The Verdict

The recorded data shows a clear division in intended use cases. The AMD Ryzen AI 7 350 is a mobile processor with an 84th percentile ranking among all CPUs, while the Intel Core 7 251E sits at the 50th percentile. However, the Intel chip has no benchmark scores recorded in the database, meaning direct performance comparisons rely entirely on the AMD side's measured results.

For mobile workloads where power efficiency matters, the AMD Ryzen AI 7 350 delivers substantial measured performance. Its 8-core, 16-thread configuration with a 28 TDP and 4 nm process node indicates a design focused on balancing compute with thermal constraints. The benchmark results, including a Cinebench R23 multicore score of 16014.5 and a Geekbench multicore score of 11676, place it in the 84th percentile of all CPUs.

The Intel Core 7 251E targets desktop systems with a 65 TDP and 24 cores. Its 5.60 GHz boost clock is the highest between the two, and its 36 MB shared L3 cache is more than four times larger than the AMD chip's 8 MB. The database shows no benchmark scores for this Intel processor, so its actual performance cannot be quantified from the available data.

The choice depends on platform requirements. The AMD Ryzen AI 7 350 suits mobile systems needing strong single-thread and multi-thread results within a 28 TDP envelope. The Intel Core 7 251E suits desktop builds that require ECC memory support, PCIe Gen 5 connectivity, and a higher core count, though its performance profile remains unmeasured in the database.

Head-to-Head Benchmarks

The head-to-head benchmark section in the database contains no direct comparison entries, and the win counts for both processors are zero. This means there are no matched test results where both chips ran identical workloads. The only measurable performance data belongs to the AMD Ryzen AI 7 350, which has a comprehensive set of 17 benchmark scores.

For the AMD chip, the Cinebench R15 multicore score is 2477, with a single-core score of 294. The newer Cinebench R23 test shows a multicore result of 16014.5 and a single-core result of 1958. Geekbench results follow a similar pattern: 11676 multicore and 2164 single-core.

PassMark results for the AMD processor cover a wide range of workloads. The multithread score is 24935, while single-thread performance registers at 3834. Integer math scores 85651, floating point math scores 53230, and extended instructions score 21678. Data compression reaches 304089, data encryption reaches 15244, and random string sorting hits 33266. Physics testing produces a score of 1349, and the find prime numbers test yields 80.

These numbers place the AMD Ryzen AI 7 350 in the 84th percentile of all CPUs. Its nearest rivals in the database include the AMD EPYC 4244P with an average score of 34220 and a delta percentage of 0, the AMD Ryzen 7 3700X with an average score of 34260 and a delta of -0.1 percent, the Intel Core i5-13450HX with an average score of 34333 and a delta of -0.3 percent, and the Intel Core Ultra 7 165H with an average score of 34083 and a delta of 0.4 percent.

The delta percentages show that the AMD Ryzen AI 7 350 sits within a narrow band of these rivals. It trails the Intel Core i5-13450HX by 0.3 percent, matches the AMD EPYC 4244P exactly, and leads the Intel Core Ultra 7 165H by 0.4 percent. This indicates that the chip's aggregate performance is comparable to a desktop EPYC processor, a previous-generation Ryzen 7, and a mobile Core Ultra 7, despite being a 28 TDP mobile part.

Because the Intel Core 7 251E has no recorded benchmarks, the head-to-head comparison cannot be completed numerically. The database shows zero wins for each processor, reflecting the absence of matched test data rather than a performance outcome.

Specification Differences

The two processors differ across nearly every major specification category. The AMD Ryzen AI 7 350 uses 8 cores and 16 threads, while the Intel Core 7 251E uses 24 cores and 32 threads. This gives the Intel chip three times the core count and double the thread count.

Clock speeds favor the Intel chip. The base clock is 2.10 GHz versus 2.00 GHz for the AMD part, and the boost clock is 5.60 GHz versus 5.00 GHz. Thermal design power also differs significantly: the Intel chip has a 65 TDP, while the AMD chip has a 28 TDP.

The socket and platform targets are entirely different. The AMD Ryzen AI 7 350 uses AMD Socket FP8, and the Intel Core 7 251E uses Intel Socket 1700. The AMD chip is classified as a mobile processor, while the Intel chip is a desktop processor.

Memory support shows a split. The AMD chip supports DDR5 and LPDDR5X, while the Intel chip supports DDR4 and DDR5. Both use dual-channel memory buses, and both list memory bandwidth at 89.6 GB/s. ECC memory is supported only on the Intel chip.

PCIe connectivity differs by generation. The AMD chip uses PCIe Gen 4 with 16 lanes (CPU only), while the Intel chip uses PCIe Gen 5 with 16 lanes (CPU only). This gives the Intel processor a newer interface standard.

Integrated graphics are also different. The AMD Ryzen AI 7 350 includes Radeon 860M graphics, while the Intel Core 7 251E includes UHD Graphics 770.

The release dates are close: the AMD chip was released on 2025-01-05, and the Intel chip was released on 2025-01-12. Neither processor has an unlocked multiplier. The Intel chip has a launch MSRP of $384, while the AMD chip has no recorded launch MSRP.

Architecture Differences

The architectural split between these processors is substantial. The AMD Ryzen AI 7 350 is built on the Zen 5 architecture with the Krackan Point codename, and it belongs to the Ryzen AI 300 generation that uses a hybrid of Zen 5 and Zen 5c cores. The Intel Core 7 251E uses the Bartlett Lake codename and belongs to the Core 7 generation.

The process nodes come from different foundries. AMD uses a 4 nm process at TSMC, while Intel uses a 10 nm process at its own foundry. The die sizes reflect this difference: the AMD chip measures 195 mm², and the Intel chip measures 257 mm².

Cache hierarchies follow different designs. Both chips use 80 KB of L1 cache per core, but the L2 cache differs: AMD uses 1 MB per core, while Intel uses 2 MB per core. The L3 cache shows the largest gap, with AMD providing 8 MB and Intel providing 36 MB shared across the chip.

The Intel Core 7 251E includes ECC memory support, a feature absent from the AMD Ryzen AI 7 350. The Intel chip also supports PCIe Gen 5, while the AMD chip is limited to PCIe Gen 4. The memory controller on the AMD chip accepts LPDDR5X in addition to DDR5, whereas the Intel chip accepts DDR4 in addition to DDR5.

The market segment separation is definitive: AMD targets mobile with a 28 TDP and FP8 socket, while Intel targets desktop with a 65 TDP and Socket 1700. The production status for both is listed as active, and neither has an unlocked multiplier.

The database records the AMD chip's part number as 100-000001601 and the Intel chip's as SRQDUQ657. The AMD processor carries a percentile ranking of 84 versus all CPUs, while the Intel processor carries a percentile ranking of 50. The average benchmark score for the AMD chip is 34222, while the Intel chip shows an average benchmark score of 0, reflecting its lack of recorded test data.
