AMD Ryzen AI 5 435 vs Intel Core 7 251E Comparison

The AMD Ryzen AI 5 435 and the Intel Core 7 251E occupy different design philosophies entirely. The AMD part is a mobile-first processor built on a dense manufacturing node with a focus on efficiency, while the Intel part is a desktop processor with a much higher core count and a more traditional power envelope. The recorded data shows that these processors are not direct competitors in the same segment, but comparing them reveals the trade-offs between a high-core-count desktop design and a compact mobile design. The benchmarks available for the AMD part allow for a detailed analysis of its strengths, while the Intel part’s specifications and lack of benchmark scores define its position in the database.

Where Each One Wins

The AMD Ryzen AI 5 435 wins decisively in the single-core and multi-core benchmarks recorded in the database. It posts a Cinebench R23 multi-core score of 11333 and a single-core score of 1816. The Intel Core 7 251E has no recorded benchmark scores in the database, meaning all measured performance wins belong to the AMD part. However, the Intel part wins on raw specifications that matter for specific workloads: it has 24 cores and 32 threads versus the AMD’s 6 cores and 12 threads. This suggests the Intel part would be better suited for heavily parallelized tasks that scale with core count, such as video rendering or software compilation, though no measured data confirms this.

The AMD part also wins on efficiency-oriented features. It has a 28 W TDP, while the Intel part has a 65 W TDP. The AMD part uses a 4 nm process from TSMC, while the Intel part uses a 10 nm process from Intel. The AMD part is listed as a mobile processor, while the Intel part is a desktop processor. Therefore, the AMD part wins in scenarios requiring low power consumption and portability, while the Intel part wins in scenarios requiring maximum core throughput.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen AI 5 435 uses a 4 nm process from TSMC, while the Intel Core 7 251E uses a 10 nm process from Intel. The AMD part’s architecture is Zen 5, with a codename of Gorgon Point, and it belongs to the Ryzen AI 400 generation, which includes both Zen 5 and Zen 5c cores. The Intel part’s architecture is not listed, but its codename is Bartlett Lake, and it belongs to the Core 7 generation.

The core layouts differ substantially. The AMD part has 6 cores and 12 threads. The Intel part has 24 cores and 32 threads. This means the Intel part has four times the core count and nearly three times the thread count. Cache configurations also differ. The AMD part has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 4 MB of L3 cache total. The Intel part has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of L3 cache shared. The Intel part’s L3 cache is nine times larger than the AMD part’s.

The integrated graphics differ. The AMD part uses Radeon 840M, while the Intel part uses UHD Graphics 770. Memory support overlaps on DDR5, but the AMD part also supports LPDDR5X, while the Intel part also supports DDR4. Both support ECC memory. The sockets are incompatible: AMD Socket FP8 for the AMD part and Intel Socket 1700 for the Intel part.

The process node difference is significant. A 4 nm process versus a 10 nm process indicates that the AMD part uses a much denser transistor design, which typically allows for lower power consumption at the same performance level. The Intel part’s larger process node suggests it relies on brute-force core count rather than transistor density to achieve performance.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen AI 5 435 and the Intel Core 7 251E. The Intel part has an empty benchmark array, and its average benchmark score is 0. The AMD part has a complete set of benchmark scores. Therefore, every measured comparison in this analysis is based on the AMD part’s absolute scores and its position relative to other CPUs in the database.

The AMD Ryzen AI 5 435 achieves an average benchmark score of 28128. Its percentile versus all CPUs is 80, meaning it outperforms 80 percent of all processors in the database. Its nearest rivals are the Intel Core i5-13490F with an average score of 28185, which is 0.2 percent higher, and the Intel Core i5-14500T with an average score of 28065, which is 0.2 percent lower. These rivals are close in performance, indicating the AMD part sits in a competitive mid-range tier.

In Cinebench R15, the AMD part scores 1686 in multi-core and 260 in single-core. In Cinebench R23, it scores 11333 in multi-core and 1816 in single-core. These scores indicate strong performance for a 28 W mobile processor. The Passmark suite shows a multi-thread score of 19000 and a single-thread score of 3734. Specific Passmark workloads include data compression at 225374, data encryption at 11110, extended instructions at 16197, find prime numbers at 58, floating point math at 40627, integer math at 61026, physics at 1075, and random string sorting at 24891.

The Intel Core 7 251E has no scores to compare. The recorded data only provides its specifications and a 50th percentile ranking, which reflects its position without benchmark data. Its average benchmark score of 0 confirms that no measured performance exists in the database.

The Verdict

The data indicates a clear split based on use case. The AMD Ryzen AI 5 435 is the only one of the two with measured performance, and it delivers strong results for a mobile processor. Its 28 W TDP, 4 nm process, and 80th percentile ranking show that it achieves competitive performance while consuming less than half the power of the Intel part. Its Cinebench R23 multi-core score of 11333 and Passmark multi-thread score of 19000 are solid figures for a processor in its class. The AMD part is the choice for thin-and-light laptops or any system where power draw and heat output are the primary constraints.

The Intel Core 7 251E offers raw core count and clock speed advantages. Its 24 cores and 32 threads, combined with a boost clock of 5.60 GHz and a 36 MB L3 cache, suggest it is designed for desktop workloads that can use all available threads. Its 65 W TDP and 10 nm process indicate a less efficient design, but the larger cache and higher core count may benefit tasks like database processing, code compilation, or 3D rendering. The Intel part has no benchmark scores, so its actual measured performance is unknown, but its specifications place it in the desktop market segment.

The decision comes down to platform and workload. A mobile user with a need for efficiency and portability should select the AMD Ryzen AI 5 435, as its benchmark data confirms capable performance at a 28 W TDP. A desktop user with a workload that scales across many cores should consider the Intel Core 7 251E, based on its 24-core configuration and higher boost clock, but should note that no measured performance data exists in the database to validate its real-world speed. The AMD part is the proven performer in this comparison, while the Intel part is an unverified specification sheet.
