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

Head-to-Head Benchmarks

The benchmark data splits this comparison into two distinct profiles. The AMD Ryzen 7 8840HX takes 8 of the 13 recorded head-to-head tests, while the Intel Core 5 223PE wins 5. The margins, however, tell the real story.

The Intel Core 5 223PE delivers its most decisive victory in the Cinebench R23 single-core test. It scores 3734 against the AMD's 1857, a 50.3% advantage. That is a massive gap for a single-threaded workload, and it reflects the Intel part's higher 5.20 GHz boost clock against the AMD's 5.10 GHz. The Intel chip also wins the PassMark single-thread test, 4219 to 3958, a 6.2% edge. In Cinebench R23 multi-core, the Intel part scores 26455 against 25265, a 4.5% lead, despite having 4 fewer cores and 8 fewer threads. The Intel CPU also takes the PassMark physics test, 2493 to 2185, a 12.4% margin.

The AMD Ryzen 7 8840HX answers with substantial wins across most other workloads. Its largest margin comes in PassMark find prime numbers, where it scores 304 against Intel's 159, a 91.2% advantage. Data encryption shows a 62.2% lead (29919 vs 18448), and random string sorting is 61.9% higher (57971 vs 35798). The AMD part also leads in extended instructions by 48.1% (36527 vs 24672), integer math by 46.8% (146506 vs 99819), and data compression by 43.2% (496427 vs 346623). Floating point math is closer but still favors AMD, 86747 to 76468, a 13.4% margin. The PassMark multi-thread score goes to AMD at 41732 versus 31124, a 34.1% difference.

The average benchmark scores reinforce the split. The AMD Ryzen 7 8840HX posts an average score of 71797, placing it in the 94th percentile of all CPUs. Its nearest rival, the Intel Core Ultra 7 265KF, scores 71910, a 0.2% difference, meaning the AMD chip sits within a rounding error of that competitor. The Intel Core 5 223PE averages 40585, good for the 87th percentile. Its closest rival, the Intel Core 7 253PE, scores 40557, a 0.1% gap.

What the scores show is a processor that wins on raw thread throughput and vector-style workloads (AMD) facing a processor that wins on per-core speed and lightly threaded tasks (Intel). The single-core Cinebench result is especially telling: a 50.3% deficit means the AMD chip cannot compete in applications that depend on one or two fast cores.

Where Each One Wins

The AMD Ryzen 7 8840HX is the stronger choice for workloads that scale across many threads or that hammer integer and encryption pipelines. Its 12 cores and 24 threads give it a structural advantage in multi-threaded throughput, which shows in the 34.1% PassMark multi-thread lead. Data compression, integer math, extended instructions, and encryption are all areas where the AMD chip leads by margins between 43.2% and 62.2%. Prime number finding, a heavily integer-bound test, shows the largest gap at 91.2%. Floating point math is also in AMD's favor, though the 13.4% margin is smaller than the other wins. For database compression, file archiving, code compilation, or any workload that uses many threads and integer operations, the data points to the AMD processor.

The Intel Core 5 223PE is the pick for single-threaded responsiveness and lightly threaded applications. The 50.3% Cinebench R23 single-core lead is the headline, but the PassMark single-thread win of 6.2% also matters. The physics test result (2493 vs 2185, a 12.4% win) suggests games or physics simulations that favor a few fast cores will run better on the Intel part. The Intel chip also manages to beat the AMD part in Cinebench R23 multi-core despite having 4 fewer cores and 8 fewer threads, which indicates its per-core efficiency carries over even into multi-threaded rendering. The 4.5% margin there is modest, but it flips the expected outcome given the core count difference.

Looking at the rival data, the AMD Ryzen 7 8840HX sits near the Intel Core Ultra 7 265KF (0.2% lower average score) and above the Intel Xeon 6724P by 0.8%. Those are higher-tier desktop and server parts, and the AMD chip's placement among them confirms its multi-threaded standing. The Intel Core 5 223PE, by contrast, sits near the Intel Core 7 253PE (0.1% higher) and the AMD Ryzen AI 5 PRO 435G (0.3% higher), a lower performance tier overall.

Specification Differences

The core and thread counts differ sharply. The AMD Ryzen 7 8840HX has 12 cores and 24 threads; the Intel Core 5 223PE has 8 cores and 16 threads. Both share a 2.90 GHz base clock, but the Intel part boosts to 5.20 GHz versus 5.10 GHz for the AMD chip. Thermal design power differs as well: the AMD part is rated at 55 W, the Intel part at 65 W.

Memory support separates the two clearly. The AMD chip supports DDR5 only, dual-channel, with a memory bandwidth of 83.2 GB/s. The Intel chip supports both DDR4 and DDR5, dual-channel, with a memory bandwidth of 89.6 GB/s. The Intel part also supports ECC memory, while the AMD part does not. That ECC support is a meaningful differentiator for error-sensitive computing environments.

PCIe lane counts differ. The AMD Ryzen 7 8840HX provides Gen 5 with 28 lanes (CPU only). The Intel Core 5 223PE provides Gen 5 with 16 lanes (CPU only). The AMD part offers 12 more lanes, which matters for systems with multiple high-bandwidth devices.

The sockets are incompatible: AMD uses Socket FL1, while Intel uses Socket 1700. The AMD part has an unlocked multiplier; the Intel part is locked. Integrated graphics differ, with the Radeon 610M in the AMD chip and UHD Graphics 730 in the Intel chip. The AMD processor is marked as a mobile segment part, while the Intel processor is marked as a desktop segment part. The Intel Core 5 223PE has a launch MSRP of $232; the AMD Ryzen 7 8840HX has no recorded launch MSRP.

Architecture Differences

The AMD Ryzen 7 8840HX uses the Zen 4 architecture, codenamed Dragon Range, and belongs to the 8000 series as a Ryzen 7 generation part. It is built on a 5 nm process at TSMC, with 13,140 million transistors and a die size of 2x 71 mm². The Intel Core 5 223PE uses the Bartlett Lake codename and is a Core 5 generation part, built on a 10 nm process at Intel. No transistor count or die size is recorded for the Intel chip.

Cache layouts differ substantially. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The AMD part's 64 MB L3 is 2.67 times larger than the Intel part's 24 MB, which helps explain its strong performance in data compression and repeated-access workloads. The Intel part has larger per-core L1 and L2 caches, which supports its single-thread strength.

The process node difference is notable: 5 nm (TSMC) for AMD versus 10 nm (Intel) for the Intel chip. The AMD part's smaller node likely contributes to its lower 55 W TDP despite having 50% more cores. The Intel part's higher 65 W TDP and larger process node suggest a different design priority, favoring higher clocks over efficiency.

The Verdict

The data supports a clear split based on workload type. The AMD Ryzen 7 8840HX should be chosen when multi-threaded throughput and integer-heavy tasks dominate. Its 34.1% lead in PassMark multi-thread, 43.2% lead in data compression, 46.8% lead in integer math, and 91.2% lead in prime number finding make it the stronger processor for encoding, compression, encryption, and parallel compute. Its 94th percentile ranking and average score of 71797 place it near the Intel Core Ultra 7 265KF, a much higher-tier part. The 64 MB L3 cache and 28 PCIe Gen 5 lanes add further weight for data-heavy configurations.

The Intel Core 5 223PE should be chosen when single-thread performance and per-core speed matter most. The 50.3% Cinebench R23 single-core advantage is the largest single-thread gap in this comparison, and the 6.2% PassMark single-thread win confirms it. The physics test win of 12.4% and the 4.5% multi-core Cinebench win despite fewer cores show that the Intel part punches above its core count in lightly threaded and mixed workloads. Its support for ECC memory and DDR4 compatibility widens its applicability in specific system builds.

For a mobile or compact system where the 55 W TDP, 12 cores, and 24 threads of the AMD part fit, the Ryzen 7 8840HX is the data-backed choice. For a desktop build where single-thread speed, ECC memory, and a locked multiplier with a known $232 launch MSRP matter, the Intel Core 5 223PE is the better fit. Neither processor dominates the other across the full benchmark suite; the selection depends entirely on whether the workload favors many threads or fast individual cores.
