The lowest recorded Intel scores are Passmark find prime numbers at 185 and Passmark physics at 1565. No AMD scores exist to compare against, so the database cannot award a head-to-head win to either processor based on direct runs; the only measurable results belong to the Intel part.

Architecture Differences

The two processors differ at the architectural level. The AMD part belongs to the 9000 series, uses the Granite Ridge codename, and is listed under the Ryzen Embedded generation with Zen 5 (Granite Ridge). The Intel part belongs to the Core Ultra Series 2 and uses the Lunar Lake architecture. Both are built by TSMC, but on different nodes: the AMD part uses 4 nm and the Intel part uses 3 nm.

The core and thread counts separate the two clearly. The AMD part has 12 cores and 24 threads. The Intel part has 8 cores and 8 threads. The cache layouts also differ. The AMD part has 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3. The Intel part has 192 KB of L1 per core, 2.5 MB of L2 per core, and 12 MB of shared L3.

Memory support is another dividing line. The AMD part uses dual-channel DDR5 with a memory bandwidth of 89.6 GB/s and supports ECC memory. The Intel part uses dual-channel LPDDR5X with a memory bandwidth of 136.5 GB/s and does not support ECC memory. Both provide PCIe Gen 5, but the AMD part provides 24 CPU lanes while the Intel part provides 4 CPU lanes.

The integrated graphics differ as well. The AMD part includes Radeon Graphics. The Intel part includes Arc 140V. The AMD part uses AMD Socket AM5 and is classified as a desktop processor. The Intel part uses Intel BGA 2833 and is classified as a mobile processor. The AMD part has an unlocked multiplier; the Intel part does not.

The AMD part is built from 16,630 million transistors on a die size of 2x 70.6 mm². The Intel part has no transistor or die size record in the database. The AMD part was released on 2025-10-06, and the Intel part was released on 2024-09-23. Both are listed as Active production parts.

Where Each One Wins

The recorded benchmark data gives every measured win to the Intel part, because the AMD part has no benchmark scores. In the Passmark suite, the Intel part's strongest categories are data compression at 176686, floating point math at 57372, integer math at 42889, random string sorting at 21580, and multithread at 18887. Its Passmark single-thread score is 4018, its extended instructions score is 14717, its data encryption score is 13534, its physics score is 1565, and its find prime numbers score is 185.

In Cinebench, the Intel part scores 1596.5 in R15 multicore, 285 in R15 singlecore, 6739 in R20 multicore, 951 in R20 singlecore, 10301 in R23 multicore, and 1872 in R23 singlecore. In Geekbench, it scores 9325 multicore and 2100 singlecore. For single-thread work, the Intel part's recorded scores are 2100 in Geekbench singlecore, 1872 in Cinebench R23 singlecore, and 4018 in Passmark single thread. For multi-thread work, it records 9325 in Geekbench multicore, 10301 in Cinebench R23 multicore, and 18887 in Passmark multithread.

The AMD part's specifications indicate a desktop processor with 12 cores, 24 threads, 128 MB of L3 cache, ECC support, and an unlocked multiplier, but the database contains no benchmark runs to translate those specifications into measured wins. The Intel part is the only processor in this pairing with recorded data in every benchmark category.

The Verdict

Strictly from the recorded data, the Intel Core Ultra 7 258V is the only processor in this pairing with a measured performance profile. Its average benchmark score of 20454 places it in the 74th percentile of all CPUs, and its nearest rivals sit within 0.4% of that average score. The AMD Ryzen Embedded 9900X3D has no benchmark records, so the database cannot confirm any measured performance advantage for it.

The AMD part's specification sheet shows 12 cores, 24 threads, 128 MB of L3 cache, ECC memory support, and an unlocked multiplier, but those specifications are not accompanied by benchmark results. For a decision based on measured data, the Intel part is the only option with supporting evidence. For a decision based on unmeasured specifications, the AMD part offers the larger core, thread, cache, and ECC feature set.
