AMD Ryzen AI 5 430 vs Intel Core Ultra 7 266V Comparison

Head-to-Head Benchmarks

The head-to-head data presents a strikingly one-sided picture. The Intel Core Ultra 7 266V wins 14 of the 15 recorded comparisons, while the AMD Ryzen AI 5 430 takes a single victory. That lone AMD win comes in Cinebench R15 single-core, where the Ryzen AI 5 430 scores 269 against 235 for the Intel part, a 14.5% advantage. This is the only benchmark where AMD leads, and it is a narrow but clear one.

Every other comparison favors Intel, often by a substantial margin. The largest gap appears in Cinebench R23 multi-core, where Intel scores 16544 against AMD's 8130, a delta of -50.9% from AMD's perspective. This means the Intel processor delivers more than double the multi-threaded rendering score. Cinebench R15 multi-core shows a similar trend: Intel scores 1667 versus 1195, a 28.3% difference. The multi-core story is consistent, but the single-core results are more complex. In Cinebench R23 single-core, Intel wins with 2335 against 1797, a 23% gap, which reverses the R15 single-core result. The two Cinebench single-core tests disagree on the winner, which suggests the AMD part has an edge in the older workload while Intel dominates the newer one.

PassMark results reinforce the Intel advantage across most categories. Floating point math shows Intel at 56923 versus 27193, a 52.2% difference. Physics testing delivers a 54.9% gap, with Intel at 1608 and AMD at 726. Prime number finding is the most extreme: Intel scores 191, AMD scores 44, a 77% difference. Data encryption favors Intel at 13822 versus 7591, a 45.1% gap. Extended instructions show Intel at 15928 against 11455, a 28.1% difference. Data compression is closer but still clearly Intel's: 187050 versus 158912, a 15% gap. Random string sorting goes to Intel at 22905 versus 16623, a 27.4% difference.

The narrowest overall margin appears in integer math, where Intel scores 41558 and AMD scores 39637, a 4.6% gap. PassMark multi-thread shows Intel at 19461 versus 13320, a 31.6% difference. Single-thread PassMark results show Intel at 3943 versus 3683, a 6.6% gap, with both the single_thread and singlethread entries recording identical values. The average benchmark score for Intel is 23297, while AMD sits at 19617, a difference of 3680 points. Intel's percentile rating is 76 versus AMD's 73, placing both in the upper range of all CPUs tracked.

Where Each One Wins

The data splits cleanly by workload type. AMD's only win is in Cinebench R15 single-core, a legacy rendering test. This suggests the Ryzen AI 5 430 has a particular strength in older single-threaded instructions that does not carry over to newer tests. The Intel part wins the more modern Cinebench R23 single-core test by a solid 23%, so AMD's single-core advantage is not general, it is specific to one benchmark version.

Intel dominates in every multi-threaded workload recorded. Cinebench R15 and R23 multi-core both go to Intel, with the R23 gap exceeding 50%. PassMark multi-thread also favors Intel by 31.6%. The physics test, which often stresses complex floating-point calculations and thread scheduling, is firmly in Intel's hands at 54.9%. Floating point math, a broad measure of numerical throughput, shows Intel at more than double AMD's score.

Encryption and compression workloads also favor Intel. Data encryption shows a 45.1% gap, which indicates the Intel part handles cryptographic instructions much faster. Data compression, a memory and cache sensitive workload, gives Intel a 15% win. Random string sorting, another memory-heavy task, goes to Intel by 27.4%. Prime number finding, which is highly sensitive to branch prediction and integer throughput, is the most lopsided result at 77%. Extended instructions, covering SIMD and other specialized opcodes, favor Intel by 28.1%.

The use-case split is therefore straightforward. AMD holds a narrow legacy single-core win, while Intel claims modern single-core, all multi-core, all math, all encryption, all compression, and all sorting workloads. Any application that scales across cores, uses floating point heavily, or relies on encryption will benefit more from the Intel part according to this data.

Architecture Differences

The two processors come from different design philosophies. AMD uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, built on a combination of Zen 5 and Zen 5c cores. The process node is 4 nm, fabricated by TSMC. Intel's part is Lunar Lake, from the Core Ultra Series 2 generation, built on a 3 nm TSMC process. Both use TSMC as the foundry, but Intel's node is one step smaller.

Core counts differ significantly. AMD provides 4 cores and 8 threads, indicating simultaneous multithreading. Intel provides 8 cores and 8 threads, with no SMT. Despite having fewer threads, Intel wins all multi-threaded benchmarks, which indicates its cores are substantially more efficient per thread. The base clock for AMD is 2.00 GHz with a boost of 4.50 GHz. Intel starts at 2.20 GHz base and boosts to 5.00 GHz. Intel's boost advantage of 0.50 GHz likely contributes to its single-core and multi-core wins.

Cache hierarchies are very different. AMD allocates 80 KB of L1 per core, 1 MB of L2 per core, and 4 MB of shared L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. Intel's L3 cache is three times larger, which helps explain its advantage in memory-sensitive workloads like data compression and random string sorting. The larger per-core L2 also gives Intel more private cache for each thread.

Memory support diverges as well. AMD supports DDR5 and LPDDR5X with dual-channel memory and a bandwidth of 89.6 GB/s. Intel supports LPDDR5X, with the motherboard determining exact configurations, also dual-channel, but with a higher bandwidth of 136.5 GB/s. That 46.9 GB/s difference in peak bandwidth is a substantial architectural advantage for Intel. AMD supports ECC memory, while Intel does not, a notable difference for reliability-focused deployments. PCIe also differs: AMD offers Gen 4 with 14 CPU lanes, while Intel offers Gen 5 with 4 CPU lanes. Intel's generation is newer, but the lane count is much lower.

Integrated graphics differ as well. AMD includes the Radeon 840M, while Intel includes the Arc 140V. The benchmark data does not include GPU tests, so no performance conclusion can be drawn from this database, but the product names indicate different GPU architectures. TDP ratings show Intel at 17 watts versus AMD at 28 watts, a notable efficiency gap given Intel's performance wins. The sockets are incompatible: AMD uses Socket FP8, Intel uses BGA 2833.

The Verdict

The recorded data points to the Intel Core Ultra 7 266V as the stronger processor in nearly every measured category. It wins 14 of 15 head-to-head benchmarks, holds a higher average score, and reaches a higher percentile ranking. Its advantages span multi-core rendering, floating point math, encryption, compression, and modern single-core tests. The efficiency picture also favors Intel, since it delivers these results at 17 watts TDP versus AMD's 28 watts. The larger L3 cache, higher memory bandwidth, and smaller process node all align with the observed performance gaps.

The AMD Ryzen AI 5 430 is not without merit. It wins Cinebench R15 single-core, which indicates a specific strength in that legacy workload. It also supports ECC memory, which Intel does not, and offers more PCIe lanes at Gen 4, 14 lanes versus Intel's 4 lanes at Gen 5. For users prioritizing ECC support or older single-threaded workloads, the AMD part has a defined role. The data also shows AMD's nearest rivals include desktop parts like the Ryzen 5 5500 and Core i5-12500, with average scores very close to its own, which places it in a different performance class than the Intel part.

For any workload that benefits from multi-threading, modern single-core performance, or memory throughput, the Intel Core Ultra 7 266V is the clear choice according to the measurements. The only scenario where the AMD Ryzen AI 5 430 appears preferable is one where ECC memory support is mandatory, or where the specific Cinebench R15 single-core workload matters more than everything else recorded. The benchmark database shows a decisive overall win for Intel.
