 223PTE uses the Bartlett Lake codename, with the generation labeled Core 5 (Bartlett Lake). It is fabricated on a 10 nm process at Intel. The socket is Intel Socket 1700. The multiplier is locked, so overclocking is not available. Integrated graphics are UHD Graphics 770. PCIe support is Gen 5 with 16 lanes from the CPU. Memory support includes both DDR4 and DDR5, with a dual-channel bus and a memory bandwidth of 89.6 GB/s. The L1 cache is 80 KB per core, L2 is 2 MB per core, and L3 is 24 MB shared. ECC memory is supported. The release date is recorded as 2026-03-08.

The architectural split is clear. AMD uses a unified Zen 4 design with 16 full-size cores, while Intel's Bartlett Lake part is a desktop processor with 8 cores and a more conventional cache hierarchy. The AMD chip carries a larger L3 pool at 64 MB versus 24 MB, and its per-core L1 and L2 are smaller at 64 KB and 1 MB compared to Intel's 80 KB and 2 MB per core. The AMD processor is also a mobile part on Socket FL1, whereas the Intel processor is a desktop part on Socket 1700. Process technology differs significantly, with AMD on 5 nm TSMC and Intel on 10 nm Intel. The AMD chip has more PCIe lanes at 28 versus 16, while the Intel chip supports ECC and older DDR4 memory.

Head-to-Head Benchmarks

The benchmark database contains extensive results for the AMD Ryzen 9 8945HX, but the Intel Core 5 223PTE has no recorded benchmark scores in the database. The Intel part shows an empty benchmarks array, an average benchmark score of zero, and a percentile of 50. Therefore, direct head-to-head comparisons rely on the AMD chip's measured results and the Intel chip's absence of data.

The AMD Ryzen 9 8945HX produces a Cinebench R15 multicore score of 4305 and a single-core score of 607. In Cinebench R20, the multicore result is 17939 and single-core is 2532. Cinebench R23 shows a multicore score of 42713 and a single-core score of 6030. These numbers place the AMD chip in the 95th percentile among all CPUs in the database, with an average benchmark score of 76212.

PassMark results for the AMD chip show a multithread score of 51405 and a single-thread score of 3907. The integer math score is 195180, floating point math is 117453, and find prime numbers is 262. Data compression scores 677755, data encryption scores 40836, and extended instructions score 49823. Physics scores 2168, and random string sorting scores 78781.

Because the Intel Core 5 223PTE has no benchmark entries, the database cannot establish a measured performance delta between the two processors. The only comparison available is the percentile field, where the AMD chip sits at 95 and the Intel chip at 50. That gap indicates a substantial difference in expected performance relative to the broader CPU population, but without Intel scores, no exact percentage or score differential can be stated.

The nearest rivals for the AMD Ryzen 9 8945HX provide context for its performance. The Intel Core Ultra 9 285HX has an average score of 76155, which is 0.1% lower than the AMD chip's 76212. The AMD EPYC Embedded 8224P scores 76492, which is 0.4% higher. The AMD Ryzen Threadripper PRO 9945WX scores 76513, also 0.4% higher. The AMD Ryzen 9 9950X3D scores 75779, which is 0.6% lower. These deltas show the Ryzen 9 8945HX sits within a tight performance cluster, effectively tied with the Intel Core Ultra 9 285HX and slightly behind the two EPYC and Threadripper parts, while edging out the Ryzen 9 9950X3D.

The Intel Core 5 223PTE has no nearest rivals listed, which reinforces the absence of measured data. The database records zero wins for both processors in head-to-head benchmarks, since no head-to-head benchmark entries exist.

The Verdict

The data in the database presents a clear picture for users choosing between these two processors. The AMD Ryzen 9 8945HX delivers a full set of measured benchmark results, including a Cinebench R23 multicore score of 42713 and a single-core score of 6030. Its average benchmark score of 76212 places it in the 95th percentile among all CPUs. The Intel Core 5 223PTE has no benchmark scores recorded, an average score of zero, and a 50th percentile ranking. From the recorded data alone, the AMD processor demonstrates a substantial performance advantage, but that conclusion is based on the absence of Intel measurements rather than a direct comparison.

For workloads that rely on multi-threaded performance, the AMD Ryzen 9 8945HX offers 16 cores and 32 threads, double the Intel part's 8 cores and 16 threads. The AMD chip also carries 64 MB of L3 cache versus 24 MB on Intel, which typically benefits large working sets and parallel tasks. The mobile segment designation and 55 watt TDP indicate the AMD processor is designed for high-end laptops, while the Intel Core 5 223PTE is a desktop processor with a 45 watt TDP and ECC memory support.

The Intel Core 5 223PTE holds advantages in specific areas. It supports ECC memory, which matters for reliability-sensitive desktop builds. It also supports DDR4 alongside DDR5, giving platform flexibility. Its memory bandwidth is higher at 89.6 GB/s compared to 83.2 GB/s on AMD. The Intel chip has a locked multiplier, but it also has a lower TDP and a launch MSRP of $232, which can be stated once as recorded.

Users on the mobile side should consider the AMD Ryzen 9 8945HX, as it is the only mobile part in this comparison with measured performance data. Users building a desktop system with ECC requirements would look to the Intel Core 5 223PTE, since the AMD chip does not support ECC. The Intel part also offers a choice between DDR4 and DDR5 memory, while the AMD chip is restricted to DDR5.

The database shows the AMD Ryzen 9 8945HX sits within 0.6% of four high-end rivals, including the Intel Core Ultra 9 285HX and AMD Ryzen 9 9950X3D. That clustering confirms the AMD chip performs at the top tier of the database. The Intel Core 5 223PTE has no such context, which leaves its performance unmeasured and unranked relative to peers.

In short, the data supports the AMD Ryzen 9 8945HX for users who need measured multi-core and single-core performance in a mobile package, and the Intel Core 5 223PTE for desktop users who need ECC support and DDR4 compatibility. Without benchmark results for the Intel part, no direct performance verdict can be issued, but the specification differences point to distinct use cases.
