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

The Verdict

The recorded data places these two processors at opposite ends of the computing spectrum. The AMD Ryzen Embedded 9950X is a 16-core, 32-thread desktop processor built on the Granite Ridge architecture with a 170 TDP, while the Intel Core Ultra 7 266V is an 8-core, 8-thread mobile processor on Lunar Lake with a 17 TDP. The Intel part holds a 76th percentile ranking among all CPUs versus the AMD part's 50th percentile, and the Intel's average benchmark score of 23,297 dwarfs the AMD's recorded average of 0, which reflects that no benchmark results exist for the AMD in the database at this time.

The Intel Core Ultra 7 266V is the only processor with measurable performance data, and it demonstrates strong capabilities across both single-thread and multi-thread workloads. The AMD Ryzen Embedded 9950X, despite its larger core count and higher clock speeds, has no recorded benchmark scores, making direct performance comparison impossible from the available facts. The data clearly favors the Intel part for any workload where measured results matter, but the AMD part's specifications suggest it targets a different use case entirely.

For users who need verified performance numbers today, the Intel Core Ultra 7 266V is the only choice supported by data. For those who prioritize raw core counts, higher boost clocks, and server-oriented features like ECC memory support, the AMD Ryzen Embedded 9950X offers specifications that the Intel part cannot match, though its actual performance remains unverified in this database.

Where Each One Wins

The Intel Core Ultra 7 266V wins every benchmark category where scores are recorded. In Cinebench R23 multi-core, it scores 16,544, and in single-core, it scores 2,335. The Cinebench R20 results show 6,948 multi-core and 980 single-core, while Cinebench R15 shows 1,667 multi-core and 235 single-core. PassMark tests reveal a single-thread score of 3,943, a multi-thread score of 19,461, and an average benchmark score of 23,297, placing it 0.1% ahead of the AMD Ryzen 7 5800H, 0.2% ahead of the Intel Core i9-11900F, 0.3% ahead of the Intel Core Ultra 9 288V, and 0.6% ahead of the AMD EPYC 4124P.

The AMD Ryzen Embedded 9950X wins in specification-based categories. It offers 16 cores and 32 threads versus the Intel's 8 cores and 8 threads, a boost clock of 5.70 GHz versus 5.00 GHz, a base clock of 4.30 GHz versus 2.20 GHz, and 64 MB of L3 cache versus 12 MB. It supports ECC memory, which the Intel part does not, and it provides 28 PCIe Gen 5 lanes from the CPU versus the Intel's 4 lanes. The AMD also has an unlocked multiplier, while the Intel is locked.

The Intel part wins in efficiency-oriented specifications. Its 17 TDP is drastically lower than the AMD's 170, its 3 nm process node is smaller than the AMD's 4 nm, and its memory bandwidth of 136.5 GB/s exceeds the AMD's 89.6 GB/s. The Intel also integrates the Arc 140V graphics, while the AMD uses Radeon Graphics.

Architecture Differences

The AMD Ryzen Embedded 9950X uses the Granite Ridge codename and belongs to the Ryzen Embedded generation built on Zen 5 architecture. It is manufactured by TSMC on a 4 nm process node with 16,630 million transistors and a die size of 2x 70.6 mm². The Intel Core Ultra 7 266V uses the Lunar Lake codename and belongs to the Core Ultra Series 2 generation. It is also manufactured by TSMC, but on a 3 nm process node, with no transistor count or die size recorded.

Cache hierarchies differ substantially. The AMD provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. The Intel provides 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 12 MB of shared L3 cache. The Intel's larger per-core L1 and L2 caches contrast with the AMD's much larger L3 pool.

Memory support diverges as well. The AMD supports DDR5 memory on a dual-channel bus with 89.6 GB/s bandwidth and ECC memory capability. The Intel supports LPDDR5X memory, which depends on the motherboard, on a dual-channel bus with 136.5 GB/s bandwidth and no ECC support. PCIe connectivity differs significantly, with the AMD offering Gen 5 with 28 lanes from the CPU only, while the Intel offers Gen 5 with just 4 lanes from the CPU only.

The AMD uses the AMD Socket AM5, has an unlocked multiplier, and carries the part number 100-000001277E. The Intel uses Intel BGA 2833, has a locked multiplier, and carries the part number SRPMMSRPMY. The AMD was released on 2025-10-06, while the Intel was released on 2024-09-23. The AMD targets the desktop market segment, while the Intel targets mobile.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons are impossible because the AMD Ryzen Embedded 9950X has no recorded scores in any test. The database shows zero benchmark entries for the AMD part, while the Intel Core Ultra 7 266V has complete results across Cinebench and PassMark suites.

The Intel Core Ultra 7 266V delivers a Cinebench R23 multi-core score of 16,544 and a single-core score of 2,335. In Cinebench R20, it scores 6,948 multi-core and 980 single-core. Cinebench R15 results show 1,667 multi-core and 235 single-core. These results indicate strong performance in both heavily threaded and lightly threaded workloads.

PassMark results for the Intel part cover multiple specialized tests. Data compression scores 187,050, data encryption scores 13,822, extended instructions score 15,928, and finding prime numbers scores 191. Floating point math scores 56,923, integer math scores 41,558, and random string sorting scores 22,905. Physics scores 1,608, and single-thread performance scores 3,943.

The Intel's average benchmark score of 23,297 places it in the 76th percentile of all CPUs. Its nearest rivals are closely clustered: the AMD Ryzen 7 5800H is 0.1% behind, the Intel Core i9-11900F is 0.2% behind, the Intel Core Ultra 9 288V is 0.3% behind, and the AMD EPYC 4124P is 0.6% behind. This tight grouping suggests the Intel part performs at a consistent level relative to established desktop and mobile processors.

The AMD Ryzen Embedded 9950X's specifications indicate untested potential. Its 16 cores, 32 threads, 5.70 GHz boost clock, and 64 MB L3 cache would likely produce competitive multi-threaded scores if benchmarked, but the database contains no evidence to confirm this. The Intel part's 8 cores and 8 threads with a 5.00 GHz boost clock and 12 MB L3 cache have proven results, but the AMD's architectural advantages in core count, cache size, and clock speed remain theoretical until measured.

The power envelope difference is stark. The AMD's 170 TDP versus the Intel's 17 TDP represents a tenfold difference in thermal design power, which affects cooling requirements, system size, and sustained workload capability. The AMD's higher power budget supports its larger core count and higher clocks, while the Intel's minimal power draw enables mobile deployment. The process node difference, 4 nm for AMD versus 3 nm for Intel, partially explains the efficiency gap, though both parts come from TSMC.

The AMD's PCIe lane count of 28 versus the Intel's 4 provides significantly more expansion capability for add-in devices, storage controllers, or networking hardware. The AMD's ECC memory support adds reliability for data-sensitive applications, while the Intel's lack of ECC support and dependence on motherboard-specific LPDDR5X memory configurations narrow its deployment options. The AMD's unlocked multiplier allows overclocking, while the Intel's locked multiplier prevents it.

The release dates show the AMD arrived about a year after the Intel, on 2025-10-06 versus 2024-09-23. Both parts remain in active production. The AMD's desktop market segment and socket AM5 platform contrast with the Intel's mobile segment and BGA 2833 socket, which means the two processors are not interchangeable in any system. Buyers must choose based on platform requirements, not just raw specifications.
