AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 5 238V Comparison

The AMD Ryzen Embedded 9900X3D and the Intel Core Ultra 5 238V occupy opposite ends of the computing spectrum. The database records no direct head-to-head benchmark results between these two parts, and the AMD chip has no recorded benchmark scores or rival listings. This analysis therefore relies on the recorded specifications and the available benchmark data for the Intel processor to establish a comparative framework.

Head-to-Head Benchmarks

Because the database contains no benchmark entries for the AMD Ryzen Embedded 9900X3D, a direct score-by-score comparison is impossible. The Intel Core Ultra 5 238V, however, has a complete benchmark profile. Its average benchmark score stands at 21981, placing it in the 75th percentile of all CPUs in the database. This performance level is closely matched by its nearest rivals: the Intel Core i7-11700F scores 21988 with a delta of 0%, the AMD Ryzen 5 3600X scores 21992 with a delta of 0%, the Intel Core Ultra 5 236V scores 21952 with a delta of 0.1%, and the AMD EPYC 9534 scores 21900 with a delta of 0.4%.

The Intel chip’s Cinebench results show its multi-threaded capability. In Cinebench R23, it records a multicore score of 15645 and a singlecore score of 2208. The Cinebench R20 run yields 6570 multicore and 927 singlecore, while the older Cinebench R15 test produces 1576 multicore and 222 singlecore. Single-thread performance scales consistently across these versions, indicating a stable architecture under varying workloads.

PassMark tests further characterize the Intel part. Its multithread score is 18407, while single-thread performance is recorded twice as 3890 in both the passmark_single_thread and passmark_singlethread tests. In specific computational tasks, the chip scores 38889 in integer math, 53160 in floating point math, 13072 in data encryption, 176532 in data compression, 15377 in extended instructions, 174 in finding prime numbers, 1546 in physics, and 21585 in random string sorting.

The AMD Ryzen Embedded 9900X3D, with its 12 cores and 24 threads, would presumably deliver strong multi-threaded performance given its specifications, but no measured data exists to confirm this. The Intel Core Ultra 5 238V, with 8 cores and 8 threads, shows no simultaneous multi-threading advantage, yet its benchmark scores place it competitively among desktop processors from previous generations.

Where Each One Wins

The Intel Core Ultra 5 238V demonstrates its strengths in the recorded benchmark data. Its singlecore Cinebench R23 score of 2208 and PassMark single-thread score of 3890 indicate robust per-core performance. The chip’s 3 nm process node from TSMC and 17 watt TDP point to high efficiency, a critical factor for mobile workloads. Its integrated Arc 130V graphics provide a built-in visual solution, and the 8 MB shared L3 cache supports its computational tasks.

The AMD Ryzen Embedded 9900X3D, by contrast, wins on raw specification in several areas. Its 12 cores and 24 threads double the Intel chip’s thread count, which suits heavily parallel workloads such as server virtualization, content rendering, and database processing. The 128 MB L3 cache, enabled by the 3D V-Cache design implied by the X3D suffix, offers a massive data reservoir for cache-sensitive applications. The 5.50 GHz boost clock exceeds the Intel chip’s 4.70 GHz, and the 4 nm process node from TSMC, while slightly larger than Intel’s 3 nm, still represents advanced manufacturing. The AMD processor supports ECC memory, a feature absent from the Intel part, and its 24 PCIe Gen 5 lanes vastly outnumber the Intel chip’s 4 lanes.

The Intel chip wins in power efficiency. Its 17 watt TDP is drastically lower than the AMD chip’s 120 watt TDP, making it suitable for thin-and-light laptops and fanless designs. The AMD chip targets embedded systems that prioritize compute density over power conservation.

Architecture Differences

The two processors diverge fundamentally in architecture. The AMD Ryzen Embedded 9900X3D belongs to the Ryzen Embedded series from the 9000 series, with the codename Granite Ridge and a generation listed as Ryzen Embedded (Zen 5 (Granite Ridge)). The Intel Core Ultra 5 238V belongs to the Core Ultra Series 2, with the architecture and codename Lunar Lake and a generation listed as Ultra 5 (Lunar Lake).

Manufacturing processes differ. The AMD chip uses a 4 nm node from TSMC, while the Intel chip uses a 3 nm node, also from TSMC. The AMD processor integrates 16,630 million transistors across a die size of 2x 70.6 mm². The Intel processor has no recorded transistor count or die size in the database.

Cache hierarchies present stark contrasts. 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 cache per core, 2.5 MB of L2 cache per core, and only 8 MB of shared L3 cache. The AMD chip’s total L3 cache is 16 times larger than the Intel chip’s, a difference that heavily favors the AMD part in workloads with large working sets.

Core configurations differ as well. The AMD processor has 12 cores and 24 threads, enabling simultaneous multi-threading. The Intel processor has 8 cores and 8 threads, with no multi-threading support. The AMD chip’s base clock is 4.40 GHz with a boost clock of 5.50 GHz, while the Intel chip’s base clock is 2.10 GHz with a boost clock of 4.70 GHz. The AMD chip’s multiplier is unlocked, allowing overclocking, whereas the Intel chip’s multiplier is locked.

Memory support varies. The AMD chip supports DDR5 memory with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. It also supports ECC memory. The Intel chip’s memory support is listed as unknown and dependent on the motherboard, with a dual-channel bus and no ECC support. The AMD chip uses AMD Socket AM5, while the Intel chip uses Intel BGA 2833. The AMD chip provides 24 PCIe Gen 5 lanes (CPU only), while the Intel chip provides 4 PCIe Gen 5 lanes (CPU only). Integrated graphics differ: the AMD chip uses Radeon Graphics, while the Intel chip uses Arc 130V.

Release dates separate the parts by roughly a year. The Intel Core Ultra 5 238V launched on 2024-09-23, while the AMD Ryzen Embedded 9900X3D arrived on 2025-10-06.

The recorded data confirms two distinct design philosophies. The AMD Ryzen Embedded 9900X3D prioritizes raw throughput, cache capacity, and expandability for embedded and desktop-class workloads. The Intel Core Ultra 5 238V prioritizes efficiency, compactness, and integrated graphics for mobile systems. Without benchmark data for the AMD part, quantitative performance comparisons remain limited to the Intel chip’s measured scores and its standing among rival processors.
