AMD Ryzen 7 8840HX vs Intel Core 5 223PTE Comparison

The Verdict

The data places the AMD Ryzen 7 8840HX in a different performance class than the Intel Core 5 223PTE. With a 94th percentile ranking across all CPUs, the Ryzen 7 8840HX is positioned as a high-performance mobile processor, while the Intel Core 5 223PTE sits at the 50th percentile, indicating a mainstream desktop part. The AMD chip delivers a substantial core and thread advantage, 12 cores and 24 threads versus 8 cores and 16 threads, and its benchmark results confirm a wide gap in multi-threaded workloads. The Intel part counters with a higher boost clock, 5.40 GHz versus 5.10 GHz, and a larger per-core L2 cache, which could benefit single-threaded responsiveness, but the recorded data shows the AMD processor's average benchmark score of 71,797 dwarfs the Intel part's unmeasured score of 0. For users prioritizing raw throughput in rendering, encryption, or math-heavy tasks, the Ryzen 7 8840HX is the clear choice from the data. The Intel Core 5 223PTE, with its lower 45 W TDP and desktop socket, suits a more modest, power-conscious desktop build where the higher boost clock may help in lightly threaded tasks, though the lack of benchmark data for the Intel part limits direct comparison.

Architecture Differences

The two processors come from different design philosophies and market segments. The AMD Ryzen 7 8840HX uses the Zen 4 architecture on a 5 nm process fabricated by TSMC, with the Dragon Range codename. It is a mobile chip for AMD Socket FL1, packing 12 cores and 24 threads. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a large 64 MB shared L3 cache. The chip is built from a two-die design, with each die measuring 71 mm², totaling 13,140 million transistors. It supports dual-channel DDR5 memory with a bandwidth of 83.2 GB/s, and the integrated graphics are Radeon 610M. The PCIe interface is Gen 5 with 28 lanes from the CPU, and the multiplier is unlocked.

The Intel Core 5 223PTE is a desktop processor built on the Bartlett Lake codename, using a 10 nm process from Intel's own foundry. It has 8 cores and 16 threads, with a base clock of 2.30 GHz and a boost clock of 5.40 GHz. The cache layout differs: 80 KB of L1 per core and 2 MB of L2 per core, but only 24 MB of shared L3. This part supports both DDR4 and DDR5 memory in a dual-channel configuration, with a slightly higher memory bandwidth of 89.6 GB/s. It includes ECC memory support, a feature absent on the AMD side. The integrated graphics are UHD Graphics 770. The PCIe interface is Gen 5 but limited to 16 lanes from the CPU. The socket is Intel Socket 1700, and the multiplier is locked. The Intel chip has a lower TDP of 45 W versus the AMD's 55 W, and it carries a launch MSRP of $232.

Head-to-Head Benchmarks

Direct head-to-head benchmark results are not recorded in the database for these two specific chips. However, the AMD Ryzen 7 8840HX has a full suite of individual benchmark scores that illustrate its capabilities. In Cinebench R23, the multicore score is 25,265, and the single-core score is 1,857. These are strong numbers for a mobile processor, particularly the multicore result which reflects the 12-core configuration.

PassMark tests show a wide range of performance. The data compression score is 496,427, while data encryption reaches 29,919. Extended instructions score 36,527, and finding prime numbers returns 304. Floating point math scores 86,747, and integer math scores 146,506. The multithread score is 41,732, with physics at 2,185 and random string sorting at 57,971. Single-thread performance is recorded at 3,958.

The average benchmark score for the AMD part is 71,797, which places it in the 94th percentile of all CPUs. The nearest rivals in the database are all Intel server or desktop parts: the Intel Core Ultra 7 265KF with an average score of 71,910 and a delta of -0.2 percent, the Intel Xeon Platinum 8270 at 71,370 with a delta of 0.6 percent, the Intel Xeon 6517P at 72,350 with a delta of -0.8 percent, and the Intel Xeon 6724P at 72,396 with a delta of -0.8 percent. This means the Ryzen 7 8840HX is effectively on par with these much larger or higher-tier processors, trailing the Core Ultra 7 265KF by a mere 0.2 percent and actually beating the Xeon Platinum 8270 by 0.6 percent.

The Intel Core 5 223PTE has no recorded benchmark scores and no nearest rivals, so its average benchmark score is listed as 0. This absence of data makes a direct numerical comparison impossible. The only measurable advantage for the Intel part from the specification sheet is the higher boost clock of 5.40 GHz and the larger L2 cache per core, but without benchmark results, the database cannot quantify how those translate into real performance.

Where Each One Wins

The AMD Ryzen 7 8840HX wins decisively in multi-threaded and compute-heavy workloads. The Cinebench R23 multicore score of 25,265 and the PassMark multithread score of 41,732 reflect the advantage of 12 cores and 24 threads. The large 64 MB shared L3 cache and 5 nm process contribute to strong results in data compression (496,427), floating point math (86,747), and integer math (146,506). The encryption score of 29,919 and extended instructions score of 36,527 further indicate that security and vectorized workloads are handled with high efficiency. The chip's 94th percentile ranking and average score of 71,797 place it in the company of server-class Xeon parts, making it the clear winner for content creation, scientific computing, and any heavily parallel task.

The Intel Core 5 223PTE wins in specific niche areas based on its specifications, even without benchmark data. The higher boost clock of 5.40 GHz, combined with a larger 2 MB L2 cache per core, suggests a potential advantage in latency-sensitive, lightly threaded applications where single-core speed matters most. The lower TDP of 45 W versus 55 W makes it a more power-efficient choice for a desktop system, and the support for both DDR4 and DDR5 memory offers flexibility in platform choice. The inclusion of ECC memory support is a distinct advantage for reliability-focused workloads such as file servers or error-sensitive data processing. The Intel part also has a higher memory bandwidth of 89.6 GB/s, which could benefit memory-bound tasks. However, with no benchmark scores recorded, the database cannot confirm the magnitude of these advantages, and the Intel part's 50th percentile ranking suggests a much lower overall performance ceiling. For users with single-threaded, low-power, or ECC requirements, the Intel Core 5 223PTE is the logical pick; for everything else, the AMD Ryzen 7 8840HX dominates based on the recorded data.
