AMD Ryzen AI 5 340 vs Intel Core 7 253PE Comparison

The AMD Ryzen AI 5 340 and Intel Core 7 253PE occupy different tiers of the database’s performance rankings. The Intel part holds a clear advantage across every recorded benchmark, with the AMD chip trailing in all 15 head-to-head tests. The data indicates that the Intel Core 7 253PE is the stronger processor for multi-threaded workloads, single-threaded tasks, and memory-intensive operations alike. The AMD Ryzen AI 5 340, by contrast, offers a lower power envelope and a more compact platform, but its benchmark scores place it firmly behind Intel’s offering in raw compute output.

The Verdict

The benchmark data leaves no ambiguity about which processor delivers higher performance. The Intel Core 7 253PE wins every single head-to-head comparison, with deltas ranging from a narrow 6.9% in single-threaded tests to a dominant 50.6% in floating-point math. The AMD Ryzen AI 5 340 does not record a single win in the database’s head-to-head set. For users prioritizing maximum throughput in rendering, encryption, or mathematical workloads, the Intel Core 7 253PE is the only choice supported by the measurements.

The AMD processor’s role is defined by its platform characteristics rather than its benchmark scores. It uses a 28W TDP, an AMD Socket FP8, and integrated Radeon 840M graphics, positioning it as a mobile-oriented part. The Intel Core 7 253PE is a desktop processor with a 65W TDP, Intel Socket 1700, and UHD Graphics 730. The database shows the Intel chip achieving an 87th percentile ranking across all CPUs, while the AMD chip sits at the 78th percentile. The average benchmark score of the Intel part is 40557, against 25981 for the AMD part, a substantial gap that reflects the near-total performance dominance of the Intel chip.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen AI 5 340 uses the Zen 5 architecture under the Krackan Point codename, part of the Ryzen AI 300 generation that combines Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process by TSMC. The Intel Core 7 253PE is based on the Bartlett Lake codename, belonging to the Core 7 generation, and uses Intel’s own 10 nm process node. These process differences partly explain the divergent power and thermal profiles: the AMD chip’s 4 nm node allows a 28W TDP, while Intel’s 10 nm node supports a 65W TDP.

Core and thread counts differ sharply. The AMD part provides 6 cores and 12 threads, while the Intel part provides 10 cores and 20 threads. Cache hierarchies also diverge. Both share an 80 KB L1 cache per core, but the AMD chip has 1 MB of L2 per core and 8 MB of L3, whereas the Intel chip has 2 MB of L2 per core and a much larger 33 MB of shared L3. The larger cache pool on the Intel side likely contributes to its lead in multi-threaded tests that benefit from data reuse.

Memory support is another distinguishing factor. The AMD processor supports DDR5 and LPDDR5X memory, while the Intel processor supports both DDR4 and DDR5. Both use a dual-channel memory bus and report the same 89.6 GB/s memory bandwidth. The Intel chip adds ECC memory support, which the AMD chip lacks. PCIe connectivity also differs: the AMD part uses Gen 4 with 16 lanes (CPU only), while the Intel part uses Gen 5 with 16 lanes (CPU only). The integrated graphics units are different as well, with the AMD chip featuring Radeon 840M and the Intel chip featuring UHD Graphics 730.

Head-to-Head Benchmarks

The Intel Core 7 253PE dominates every recorded benchmark. In Cinebench R23 multicore, the Intel chip scores 24880 against AMD’s 12532, a delta of 49.6% in Intel’s favor. The same test in single-core shows Intel at 3512 versus AMD’s 1915.5, a 45.5% gap. Cinebench R15 results follow the pattern: Intel leads multicore with 2507 to 1915 (23.6% delta) and single-core with 354 to 242.6 (31.5% delta).

PassMark results reinforce the trend. In floating-point math, Intel scores 80870 versus AMD’s 39967, a 50.6% lead, the largest margin in the dataset. Integer math shows Intel at 114158 against 63078, a 44.7% difference. The find prime numbers test has Intel at 138 versus AMD’s 72, a 47.8% gap. Physics testing gives Intel 1845 against 1095, a 40.7% delta. Multithread results show Intel at 29271 against 19506, a 33.4% advantage.

The smallest margins appear in single-threaded and sorting tests. PassMark single-thread gives Intel 3955 against AMD’s 3683, a 6.9% delta. Random string sorting shows Intel at 32777 versus 24970, a 23.8% gap. Data compression has Intel at 339133 versus 229796, a 32.2% delta. Data encryption yields Intel 18385 against AMD’s 11470, a 37.6% difference. Extended instructions show Intel at 21806 against 16440, a 24.6% gap. The Intel processor wins all 15 head-to-head comparisons, with no wins recorded for the AMD part.

Where Each One Wins

The Intel Core 7 253PE wins in every measured category, so its advantages are comprehensive rather than niche. The largest leads come in compute-heavy tasks: floating-point math (50.6% ahead), Cinebench R23 multicore (49.6% ahead), and prime number finding (47.8% ahead). These results indicate strong performance for scientific, financial, or rendering workloads that rely on sustained multi-threaded execution. The Intel chip’s 10 cores, 20 threads, and 33 MB of shared L3 cache provide a structural advantage in such tasks.

The AMD Ryzen AI 5 340 does not win any benchmark, but its profile is not without utility. The 28W TDP suggests significantly lower power consumption, and the mobile-oriented Socket FP8 with LPDDR5X memory support points to compact, power-sensitive systems. The AMD part’s smaller margins in single-threaded tests (6.9% behind in PassMark single-thread) show that its per-core efficiency is closer to Intel’s than its multi-threaded scores imply. For workloads that are lightly threaded and power-constrained, the AMD chip’s deficit narrows, though it still trails in the recorded data.

The Intel processor’s ECC memory support and Gen 5 PCIe lanes make it suitable for desktop workstation scenarios where data integrity and high-bandwidth peripherals matter. The AMD processor’s integrated Radeon 840M graphics may offer different media or display capabilities, but the database does not include graphics benchmarks to quantify that. The recorded data consistently favors the Intel Core 7 253PE across every test, leaving the AMD Ryzen AI 5 340 as the lower-power alternative with a smaller performance footprint.
