AMD Ryzen 7 PRO 8840U vs Intel Core 5 223PE Comparison

The AMD Ryzen 7 PRO 8840U and the Intel Core 5 223PE are both 8-core, 16-thread processors, but they target different market segments and deliver distinctly different performance profiles. The recorded data shows a clear overall winner in raw compute: the Intel Core 5 223PE wins all 17 head-to-head benchmark comparisons, with an average benchmark score of 40585 compared to the AMD part's 32233. The Intel chip also sits at the 87th percentile of all CPUs, while the AMD chip sits at the 83rd percentile. This creates an interesting dynamic: the AMD processor is a mobile part designed for efficiency, while the Intel processor is a desktop part with a higher power envelope. The data indicates that the Intel chip is consistently faster, but the AMD chip's architectural efficiency and mobile positioning make it the appropriate choice for a different class of machine.

Where Each One Wins

The head-to-head data is one-sided. The Intel Core 5 223PE wins every single recorded benchmark, from Cinebench rendering tests to PassMark's specialty workloads. The margin varies significantly depending on the workload type. In Cinebench R23 multicore, the Intel part scores 26455 against the AMD part's 20254, a 23.4% deficit for the AMD chip. The same 23.4% gap appears in Cinebench R15 and R20 multicore tests, indicating a consistent multithreaded performance advantage for the Intel chip across all three Cinebench versions.

Single-core performance shows a similar pattern. The Intel chip scores 3734 in Cinebench R23 single-core, while the AMD chip scores 2859, again a 23.4% difference. In Cinebench R20 single-core, the Intel chip scores 1568 versus 1200 for the AMD chip, a 23.5% gap. This consistency suggests the Intel part has a fundamental clock speed and IPC advantage in this comparison.

The largest margins appear in specific PassMark tests. The Intel chip wins PassMark physics by 52.9%, scoring 2493 versus 1174. It also wins PassMark find prime numbers by 52.2%, scoring 159 versus 76. These are the two most dramatic wins for the Intel chip. Floating point math shows a 33.6% Intel advantage, with scores of 76468 versus 50746. The narrowest gap is in random string sorting, where the Intel chip leads by only 7.5%, scoring 35798 versus 33109. Data encryption shows a 10.9% Intel lead, and integer math shows an 11.5% Intel lead.

The AMD Ryzen 7 PRO 8840U wins no benchmarks in this comparison. Its role is not defined by winning performance tests but by its mobile efficiency characteristics. The AMD chip uses a 28 W TDP, while the Intel chip uses a 65 W TDP. The AMD chip belongs to the 8000 series and uses the Hawk Point codename with Zen 4 architecture, while the Intel chip uses Bartlett Lake. The AMD chip is listed as a Mobile market segment part, while the Intel chip is listed as Desktop.

Architecture Differences

The two processors come from different manufacturing backgrounds. The AMD Ryzen 7 PRO 8840U uses a 4 nm process node fabricated by TSMC, with 25,000 million transistors on a 178 mm² die. The Intel Core 5 223PE uses a 10 nm process node fabricated by Intel, with no transistor count or die size recorded in the database. This process difference is substantial: the AMD chip packs more transistors into a smaller area using a more advanced node.

Cache configurations differ. The AMD chip uses 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Intel chip uses 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. The Intel part has more cache at every level, which likely contributes to its performance advantage in cache-sensitive workloads.

Memory support differs. The AMD chip supports DDR5 only, while the Intel chip supports both DDR4 and DDR5. Both use dual-channel memory buses with 89.6 GB/s of memory bandwidth. Both support ECC memory. The PCIe configurations differ: the AMD chip uses Gen 4 with 20 lanes from the CPU, while the Intel chip uses Gen 5 with 16 lanes from the CPU. The Intel part offers a newer PCIe generation but fewer lanes.

Integrated graphics differ. The AMD chip uses Radeon 780M, while the Intel chip uses UHD Graphics 730. The AMD mobile chip's Radeon 780M is part of its Hawk Point design, while the Intel desktop chip's UHD Graphics 730 serves basic display output. The sockets differ as well: the AMD chip uses AMD Socket FP7, while the Intel chip uses Intel Socket 1700. The AMD chip has two part numbers recorded (100-000001317 for FP7r2 and 100-000001377 for FP7), while the Intel chip has one (SA4QF).

Clock speeds show a trade-off. The AMD chip has a 3.30 GHz base clock and a 5.10 GHz boost clock. The Intel chip has a 2.90 GHz base clock and a 5.20 GHz boost clock. The Intel chip boosts higher but starts lower. The Intel chip's higher boost clock, combined with its larger cache and higher TDP, appears to drive its benchmark advantage.

The Verdict

The data directs each processor to a different buyer. The Intel Core 5 223PE is the clear performance winner in this comparison, winning all 17 recorded benchmarks. Its 65 W TDP and Desktop market segment make it suitable for desktop systems where power consumption is less critical. The Intel chip's 5.20 GHz boost clock, 24 MB L3 cache, and support for both DDR4 and DDR5 memory give it flexibility and speed. Its average benchmark score of 40585 places it at the 87th percentile of all CPUs, and its nearest rivals include the Intel Core 7 253PE and AMD Ryzen AI 5 PRO 435G, indicating it competes in a higher performance tier.

The AMD Ryzen 7 PRO 8840U serves a different purpose. Its 28 W TDP and Mobile market segment indicate it is designed for laptops and portable devices where power efficiency matters more than raw performance. The AMD chip's 4 nm TSMC process and 25,000 million transistors on a 178 mm² die show a more advanced manufacturing approach. Its Radeon 780M integrated graphics likely provide better iGPU performance than the Intel chip's UHD Graphics 730, though no graphics benchmarks appear in the recorded data.

The performance gaps are substantial but not uniform. The Intel chip's 52.9% lead in physics and 52.2% lead in prime number finding suggest workloads involving heavy mathematical computation will strongly favor the Intel part. The smaller 7.5% gap in random string sorting and 10.9% gap in encryption suggest memory-intensive or cryptographic workloads narrow the distance. The consistent 23.4% Cinebench gaps indicate rendering workloads will reliably favor the Intel chip.

The choice depends on the use case. Desktop users building a system around Socket 1700 and seeking maximum compute performance should select the Intel Core 5 223PE. Mobile users or those building power-constrained systems around AMD Socket FP7 should select the AMD Ryzen 7 PRO 8840U, accepting its performance deficit in exchange for the lower 28 W TDP. The recorded data offers no scenario where the AMD chip wins a performance benchmark, but its mobile positioning and efficiency characteristics define its role. The Intel chip's launch MSRP is $232. The AMD chip has no recorded launch MSRP.
