AMD Ryzen AI 5 340 vs Intel Core 7 251E Comparison

AMD Ryzen AI 5 340 vs Intel Core 7 251E

The AMD Ryzen AI 5 340 and Intel Core 7 251E occupy different positions in the desktop and mobile landscape, with the AMD part targeting low-power mobile systems and the Intel part serving as a high-core-count desktop processor. The recorded data shows a significant divergence in core counts, process technology, and platform features, while the benchmark database contains a full suite of results for the AMD processor and no recorded scores for the Intel part. This analysis relies on the available measurements to interpret the AMD Ryzen AI 5 340’s standing, and uses the specification differences to frame the comparison between the two.

Where Each One Wins

The AMD Ryzen AI 5 340 wins in any workload where the benchmark database has recorded results, since the Intel Core 7 251E has no benchmark scores in the database. The AMD processor’s 6 cores and 12 threads, built on the Zen 5 architecture, deliver a Cinebench R23 multi-core score of 12532, a Geekbench multi-core score of 9165, and a Passmark multithread score of 19506. These results place the Ryzen AI 5 340 in the 78th percentile of all CPUs, with an average benchmark score of 25981. The nearest rivals in the database, such as the Intel Core i7-14701TE at 26013 and the AMD Ryzen 5 8640HS at 26106, are within 0.5% of the Ryzen AI 5 340’s average score, indicating that this processor sits in a tightly contested performance band despite its modest 28 W TDP.

The Intel Core 7 251E wins on paper specifications that the database records, including core count, thread count, boost clock, cache capacity, and platform features. With 24 cores and 32 threads, a boost clock of 5.60 GHz, 36 MB of shared L3 cache, and support for PCIe Gen 5, the Intel part is positioned for heavy multi-threaded desktop workloads. The Intel processor also supports ECC memory and DDR4 memory, which the AMD part does not, giving it an advantage in reliability-focused and legacy-compatible configurations. The database shows no benchmark wins for either processor in head-to-head tests, as the head-to-head benchmark array is empty, so the only measurable wins belong to the AMD part through its recorded scores.

Head-to-Head Benchmarks

The head-to-head benchmark array in the database is empty, so there are no direct comparative scores between the AMD Ryzen AI 5 340 and the Intel Core 7 251E. The available measurements come entirely from the AMD processor’s benchmark suite. The Ryzen AI 5 340 records a Cinebench R23 multi-core score of 12532 and a single-core score of 1915.5. In Cinebench R15, it scores 1915 multi-core and 242.6 single-core. Geekbench results show 9165 multi-core and 2140 single-core.

The Passmark suite provides a broader view of the AMD processor’s capabilities. The data compression test scores 229796, data encryption scores 11470, and extended instructions score 16440. Integer math scores 63078, floating point math scores 39967, and find prime numbers scores 72. Random string sorting scores 24970, physics scores 1095, and single-thread performance is recorded at 3683 in both the passmark_single_thread and passmark_singlethread tests. The multithread score is 19506.

These numbers place the Ryzen AI 5 340 within 0.7% of its nearest rivals in either direction. The Intel Core i7-14701TE is 0.1% higher, the AMD Ryzen 5 8640HS is 0.5% higher, the AMD Ryzen 5 PRO 5655GE is 0.4% lower, and the Intel Core i7-11700K is 0.7% lower. The tight clustering of these average scores suggests that the Ryzen AI 5 340 delivers performance comparable to a range of desktop and high-performance mobile processors, despite its 28 W TDP and 6-core configuration. For the Intel Core 7 251E, no score exists to compare, so any performance inference must come from its specification sheet rather than measured data.

Specification Differences

The two processors differ across nearly every major specification field. The AMD Ryzen AI 5 340 has 6 cores and 12 threads, while the Intel Core 7 251E has 24 cores and 32 threads. Base clocks are close, with the AMD part at 2.00 GHz and the Intel part at 2.10 GHz, but boost clocks diverge sharply: the Ryzen AI 5 340 boosts to 4.80 GHz, while the Core 7 251E boosts to 5.60 GHz. The TDP also differs substantially, with the AMD part rated at 28 W and the Intel part at 65 W.

The cache hierarchy shows clear differences. Both processors use an 80 KB L1 cache per core, and the AMD part uses 1 MB L2 per core, while the Intel part uses 2 MB L2 per core. The L3 cache differs in both size and organization: the AMD Ryzen AI 5 340 has 8 MB of L3, while the Intel Core 7 251E has 36 MB of shared L3. Memory support diverges as well, with the AMD part supporting DDR5 and LPDDR5X, while the Intel part supports DDR4 and DDR5. Both have dual-channel memory buses and identical memory bandwidth of 89.6 GB/s, but ECC memory support is present only on the Intel processor.

PCIe support differs by generation and lane count. The AMD Ryzen AI 5 340 uses PCIe Gen 4 with 16 lanes from the CPU, while the Intel Core 7 251E uses PCIe Gen 5 with 16 lanes from the CPU. The integrated graphics also differ: the AMD part uses the Radeon 840M, while the Intel part uses UHD Graphics 770. The market segment is listed as Mobile for the AMD processor and Desktop for the Intel processor. The release dates are close, with the AMD part released on 2025-01-05 and the Intel part on 2025-01-12. The Intel Core 7 251E has a recorded launch MSRP of $384, while the AMD Ryzen AI 5 340 has no launch MSRP in the database. Both processors have locked multipliers.

Architecture Differences

The AMD Ryzen AI 5 340 uses the Zen 5 architecture under the codename Krackan Point, belonging to the Ryzen AI 300 generation, which includes both Zen 5 and Zen 5c cores. It is fabricated on a 4 nm process at TSMC, with a die size of 195 mm². The Intel Core 7 251E uses the Bartlett Lake codename under the Core 7 generation, fabricated on a 10 nm process at Intel, with a die size of 257 mm². The architecture field for the Intel part is null in the database, so no specific microarchitecture name is recorded beyond the codename.

The process node difference is significant: the AMD part uses a 4 nm process from TSMC, while the Intel part uses a 10 nm process from Intel. The die sizes reflect this, with the Intel chip being larger at 257 mm² compared to 195 mm² for the AMD chip. The core count difference is the most striking architectural gap, with the Intel part offering 24 cores and 32 threads against the AMD part’s 6 cores and 12 threads. The Intel part’s larger L2 cache per core, at 2 MB versus 1 MB, and its much larger shared L3 cache, at 36 MB versus 8 MB, point to a design aimed at sustained multi-threaded throughput.

The sockets differ entirely, with the AMD Ryzen AI 5 340 using AMD Socket FP8 and the Intel Core 7 251E using Intel Socket 1700. The AMD part is classified as a mobile processor, while the Intel part is classified as a desktop processor. The Intel part supports ECC memory and DDR4, which are absent from the AMD part, and it uses PCIe Gen 5 instead of Gen 4. The integrated graphics also reflect different design goals, with the Radeon 840M on the AMD side and UHD Graphics 770 on the Intel side. The production status for both is active, and both were released within a week of each other in January 2025.
