AMD Ryzen Embedded 9950X3D vs Intel Core Ultra 7 266V Comparison

# Where Each One Wins

The Intel Core Ultra 7 266V shows measurable wins across a broad set of benchmarks, while the AMD Ryzen Embedded 9950X3D has no recorded benchmark scores in the database. The data indicates that the Intel part is the only one of the pair with a complete benchmark profile, and it holds a percentile ranking of 76 among all CPUs, whereas the AMD chip sits at the 50th percentile with no average score recorded.

The Core Ultra 7 266V delivers a single-thread score of 3943 in PassMark, which is the same value recorded for both the singlethread and single_thread tests. The AMD processor has no comparable PassMark entries, so the Intel part wins by default on every measured test. The Intel chip also produces an average benchmark score of 23297, which places it within 0.1% of the AMD Ryzen 7 5800H, 0.2% of the Intel Core i9-11900F, 0.3% of the Intel Core Ultra 9 288V, and 0.6% of the AMD EPYC 4124P. These nearest rivals all cluster within a narrow band, suggesting the Core Ultra 7 266V performs in a tightly contested segment.

For the Intel part, the strongest results come in multi-threaded workloads. Cinebench R23 multicore reaches 16544 points, while Cinebench R20 multicore scores 6948 and Cinebench R15 multicore scores 1667. PassMark multithread adds 19461 points. In single-core tests, the Intel chip records 2335 in Cinebench R23, 980 in Cinebench R20, and 235 in Cinebench R15. These figures show a large gap between its multicore and single-core capabilities, which is typical for a processor with 8 cores and 8 threads.

The AMD Ryzen Embedded 9950X3D has no benchmark entries, no wins, and no average score. Its percentile of 50 reflects the absence of measured performance data rather than a competitive position. The Intel part therefore takes every benchmark win by virtue of having recorded results, but the comparison is incomplete until the AMD chip receives benchmark coverage.

# Architecture Differences

The two processors differ substantially in core counts, cache hierarchies, process nodes, and platform targets. The AMD Ryzen Embedded 9950X3D uses 16 cores and 32 threads, while the Intel Core Ultra 7 266V uses 8 cores and 8 threads. The AMD part is a desktop processor in the 9000 series with the Granite Ridge codename, built on Zen 5 architecture at a 4 nm process node from TSMC. The Intel part is a mobile processor in the Core Ultra Series 2 with the Lunar Lake codename, built on a 3 nm process node, also from TSMC.

Cache configurations diverge significantly. The AMD chip provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of L3 cache. The Intel chip provides 192 KB of L1 per core, 2.5 MB of L2 per core, and only 12 MB of shared L3. The AMD part has a far larger total cache footprint, which can benefit workloads that repeatedly access large datasets. The Intel part uses a smaller L3 but larger per-core L1 and L2 allocations.

The AMD processor operates at a base clock of 4.30 GHz with a boost clock of 5.70 GHz, while the Intel processor runs at 2.20 GHz base and 5.00 GHz boost. The AMD chip has a 170 watt TDP, and the Intel chip has a 17 watt TDP. The Intel part is built for power efficiency, given its mobile market segment, while the AMD part targets desktop performance with a much higher power envelope.

Memory support also differs. The AMD chip supports DDR5 with dual-channel memory and a bandwidth of 89.6 GB/s, and it includes ECC memory support. The Intel chip supports LPDDR5X, which depends on the motherboard, also dual-channel, with a higher bandwidth of 136.5 GB/s, but it lacks ECC support. The Intel part uses an integrated Arc 140V GPU, while the AMD part includes Radeon Graphics. PCIe lane counts differ as well: the AMD chip provides Gen 5 with 24 CPU-only lanes, and the Intel chip provides Gen 5 with 4 CPU-only lanes.

The AMD processor has an unlocked multiplier, while the Intel processor is locked. The AMD chip uses AMD Socket AM5, and the Intel chip uses Intel BGA 2833. The AMD part is marked as active in production with a release date of 2025-10-06, and the Intel part is also active with a release date of 2024-09-23. The AMD chip carries the part number 100-000000719E, and the Intel chip carries SRPMMSRPMY.

# Head-to-Head Benchmarks

Since the AMD Ryzen Embedded 9950X3D has no recorded benchmark scores, every head-to-head comparison relies solely on the Intel Core Ultra 7 266V data. The database shows zero wins for the AMD chip and zero wins for the Intel chip in the headToHeadBenchmarks field, which means no direct paired tests exist between these two processors. The available benchmark results for the Intel part, however, provide a full performance profile.

The Intel Core Ultra 7 266V reaches 16544 points in Cinebench R23 multicore, which is its highest recorded Cinebench score. In Cinebench R20 multicore, it scores 6948, and in Cinebench R15 multicore, it scores 1667. The multicore results scale consistently across Cinebench versions, showing a roughly proportional increase from R15 to R20 to R23. Single-core results follow a similar pattern: 235 in Cinebench R15, 980 in Cinebench R20, and 2335 in Cinebench R23.

PassMark results for the Intel chip include data compression at 187050, data encryption at 13822, extended instructions at 15928, find prime numbers at 191, floating point math at 56923, integer math at 41558, multithread at 19461, physics at 1608, random string sorting at 22905, and single thread at 3943. The data compression score is the highest PassMark result, while find prime numbers is the lowest. The physics score of 1608 is relatively modest compared to the multithread score of 19461, indicating that the chip handles threaded workloads better than physics simulations.

The nearest rival comparisons for the Intel chip show a tight grouping. The AMD Ryzen 7 5800H has an average score of 23277 and a delta of 0.1%, meaning the Core Ultra 7 266V is effectively tied with it. The Intel Core i9-11900F scores 23254 with a 0.2% delta, the Intel Core Ultra 9 288V scores 23219 with a 0.3% delta, and the AMD EPYC 4124P scores 23167 with a 0.6% delta. These deltas are all within a single percentage point, so the Intel chip performs within a narrow range of those four rivals.

The absence of AMD benchmark data means the head-to-head analysis cannot show any AMD advantage. The Intel part stands as the only measured processor in this pairing, and its percentile of 76 indicates it ranks above the median CPU in the database. The AMD part's percentile of 50 is a placeholder value, not a performance metric.

# The Verdict

The data shows a clear split between the two processors. The Intel Core Ultra 7 266V has a complete benchmark profile with an average score of 23297 and a 76th percentile ranking. Its nearest rivals, including the AMD Ryzen 7 5800H, Intel Core i9-11900F, Intel Core Ultra 9 288V, and AMD EPYC 4124P, all fall within 0.6% of its average score, indicating that the Intel chip performs competitively within a tight band of similar processors. The Intel part's highest scores come in data compression and multithreaded Cinebench tests, and its low TDP of 17 watts makes it suitable for mobile platforms.

The AMD Ryzen Embedded 9950X3D has no benchmark scores, no average score, and no wins in the database. Its specifications show a high-core-count desktop processor with 16 cores, 32 threads, 128 MB of L3 cache, and a 170 watt TDP. The chip targets a different market segment, desktop rather than mobile, and its architecture features a much larger cache and higher clock speeds. However, without recorded benchmark data, the database cannot confirm any performance advantage.

For users selecting between these two processors, the choice depends on the available data. The Intel part is the only one with measured performance, and it delivers strong single-thread and multithread results within its power envelope. The AMD part offers more cores, more cache, and a higher boost clock on paper, but its performance remains unverified. The database records no head-to-head benchmarks between the two, so any direct comparison is limited to architectural specifications rather than measured outcomes. Based strictly on the data, the Intel Core Ultra 7 266V is the only processor with demonstrated benchmark results, while the AMD Ryzen Embedded 9950X3D remains an unmeasured quantity.
