AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 7 266V Comparison

AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 7 266V

The AMD Ryzen Embedded 9900X3D and the Intel Core Ultra 7 266V occupy different positions in the processor landscape, with the former being a high-core-count desktop part for embedded systems and the latter a low-power mobile chip. The database contains a complete benchmark profile for the Intel Core Ultra 7 266V, while the AMD Ryzen Embedded 9900X3D has no recorded benchmark scores, average score, or nearest rival entries. Consequently, the quantitative analysis in this article is drawn exclusively from the Intel part’s measured results and its position among similar processors, with the AMD chip’s characteristics described from its specification sheet.

Where Each One Wins

The recorded data places the Intel Core Ultra 7 266V in a clear position: it holds a 76th percentile ranking among all CPUs in the database, with an average benchmark score of 23,297. Its nearest rivals, all within a narrow band of performance, include the AMD Ryzen 7 5800H with an average score of 23,277 (a 0.1 percent difference), the Intel Core i9-11900F at 23,254 (0.2 percent), the Intel Core Ultra 9 288V at 23,219 (0.3 percent), and the AMD EPYC 4124P at 23,167 (0.6 percent). This clustering indicates that the Core Ultra 7 266V delivers performance that is statistically indistinguishable from these four processors in aggregate benchmarking, with the largest gap being less than one percent.

Within its own benchmark suite, the Intel chip shows specific strengths. In Cinebench R23, it scores 16,544 in multi-core and 2,335 in single-core. The single-core result places it in a strong position for lightly threaded tasks, as the score of 2,335 is achieved with a boost clock of 5.00 GHz across 8 cores and 8 threads. The multi-core score of 16,544 comes from those 8 cores with no simultaneous multithreading, meaning the chip relies on physical cores for all parallel workloads. In PassMark tests, the highest relative scores appear in data compression (187,050), floating point math (56,923), and integer math (41,558). These three results indicate that the processor handles compression algorithms and mathematical computation with particular efficiency, likely benefiting from its Lunar Lake architecture and the memory bandwidth of 136.5 GB/s.

The AMD Ryzen Embedded 9900X3D, by contrast, has no benchmark scores in the database. Its specification sheet reveals a different design philosophy: 12 cores and 24 threads, with a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The presence of simultaneous multithreading means the AMD part can process two threads per core, giving it 24 execution threads versus the Intel chip’s 8. The L3 cache of 128 MB is substantially larger than the Intel part’s 12 MB shared L3, and the AMD chip uses 4 nm process technology from TSMC with a die size of two 70.6 mm² chiplets. Without benchmark data, the database cannot confirm where the AMD part wins in measured performance, but the specification sheet suggests advantages in multi-threaded throughput, cache capacity, and clock speed headroom.

The Intel part clearly wins in power efficiency, as its thermal design power (TDP) is 17 watts versus the AMD chip’s 120 watts. The Core Ultra 7 266V also carries a smaller process node (3 nm vs 4 nm), which contributes to its lower power envelope. In memory bandwidth, the Intel chip’s 136.5 GB/s exceeds the AMD chip’s 89.6 GB/s. For integrated graphics, the Intel part uses Arc 140V, while the AMD part uses Radeon Graphics, though the database provides no comparative graphics benchmarks. The AMD chip wins on raw core count, thread count, clock speeds, and cache size, while the Intel chip wins on power, process node, and memory bandwidth.

The Verdict

The data presents a clear split: the Intel Core Ultra 7 266V is a measured performer with a 76th percentile ranking, while the AMD Ryzen Embedded 9900X3D is an unmeasured specification. For workloads that rely on single-thread performance, the Intel chip’s Cinebench R23 single-core score of 2,335 and PassMark single-thread score of 3,943 indicate strong capability. Its nearest rivals all fall within a 0.6 percent band, so the Core Ultra 7 266V delivers consistent, mid-high-tier performance for mobile or low-power systems.

For multi-threaded workloads, the Intel chip’s 8 cores and 8 threads produce a Cinebench R23 multi-core score of 16,544. This is respectable for a 17-watt part, but the AMD Ryzen Embedded 9900X3D’s 12 cores, 24 threads, and 5.50 GHz boost clock suggest a higher ceiling for parallel tasks. The AMD part’s 128 MB L3 cache and 120-watt TDP point to a design aimed at sustained throughput rather than power efficiency. The database has no measured scores for the AMD chip, so any claim of its superiority in multi-threaded work rests on its specifications, not on benchmark results.

Users who prioritize low power consumption, integrated graphics performance, and memory bandwidth should select the Intel Core Ultra 7 266V. Its 17-watt TDP, 136.5 GB/s memory bandwidth, and Arc 140V graphics make it suitable for compact, battery-conscious systems. Users who need maximum core count, thread count, and cache capacity, and who can tolerate a 120-watt TDP, should consider the AMD Ryzen Embedded 9900X3D. The AMD part also supports ECC memory, which the Intel part does not, a factor for reliability-sensitive embedded applications. The Intel chip is unlocked in terms of multiplier? No, the Intel part has a locked multiplier, while the AMD part is multiplier unlocked. That gives the AMD chip overclocking flexibility, though the database records no overclocking results.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, meaning there are no direct comparison scores between the AMD Ryzen Embedded 9900X3D and the Intel Core Ultra 7 266V. The only measured scores belong to the Intel chip. In Cinebench R15, the Intel part scores 1,667 multi-core and 235 single-core. In Cinebench R20, it scores 6,948 multi-core and 980 single-core. These results show a consistent ratio: multi-core scores are roughly 7 times the single-core scores, reflecting the 8 physical cores operating without hyperthreading.

The PassMark suite provides a broader view. The highest score is data compression at 187,050, which is more than 10 times the integer math score of 41,558. Floating point math scores 56,923, and extended instructions score 15,928. Random string sorting scores 22,905, and encryption scores 13,822. The multithread score is 19,461, and physics scores 1,608. Prime number finding scores only 191, which is the lowest result. This pattern suggests the Intel chip excels at compression and floating point operations but is weaker at prime number generation, a workload that often benefits from higher core counts.

The nearest rivals provide an indirect comparison. The AMD Ryzen 7 5800H, a mobile processor with 8 cores and 16 threads, scores an average of 23,277, just 0.1 percent below the Core Ultra 7 266V’s 23,297. The Intel Core i9-11900F, a desktop chip with 8 cores and 16 threads, scores 23,254, a 0.2 percent gap. The Intel Core Ultra 9 288V, the higher-bin version of the same Lunar Lake family, scores 23,219, 0.3 percent lower. The AMD EPYC 4124P, a server chip, scores 23,167, 0.6 percent lower. These margins are within typical run-to-run variance, so the Core Ultra 7 266V effectively ties all four rivals in aggregate performance.

No direct numbers compare the AMD Ryzen Embedded 9900X3D to the Intel chip. The AMD part’s base clock of 4.40 GHz is double the Intel chip’s 2.20 GHz base clock, and its boost clock of 5.50 GHz exceeds the Intel chip’s 5.00 GHz. The AMD chip has 1.5 times the cores and 3 times the threads. The L3 cache difference is stark: 128 MB versus 12 MB. These specifications imply that in multi-threaded benchmarks, the AMD part would likely score higher, but the database records no such scores. The Intel chip’s memory bandwidth of 136.5 GB/s is 52.7 percent higher than the AMD chip’s 89.6 GB/s, which could benefit memory-intensive workloads on the Intel side.

It uses a 4 nm process from TSMC and contains 16,630 million transistors across a die size of two 70.6 mm² chiplets. The Intel Core Ultra 7 266V is part of Core Ultra Series 2, codenamed Lunar Lake, built on a 3 nm process, also from TSMC. The Intel chip’s transistor count and die size are not recorded in the database.

The AMD part uses AMD Socket AM5, while the Intel part uses Intel BGA 2833. The AMD chip has an unlocked multiplier, allowing overclocking, while the Intel chip has a locked multiplier. The AMD part’s release date is 2025-10-06, and the Intel part’s release date is 2024-09-23. Both are listed as Active in production status.

Cache architecture differs fundamentally. The AMD chip has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of L3 cache. The Intel chip has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 12 MB of shared L3 cache. The AMD chip’s L3 cache is more than 10 times larger, which can reduce memory latency for repeated access patterns. The Intel chip’s larger per-core L1 and L2 caches may benefit single-threaded performance.

Memory support also differs. The AMD chip supports DDR5 in a dual-channel configuration with 89.6 GB/s bandwidth and ECC memory. The Intel chip supports LPDDR5X, with the specific configuration depending on the motherboard, also dual-channel but with 136.5 GB/s bandwidth and no ECC support. The Intel chip’s higher memory bandwidth reflects its mobile design, where integrated memory controllers often use faster low-power memory.

PCI Express connectivity differs significantly. The AMD chip provides Gen 5 with 24 lanes from the CPU, while the Intel chip provides Gen 5 with only 4 lanes. This makes the AMD part suitable for systems with multiple high-speed add-in cards or NVMe drives, while the Intel part is limited to a single PCIe device or a small number of lanes.

Integrated graphics differ: the AMD chip uses Radeon Graphics, while the Intel chip uses Arc 140V. The database provides no graphics benchmarks for either. The Intel chip’s market segment is Mobile, while the AMD chip’s is Desktop. The AMD part has a TDP of 120 watts, the Intel part has a TDP of 17 watts. The AMD part’s base clock is 4.40 GHz and boost clock is 5.50 GHz; the Intel part’s base clock is 2.20 GHz and boost clock is 5.00 GHz. The AMD chip’s part number is 100-000001368E, and the Intel chip’s part number is SRPMMSRPMY. Neither has a recorded launch MSRP.

The process node difference (4 nm AMD vs 3 nm Intel) and the TDP difference (120 W vs 17 W) explain the design intent. The AMD chip targets embedded desktops where power is available and performance is paramount. The Intel chip targets mobile devices where efficiency is critical. The database’s measured scores for the Intel chip confirm that its 8 cores can compete with older 8-core/16-thread parts like the Ryzen 7 5800H and Core i9-11900F, while its power draw remains low. The AMD chip, with no measured scores, remains a specification-driven alternative with a substantial core and cache advantage.
