AMD Ryzen Embedded 9950X3D vs Intel Core Ultra 5 250KF Plus Comparison

The AMD Ryzen Embedded 9950X3D and the Intel Core Ultra 5 250KF Plus are desktop processors from different design philosophies. The AMD part is a 16-core, 32-thread Granite Ridge chip with a 128 MB L3 cache and a 4 nm process, while the Intel part is an 18-core, 18-thread Arrow Lake Refresh chip with a 30 MB shared L3 cache and a 3 nm process. The database contains a comprehensive benchmark suite for the Intel processor, while the AMD processor currently has no recorded benchmark scores. The Intel Core Ultra 5 250KF Plus achieves an average benchmark score of 66,159 and sits at the 93rd percentile of all CPUs in the database. The AMD Ryzen Embedded 9950X3D holds a 50th percentile ranking with an average benchmark score of zero, indicating a lack of tested performance data. The disparity in available measurements shapes the analysis, as the Intel part can be directly assessed against rivals while the AMD part must be examined on architectural merits alone.

Head-to-Head Benchmarks

The database does not contain a direct head-to-head benchmark comparison between the AMD Ryzen Embedded 9950X3D and the Intel Core Ultra 5 250KF Plus. No shared workload results are recorded for both processors, so a side-by-side score comparison cannot be produced from the recorded data. The Intel processor has 17 benchmark entries covering Cinebench R15, R20, R23, and Passmark tests, while the AMD processor has no benchmark entries at all. This means the Intel part can be evaluated in absolute terms and against its nearest rivals, but the AMD part cannot be positioned against the Intel part using measured scores.

The Intel Core Ultra 5 250KF Plus delivers a Cinebench R23 multicore score of 42,718 and a single-core score of 6,030. In Cinebench R20, it records 17,941 multicore and 2,532 single-core. The Cinebench R15 results are 4,305 multicore and 607 single-core. These numbers show a processor with strong multi-threaded throughput relative to its single-thread performance. The Passmark suite reinforces this pattern. The processor scores 50,146 in the Passmark multithread test and 4,698 in the Passmark single-thread test. The floating point math score is 159,824, integer math is 123,030, and extended instructions is 42,880. Data compression reaches 553,155, while data encryption records 41,292. The find prime numbers test produces 452, random string sorting hits 67,209, and physics scores 3,183.

Against its nearest rivals, the Intel Core Ultra 5 250KF Plus is nearly level with several high-end parts. It trails the Intel Core Ultra 5 250K Plus by 1 percent in average score, with the rival recording 66,855 against 66,159. The AMD EPYC 4465P is 1.1 percent ahead at 66,925. The AMD Ryzen 9 7950X3D sits 0.4 percent behind the Intel part, averaging 65,914, while the Intel Core 9 273PQE is 0.1 percent behind at 66,099. These deltas indicate the Core Ultra 5 250KF Plus performs within a narrow band of these competitors. The most significant gap is the 1.1 percent difference against the EPYC 4465P, which is a small margin in practical terms. The processor's 93rd percentile ranking confirms it sits above the majority of CPUs in the database, though the 50th percentile of the AMD part cannot be compared due to missing data.

Architecture Differences

The two processors diverge sharply in core topology. The AMD Ryzen Embedded 9950X3D has 16 cores and 32 threads, which indicates simultaneous multithreading is enabled. The Intel Core Ultra 5 250KF Plus has 18 cores and 18 threads, meaning it runs one thread per core without hyper-threading. The AMD part's thread count is nearly double its core count, while the Intel part has no thread advantage. The base clocks are close, with the AMD at 4.30 GHz and the Intel at 4.20 GHz, but the boost clocks differ more substantially. The AMD boosts to 5.70 GHz, while the Intel reaches 5.30 GHz. The AMD part also carries a higher TDP of 170 watts against the Intel's 125 watts.

Cache structures show a major differentiation. The AMD processor uses 80 KB of L1 cache per core, 1 MB of L2 cache per core, and a large 128 MB L3 cache. The Intel processor uses 192 KB of L1 per core, 3 MB of L2 per core, and a 30 MB shared L3 cache. The AMD's 128 MB L3 is more than four times the Intel's 30 MB, which favors workloads that repeatedly access a large working set. The Intel part has a larger per-core L2 allocation, 3 MB versus 1 MB, which can help with per-core data locality. The total transistor counts are comparable, with AMD at 16,630 million and Intel at 17,800 million, but the die size differs dramatically. The AMD uses two chiplets at 2x 70.6 mm², for a combined 141.2 mm², while the Intel uses a monolithic 243 mm² die. The AMD's smaller combined die area reflects its chiplet design, while the Intel's larger single die consolidates all 18 cores.

Memory support is similar in type, as both use DDR5 with dual-channel buses. The memory bandwidth differs, with the AMD at 89.6 GB/s and the Intel at 115.2 GB/s. Both support ECC memory. PCIe connectivity also varies. The AMD provides Gen 5 with 24 lanes from the CPU, while the Intel provides Gen 5 with 20 lanes from the CPU. The AMD integrates Radeon Graphics, while the Intel lists N/A for integrated graphics, meaning the Intel part requires a discrete GPU. Both processors have unlocked multipliers, allowing overclocking. The AMD uses Socket AM5, and the Intel uses Socket 1851. The AMD is part of the 9000 series with the Granite Ridge codename and Zen 5 architecture, while the Intel is part of the Core Ultra Series 2 with the Arrow Lake Refresh codename. The AMD was released on 2025-10-06, and the Intel was released on 2026-03-10.

The Verdict

The recorded data supports a clear choice for users who rely on measured performance: the Intel Core Ultra 5 250KF Plus is the only one of the two with benchmark results. Its average score of 66,159 places it in the 93rd percentile, and it competes within 1.1 percent of the AMD EPYC 4465P and within 1 percent of the Intel Core Ultra 5 250K Plus. The AMD Ryzen Embedded 9950X3D has no recorded scores, so its performance cannot be confirmed from the database. A user selecting between these two parts based on data would choose the Intel processor because it has verified results. The AMD part's 128 MB L3 cache and higher boost clock suggest potential in cache-sensitive tasks, but without scores, that potential remains unmeasured. The Intel part also has a launch MSRP of $184, which is a listed price point. The AMD part has no launch MSRP in the database. The Intel part's 18 cores at 18 threads, 5.30 GHz boost, and 115.2 GB/s memory bandwidth make it a strong candidate for multi-threaded workloads based on the recorded Cinebench and Passmark scores. The AMD part's 16 cores at 32 threads and 5.70 GHz boost could theoretically compete, but the absence of data prevents a definitive verdict.

Where Each One Wins

Based strictly on the recorded data, the Intel Core Ultra 5 250KF Plus wins in all measured categories because it is the only processor with benchmark scores. It demonstrates strong multi-threaded performance with a Cinebench R23 multicore score of 42,718 and a Passmark multithread score of 50,146. Its single-thread results are also solid, with a Cinebench R23 single-core score of 6,030 and a Passmark single-thread score of 4,698. The Intel part excels in data compression with a Passmark score of 553,155 and floating point math at 159,824. These scores indicate it is well suited for rendering, scientific computation, and data processing tasks. The AMD Ryzen Embedded 9950X3D has no recorded wins in any benchmark category. Its architectural features, such as the 128 MB L3 cache and 32 threads, may favor workloads that benefit from large cache capacity and high thread counts, but the database contains no evidence of such wins. The AMD part's higher boost clock of 5.70 GHz could suggest an advantage in lightly threaded tasks, but no single-thread score exists to confirm this. The Intel part's higher memory bandwidth of 115.2 GB/s supports memory-intensive workloads, and its 18 physical cores provide raw parallel throughput. The AMD part's dual-channel 89.6 GB/s bandwidth is lower, which could limit performance in memory-bound scenarios. In terms of production status, both are active. The Intel part's 93rd percentile ranking places it well above the AMD part's 50th percentile, though the latter is based on zero scores. For any workload where measured performance matters, the Intel Core Ultra 5 250KF Plus is the recorded winner. The AMD part remains an unverified option with a larger cache and more threads, but the data does not support a win in any category.
