The average benchmark scores differ notably. AMD's average sits at 37762, while Intel's average is 23297. This discrepancy reflects the test suite composition: the AMD average includes a very high compression score that skews the mean upward. Intel's nearest rivals include the AMD Ryzen 7 5800H at 23277 (0.1% behind), Intel Core i9-11900F at 23254 (0.2% behind), Intel Core Ultra 9 288V at 23219 (0.3% behind), and AMD EPYC 4124P at 23167 (0.6% behind). AMD's nearest rivals are the AMD Ryzen AI Embedded P132 at 37804 (0.1% behind), Intel Core 5 211E at 37829 (0.2% behind), Intel Core i5-13600K at 37685 (0.2% ahead), and AMD Ryzen AI 9 HX 370 at 37904 (0.4% behind).

Architecture Differences

The two processors come from different design philosophies. AMD uses a 4 nm process node from TSMC, while Intel uses a 3 nm node, also from TSMC. AMD's architecture is Zen 5 under the codename Gorgon Point, part of the Ryzen AI PRO 400 generation that combines Zen 5 and Zen 5c cores. Intel's architecture is Lunar Lake, part of the Core Ultra Series 2 generation.

Core counts diverge significantly. The AMD part has 6 cores and 12 threads, while the Intel part has 8 cores and 8 threads. This means AMD relies on simultaneous multithreading to reach 12 threads, while Intel runs one thread per core. Base clocks are close: AMD starts at 2.00 GHz, Intel at 2.20 GHz. Boost clocks favor Intel at 5.00 GHz versus 4.50 GHz for AMD.

Cache layouts differ substantially. AMD provides 80 KB of L1 cache per core, 1 MB of L2 per core, and only 4 MB of L3 cache. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3. The Intel L3 cache is three times larger than AMD's total L3 capacity, which helps explain Intel's advantage in multi-threaded and physics workloads.

Memory support shows another split. Both support dual-channel memory. AMD lists DDR5 and LPDDR5X support with 89.6 GB/s bandwidth and ECC memory support. Intel lists LPDDR5X support dependent on motherboard, with 136.5 GB/s bandwidth and no ECC support. The Intel memory bandwidth is 52.3% higher than AMD's, which contributes to Intel's floating point and encryption performance.

PCIe connectivity differs by generation and lane count. AMD offers PCIe Gen 4 with 14 CPU lanes. Intel offers PCIe Gen 5 with 4 CPU lanes. The AMD part provides more lanes for peripheral expansion, while Intel's fewer lanes run at a newer generation.

Integrated graphics also differ. AMD uses the Radeon 840M, while Intel uses the Arc 140V. The socket types are incompatible: AMD uses AMD Socket FP8, Intel uses Intel BGA 2833. Both processors are mobile segments, active in production, and neither has an unlocked multiplier.

Power ratings show a notable difference. AMD has a TDP of 28 watts, while Intel has a TDP of 17 watts. The Intel part delivers its performance within a lower thermal envelope, while AMD uses more power budget. Both are soldered mobile parts with no upgrade path.

Release dates differ by over a year. Intel launched on 2024-09-23, while AMD's release date is 2026-01-04. The Intel part has been in the market longer.

Where Each One Wins

The data supports a clear division of strengths. AMD wins in integer math, data compression, random string sorting, and extended instructions. These workloads share a pattern: they involve processing discrete data chunks, sorting operations, and instruction-level parallelism that benefits from AMD's 12 threads. The 46.5% integer math lead and 24.5% compression lead indicate that AMD's architecture handles integer-heavy data manipulation more efficiently.

Intel wins in prime number finding, floating point math, physics, data encryption, single-thread performance, and multithread performance. The 70.2% prime number lead and 38.1% physics lead suggest Intel's per-core efficiency is superior for sequential and floating point heavy tasks. The 27.8% floating point advantage reinforces this pattern. Intel's higher boost clock of 5.00 GHz and larger L3 cache of 12 MB support these results.

For single-threaded responsiveness, Intel holds the edge at 3943 versus 3757, a 4.7% margin. This translates to faster reaction in applications that cannot use multiple cores. The multithread score is nearly even at 19461 versus 19091, only 1.9% apart, despite Intel having fewer threads. This near-parity in multithread performance, achieved with 8 threads against AMD's 12, indicates Intel's cores extract more work per thread.

The percentile rankings reflect overall positioning. AMD sits at the 86th percentile among all CPUs, while Intel sits at the 76th percentile. Despite Intel winning more head-to-head tests, AMD's average score places it higher in the overall distribution. This happens because AMD's compression score of 232803 is an outlier that lifts its average significantly.

Workloads involving data encryption favor Intel by 18.5%. This includes common tasks like disk encryption and secure communications. Floating point math workloads such as scientific calculations, 3D rendering, and audio processing favor Intel by 27.8%. Prime number finding, relevant to cryptography and mathematical computation, heavily favors Intel by 70.2%.

Workloads involving compression, such as file archiving and database operations, favor AMD by 24.5%. Integer math, used in general application logic and many business applications, favors AMD by 46.5%. Random string sorting, relevant to database indexing and text processing, favors AMD by 8.9%.

The Verdict

The data points to distinct use cases for each processor. The AMD Ryzen AI 5 PRO 435 delivers its strongest results in integer math, data compression, and string sorting. These workloads appear in database operations, file archiving, business application logic, and text processing. The 46.5% integer math advantage and 24.5% compression advantage make AMD the stronger choice for data-centric mobile workstations.

The Intel Core Ultra 7 266V dominates floating point, physics, encryption, and single-thread performance. The 70.2% prime number lead, 27.8% floating point lead, and 38.1% physics lead indicate superiority in scientific computing, 3D rendering, cryptography, and simulation workloads. The 4.7% single-thread advantage also gives Intel faster response in lightly threaded applications.

Power efficiency favors Intel. At 17 watts TDP versus AMD's 28 watts, Intel delivers competitive multithread performance (within 1.9%) while consuming less power budget. The Intel part also offers higher memory bandwidth at 136.5 GB/s versus 89.6 GB/s, which supports its floating point and encryption results.

The AMD part offers more threads at 12 versus 8, ECC memory support, and more PCIe lanes at 14 versus 4. These features matter for reliability-focused deployments and systems requiring more expansion connectivity. The AMD part also sits at the 86th percentile overall versus Intel's 76th percentile, though this reflects the influence of AMD's outlier compression score.

Intel's larger L3 cache at 12 MB versus 4 MB and higher boost clock at 5.00 GHz versus 4.50 GHz explain its single-thread and floating point advantages. The smaller process node at 3 nm versus 4 nm contributes to Intel's lower TDP.

The verdict from the recorded data: choose the AMD Ryzen AI 5 PRO 435 for integer-heavy data processing, compression workloads, and applications that benefit from 12 threads plus ECC memory support. Choose the Intel Core Ultra 7 266V for floating point intensive tasks, physics simulation, encryption, single-thread responsiveness, and lower power consumption. The 7 to 4 win count in Intel's favor reflects broader benchmark coverage, but the AMD wins are concentrated in workloads that matter for data manipulation and general business computing.
