AMD Ryzen AI 5 PRO 435G vs Intel Core Ultra 7 266V Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split between the AMD Ryzen AI 5 PRO 435G and the Intel Core Ultra 7 266V, with Intel taking 6 of the 11 head-to-head tests and AMD taking the remaining 5. The most dramatic gap appears in integer math, where AMD delivers a 53.3% advantage with a score of 63707 against Intel's 41558. This is the largest single-test margin in the entire comparison, suggesting a substantial efficiency or architecture advantage for AMD in this specific workload type.

Data compression follows a similar pattern, with AMD scoring 253484 versus Intel's 187050, a 35.5% lead. This reinforces the idea that AMD's design excels at throughput-oriented tasks involving large data volumes. Extended instructions favor AMD by 17.4%, with scores of 18697 and 15928 respectively, and random string sorting shows AMD ahead by 19.7% (27407 versus 22905).

Intel's wins are equally decisive in their own domains. The find prime numbers test shows Intel at 191 versus AMD's 55, a 71.2% advantage. This is the largest Intel lead and indicates a significant difference in how the two processors handle branch-heavy, integer-iteration workloads. Floating point math also favors Intel substantially, with 56923 versus 43494, a 23.6% margin. Physics simulation shows Intel ahead by 37.9% (1608 versus 999), and data encryption gives Intel a 12.4% edge (13822 versus 12111).

The multithread test is close: AMD scores 20285 against Intel's 19461, a 4.2% win. Single-thread performance is even tighter, with Intel taking it by just 2.9% (3943 versus 3829). These narrow margins suggest that in general-purpose processing, the two chips are nearly equivalent, with the larger deltas emerging only in specialized instruction patterns.

The average benchmark score tells a different story. AMD's average is 40718, while Intel's is 23297. This discrepancy arises because AMD's benchmark set includes the very high data compression score, which skews the average upward. The percentile rankings reflect the same pattern: AMD sits at the 87th percentile of all CPUs, while Intel sits at the 76th percentile. However, when comparing against their nearest rivals, both processors appear well-positioned: AMD's closest competitors are within 0.5% of its average score, and Intel's nearest rivals are within 0.6%.

Where Each One Wins

AMD's advantage concentrates in data-heavy, integer-oriented workloads. The 53.3% lead in integer math, the 35.5% lead in data compression, and the 19.7% lead in random string sorting all point toward a processor that handles large datasets and arithmetic-heavy loops efficiently. The extended instructions test, where AMD leads by 17.4%, suggests its instruction set implementation handles additional vector or specialized operations better. For database operations, file compression, or any workload that processes large blocks of structured data, the benchmark data clearly favors AMD.

Intel wins in scenarios that demand high single-thread responsiveness and specific mathematical operations. The 71.2% margin in prime number finding indicates superior handling of iterative, dependency-heavy computations. Floating point math, where Intel leads by 23.6%, matters for scientific computing, 3D rendering, and any application relying on fractional arithmetic. The physics test, which Intel wins by 37.9%, suggests better performance in simulation workloads that combine floating-point operations with branching logic. Data encryption, where Intel holds a 12.4% edge, could matter for security applications, VPN traffic, or encrypted storage.

The multithread score, while narrowly favoring AMD, indicates that both processors handle parallel workloads competently. The single-thread test, which Intel wins by 2.9%, shows that for everyday responsiveness, word processing, web browsing, or light coding, the two chips are nearly indistinguishable. The real differentiation emerges only when workloads push into the specific instruction patterns where one architecture has a clear structural advantage.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD's Ryzen AI 5 PRO 435G uses the Gorgon Point codename and belongs to the Ryzen AI PRO 400 generation based on Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC. Intel's Core Ultra 7 266V uses the Lunar Lake architecture, belongs to the Core Ultra Series 2, and is fabricated on a 3 nm process, also at TSMC. The 3 nm node gives Intel a potential transistor-density advantage, though the design choices differ significantly.

AMD's chip has 6 cores and 12 threads, leveraging simultaneous multithreading to extract more work from each core. Intel's chip has 8 cores and 8 threads, relying on a wider core count without multithreading. This partly explains why AMD wins the multithread test despite having fewer physical cores. AMD's cache structure uses 80 KB of L1 per core, 1 MB of L2 per core, and only 4 MB of L3. Intel allocates 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. Intel's larger L1 and L3 caches likely contribute to its single-thread performance edge and its strong showing in floating point and prime number tests.

Clock speeds also differ. AMD runs at a 2.00 GHz base and 4.50 GHz boost, while Intel runs at 2.20 GHz base and 5.00 GHz boost. Intel's higher boost clock aligns with its single-thread advantage. Power consumption is dramatically different: AMD's TDP is 65 watts, while Intel's is 17 watts. This suggests Intel achieves its performance at a fraction of the power draw, though the benchmark data does not include efficiency measurements.

Memory bandwidth favors Intel at 136.5 GB/s versus AMD's 89.6 GB/s, both using dual-channel configurations. AMD supports DDR5 and ECC memory, while Intel uses LPDDR5X and does not support ECC. PCIe connectivity also differs: AMD provides Gen 4 with 10 CPU lanes, while Intel provides Gen 5 with only 4 CPU lanes. The integrated graphics differ as well, with AMD using Radeon 840M and Intel using Arc 140V. AMD targets the desktop market with an AM5 socket, while Intel targets mobile with a BGA 2833 socket. AMD released in 2026, while Intel released in 2024.
