AMD Ryzen AI 5 440G vs Intel Core Ultra 7 266V Comparison

The AMD Ryzen AI 5 440G and the Intel Core Ultra 7 266V occupy different positions in the desktop and mobile processor landscape. The data shows a clear split: the AMD part leverages a higher thread count and larger cache configuration to dominate integer-heavy and compression workloads, while the Intel part, with its lower power envelope and different core architecture, counters in floating-point math, physics, and prime number calculations. Their average benchmark scores, 46187 for the AMD and 23297 for the Intel, reflect this divergence, placing them in entirely different performance tiers.

Where Each One Wins

The AMD Ryzen AI 5 440G wins 7 of the 11 recorded head-to-head benchmarks. Its strongest advantages come in integer math, where it scores 71251 against Intel's 41558, a 71.4% lead, and in data compression, where it reaches 292735 versus 187050, a 56.5% margin. These results indicate that workloads relying on arithmetic logic, sorting, and data packing will favor the AMD processor. The multithread score of 23487 versus 19461, a 20.7% advantage, confirms that the AMD part sustains its lead when all cores are active. Random string sorting also goes to AMD with a 35.8% delta, and extended instructions show a 29.6% edge.

The Intel Core Ultra 7 266V wins the remaining 4 benchmarks, but they are specific in nature. Its floating-point math score of 56923 beats AMD's 45711 by 19.7%, and its physics score of 1608 beats 1329 by 17.4%. Prime number finding shows the largest relative win for Intel, a 52.9% delta with scores of 191 versus 90. Data encryption is a narrow Intel victory, 13822 against 13585, a 1.7% difference. These wins point to scenarios where heavy FPU usage, simulation physics, and cryptographic single-thread operations run faster on the Intel chip.

Architecture Differences

The AMD Ryzen AI 5 440G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation with a hybrid Zen 5 and Zen 5c core design. It is built on TSMC's 4 nm process with a die size of 195 mm². The processor has 6 cores and 12 threads, with a base clock of 2.00 GHz and a boost clock of 4.80 GHz. Its cache structure includes 80 KB of L1 per core, 1 MB of L2 per core, and 8 MB of L3. Memory support is DDR5 over a dual-channel bus, providing 89.6 GB/s of bandwidth, and ECC memory is supported. The chip runs on the AMD Socket AM5 platform, supports PCIe Gen 4 with 12 CPU lanes, and features a Radeon 840M integrated GPU. It has a 65 W TDP and an unlocked multiplier.

The Intel Core Ultra 7 266V is part of the Core Ultra Series 2, based on the Lunar Lake architecture. It is fabricated on a 3 nm TSMC process. This chip has 8 cores and 8 threads, with no hyperthreading, a base clock of 2.20 GHz, and a boost clock of 5.00 GHz. Its cache is larger per core: 192 KB of L1, 2.5 MB of L2, and a shared 12 MB of L3. Memory support is LPDDR5X, dual-channel, with a higher bandwidth of 136.5 GB/s, but ECC is not supported. The socket is Intel BGA 2833, and it uses PCIe Gen 5 with 4 CPU lanes. Integrated graphics come from the Arc 140V. The TDP is much lower at 17 W, and the multiplier is locked. The Intel part also supports no ECC memory.

The process node advantage goes to Intel at 3 nm versus 4 nm, but the AMD chip counters with more threads and a higher power budget. The Intel part's memory bandwidth is 52.4% higher (136.5 GB/s versus 89.6 GB/s), which may contribute to its floating-point performance. The AMD chip's PCIe Gen 4 with 12 lanes offers more platform connectivity than Intel's Gen 5 with 4 lanes, though Intel's PCIe generation is newer.

Head-to-Head Benchmarks

The largest single benchmark delta in the comparison is integer math. The AMD Ryzen AI 5 440G scores 71251, which is 71.4% higher than the Intel Core Ultra 7 266V's 41558. This is a substantial gap, indicating that the AMD core design, with its extra threads, handles integer operations far more efficiently. Data compression shows a similar pattern: 292735 for AMD versus 187050 for Intel, a 56.5% lead. Random string sorting follows with a 35.8% advantage for AMD (31106 versus 22905). Extended instructions also favor AMD, with a score of 20648 versus 15928, a 29.6% delta.

Intel's most decisive win is in prime number finding, where it scores 191 against AMD's 90, a 52.9% margin. This test often relies on specific integer branch prediction and loop efficiency, where Intel's architecture shows strength. Floating-point math is another clear Intel win, 56923 versus 45711, a 19.7% delta. Physics simulation scores also go to Intel, 1608 versus 1329, a 17.4% lead. The narrowest win in the entire comparison is data encryption, where Intel edges AMD by only 1.7% (13822 versus 13585).

In single-thread performance, AMD takes a small lead. The passmark single-thread score is 4060 for AMD versus 3943 for Intel, a 3% delta. The multithread score shows a larger AMD advantage, 23487 versus 19461, a 20.7% delta. The overall average benchmark scores reinforce this split: AMD's avgBenchmarkScore is 46187, while Intel's is 23297.

The Verdict

The recorded data shows two distinct usage profiles. The AMD Ryzen AI 5 440G is the stronger choice for integer-heavy computation, data compression, and multithreaded workloads. Its 71.4% lead in integer math and 56.5% lead in data compression, combined with a 20.7% multithread advantage, make it the more capable processor for general productivity, database operations, and parallel processing tasks. The 12 threads and unlocked multiplier support this positioning.

The Intel Core Ultra 7 266V is the better option for floating-point math, physics simulation, and prime number calculations, where it wins by 19.7%, 17.4%, and 52.9% respectively. Its 5.00 GHz boost clock and higher memory bandwidth of 136.5 GB/s may explain these results. The 17 W TDP also indicates a much more power-efficient design, suitable for constrained thermal environments. However, the Intel part's 8 threads and locked multiplier limit its ceiling in heavily threaded applications.

For users prioritizing maximum integer throughput and compression speed, the AMD Ryzen AI 5 440G is the data-backed choice. For workloads that stress floating-point units and simulation physics, the Intel Core Ultra 7 266V delivers the higher scores. The overall percentile ranking, 89th for AMD versus 76th for Intel, aligns with the average score difference, but the specific benchmark wins clarify that neither chip dominates across all categories.
