AMD Ryzen 9 7940HX vs Intel Core 5 223PE Comparison

The Verdict

The data splits this matchup cleanly by workload type. The AMD Ryzen 9 7940HX wins 9 of the 13 recorded head-to-head benchmarks, and it does so by massive margins in heavily threaded and compute-intensive tests. Its Cinebench R23 multicore score of 29,400 beats the Intel Core 5 223PE's 26,455 by 11.1%. In PassMark integer math, the AMD chip scores 202,883 versus 99,819, a 103.3% advantage. The Ryzen 9 7940HX is the clear choice for rendering, encoding, scientific computing, and any workload that scales across cores.

The Intel Core 5 223PE, however, wins the four benchmarks where per-thread efficiency matters more than raw core count. Its Cinebench R23 single-core score of 3,734 crushes the AMD part's 1,807 by 51.6%. PassMark single-thread performance also favors Intel at 4,219 versus 3,942, a 6.6% edge. The Intel chip wins PassMark physics as well, 2,493 to 2,297. For applications that are lightly threaded or latency-sensitive, the Core 5 223PE delivers noticeably better responsiveness per core.

The overall database ranking reflects the AMD part's dominance. The Ryzen 9 7940HX sits at the 94th percentile among all CPUs with an average benchmark score of 69,875, while the Core 5 223PE ranks at the 87th percentile with an average of 40,585. That 72.2% gap in average score summarizes the story: the AMD processor is in a different performance class for multi-threaded work, while the Intel processor offers superior single-thread performance but far fewer cores to draw upon.

Architecture Differences

The two processors come from opposite ends of the design spectrum. The AMD Ryzen 9 7940HX uses Zen 4 architecture on a 5 nm process from TSMC, packing 16 cores and 32 threads into a Dragon Range mobile package. The Intel Core 5 223PE uses Bartlett Lake architecture on Intel's 10 nm process, with 8 cores and 16 threads. That 2x core and thread advantage for AMD explains most of the multi-threaded benchmark gap.

Cache configurations differ substantially. AMD allocates 64 KB of L1 cache per core and 1 MB of L2 per core, with a large 64 MB L3 cache shared across the chip. Intel provides 80 KB of L1 per core and 2 MB of L2 per core, but only 24 MB of shared L3. The larger AMD L3 pool helps when working sets exceed Intel's 24 MB capacity, which shows up in the data compression and random string sorting tests.

Memory support also diverges. The AMD chip supports DDR5 only, with dual-channel memory and 83.2 GB/s of bandwidth. The Intel part supports both DDR4 and DDR5, also dual-channel, with a slightly higher rated bandwidth of 89.6 GB/s. Intel also supports ECC memory, which the AMD part does not. For workstation or server-adjacent uses, that ECC support could be decisive despite the AMD part's compute advantages.

The platform envelopes differ as well. AMD uses Socket FL1 with a 55 W TDP, while Intel uses Socket 1700 with a 65 W TDP. AMD's PCIe implementation offers Gen 5 with 28 lanes from the CPU, versus Intel's Gen 5 with 16 lanes. Both have integrated graphics: AMD's Radeon 610M versus Intel's UHD Graphics 730. The AMD chip has an unlocked multiplier; the Intel part is locked. AMD's 13,140 million transistors spread across two 71 mm² die segments, while Intel's transistor count and die size are not recorded in the database.

Head-to-Head Benchmarks

The largest wins for the AMD Ryzen 9 7940HX come in data-heavy and encryption workloads. PassMark random string sorting shows AMD at 81,775 versus Intel's 35,798, a 128.4% lead. Data encryption follows closely: AMD scores 41,974 against Intel's 18,448, a 127.5% margin. Extended instructions also swing heavily toward AMD, 51,029 versus 24,672, a 106.8% difference. These are workloads where the 16-core AMD design can spread work across many parallel threads.

PassMark integer math doubles Intel's result: 202,883 versus 99,819, a 103.3% gap. Data compression shows a 100.1% advantage for AMD at 693,741 versus 346,623. Floating point math favors AMD by 58.7%, with scores of 121,383 against 76,468. Prime number finding gives AMD a 71.7% edge, 273 versus 159. PassMark multithread shows AMD at 53,204 versus 31,124, a 70.9% lead. The Cinebench R23 multicore result, while the smallest multi-thread win at 11.1%, still confirms the pattern in a widely recognized rendering benchmark.

Intel's wins are concentrated in single-thread performance and one physics test. The Cinebench R23 single-core result is the most striking: Intel's 3,734 more than doubles AMD's 1,807, a 51.6% advantage. PassMark single-thread gives Intel a 6.6% edge at 4,219 versus 3,942. PassMark physics shows Intel winning 2,493 to 2,297, a 7.9% margin. These results indicate the Intel core design extracts more work per clock cycle, but the AMD chip compensates with sheer core count.

Where Each One Wins

The AMD Ryzen 9 7940HX dominates every heavily parallel workload in the recorded data. Its 100.1% lead in data compression and 128.4% lead in random string sorting make it the stronger choice for file archiving, database operations, and text processing pipelines. The 127.5% encryption advantage points to faster disk encryption and secure communication workloads. Integer and floating point math leads of 103.3% and 58.7% respectively position the AMD chip for scientific simulations, financial modeling, and engineering analysis. The 70.9% multithread advantage and 11.1% Cinebench R23 multicore win cover rendering and video encoding. Anyone running multi-threaded productivity software, virtual machines, or content creation tools gets substantially more throughput from the AMD part.

The Intel Core 5 223PE wins where single-thread latency matters most. Its 51.6% Cinebench R23 single-core advantage and 6.6% PassMark single-thread lead make it the better fit for applications that rely on a single fast core: legacy software, certain database queries with serial dependencies, and interactive workloads where response time per action is critical. The 7.9% PassMark physics win suggests better performance in physics simulation that does not scale well across many cores. The Intel chip also consumes a 65 W TDP versus AMD's 55 W, but the recorded data does not include efficiency metrics, so any power comparison must remain qualitative.

The average score gap of 72.2% in favor of AMD underscores that the Ryzen 9 7940HX is the higher-performing processor overall. The Intel Core 5 223PE's wins are real but narrow in aggregate impact. Its single-thread lead is dramatic in percentage terms, yet the AMD chip's multi-thread wins are consistently in the 58% to 128% range across seven different PassMark subtests. For users whose workloads can parallelize, the AMD part delivers multiples of Intel's performance. For users locked into single-threaded applications, the Intel part delivers meaningfully faster per-core results, but the overall performance ceiling is far lower.
