AMD Ryzen Embedded 9950X3D vs Intel Core Ultra 7 258V Comparison

The AMD Ryzen Embedded 9950X3D and Intel Core Ultra 7 258V serve entirely different segments of the processor market. The Ryzen Embedded part is a 16-core desktop-class processor built for high-throughput workloads, while the Core Ultra 7 258V is an 8-core mobile processor designed for efficiency. The recorded data shows a clear split in their intended use cases, and the benchmark results, where available, quantify that split.

Where Each One Wins

The Intel Core Ultra 7 258V is the only one of the two with recorded benchmark scores in the database. It holds a 74th percentile ranking among all CPUs, with an average benchmark score of 20454. Its nearest rivals in the database are the AMD Ryzen 5 5600, which scores 20468 and trails by 0.1 percent, the AMD Ryzen 5 8500G at 20425, which is 0.1 percent behind, the AMD EPYC 9454P at 20422, which is 0.2 percent behind, and the AMD EPYC 7713 at 20363, which is 0.4 percent behind. These margins are small, meaning the Core Ultra 7 258V sits in a competitive band of processors that cluster closely together.

For the AMD Ryzen Embedded 9950X3D, the database contains no benchmark scores, no average score, and no nearest rivals. Its percentile ranking is 50, which is the midpoint of the distribution, but this is not derived from any recorded test results. The data cannot confirm where this processor wins because no measurements exist for it. What the data does show is the structural advantage of the Ryzen part: 16 cores and 32 threads versus 8 cores and 8 threads, a 5.70 GHz boost clock versus 4.80 GHz, and 128 MB of L3 cache versus 12 MB. These specifications point to workloads that scale with core count, cache size, and raw clock speed, such as rendering, compilation, and server-side processing. The Intel part, with its 17 W TDP and integrated Arc 140V graphics, is positioned for mobile systems where power draw is the limiting factor.

The recorded benchmarks for the Core Ultra 7 258V show strength in single-threaded tasks. It scores 1872 in Cinebench R23 single-core, 951 in Cinebench R20 single-core, and 285 in Cinebench R15 single-core. Its Geekbench single-core score is 2100. In Passmark single-thread tests it records 4018. These numbers indicate a processor that handles lightly threaded workloads well, which is typical for mobile productivity and everyday computing. Multi-threaded scores are present but lower in relative terms: Cinebench R23 multi-core is 10301, Cinebench R20 multi-core is 6739, and Cinebench R15 multi-core is 1596.5. The gap between single-core and multi-core results is consistent with an 8-core, 8-thread design without simultaneous multithreading.

Architecture Differences

The two processors come from different manufacturing nodes and design philosophies. The AMD Ryzen Embedded 9950X3D is built on a 4 nm process at TSMC, while the Intel Core Ultra 7 258V uses a 3 nm process, also from TSMC. The AMD part uses the Granite Ridge codename and belongs to the Ryzen Embedded generation built on Zen 5 (Granite Ridge). The Intel part uses the Lunar Lake architecture and belongs to the Core Ultra Series 2 generation. Both are active production parts.

The transistor count and die size are only recorded for the AMD part. The Ryzen Embedded 9950X3D has 16,630 million transistors and a die size of 2x 70.6 mm². No transistor count or die size is recorded for the Intel part. The cache hierarchy differs substantially. The AMD processor has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 128 MB of L3 cache. The Intel processor has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 12 MB of shared L3 cache. The larger L3 cache on the AMD part is a defining feature, as it offers more than ten times the L3 capacity of the Intel part.

Memory support also differs. The AMD processor uses DDR5 memory with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Intel processor uses LPDDR5X memory with a dual-channel bus and a higher recorded memory bandwidth of 136.5 GB/s. ECC memory is supported on the AMD part but not on the Intel part. PCIe connectivity differs as well: the AMD processor provides Gen 5 with 24 lanes (CPU only), while the Intel processor provides Gen 5 with 4 lanes (CPU only). The integrated graphics are different: the AMD part uses Radeon Graphics, while the Intel part uses Arc 140V.

The Intel processor has a TDP of 17 W, which is characteristic of a low-power mobile design. The AMD processor has a TDP of 170 W, ten times higher, which requires substantial cooling and power delivery. The AMD part uses AMD Socket AM5, while the Intel part uses Intel BGA 2833, a soldered mobile socket. The multiplier is unlocked on the AMD part, allowing overclocking, while the Intel part has a locked multiplier.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, and the win counts for both processors are zero. This means no direct comparison measurements exist between the AMD Ryzen Embedded 9950X3D and the Intel Core Ultra 7 258V. The only benchmark scores recorded are for the Intel part, and those scores stand alone without a rival comparison.

The Intel Core Ultra 7 258V delivers a Cinebench R23 multi-core score of 10301 and a single-core score of 1872. In Cinebench R20, it scores 6739 multi-core and 951 single-core. In Cinebench R15, it scores 1596.5 multi-core and 285 single-core. Geekbench results are 9325 multi-core and 2100 single-core. Passmark results include a multithread score of 18887, a single-thread score of 4018, floating point math at 57372, integer math at 42889, extended instructions at 14717, data compression at 176686, data encryption at 13534, random string sorting at 21580, physics at 1565, and find prime numbers at 185.

These scores place the Intel part at the 74th percentile among all CPUs. Its average benchmark score of 20454 is nearly identical to its nearest rival, the AMD Ryzen 5 5600, which scores 20468 and is 0.1 percent ahead. The AMD Ryzen 5 8500G scores 20425, which is 0.1 percent behind the Intel part. The AMD EPYC 9454P scores 20422, which is 0.2 percent behind. The AMD EPYC 7713 scores 20363, which is 0.4 percent behind. The tight clustering of these scores shows that the Core Ultra 7 258V performs in line with established desktop processors from the previous generation, despite being a mobile part.

The AMD Ryzen Embedded 9950X3D has no recorded benchmark scores, no average benchmark score, and no nearest rivals. Its percentile ranking of 50 is present in the database, but it is not backed by any measured results. The data cannot confirm any performance win for the AMD part. What the data does confirm is its specification-level advantages: 16 cores, 32 threads, a 5.70 GHz boost clock, 128 MB of L3 cache, and 24 PCIe Gen 5 lanes. These are the parameters that typically drive performance in heavily threaded and cache-sensitive workloads, but without benchmark scores, the magnitude of that performance cannot be quantified from the database.

The absence of head-to-head data means the comparison rests on specifications for the AMD part and on benchmark scores for the Intel part. The Intel part has a recorded memory bandwidth of 136.5 GB/s, which is higher than the AMD part's 89.6 GB/s, and it uses a smaller 3 nm process with a 17 W TDP. The AMD part counters with a larger core count, a higher boost clock, more L3 cache, ECC support, and a much larger PCIe lane allocation. The release dates place the Intel part in September 2024 and the AMD part in October 2025, a gap of just over a year. Both processors are marked as active in production.
