Architecture Differences

The AMD Ryzen AI 5 340 uses the Zen 5 architecture under the Krackan Point codename, built on a 4 nm TSMC process. It integrates 6 cores and 12 threads. The die measures 195 mm². Each core carries 80 KB of L1 cache and 1 MB of L2 cache, with 8 MB of shared L3 cache. The processor supports DDR5 and LPDDR5X memory through a dual-channel bus, achieving 89.6 GB/s of memory bandwidth. It includes Radeon 840M integrated graphics and connects via PCIe Gen 4 with 16 CPU lanes. The socket is AMD Socket FP8, and the TDP is 28 watts. ECC memory is not supported.

The Intel Core 7 251TE uses the Bartlett Lake codename, built on a 10 nm Intel process. It packs 24 cores and 32 threads. The die measures 215 mm². Each core has 80 KB of L1 cache and 1.25 MB of L2 cache, with a much larger 36 MB shared L3 cache. Memory support includes both DDR4 and DDR5 through a dual-channel bus, with the same 89.6 GB/s bandwidth figure. The integrated graphics are UHD Graphics 770. PCIe connectivity is Gen 5 with 16 CPU lanes. The socket is Intel Socket 1700, and the TDP is 45 watts. ECC memory is supported, a feature absent on the AMD side.

The core count difference is the most significant architectural split: 6 cores versus 24 cores. The Intel part also has 12 more threads (32 versus 12). The L3 cache difference is substantial: 36 MB shared versus 8 MB. Process node favors AMD at 4 nm versus 10 nm, but the Intel processor compensates with a higher boost clock of 5.40 GHz versus 4.80 GHz for AMD.

Head-to-Head Benchmarks

The Intel Core 7 251TE dominates the Cinebench suite. In Cinebench R15 multi-core, Intel scores 2572 against AMD's 1915, a 25.5% margin. The single-core R15 test shows Intel at 362 versus 242.6, a 33% lead. Cinebench R23 multi-core delivers the largest gap in the entire comparison: Intel scores 25518, AMD scores 12532, making Intel 50.9% faster. The R23 single-core result follows the same pattern: 3602 versus 1915.5, a 46.8% advantage for Intel.

PassMark results reinforce the multi-core story. In floating-point math, Intel leads by 53.3% (85607 versus 39967). Integer math shows Intel at 125739 versus 63078, a 49.8% margin. Data encryption favors Intel by 48.3% (22176 versus 11470), while prime number finding shows Intel at 140 versus 72, a 48.6% gap. Multi-threaded PassMark scores put Intel at 30022 against AMD's 19506, a 35% lead. Physics tests show Intel at 1938 versus 1095, a 43.5% advantage. Data compression favors Intel by 31.3% (334399 versus 229796). Random string sorting goes Intel's way by 37% (39643 versus 24970). Extended instructions show the narrowest Intel victory: 16974 versus 16440, a 3.1% margin.

The AMD Ryzen AI 5 340 wins exactly one unique benchmark category. In PassMark single-thread, AMD scores 3683 against Intel's 3568, a 3.2% edge. This result appears twice in the data (as both passmark_single_thread and passmark_singlethread). No other test favors AMD.

Where Each One Wins

The Intel Core 7 251TE wins in every multi-threaded workload category recorded. Cinebench R15 and R23 multi-core tests show Intel leads ranging from 25.5% to 50.9%. PassMark multithread shows a 35% advantage. Floating-point math, integer math, data encryption, prime number finding, physics, data compression, and random string sorting all favor Intel by margins between 31.3% and 53.3%. The extended instructions test, while still an Intel win, is close at 3.1%. For rendering, scientific computation, encryption, compression, and any workload that scales across many cores, the data clearly favors the Intel Core 7 251TE.

The AMD Ryzen AI 5 340 wins the single-thread PassMark test by 3.2%. This indicates a modest advantage in lightly threaded applications that rely on one core's peak performance. The AMD part also carries a lower TDP (28 watts versus 45 watts) and a smaller die (195 mm² versus 215 mm²), which suggests lower power draw per unit of work, though the database does not include power efficiency measurements beyond TDP ratings. For mobile platforms where thermal limits are tight, the AMD part's lower TDP and 4 nm process node make it a relevant option. However, the benchmark results show that in raw performance, the Intel part wins 13 of 15 tests. The only scenario where the AMD processor delivers a higher score is the PassMark single-thread benchmark.
