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

Head-to-Head Benchmarks

The benchmark data splits this pairing into two distinct personalities. Intel Core Ultra 7 266V takes the majority of wins, 9 out of 15 head-to-head tests, but AMD Ryzen AI 5 435 scores the most decisive victories. The largest margin belongs to AMD in integer math, where it posts 61026 against Intel's 41558, a 46.8% advantage. This is not a marginal difference; it is a dominant showing in a workload that reflects general arithmetic processing.

The Cinebench results tell a more complex story. In Cinebench R15 multicore, AMD edges ahead with 1686 versus 1667, a 1.1% lead. The single-core R15 test favors AMD more clearly, 260 to 235, a 10.6% gap. However, the newer Cinebench R23 tests reverse the outcome sharply. Intel delivers 16544 in multicore versus AMD's 11333, a 31.5% deficit for AMD. In R23 single-core, Intel leads 2335 to 1816, a 22.2% margin. The R15 and R23 versions measure different instruction mixes, and the data indicates Intel scales better under the R23 workload structure.

PassMark tests reveal further separation. AMD wins data compression by 20.5%, scoring 225374 against 187050. AMD also takes extended instructions, 16197 versus 15928, a 1.7% edge, and random string sorting, 24891 versus 22905, an 8.7% win. Intel counters in data encryption, 13822 versus 11110, a 19.6% lead. The prime number search is Intel's largest single win: 191 versus 58, a 69.6% advantage. Floating point math goes to Intel, 56923 versus 40627, a 28.6% margin. Intel also wins physics simulation, 1608 versus 1075, a 33.1% lead.

The aggregate metrics favor Intel narrowly. PassMark multithread shows 19461 for Intel versus 19000 for AMD, a 2.4% edge. Single-thread results give Intel 3943 versus 3734, a 5.3% lead. The overall average benchmark score places AMD at 28128 and Intel at 23297, but that figure is skewed by AMD's inclusion of additional benchmark entries. The percentile ranking against all CPUs puts AMD at 80 and Intel at 76. AMD's nearest rivals include Intel Core i5-13490F at 28185, a 0.2% delta, and Intel Core i5-14500T at 28065, a 0.2% delta. Intel's nearest rivals include AMD Ryzen 7 5800H at 23277, a 0.1% delta, and Intel Core Ultra 9 288V at 23219, a 0.3% delta.

Architecture Differences

The two processors come from different design philosophies. AMD Ryzen AI 5 435 uses Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI 400 generation that mixes Zen 5 and Zen 5c cores. Intel Core Ultra 7 266V uses Lunar Lake architecture, part of the Core Ultra Series 2. Both use TSMC manufacturing, but AMD is on a 4 nm node while Intel is on 3 nm.

Core counts differ structurally. AMD provides 6 cores and 12 threads, enabling simultaneous multithreading. Intel provides 8 cores and 8 threads, with no multithreading. The thread count parity, 12 versus 8, gives AMD more logical processors, yet Intel still wins most multithreaded benchmarks. This indicates Intel's per-core efficiency compensates for fewer threads.

Cache layouts diverge significantly. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of shared L3. Intel allocates 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. Intel's L3 is three times larger, which explains its strength in workloads that benefit from large shared caches, such as the prime number search and floating point math. AMD's smaller L3 still delivers wins in integer math and data compression, suggesting those workloads rely more on per-core cache and raw ALU throughput.

Memory bandwidth also favors Intel. AMD records 89.6 GB/s, while Intel reaches 136.5 GB/s, a 52.4% higher figure. Both support dual-channel memory, but Intel uses LPDDR5X with motherboard-dependent support, while AMD supports both DDR5 and LPDDR5X. AMD supports ECC memory; Intel does not. PCIe capabilities favor AMD with Gen 4 and 14 CPU lanes, while Intel offers Gen 5 but only 4 CPU lanes.

Integrated graphics differ as well. AMD uses Radeon 840M, Intel uses Arc 140V. The benchmark data does not include graphics tests, so the comparison must stay with CPU-focused results. Power envelopes are distinct: AMD has a 28 TDP, Intel a 17 TDP. Intel achieves higher benchmark scores despite a lower thermal budget, which points to the 3 nm node and the Lunar Lake efficiency design.

The Verdict

The data supports a clear split by workload type. Intel Core Ultra 7 266V is the stronger processor for sustained compute tasks, particularly those involving floating point, physics simulation, prime number generation, and the Cinebench R23 suite. Its 31.5% multicore R23 lead and 28.6% floating point lead are substantial. The 69.6% prime number advantage is the single largest margin in the entire comparison. For users running rendering, scientific calculations, or simulation workloads, Intel is the choice.

AMD Ryzen AI 5 435 wins where integer arithmetic and data manipulation dominate. The 46.8% integer math lead and 20.5% data compression lead are decisive. AMD also holds a 10.6% edge in Cinebench R15 single-core and a 1.1% lead in R15 multicore. For workloads such as database operations, compression pipelines, and general integer-heavy processing, AMD delivers better results.

The overall average benchmark scores place AMD at 28128, which is 20.7% higher than Intel's 23297, but this aggregate is not a reliable verdict because it includes AMD's Cinebench R15 results and Intel's R20 results without complete overlap. The head-to-head win count, 9 for Intel and 6 for AMD, favors Intel in breadth. However, AMD's wins are often larger in magnitude. The percentile ranking, 80 versus 76, places AMD slightly higher among all CPUs, but that metric includes the full benchmark set and does not isolate the head-to-head tests.

AMD offers more threads, ECC support, and more PCIe lanes. Intel offers a smaller process node, higher clocks, a lower TDP, more cache at every level, and substantially higher memory bandwidth. The release dates show AMD launched over a year later than Intel, yet its benchmark wins are concentrated in integer and data tasks rather than modern rendering workloads. The socket difference confirms these are not interchangeable platforms; motherboard selection must match the respective socket.
