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

Where Each One Wins

The benchmark data splits this comparison into two very different profiles. The Intel Core 7 251TE wins 13 of the 15 recorded head-to-head tests, while the AMD Ryzen AI 5 435 takes only 2. That lopsided tally, however, does not tell the whole story. The Intel part dominates in every multi-threaded and most single-threaded workloads, but the AMD chip claims the only outright single-thread victory in the PassMark suite.

Intel's wins are decisive in heavily parallel workloads. Cinebench R23 multi-core shows the largest gap: Intel scores 25518 against AMD's 11333, a 55.6% advantage. PassMark integer math follows a similar pattern, with Intel at 125739 versus 61026, a 51.5% lead. Floating point math also favors Intel heavily, 85607 to 40627, a 52.5% margin. Prime number finding is the widest gap of all, Intel at 140 versus AMD at 58, a 58.6% difference. Data encryption swings 49.9% toward Intel, 22176 to 11110.

The AMD Ryzen AI 5 435 wins both PassMark single-thread tests with identical scores of 3734 against Intel's 3568, a 4.7% margin. That is the only category where AMD shows an edge, and it is a narrow one. Every other benchmark, from Cinebench R15 single-core (Intel 362 vs AMD 260, a 28.2% lead) to Cinebench R23 single-core (Intel 3602 vs AMD 1816, a 49.6% lead), belongs to Intel.

The closest contest in the entire dataset is PassMark extended instructions, where Intel leads by just 4.6%, 16974 to 16197. That suggests the two architectures handle complex instruction streams on a more even footing than raw integer or floating point work. For users focused on heavily threaded rendering, encryption, compression, or physics simulation, the Intel part is the clear choice. For single-threaded PassMark workloads, the AMD chip holds a small but consistent advantage.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen AI 5 435 uses Zen 5 architecture on a 4 nm TSMC process, with the Gorgon Point codename and a Ryzen AI 400 generation label that combines Zen 5 and Zen 5c cores. It packs 6 cores and 12 threads, with a base clock of 2.00 GHz and a boost clock of 4.50 GHz. Its thermal envelope is 28 W TDP. The cache layout uses 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of L3. Memory support covers DDR5 and LPDDR5X over a dual-channel bus with 89.6 GB/s bandwidth. ECC memory is supported. The platform uses AMD Socket FP8 with PCIe Gen 4 and 14 CPU lanes. Integrated graphics come from the Radeon 840M. The part targets the mobile segment and its production status is active.

The Intel Core 7 251TE uses the Bartlett Lake codename on a 10 nm Intel process. It is a desktop part with 24 cores and 32 threads, a base clock of 1.40 GHz, and a boost clock of 5.40 GHz. Its TDP is 45 W. The cache hierarchy differs substantially: 80 KB of L1 per core, 1.25 MB of L2 per core, and 36 MB of shared L3. That is 9 times the L3 capacity of the AMD chip. Memory support includes DDR4 and DDR5 on a dual-channel bus with the same 89.6 GB/s bandwidth figure. ECC memory is also supported. The Intel part uses Socket 1700 with PCIe Gen 5 and 16 CPU lanes. Integrated graphics are UHD Graphics 770. The die area is listed at 215 mm².

The core count difference is the most consequential architectural gap. Intel offers 4 times the cores and roughly 2.7 times the threads of the AMD part. Even with a lower base clock, Intel's boost clock reaches 5.40 GHz versus AMD's 4.50 GHz. The process node difference, 4 nm versus 10 nm, gives AMD a fabrication advantage, but the Intel design compensates with a much larger core pool and bigger L3 cache. The PCIe generation gap, Gen 5 on Intel versus Gen 4 on AMD, plus the additional lanes, gives the Intel platform more headroom for expansion. Both parts support ECC and share identical memory bandwidth figures.

The Verdict

The data points to a straightforward conclusion: the Intel Core 7 251TE is the stronger processor in almost every measured workload. Its average benchmark score of 41650 places it in the 88th percentile of all CPUs, while the AMD Ryzen AI 5 435 averages 28128 and sits in the 80th percentile. The nearest rivals for Intel include the Intel Core Ultra 7 265H at 41621, the Intel Core i7-14650HX at 41576, the Intel Core i7-12850HX at 41779, and the Intel Core i7-14700T at 41914, with deltas ranging from 0.1% to -0.6%. AMD's nearest rivals include the Intel Core i5-13490F at 28185, the Intel Core i5-14500T at 28065, the AMD Ryzen 5 PRO 8500GE at 28054, and the AMD Ryzen 5 PRO 5655G at 28032, with deltas from -0.2% to 0.3%.

The Intel part's 88th percentile ranking versus AMD's 80th percentile confirms its overall performance tier. In Cinebench R23 multi-core, Intel leads by 55.6%, a margin that will dominate rendering and compilation workloads. In data compression, Intel leads by 32.6%, 334399 to 225374. In multithread PassMark, Intel leads by 36.7%, 30022 to 19000. Physics simulation favors Intel by 44.5%, 1938 to 1075. Random string sorting goes to Intel by 37.2%, 39643 to 24891. Every one of these workloads benefits from Intel's 24 cores, 32 threads, and 36 MB of L3.

The AMD part's only measurable advantage is the 4.7% PassMark single-thread win, 3734 to 3568. That is a real but modest edge. Users who prioritize single-threaded PassMark performance might prefer the AMD chip, but the Intel part wins Cinebench single-core tests by wide margins, 28.2% in R15 and 49.6% in R23. The PassMark single-thread result does not translate into Cinebench single-core superiority.

The Intel Core 7 251TE carries a launch MSRP of $384, which can be stated once as a reference point. The AMD part has no listed launch MSRP. The Intel part is a desktop processor with a 45 W TDP and Socket 1700, while the AMD part is a mobile processor with a 28 W TDP and Socket FP8. The Intel part's higher TDP and desktop positioning align with its performance results.

The AMD wins are both PassMark single-thread tests with identical scores: 3734 versus 3568, a 4.7% margin. The fact that AMD wins both the "single_thread" and "singlethread" entries with the same score and same delta confirms consistency in that particular metric.

The average benchmark scores reinforce the head-to-head results. Intel averages 41650 across its benchmark suite, while AMD averages 28128. Intel's nearest rival, the Intel Core Ultra 7 265H, sits just 0.1% behind at 41621, and the Intel Core i7-14650HX trails by 0.2% at 41576. AMD's closest rival is the Intel Core i5-13490F at 28185, a 0.2% gap in AMD's favor, followed by the Intel Core i5-14500T at 28065, a 0.2% advantage for AMD. These rival positions place both chips in competitive segments, but the absolute performance gap between the two reviewed parts is substantial.

The Cinebench R23 results are particularly telling. Intel's multi-core score of 25518 is more than double AMD's 11333. Intel's single-core score of 3602 also more than doubles AMD's 1816. The R15 results show the same pattern at smaller absolute values: Intel 2572 multi-core versus AMD 1686, and Intel 362 single-core versus AMD 260. Across every Cinebench test, Intel holds a lead between 28.2% and 55.6%. The PassMark data compression test, which measures a common productivity workload, gives Intel a 32.6% edge, 334399 to 225374.

The overall picture is one of Intel dominance across the board, with a single narrow AMD win in PassMark single-thread performance. The Intel Core 7 251TE delivers 13 wins, a higher percentile ranking, a larger core pool, more cache, and a higher boost clock. The AMD Ryzen AI 5 435 counters with a smaller process node, lower TDP, and a 4.7% PassMark single-thread advantage. For anyone choosing between these two on benchmark performance alone, the Intel part wins decisively.
